Hakuouki

Chizuru Yukimura heads to Kyoto in search of her father, a doctor who has disappeared. However, she soon discovers that the city hides deadly creatures within its shadows, and that a fearsome group of swordsmen, the famed Shinsengumi, help maintain a tenuous peace. As both parties attempt to find the missing doctor, Chizuru and the men of the Shinsengumi will discover things about themselves that they would rather have left a mystery.
