She moved from Tokyo to her father's hometown. She is staying with the Kirishima family, who are her father's acquaintances. She has a sociable personality and gets along with others easily. She confesses that she likes Haruto, but it does not prevent her from helping Haruto get closer to Nanami. It is later on revealed in the manga that she had met Haruto once when they were children at the summer festival, and he found her when she was lost and in tears. She consoled Haruto when he was dumped by Nanami. Yuzuki ends up moving back to Tokyo in order to work things out with her troubled family. Prior to her departure, she accepted Haruto's confession and agreed to have a long distance relationship with him. A short time later, Yuzuki cuts off all contact with Haruto and avoids Haruto's request to meet up. Nanami hears from Rin that Eba apparently has a new boyfriend. Yuzuki apparently "explains" this to Haruto in a letter that came with the shirt she bought for him (that Haruto was ignorant of for around a month before it accidentally fell out of the bag). She explains how she must date a boy from her old middle school and therefore must break up with Haruto. However, after reading the letter Haruto decides that the letter's content was not something Yuzuki would write, and that something has happened to her once again.
