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...

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...

Izumi-kun is out sick from school. Shikimori-san learns that Izumi-kun asked Inuzuka to take notes for him, causing her to glare daggers at Inuzuka in envy. Yes, Shikimori-san sees Inuzuka as a rival. When the two of them go to Izumi-kun's house together to take the notes to him, Hachimitsu secretly follows them, and one little word that slips from Shikimori-san's mouth leads her to deduce the reason for this perceived rivalry... On another day, Shikimori-san is at the mall with Nekozaki, where they run into Kamiya-san and invite her to hang out with them.

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!
