It's the day of the school's ball sports tournament. Izumi-kun is playing soccer with the boys, and Shikimori-san is participating in the girls' volleyball match. Izumi-kun knows he can't contribute much, but he plays his hardest anyway. Shikimori-san worries about him, given his natural unluckiness... and surely enough, he gets hit in the face by a soccer ball and blacks out. He ends up in the nurse's office while Shikimori-san looks after him, meaning the two of them are alone. Then Shikimori-san says she's going to stay with him instead of heading back to play in the volleyball match...

Summer begins at last! Izumi-kun joins Shikimori-san and their friends in deciding what they'll all do together over summer break. They decide to go to the river, but is the combination of a river and Izumi-kun's bad luck too dangerous? Then Shikimori-san says something amazingly cool... After some discussion, they all head to the mall together. Shikimori-san seems disappointed when Izumi-kun says he won't wear a swimsuit at the river. She says she won't wear one either, but then Izumi-kun does something that lights a fire in her...

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...
