Donten ni Warau Gaiden: Shukumei, Soutou no Fuuma

The second part in an anime film trilogy adaptation of the Donten ni Warau Gaiden spinoff manga.

The Fuuma ninja clan is a secret ninja tribe that seeks to welcome the “Orochi” when it resurrects every 300 years. In the clan we find twin brothers, Isuke and Isame, who live cursed lives after being persecuted by their tribe for being twins. This tragedy is only amplified as Isuke is faced with an impossible choice in the clan's twisted rite of passage.
