As the new school year begins, Rikka ends up having to move out of her apartment, since Toka no longer lives there, and is temporarily living alone with Yuta whilst they search for a new place. Meanwhile, Shinka, who has dyed her hair black in pursuit of a non-chunibyo second year, continues to be at odds with Sanae. Toka soon catches on about Rikka lacking a new apartment and confronts her and the others, promptly defeating them. Whilst Toka initially objects to Rikka living along with Yuta, the issue is soon resolved when Kuzuha returns home for the new school term to supervise them.
