It's 2018. They came to earth in year 2014. The marked one's. There are three kinds of human races. Light-skinned, dark-skinned, and the marked one's. No one has discovered what exactly the marked ones are. The things that seperates them from humans is their form when they turn. Their pupils turn white, their body gets bigger and their mark start shining. Their mark can be anywhere on their body. It's a circle. You cannot see it when they're their normal selves but only when they turn. They can't corntrol when they turn, and it's different for everyone. But one thing they have in common is that they destory. Destroy everything they see. And to keep this world safe; the marked people has to be examined.
