Daughter of the Revolution
Monkey D Luffy, daughter of the Revolutionary Dragon has been apart of the army since she was old enough to fight. She shares her father's dream of fighting for what she believes in, but often has a hard time doing things in secrecy. In this story, Luffy is a female and never met Shanks and now has a different devil fruit. (Sequel/Prequel coming soon)
