Synopsis
Born to human parents, an apparently normal child might at some point between childhood and late adolescence experience a process called 'breaking out' and develop special paranormal abilities. These abilities include psychic powers such as telepathy, telekinesis, and teleportation. However, their psychological make-up prevents them from intentionally killing others.
