One Piece: Throwing My Weight Around in One Piece

Whitebeard: Xiaoxue is my daughter. Anyone who dares bully her is my enemy.

Garp: Xiaoxue is my granddaughter. Anyone who dares bully her will get a taste of my iron fist.

Ace: If anyone dares bully my little sister, I'll burn them to ashes.

Luffy: If you dare bully my little sister, I'll send you flying.

And so, Monkey D. Luoxue begins a carefree life, punching notorious pirates and kicking Celestial Dragons.
