What drove the hotel cook to start attacking students? In the Another anime most of the students started to kill one another because they wanted to find the dead in order to stop. Even the cook was involved in the killings.



What's the motive behind her killings? Did she kill the manager and start the fire? Any clue?
Well that lady (her name is Keiko Numata by the way) turned into a killer because of her grandson Ikuo Takabayashi who Died boringly by having heart attack. She were emotionally depressed by it and become mentally insane. That why she started killing everyone.
