Sarazanmai

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.

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.

The group rescue Haruka after he is kidnapped by Reo, and are transformed back into human form. Keppi explains that Reo and Mabu are agents of the Otter Empire, who have been at war with the Kappa Kingdom for generations over the energy of the shirikodama; with the Kappa Kingdom now defeated, the Otter Empire has begun to extract the shirikodama of humans. In a post-credits flashback set during the Otter-Kappa war, Mabu sacrifices himself to protect Reo in battle.

Kazuki asks for Toi's help to kidnap Sara and so that he can take her place during a meet-and-greet that Haruka plans to attend. Toi's backstory is revealed through a flashback – after his parents died from suicide upon being conned into crippling debt, the family's soba shop was saved from closure through Chikai's intervention. When a yakuza came to collect the family's debt, he was shot by Toi, which was subsequently covered up by Chikai.

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.
