His loyal underling, Kageyama, is shunned by the gang for his sensitive skin, making him unable to get tattooed. When assassins arrive, demanding Kamiura return to an international syndicate, he refuses and is killed. Before dying, Kamiura passes on his vampire powers to Kageyama, who seeks revenge against the syndicate's leader, Kaeru-kun.
