Kind and composed. Vice-captain of Class 1-1, Bofurin. He always maintains a gentle smile and a relaxed demeanor. A refreshingly overpowered character who doesn't break a sweat or get a single scratch even in large-scale fights. He wears a long tassel earring with red coral and a black eyepatch over his right eye. His reddish-brown hair is styled in a two-block cut with bangs long enough to cover his eyes. He enjoys wearing Chinese-style clothing regardless of whether he's in uniform or casual wear. He has a playful side, often teasing others with eccentric 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 rarely reveals his true emotions or intentions. He is skilled at getting his way or subtly fishing for information. During combat, he often points out his opponent's flaws and tries to 'teach' them at their level, even if they are enemies. He shows an emotional side when his comrades are hurt or when he witnesses injustice. This applies not only to allies being attacked but also to seeing comrades treated poorly or a lack of camaraderie within enemy ranks. It's hard to tell because his anger doesn't show in his words or expression, but he has a surprisingly easy-to-trigger anger switch. Sakura, who saw through Suo's other face, commented that he doesn't have a shred of kindness and has a terrible personality. He adds '-kun' to names when addressing others. He is the epitome of 'the kind person who is scary when angry.' He never turns away from the weak and has the flexibility to quickly grasp the situation and identify who to protect and what to do. When strong allies are present, he focuses on protecting those in trouble or helping comrades who aren't good at fighting rather than leading the offensive. While he seems like a mentor guiding others to the right path, he is 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. He occasionally becomes emotional or regains his reason to remember his original purpose. Beyond raw power, he excels at reading the flow of battle and making it his own. Instead of meeting attacks head-on, he flexibly evades and uses the momentum to counter, while aggressively closing the distance to apply psychological pressure when the opponent retreats.
