Tougen Anki: Nikko Kegon Falls Arc Part 2

Shiki Ichinose is an Oni-blooded kid in a modern Japan where the Oni and Momotaro bloodlines have been killing each other for generations, and nobody asked either side if they wanted in. Tougen Anki: Nikko Kegon no Taki-hen Part 2 picks up with that inherited war moving to the Kegon Falls area, where a sinister research facility turns a rescue mission into something messier. Shiki and the Rasetsu Academy crew get pulled into it alongside the Kikoku Unit, and the real friction isn't just the fighting. It's the argument over what the fighting is for: revenge at any cost, or refusing to become the thing you hate. Hayate Todoroki is back, and Momotaro-side threats like Hizumi Momotsugi and Director Kusabi keep the pressure on. If you liked Blue Exorcist for the supernatural school setup but wanted the moral stakes cranked harder, this is that. It's also got the bloodline-war tension of Demon Slayer and the faction politics and ugly-power arguments of Jujutsu Kaisen, with a darker infiltration vibe than a standard tournament arc. It's a 12-episode TV series, so you'll want part one first. Action-heavy, and it doesn't pretend the violence is clean.
