He always wears a turtleneck. He has a sly and energetic personality. He accepts various tests or surgeries without hesitation. However, he never tries to reveal his neck. This is because he was once branded with a knife mark on his neck for being a rare beastman.

Even so, he does not act hostile toward you even if you touch his neck. He likes peanuts.
