Blood Moon Falling

A werewolf samurai hunts beneath a blood moon while his human wife and two werewolf children wait at home. He returns to find vampire ninjas fleeing their house and his family murdered, then vows to destroy their clan. By day, in human form, he travels from village to village gathering the information needed for vengeance. His black-and-blue armor and moon-shaped forehead birthmark remain part of his identity in either form.
