To combat the approaching boredom, friends decide to make a film together documenting their memories together.
Tetsuro finds a reel of film at Kaito's house. Kaito remembers it was made as a test film, so everyone could get use to being filmed. Kaito watches the reel showing Ichika being too self conscious being filmed. Remon gives her an alcoholic drink to get inspiration for the screenplay, which she gets from Ichika's uninhibited behaviour. While Ichika is sleeping off the effects. Remon pours some of the alcoholic drink for Kanna and Mio, resulting in more wild behaviour which Remon films. The test reel finishes and Kanna, Mio and Tetsuro turn up at Kaito's house with fireworks and sparklers. The friends reminiscence about old times.
While testing his high-speed film video camera, first year high school student Kaito Kirishima sees a bright blue light, then an impact has blown him off of his footing and beyond the railings. He sees a hand grabbing his as he fell, bloodied, only to wake up in his futon the next day. At his school, a transfer student named Ichika Takatsuki comes to a third year class. Somehow the both of them has a familiarity with each other when his classmate Tetsuro approaches her and her classmate Remon Yamano, proposing that she joins a movie project he and Kaito are planning. She accepts it without hesitation, and Remon volunteers to write the script. Kaito's classmates Kanna Tanigawa and Mio Kitahara volunteered later. When Kaito goes to test his camera after class, he finds Ichika fishing in the river. He finds out that she has nowhere to go, so he unwittingly offered her to stay at his house, given that his sister will be away for three months. Back home, as Ichika takes a bath, Kaito felt pain in his neck, then sees a flashback of what happened the evening before. Ichika finds him unconscious, with a sign of increased metabolism on the area where that insect bite was. Ichika then calls for her assistant Rinon to stop it, as she kissed him. Exactly as Kanna and Kaito's sister Nanami arrive.
