Spirit!

It was the seventh century, when the japanese army of the samurai was founded. Back then many soldier fought in a war called „Fuun“. The local warriors were known as spriritual fighters. They followed a self-proclaimed relief and chose their own way of life. Through a ritual humans created ten body independent powers called „Meta-Spirits“. They were created as little energy cores that a single human could absorb. So it happened that ten strong warriors got one Meta-Spirit each. They increased their physical strength a bunch and gave them powers, that they´ve never had before. So the war continued for years. All of the samurai were beaten towards the end of the Fuun, except for ten of them, the Meta-Spirit users. They began to fought and even kill each other little by little. The last survivor collected the other nine Meta-Spirits that were left behind. But his body couldn´t take all of this power so every single cell of his body decayed. So all ten Meta-Spirit users were killed. The humans saw the created powers as a threat and constantly ignored them. The Meta-Spirits began to wander through Japan independently, and like some kind of virus they have thrown parts of theirselves off. And so they infeceted the human cells, that paranormally mutaded and gave them unique powers. Those paranormal mutations were called „Spirits“.
