Spoiler Warning!! [+/-] Show/Hide Synopsis...
Rena calls the school and is able to get the teacher outside before entering and taking all the school kids hostage, though Keiichi is the lone one not tied up. She begins to negotiate with Oishi about the conspiracy she believes is related to the Sonozaki house and the scrapbooks that Takano gave her before she died. After Keiichi returns from giving the remaining scrapbooks to the police, he finds Rena pouring gasoline around the classroom, calling it insurance. Rena wrote a letter to Oishi in the scrapbooks detailing her terms and telling him about a time bomb that she set up in the school set to go off at 7:00 PM. With Keiichi in possession of an earpiece to communicate with the police, they describe to him the situation and he goes to try to find the bomb. Rena, however, finds him in the process and almost stops him, but Rika steps in, enabling Keiichi to continue the search. Satoko then helps him by telling him that the bomb is most likely on the roof and he heads there with only seconds to spare. Keiichi manages to disarm the bomb, but Rena meets him up there and they have one last fight on the rooftop. In the end, Rena wins but realizes what she has done and is able to stop herself from killing Keiichi.
