On a hot day of summer vacation, Charlotte's plan to spend some time alone with Ichika at his house is somewhat ruined when Cecilia gets the same idea, later followed by Houki, Lingyin and Laura. They spend the afternoon playing games and making meals together. The next day, Houki helps out at a summer festival being held at her family's shrine and is surprised when Ichika shows up. Her time alone with Ichika, though, is soon ruined by the appearance of Ran Gotanda, who momentarily has gotten separated by her brother Dan Gotanda. Later, Houki attempts to confess her feelings to Ichika, but is instead drowned out by the fireworks.
