Luffy's an Uncle

Chapter 1

The Niece and Nephew

This is set after Skypiea and before Water 7.


The Strawhats were blessed with an unusually peaceful day. No marines attacking. No sea kings attacking. No nothing was attacking. The wind was calm. Luffy was bored.

"I'm booooored." groaned Luffy. "Nothings happened all day."

"I know isn't it great!." said Nami happily.

"No!" Luffy retorted. "It's boring."

The captain and navigator were the only 2 on the upper deck. Zoro was training on another part of the ship away from curious eyes. Sanji was cooking lunch. Usopp was napping in the boys cabin. Choppe was studying indoors. Robin was reading on the lower deck.

Nami groaned at her captain's lack of appreciation of the peace. "Come on Luffy can't you appreciate the fact that there's no danger for once?"

"No." Luffy replied bluntly.

Nami sighed. "Fine then…." Nami knelt down reach Luffy's, who was lying on his belly and pressing his face against the railing in a fashion similar to a bored child, level. Nami gently, but firmly gripped Luffy's chin with her index finger and thumb and jerked Luffy's head so that their faces were only inches apart. In a flirtatious voice Nami said, "I could do something to excite you, if you want?"

Luffy was caught off guard. "N-Nami what are you-"

Luffy was silenced when Nami placed her finger onto Luffy's lips. "Shush Luffy. Don't say a word."

Luffy wasn't sure what was happening. Nami only acted like this to Sanji and other guys and only to get them to do stuff for her. Luffy didn't know what Nami wanted, but honestly he was enjoying every second of it He felt things he had never experienced before. His heart was beating faster than ever, his stomach felt weird, and it felt awesome.

"Luffy" Nami said in an unusually soft voice. "There's something I want to tell you"

Luffy was silent. This close up he could feel Nami's breath and could see her cheeks redden.

"You looked really cool fighting Eneru," she said.

"Y-you think?" Luffy managed.

"Uh-huh!" she replied cheerfully. "Not to mention really dashing."

"Y-you think?" Luffy managed to repeat. His brain couldn't find anything else to say.

"And really cute!" by that point Nami gently slid her right hand up to Luffy's right cheek and gently placed her left hand on his left cheek. Luffy froze, as so many thoughts flooded into his head. He, for the first time, noticed how pretty Nami looked. "Luffy I think I've…" Nami leaned in closer and closer, then suddenly…

A blinding flash of light appeared, surprising Nami and making her drop Luffy's head, which made a loud thud, as he fell on his face. Nami stood up to get a better look. A dome of golden light around 10 feet in diameter was on the main deck. "What is that?" she said in awe.

Luffy was just too annoyed at the past 5 minutes to give any initial interest to the mysterious light, but after a second he remembered he was him. Still lying on the floor, Luffy lifted his head up a bit to see the light. He looked at it curiously, but then his eyes widened in realisation. "I-it couldn't be."

"Luffy you know what that is?" Nami asked.

Before he could answer Saji barged out of the kitchen, "What's going on!?" Before anyone could answer him Zoro, Usopp, and Chopper came onto the lower deck shouting question about what was happening and what the light is. Robin just kept reading a book as if nothing was happening, causing Usopp to yell.

After another second the light started to fade away and in its place were 3 raven haired figures. A young tall woman in her late 20's with hair as long as Robin's. She was holding the hand of a cute little girl who looked around 6 or 7 years old and a cute, little, skinny, boy who looked no older than 3 or 4.

At the sight of the woman Sanji went into his love mode at the sight of the woman, who wore a jeans vest over a black t-shirt and white shorts. "An angel has come from the light!"

In lightning speed Sanji dashed forward to meet the beautiful woman, with a rose in hand. "Madam, would you do me the honor of having a nice dinner with me under the moonlight this evening-"

Sanji's latest attempt at getting a date was thwarted by Zoro, who had the mystery woman at sword point, making the little girl scowl and the boy scared. "Idiot cook! Don't let your guard down so easily! We don't who she could be."

Sanji's chivalry instincts, plus his strong dislike for Zoro, went into effect at the sight of seeing a woman in danger. "Moss head get your filthy swords away from her!" Sanji swung his leg at Zoro, but he blocked it with his free arm. The 2 were in a stalemate, but the the Strawhats were too used to the swordsman and cooks rivalry to really care.

"Love cook!" Zoro shouted. "One of these days you're gonna…"

"Moss head!" Sanji shouted back. If you hurt…"

"Oh boys…" the mysterious woman finally spoke. Her voice was so soft and silky that it would make most men's hearts melt. It certainly made Sanji give his complete attention to her and even Zoro dropped his guard a little to listen. This proved to be a mistakes as the woman made a lightning grab towards Zoro and Sanji's arms, with a surprisingly strong grip. "You two appear to need to be separated. FLASH!"

With those words the swordsman and cook glew golden in a way similar, but not nearly as bright and radiant, to the light from before. Unlike before the light didn't linger, but this time when it disappeared both men disappeared along with it, shocking the majority of the remaining Strawhats. Fortunately, they reappeared in the same golden light… 5 feet away from the woman, right before Luffy special seat, 10 feet in the air, an arm and a halfs length away from each other. They both fell with a loud thud.

"What just happened…" Zoro moaned.

"Not sure…" replied Sanji, as he moaned. They both had a bump on their heads.

Nami, Usopp, and Chopper's mouths hung open, shocked to see that 2 of their best fighters were just made fools out of. Robin, however, just continued to read as if nothing was happening.

"OH COME ON! AT LEAST REACT A LITTLE!" Usopp shouted at the oldest Strawhat.

The woman glanced upward to where Nami and Luffy were and smiled a very pretty smile. Nami tensed up, but that was no surprise, but what was a surprise was that Luffy seemed completely unphased by this woman. Usually he'd charge in there against anyone who'd dare attack one of his crewmates.

The woman waved at them. "Luffy! Hi there! Get down here already!"

This surprised the other strawhats. "Luffy you know these people?" Nami asked curiously.

"Luffy who is this? a friend?" asked Usopp.

Luffy had an unusual expression of being annoyed at the situation. "Well um…. Wait one second." Luffy jumped from the upper deck to the lower deck, in front of the mystery group of the woman and children, who, without warning, charged at Luffy with a hug that almost knocked him down. Luffy, in return, affectionately hugged them all back.

Now Nami really wanted to know who this woman was. She glared a silent, but deadly glare at them. "Luffy who are these people?"

Released from the hug, the woman smiled. "Luffy you never mentioned me or the kids to your crew. I'm hurt. To repent introduce us now."

"Fine." Luffy sighed. He gestured to the older woman, "Everyone this is my big sister, Aiko."

The Merry went silent, as if the sea itself went silent at the news of Luffy having a sister. Almost all the Strawhats, including Zoro and Sanji, who recovered from falling head first on to the Merry, shouted, "YOU HAVE A SISTER!"

"The captain has an older sister, interesting," Robin said curiously.

"You're reacting now!?" shouted Usopp.

"How can it be possible that this beautiful lady from heaven, shares even a drop of blood with you!" Sanji screamed.

Aiko scowled at Sanji making him flinch. She muttered "FLASH" and appeared next to Sanji in the golden light that she obviously controlled. She smacked Sanji over the head, knocking him back down on the ground, and giving him a second bump. "I don't like what you're implying about my little brother."

"My apologies, beautiful Aiko," Sanji apologized dramatically. He still had the rose in his hand. "Please accept this rose as a token of my affection."Aiko rolled her eyes and ignored Sanji, which caused him to go into depression mode.

Ignoring the skit that was taking place, Luffy continued with introduction, as he gestured to the two unnamed children. "These are Aiko's kids, my niece and nephew. Their names are Ayako, age 7, and Sota, age 3."

"Luffy you're an uncle?" said Nami in genuine surprise. She walked down to the lower deck.

"W-well yeah," Luffy said awkwardly. "B-but more in title than in practice. I certainly won't ever earn uncle of the year."

"Uncle Luffy's just being modest," said the niece, Ayako as she ran up to her uncle, while holding her little brother Sota's hand. She hugged luffy at the waist with one arm and affectionately rubbed her head on him. "Uncle Luffy is awesome!"

Ayako had neck length hair, that was well brushed, and, unlike her mom and Luffy, who had black eyes, she had bluish gray eyes. She wore a soft crimson dress, that went to her knees, and pretty black shoes over white socks. She was very cute. Sota wore a pair of jean overalls over a red shirt. He had well groomed neat hair, as opposed to his uncle who had messy hair, and black eyes. His face was roundish and cute with chubby cheeks.

"Wait a minute!" shouted Sanji, which startled the other. He ran towards Luffy in a second and grabbed his shoulders. "Are you telling me Aiko has a husband!"

"Well actually-"

"I'm a widow," said Aiko bluntly, cutting off Luffy. "My husband died a few of years ago."

This was some depressing news. The Strawhats would've felt sympathy for anyone in her situation, but since she was Luffy's older sister it felt deeper. "I'm sorry to hear that." said Usopp sincerely.

She smiled gently. "Thank you, but there is no reason to feel bad. We've all moved past it, right Ayako dear?"

Ayako nodded confidently with a grin. "Right."

Aiko scanned Usopp's face. "Hey are you Usopp? Yasopp's son?"

Usopp was surprised, "Y-you knew my dad…?"

Aiko nodded, "I'm sure Luffy told you that Yasopp visited our village with Shanks and his crew a long time ago, right?"

"W-well yeah, but I wasn't-"

"You know you look a lot like him, except for the nose and black hair, of course. He always talked about you, which was weird since it seemed to me that he barely knew you."

"Oh umm… sorry he annoyed you," he said, as he rubbed his head laughing.

"No need to be sorry, I liked hearing those stories," she said raising her hand dismissively.

"Besides it's me who you should apologize too. Yasopp bored me to death with those stories and then jammed my head in a beer jug," said Luffy glancing at Usopp, who glanced back at him with an annoyed face.

"Usopp your dad is a member of Shanks's pirate crew?" asked Chopper.

"Oh right you wouldn't know, would you Chopper?" Usopp said.

"A talking reindeer!" both Ayako and Aiko shouted. They both had stars in their eyes in a way similar to Luffy when he saw something unusual. "It's so cute!"

"Stupid humans don't think that makes me happy or anything, you idiots," Chopper said. But by the way he was dancing and blushing, it was obvious he was happy.

"I guess Luffy shares more similarities with his sister than I first assumed," Nami said with a light laugh. But then something dawned on her, in the heat of the moment no one questioned how Aiko and her kids had arrived. She was about to ask, but Zoro beat her to the punch.

"Do you mind telling us how you arrived here," he asked in a tone ruder than how Nami would've done it. He seemed annoyed at whatever she did to him and Sanji before.

"Moss head! Don't talk to such a beautiful woman, so rudely!" Sanji yelled. He then swung a kick at Zoro who blocked it and, once again, the cook and swordsman broke out into a fight.

Aiko didn't seem to care about Zoro's callousness or his and Sanji's random fighting. "I came here using the power of my Flash-Flash fruit."

"Flash-Flash fruit?" Nami said. "What kind of ability does that give you?"

"Based on my research the Flash-Flash fruit gives one the ability to teleport to any location." Robin answered before Aiko had the chance to.

Aiko smiled at Robin. "Impressive. I didn't expect my brother to get such an intelligent crewmate. It eases a bit of my worries, knowing that Luffy has smart lady in his group."

"Thank you for the compliment," Robin said sincerely,

"But sis," Luffy said. "I thought you said that there were limits on how far you could go with that fruit."

"That's true, brother dear. Under normal circumstances there'd be no way I'd be able to travel this deep in to the Grand Line, especially to find a brother whose exact location I do not know." Aiko grinned, as if explaining her power alone was enough to satisfy and excite her. The other Strawhats listened intently at her explanation, except for Luffy and Robin, who already knew that much about the fruit.

Aiko continued, "So to bypass that limit-"

"You have the ability to mark people so they can act as walking ports to use as a way to travel farther distances, correct?" Robin interjected.

Aiko blinked, "Yes that's exactly correct." She turned to her little brother, "You've got a good crewmate on your side, Luffy."

"Thanks Aiko..." Luffy's voice trailed off. His eyes widened with realization. "Wait who did you mark!"

Aiko giggled playfully, "I'd think it would be pretty obvious who on this ship would be marked, little brother."

"You witch!" Luffy shouted. "You marked me! What the hell does that he even mean!?"

"Basically it means that I can appear wherever you are anytime I want, which is a good thing since it means I can visit you whenever I want want, isn't that great!" she said with a big smile, as if not getting the point.

Luffy looked like he'd explode with anger. "No it isn't! Aiko whatever you did to me undo-"

"Are you two fighting?" asked Ayako innocently.

Luffy just blinked several times. Aiko answered her daughter, "I don't know dear." she turned her sly gaze to Luffy. "Are we, Luffy?"

"N-no of course not Ayako." Luffy frustratingly said through his teeth, with a fake smile. "We're just having a spirited discussion."

It was a bizarre sight to the Strawhats to say the least. It was a rare sight, if not one of a kind, to see Luffy attempt to lie and even more rare to see him so… dejected. The lie itself was obviously untrue, but the young and naive Ayako seemed to buy the lie. She smiled a Luffy-like smile. "Oh that's great. I hate to see mommy and Uncle Luffy fight."

"So cute!" Nami squealed. She ran towards the little girl, picked her up, and rubbed her cheeks against her's. Ayako was surprised, but her expression was indifferent as Nami rubbed her face on her's. "You are just the cutest thing in the world!"

It was another strange sight to the Strawhats. Nami didn't usually get this excited unless there was treasure involved. Sanji kind of wished he was in Ayako's place right about now. Today was a whole mess of bizarre and unusual sight and unusual sights, which, in retrospect, is actually fairly normal for this crew.

"Your friend is quite affectionate, isn't she bro," Aiko said as she giggled at the sight.

"She's usually more… different." Luffy tried to explain. Truth was Nami has been acting strangely for awhile now. He was still trying to process what had happened moments before Aiko and her kids had arrived. "Well I've never seen her act like that before."

"Speaking of which you haven't introduced me to your crew yet, have you?" said Aiko.

"Oh I don't think that's necessary. It's not like you really need to know all their names, right?" said Luffy while waving his hand dismissively.

"Yes I do," she replied with a glare, leaving no room for argument. "As your older sister I believe it's my duty to make sure I know who I'm leaving you with."

"Fine," Luffy sighed. There really was no point in arguing with Aiko. Once she wanted something, she got it no matter how much you said no. Luffy gestured to Zoro. "This is-"

"Roronoa Zoro. The former pirate hunter turned pirate, with a 60,000,000 berri bounty and is also known for using the 3-swords style."

Zoro stared at her with a slightly surprised expression. "You've heard of me?"

"Of course. Like I said it's my job to know as much about the people that are taking care my little brother." she said sweetly.

"Honestly he's the one who takes care of us most of the time." Nami said politely.

"Oh really?" Aiko's tone of voice made it obvious that she didn't believe Nami. "So Luffy hasn't run off without a word, gotten you into life or death situations, or done something so stupid that it nearly got him killed?"

"Nope." all 6 other Straw Hats said.

"You're all good people." Aiko said respectfully. "You're more than my little brother deserves."

"What's that supposed to mean?" Luffy felt insulted.

"Oh nothing…" Aiko grinned mischiefly. "Anyway continue, Luffy."

"Fine…" Luffy sighed. He gestured to Nami. "This is Nami, our navigator."

"I hope you're good. My little brother's sense of direction is as bad as a rock's." Luffy didn't even respond.

"I'm probably the best there is!" Nami said confidently earning a few rolled eyes from some of the other Straw Hats.

"Then there's Usopp, who's our sniper." Luffy gestured to Usopp.

"Oh. So like Yasopp, huh?" Aiko noted. "You any good?"

"Oh you bet!" Usopp said proudly. "I could shoot a fly from a 100 miles away!"

"Oh. Okay." Aiko said uninterested.

"She doesn't even care." Usopp said depressingly.

"She probably guessed you're a liar." Sanji said.

"Shut up!" Usopp screamed.

"Your friend is sad, Uncle Luffy." Ayako pointed out.

"Don't worry about him. He's always like that." Luffy dismissed.

"Oh. Okay." Ayako went along.

"Then there's Sanji our cook, Chopper our doctor, and Robin our archeologist." Luffy gestured to the last 3 members of the crew.

"An archeologist?" Aiko repeated in confusion. "Why would you need an archeologist?"

"Well it's not exactly her official position, but-"

"Robin's skills with archeology have actually been pretty useful from time to time, not to mention her huge intelligence44444444444." Nami explained. Chopper and Usopp nodded in agreement.

"Oh she has indeed!" Sanji swooned. "She and Nami are the two most important crewmembers on the whole ship!"

"Why thank you everyone." Robin said sincerely.

"Hmm." Aiko thought for a moment.

"Something the matter, sis?" Luffy asked.

"Oh nothing, Luffy," she confirmed cheerfully. She glanced at Sanji. "You're the cook?"

"Correct my love!" Sanji swooned.

Ignoring Sanji's comment, Aiko placed her hands on Sanji's shoulders, which made his heart race and his mind become dirtier. "You must have the hardest job on this whole ship!" Aiko said dramatically. "Keeping Luffy fed is probably the hardest thing on the planet." Luffy muttered an inaudible curse.

"Oh sweet Aiko! Knowing you have sympathy for me gives me more joy than any other man in the world!" Sanji wailed.

"I see…" Aiko sweat dropped.

"Uncle Luffy, your cook is a weirdo." Ayako whispered to Luffy. Zoro chuckled, hearing Ayako's comment about Sanji's personality and Nami rolled her eyes at Sanji's vulgar display. The guy was flirting in front of a woman's kids for pete's sake.

"He kind of is," Luffy agreed. "But he's a great cook."

Aiko turned her attention to Chopper. "You must be a zoan type, right?"

"That's right. you can tell?" Chopper said as if it weren't obvious.

"It is kind of obvious…" Aiko sweat dropped. "You must have your hands full keeping Luffy alive I imagine."

"Oh no, it's not that bad." Chopper lied.

"Well if he ever crosses the line don't be afraid to scold him." Aiko advised. "That goes for all of you guys too. It is for Luffy's well being after all."

"Sure." most of the crew said, although they do that now.

"Enough!" Luffy practically screamed. "Is there a reason you're even here?"

"Oh yeah. I need a favor of you, little bro." Aiko said.

"What is it?" Luffy asked nervously.

"I need you to babysit Ayako and Sota for a few days, while I go complete an important job." Aiko explained.

It took a second for Luffy and the rest of the Straw Hats to process what Aiko had just asked.

"What?!" Luffy screamed unrestrictedly.

"You heard me, so could you do that for me? Please?"

"B-but what about Makino or the Mayor?"

"Both of them are busy."

"But what about… Grandpa or Dadan?" Luffy offered weakly.

"You'd really want me to leave our precious Ayako and Sota with Grandpa or the bandits?" Aiko argued.

"W-well no… but…" things were getting out of hand.

"Bandits? some of the Straw Hats repeated. 'What the heck are they talking about?'

"Nami!" Luffy suddenly screamed. "Talk some sense into her! Tell her why I can't babysit!"

"Well... um... we are close to the next island so if we stay there til Aiko comes back it should be fine." Nami explained.

"Not helping," Luffy said dejectedly.

"U-Uncle L-Luffy? You don't want us around?" Ayako whimpered with tears in her eyes, while Sota silently sniffled..

"N-no I just meant-"

"I hate you, Uncle!" Luffy felt like he was just impaled.

"Luffy how dare you make a little girl cry!" Sanji screamed. "Especially your own niece!"

"Now, now Ayako. True Luffy is being quite cruel to you and Sota," Aiko soothed while hugging Ayako from behind. "But we'll just have to accept that our precious Luffy has become the kind of man that ignores his family."

"But I'm not-"

"Oh Luffy it would be alright if we let them stay for little bit, wouldn't it?"Usopp asked with a tear in his eye.

"Yeah and I think it would be kind of fun, actually," Chopper whimpered.

"You are being kind of heartless here, Luffy," Nami scolded.

"They're actually buying it?" Zoro muttered under his breath.

"Oh don't worry about us everyone," Aiko assured. "I'll just let Grandpa watch over the kids while I'm gone."

"Wait no! I'll watch them!" Luffy blurted out without thinking.

"You will? great!" Aiko said with a big smile.

"Yeah! We get to stay with Uncle Luffy!" Ayako cheered. "Isn't that great, Sota?"

Sota nodded with a smile. "Yeah."

"This is okay, right?" Aiko confirmed.

"Well…"

"Call!" a brown bag and a pink bag appeared in Aiko's hand via her flash power. "Call!" a few sheets of paper also appeared in Aiko's hand. "I knew using tears would work."

"Wait a minute, that was fake?!" Luffy realized

"Of course not," Aiko said unconvincingly. "Me and my kids were definitely upset with you for not letting them stay here, right, Ayako? Sota?"

"Right." Ayako said. "Sorry for saying I hated you Uncle Luffy."

"Sorry." Sota whispered.

"I was tricked," Luffy slumped in a depressing state.

"Don't be sad, bro," Aiko comforted. "Besides you'll be too busy to be depressed." Aiko handed Luffy the two bags and sheets of papers. " The bags have their clothes and the papers contain things what to eat, when to sleep, and other stuff."

"Yeah. Okay…" Luffy said dejectedly.

"Well it looks like we'll be playing babysitter for a little while," Nami said good naturedly. She walked toward Ayako and Sota. "We'll take good care of you two, while you're here."

"Thanks Miss Nami," Ayako said appreciatively.

"No need to be so formal, Ayako. You and your brother can call me Aunt Nami from now on." Nami offered.

'Aunt Nami…?' the male Straw Hats thought in confusion.

"Oh. Okay, Aunt Nami," Ayako agreed. "Hey wait a minute. Are you Uncle Luffy's girlfriend?"

"What?! Girlfriend?!" Luffy and some of the other crew members screamed hysterically, while Robin chuckled under her breath and Zoro just plain didn't care. With one word Luffy went from feeling defeated to feeling red in the face.

"That's a good question, Ayako," Aiko agreed. She turned her gaze to Nami, "So are you?"

Nami smile. "Oh no. Luffy's lucky, but he's not that lucky."

"That's for sure," Sanji snorted. "Like my darling Nami would ever lower herself to go out with our idiot captain."

Almost immediately, Aiko "flashed" near Sanji and smacked him over the head. "I thought I made it clear on how I feel about people insulting my brother."

"My apologies, Aiko," Sanji said poetically. "I will make up for it by putting my heart and soul into watching your precious son and daughter!"

"I'd rather you not."Aiko gave a disapproving stare to Sanji. "FLASH!"

Aiko appeared next to Luffy and her kids. "Well I'll be leaving now." Aiko crouched down to her kids. "You two be good now, okay?"

"Okay mommy," Ayako said adorably.

"Okay," Sota said cutely.

She kissed both of their heads. She rose to face Luffy. Side by side you could tell Aiko was a head taller than Luffy. "Take care of them for me, bro."

"I will," Luffy sighed.

"You better, 'cause I'll murder you if you don't," Aiko said a sweet, but creepy voice, which made Luffy flinch.

"O-okay, sis…"

Aiko turned to face the rest of the Straw Hats. "I'll be off now. Please take good care of my kids and if they misbehave don't hesitate to scold them."

"Don't worry they're in good hands," Robin assured.

"We'll take good care of them," Nami said confidently.

"I'll treat them like my own kids," Sanji said passionately.

"They'll have with the great captain Usopp!" Usopp proclaimed proudly.

"If they get hurt I'll patch them right up," Chopper assured.

"Thanks you guys," Aiko said kindly. "It really eases my nerves to know my little brother has such a kind group of friends with him."

"Hey Luffy I'm gonna go to Foosha Village, so do you wanna give a message to people back home?"

"Yeah. I would actually," Luffy answered. "Tell them I'm on my way to becoming the king of the pirates."

"Yeah. I will." Aiko nodded with a grin. "Bye everyone. I'll see you soon. FLASH!" and with that she was gone.

"Well you guys," Luffy said to his crew after a moment of silence. "Looks like we're babysitters. Prepare for the hardest challenge of you life!"


That puts an end to that chapter. I did not think it would be that long. FYI this story isn't connected to Luffy's Terrifying Mom. I hope you liked Aiko and her kids. I assume you all noticed the LuNa in the story. I'll post the next chapter as soon as possible. Tell me what you thought of Aiko, Ayako, and Sota. Please review.
