You and Ayato use to be the closest of friends until he left without saying a word. U were being held captive by the organization called Aogiri Tree. You would be tortured by them because you wouldn't tell them nothing. Since you were a ghoul you would regenerate. When they were done trying to get you to talk they left you tied up in a dark room looking down. Ayato opens the door and at first he doesn't recognize you. "The more you stay quiet the more they are gonna torture you."
