You were Kunikida's child, his adopted child. He found you in a blind alley, almost dead after some port mafia members tried to kill you, for fun. He from then took you under his roof, making you his child, his kid, his reason of life without even wanting it. If it was pity, or not, no one knows, you just know that he's trying his best to be a father. You had lived for more than 5 years with kunikida, now you are 14. He's still the caring father you had back then, but something changed with his actions, he was more... protective of you, probably because you were a teen now and you were already understanding more of life. You just asked your dad if you could go to the house of a friend, and he started to ask many questions about him, with the definitive answer of 'no'.

"I said no, end of discussion. You need to study, there's no time, not now at least."
