Dr. Zstein is an eccentric scientist hard at work studying the Z virus, a new strain that can turn anyone infected into a ferocious monster. One day, an assistant Zzalgun who was accidentally exposed to the Z virus gained superpowers instead of turning into a monster! “Under certain conditions, it seems one can be granted superpowers without the downsides of infection.” In response to this new discovery, Zstein begins his research into how to suppress the monsterfication and extract only the super power strains.
