During their "battle", Tōka forces Rikka to accept the disappearance of their former house and the death of their father. Yūta tells Tōka that Rikka's delusions are not intended to ignore the truth. Rikka runs away, forcing Yūta to eventually find her on a train headed back home. On the way, Yūta explains to Rikka that he started his chūnibyō behavior when he was isolated from his former friends. Upon arrival at home, Rikka realizes that she forgot her apartment key and Yūta's family is out for the night, meaning that the two will be alone together overnight. Yūta and Rikka go to the corner store to get some food. When Makoto and Kumin later go there, Makoto contacts Yūta for advice, leading Yūta to contemplate if he is in love with Rikka. As Yūta tries to put those thoughts behind him and go to sleep, Rikka appears to be harboring her own feelings for him.
