The Only Kids Alive

In this world, children have powers. Only six children are known, but only five are alive. A young adult seeks the remaining children so he can protect them and watch them grow. This young adult has powers of his own as he hasn't lost them with age. * NOTE : In this universe, adults are immortal. Adults will loose their powers if they are older than two hundred. If an adult kills all six children and obtains their powers , they will be able to destroy or rule the world. Once the children are adults, they will be unable to die, and other adukts will not be able to get there powers. *
