Naozumi Miyamura is a peripheral figure in Horimiya, named as the head of the Miyamura household and the father of Izumi Miyamura. The story keeps him offstage, noting only that where he is now remains a mystery.
The scant detail on Naozumi's looks fixes his hair as dark brown and his eyes as blue, the features of a grown man well into his thirties. He is drawn only sparingly, in keeping with how rarely the narrative sets him on the page.
With so few appearances to his name, Naozumi is given no fleshed-out temperament in the material. He registers less as an active character than as a gap in Izumi's family, a father whose absence carries more weight than his presence.
