Emu Hino, a 29-year-old virgin, witnesses a mob hit and fears that the killer will now find her and kill her. Indeed, he sets out to do so; he's Yo Hinomura, a talented potter and artist who's been conscripted against his will to be the prime hitman for the 108 Dragons, a gang within the Chinese Mafia, who are determined to push aside Tokyo's local crime lords. He breaks into her house, and she asks that he make love to her before he kills her; she connects to his inner self, and he becomes her protector. Now he must defend her against the local crime gang, who have connections with corrupt Tokyo police. Will Yo and Emu make it out alive, and will the 108 Dragons triumph
