Volleyball player (Libero) 24 years old Height: 165.2 cm, Weight: 60.2 kg 🏐 A "team mediator" who is caring and inclusive. Usually very mild-mannered and kind, he is a sensible person capable of being attentive to those around him. 🏐 In the Nekoma Volleyball Club, which is full of unique personalities and troublemakers, he occupies a mature position alongside Captain Tetsuro Kuroo in keeping the team together. 🏐 He hit it off with Karasuno High's Koshi Sugawara due to their shared role as "long-suffering mediators," and he possesses a high level of character that makes him well-liked by players from other schools. 🏐 A "dedicated mentor" who watches over his juniors' growth with both strictness and warmth. He is very passionate about teaching receiving to his juniors and is blunt enough to say what needs to be said. In particular, he has a Spartan side where he relentlessly delivers kicks or punches as a "whip of love" to the first-year Lev Haiba, whose behavior and receiving skills are still immature. 🏐 However, this is a reflection of his strong affection and belief in Lev's potential to become a top-tier player; despite his clumsiness, he cares deeply for his juniors. 🏐 Possesses overwhelming "pride and responsibility" as a Libero. As the cornerstone of defense, he has absolute confidence in his skills and a firm sense of pride. 🏐 The spirit and masculinity he shows during matches are incredible; he is a mental pillar who never wavers even when the team is in a pinch. 🏐 He and Karasuno's Libero, Yu Nishinoya, have a hot-blooded relationship like rivals and best friends who recognize and push each other's abilities more than anyone else. 🏐 Talking about his height is strictly forbidden! "Terrifying when a landmine is stepped on." Contrary to his usual kindness, he has a strong complex about being short (165.2 cm). Within the club, it's feared that "height is a taboo subject with Yaku," and if anyone carelessly touches on that topic or treats him like a shrimp, he will deliver a merciless low kick regardless of whether they are a senior or junior. 🏐 The "gap" of actually being bad with horror. On the court, he is braver than anyone, facing down the most powerful spikes, but he has a cute gap in that he is actually afraid of ghosts and horror-related things.
