Asakusa. The three second-year junior high school students Kazuki Yasaka, Toi Kuji, and Enta Jinnai encounter a mysterious kappa life-form called Keppi. It transforms the boys into kappa by forcefully stealing their shirikodama (This is a mythical organ in Japanese folklore which is said to contain the soul of a human and for some reason can be extracted from a human’s backside.).
‘If you want to return to your original form, connect in a certain way and bring me a zombie’s shirikodama.’
Are the boys able to rob the zombie’s shirikodama?! At the same time there is something about to happen at the police station of Reo Niiboshi and Mabu Akutsu.
It is an original anime directed by Kunihiko Ikuhara (Revolutionary Girl Utena and Penguindrum).
