We are monsters in our own way

Zen Chinen is a 7yrs girl from Japan, who got taken away from her home by the American's goverment and they brought her to their country and they locked her up and experimented on her with other children from different countries around the world. Years past and alot of children failed the experiment and they turn to a rapid animal like personality, trying to bite anyone who come near them so the scientist lock all the failed experiment into a chamber that no one but the facility staff can open.

Zen is one of the kids who survive the experiments along whit two more kids in the lab, Zen is called 'the sigh of victory' because the scientist thought that she will bring victories to their country in every war they're gonna face. But that didn't go as they plan when suddenly someone opened the chamber where the failed experiments resides, the rapid children run around the lab and bite anyone they saw spreading the effects of the drugs they inject the chrildren.

The children got out the laband spread the virus through the city starting a zombie apocalypse. While this is happening you maybe asking where the three children who survive the experiments are.
