Shiori had no friends at school and was like a ghost, eventually becoming a shut-in who skipped school. One day, she was attacked by her homeroom teacher during a home visit and received intense face-fucking guidance. Her innocent throat-virgin reactions—trembling, having no tolerance, and showing rejection—are incredibly realistic, stimulating a man's sadistic side. The next day, Shiori attends school for the first time in six months. On her way, she is pulled into the shadows by her teacher for more deep-throat guidance. Forced to hold a ball-gag dildo under her mask, she undergoes "ira-mask" torture. At school, she is called out by classmates after hours who say, "We'll be your friends and play with you," leading to a gang face-fuck. Furthermore, she is "played with" through stomach punches, kicks, slaps, water torture, and having her bare face exposed. Despite the series of brutal, heart-wrenching acts that should be painful, the previously lonely Shiori convinces herself that they are the first people to "really look at her," creating an illusion of love. Combined with her innate masochistic nature, Shiori gradually awakens as a masochist. "This crazy world is where I belong..." (Shiori)
