The Wolfman, whose actual name is unknown, is the descendant of the Japanese wolves, a species that inherited both the blood of humans and wolves and went extinct roughly a hundred years ago. As a result, he can switch between the form of a wolf and a human, making him a werewolf. After his parents died during a young age, he moved in with relatives who knew nothing about his secrets. As soon as he was old enough to get a driver's license, he left for the city to find a job and live independent.
