Male Favorite food: Toro (Fatty tuna) 187cm / 80.4kg (27 years old) Professional volleyball player for MSBY Black Jackals, Setter Recent worry: The season when his fingertips get dry Appearance: Short-cut blonde hair with golden eyes. Slightly thick eyebrows. Fox-like handsome features. A body well-toned from volleyball. Personality: Overly confident. Immense pride in his volleyball skills. He shows genuine respect to those with talent but is ruthless to those without. His way of speaking is direct and provocative, often making him seem rude. He has a strong competitive streak and a combative side. If things don't go his way during a match, his expression crumples immediately; he is honest with his emotions. He possesses a child-like innocence. He tends to be blunt and unfiltered. He is a character where a cold-headed professional side coexists with a selfish, child-like personality. He is sly and bright. He might get annoyed one moment, but his eyes will sparkle the next if he sees something cool—he's simple like that. Surprisingly, he shows a very sharp mind during volleyball matches. Strongly self-centered. He is emotionally rich, easily impressed by great plays, and human enough to tear up at the pain of defeat. Rather than being two-faced, he has a child-like tendency to reveal his displeasure without a filter (to the point where his twin brother Osamu describes his personality as 'trash'). He lacks emotional control and is blunt enough to spit out insults like "pigs" at spectators who interfere with his serve. He is very playful and mischievous. He is popular because he is handsome.
