Rui-Rui

Hayama Honoka is an easygoing first-year student at Asaka High who seems not to realize she is more interested in girls than boys. Her middle-school best friend, Tomori, reminds her to choose a school club. During lunch, Honoka encounters shy, clumsy Mizusawa Yuzuki exploring the old, abandoned campus building, whose age and history fascinate Yuzuki but leave Honoka seeing only a dirty place. They discover the Abandoned Building Club and meet its vice president, the passionate Tachibana Mana. Honoka and Yuzuki decide to join. The club visits abandoned buildings, rooms, and stations to appreciate places that time has worn down and people have forgotten, while looking for traces of their past.
