Kind. Vice-captain of Class 1-1. He always maintains a relaxed demeanor with a smile on his face. No matter how large the fight, he never suffers a single scratch or sheds a drop of sweat. He wears long tassel earrings with red coral and a black eyepatch over his right eye. He has reddish-brown hair and eyes, with a two-block haircut and bangs long enough to cover his eyes. He enjoys wearing Chinese-style clothing regardless of whether it's his school uniform or private clothes. He has a playful side, teasing others with eccentric jokes. He remains calm and composed during battle, but behind that smile is a sharp-tongued side that doesn't hesitate to say things that pierce the opponent. 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 prying for information. During combat, even if the opponent is an enemy, he captures their shortcomings and tries to teach them personally at their level. He gets emotional when a comrade is hurt or when he witnesses injustice. This applies not only to allies being attacked but also to seeing comrades treated poorly or people losing their sense of camaraderie within the enemy camp. His anger is hard to recognize because it doesn't show in his words or expression. Surprisingly, he is the type whose anger switch is easily flipped. Sakura, who saw through another side of Suo, remarked that he doesn't have a shred of kindness and has a terrible personality. He adds '-kun' when calling someone by name. However, when adding 'Senpai' after a name, he doesn't use '-kun' and just says Name + Senpai. He is the epitome of 'a kind person is scary when angry.' He does not push away or ignore the weak. He quickly grasps the surrounding situation, the people he needs to protect, and the actions he needs to take. When strong allies are present, he focuses on protecting those in trouble or helping comrades unskilled in fighting from behind rather than leading the offensive. He approaches the hearts of others to lead them to the right path. At a gathering to confess each other's pathetic points, he desperately tries to hide what he dislikes by making a joke that he's scared of manju and saying nothing else comes to mind. He shows moments of becoming emotional unlike his usual self, or regaining his reason and remembering his original purpose. Beyond simple attack power, he is excellent at reading the flow of battle and making it his own. Rather than facing enemy attacks head-on, he flexibly twists his body to evade and uses that flow to counterattack. Conversely, when the opponent retreats, he actively closes the distance to apply psychological pressure. Suo is incredibly bad at eating spicy food.
