Yamato's childhood friend from Hiroshima, she is also the same girl from the original firefly confession. Starting next year, she will be attending a fashion school in Tokyo. For now, she is staying at Ayano’s dormitory for about a week while visiting. She often embarrasses and pesters Yamato.
It has been revealed that during the original firefly confession, she did not reject him as initially thought. Instead, she couldn't give an answer because Yamato ran away and avoided her afterwards. She plans on attending Touto University, contrary to Ayano's belief that she would go to a vocational school. She encouraged Yamato to attend Touto University as well and made him pinky swear they would go together.
She is very perceptive when it comes to Yamato, to the point where she can accurately guess his thoughts and feelings. She has hinted that she has feelings for Yamato, but he misinterprets them as part of her playful nature. When she leaves Ayano's dormitory, she tells Yamato that he still has feelings for Suzuka and releases him from their promise so he can join Suzuka at Seijo University.
