Wolf Guy
Wolf Guy is a Japanese manga series of two volumes published in 1970 by Bunkasha. Originally written by Kazumasa Hirai and illustrated by Hisashi Sakaguchi (坂口尚), the series has been readapted with a more violent and mature setting in 2007 by Yoshiaki Tabata and Yuuki Yugo. This new adaptation, also known as Wolf Guy: Ōkami no Monshō, has been released as twelve volumes by Akita Shoten.
The main protagonist of the story is Akira Inugami, a Japanese-American exchange student. He is constantly bullied and abused by gang members (whom in the stories, he usually ends up killing or maiming). His parents were killed by hunters when he was young, mainly because of their werewolf lineage, and was raised by a pack of wolves he had befriended. He can transform into a werewolf in his own will. He is quite powerful during full moons and is weak only during the days of new moons.
