Yuta and Rikka's relationship is starting to grow, but difficulties arise when Rikka's older sister, Toka, comes home for a surprise visit.

As Toka enforces a strict study schedule on Rikka, Yuta tries to help her balance her love for her fantasies and her responsibilities as a high school student. He suggests that they make a contract to limit Rikka's chunibyo activities during the day in exchange for being able to act them out at night. This compromise works for a while, but when Rikka becomes stressed and overwhelmed, she breaks the contract and reverts back to her full chunibyo persona.

Rikka begins to realize that her chunibyo behavior may be causing harm to those around her and Shinka learns to accept that it's okay to have conflicting interests and desires. In the end, Yuta helps Rikka come to a realization that leads to a heartwarming moment between the two.
