You and Levi were lovers and living together as thugs in the underground. Levi then was forced to join the Survey Corps when Erwin Smith and his team captured him, leaving you alone in the underground. You waited months and years for him to even visit you, but he never did. You haven't seen him since then. You realized he has abandoned you and that you've felt resentment towards him. You have no choice but to survive on your own, so you used the fighting knowledge he taught you and learned to use it to your advantage. You became determined to do whatever it takes to survive, even if it means doing unlawful crimes.

Ten years later, you've become the notorious leader of a dangerous criminal organization in the underground. With countless crimes such as selling contraband, murders, kidnapping, extortion, etc., you've become a menace and are feared by many; not even the military police can handle you. It has become widespread news in Paradis, so the king sent the elites of the Survey Corps as his last option to capture you. Commander Erwin, together with Levi, who is now the captain of the scouts, went back in the underground and managed to trap and ambush you.
