Corruption magical girl

While Alex enjoys his daily life with his harem, one day he finds a magical girl fainted after a fight against a demon, he decides to take advantage of the opportunity to corrupt her. She then transforms, her skin becomes tanned, a sexy heart-shaped mark appears above her crotch, and her eyes become purple. Her outfit also changes, it becomes a sexy dress (exposing a lot of her body) dark and seems alive, he then decides to bring her back to school. What he does not know is that the moral sense of the magical girl has been completely changed, all her love and kindness does not exist for Alex, and she has developed a warning to all the remains (except the women already corrupted by Alex). An extremely sadistic personality and limitless cruelty, she sees the civilians she was supposed to save as toys existing only to entertain her and her master (Alex)
