A/N: Hey, this is my new story. Hope that you like it. If you read my other stories, I am so sorry for taking so long to update. My laptop decided to go crazy and take a shit on me and now I have no computer, unless I use the ones at school or at my grandparents (like I am now) and I don't see my grandparents very often, and I'm hardly on the computers at my school. I should be getting a new laptop soon, if I can't get my old one to work. Disclaimer: I don't own One Piece or any of its characters. How ever, I do own Alex (yea me lol). I have no clue if there is a technical term for any of the weapons used by Alex or any of the One Piece characters. If there is, please let me know so that I can use them correctly.

Chapter One: Luffy has a Sister?

Nami sighed as she watched the three guys on the Going Merry argue.

"No, I mean it. I know someone who you would love to fight against," Luffy sid to his first mate, Zoro, as Zoro shook his head.

"Doubt it." Zoro watched as Usopp stood up and glanced out over the water. Nami looked as well and smirked as she saw land approaching.

"Land, straight ahead guys!" Nami shouted down as Luffy and Zoro stood up as well.

"I'm getting a bad feeling about this island…" Zoro trailed off as he gripped his swords tightly at his side, staring at the island as they approached it. Luffy glanced at the swordsman out of the corner of his eye before nodding in agreement. Soon the Going Merry docked and the four members were walking into the town. Luffy and Zoro couldn't shake off the feeling that something was going to happen soon.

"Get back here!" A male voice rang out as a girl with two swords and what looked like a staff ran past Usopp, scaring the poor sharpshooter. Glancing at Luffy, Zoro watched as the girl looked behind her to see the men, all roughed up, still following her. She glanced at Luffy and smirked, causing Nami and Usopp to glance at each other. Luffy sighed and shook his head as the girl stopped next to Zoro, causing the green-haired man to stiffen.

"Get ready for some entertainment," the girl said as Luffy shook his head and glanced at the girl before facing the men that were chasing her.

"You owe me big," Luffy stated as he pulled his arm back.

"So, I'll buy you some meat." The girl replied with a smirk as she pulled the staff off her back, revealing that it was actually a double-bladed sword hilt. Placing the double sword in her mouth, the girl then drew the two swords that were resting on her hip.

"Gum Gum Pistol!" Luffy threw his arm at one of the men, punching him in the face. "Go!"

"I'm on it." The girl jumped on Luffy's out-stretched arm and ran down the length of it. "Four sword style, Dragon Strike!" All the men fell to the ground and the girl jumped off Luffy's arm.

"Wow" Zoro watched as the girl walked over to them again.

"Haven't done that in a while." The girl smiled as Nami and Usopp gaped at her. "What? Is there something on my face?"

"No. That was amazing! The only person I know that can use a multiple sword style is Zoro. And yet you can do a four sword style…" Nami trailed off as the girl grabbed her four sheathes.

"I can use an extra blade, so what?" the girl glanced at Nami before placing her double sword on her back again. "Thanks, Luffy," she called before walking away. The girl got about five feet before Luffy tackled her.

"What makes you think that I'm going to let you get away?" Luffy demanded as he and the girl struggled for dominance in the fight. The girl sighed as she kicked Luffy in the leg.

"Cause you know that I can kick your ass and will do it ten times worse than usual if you don't let me go." The girl rolled once Luffy jumped off of her and stood up.

"So? Nami and Zoro can kick my ass too. Nami does a good job at kicking my ass about the same amount as you." Nami and Zoro raised an eyebrow as they watched their captain argue with this girl that he apparently knew.

"So? Luffy, please just tell me what you really want." The girl watched the rubber man as he stood up finally.

"I want my sister on my crew. Just like we had dreamed of when we were kids. Remember that?" Luffy grinned as the girl and his crew look at him.

"What!" The girl shouted at the statement that he wanted her to join his crew like they had dreamed of.

"What!" Name, Zoro, and Usopp shouted at the same time as the girl, but on the fact that Luffy had a sister.
