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...

Izumi-kun and his friends are busy getting ready for the school's cultural festival. Izumi-kun is working with the group in charge of making costumes for their class's display, and Shikimori-san is in the group working on decorations. They don't get many chances to talk, and when they each see the other having fun chatting with their groupmates... And then the festival begins at last. Izumi-kun is so busy his head is spinning, and this causes his unlucky nature to awaken yet again. On top of that, he's on duty in the library the next morning. The one on duty with him is Kamiya-san, whom he first met the previous year through the library committee. But she's acting a bit different today...

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...

Shikimori-san is at the mall to buy an outfit for the first date she and Izumi-kun have had in a long time. For some reason, her older brother, who still treats her like a child, is at the mall with her. Her brother is actually quite shy around people he's never met, and before he knows it, he's surrounded by young women and unsure what to do. Shikimori-san takes him by the hand and leads him away, which reminds her of how she always used to be the one dragged around by her brother's hand.... and of the days when she didn't know what she wanted to do with her life.
