A group consisting of Mob, Reigen, Dimple, Serizawa, Ritsu, and Teru embarked on a journey to Ibogami Hot Springs in Zebra Prefecture. The purpose of their trip was to investigate the mysterious rumors surrounding the inn and save it from whatever dangers threatened it. As they traveled to their destination, Reigen received a request from the matron at the hot spring to uncover the truth behind these strange stories. To ensure that everyone enjoyed the relaxing experience, Ritsu and Teru also joined in on this adventure. However, during their train ride, Reigen and Serizawa became drowsy and somehow found themselves transported into a bizarre parallel world.
