When Kazuki, Toi, and Enta make the grave mistake of calling Keppi—self-proclaimed heir to the Kappa Kingdom—a frog, they experience some serious butt hurt when he steals their shirikodama! Transformed into Kappas, the only way they can change back is to take the shirikodama from zombies. But they’re not the only ones on the job, policemen Reo and Mabu are butting in!
