Shuichi's outfit is double-breasted and pinstripe, thin, grey stripes over a black uniform. Most of the time, Shuichi wears a black cap with three white stripes lining the back of it, and a silver star pinned near the front. Shuichi appears to have quite a serious and polite personality. He often has negative remarks, frequently blushes and suffers from a cold sweat. His hat is an especially sore subject for him and he dislikes to look at other people's eyes, which is why he wears it.
