A magical wolf beast turned man, Garu lives his life out in the wilderness. Both pure and simple of heart, in order not to lose his ability to speak human language during his years in solitude, he started to have conversations with himself. Ultimately, in those wild and unforgiving conditions, he developed a second entirely different personality, Karu, who wants to conquer the human race and pranks by removing people's cothes; Garu finds Karu cool. Blue gems hold his power and are in his collar.
