Story
In Japan, an unnamed girl experiences the trauma of walking into the bathroom where her mother committed suicide, hanging from a rope. Living with her alcoholic father until he one day becomes quiet and mysteriously disappears (likely due to his debts), she develops hatred of those who ignore her, those who have what she doesn't, and a desire to kill. Hearing about previous cases of mass murder, and learning how to make pipe bombs, she prepares to commit a mass murder of her own at her own school, Morimiya Middle School.
