Rei is well enough to go back to school. She confronts Fukiko, but is made docile with a few words. Tormented, she retreats to the clock tower and takes a lot of drugs. Looking for Rei, Nanako enters the clock tower, and finds her delusional and hallucinating. Believing Nanako to be Fukiko, Rei reveals that Fukiko had made a pact of double suicide with Rei when they were younger. She attacks Nanako with her knives, thinking that she is Fukiko and has arrived to fulfill that pact.
