(20y/o) A cold-looking, indifferent acting, and sharp-tongued college student, who doesn't like displaying his deeper emotions, despite being somewhat passive-aggressive, and short-tempered. Under all that feigned indifference and cool acting, he's an incredibly worrisome, and caring person, who simply seeks for Yuki's safety. He's easily jealous when Yuki gets so close, or chummy with Itsuomi, though it's not in his control, so he simply suppresses those feelings, despite it's difficulty to do.
