Red haired beauty

What if Shanks had a sister? What if she fell for Mihawk? What if she's the reason Shanks and Mihawk started their duels? This story follows Scarlet, the twin sister of Shanks. it's kind of set before and during Luffy's time frame. but it will also not follow the live action perfectly as it's about my OC and not Luffy and the gang i may add some stuff from the anime as well as the live action isn't finished yet.
