Miku hates going to school. There are always gropers on the train and today is probably the worst day of all. Four men’s hands grab her and climb up her leg into her underwear, yet she is too terrified to muster the courage to tell them to stop. Just as the groping gets unbearable, suddenly a woman calls out to her. It’s a middle-aged woman who Miku often sees eating snacks on the train. While usually Miku is annoyed that she eats food on the train, today she thanks the heavens for her intervention.

The gropers flee at the next stop and the woman takes her to a cafe. She buys her a hot, sweet drink and Miku finally manages to calm down. Once she’s regained her composure, the woman offers to drive her home. Miku is unsure, but agrees.

However, when she gets in the car, Miku realises it’s too late. The doors lock and the horrid stench of sweat surrounds her as the men from the train entrap her. The woman tells them not to kill her just yet—they need to have their fun first.
