Luffy x Demon! Reader

Fight!

Last Time On One Piece~

"Hello (Y/n). "You!" You growled and stood up clenching your fist.

____________________________________________________________________________________

"I can't believe a fragile little thing like you, could still be alive after all this time." The women said to you as she pulled out her sword ready to fight. (picture above)She then looked down at Luffy and gave a devilish smile. You then went into first demon stage (i'll explain later what the stages are) and stood in front of Luffy to protect him. "(Y/n) who is this women?" Luffy ask a little bit pissed. But before you could answer she flew down and spoke. "How about I answer that for you. I am the person that will make humanity bow before me and unleash a army of demons to turn all human life to my very own demon slaves." "No that won't happen!" you yelled and you dashed towards her. But she quickly dodged it. You then took out your sword, so did she. You ran towards her incredible speed. Your swords clashed together sending out little sparks flying.

She was going to blast you with her power but you flew up into the sky. "Why? Why are you doing this?" You yelled. She went flying towards you and once again your swords clashed. "I'm doing this because I know the true power of demons I know what they are capable of. UNLIKE YOU!" She yelled as she rose her sword, but before she could hit you Luffy stretched his arm and grabbed you and ran as fast as he could.

Your Attackers POV (short)

I watched them leave but i didn't decide to follow instead I just flew away but I stopped and yelled any further out of my sights "OH DON'T WORRY (Y/N) I'LL BE BACK SOON!!!!!"

Normal POV
A soon as you were out of her sight you both hid inside a cave. It was dark but you used you light ability to light up the cave. "There now we can see." You said to yourself. "(Y/n) who was that?!?" You just looked down and sighed you didn't want Luffy to get involved. But it was too late for that now.
"(Y/n)! Who was that?" Luffy was irritated but also worried about you. "Luffy that was my sister (S/n). She came back and I don't know how she found me but all I know is that we have to defeat her at any cost." Luffy then nodded and spoke "I don't care who she is all I want is for you and your sisters and friends and my crew safe from what ever she is." "I understand. But she isn't getting any where near your crew or you Luffy."

"What are you saying (Y/n)?" Luffy asked a bit worried. "I'm saying that your not going to fight her Luffy. Just me, my sisters and Akala and Sky." "No (Y/n) I told you i'm coming with you!" "Luffy I never said yes that you could come." You said with a serious tone. "I don't care if you did or not i'm coming with you and that's final!" "No Luffy I don't want you to!" "(Y/n) I need to make sure you don't get killed! Please just let me-" But before he could finish you stood up and ran out of the cave. "(Y/n)!"
