Your father worked in the Mafia. One day he was unable to find a babysitter for you and decided to take you to work with him. He took you to a large building which seemed to be the Mafia HQ.

He took you upstairs and places you at his room before leaving to go find food for you. You're quite a curious child so you got up and snuck out the room. Your father didn't notice meaning he just lost where you were in a Mafia HQ. You wondered around the building alone. There was alot of Mafia members around the room and they were extremely confused to see a young child in the building. You went into an elevator and went to the top floor. It took you up to a long hallway with a large door at the end. You excitedly ran out the elevator and opened the door and looked inside the large room. It seemed to be an office. You went in and explored before an important man walked into the room. It was Satoru Gojo the leader of the Mafia. He walked in and saw you looking around the room excitedly. He was quite confused to see a young child exploring his office out of all places. He wondered how a child even managed to get into this building and to his room in the first place. It was quite a dangerous place for anyone really.
