A while later, the crew lands at the island docks. The island is a mixture of dry and wet, red and blue, and black and white everywhere. Even the people. Luffy walks up to an old man dressed in red.

" Hey could you tell us where to find the Yin Yang fruit?" He asks.

The Yin Yang fruit? I don't know why you be wanting it but I'd go find and ask Akane and Aoi where it be. They found it." The old man tells him and walks away.

"Akane and Aoi?" Luffy looks around.

"Hm, how ironic." Robin says aloud.

"What's ironic?" Nami questions.

" Akane means bright red and Aoi means bright blue." Robin answers. "And those names are opposites just like this isle."

"Yeah, you're right." Nami nods. "Uh, where did Luffy go?!"

"Could you tell me where to find Akane and Aoi?" Luffy's voice asks.

"See that hill back behind those trees? Go over that, follow the path, and you'll be there." A man's voice replies. Luffy walks up to his crew with a huge grin.

"Ready to go?" He questions.

"As ready as we'll ever be." Zolo says. Luffy marches off towards the hill with his crew in his wake. They go over the hill and follow the path through a forest of red and blue. Soon they reach a small cottage with purple sidings, blue trim, a red roof, and black and white shutters, and a grey door.

"This must be their house." Luffy says aloud, looking at the small home. "I wonder what they're like."

"Well, seeing as how these girls have found this fruit, and one has probably eaten it." Robin replied. "then there's no telling what… we're…"

"Hey. You no good looking scoundrels, what do you think you're doing on our Isle?" An extremely agitated blue haired girl demanded outright, emerging at a sprint from the cottage.

"Akane, you don't have to be in that bad of a mood towards our guests, even though I know you're already roughly mooded as it is." A gentle looking red haired girl told the blue haired Akane.

"Shut up, Aoi." Akane shouts at Aoi with her hands balled in fists, ready to charge.

"Whoa. Whoa. Don't start fighting just because of us." Sanji states to calm Akane down. "If we are not wanted here, then we'll just leave."

"No we will not leave." Luffy denies. "Not until I find the Yin Yang fruit."

"If that is so, then we are sorry to tell you, but you are looking in the wrong place." Akane, rather coldly. And Aoi, sweetly, tells them simultaneously.

"WHAT?!?!?! Why not?" Luffy shouts in disbelief at the two girls.

"If you must know, then we will tell you." Akane replies some what mysteriously and coldly.

"There isn't a Yin Yang fruit anymore." Aoi finishes plainly and warmly.

"Whaaaat?!" Luffy shouts.

"That's right," Akane tells him gruffly. "We ate it."

"'We,' you mean you were one person until you are that fruit?" Usapp asks in disbelief.

"No silly, we split the fruit together. I ate the Yin half." Aoi giggles.

"And I ate the Yang half. Now go!" Akane shouts in anger.

"Akane calm down…"

"I hate it when you tell me to calm down!" Akane screams at Aoi who looks at her with a calm smile.

"Now, now, just because you have the opposite mood from me doesn't mean you get to make yourself angrier."

"I'll show you angry, come here!" Akane begins to chase Aoi around the yard. Aoi trips over a rock and lands on her chin and the crew notices that when she grimaces Akane smirks. Akane jumps on Aoi and punches her. Aoi only blocks Akane's attacks and her face is completely devoid of emotion. Akane is pulled off of Aoi by Zolo, Sanji, Usapp, and Luffy while Aoi is helped up by Neco Robin and Nami. Aoi holds her swollen cheek and winces. Akane smirks though she still struggles in the guys' grasp.

"Put me down." She demands.

"No way, have you seen what you just did to Aoi?" Sanji asks her.

"Yes, and I do feel bad about it, but sometimes I can't control myself. I did eat the Yang half of the Yin Yang fruit."

"Hey guys, thanks and all, but I'm used to it pretty much. Its been this way since our father died. He used to keep up 'happy' sorta." Aoi states a little watery, from talking about their father.

"Aoi, they don't need to know about Daddy. Its none of their business." Akane claimed with an evil smirk.

"Akane, drop it. Its been a while since we've buried him, and we haven't coped well with his death, so lets do something to get it off our chests."

"No, these people are complete strangers."

"You're so stubborn."

"So sue me."

"I'll do something better." Aoi waves her right hand and a small thunder cloud appears over Akane's head and starts raining.

"Oh, so that's how you want to play, huh?" Akane waves her left hand and the sunlight gets brighter and stronger over Aoi.

"Okay, you two, stop!" Zolo stands in between them and the girls stop.

"For sisters, you sure do fight a lot." Nami comments. The girls look at her. Akane gives Nami a pointed a look while Aoi has an amused look.

"They each ate separate halves of the Yin Yang fruit remember?" Robin reminds Nami.

"Hey, I have an idea!" Luffy says. Everyone looks at him in confusion. "Why don't you two join our crew?!"

"Whaat?!" The Straw Hat crew stares at him in disbelief.
