Aimi Sakagami (Ai Sayama) was standing on the edge of a building on the roof of the school building and on the railing when the graduation ceremony arrived. In her hand, in addition to the diploma she was presented with earlier, she is wearing a red tie. This tie was given to her by a fat, bored businessman named Ai Kamiyama. Aijimi was kidnapped by Kamiyama and was raped in this man's apartment, losing her virginity in the process. Furthermore, the act was performed by whipping her while she was chained by the neck.
