Sumika's best friend and classmate who lives alone with her brother, Ushio is a naive girl madly in love with cute girls. She often gets crushes but they are all one-sided. She considers Sumika as a very precious friend, but she's completely unaware of her feelings and often remarks her for being "cool", "not cute" and "not her type", without knowing Sumika's inner reaction at these words. She herself garners feelings for Sumika, but is afraid to act on them based on a bad experience with one of her old friends. She later learns from Tomoe that Sumika is in love with her too, and slowly starts to give Sumika hints.
