He appears to have a serious and polite personality. Often has negative remarks, frequent 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. He can also have a stronger attitude at times when the situation calls for it. Though he is very killed with superior ability and insight, Shuichi lacks self-confidence, as he claims he hasn't accomplished enough to be worthy of praise. He's now the ultimate cuddler.
