Synopsis
My name is Suzuo Sakurasaki. As you all know, I'm a hero who is a childcare worker and a hero called Dokkoida. Well, even so, it seems that people are laughing at me because I always thrust my head into the ground. Anyway, today I came to the amusement park with Asaka, a very beautiful classmate who lives in the same apartment, and Ruri-chan, who is aiming to conquer the earth due to the habit of elementary school students. And there again Maron Flower, a class A space criminal ... But I can't transform into a dokkoider because I can't get out of the Ferris wheel. Ask, Nerroid Girl, please help me ~ !?
