"The Light Shining in Eternal Darkness" is the one hundred and thirty-first episode of the Yu-Gi-Oh! ARC-V anime. It first aired in Japan on November 13th, 2016. It became available with official subtitles via Crunchyroll on November 28, 2017.
As the time of the revival draws near, Riley stands in Declan's way, trying to convey Ray's feelings! In order to prevent Leo's ambitions, an impatient Declan launches a fierce attack with his "D/D" monsters right away, but Riley's surprising strategy overpowers him...!
Turn 3: Declan
During his Standby Phase, the effect of "Eternal Darkness" inflicts 1000 damage to Declan (Declan 4000 → 3000). "Darius" attacks "Film Magician". As "Film Magician" was attacked, its effect activates, making its ATK/DEF equal to the ATK of "Darius" during damage calculation only, while its other effect prevents "Film Magician" from being destroyed by battle. Since "Darius" would be destroyed by battle, Declan activates its effect, detaching an Overlay Unit to prevent its destruction, destroy the monster it battled, and inflict 500 damage to Riley (Riley 4000 → 3500). "Alexander" attacks Riley directly (Riley 3500 → 1000). Riley obtains an Action Card. "Genghis" attacks Riley directly, but Riley activates the Action Card "Damage Banish", reducing the battle damage to zero.
Turn 4: Riley
Riley draws "Pure Ray". He activates his face-down "Photo Frame", which lets him copy the name and effects of a face-up Spell/Trap his opponent controls. He targets "Eternal Darkness". Riley activates "Pure Ray", which lets him destroy a card on both players' fields with the same name and decrease the ATK of all monsters on the field by 100 for each monster on the field. He destroys Declan's "Dark Contract with the Eternal Darkness" and his own "Photo Frame", treated as "Dark Contract with the Eternal Darkness" ("Alexander": ATK 2500 → 2200) ("Darius": ATK 1900 → 1600) ("Genghis": ATK 2000 → 1700). Riley Normal Summons "C/C Critical Eye" and activates "Montage Fusion". This allows Riley to use monsters he controls as to Fusion Summon a monster while both players have Fusion Materials listed on a Fusion Monster. He fuses "Critical Eye" and "Montage Fusion" to Fusion Summon "C/C/C Sonic Halberd of Battle" (3000/0). It can attack twice during the same Battle Phase, but since Declan controls a WIND monster, "Sonic Halberd" can attack three times. "Sonic Halberd" attacks and destroys "Alexander" (Declan 3000 → 2200) and "Genghis" (Declan 2200 → 900). As "Genghis" was destroyed, its effect activates, allowing Declan to add a "Dark Contract" card from his Graveyard to his hand. He adds "Eternal Darkness". "Sonic Halberd" attacks "Darius".
Turn 7: Yugo
"Crystal Wing" attacks and destroys "Greedy Venom", with "Crystal Wing" gaining ATK equal to the ATK of the Level 10 "Greedy Venom" during damage calculation only ("Crystal Wing": 3000 → 6300) (Yuri 4000 → 1000). As "Greedy Venom" was destroyed, Yuri activates its effect, destroying all monsters on the field, and inflicting damage to their controllers equal to those monsters' original ATK. "Crystal Wing" is destroyed (Yugo 4000 → 1000). As "Greedy Venom" was destroyed, Yuri activates the effect of "Starving Venom Fusion Dragon", granted by "Greedy Venom", in his Graveyard, banishing itself to Special Summon "Greedy Venom" again. As an Extra Deck monster was destroyed, Yugo activates his face-down "Extra Shave Reborn" to Special Summon an Extra Deck monster with a lower Level than the destroyed monster from the Graveyard. Yugo Special Summons "Clear Wing Synchro Dragon".
As a monster was Special Summoned to his field, Yugo Special Summons "Speedroid Rubberband Plane" from his hand via its own effect, and activates its effect, which would decrease the ATK of an opponent's monster by 600. As a Level 5 or higher monster on the field activated its effect, Yugo activates the effect of "Clear Wing" to negate that effect, destroy that monster, and increase the ATK of "Clear Wing" by that of the destroyed monster until the End Phase ("Clear Wing": ATK 2500 → 4300). "Clear Wing" attacks and destroys "Greedy Venom", but Yuri activates the effect of "Predaplant Drosophyllum Hydra" in his Graveyard, banishing a "Predaplant" monster from his Graveyard and returning another banished monster to his Graveyard to halve the battle damage he would take. He banishes "Predaplant Flytrap" from his Graveyard and returns the banished "Starving Venom" (Yuri 1000 → 500). "Greedy Venom" is destroyed. As a monster Special Summoned from his Extra Deck was destroyed Yuri activates his face-down "Extra Shave Reborn" to Special Summon an Extra Deck monster with a lower Level than the destroyed monster. He Special Summons "Starving Venom" (2800/2000) in Attack Position.
Turn 8: Yuri
Yuri activates the effect of "Starving Venom", negating the effects of a monster his opponent controls and granting its effects to "Starving Venom" until the End Phase. He negates the effects of "Clear Wing" and has "Starving Venom" gain its effects. Yuri activates "Predapruning", which lets him Special Summon a "Predaplant" monster from his Graveyard and equip itself to the Summoned monster. He Special Summons "Drosophyllum Hydra" (800/2300). Yuri activates the effect of "Drosophyllum Hydra" to banish a "Predaplant" monster from his Graveyard to decrease the ATK of an opponent's monster by 500. He banishes "Predaplant Moray Nepenthes" and targets "Clear Wing". As a Level 5 or higher monster activated its effect, Yuri activates the effect that "Starving Venom" inherited from "Clear Wing", negating that effect, destroying that monster, and increasing its ATK by the destroyed monster's ATK until the End Phase ("Starving Venom": 2800 → 3600). "Starving Venom" attacks and destroys "Clear Wing" (Yugo 1000 → 0).
