Tougen Anki – Nikko Kegon Falls Arc (2026 Anime Series)

In a world where “Oni” and “Momotaro” bloodlines have warred for millennia, teen Shiki Ichinose learns he carries Oni blood after a Momotaro assassin kills his adoptive father. Enrolled at Rasetsu Academy to master his powers, Shiki joins classmates battling Momotaro hunters while uncovering the ethics of a conflict built on dehumanization. The Nikko Kegon Falls Arc escalates this feud into a philosophically charged battleground: a dried-up waterfall, a hidden laboratory, and a radical Oni faction force Shiki to choose between vengeance and understanding, testing whether two interdependent lineages can coexist or must annihilate each other.
