In a distant future, Earth is struck by a meteor carrying a dangerous pathogen known as M34. This virus has the ability to transform humans into savage beasts, annihilating most of the population. In response, governments establish specialized agencies to combat the deadly threat. Among these groups is NOA, whose soldiers are implanted with nanomachines that enable them to fight against the infected. However, when the virus evolves and becomes even more formidable, NOA finds itself powerless to stop it. Now, the only hope for humanity lies with a 16-year-old girl who possesses the unique power to defeat M34 and save the world from certain doom.
