Introduced in the first chapter, Yuuri's high school life is parallel to Futaba's middle school life. She is very cute, causing her to be despised by many girls in her class, and she is often left alone. Yuuri gets by very well, however, for she prefers to be hated for who she truly is than to be liked for someone she isn't. Yuuri and Futaba soon become best friends. She falls in love with Kou after he helps her during a class leader's camp. Yuuri greatly treasures her friendship with Futaba, but often gets jealous of Futaba's closeness with Kou.
