Akito Kanno, a second-year Seiin High student, serves as the boys’ volleyball team’s opposite hitter. His sensitivity to sunlight—later identified as solar urticaria—requires long-sleeved attire year-round and restricts prolonged outdoor activities. When teammates train outside, he joins the girls’ team for indoor drills.

His match attire features a navy blue jersey with sky-blue and white striped sleeves, paired with matching shorts. The number "4" and school name adorn the chest, while white kneepads, compression sleeves, and black-accented volleyball shoes complete his gear. Off-court, he favors oversized layers like a light gray hoodie draped over his uniform to shield his skin.

Quiet and introspective, Akito carries a subdued presence, often gazing downward. His given name combines the kanji for "autumn" (秋) and "person" (人), while his surname merges "coffin" (棺) and "field" (野).
