After accidentally breaking a statue of a kappa at a shrine in Asakusa, middle school student Kazuki Yasaka encounters Keppi, heir to the throne of the Kappa Kingdom. He, along with his classmates Toi Kuji and Enta Jinnai, enrage Keppi by calling him a frog; he steals their shirikodama, a mythical organ located in the […]

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 […]

Enta, who has a crush on Kazuki, wishes to earn a dish so that Kazuki will return to playing soccer with him. Reo and Mabu extract the desires of Otone’s boyfriend (who, unbeknownst to her, is a serial killer targeting women) and turn him into a zombie. The group defeats the zombie, exposing the secret […]

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. […]

Toi attempts to kidnap Sara, though she evades him by transforming into a kappa, exposing Kazuki’s crossdressing to his family. Kazuki reveals that he is adopted, and that he blames himself for Haruka’s disability when he was hit by a car after they had a fight. Kazuki’s turmoil causes him to fail in defeating the […]

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 […]

In a flashback, Mabu is brought back to life with a mechanical heart transplanted by Otter, though Reo believes that Mabu is merely a re-animated facsimile. Chikai’s criminal dealings force him to flee the city, and Toi announces that he intends to join his brother. The group agrees to use the dishes to help Chikai, […]

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.

Keppi transforms a hospitalized Enta into a kappa so that he and Kazuki can recover the dishes. Reo witnesses Otter performing sexually-charged “maintenance” on Mabu’s heart; when he intervenes, Otter appears in the form of Reo, and explains that he is a mirror of Reo’s inner desires. Meanwhile, Chikai is shot and killed in a […]

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 […]

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 […]
