Keppi gives the group a Dish of Hope as thanks for helping him, which grants one wish to whomever possesses it, and informs them that they can earn more plates by defeating more zombies. Kazuki explains that he cross-dresses for his younger brother Haruka, a fan of Sara's, and that he wishes to earn a dish for him. Toi wishes to earn a dish for his older brother Chikai, a yakuza for whom he sells cannabis. Kazuki and Toi are later forced to pursue Nyantaro, a feral cat cared for by Kazuki and Haruka, after he steals a bag of cannabis from Toi's grow-op. Nyantaro is suddenly captured by a kappa zombie who, upon being defeated, exposes Kazuki's secret that Nyantaro is domestic cat that he stole. In a post-credits scene, Enta encounters a sleeping Kazuki dressed as Sara, and kisses him.

Chikai and Toi make preparations to leave the city. Enta returns the Dishes of Hope to Kazuki, but they are confronted by Reo and Mabu, who intend to use the dishes to restore Mabu. Reo shoots Enta, and takes the dishes.

Kazuki, Enta, and Keppi encounter Dark Keppi, the corporeal form of half of Keppi's shirikodama held by the Otter Empire. Otter, having learned of Reo's plan to use the dishes on Mabu, transforms Mabu into a zombie. Keppi transforms Reo into a kappa, who recovers Mabu's shirikodama and learns that Otter forced Mabu into giving up his connection with Reo in order to live. Mabu tells Reo that he loves him, causing his mechanical heart to explode. A grieving Reo attacks Kazuki, Enta, and Keppi, but is shot and killed by Toi, who wishes to use the dishes to bring Chikai back to life. Kazuki uses the dishes to save Enta's life, and Toi is absorbed by Dark Keppi.

Toi begins to destroy his connection to Kazuki and Enta, but ultimately chooses to preserve it. Keppi fuses with Dark Keppi, with assistance from the group and a revived Reo and Mabu, and defeats Otter and the concepts it represents. Upon performing sarazanmai, Kazuki, Toi, and Enta foresee a potential future in which their connections to each other are eventually severed. In the aftermath, Toi is sent to juvenile detention for three years. Upon his release, he jumps off of the Azuma Bridge, but is rescued by Kazuki and Enta. The three happily run "off to the future" together.
