When a scientist attempted to create a vaccine, they instead created a deadly virus known as the Aiko virus. This virus caused a zombie-like, vampiric disease. Infected individuals appeared human but hunted humans like vampires. They craved human flesh and blood, feeding like ravenous wolves. The virus originated with the "Aiko" plant, initially believed to cure cancer, rabies, and other diseases, but something went wrong during testing. Inhalation of the virus caused violent symptoms: red, purple, blue, orange, and yellow eyes; blue lips; yellowish-pinkish skin; and blue spots.
One fateful day, something went wrong during a test conducted by Dr. Issako Neko. A patient descended into madness, turning violently aggressive.
