Yu-Gi-Oh! VRAINS episode 1: "My Name is Playmaker"
Their goal is to destroy the "AI World" known as "Cyberse" that exists somewhere in the depths of the Network.
The Knights of a Hanoi are an organization of hackers led by Revolver. The Knights all use a mostly white uniform with lines of differing colours in some parts of the uniform. On top of it, they wear a hooded white coat that covers their body and reaches the back of their knees. All Knights revealed so far are masked with the exception of Specter, while Revolver's uniform lacks a hood, showing that the higher ranks utilize styled clothings but keep overall similar aesthetics. The Knights of Hanoi utilize "Cracking Dragon" to assault the digital world with its power. Individuals who fall victim to this dragon while in Link VRAINS have their accounts deleted from the system.
Five years before the start of the series, Revolver assaulted "Cyberse" with "Cracking Dragon" with the intention to destroy it. The different Artificial Intelligences that protected it were restrained by Revolver and thus unable to stop the destruction of their world. However the AI Ignis appeared and forced a disconnection of the Cyberse World from the rest of the network, thus forcing Revolver out of Cyberse while keeping its location known only to him. However, Revolver, furious by Ignis' interference, ordered his "Cracking Dragon" to capture Ignis, which led to the AI to be dismembered by the monster's jaws. This made Revolver and the Knights of Hanoi spend the following years searching for Ignis' parts in order to find the location of Cyberse.
Five years later, the Knights of Hanoi continued their search of Ignis; but had many of their operations interrupted by the mysterious Duelist Playmaker, who defeated their agents, earning a name for himself. Specter, the Knights' second-in-command, informed Revolver that a trace of Ignis was detected and that SOL Technology was in pursuit. Knowing that if SOL retrieved Ignis, they would be able to restore Cyberse and ruin the Knights' efforts, forcing the Knights to act. Specter informed Revolver about Playmaker, who had interfered with them before. Revolver wondered if Playmaker was a member of SOL, but dismissed the possibility as they would act more publicly. Specter added that Playmaker erased every trace of his activity and eluded the Knights' searches, concluding that whoever he is he must be a skilled hacker. Revolver became interested in Playmaker, but decided to leave him for now as Ignis was their priority.
While SOL Technology performed a city scan in order to search for Ignis, the Knights of Hanoi decided to attack as the defenses of VRAINS would be left vulnerable at that point. Revolver ordered his men to search for Ignis, assaulting the digital world with their "Cracking Dragons" and ravaging the users in their way, deleting their accounts in the process. Ignis' remnants in the form of an eye was swiftly cornered by the Knights until Yusaku Fujiki and Shoichi Kusanagi used the lowered defenses to create an alternative path for Ignis, who used the newly made escape route, but ended up in Yusaku's Duel Disk as a result. Yusaku entered VRAINS using his persona Playmaker, saving the Charisma Duelist Blue Angel at the nick of time before she was deleted. Yusaku then confronted a Knight of Hanoi who told him that the AI they were looking for was on his Duel Disk and threatened to delete it if they did not cease their attack. Since Ignis was bonded to Yusaku's Duel Disk, the Knights must defeat Playmaker in a Duel in order to obtain it. Revolver, watching from afar, was amused at Playmaker while the Knights' agent accepted the challenge.
Ignis estimated that Yusaku's current Deck was not enough to defeat the Knight's "Cracking Dragon". He caused a Data Storm and instructed Yusaku to ride the wind and enter a Speed Duel. Ignis taught Yusaku the rules of Speed Duels. The Knight of Hanoi quickly Summoned his "Cracking Dragon", which he used for the remainder of the Duel, exploiting its abilities to avoid destruction and inflict effect damage, and further exacerbating his advantage through the Skill "Double Draw" which let him draw two cards during his Draw Phase. Ignis realized they must have hacked the system as the Skill was not known to him. Although Yusaku fared decently against the Knight of Hanoi, his LP was on critical state so Ignis instructed him to take a path where he was engulfed in a massive storm. Inside the tempest, Ignis told Yusaku that his LP was low enough to use the Skill "Storm Access" to gain a powerful monster. Yusaku did so and was able to acquire "Decode Talker" and Link Summon it. Through a combination of "Cyberse Wizard" and "Decode Talker", he was able to exploit the low DEF of "Cracking Dragon" and inflict piercing damage as a result of "Decode Talker" gaining ATK through its own effect, and due to being unable to be in Defense Position, it bypassed the Knight's "Pulse Bomb", defeating the Knight.
Regular Knights of Hanoi members use DARK Machine decks focused around Summoning "Cracking Dragon" and quickly dealing large amounts of effect damage. The cards are themed around hacking, malware, and other elements used to damage computers.
