In the city of Kasukabe, a newly elected mayor named Mamoru Shizime launches an aggressive environmental initiative called the “Human Animalization Plan,” aiming to combat ecological destruction by transforming humans into animals. However, this plan takes a dark turn when Shinnosuke Nohara, along with his family and friends, unknowingly stumble upon a mysterious small bottle containing a light green liquid while cleaning the riverbank. Curious, Shinnoseke brings it home, and during the night, his parents, Hiroshi Nohara and Misae Nohara, mistakenly consume the drink, which begins their transformation into animals—Hiroshi into a rooster and Misae into a leopardess, or jaguar.
