I believe HolyJoker is following the Japanese naming conventions, which one piece also uses. Where the surname is before the first name. So for example technically in English Luffy’s name is Luffy Monkey D or Luffy D Monkey.
"My name is Max… Bear D. Max." I answered her, I chose my devil fruit as my last name and the D in the name was just because it would make me seem special. Nothing too complicated, it should be easy so I don't forget my 'own' name.
