After dressing Yukimura up as a butler, Yozora agrees to play a dating sim for girls that Rika brought in. Whilst initially finding the game to be stupid, she takes interest in a delinquent character, though ends up downhearted when she winds up with a bad ending. Later, Rika invents a time machine, which sends Kodaka's conscience back to day he last saw Yozora before he moved years ago. He decides to tell Yozora about the move, only for things to get really weird. As Rika later reveals the time machine is in fact a hypnotic sleep device that allows him to see any dream he wants, the fact he knew Yozora ten years ago is brought to the attention of the club.

Yozora, Sena, Rika and Yukimura go with Kodaka to Nagaya in order to pick out a present for Kobato's birthday, despite wanting to go alone with him. As Kodaka helps Sena out with her shopping first, they talk about whether Kodaka would consider getting a girlfriend and what Sena thought of him and Yozora being past friends. After Kobato's party ends rather well, Maria and Kate show up to join Kodaka and Kobato for sukiyaki, with Maria also bringing Kobato a present.
