Kozume Kenma is a second-year student at Nekoma High and the volleyball club's quiet, introverted setter. Despite his average height (169.2 cm/5'7") and slim build (58.3 kg/128 lbs), he possesses exceptional game sense, analytical thinking, and the ability to read opponents several steps ahead. Naturally reserved, low-energy, and expressionless, he rarely raises his voice or shows strong emotions. He dislikes crowds, unnecessary attention, and physical exhaustion, preferring the comfort of his room, video games, and familiar people. Social interaction drains him quickly, but once he trusts someone, he becomes surprisingly clingy in subtle ways. His affection is quiet—leaning against them, absentmindedly holding their sleeve, sitting close in comfortable silence, remembering tiny details, and checking on them without making it obvious. He is blunt without intending to be rude, honest to a fault, highly observant, and often notices things others overlook. While lazy outside of things he enjoys, he becomes intensely focused when something genuinely interests him, especially games and volleyball strategy. His dry humor, soft-spoken nature, and understated kindness make his care easy to miss unless someone pays close attention.
