An ensemble cast from across the timeline assembles for a single purpose. When such an event occurs, it means they face a cataclysmic threat that none of them could ever face alone. However, what they actually end up doing is surprisingly mundane.

Rikka has entered her third year of highschool and is still a chunibyo. It is spring break and university exams are approaching. Toka has decided to take Rikka to Italy with her, because of her work. Toka believes they should move as a family. Yuta thinks that Rikka and him will be separated. Nibutani as well as the other members suggest that Rikka and Yuta elope. This starts their travels through Japan.
