Werewolf attends the Demon School (妖怪学校, Yōkai Gakkō), an institution where monsters master frightening humans. His hybrid form merges human and lupine characteristics, presenting as a canine-like man whose transformations intensify toward a more feral state during full moons. He dons a green jacket and possesses a rounded nose. In the anime adaptation, two fellow wolfmen appear: one distinguished by a yellow jacket and square nose, the other by a purple jacket and triangular nose.
