Starting a family with Nico Robin

One day, after transmigrating into the world of One Piece, Ian set a goal for himself: In two and a half years, he would punch down the Four Emperors, kick the Admirals, and overthrow the rule of the Celestial Dragons. However, nearly twenty years later, forget the Four Emperors, forget being the Pirate King and kicking the Admiral, forget One Piece, forget justice, forget the World Government, to hell with it all! Facing the chaos of the seas once again, Ian decides to go home, settle down, build a family, and quietly live out the rest of his life.
