Sarazanmai

Three middle schoolers, Yasaka Kazuki, Kuji Toi and Jinnai Enta encounter Keppi of the Kappa Kingdom; the three are enlisted to fight kappa zombies.

Kazuki tries to make his kid brother Haruka happy, using any means possible, including theft and deception.

Enta, who has a crush on Kazuki, wishes to earn a dish so that Kazuki will return to playing soccer with him.

Kazuki asks for Toi's help to kidnap Sara and take her place during a meet-and-greet that Haruka plans to attend.

Toi attempts to kidnap Sara, though she evades him by transforming into a kappa, exposing Kazuki's cross-dressing to his family.

After failing to defeat the previous kappa zombie, the three remain stuck as kappa; Mabu and Reo become more desperate for kappa zombies.
