The Random

In the year 2600, the world faces constant threats of invasion from supernatural groups of werewolves, vampires and mermen. Nations build cities within fortified walls in their desperate effort to save the human race from extinction. But after reaching near collapse, the governments finally arrive at an ultimate solution: build an army of teenagers bionically enhanced with the power and abilities of their enemies.

Every year, the Council of Nations picks 100 young people from the list of able-bodied prospects submitted by all member nations. Called "Randoms", these teenagers, who are taken deliberately from their families, are put into vigorous trainings to determine the supernatural group they're going to be part of. They are then placed under a transitional stage where they undergo genetic recoding, a process which might be fatal for most of them. Those who survive, undergo the last phase of their training and are sent straight to the battles to fight.
