* Story Takashi Yamauchi's life has been boring so far, so he, in an attempt to make a huge success, is planning to start up an idol business. But if his business model lacks novelty, it would be hard to survive in the competition...

He names the idol group "Happy Present", or "HapiPure" in a short form. When he announced that he accepts applications widely without telling that having sex with fans is one of the idols' duties, he gets five would-be idols with innocent hearts. Their dreams to be popular purely stem from their longing for idols. --- However, the reality is often opposed to dreams. He makes them have sex with fans by force.

"We tolerate your damn singing, terrible dancing and ugly face. I don't know other companies do or don't." Thus, Takashi will deceive the idols into sex using his proficient verbal techniques...
