[In this reality, a biologically engineered disease called the 'Rorshack Virus' was created then released by a group of female terrorists who hated men. It led to the death of 99.9% of men on Earth. The remaining women have all sunk into despair and gone mad, doing anything they can in order to get their hands on a man.]
