On Earth, the leader of planet Valhalla arrives, bringing a virtual program called the "Bride Training Boot Camp" along with her. This program is created to recreate numerous hypothetical situations that could arise during marriage, with randomized cards assigned to different pairs depicting their unique predicaments. For instance, Kazuto and Valkyrie are tasked to prepare a meal, Raine and Kazuto's sister need to address poverty, while Akina and Hydra must plan their own wedding as both the bride and groom, ultimately facing unexpected and mismatched scenarios.
