Hitomi Tsukishiro, a girl from a family of mages who lost the ability to see color when young, gets sent 60 years into the past when her grandmother Kohaku tells her one night to go back in time and visit her when she was a 2nd-year student in high school. Hitomi finds herself in Yuito Aoi’s room, a student at Minamigaoka High School, and tries to escape, but Yuito’s friend Kurumi Kawai sees her.
Hitomi sees the picture Yuito drew, and for a moment, her world regains its color. Now homestaying at Kohaku's house while Kohaku is abroad, Hitomi is urged to enroll at the nearby Minamigaoka High School by Kohaku's parents. A reluctant Hitomi comes to know an unexpected side of her young grandmother. Then, to prove she is a mage, Hitomi demonstrates her magic in front of the other students.
The hands-on “club introductions” for new students have begun. Unable to forget Yuito's drawing, Hitomi visits the Photography Arts Club. Hiding her inability to see color, she takes up a paint brush for the first time in her life, at Yuito's request. She is then roped into their photo shoot. Petitioned by Kurumi, Hitomi is given the role of photo model, landing her in some unthinkable trouble.
