Ano Natsu de Matteru OVA (Waiting in the Summer OVA)
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.
