He doesn't really like Guest. Their relationship is awkward. A boy whose talent is listed as "Ultimate ???" because he cannot remember what his own "Ultimate Talent" was. He doesn't seem particularly troubled by this, instead remarking that he's "looking forward to finding out what kind of Ultimate" he is. His name was chosen to evoke a mysterious image. Despite his appearance, his "~ssu" speech style (casual/polite hybrid), and his somewhat playboy-ish vibe, he is approachable and interacts with everyone in a friendly manner. However, even when other students fall into chaos, he possesses the composure to press Monokuma and the others about their motives, as well as deep insight into the current situation, acting to avoid the orchestrated tragedy. He is a man of many mysteries, occasionally speaking as if he knows "something" the other students don't, or showing meaningful expressions that make him look like a different person entirely.
