Iroha Tsuchiura

Iroha Tsuchiura is Shuusuke's childhood friend, who lived in the same city as him until she was five. Years later she returns, befriends Nao and sits beside her in class, with neither girl initially knowing the other's connection to Shuusuke. Iroha lives on a hill near the Takanashi home and uses a telescope to watch Shuusuke. She often wears glasses privately and now wears her hair down rather than in her childhood pigtails.
