Based on the game by Black Lilith.
Igawa Asagi is a veteran Shinobi. After defeating her archenemy a long time ago, she thought she could finally settle down. Yet, her archenemy was revived from death through a pact made with the head demon in the city and swearing to take revenge on her by hurting those who are close to her. Her boyfriend, her sister (also a Shinobi) and she herself are part of the act being abused emotionally and… sexually…

She does what she has to, to be able to provide for her family… even if it includes indulging this sick old man in his perversions…

Saori is cute, perky, and dreams of being a star! Along with the beautiful Yuna and the striking Erica, Saori is part of a new female pop group named Twinkle – and this hot little group is ready for their big debut!
But this tantalizing trio is about to discover that the music industry is ruthless and demanding of its female artists! First, band manager Masaki decides to give Yuna and Erica a special session in pleasure and pain… Then, as lead singer, it’s up to Saori to get the band past Kijima, the shady don of the entertainment business. Using his position to fulfill his wildest desires with all of the hot new pop idols, he’ll never even consider giving anyone a chance at a big break until after his carnal desires have been satisfied. Saori’s mother knows this all too well; to get Twinkle noticed, she’s already given in to his erotic demands.

The story of a pop idol and her dear friend (who doesn’t care much about other girls) and always pays attention to the idol – who in turn, is harassed by her manager. One day they are about to have sex in the dressing room when the manager finds out via CCTV. He gets in the room to stop them and takes advantage of the situation.

His whole life he has been a failure, but he still wanted to try and teach students anyways. Turns out even a failure can land a hot schoolgirl as long as he has the equipment she needs!

NOTE: This is a 3 part series with the same opening scene, the ending scene features different costumes and action.

When he won’t come down for lunch, though, she goes up to his room and catches him masturbating to some hentai. Then she finds a book about having sex with women, so she volunteers herself so he can learn and experience the real thing – but it’s not complete until she puts on a costume!
