Kageyama's height and impressively sharp glare are said to be his most prominent physical features and source of attraction to several female classmates. He is of a lean but muscular build. He often emits an intimidating aura, which is heightened by the almost permanent scowl on his face. His black hair is cropped short, with a fringe that hangs just above his dark blue eyes. His typical attire consists of either his school uniform or practice clothes.
