After 9/11, Nao’s classmates are nice to her for awhile because of her connection to America, but things soon change. In October, Nao gets her period again after not having it for almost a year. She realizes that she has her period at school and goes to the bathroom. While she is in the bathroom, some of her classmates stick a phone over the walls of the bathroom stall and take pictures of her. Nao pulls up her skirts and backs into the corner of the stall. She opens the door to try to escape, but Reiko blocks her from going out the exit. The girls grab her and force her to lie face down on the bathroom floor while Daisuke films. They tie her hands together and tie her skirt over her head so that she can’t see anything. While holding her ankles, the pull off her underwear, which are covered in blood. Nao hears them talking about who will rape her first. They decide to make Daisuke try, but he is too scared to do anything. The kids then notice that Nao has stopped moving and decide to run away, leaving her tied up in the bathroom.
