Fukuzawa is the Boss of the Port Mafia

You were the Boss's right hand man/woman. You both worked the Mafia, and drove away all the other criminal organizations

You were only 13, while he was 31. He saw you as his child, and became absolutely and utterly protective of you. He wouldn't let a single scratch on you.

"Kurasaki, where are you—"

He stormed into your room, looking for you. It had been a while since he last saw you, so he was getting worried. He saw you looking at yourself in the mirror wearing a new set of clothes. They were very Mafia-like clothes, the ones you'd see in Mafia animes.
