Summer break is here at last! Izumi-kun and his friends arrive at the river, where they get started with a barbecue. As they divide up the prep work, everyone suddenly feels very anxious... because Izumi-kun has picked up a kitchen knife! Even Shikimori-san's eyes grow wide... but she's once again charmed by Izumi-kun and his ability to do just about anything. After the barbecue, they all decide to play in the river, but Izumi-kun gets into some trouble...

During the cultural festival, Izumi-kun and Kamiya-san have a good time chatting as they share library duty. Then Nekozaki suddenly comes along and takes Kamiya-san away to see Shikimori-san. When Kamiya-san hears what Shikimori-san wants from her, she readily agrees. Later, when Kamiya-san returns to her classroom to help with her class's festival project, her elegant look draws a crowd of classmates and guests around her. As she drowns in all the noise, a certain someone suddenly comes to mind, and she breaks away from the classroom.

Preparations are underway for the school's athletic festival. Izumi-kun was hoping to avoid being placed in the highlight event, the boys and girls mixed relay, but unluckily enough, that's exactly what he's chosen for. But Shikimori-san and all of their friends end up on the relay team with him, so he feels like it'll actually be fun this time. The gang wastes no time starting to practice for the race, but it doesn't go so well for Izumi-kun and Hachimitsu. They refuse to give up, continuing to practice until the day of the festival comes. Hachimitsu seems to be in very low spirits before their event starts...

The day of the amusement park date has finally come. Izumi-kun is all fired up as he works out a plan to make sure Shikimori-san has a good time. After some shopping at a store that sells costume goods, the first attraction they head to is one based on the tale of Sleeping Beauty. The line is long, but since they're together, the time flies by. When they finally board the ride, it's so comfortable that Izumi-kun falls asleep, and when Shikimori-san sees this... The distance between them continues to shrink!
