One Piece: Am I becoming Wang Luffy’s sister?

Story of: One Piece: Am I becoming Wang Luffy’s sister?

The pirate king Gol Roger, who possesses the wealth, fame, and power of the entire world, puts all his treasures in the "Great Line". With the words "one piece", everyone sails there to pursue their dreams. The world begins to welcome the advent of the Great Pirate Age. When she opened her eyes and was reincarnated into the world of One Piece, Itsuki became Luffy's sibling sister. She only knows the first small part of the plot, and she doesn't have any superpower system nearby. How can she survive in the world of pirates? Until she saw the vast ocean, Itsuki, who lived inland in her previous life, laughed out loud. The clear sea water and soft sandy beach can not only catch sea adventures, but also eat unlimited seafood. Tears of dissatisfaction appeared from the corner of the mouth. It was very beautiful.
