Tenant in room #4 at Hidamari Private Boarding House. Shin is a ladies man and perverted. He is madly in love with Keiko, though she can't stand him. Shin plays third baseman on the Myōjō High School baseball team. He has a telescope, ostensibly for observing the stars, though more often uses it to peep at neighborhood females. Shin is deathly afraid of cats.
