Shuichi appears to have quite a serious and polite personality. He often has negative remarks, frequently blushes and suffers from a cold sweat. With his unsure demeanor, he has a tendency to assume that other people can do things better than him. Among the sixteen students, he stands out for his submissiveness but also for his level-headedness. He always wears a black cap, for his fear of facing people in the eye. He has short dark blue hair with a small ahoge, along with gambogeish grey eyes.
