A second-year middle school student who transferred into Kazuki's class. Introduced as a gloomy, rowdy delinquent on the neighborhood, he met with Azuma Sara on the day of his transfer, trying to break into a car.

The stage is Asakusa. One day, three 2nd-year middle school students — Kazuki Yasaka, Tooi Kuji, and Enta Jinnai — meet a mysterious kappa-like creature named Keppi, who forcibly takes their shirikodama (a mythical organ kappa steal through a person's anus) and transforms the boys into kappa.
 
Keppi informs them, "If you wish to return to your former selves, you must connect in 'that way' and bring me the shirikodama of zombies." Will the three boys be able to connect as they steal shirikodama from zombies?! Meanwhile, two policemen — Reo Niiboshi and Mabu Akutsu — are up to something at the police box where they are stationed.

Keppi has a task for the boys if they want their bodies back: work for him to hunt down zombie kappa born of twisted human desires. Even scarier, though? They’re going to have to expose their own deepest fears and desires to each other to do so!
