Tougen Anki – Nikko Kegon Falls Arc (2026 Anime Series) - Season 1 (Episode 1 Added)

Season 1 (the Nikko Kegon Falls Arc, split into two cours: Oct 2026–Apr 2027) opens after the Kyoto and Nerima battles, with Rasetsu students stronger but fractured. Classmate Yaoroshi rejects headmaster Mudano’s lessons on friendship, drawn to Oni Brigade general Hayate Todoroki’s creed of “total eradication of the Momotaro.” When Shiki realizes the Brigade targets noncombatants, he, Mudano, and classmates pursue Yaoroshi to Nikko, where Kegon Falls has stopped flowing and a massive Momotaro research facility conducts horrific experiments on Oni captives. New instructors Hagure Nekosaki and Yu Innami join the training, while the Oni Brigade’s eight operatives and Momotaro’s Kegon Falls branch set the stage for ideological and physical warfare.
