Haruichi is a tall young man with medium-length dark sea-green hair that is tied in a half bun while leaving the rest of his hair down, big dark-blue eyes with thin eyebrows and he usually sports a relaxed expression on his face.

Haruichi is usually a relaxed boy with a observant and cunning personality. Due to this, Haruichi tends to be more level-headed than his peers and prefers to watch the others be rowdy from the sidelines, rather than being mixed in the chaos himself. He always measures himself with those who do better than him and does whatever he can to surpass them, bringing this to a secret one-sided rivalry with Kikoru Shinomiya and an open rivalry with Aoi Kaguragi.
