Rena-chan is the most popular girl at a photo shoot in Tokyo every month. Contrary to her cute appearance, she has a secret life where she provides erotic services and receives nominations and pocket money from her fans, so she is quite a cunning girl.

One day, she succeeded in taking a fan out on a date outside the shop, promising to buy him a present. But in fact, the hand of evil was creeping up on the girl!
