Janu and Oki arrive in Oki’s spiritual world, which manifests as a blue-hued, ethereal realm featuring a boat navigating toward a hidden garden. During the journey, the two discuss the complex nature of astral projection and their roles as travelers between planes of existence. Oki reveals that she cheated during a previous donut-tossing game by using foresight to peek into a parallel world through another version of herself.
Upon docking, Oki reveals her "zen garden," a work-in-progress dreamscape where she can practice focus and clarity. She demonstrates her control over the environment by temporarily restricting Janu's ability to move. The conversation shifts to the predicament of Anju, who is stranded in their world. Oki proposes a plan: since Janu, Juna, and Anju are all connected to a mysterious train that exists across their realities, they must all board the train simultaneously to potentially facilitate Anju's return home.
Oki acknowledges that she has not yet perfected this plan and expresses a need to refine it further. After their conversation, Oki returns their souls to their physical bodies. The narrative concludes on a surreal note, humorously noting that the spiritual excursion felt like it lasted eight years, leaving the school environment changed and Janu feeling a sense of finality as he and Oki part ways.
