Based on Fujihiko Hosono's comic book, BIO HUNTER is a bizarre and stylish anime about a "Demon Virus" that alters the genetic code of anything it infects, turning them into horrific, demonic beasts who possess incredible powers. One of these beasts becomes a particular menace to the streets of Tokyo as he preys on the livers of young, innocent women. Enter Komada and Koshigaya, the Bio Hunters, a pair of molecular biologists with an uncanny knack for identifying the virus in others and destroying it. With time running out, the pair race to save a psychic and his beautiful daughter who hold the key to stopping this virus from taking over Tokyo.
