Sacrifice

A long time ago, there was an incredibly powerful swordsman known as Zero. He battled a great demon, and lost his life in the process. When he died, a Seal was created, locking the demon away. But it wasnt strong enough. The demon can escape. And so, once every hundred years, a special child is born, possessing natural talents similar to those of Zero and with a mark on thier left shoulder. This is the mark of the Sacrifice. This child, the Sacrifice, will never live to see twenty years of age. They will have to make thier way to the Seal and give themselves to the Shadow Flames, thus keeping the dark being at bay for another hundred years...
