About
Eri is Tsumugu's ex-girlfriend. She is popular and ranked third of the school for her grades, and eventually goes to study abroad at an American university. Eri and Tsumugu dated for a bit, but ultimately broke up because of differing outlooks on life. While they dated, Eri felt unsure about Urara after seeing Tsumugu get along so well with her, while Eri and Tsumugu didn't have that much in common.
