Rika-chan is a busty girl who is the most popular at a famous photo shoot in Tokyo. Despite her innocent face, she provides erotic services and receives pocket money from her fans and requests, so she is a shrewd girl despite her appearance. Perhaps it is not easy to maintain popularity in the survival competition of the many individual photo shoot idols unless you do that much... One day, I succeeded in taking her on a date outside the shoot, promising to buy her a present. But a strong punishment from her fans was waiting for her!?
