The action of the hentai takes place in a small amusement park called Mokomoko Animal Land.
Its main singer and dancer, Ayumi Haruoka, is a bright, cheerful girl who is loved by both children and parents.
But she is secretly being watched by a creepy, obsessed man named Hidaka Yujin, who was recently fired from his job. He takes photos of her and posts them online.
One day, Yujin comes to Ayumi with the photos, blackmails her, and demands sex.
But Ayumi was not what she seemed: her sexual desire was much stronger than he could have imagined.
