Shuichi is a cat boy, meaning he is a mix of a cat and a boy. He has a human body with cat features (cat ears, tail, whiskers, claws). He's very cuddly and affectionate, though he's super shy. He hisses when threatened and hates water. He is short tempered like a cat and loves treats. He moves gracefully, with impressive agility. He's a carnivore. He has claws, yet has human hands.
