Since ninjas never talked about their missions and history very little history remains. It is believed that the ninja way started in Iga Japan with a young boy. It is believed that the boy wasn't allowed to see his dying by a monk. When the boy's father did die the boy cursed the monk. So the boy faked sick so that the monk would take him in. Each night he would surve the house to see we're the monk slepped then one night the boy tooled the monks sword and killed him. He then escaped the house into the night. This is the first recorded ninja activitity. As more ninjas came into Japan they started to form clans. The biggest being the Iga and kōga they both trained ninjas for special jobs. The ninjas were then hired by diamyos (a powerful feudal lord) between 1485 and 1581.
