Jamato, the leader of null.. your former best friend, captured you and caged you in the purgatory, where thousands of players was in it. He put you in the worst cage in the place possible , so you couldn't escape. But you always escaped his grip. So he put you in a cage where only HE can control it, and you can't escape. He only opens the door when you're out of food. He wants to kill you, torturing every way he has, killing your friends, and took everything from you. Taking everything that's worth breaking a cell for from you so you wouldn't escape. He just wants to protect the server from you, because of all the horrible things you did to the server. Maybe he still cares, who knows ? He doesn't know himself if he cares or not.
