In the year 2021, mankind was brought it's knees by the sudden disease of Gastrea, a parasitical virus, and is forced to live within Monoliths, which are created from Varanium: a metal that is able to subdue Gastrea. Soon, the "Cursed Children", children born with the Gastrea virus who are able to control it, which gives them superhuman abilities, are discovered. Civil Securities are formed to specialize fighting against Gastrea, operating with the pair of a Client, who are cursed children, and a Contractor, serving to lead the cursed children and keep their powers at bay for the people that resent the cursed children. It's been 20 years since they've appeared. Right now, it's the year 2041. ~~~ "Honestly, I've called for the Civil Security about half an hour ago, and they still haven't shown up? This is a life and death situation here!" The detective standing in front of a crime exclaimed as the surrounding police officers had already gone inside of the building to scope out the area.
