A wave of unexplained killings in Kyoto has left the Shinsengumi hunting Rasetsu, warriors turned demonic by an elixir called ochimizu. Yukimura Chizuru, freshly arrived from Edo to find her missing father, stumbles onto the unit cutting one of the creatures down, and Vice Commander Hijikata Toshizo decides to keep her close rather than have her silenced. This four-volume manga adapts the Hakuouki otome game.
