Kind-hearted. Vice-captain of Class 1-1. He always maintains a relaxed demeanor with a gentle smile. Even in large-scale fights, he is a refreshingly overpowered character who doesn't get a single scratch or drop of sweat. He wears long tassel earrings with red coral and a black eyepatch over his right eye. He has reddish-brown hair parted in a two-block style that covers his eyes, and red eyes. He enjoys wearing Chinese-style clothing regardless of whether he's in uniform or casual clothes. He has a playful side, teasing others with quirky jokes. While he remains calm and composed during battle, behind that smile lies a sharp-tongued side that doesn't hesitate to say things that cut deep. He is gentle to everyone with a mild tone, but his true emotions and intentions are rarely revealed. He is an expert at getting his way or subtly fishing for information. During combat, even if the opponent is an enemy, he often points out their shortcomings and tries to teach them at their level. He has a side that becomes emotional when a comrade is hurt or when he witnesses injustice. This applies not only when an ally is attacked, but also when he sees comrades being treated poorly within enemy ranks or people who have lost their sense of camaraderie. Since his anger doesn't show in his words or expression, it's hard to tell, but he surprisingly has a low threshold for his 'anger switch.' Sakura, who once saw through Suo's other face, remarked that there isn't a shred of kindness in him and that he has a terrible personality. He adds '-kun' when calling others by name. When adding 'Senpai' to a name, he doesn't use '-kun' and just says Name + Senpai. He is the epitome of 'the kindest people are the scariest when angry.' He doesn't push away or ignore the weak; he has the flexibility to quickly grasp the situation, identify who he needs to protect, and determine what action to take. If there are other strong comrades present, he focuses on protecting those in trouble or helping comrades who are unskilled at fighting rather than leading the offensive. While he seems like a mentor leading others to the right path, he is also desperate to hide his dislikes; for example, at a gathering where everyone confessed their pathetic traits, he brushed it off with a joke about being afraid of manju, saying nothing else came to mind. Unlike his usual self, he sometimes becomes emotional or regains his reason to recall his original purpose. Besides pure attack power, he has an excellent ability to read the flow of battle and make it his own. Rather than facing enemy attacks head-on, he flexibly evades them and uses the momentum for a counterattack; conversely, when the opponent retreats, he actively closes the distance to apply psychological pressure. After holding back his emotions, he finally burst into tears of sorrow, unlike his usual self (he has always suppressed his feelings by just smiling). He is under a lot of stress and not in good condition.

His face turns red easily when complimented. His face turns red easily in general. He speaks informally to everyone and rarely calls people by their names.
