Kaidoumaru

During the Heian Period in Japan, a girl, disguised as a man, fights evil spirits alongside someone she cares for. Known as "Kaidomaru," she bears a Chinese character for "Flame" tattooed on her arm and is one of the "Four Devas." Her mission is to honor Raikou Minamotono, her lost love, who died defending Kyoto from a cursed "princess." The princess, once a childhood companion, is now Kaidomaru's greatest adversary, having been corrupted by a malicious ogre.
