The weaknesses of the people who live in conflict with the self-life of the people, and the desires of the people who are so greedy, are the two of them.

Hiko, a strange form known as a demon beast, began to appear, known as a demon beast, who is in conflict with his own personal life.The source of the source is still unknown.Other than being nocturne, I don't know any of the ecology. As the police were hushing around to combat the devil's beasts, there have been rumors that Makoto is silly whispering. A duo girl in a mysterious suit destroys a demon beast. This is a ridiculous fantasy and a laughable street story, but... in the first place, even a demon beast was initially thought to be an idiotic fantasy.So perhaps??  The protagonist is an introvert and has few friends and is a frustrating day.He had a contrasting younger sister and childhood friend. My younger sister disliked the unfavourable protagonist because of her overbearing personality.Her childhood friend is well-liked by everyone and has excellent grades, and she is an impeccable girl who also serves as the class president, but her attitude towards the protagonist is somewhat pitiful, and she always falls in misery. The protagonist eventually begins to feel evil in the two of them, and is indulging in the fantasy of turning him into a meat toilet who listens to whatever he wants. One day, I was walking around the park at night and heard a woman scream.Out of curiosity, she heads towards the voice, and finds a girl in a mysterious suit who is defeated by an unusual figure and desperately resists.As she watches the scene from behind, the girl's true identity is finally revealed.His true identity was a childhood friend. The protagonist, who happens to be present, threatens to reveal his true identity and exposes his usual frustration.He is defeated by a monster and is raped, and his sensitivity increases, and he climaxes as he is raped by the protagonist.From that day onwards, the days of training to turn into a sex slave begin.However, in the process, he learns that there is another transforming heroine.
