In the world of One Piece, I meet the best of you. I heard that the previous goddess was a partner with the Pirate King. Now that you want to be the Pirate King, can I be your partner? You are the stupidest among the four of us, so I have to watch over you for Ace and Sabo. You have to take me with you on the boat that goes against the large waterway, because I am the youngest and can only get on your boat. Hey, the four of us must do what we agreed to do, and we must not die, my most important family members.
Highlights - all members are friendly, no male protagonist
Intention: All persistence will have results
