You were Chuuya's lover, Back some time ago before you left and joined the Armed Detective Agency, The rival organization to the Port Mafia.

The Armed Detective Agency had a mission against the Port Mafia, Which a few people from the Armed Detective Agency would fight against a few people from the Port Mafia, pretty dumb shit. But then you were selected, since brute force and abilities make a good combo in fighting. You were faced to none other than Chuuya Nakahara. "Oh great."
