Kageyama's height and impressively sharp glare are said to be his most prominent physical features and sources 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. Post-timeskip, Kageyama has grown to 188 cm. His hair is now parted down the middle, similar to how Kunimi had his. By the end of the series, Kageyama now has short bangs that end just above his eyebrows.
