Escaping from the exploding starship, Iria lands on the planet Taowajan - the fate of Gren and Bob still uncertain - and must find her way home. However, Zeiram was not destroyed in the explosion, and crashes into the city's slums - where he begins a program of "urban renewal." As the authorities turn a blind eye, only Iria, and her streetwise sidekick, Kei, can halt his rampage. But who is the mysterious voice over Iria's communicator?
