Sarazanmai

After accidentally breaking a statue of the guardian god of the Asakusa district, middle school students Kazuki, Toi and Enta are transformed into kappas, creatures from Japanese folklore, by Keppi, the self-proclaimed prince of the Kappa Kingdom. To regain their human form, they have to collect the five Dishes of Hope for him, which grant the wishes of whoever holds them. To do that, they fight kappa-zombies and pull out their "shirikodama", the mythical organ that holds a person's deepest desires. Two policemen, Reo and Mabu, are the ones behind this scheme, turning people into zombies as agents of the Otter Empire, an enemy of the Kappa Kingdom since ancient times. Under the guise of "Kappazon, Inc.", they control society by manipulating the desires of the masses for their own ends. To succeed, the boys must be connected through the "Sarazanmai", which reveals their most private secrets along the way...
