According to REMOW’s synopsis, Shiki and his Rasetsu Academy classmates continue gaining strength after surviving intense battles in Kyoto and Nerima. Yaoroshi, however, rejects Mudano’s teaching about the value of friendship.

Yaoroshi leaves the academy after embracing Oni Brigade General HAYATE Todoroki’s demand to wipe out every Momotaro. Shiki discovers that the brigade’s beliefs also mark noncombatants for slaughter, prompting him, Mudano, and the other students to pursue Yaoroshi.

They head to Nikko, where Kegon Falls stopped flowing some time earlier. A huge research facility now stands there, housing horrific experiments.

Tougen Anki first aired in July 2025, with its Nerima Arc starting in October 2025.
