The anime will premiere in April and will air on Fuji TV 's Noitamina programming block. The staff revealed a story summary at the Animate Girls Festival 2018 event in November:

The stage is Asakusa.

One day, three second-year middle school students — Kazuki Yasaka, Toi Kuji, and Enta Jinai — meet a kappa-like creature named Keppi, who is the self-proclaimed heir to the throne of Kappa Kingdom. Keppi forcibly takes the students' shirikodama (a mythical organ kappa steal through a person's anus) and they are transformed into kappa. Keppi informs them, "If you want to return to your former selves, you need to connect in 'that way' and you must bring me the shirikodama of zombies." Will the three boys be able to connect and take the shirikodama of zombies?

At the same time, two policemen, Reo Niiboshi and Mabu Akutsu, try to do something at the police box where they are stationed.
