The Asakusa neighborhood of Tokyo is the setting for the original anime Sarazanmai, where the three friends Kazuki Yasaka, Tooi Kuji, and Enta Jinnai meet Keppi, a creature claiming to be the successor to the Kappa kingdom's throne. The three middle school students are unceremoniously transformed into kappas by Keppi when she steals their shirikodama, a legendary organ that kappas must steal in order to access the livers of their victims. Keppi tells them that they must now gather the Shirikodama from the zombies and bring it to him in order to become human again. Additionally, he instructs them on how they must interact with one another.
Can the three altered guys gather enough Shirikodama to revert to their original state?
