Mio Kanzaki

Mio Kanzaki is a first-year student in the koto music club at Hakuné High School, gifted with a rare neurological phenomenon known as synesthesia—allowing him to perceive musical sounds as vivid colors and distinct shapes. Known for his calm demeanor and measured speech, Mio possesses an almost instinctive technical precision when it comes to playing the koto. Yet beneath that flawless performance lies a quiet restlessness; he once grew weary of playing music that was technically perfect but emotionally hollow. Everything changed after an exchange with Tokise High School, where the uniquely expressive tone of Ai Kuzure sparked his genuine curiosity and drew out a side of him rarely seen—an openness to connect.
