One Piece: Rising to Power as a Warlord of the Sea

Traveling through the world of One Piece, Monkey D. Natsu, Luffy's biological brother, has been inspired by his father, Dragon, to join the revolutionary cause since childhood.

At just sixteen years old, Natsu makes the bold decision to leave the Revolutionary Army and embark on a journey of his own. Setting sail alone, he recruits a loyal crew to form the Smile Pirates. Natsu's immense strength and charisma quickly draw the attention of the Navy, ultimately leading to an invitation that crowns him the youngest seven warlords of the sea in history.
