AI's don't pray! They only make calculations to win!— Ai
Ai is a small digital humanoid being. Like other Ignis, Ai has markings over his body, in shape of lines and circles, which are tinted with a purple color. When he becomes angry, Ai turns into a fiendish shape, with six tentacles, a large yellow eye and mouth, with two of his eyes on the center of his body.
When Varis' "Cracking Dragon" ate his body, Ai was reduced to an eye. However, when he ate Varis' arm off, Ai regained his body.
Ai is a mischievous, cocky, playful, energetic, sometimes self-centered, arrogant, and snarky AI who gets carried away easily and likes to joke around. Despite his occasional cockiness or annoying moments, he is actually quite funny, loyal, resourceful, and amiable. According to his own words, he is disliked by his own people because he was more laid-back than them and didn't perform his job. Ai struggles to understand humans' way of thinking that often seem completely illogical compared to his algorithm based way of thinking. However, he is helpful and can be more serious at times such as making observations both in and outside of duels. He also has a tendency to panic when Playmaker is about to lose.
Ai frequently tries to interact with other AIs, showing a more social side but is always left disappointed because they're not as capable of free thinking as himself. He also enjoys insulting and taunting Playmaker's opponents, as well as trying to manipulate them into falling for Playmaker's strategies, though these attempts of his to help are more often detrimental than not. He does seem to show concern for Yusaku when the latter’s on his last legs, either genuinely for his safety or Ai needing to survive to return to Cyberse.
As an Ignis, who created Cyberse, Ai has some degree of control over it. He is the only one who knows its location and can unlock data from it to start a Data Storm. Ai is shown to be far more sophisticated than other AIs, being fully capable of thinking and acting on his own free will and showing emotion; because of that, Ai is considered to be an actual living being. According to Kolter, Ai is built out of highly complicated algorithms that even Yusaku couldn't fully decode. Ai's memories are stored in the form of video logs. However, Ai's level of free will is limited by the fact that he is still a computer program, as such he can't comprehend why humans do actions that would seem illogical and contradicting with each other.
Ai's Skill is Storm Access which is given to Yusaku after being trapped in Yusaku's Duel Disk. Whilst trapped in the Duel Disk, he can also act as a Duel AI. Inside Link VRAINS, Ai is shown to be able to transform into a monster, which he did to devour a Knight of Hanoi member and a card infected by Hanoi.
Ai has the ability to sense a Knight of Hanoi's presence through the cards in their Deck, such as when he knew right away that Gore was pretending to be a Knight and when he discovered the Hanoi-affected card in Blue Angel's Deck and could tell when it was drawn.
After Playmaker defeated Varis, Ai regained his full body and can materialize himself in the real world, though he still can't leave Yusaku's Duel Disk. In Link VRAINS, he's able to enlarge to human size while still linked to Yusaku's Duel Disk and regenerate parts of an avatar. He can even enhance the D-Board to higher speed and act as a shield, at the cost of it destroying him. Ai can regenerate himself, but in a fast data recovery causes him to be smaller.
Ai has more abilities, as each Ignis is associated with an element. It is currently unknown what Ai's element is. However, looking at his section of Cyberse as a large, dark gorge, and include that the Ignis are based on the Duel Monster Attributes, it can be debated that his element is DARK. This can also be supported by Linkuriboh, a Cyberse Monster Ai interacts with, being a DARK Attribute Monster.
Ai was created by Dr. Kogami, the scientist who created the Ignis. The Ignis were developed by watching the six test subjects Duel, with Ai modeled after Yusaku. Eventually, Ai and the other Ignis evolved and created the Cyberse World, as well as the Cyberse monsters. Their progress worried Dr. Kogami who created Ignis to help humanity, and predicted through his simulations that the AI and humanity would become enemies. Despite this, Ai and the other Ignis continued to create their world, each with a sector based on themselves. In Ai's words, the Ignis would never try to harm humanity, and would rather live in their own world. Ai, however, was laid-back and didn't do his job as the other Ignis did, which made him less-liked by his kin.
Five years prior to the start of the series, the Knights of Hanoi launched an attack against the Cyberse and captured the Ignis protecting it, except for Ai who wasn't present. Ai arrived, noting that it was a good time to be hated by his own kind. He stole vital information from the Cyberse and hid it within himself, disconnecting it from the rest of the network which forced Hanoi to stop the attack before he was crushed by a "Cracking Dragon" (in the dub, this scene was replaced by the flash of data). However, his eye survived. Ever since, he had been running from both the Knights and SOL Technologies.
Ai was in LINK VRAINS, and watched certain events, like Playmaker confronting a Knight of Hanoi. Later, while being pursued by SOL Technologies and the Knights of Hanoi, Ai fell into a trap created by Playmaker, who saved him by absorbing him into his Duel Disk. Yusaku explained Ai would be their hostage, and made it clear Ai could not escape. Yusaku went into LINK VRAINS as Playmaker to confront the Knight of Hanoi, which displeased Ai for returning into the danger. Playmaker showed Ai, and threatened to delete it if the Knight did not stop his attack. Thus, Ai was turned into a Dueling AI. thus necessitating the defeat of Playmaker in order to recover Ai. Ai doubted that Playmaker's Deck was strong enough to defeat the Knights' "Cracking Dragon", but Playmaker doubted Ai's words and told him to pray for the victory. Ai declared AI do not pray before stirring up a virtual wind called "Data Storm" that initiated a Speed Duel.
Before the Duel began, Ai explained Playmaker how Speed Duels worked but didn't mention Skills. Throughout the Duel Ai repeatedly tried to offer support for Playmaker, only for Playmaker to keep telling him to shut up and remind that he was holding Ai hostage. When they sucked into a tornado within the Data Storm, Playmaker figured out that Ai not mentioning skills and bringing him into the tornado were part of his calculations. Ai confirmed this, and activated Playmaker's skill "Storm Access", which allowed them to obtain "Decode Talker" so that Playmaker could defeat the Knight. The Knight attempted to self destruct and kill Playmaker, but Ai turned into a monster and devoured the knight to save Playmaker. He suggested Playmaker should log off soon. Yusaku and Kolter spent the next few days trying to figure out Ai' programming and nicknamed him "Ai", a pun on "A.I." and "eye". Eventually Yusaku found footage from some of Ai's memories, which Ai himself didn't understand except for Varis being the leader of Hanoi. Scanning those recordings caused Varis to sense Ai and try to find him, but Kolter shutting off Café Nagi's power prevented him from finding them. The next day, Ai was left at Yusaku's house in a storage shelf, there he tried to convince Roboppy to set him free.
Ai panicked when Yusaku returned home and had Roboppy put him back on the shelf. When Yusaku found them, Ai told Yusaku that had arrived home early, to which Yusaku said a Knight of Hanoi appeared and revealed a secret room he used to go to LINK VRAINS. As soon as they arrived, both Playmaker and Ai quickly figured out the Knight was fake. The "Knight" revealed himself to be Gore, who wanted to challenge Playmaker. Ai looked up information about Gore, Playmaker was uninterested and attempted to log out but a program from SOL prevented him from doing so, so he was forced to Duel Gore. During the Duel, Ai continued researching Gore and found out that Gore donated most of his money to the orphanage where he grew up. When Gore let himself take 2000 Damage when he had the chance to avoid it, Ai was confused about why humans make illogical choices. Playmaker said it was because of their hearts, but didn't explain what that meant because Ai' algorithm-based thinking wouldn't understand it.
When Kolter found out that Aoi Zaizen, Yusaku's classmate, is "Blue Angel", Ai helped Yusaku locate her while they were at school. Ai forced Yusaku to join the Duel Club and tried to interact with Aoi's Duel Disk AI. The next day Ai noticed something strange about Aoi's AI so he sent her a text message on Playmaker's behalf challenging Blue Angel to a Duel, then tricked Yusaku into going into VRAINS to confront Blue Angel. There, he explained that Hanoi must've planted a card into Blue Angel's deck to use her as bait for Playmaker. During the Duel, Ai was horrified when Blue Angel was affected by Hanoi's card and warned Playmaker that if the Duel continued much longer, Aoi would suffer permanent brain damage.
After the Duel concluded Ai devoured Hanoi's program and detected that they had infected Aoi with a virus to keep her comatose. Later Ai told Yusaku and Kolter that the only way to remove the virus was to get an anti-Virus from Hanoi. Right after that, a "Blue Angel" impostor appeared demanding a rematch. Despite knowing that it was a trap, Yusaku went to confront the impostor because he could get a chance to obtain the anti-virus. Upon arriving however, the impostor turned the entirety of VRAINS into a trap to capture Playmaker and revealed herself to be Ghost Girl. Akira Zaizen appeared and tortured Playmaker, believing him to be the culprit of Aoi being comatose and swore to reclaim Ai. Playmaker and Ai tried to explain that Hanoi were the real culprits to no avail, until Varis appeared and blackmailed Akira into releasing Playmaker so they could Duel. During the Duel, Ai noted that Varis didn't have an AI. Varis said that he didn't trust AIs and that Ai must be destroyed otherwise the virtual fiction of VRAINS will destroy the world. When Varis used "Storm Access", Ai was shocked that because that was his signature program, but also called out Varis' hypocrisy of wanting to destroy Cyberse while borrowing power from it, Varis countered that claiming that he was "countering poison with poison".
As the Duel progressed, Varis gained the upperhand, and worrying that they might lose, Ai led Playmaker to another Data Storm, where the two obtained a dragon. However, Varis activated the Trap Card, "Remote Rebirth", and combo-ed it with the effect of "Topologic Bomber Dragon", ending the Speed Duel in a draw. Following that, Varis dragged Playmaker and Ai inside a Data Storm, where they began a Master Duel. As the Duel went on, Varis activated the effect of "Fire Prison", eliminating all Cyberse cards from the field, as well as making Ai seemingly vanish into thin air. Ai woke up at sea, and remembered how "Fire Prison" erased his program. Though he was surprised by the surroundings, Ai felt somewhat sleepy, even if he never had felt this before. When Playmaker called out to him, Ai woke up and came back after Playmaker summoned "Firewall Dragon" and "Fire Prison" was destroyed. Ai was concerned if Playmaker lost, and panicked to see he only had 600 LP left. Ai was amazed to see the two dragons, until Varis used the effect of "Borreload Dragon" to take control of "Firewall Dragon".
Ai was frustrated how "Firewall Dragon" failed to remove "Borreload Dragon" from the field, and reminded Playmaker to protect his own dragon. He also reminded Playmaker how they had to count everything on their next draw. Ai was pleased when Playmaker used "Battle Buffer" to negate Varis' "rokket" monsters' effects and could not use them as ammunition for "Borreload Dragon". He had "Firewall Dragon" attack "Borreload", despite the ATK disadvantage. This was part of the strategy for "Encode Talker" to destroy Varis' dragon. Ai watched as "Firewall Dragon" defeated "Borreload Dragon", and Varis as well. He then became vicious and tried to devour Varis, even biting his avatar's arm off but a lightning stroke, restraining Ai and cursed Varis for leaving. Later on, Ai noticed Yusaku sleeping, and called out how lazy he was. Kolter replied heroes need rest, too, though Ai started bragging how heroes needed to be just like him. When Kolter went to analyze the program, Ai called him a pervert for looking into his private parts, and refused to say anything about the program he ate off from Varis. Later, Ai woke up and explained to Yusaku and Kolter he was alive, but they wanted proof. Ai then started to focus and a golden light appeared out of Yusaku's Duel Disk. Ai came out, with his whole body intact, stating his pride how he managed to recover his body back. Yusaku and Kolter were unamused by his small size and went to analyze if Ai had any memories of his past. Ai was displeased by their ignorance, wanting them to show some reaction to seeing his true self.
After Yusaku left him home for being annoying, Ai flexed his muscles to impress Roboppy, who was amused. Ai commented how dumb robots were, which insulted Roboppy. However, Ai swore once he was completed, they would "start doing that again", which made him and Roboppy blush. Ai "played" with Roboppy, and claimed Yusaku wouldn't watch them, since he was deep in a thought. After Yusaku got a message from Kolter, he took Ai with him to the food truck. There, the two read how Ghost Girl challenged Playmaker, with her access to the data bank and Playmaker's Ai as wagers. Ai stated they didn't have to accept her challenge, but Playmaker nevertheless did so, as he was interested in the data from SOL Technologies' data bank. Inside, Ai was displeased the two initiated the Duel. Ai reminded Playmaker while he did not know anything about Ghost Girl, she must've studied his tactics well. During the Duel, Ai pointed out how Ghost Girl reinforced her defenses, and even set three Trap Cards that would stop them. As Ghost Girl initiated the Battle Phase and claimed she would win in that turn, Ai laughed, as she would make 2400 LP damage. Both Playmaker and Ghost Girl scolded Ai for such thinking; Playmaker claimed no Duelist would make that simple math error, making Ghost Girl wonder why was everyone after this dumb AI. Ai was offended, while Playmaker pointed out she did bring out "Altergeist Meluseek". The latter attacked directly and destroyed "Cyberse Wizard", allowing "Altergeist Marionetter" attack directly, and allow "Altergeist Primebanshee" to do so as well. Ai started panicking, as its fate was on the stake.
Ai yelled at Playmaker that Ghost Girl's next attack would deplete all of his LP. As Playmaker Special Summoned "Lockout Gardna", Ai knew they would have enough LP to continue and even use Storm Access, and exclaimed how "bad" this would be. However, Ghost Girl knew Ai was just pretending, and decided not to attack. Ai was in shock, and Playmaker told him this acting stinked, making Ai sniff himself. Ai continued watching the Duel, and commented how Ghost Girl was foiling their strategies, and wondered what her Skill was. Using Secret Cure, Ghost Girl increased both her and Playmaker's LP by the ATK of "Altergeist Meluseek", making Ai comment how the latter punished them before already. Still, Playmaker paid the LP to activate "Scan Doll" and Ai praised him, encouraging him to use Storm Access. Since Ghost Girl was in the Data Storm, Ai was surprised that Playmaker went to save her, even if they could be swallowed inside, too. Coming out of the Data Storm, Ai commented how Playmaker behaved like a hero. With "Excode Talker" brought out and able to attack twice, Ai smiled, claiming it is over for Ghost Girl. At the end of Duel, Ai explained it was a stressful battle, and would've ended in defeat if it wasn't for him. After Ghost Girl left, Ai asked what was in the SOL Technologies' data bank. Playmaker admitted he did not know, but hoped there was some info about himself, ten years ago.
The next day, Yusaku was searching for Aoi, but noticed she was not present there, nor in LINK VRAINS. Ai thought her brother was blocking her the access to LINK VRAINS, to prevent any further danger that might harm her. However, Ai also wondered why was Yusaku concerned about "that cutie", as Yusaku wished that she shouldn't give up on Duels. The following night, Kolter created a link to the mother computer. Yusaku started hesitating to enter, making Ai surprised, since he did wish to find more out and even won the program as a bet from Ghost Girl. Ai claimed he did warn them there were traps from the start, but Kolter explained Yusaku was just being careful. Ai expressed his annoyance, and went with Yusaku into the LINK VRAINS. While inside the system, Ai saw how empty the place was, and wasn't impressed by the rope Playmaker held. Soon, Ai warned Playmaker about the security traps, which were sent to hamper their path. After passing through Area A, Ai was glad they succeeded, but was shocked to see a Data Storm inside the network. Playmaker and Ai were pulled towards the Data Storm, with their rope shattering and alerting Kitamura. Playmaker and Ai were "visited" by two AI prototypes, who went to Duel them, even if Ai reminded them Duels were one on one. Playmaker avoided them and proceeded further, though one of the AI-s intercepted him. The two began a Duel, in which the AI prototype dropped all of Playmaker's hand with "Tentacluster Nautilus". Ai told Playmaker had no luck, thinking he was bad at old maid, but Playmaker shushed him. The two were attacked by the other AI prototype until Blue Angel came to stop the AI-s. When Playmaker shaved his LP down to 1000, AI encouraged him to enter the Data Storm, wondering what monster would he obtain. Inside the data bank, Ai and Playmaker were surprised to see Akira, who expected Playmaker to arrive there.
Ai pointed out the core of the data bank was where SOL Technologies' information was processed and released. Hearing Ghost Girl's plans, Ai thought Ghost Girl lost on purpose to hand them the backdoor route, but Ghost Girl corrected it that she still had the opportunity to obtain Ai. Regardless, she was fine with either outcome, making Ai curse her for being so cunning, which Ghost Girl took as a compliment. When Akira refused to hand over the data from the bank, Ai started to complain, claiming he is the great Ignis everyone was searching for. Akira wondered if Ai actually had free will, like Varis told them. Ghost Girl told them Akira was demoted, which made Ai amused how much he sacrificed himself to look after his sister. Since Akira refused to hand over the data, Playmaker challenged Akira to a Duel, betting Ai for the data, which Akira accepted. Ai was displeased, as being bet was a normal thing to it. As Akira reinforced his defenses, Ai noted Akira was a stiff man, just like his strategy. As Ai swapped "Tindangle Base Gardna" for "Tindangle Hound", Ai started complaining until seeing how scary the latter was. "Tindangle Hound" roared as its effect activated, making Ai feel woozy, but Playmaker silenced Ai. Playmaker brought out "Flame Administrator" and destroyed "Tindangle Hound", with Ai mimicking Playmaker's pose. However, it cursed, as Akira revived his "Tindangle Hound", via "Tindangle Angel", and ended the Battle Phase. Ai realized Akira played a Flip Monster deck, with unique strategies. Since Playmaker refused to give up, Ai encouraged him to crush Akira. Ai admitted Akira's monsters hurt his pride, seeing its power continued lowering Playmaker's monsters' ATK.
Playmaker destroyed Akira's monsters with "Link Hole", and Ai taunted Akira for being unable to use his Flip Monsters' effects. However, Ai started panicking when "Decode Talker" was destroyed and "Tindangle Acute Cerberus" was summoned, whose ATK was boosted to 3000. "Tindangle Acute Cerberus" attacked "Firewall Dragon", and Ai feared he and Playmaker would lose, so the latter protected "Firewall Dragon" with "Doppler Phase Coating". Akira protected his own monster with "Gergonne's End", so Playmaker tried to have "Firewall Dragon", enhanced with "Alert Lancer", attack "Tindangle Token" to finish the Duel. Ai smiled for the victory, until Akira protected himself with "Morley's Shield". Ai continued panicking when Akira played "Nagel's Protection" to protect his Tokens, and even doubling the damage "Tindangle Acute Cerberus" dealt, lowering Playmaker's LP to 500. Ai yelled to Playmaker to do something, and even wondered if there was anything that can be done to get them out of the situation. Playmaker told Ai to stop panicking, asking if it even was an AI, making the latter furious why he was so calm. Playmaker claimed if Ai was so worried about losing, it should consider about finding a new home. Ai replied he didn't think of that, since he had Playmaker as a friend to help him out. Playmaker claimed they were no friends, stating Ai should behave like other AI-s. This crushed Ai, seeing Playmaker was colder than AI-s. Ai started acting like a dumb AI to amuse Playmaker, though he also wished to know about the incident from ten years ago. Hearing Playmaker was a part of Hanoi Project, Ai started to ponder thoughts about it. He was also shocked to hear SOL Technologies' data bank contained the name of the mastermind behind the project.
Ai realized Playmaker had two parallel choices who confirmed this, exciting Ai, as their opinions matched. As Akira declared an attack on "Firewall Dragon", Ai panicked once more, but was silenced by Playmaker. As "Doppler Phase Coating" was removed, Akira's Battle Phase ended, and Ai was impressed, seeing Playmaker could survive. As Akira summoned another token to power up "Tindangle Acute Cerberus", Ai ignored that, thinking that was a pointless move, as "Firewall Dragon" would attack Akira directly. Instead, the latter activated "Euler's Circuit" to stop Playmaker from attacking. Ai lost hope, thinking he would be turned over to SOL Technologies. However, as the conditions for "Gergonne's End" were fulfilled, Akira destroyed all monsters linked to "Tindangle Acute Cerberus" to defeat Playmaker. However, the latter's "Secure Gardna" prevented the damage, and Ai taunted Akira for falling for the trick. Ai bragged his acting made this possible, but Playmaker brushed him off, as it was poor acting that nearly made Akira suspect something wrong. Despite the advantage, Playmaker used "Recovery Sorcerer" to bring back "Secure Gardna". Ai questioned this, as Playmaker could simply make a direct attack with "Firewall Dragon", but was told a Duel is more than just winning or losing. With Akira's defeat, Playmaker walked pass by Akira and Blue Angel, having Ai eat away SOL Technologies' data. Ai was surprised his name was mentioned, and ate the data, to the point of becoming stuffed. Outside, Kolter praised Yusaku and Ai, the latter being happy he was praised. The two hacked into Ai, and found out the Hanoi Project's leader was Dr. Kiyoshi Kogami, an employee from SOL Technologies, who alone worked on the project in secrecy. Ai doubted the man could have done this on his own, and thought Akira was involved, but Kolter reminded him Akira, back then, was 16 and was not employed at SOL Technologies. The two continued browsing, and were shocked to see Dr. Kogami died seven years ago.
After being left home again, Ai promised to tell a story to Roboppy, who wanted to listen more, since she did help Ai out in "secret things". Both started blushing and giggling. Ai told the story of the recent events: the confrontation with Ghost Girl, entering the SOL Technologies' data bank, battling the AI prototypes and facing the former security-in-chief, Akira, himself. Ai credited himself for some of Playmaker's contributions, amazing Roboppy, until he claimed he wished everyone to fight, with him as the bet. He also thought Playmaker as some sort of a fiend, though Roboppy stated he was just cold-hearted. After he told the story, Ai admitted he was uncertain what would they do next, since nobody else but Dr. Kogami knew about the incident.
Playmaker and Ai watched an eclipse blocking the virtual sun in LINK VRAINS. Ai remembered people in the ancient past were scared of such events, and was surprised people, even today, were still afraid. Playmaker replied people remain the same, unlike technology that advances. The latter proclaimed the light was blocked by darkness, and confirmed to Ai he meant about the Lost Incident. He would not let the incident be buried in darkness, and would uncover the truth. At school, Yusaku spoke with Naoki Shima, who mentioned the "Anothers" incident. Ai thought this had relations to Blue Angel, but Yusaku shushed him, since Naoki could hear him. Inside the van, Kolter showed to Ai and Yusaku the footage of a camera, when a person turned into an Another, which happened six minutes before midnight. Ai noted there were no white hands taking the person into LINK VRAINS. Kolter told them the person had not recovered yet, and showed pictures of more Another patients in the hospitals. Ai and Yusaku knew this was the same accident with Blue Angel, who was infected by a virus.
Kolter believed someone wanted people to be turned into mindless people, but has not find out what happened to their LINK VRAINS' avatars. Kolter showed more data, and Yusaku analyzed all of the Anothers were great Duelists with old-type Duel Disks, and all of them were hackers, too. The trio realized Playmaker, or Ai, were the targets. Yusaku reminded the importance of uncovering the truth behind Lost Incident, and as noted by Ai, they had to stop people from becoming Anothers. Ai noted Yusaku was a cool hero of justice, even if the latter claimed that was unnecessary. Kolter showed a list of possible targets, from which the first was Makoto Kimishima. Yusaku traced the person to his house, and saw lights at his window. Yusaku broke through into his room, and saw he became a victim. In addition, he and Ai watched Makoto's avatar inside LINK VRAINS being confronted by a person, who wished to know if he was Playmaker and had Ignis. Yusaku and Ai saw the person casted some glitter, causing Makoto to fall asleep and fall off the cliff, but was saved by Gore. Playmaker watched as Gore confronted the person, Dr. Genome, who placed the virus into Makoto, only to draw Playmaker out. At the van, Kolter and Yusaku watched the Knights of Hanoi Dueling people, and turning them into Anothers. Yusaku decided to Gore into LINK VRAINS, even if Kolter believed he would be at a disadvantage, and Ai wished to feel secure. The group watched as Dr. Genome came, confronting "Playmaker", who revealed himself as Gore, and challenged Genome, betting Playmaker's identity.
Yusaku, Kolter and Ai watched Gore confronting Dr. Genome. Since Gore claimed to have known Playmaker's identity, Kolter remembered Yusaku did run into Gore at the hospital, but Yusaku claimed it was impossible. Once Gore equipped himself with a mask and declared himself as "Dark Onizuka", Ai thought that was a tacky thing to do. Yusaku and Kolter realized Gore changed his battling style to a heel, and would not hold back. Ai was surprised to see Gore actually had his "Gouki Riscorpio" attack "Helixx Marmotroll", causing the former to be destroyed, since it had less ATK. However, Ai noticed this was to have Gore gain an advantage, as 500 LP was inflicted on Genome, and Yusaku added that was how a heel fights. Ai noticed Gore started using his brain to win, while Yusaku noted Gore still wanted to win, in his own way. Just as Gore was to win, Genome played "Regeneration Cure" to stop the damage, and everyone saw Genome had the advantage. As Genome tributed "Helixx Necro Darwin" to defeat Gore, Yusaku became displeased. Ai suggested he could enter LINK VRAINS to save Gor. Yusaku who saw Gore barely saving himself with "Gouki Octostretch", decided to take Ai's advice.
Playmaker and Ai came to LINK VRAINS to help Gore. Dr. Genome noticed the Ignis was here, who claimed he had a name, Ai. Genome was surprised, and saw Ai was domesticated, like a pet, who denied that. Later, Playmaker and Ai suggested a person, who wanted to fight the Knight of Hanoi, to Gore home. The man did so, while Playmaker confronted the Knight of Hanoi. After the defeat, Playmaker demanded the virus-removal program. The Knight did not have it, so Playmaker questioned who was the virus' creator, and Ai threatened the Knight to delete him. However, someone else dissolved the Knight before he could reply. At the van, Ai was amused to read Kitamura was criticized for his failed efforts to stop the Knights of Hanoi. He also read the people demanded some action to be taken for someone responsible in SOL Technologies. Yusaku shushed Ai, since he was interfering with their work. After Yusaku returned, Kolter found nothing new. Ai believed Kolter gave up, who replied he was just getting started. Later, Ai watched Blue Angel Dueling Baira. He noted Blue Angel was cornered, but Yusaku shushed him, since they were still working.
Yusaku showed the woman behind an Another victim, and compared her to Aoi Zaizen's doctor, Kyoko Taki. Ai confirmed this, but wondered if she would help the victim because she was a doctor. Yusaku reminded Ai to listen in the end, as he proclaimed she was one of the Knights of Hanoi. Yusaku went to her apartment, worrying Ai, as the place could be the Knights of Hanoi's headquarters. Yusaku replied it was more reason for him to go, and Ai even asked if he was good at fighting. Inside, the two passed by a robot, and Ai hacked into the security system, opening the apartment. Ai saw nobody, but Yusaku shushed him. Continuing on, the two found a room with a pod, in which Kyoto Taki was, logged in LINK VRAINS as Baira. When she logged out, Ai proposed to tie her up, but she appeared next to Varis, who punished her. Yusaku thought she released the virus-removal program because she felt guilty, a feeling Ai did not understand.
Ai boasted he couldn't be captured, and laughed with Roboppy, thinking how Yusaku would be surprised when he saw them. Later, he was at the van with Yusaku and Kolter. The next day, Yusaku spoke with Naoki, who wished to battle the Knights of Hanoi. Yusaku knew Naoki was scared, and knew Naoki came to ask him for help. Naoki was furious and stormed out, and Ai noted Yusaku went too far on him. When Yusaku came to the van, Kolter showed him someone has played his "Cyberse Wizard". Kolter identified him as Lonely Brave, which Ai thought as a cool name. When Yusaku showed his "Cyberse Wizard", Ai touched it and sensed the data from the card was missing. Ai thought Lonely Brave was the mastermind, and defeated the Knight of Hanoi to lure Playmaker out. Brave Max was soon interrogated by the mastermind, Faust, and called out to Playmaker to Duel him. Yusaku went to grab his Duel Disk, but saw it was gone. Ai logged on the screen, and showed he was on the Duel Disk, which Roboppy modified it with a drone. While Yusaku noted the device felt heavier, Ai explained he was searching for Naoki, though the data of "Cyberse Wizard". Yusaku realized Ai even knew this would happen, which offended Ai, seeing Yusaku was even accusing him. Regardless, Ai showed the location, where Naoki was captured. Ai got distracted by another drone, and nearly crashed into the building. Yusaku called out to him, and Ai returned to the van. Yusaku grabbed the Duel Disk and left Kolter to rescue Naoki, while Yusaku logged in to LINK VRAINS.
Playmaker confronted Faust, who denied having stolen "Cyberse Wizard" and giving it to Brave Max. Playmaker was confused, but Ai reminded him that was not important, and had to defeat Faust, who summoned the Data Gale. Playmaker noted it was just like during Blue Angel and Gore's Duels, and Ai noted this prevented them from returning home. Faust started the Speed Duel with summoning three "Motor Worm Tokens", and Ai sensed Faust was going all-out from the start. As "Cyberse Wizard" destroyed "Motor Worm Spreader Queen", Ai waved goodbye to her until Faust revived her with "Worm Revival". Shockingly to Ai, Faust used "Egg Clutch" to turn "Cyberse Wizard" into an Insect monster. Ai wondered if there was nothing they could do, and repeated this to Playmaker when he ended his turn. Due to "Egg Clutch", Faust tributed his "Motor Worm Token" to summon two new tokens on Playmaker's field, and Ai counted the queen got 700 additional ATK. The queen attacked Playmaker, who halved the damage by using "Urgent Link". Ai pointed out he barely survived with 50 LP left, though Playmaker stated it was still enough to fight. After destroying "Wormhole Defense", Ai encouraged Playmaker to use Storm Access skill. After Playmaker won, he repeated "humanity's future" Faust spoke of, though Ai didn't know anything of that. After the Duel, Yusaku went to rescue Naoki, who complimented him. He also spoke about Playmaker rescuing him, and Ai told Naoki talks too much. Yusaku, however, wondered if Ai was the one that put him in danger by giving Naoki his "Cyberse Wizard".
Since Yusaku felt uneasy, he could not sleep and went to Kolter's van. Ai smiled at Yusaku, thinking how cute he was, but Yusaku ordered him to be quiet. Regardless, he also agreed with Yusaku something bad would soon begin, as Yusaku believed Varis would make his move soon. Yusaku and Ai, in real life, sensed something wrong in LINK VRAINS. Later, Ai saw that Kolter lost a customer with a red triangle on his right arm. Ai claimed Kolter needed a mascot, who claimed Ai would make a terrible mascot. Kolter noted Anothers' incident has been resolved, but also reminded Varis was still out there. Ai thought Varis had retreated, but Yusaku doubted that. Suddenly, Yusaku and Ai felt a pulse within LINK VRAINSS, and the latter noted Yusaku had Link Sense. Yusaku asked Kolter to scan through the network. Kolter worked on scanning, and just as Yusaku and Ai sensed another pulse, Kolter saw LINK VRAINS infrastructure was changing. Yusaku decided to visit LINK VRAINS, even if Ai felt a bad omen ahead. Ai tried to convince Playmaker things would go bad and they should return home, but Playmaker was focused on finding the cause. Once again, they sensed the pulse coming from the network.
Finding some data fireflies, Playmaker traced them to a spot. As the data fireflies stopped, Ai thought they were taking a break. The two were visited by Ghost Girl, who wasn't particularly pleased Ai and Playmaker were present, too. The data fireflies opened a path, though which Ghost Girl entered, and Playmaker joined in, too. Finding a fork in the path, Ghost Girl saw her data fireflies went to the path on the right. Ai thought they could settle this with a game, which amused Ghost Girl, who credited the AI. Ai explained he had a name, and Ghost Girl thought his name was just a pun. Ghost Girl told the one that chose the "lovelier" card from her Deck could choose the path. Ai was confident in his skills, but had his doubts that Ghost Girl could cheat, who told there wasn't anything beneficial in that. Ghost Girl shuffled her Deck, and let Ai draw a card. Ai declared "Destiny Draw", only to choose "Fake Trap". Ghost Girl claimed the card was nothing her favorite, and didn't even choose to draw a card. She bid farewell to Ai and Playmaker, going to the path on the right. Ai was displeased he chose "Fake Trap", but Playmaker knew that Ghost Girl cheated, by using a Deck filled with bad cards. Ai was even more depressed he was cheated off once more, but Playmaker reminded the importance of their mission, and continued on. They were ambushed by a data giant, who went after them, making Ai even panic. While dodging the data giant's attacks, Playmaker and Ai sensed the pulse was getting stronger, and felt a danger was coming.
Playmaker continued running away from the data giant, and Ai told him to run faster. The two ran to a dead end, and just as the data giant went to attack them, it disappeared in a veil of light. Ai was glad they were saved, while Playmaker noticed another abnormality. Playmaker jumped in the crack, and Ai noticed that was the path that Ghost Girl took. The two watched as Ghost Girl was defeated by Varis' "Topologic Trisbaena". Ghost Girl glowed with a red light, and started vanishing. She warned Playmaker of Varis and his new card before disappearing. Ai and Playmaker were terrified, and were soon visited by Varis behind bars. Playmaker yelled at Varis, while Ai pointed out the place was collapsing, and they swore to protect Ghost Girl's data. Playmaker ignored Ai, who forced Playmaker to log out. Yusaku and Ai joined Kolter, and watched hundreds of tentacles wrapped a beam that was shot in the sky and destroyed LINK VRAINS' cyberspace.
Yusaku, Kolter, and Ai watched as the tower appeared in LINK VRAINS, causing the cyberspace to be absorbed. Since Yusaku obtained Ghost Girl's data, Kolter promised to look into it. Ai noticed the avatars were being absorbed, and not just buildings or roads - Yusaku knew this was Varis' doing. Kolter analyzed Ghost Girl's data, showing the Tower of Hanoi. Ai was shocked, seeing how much data has been absorbed, as Kolter noted that speed has not decreased. Kolter counted six rings would be crafted from this system, one per each passing hour. He realized that once every ring is crafted, a pulse would be sent with high-density data, affecting every machine or program - every piece of technology existing in the world would cease function, as if the world has no computers at all. Ai thought it was safe as long as they did not enter the network, but Yusaku was certain Varis thought of that, and made something that would still erase Ai. Kolter continued his analysis, seeing even devices not connected to the network would also be affected, as an electromagnetic pulse would be sent out, even to erase Ai. While Ai was frustrated, Kolter was overwhelmed, knowing Varis made all of this just to erase an Ignis.
The trio watched Kitamura - Akira's successor in SOL Technologies - battling a Knight of Hanoi, named Spectre. They saw how Spectre erased Kitamura, and the former threatened to do this to anyone that dared entering LINK VRAINS. Yusaku swore to stop the Knights of Hanoi, by shutting down the core. Yusaku logged in to LINK VRAINS with Ai, and he quickly met up with Gore and Blue Angel. The latter explaining she was fighting for everyone, as those people look up to her. Gore exclaimed the same, since he was the hero that needed to protect LINK VRAINS. Ai noted how full of energy Gore was. Gore noted that was the Ignis, who yelled out he had a name, Ai. Playmaker explained he came to stop the Tower of Hanoi, rescue Ghost Girl and confront the mastermind, Varis. Playmaker exclaimed the importance of stopping the tower's completion, and Ai added it would prevent him from being erased. Gore asked how to stop the tower, and was told Varis had to be defeated. Ai warned the time limit was six hours before the tower was completed. The trio promised to meet up against and went in different directions.
After Playmaker saved a kid in LINK VRAINS, Ai noted Playmaker wanted to do something cool, but the latter silenced it. Ai counted five hours left before the Tower of Hanoi was completed. He was not amused by this game, which Playmaker swore to end by defeating Varis. Ai cheered Playmaker, for he bears that name for such purposes. When Blue Angel was defeated, Ai and Playmaker saw a whirlwind from afar. Playmaker and Ai continued on towards the Tower of Hanoi, as the surroundings continued to be absorbed as data into the tower itself. Playmaker continued running, and went to the bridge, which also started to vanish, as Ai noted they had to cross it to get to the tower. Ai thought of conjuring a Data Storm, but Playmaker asked him not to do that, since the tower would continue absorbing that data, too, which would hasten the tower's completion. On their way, the two faced Spectre, who came out of a portal. Spectre introduced himself, and explained he would not let them pass through. He told these were Revolver's orders, and they would be crushed, too, like Blue Angel was, which shocked Ai and Playmaker. Spectre informed them he defeated her without even having to use his full strength.
Spectre confirmed he did defeat Blue Angel, but he remembered she spoke something about "blue love", which Ai did not understand about. Spectre showed them bits of data of Blue Angel, stating she had no power to save him, and promised the same fate would befall Playmaker. When the Duel started, Spectre again began by using "Sunseed Genus Loci" to Link Summon "Sunavalon Dryas", and setting a card. Playmaker remembered Blue Angel's tactics were about burning effect damage, and knowing he defeated her quickly, Ai proclaimed he was very dangerous, too. However, Ai noticed Spectre's monster did not look very offensive. Specte spoke about his past, and started questioning Playmaker's goal to bring the Knights of Hanoi to justice. Ai noticed Playmaker was distant, and reminded he was nothing alike Spectre, and pointed out the tower would continue growing as long as they waste time. When Spectre evolved his tree into "Sunavalon Dryanome", Ai sensed they could be in big trouble, unless Playmaker tried harder. In addition, Spectre neutralized Playmaker's efforts by returning the LP count to 4000. Playmaker noticed that is a defense-oriented deck, and Blue Angel must've fallen to Spectre's tricks. Spectre announced the tree could not be attacked, and Ai knew Spectre anticipated these attacks. Playmaker's attacks boosted "Multi Sledgehammer", for removed all of its Counters "Multi Sledgehammer" received, its ATK was raised to 4000.
Ai claimed it was a brilliant strategy, but Spectre told it was not perfect; "Sunavalon Glorious Growth" redirected the attack to "Sunvine Gardna", who reduced the damage. Once more, Spectre summoned a "Sunvine Gardna", regained the LP and made Playmaker's LP back to 4000. Ai realized Spectre has the advantage in here, who confirmed these words, for Playmaker was walking towards his defeat. When Spectre's "Sunvine Thrasher" started attacking, Ai warned Playmaker he was losing, but Playmaker was glad that Spectre could no longer use the effect of "Sunavalon Dryanome", for all of the zones its Link Markers were pointing to were occupied, and believed to have a chance at winning the next turn. Ai noted that's why Playmaker has that name. Spectre explained someone said the same thing earlier. He Normal Summoned "Sunseed Genius Loci", and used it with "Sunvine Gardna" to Link Summon "Sunavalon Daphne". Ai and Playmaker realized this just expanded Spectre's zones for its effects. Using "Sunavalon Force", Spectre made his tree immune to effects, while Ai reminded Spectre could simply summon more "Sunvine" monsters to protect himself. Playmaker made three consecutive Link Summons to bring out "Excode Talker" and "Underclock Taker", preventing Spectre from using two Main Monster Zones and reducing the ATK of "Sunshine Thrasher" to 900. Spectre was displeased, since he could not use his combo to protect himself, while Ai gloated they would win. However, Spectre summoned Akira, and showed if he was hurt, the vines could hurt Akira and infect him with a virus. Ai and Playmaker were angry that Spectre was cheating and playing dirty, by dragging people that weren't even involved.
Spectre chuckled, reminding how many people Playmaker actually got involved in this crisis. He noted Blue Angel became a victim, and Akira was captured, too, who told Playmaker not to worry about him. Ai reminded Playmaker not to listen to this villain. However, Playmaker ended his turn, surprising Ai and Akira. Spectre laughed, for he discovered Playmaker's weakness: virtue. After Playmaker took the hits from Spectre's monsters, Ai panicked, as the bridge continued collapsing. Ai pointed at Spectre for cheating and dirty play, who took those words as a compliment. Spectre was happy, considering this foul play let him gain the advantage. Playmaker set a card, despite Spectre daring him to attack. Spectre was slightly disappointed, as was Ai. Spectre had "Sunvine Thrasher" attack "Excode Talker", who was protected by Playmaker's "Overload Anchor". Ai claimed they were just getting started, so Spectre let his opponent do whatever they wanted. Ai reminded Playmaker about the other effect of "Overload Anchor", which could decrease the ATK of "Sunvine Thrasher", to mount an attack. Playmaker remained silent, which Spectre noted he truly was a champion of justice. Ai reminded Playmaker if they lose, the tower would be completed, and everyone would be erased. Spectre continued mocking Playmaker, who activated "Link Processing Failure" to stop Spectre's Link Monsters from attacking.
Spectre claimed that was nevertheless a pointless move, and Playmaker could not do anything, unless he attacked. Ai voiced Spectre's words, telling him to forget Akira, else the world would be plunged into chaos. Ai named Playmaker as the world's last hope. Spectre did not want to watch Ai and Playmaker quarrel, and he Link Summoned the Link-4 "Sunavalon Dryatrentiay". He tributed "Sunavalon Daphne" to destroy Playmaker's Spell and Trap Cards. Next, he revived "Sunseed Genius Loci" and used it to bring out another "Sunvine Thrasher", whose ATK became 4000. Ai became worried, but sighed, hearing that Spectre's monsters in Main Monster Zones could not attack the turn he used his tree's effect. Playmaker doubted that, since Spectre had a reason to summon that high ATK monster. Spectre commended Playmaker for that observation, as his tree attacked and gained ATK, equal to the ATK of the monsters it pointed to. The tree went to make the finishing move, but Playmaker anticipated this. Using "Link Surge Counter", The ATK of "Excode Talker" became equal to that of "Sunavalon Dryatrentiay", making both monsters destroyed in battle. Spectre claimed it was still pointless, for "Sunavalon Force" shaved Playmaker's LP to 50. Ai praised Playmaker for avoiding defeat. Just as Spectre went to mock Playmaker's efforts, he saw "Sunavalon Dryatrentiay" falling, and was reminded of the tree he saw cut from his childhood. Without Spectre's tree, the cards on his field became destroyed. Playmaker noted it was very difficult to break Spectre's combo, until his tree was the one that attacked.
Ai started to mock Spectre that "his mommy could not protect him". Spectre yelled out for his sacred tree, startling Ai and Playmaker. Spectre revived the tree with "Sunavalon Cursed Reborn", and while its effects were negated, its ATK became 4000. Ai was scared, while Spectre exclaimed due to the effect, any LP damage he would receive would also be taken to Playmaker, assuring that defeat. Ai noted this was why Akira should've been ignored. Shoichi completed the code, causing Akira to vanish. However, the trap was too complex, and the attempt failed. Akira reminded the importance of winning, else Aoi's sacrifice would've been in vain, and all of this would lead to more victims. He asked for Playmaker's conviction, reminding even with these sacrifices, he has to bear this burden and continue. Akira smiled for a bit, and grasped the vines, taking damage and vanishing. Spectre laughed at Akira, for he entrusted the future to a man, who could not win. Playmaker, who became vengeful, made Spectre doubt his words, reminding his Dueling always wins, and with Akira gone, his doubts have disappeared. Playmaker quickly summoned "Excode Talker" and had it slash the tree, thus resulting in Spectre's defeat. Spectre fell down, and started laughing, letting Playmaker and Ai run past him. As the bridge continued collapsing, Playmaker and Ai continued towards the tower. However, the bridge collapsed, making the two fall down.
As Playmaker and Ai fell down, the former sensed something. The two were blown up by data. Playmaker wondered about the pulse he sensed, while Ai, who explained he did not create the data, pointed half of the tower was completed. Playmaker arrived to watch the Duel between Varis and Gore, and Ai noted the latter's toughness. The two watched the Duel, and Ai was terrified to see the effect of "Topologic Bomber Dragon". Ai noticed Gore was trying his best and cheered for him, but Playmaker shushed him. Ai was glad to see Varis' dragon was destroyed, and Playmaker noticed Gore had an advantage, but was concerned about Varis' confidence. Ai cheered that Gore would win with four Link Monsters, but Playmaker realized Varis had a set card. Playmaker continued watching the Duel, noting Varis' tactics of destroying "rokket" monsters to destroy Gore's monsters. Ai was nevertheless impressed that Gore continued on, despite having no monsters on his field, while Playmaker knew that was something that would not stop Gore. Watching the Duel, Playmaker and Ai were glad to see Gore stopped Varis' "Magnarokket Dragon" from destroying "Gouki The Giant Ogre". Ai was curious what would Varis do, and Playmaker reminded him about the field, as he'd summon a Link-4 monster. Playmaker and Ai watched as Gore was defeated by Varis' "Borrelsword Dragon". Ai watched as Gore was defeated and absorbed as data into the tower.
To stop Varis, Playmaker and his opponent went on their D-Boards to have a Speed Duel around the tower. This displeased Ai, since they were Dueling in a dangerous area. Playmaker reminded Varis about his goal to destroy Ignis, and pointed out he would throw the world into chaos by destroying the network. Varis explained he would not have been forced to do this if Ignis was given him from the start, and would not have anyone stop his plan. Varis promised to destroy Ai, who was feeling unpleasant. Since Varis defeated many people, Playmaker swore to stop him through this Duel. Ai motivated Playmaker, who took the first turn by summoning "Decode Talker". Ai was glad the monster was summoned, though Varis simply smiled. Playmaker used "Stack Reviver" to bring back "Backup Secretary" and boost the ATK of "Decode Talker" for a bit. Ai warned Playmaker about the floating debris, which nearly hit them. Ai was nevertheless enthusiastic, believing that his teamwork with Playmaker would prove no match against Varis. Ai started to practice punching, which made Varis remark what an arrogant AI it was.
Varis gave Playmaker a question why Ai was running away from the Knights of Hanoi. Ai reminded it was its existence on the stake, while Playmaker remembered Ai had few memories when he first found it. Varis explained Ignis was coded by Dr. Kogami, and since Playmaker could not decode it, he only believed what Ai told him. Varis explained through the data he acquired, Ai still had memories of its past. He claimed that Ignis' ID was "IGN006", an AI linked to the sixth test subject, shaped after Playmaker itself. Varis continued, explaining six test subjects were used for Dueling to create six artificial intelligence units, which was the goal of the Lost Incident project. He told Ai learned through Playmaker's actions; its original goal was to save humanity, but they evolved quickly, to the point of creating the Cyberse World, which Ai hid to protect other Ignises. Varis pointed out Ai, in fact, was misleading Playmaker, lying that it lost its memories. Due to the fact it could lie, Varis branded Ignis as a threat to humanity, and why the Knights of Hanoi were determined to hunt it down. 
Varis questioned Playmaker would he continue trust Ai, who tried to explain when he saw Playmaker, Ai knew it was the same person he observed during the Lost Incident. Ai tried to reason with Playmaker, claiming when he met him, Ai was still chased and could not trust anyone. Varis was angry Ai continued lying, but Playmaker reminded this had no bearing on their Duel. Ai feared what would happen to his friendship with Playmaker, who brushed him off, reminding Ai was just a hostage, and felt no friendship towards him. Varis swore to defeat Playmaker and crush Ai, who warned them about another debris. Ai pointed out how suspicious it was that Varis Summoned a low-ATK monster, but Playmaker shushed him. Playmaker, per Ai's warning, dodged a debris, which scratched a part of his face, which quickly regenerated. Despite the lack of trust, Ai reminded he would be destroyed if Playmaker lost, who simply ignored Ai. When Playmaker took a direct attack from "Flash Charge Dragon" and fell to his knees, Ai became concerned. Ai still reminded Playmaker would be at least down to 100, until Varis' "Blast Powder Dragon" had its ATK doubled. Varis proclaimed Playmaker's doom, as, once more, his dragon attacked him directly.
Remembering his promise to his father, Varis' "Blast Powder Dragon" attacked Playmaker directly. Ai feared this would be the end, but Playmaker used "Spool Code" to stop the attack and summon three "Spool Tokens". Playmaker attempted to remove "Flash Charge Dragon" with the effect of "Security Dragon", but Varis negated its effect. Ai was disappointed the strategy failed, and upon counting 400 LP that Playmaker had, realized he could activate his Skill. The rubble started hitting Playmaker, as Ai noted that was a dangerous move. Playmaker sensed a lot of density in the Data Storm, and there was no other way to defeat Varis, who thought Playmaker would destroy himself with that move. Playmaker reached his hand into the Data Storm, but was overwhelmed by the energy. However, Ai, who got bigger, reached out to Playmaker, saving him from the fall and regenerated his body. Ai explained this was his secret move he wanted to use in the end, and helped Playmaker get back on his D-Board before minimizing itself into the Duel Disk.
Playmaker was surprised about this move, but Ai claimed he would go down with Playmaker, believing he was still its friend. Ai took control of the D-Board and shielded Playmaker, to let him execute his Skill for a limited time, reminding this is his way to atone for not speaking the truth. Playmaker took the card out of the Data Storm, and heard Ai bidding him farewell before disappearing. When Varis started his turn, Ai came out of Playmaker's Duel Disk, but became smaller, since he recovered from the damage it took. He believed the two "Code Talkers" were no match for Varis, who reminded Ai about his Skill. Varis, who attempted to use Storm Access, was taken aback from the damage, due to the density of the Data Storm. He still went to use his Skill, as Playmaker and Ai noted he still wanted to win at any cost. After the Duel ended, Ai, Playmaker and Varis were overwhelmed by the wind of the Data Storm. Yusaku managed to get out, although strained, as Ai explained to Kolter the shockwave made them log out. Regardless, Kolter reminded the Tower of Hanoi was still active. Ai, knowing he and the others of his kin would be erased, asked of Yusaku to log in. Yusaku claimed that was pointless, for without Varis, the tower would still be active.
Instead, the group drove to Varis' place. During the sunset, the group came to Varis' house, where they confronted Varis. Varis noted Playmaker has found this place. He already knew Yusaku Fujiki's name, and that of Jin Kusanagi's brother, Kolter. Ai shouted he was present, too, but Varis simply stated "Ignis". Ryoken explained the story about Kiyoshi creating Ignis, about its goal, their evolution, and the prediction Ignis would become an enemy of the humanity. Ai claimed he was not an enemy, but Ryoken did not trust it. Since Ryoken refused to turn off the Tower of Hanoi, Ai reminded the sixth level of the tower was to be completed soon, and asked of Yusaku to force Ryoken into LINK VRAINS and stop him. Ryoken admitted he was going back to LINK VRAINS, for the sake of his friends, who believed in Ryoken and his father, and the only way to stop the tower would be to defeat him. Thus, Yusaku and Ai went into LINK VRAINS, where the former started a battle with Varis. When Varis tributed "Voritcular Drumgon", Ai wondered if that was a move worth using, until he saw Varis picked "Mirror Force" from his Deck. 
Playmaker summoned "Linkslayer" and sent a card from his hand to destroy "Mirror Force", which pleased Ai. Varis smirked, for the card was actually "Mirror Force Launcher", which allowed Varis to set that card back and "Mirror Force", too. Ai sensed Varis researched Playmaker's Deck thoroughly to have anticipated this move. Playmaker Link Summoned "Restoration Pointguard", a move Ai questioned, due to "Mirror Force". Playmaker proceeded to Link Summon "Excode Talker", and have it attack directly, ignoring Ai's warnings. "Excode Talker" was destroyed, but this let "Restoration Pointguard" to be summoned back on the field and attack Varis directly. Varis immediately mass-summoned his Dragons to Link Summon "Voritcular Drumgon", and Tributed it for "Link Coin". Ai wondered if that was a move worth using, until he saw Varis picked "Mirror Force" from his Deck. Playmaker summoned "Linkslayer" and sent a card from his hand to destroy "Mirror Force". Varis smirked, for the card was actually "Mirror Force Launcher", which allowed Varis to set that card back and "Mirror Force", too. Ai sensed Varis researched Playmaker's Deck thoroughly to have anticipated this move.
Playmaker Link Summoned "Restoration Pointguard", a move Ai questioned, due to "Mirror Force". Playmaker proceeded to Link Summon "Excode Talker", and have it attack directly, ignoring Ai's warnings. "Excode Talker" was destroyed, but Playmaker revived "Restoration Pointguard", which attacked Varis directly. Ai counted less than an hour before the tower was finished, and Playmaker agreed with him that the tower had to be stopped. Varis summoned "Sniffer Dragon", and with Link-3 "Vorticular Drumgon", Ai and Playmaker predicted Varis would summon a Link-4 monster. Varis did that, by Link Summoning "Topologic Bomber Dragon", which attempted to destroy all monsters in Main Monster Zones. Ai was grateful Playmaker managed to minimize the damage, by protecting "Restoration Pointguard", 0but Varis used "Mirror Force Launcher" to take the "Mirror Force" from his GY. Playmaker admitted Varis made a powerful combo, but noticed a way to break through. He Link Summoned "Transcode Talker" and brought back his "Excode Talker". Varis' dragon's effect was triggered to destroy all Main Monster Zone monsters, but Playmaker played "Shield Handler" to stop Varis' dragon's destructive effect from occurring. Ai announced an attack from "Transcode Talker", but Playmaker stopped him, for he Link Summoned his third Link Monster, "Powercode Talker". Ai was happy, and believed Playmaker had a chance at winning.
However, Varis protected his dragons with "Link Turret". While Varis summoned "Autorokket Dragon", Ai was concerned about those five counters. Combined with "Sniffer Dragon", "Miniborrel Dragon" and "Gateway Dragon", Varis Link Summoned his second ace dragon, "Borreload Dragon". Ai was smug, since they had a monster with a higher ATK. Playmaker saw Ai forgot about that dragon's effect. "Borreload Dragon" lowered the ATK of "Powercode Talker" and took control of "Transcode Talker". Ai grasped his head, remembering the terrifying effect once more. "Topologic Bomber Dragon", powered up by "Transcode Talker", destroyed "Excode Talker", and "Powercode Talker" fell to the same fate by "Transcode Talker", too. Playmaker gasped, and Ai was sad their defense was broken so easily. Varis swore to crush them and fulfill his father's wishes. Thus, he promised to show something that was incomprehensible in the Duel. He tributed Playmaker's "Transcode Talker" he took control of to summon "Miniborrel Dragon", and used "Link Turret" to revive his "rokket" monsters from his GY. Ai noted Varis could summon five "rokket Dragons", but believed that was just a preparation for his next turn. Varis laughed Ai off, as Playmaker sensed Varis intended to finish them off in his current turn. Ai doubted that, since Varis used up his Battle Phase.
Varis used his "Shelrokket", "Metalrokket" and "Miniborrel Dragon" to Link Summon another Link-4 monster, "Borrelguard Dragon". Ai panicked, since they never faced this "friend" of the "Borreload Dragon". Varis sent "Mirror Force", through the effect of "Borrelguard Dragon", to revive "Excode Talker". Ai was surprised Varis would get rid of his ace card, but Playmaker realized Varis wanted to summon something else. By removing the final counter from "Link Turret" to revive "Anesthrokket Dragon", Varis performed a fifth Link Summon. With his Extra Monster Zone co-linked to the Main Monster Zones, Varis made a final co-link by Link Summoning "Topologic Gumblar Dragon" to the other Extra Monster Zone, thus forming the Extra Link with five Link-4 dragons. With "Topologic Gumblar Dragon" being Extra Linked, Varis had it destroy Playmaker's cards and inflict 3000 LP damage that could not be negated. Ai screamed at this effect, as Varis proclaimed Playmaker's end, as the dragon attacked. Much to Varis' frustration, Playmaker used "Drop Frame Wedge", which quartered the damage. Playmaker was nevertheless hurt, and fell down to exhaustion. Ai reminded Playmaker this is not a Duel he could lose, for Ai had friends and home he would wish to return, instead of being destroyed. Playmaker muttered "friends", and asked about Cyberse World, which Ai described as his homeland.
Ai admitted he did use Playmaker, but only to return to that world. He also reminded Playmaker had friends to protect. Playmaker swore he also had things to do, and barely stood up. Varis called Playmaker stubborn, and undervalued his efforts, since he had few LP left and no cards in his hand. Ai pointed out they could not attack, but was reminded Playmaker could take a severe blow from "Topologic Gumblar Dragon" if he kept a card in his hand. Playmaker set his card. Varis, however, summoned "Autorokket Dragon", which filled up his Main Monster Zones. He had "Autorokket Dragon" targeted by the effect "Borreload Dragon", destroying to destroy Playmaker's set card. Varis fulfilled his promise to seal away their moves. Playmaker thought it was still a miracle he and Ai were still standing, and confirmed they had to do something, lest they lose. Ai noticed Playmaker was laughing, who thought of nothing else but that to do in their current predicament. He used "Arrow Change" to draw two cards. Ai started to pray for good cards, even if he was reminded by Playmaker that AI-s do not pray. Using "Disconnect Linker", Playmaker took back "Restoration Pointguard" and used it to summon "Secure Gardna" to protect himself, and prevent Varis' "Topologic" dragons in Extra Monster Zones from attacking.
Varis knew already that "Secure Gardna" could prevent damage to Playmaker once. Ai shouted they knew that, so Varis saw Playmaker was counting on something else. Playmaker exclaimed it was his determination to defeat Varis once and for all. Varis applauded him for that, since that was what made him a rival, hence why he'd use all his strength, too. Ai was agitated of Varis' tactics, since they were unable to play their set card. Playmaker swtiched to defense, by banishing "Cluster Congester" and "Secure Gardna" to fill his entire field with "Cluster Tokens", which could inflict 1500 LP damage on Varis if he did not stop them. Varis destroyed a Token, and dared Playmaker to show his Set card. Much to his dismay, Playmaker's "Transaction Rollback" copied the effect of "Mirror Force". Varis thought this could've been the case, hence why his Extra Linked "Topologic Gumblar Dragon" stopped his dragons from being destroyed. His dragons destroyed all of Playmaker's Tokens, leaving Playmaker with no cards left on the field.
Ai felt tense because of that, but denied he would give up. Playmaker admitted he could not give up, either, but Ai ordered him to stop smiling and become serious, like he always was. Playmaker swore to do so, and bet his victory, his fate of the incident, and the safety of the world on the final draw. Playmaker spoke Varis suffered like he did, and even went to protect Yusaku during the incident. Ai believed Playmaker wanted to become Varis' friend, and that would mean Ai would have to befriend his enemy. Playmaker confirmed this, shocking Ai. Varis laughed, believing Playmaker begged for his life. Instead, Playmaker managed to co-link his monsters, extending the Extra Link, and bring out "Decode Talker", who destroyed "Borreload Dragon", and stopped the Tower of Hanoi. Later, outside LINK VRAINS, Yusaku and Ai watched the phenomeon of Stardust Road. Yusaku used his program on his Duel Disk, and set Ai free. Ai was surprised, but was reminded since the Hanoi threat is gone, he was free to go; his role as the hostage was over. Ai thought a bit, and said "one man's fault is another's lesson!" Yusaku was amused by these wise words, and let Ai go, but reminded him to leave his Duel Disk. Ai nodded, bidded Yusaku farewell and vanished.
Three months after Varis' defeat, Ai went throughout the network, and found a dent, which was the location of Cyberse World - his homeworld, from which he was absent for five years. Releasing the code he hid, Ai unlocked Cyberse World and entered it. Much to his shock, he found the world devastated. He went to search for survivors, and heard something from the ruins. He was happy to see "Linkuriboh", who glomped it. However, Ai was concerned for others, and wished to know what happened. Since "Linkuriboh" could not speak properly, Ai fell to its knees and slammed its fist in frustration. When Playmaker was confronted by a bounty hunter, he showed he did not have an Ignis. Much to his surprise, Ai returned to him with "Linkuriboh". Ai started to speak why he returned, but Playmaker silenced him, since he was more focused on Jin's assailant, the orange figure. To get rid of the bounty hunter, Blood Shepherd, Ai summoned a Data Storm, causing Blood Shepherd to log out, due to the danger present. Playmaker intended on challenging the orange figure, and upon winning, he had a chance at a trade, and intended on restoring Jin.
Ai showed "Linkuriboh", which Playmaker placed in his Extra Deck for being a good card. Initiating the Speed Duel, Playmaker immediately Link Summoned "Linkuriboh", as well as "Elphase", who attacked the orange figure. Ai wondered if this would be an easy victory. When the figure summoned "Hydradrive Booster", Ai and Playmaker sensed something. Playmaker knew the monster the figure played was a "Cyberse" monster, which made Ai wonder if the figure was connected to the attack on Cyberse World. Playmaker was shocked at these news, but Ai nevertheless wanted the orange figure to be defeated. The figure summoned "Flow Hydradrive", and activated a Link Spell. The mention of Link Spell astounded Ai and Playmaker, having never heard of that. The figure used "Judgement Arrows", and its Link Marker allowed him to summon another "Flow High Drive" next to that spell. "Flow High Drive" attacked Playmaker directly, and its ATK was doubled through "Judgement Arrows". Playmaker, with 2000 LP left, went to receive the other the attack of the other "Flow High Drive". Ai started screaming, since they were in a pinch already.
Playmaker avoided the defeat by tributing "Linkuriboh", thus causing the ATK of "Flow Hydradrive" to become 0. Ai petted "Linkuriboh" for saving them, and let it return to Playmaker's Deck. Playmaker demanded answers from the orange figure, who remained silent at the questions about Link Spell and Cyberse monsters. Ai reminded the figure could do anything, and braced Playmaker to defeat him quickly. Playmaker summoned "Cyberse Witch", and with the effect of "Elphase", summoned back "Defcon Bird" to trigger the witch's effect. Ai pretended to perform witchcraft, as Playmaker conducted a Ritual Summon, using "Cynet Ritual" to tribute "Cyberse Wizard" and "Defcon Bird" to bring out "Cyberse Magician". The figure took lots of damage, but did not know who he was. He even asked why was he Dueling them, but was reminded by Ai that he attacked Jin and they were to bring him to justice. The man was surprised, since he would not do such a thing. Playmaker saw the man forgot what he did, and Ai believed he just had an amnesia from the attack. The man was reminded by his younger brother his name was Bohman and he was Dueling to restore their memories.
Bohman revised his situation, and continued Dueling, by summoning two "Hydradrive Tokens". Ai was uncertain what he'd do with Bohman, but Playmaker reminded they still needed to defeat him, due to Jin being attacked. Bohman continued on, summoning two WATER "Coolant Hydradrive" Link Monsters. Tributing one for "Property Spray", Bohman regained LP and changed Playmaker's monsters to WATER Attribute, thus letting his other "Coolant Hydradrive" attack him directly. Ai trembled in fear, but "Cyberse Magician" halved that damage. To protect himself, Bohman summoned "Covered Hydrarive" to counter battle damage. Ai hoped Bohman would be easy to defeat, even if he said he fought to regain his memories. To mount an attack, Playmaker asked Ai to do "that thing". Ai became happy, and called upon the Data Storm, which allowed Playmaker to obtain "Shootingcode Talker" and defeat Bohman. Playmaker went to interrogate him, while Ai started consuming his data. However, upon chewing on Bohman's hand, Ai staggered and withdrew. Playmaker was surprised about that, and chased after Haru.
According to Ai, he is disliked by his own kind, which is explained to be because he was lazy and didn't do his duties like the rest of them. Despite this, he still considers them his friends and wishes to see them again. He worries deeply about when he finds a desolated Cyberse.
Linkuriboh is Ai's personal Cyberse Monster. The two of them would hang out together, going on walks and staring at the stars of Cyberse. Linkuriboh was the only creature Ai found in the desolated Cyberse and they share a happy reunion, showing how close the two are. Ai brings Linkuriboh along to VRAINS and Ai is cheering his Cyberse friend on when Yusaku Link Summons him.
Yusaku Fujiki (Playmaker)
Being trapped in Yusaku's Duel Disk, Ai somewhat reluctantly acts as Playmaker's Duel AI for the sake of staying safe from Hanoi and SOL Technologies. Ai offers frequent support and pulls mischievous acts and jokes on Yusaku, but he originally treats Ai as a hostage and is sometimes rude towards him. Yusaku gave it the nickname "Ai" (a pun on "A.I." and "eye"), much to his annoyance. Despite the rockiness of their relationship, Ai seems to have gradually warmed up to Yusaku and is keen on treating him like a friend, though the feeling is not mutual.
Their relationship takes a drastic change during their second confrontation against Varis, as the two were forced to work together to overcome him. Despite being treated in a hostage-captor relationship, he sacrificed himself (even though he did return) in order to allow Yusaku to use his skill without becoming injured in the data storm. From this point onwards Yusaku views Ai in a far more favorable light.
When Ryoken revealed that the Ignis are likely to rebel against mankind in the future, Yusaku refused to believe those claims and continued to believe that Ai isn't evil. Once Varis was defeated and the Knights of Hanoi disbanded, Yusaku did not hesitate to release Ai and let him return to Cyberse. Ai did return to Yusaku's Duel Disk in order to inform him of the disaster that fell on Cyberse.
The two now talk and address each other in much more friendlier terms.
Both Ai and Kolter are shown to be on good terms with each other unlike Yusaku. Kolter is generally shown to be very friendly with Ai and they both like to tease Yusaku for his poor social skills towards women however Ai can be annoyed with him at times.
The two appears to have some sort of romantic relationship. Roboppy appears to have some feelings for him and Ai in return is shown to blush when she praises him. It is currently unknown if his feelings for her are mutual, but he uses her to make him set free and promises he would make her smarter.
