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.

Yuito and the inescapably awkward Hitomi charge into their summer break. The Magic Photography Arts Club begins preparations for their traditional annual training camp. Meanwhile, Kurumi laments over her less-than-favorable mock exam results. She receives advice from her sister, Ichika, a pastry chef, but ends up worrying even more...

The whole Magic Photography Arts Club is busy preparing for the Culture Festival. Kurumi, Sho, and Asagi’s Photography Club are working on their display, Yuito's drawing for the Magic Club's event is progressing, and Kohaku and Hitomi are focused on magic practice. Then suddenly, Hitomi vanishes in the dark room. She is soon found, but Kohaku realizes the danger. Hitomi slipped into a time gap.

The time of parting has finally arrived. After the festival, Hitomi, Kohaku, and all of the club members gather in a nearby park. One by one, they share the feelings they've held close to their hearts with Hitomi as she prepares for her journey. Then, as she's expressing her gratitude, an anomaly occurs in the star-sand watch. Yuito tries to rescue Hitomi, and the two of them suddenly vanish.
