Talk = "Onii-san"

Thought = Onii-san

Recap:

"Ace! Yuna!"

"You never change, Luffy" Ace smirked.

"It been a long time." Yuna smiled.

"Ace. It Ace! You guy ate Devil's Fruits?"

"Yeah, the Mera Mera (Flame Flame)Fruit."

"But my power isn't from the Devil's Fruit" Yuna said.

"Anyway, we can't talk like this! We catch up later! You guys run for it!"

"We'll keep these guys busy! GO!" Yuna said.

"Let go!"

"But Luffy!" Nami shouted.

"Who the hell are they?" Sanji finished.

Both Ace and Smoker started to stare off again.

"I don't get it. Why did you both help Straw Hat?" Smoker asked.

"Having a younger brother who's a bit on the slow side makes his older brother worry." Ace said.

"And the younger sister has to support her second older brother anyways."

"What do you mean, 'younger brother and second older brother'? That means ….."

"I let you do the fighting, Ace." Yuna said as she move a side.

"Move!" Smoker growled. "Portgas D. Ace!"

"I don't think so." Ace rejected as he and Smoker started fighting.

"Wait, Luffy. Just who are they?" Nami asked.

"Are they someone you know? Luffy-san." Vivi added.

"Yeah!" Luffy grinned "They're my brother and sister."

Chapter two: Reunion

"Who would've thought someone like you two would be related to Straw Hat." Smoker activated his Devil's Fruit power.

"WHITE SPARK!" He yelled.

Both fire and smoke colliding each other like a battle between beasts.

-X-

Luffy and the other stopped their track at a moment as they watch both fire and smoke colliding each other.

"What do you think is happening?" Chopper asked.

"A battle between fire and smoke?" Usopp gasped.

"He said he ate the Mera Mera Fruit." Sanji answered.

"But Luffy, is that true? Are those people really your brother and sister?" Nami asked.

"Yeah!" Luffy smiled. "He's Ace! And she's Yuna!"

Zoro sighed. "Well I'm not surprised you a brother and a sister. But what're they doing on Grand Line?"

"Ace and Yuna are pirates." Luffy said.

"Ace left our island three years before me for searching One Piece. Yuna left our island five years with her Master to train herself stronger."

They all gasped a bit as Nami snapped back to reality. "A-Anyways, let's hurry back to the ship. We should get out of here before the marines come after us."

"Right, Nami-san!"

Luffy's sister. She somehow remind me of someone … Chopper thought.

They all begin to run again as Luffy run backward, watching the battle.

Before Luffy even realizes, he already lost sight of his crewmates.

-X-

"That's strange. Why am I only here?" Luffy asked himself, sitting on the barrel of water at the empty street.

"Where did they go?"

"Jeez, you don't look like you're not even trying to escape." Luffy look up and saw his older brother, Ace and his younger sister, Yuna on top of the building.

"Yo!" Ace greeted

"Ace!"

"Onii-san!" Yuna jumped down, glomped Luffy with a bear hug.

"It so long to see you again, Onii-san!" Yuna smiled, she release Luffy from the bear hug.

Ace jumped down as well. "Long time no see, Luffy."

"Same to you, Ace, Yuna."

Ace laughed. Both brothers started arm wrestling as the three siblings talked about their childhood.

The barrel broken as Ace and Luffy stopped wrestling. "I guess we're both still the same."

"Yeah."

"Sure brings back memories!"

"But … Your nakama are probably looking for you." Yuna said

"Yeah. But Ace, Yuna. What are you two doing in this country?" Luffy asked.

"Huh? What? Didn't you get my message in Drum?" Ace asked back.

"In Drum?"

"Well, nevermind. It wasn't anything important. I have some minor business to take care of in this part of the ocean. I figured I'd try to meet up with you."

"Minor business?"

Yuna eyes soon filled with rage and sadness. It that man, isn't it? Ace …

Luffy looked at Yuna. "What about you, Yuna?"

"Did you forget our promises Luffy?" Yuna sighed.

Luffy blinked at the moment then started grinned. "Of course, how can I forget it."

Liar. Yuna stared at Luffy

"Hey Luffy, wanna join the Whitebeard Pirates? I'm with them now."

"Whitebeard Pirates?"

Ace turn and show his tattoo on his back. "This is the mark of Whitebeard Pirates. My greatest pride."

"So, you wanna join? Your nakama too, of course."

"No." Luffy answered.

Ace laughed while Yuna giggles. "Yeah, though so. Just thought I'd ask."

"Oh that reminded me, Ace-nii. How Whitebeard-jisan doing those days?" Yuna asked.

"Fine, still the same old man you know." Ace smiled. "Whitebeard is the greatest pirate I've ever known. I've decided to make that man the Pirate King. Not you, Luffy."

Luffy continue grinned. "So what? It's just one more person I'll have to fight. I'm going to be the Pirate King."

-X-

"Anyways, let's find your nakama. If the marines catch up with them, it'll get petty troublesome." Ace said.

Ace, Luffy and Yuna walks down the empty street to find Luffy's crewmates.

"Maybe they've gone back to the ship." Luffy stated.

"Which harbor did you anchor in?" Ace asked.

Luffy think at the moment. "Y'know, I have absolutely no idea." He answered.

Yup, still the same old Onii-san. Yuna smiles.

Ace frowned at Luffy. "Hey now. If you're the captain of a pirate ship. Remembering where you docked is a given, normally."

Luffy laughed. "Whatever, don't worry about it."

"Same as always." Ace stated.

"By the way, those nakama of yours. What kind of people are they, Onii-san?" Yuna asked.

Luffy started talks about his crew as they continue walks down the street, then some people came out. "Stop right there, Fire Fist Ace, White Flame Yuna."

More people came out surround them. "As you can see, there is nowhere run. Fire Fist Ace, White Flame Yuna, yours heads is ours. Prepare to die!" Said the leader

"Hey, don't you suppose. Is this other guy … Straw Hat Luffy?" Said one of the man.

"Now that you mention it …"

"The 30,000,000, beli bounty!"

"We're freakin' lucky today! Fire Fist Ace, White Flame Yuna and Straw Hat Luffy! When we have your heads, we'll be promoted three times over."

"Anyway, let's go find your ship. Should we go to the beach?" Ace said as the three D siblings walks pass them.

"Sure!" Luffy replied.

"Hey! You three!" the man yelled.

"Hold it!"

The leader went mad. "Making fools of us ….! KILL THEM!"

"AYE!"

-X-

After Luffy sent the leader flying, the three D siblings started walking again.

"Ah, the ocean!" They walk over the beach as Luffy look out of his ship.

"See your ship, Onii-san?" Yuna asked.

"Ah, it's over there!" Luffy waved. "Oi, I'm over here! Guys!"

"Ah, there he is! I see Luffy." Said Nami, who stand in the crow nest.

"You sure?" Zoro asked.

"Yeah, no doubt about it. With that dumb look on his face .." Sanji stated.

Luffy stretched his hand, catch and hold on the railings, stretched him back to his ship. "I'm … back!" Knocked over Sanji and Chopper.

"Sanji-san! Tony-kun!" Vivi screamed.

Zoro face-palmed himself. "Not again."

Luffy started to laugh. "Sorry about that, Sanji, Chopper."

Sanji grabbed, shook at him like rag doll. "Bastard .. ! Don't you know your own strength!? I oughta throw you overboard!"

"He's right! Do you know how much trouble you've caused us? Act a little more like a captain." Nami said.

"Sorry." Luffy apologize.

"Oh yeah, Ace! Yuna!"

"Aren't they with you?" Zoro commented.

"You sure we should just leave them?" Usopp said.

"Well, they'll be fine. Cause they are strong"

"Are they really strong?" Chopper asked.

Luffy told his crew how strong Ace and Yuna in their childhood days. He smirked, leaning his back on the railing saying that he can beat them with no problem and started laughing.

"And just who can you beat?" Ace jumped onto the railing, making Luffy fall on the ground.

"Oh, Ace! Where's Yuna?"

A figure appeared behind Zoro, which almost scare the crew. "We'll see who beat who after a spar, Onii-san."

Luffy smiles. "Yeah whatever, these are the nakama I telling you guys about."

Ace and Yuna immediately bowed to them, they always know what is right to do. Unlike Luffy, who always would make rude remark about a person. "Hello everyone, I trust my little brother has been in your care."

"Yes, he has." They all slumped.

Ace grinned. "He has no manners, so he'll probably end up burning your hands a few times."

"Yes, he has." All the crewmates commented.

"I'll entrust him to you." Ace added.

Yuna looked at Luffy crewmates then she recognized a friend.

"Chopper?" Yuna whispered.

Chopper turn, looked at Yuna. Instant he recognized, jumped and glomped her. "Yuna~!"

Yuna laughed and hugged Chopper. "Long time no see Chopper, I can't believe you join a pirate crew."

"You guys know each other?" Nami asked.

Yuna nodded. "I meet Chopper two years ago. He save me from freezing to death on the mountain at Drum Island." She laughed.

Nearly everyone sweat-dropped at her comment. What's so funny about freezing to death?

"I glad to see you again, Yuna!" Chopper said as Yuna smiled.

-X-

Luffy, Chopper and Usopp started cheered for Ace and Yuna become their nakama but Ace didn't approve. They ignored him as they kanpai to other things.

"So Yuna, you gonna join our crew?" Nami asked.

She nodded. "I did promise Onii-san I'll join his crew."

"I see, well. It nice to have another girl on the crew." Yuna giggles at Nami comment.

"So, what position are you on the crew?"

"Vice-captain. Luffy say I can be his vice-captain in his crew." Yuna answered to Nami.

"Finally, someone is more mature than anyone on the ship." Nami break into fake tears which make Yuna sweat-dropped.

"Ace, are you really be our nakama?" Luffy asked.

"I'm in pursuit of a man." He drink his water (A/N: I don't know what in his cup, alright) then he continue. "He's known as Blackbeard."

"Blackbeard?"

"The pirate that sacked the Kingdom of Drum?"

"He used to be a member of Whitebeard Pirates, Second Division. My subordinate. Until he committed the greatest crime you can on a pirate ship. He murdered his nakama and fled the ship. As the Commander, I have to find him and finish him off." Ace said.

"So that's why you're after him." Usopp commented.

"The only reason I came to this country is because he was reportedly seen in Yuba." Ace continues drink his water. (A/N: Seriously people, I DON'T KNOW WHAT IN HIS CUP!)

"Then, you're going to the same place we're going." Nami said.

Vivi pull out a map of her country. "Our ship just crossed onto Sandora River. First, we'll land at Erumalu. Then we'll cross inland through Arabasta to here, Yuba. Yuba is where the Rebel Leader is."

"I get it. So you're headed to Yuba, too."

"Wherever, Nami-san, Vivi-chan and Yuna-chan go ~!" Sanji body started waving with heart on his eyes.

"Quit it, Love Cook."

"What did you say, bastard …..!"

"ANYWAY. Looks like you'll be traveling with us for a little while." Nami stated.

"With you along, this'll be a cinch!" Usopp laughed.

Luffy laugh along, then held up his cup. "Let's make it a fun trip, Ace!"

"AYE!" Everyone cheered.

Yup, this is gonna be a fun trip.
