Demon Slayer: Kimetsu no Yaiba Infinity Castle recap
Muzan survives Kagaya's trap and holds Tamayo captive, and the Demon Slayers are scattered through the Infinity Castle, his shifting dimensional fortress, fighting hordes of lesser demons. Kagaya's children map the castle with the Corps' crows. Shinobu Kocho finds Doma, Upper Rank Two, who killed her sister Kanae; Doma becomes immune to her poisons, kills her and absorbs her body, and Kanao arrives too late and takes up the fight. Zenitsu faces his former fellow student Kaigaku, who became a demon and the new Upper Rank Six, and kills him with a form of Thunder Breathing he created himself. Nezuko is given a cure made by Shinobu and Tamayo. Tanjiro and Giyu face Akaza, Upper Rank Three, who killed Rengoku.
Demon Slayer: Kimetsu no Yaiba Infinity Castle ending explained
Tanjiro beheads Akaza, but Akaza keeps fighting without his head. His memories return: as a human, Hakuji, he stole to buy medicine for his father, and later lost his fiancee Koyuki to poison before Muzan turned him. Akaza accepts defeat, stops regenerating and dies, reunited with Koyuki. Muzan holds Tamayo in his flesh and remains confident. This is the first of three Infinity Castle films.
