The summer festival comes, and it will be the only day Keita will be free from all the prep school work. This means that Ako and Riko will be competing for a night at the festival with him, although they all go to the festival together. But a few incidents involving paraders enables Ako and Riko to indeed spend some time with Keita alone. They also had to contend with Kiryu-sensei (who was patrolling the fair and catches Riko and Keita in the forest), Mikazuki, who is Miss Mikoshi, and a (ahem, naughty) chick that Ako bought that caused Keita to see Miharu peeing in the bushes. Shocked, Miharu drops on the ground what seems to be a love letter.
