Before the events of the story, Jay was abandoned as a baby and found by an assassin named Solon. Over the years, Jay began to train under Solon in the art of assassination. Jay was beaten and punished whenever he tried to rest or show any emotion. One day, Jay, Solon and his men were sent to the Legacy, but another group of men were waiting for them, annihilating every one of Solon's men. With only Jay and Solon left to be killed, Solon then abandoned Jay as a decoy and escaped. Jay was attacked, but he managed to escape as well. Jay then wandered around the Legacy, weak and on the verge of death, he eventually collapsed in front of the Oresoren Village. Three young Oresoren, Quppo, Pippo, and Poppo, found Jay and took him back to the village. Within the Oresoren Village, Jay was silent and never talked to Quppo and the others, but eventually he grew fond of them and opened himself to their friendship. Jay eventually decided to make the Oresoren Village his new home, leaving his old life behind.
