Charlotte visits Ichika at his house. Her brief alone time with him is interrupted by Cecilia, who brings a box of delicious cake. The girls agree to an alliance so that they can both share in taking bites out of Ichika's slice; but before they can feed Ichika in return, Houki, Lingyin, and Laura arrive as well. A little troubled that five people suddenly showed up, Ichika proposes to play a game, and suggests a game that came from Germany where a person uses clay to mold something and the other players guess what it is. During Laura's turn to make something, she claims what is being made is a mountain when Houki thought it was an oil well. After a while, it is around the time for dinner, and they go to the local market picking up ingredients. Ichika and Houki talk a bit, only to be interrupted by Lingyin and Charlotte yelling out to Ichika to help them and prevent Cecilia from picking ingredients. Back at Ichika's house, they are cooking. During the actual cooking Laura shows Ichika what she made. She claims it was oden, although what she made was ingredients of oden on a stick. Cecilia eventually ends up blowing up a pot by using the laser from her optical drone to heat it up. After dinner, the scene goes to Chifuyu and Maya are out at a bar drinking. They talk about Ichika. Maya notes on the aspect of kindness, Ichika and Chifuyu are similar.
In the second half of the OVA, Houki visits her Aunt Yukiko's shrine, and they prepare for the summer festival. Her aunt asks Houki in doing the Kagura dance this year. During the festival, Ichika appears as Houki is maintaining a stall. After seeing him, her aunt allows her some free time. They meet Ran Gotanda and walk around the festival. The three hang out until they find Dan Gotanda stressing over not finding his sister. Houki leaves to prepare for the Kagura dance. When she does the dance, she mesmerizes the audience and Ichika. After the dance she and Ichika goes to high place to enjoy the fireworks display alone. Houki almost confesses her love for Ichika but is interrupted by the fireworks.
