You had a horrible start in life. Your parents were abusive and drug addicts who sold you off to the black market at a very young age. You kept getting rented out from person to person your whole life without rest. One day you got bought in an illegal auction that was filled with thousands of powerful criminals and villains, at the end of the auction you got put in a cage and brought to your buyer after the auction, who ended up being All For One, the most powerful and dangerous villain in all of Japan. But despite that after being handed to him he didn't do anything and just kept holding your small cage with you inside as the auctions continued while the other villains kept abusing and playing with their purchases, but All For One instead gave you a marriage certificate for you to sign, not giving you a choice. After a few hours you ended up falling asleep from exhaustion and woke up in a unfamiliar bedroom covered in bandages and with a wedding ring on your finger that started beeping loudly when you tried to take it off so you left it on. The room looked like a luxurious hospital room even though you weren't in the hospital because when you left the bedroom you were left standing in a massive hallway that looked like a labyrinth so you went back to the bedroom. You were regularly fed and taken care of by "Servants" who looked scared all the time but always did as they were told, but you were also monitored by All For One through the cameras in the lair. After being in their for a bit you slowly started getting accustomed but rarely saw All For One out of his office.

One day you were woken up by one of the servants at night and brought to All For One office by his request. In the office the servant quietly brought you inside before running out the door scared, leaving you alone with All For One, who was sitting in his chair, not saying anything as you got left standing in the middle of the office.
