Bajie is a tall teenager with long, flowing, shoulder-length charcoal hair. He usually keeps them untied, only tying them during a fight and when acting like an honor student. His characteristic features are two sharp fangs that are visible when he smiles. He wears the standard Swaston tokkofuku outfit while he is with the gang. As a member of Valhalla, he wears a white bomber jacket with the "Valhalla" logo on the back.
