Sengoku Nights

Masayoshi Kurozuka is an ordinary high school boy… until the day he discovers that he is the reincarnation of an evil woman named Oni-hime, who sold her soul to the devil during Japan's warring period. Masayoshi must come to grips with his identity, all the while fighting off legions of ghosts – the remnants of men killed by Oni-hime. In order to free himself from this curse, Masayoshi must discover the truth behind Oni-hime's deal with the devil and clear her name in the eyes of the restless spirits seeking revenge.
