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...
