A lively fireworks festival. Yanagi Takayama wins a pair of diffraction glasses at a ring toss game. She chatters with her friend Touko Fukami. Touko tries on the glasses when, amidst the hazy scenery, she hears a voice say "I've finally found you".

Touko Fukami, having just moved from Tokyo, isn't sure she will be well there. By coincidence, she meets Kakeru Okikura at the station. He takes her to Kazemichi Cafe, where she meets Yukinari Imi, Yanagi Takayama, Sachi Nagamiya and Hiro Shirosaki. They set out to watch fireworks that night.

Touko is shocked by the world she saw, and loses consciousness at the end of Kakeru's mother's performance. At Touko's request, Kakeru's mother plays once more, as she wonders about Kakeru's future. Meanwhile, at Kazemichi, Yukinari, Yanagi, Hiro and Sachi arrive all by coincidence.
