Blizzard, Aika, Kumi, Jupiter, and Vice-Admiral Auguste © Me

Summary- After their little adventure on Punk Hazard, the Straw Hats, along with their new ally, Trafalgar Law, head to their next destination: Dressrosa. However, Aika and Kumi, the girl and puppy that the crew had taken in on Luffy's orders, have come along for the ride. As they make a few stops here and there, Aika forges bonds with each of the Straw Hats, but a shocking revelation will change hers and Luffy's life…will it be for better or worse?

Ch. 1- The Power of Music

When we last left the Straw Hat Pirates, they had recently formed an alliance with one of the Seven Warlords and the Captain of the Heart Pirates: "Surgeon of Death" Trafalgar Law and his dog, Jupiter, whilst at the half-burning, half-freezing island of Punk Hazard. Law planned to take down one of the Four Emperors, Kaido, and as the first phase of the plan, he and Luffy kidnapped the mad scientist, Caesar Clown, which is successful. They also successfully a group of captured children that Caesar had abducted for his experiments and are later taken back home by Marine Captain Tashigi of Marine Base G-5. However, Aika, a little girl who ate an Artificial Devil Fruit called SMILE whom Luffy had grown quite fond of, and her puppy, Kumi, become the Straw Hats newest recruits.

Law has made a deal with Donquixote Doflamingo, who demands that he have Caesar: either Doflamingo quits the Seven Warlords…or he will never get Caesar back, meaning that Doflamingo will have to be forced to deal with an angry Kaido if he didn't comply with Law's demands.

Doflamingo was than pleased by this, and rushed to Punk Hazard after Law called him. Unable to find Law and the Straw Hats, he intended to kill Vice-Admiral Smoker and his men instead in order to silence them about his underground connections. Luckily though, an old friend came to Smoker's rescue: Ex-Marine Admiral Aokiji, better known by his real name, Kuzan.

Meanwhile, after the Straw Hats take a rest from Punk Hazard…Law unveils a shocking revelation: Aika is actually Luffy's younger sister, which shocks the Straw Hat crew. The only ones who do not know are Luffy and Aika, who are fast asleep in bed.

"Aika is Luffy's sister?!" Nami asked. "A-are you sure?!"

"I checked at least 3 times," Law said. "The blood tests came out positive. They even have the same blood-type: F."

"How shocking…!" Kin'emon whispered.

"…Come to think of it…she does laugh like him," Nami muttered.

"And if you think about it, Luffy looks like a little bit like her if he were a girl," Zoro added.

"But how can she be his sister?" Sanji asked. "I mean…didn't Luffy's mother die, 13 years ago?"

"…It's possible that his father may've had a second spouse after her death," Robin said. "Meaning that if what Law says is true, Aika is actually Luffy's half-sister."

"That seems to be the consensus," Law said. "I know this comes off as a big shock to you people, but I just thought I'd tell you so I wouldn't be distracted from the plan."

A pause…but then, Usopp started laughing.

"I don't believe it!" he said. "Luffy's got a little sister, of all things! Don't that beat all? Wait until he hears this! He's gonna flip! C'mon, Chopper! Let's go wake him up and tell him the good news!"

"Yeah!" Chopper agreed. "Aika should hear about it, too!"

With that, the two ran off, preparing to head to Luffy and Nami's room, when suddenly…

"HOLD IT!" Nami shouted, causing Usopp to skid to a stop, thus causing Chopper to accidentally bump into him.

"What's wrong, Nami?" Usopp asked.

"Yeah, what's the matter?" Chopper asked.

"…We can't tell Luffy," Nami said, "or Aika!"

"EEEEEEEEEEEEHHH?!" Usopp and Chopper cried.

"What do you mean, 'We can't tell Luffy'?!" Franky asked.

"That's just what I mean!" Nami said. "We can't!"

"But Nami, why not?!" Usopp asked.

"Nami, with all due respect," Sanji said, "don't you think that these two deserve to know they're related?"

"First of all…Aika just joined us," Nami said. "If we tell her that Luffy's her brother, it might shock her too much! What if she thinks we're lying to her and decides to hate us?!"

"Well, what about Luffy?" Franky asked. "Can't we tell him, at least?! Especially after what happened to-"

"THAT'S EXACTLY WHY WE CAN'T TELL LUFFY!" Nami shouted in a voice so loud, it could wake the dead.

"Scary…!" Usopp and Chopper whimpered, hiding behind Brook and Blizzard.

"Okay, Nami," Zoro said. "You are making no sense, whatsoever."

"I must say, I'm quite confused, as well," Brook added, crossing his arms and tilting his head. "You're saying we shouldn't tell Mister Luffy that Young Miss Aika is his sister…because of Mister Ace's death, two years ago?"

"Exactly," Nami said. "Guys…think about it. I know Luffy may look and act like his usual goofball self…but I'm pretty sure Ace's death changed him…and not in a good way. What if he's afraid to love someone like that, again, and shut his heart away? That's why we can't tell him!"

"Nami…you know this won't work," Robin said. "Luffy's going to find out eventually."

"We understand you're just trying to protect Luffy," Zoro said, "but…you can't treating him like he's a little kid, forever."

'He's right, you know,' Blizzard thought, nodding his head.

"Robin, I'm not stupid," Nami said. "I know Luffy will find out…but if I'm afraid of what will happen if we tell him and something did happen to Aika. His heart can't take that kind of pain, again! First his mother…then Ace…it's too much on him!"

"So…what do we do?" Usopp asked.

"…I don't know…yet," Nami replied. "Maybe…maybe we will tell Luffy…but only if it seems like he can take it."

With that, Nami stood up.

"Thank you, Traffy," Nami said. "I'm…going back to bed now. Goodnight."

Law nodded his head before Nami headed back to hers and Luffy's room and climbed back into bed. As soon as she did though, Luffy awoke with a yawn.

"Hey," he said, sleepily. "Where'd you go?"

"Nowhere," Nami answered, smiling. "Just to the bathroom, that's all."

"Oh…okay," Luffy yawned before he lied back down. As he did, he looked at Aika, who is still sleeping soundly in the form of a Honshu Wolf pup, and smiled warmly as he gently stroked her fur before he fell right back to sleep.

Nami smiled at them…but then, her smile faded and is replaced with an expression of concern and uncertainty as she looked up at the ceiling.

Now…she was actually wishing that Law did not tell her and the others about Aika's relation. All she did was sigh…and cover her eyes with her hands…but she felt as if she would not be able to sleep well for the rest of the night.

'Dammit,' she cursed, mentally.

The next morning, everyone is up and about, but it looked like they did not have much sleep last night. The morning newspaper had already come, and Law seemed to be a bit disappointed about the front page article.

"So…he hasn't complied yet, eh?" Law asked…but then he smirked. "No matter. It's only the first day."

"Ugh…I barely slept, last night!" complained Usopp, who is wearing a yellow open shirt, a hat that looked like a horned beetle with the word "KABUTO" on it, a white-and-pine-green wristband around his right wrist, and a pair of black pants. "I was so shocked about what Law said about Aika, I couldn't sleep a wink!"

"Yeah, me too," Chopper agreed, wearing his signature hat and blue hat, but also a green shirt with a pink cherry blossom design, and a pair of mahogany pants. "I actually forgot all about Doflamingo coming to attack us!"

"DAAAH! THAT'S RIGHT!" Usopp screamed. "Why hasn't Doflamingo tried to attack us, yet?!"

"Oh, will you guys relax?!" questioned Zoro, who is wearing a green jacket with the sleeves ripped off at the shoulders, leaving gray fur trim, his black pants, and his haramaki sash. "If he was gonna attack us, he would've done it, by now, you idiots!"

"Now, Zoro," said Robin, who is wearing a purple top with the kanji for "flower" on the left side and a lavender open skirt that reached down to her ankles. "Don't be so harsh. We all had a bit of a rough night."

"She's SUPER right about that, bro!" agreed Franky, who is wearing a light blue shirt, a red Speedo, and had his hair styled in dreadlocks. "The news about Aika was a real shock, you know! Plus, I was up all night, trying to keep a look out for Doflamingo, myself!"

"By the way," Zoro began, "where's Luffy?"

"In the kitchen, eating breakfast," answered Nami, who is wearing a pair of low-rise jeans and an orange bikini top with light yellow trim.

"Still?" Usopp asked. "Ah…no surprise."

Kin'emon and Momonosuke are currently sitting on the deck, eyes closed in meditation, while Caesar, who really had nothing better to do since he was chained up, decided to just sit by and count the clouds as they rolled by.

"76…77…78…" he counted.

XXX

"Whew~! I'm stuffed!"

Luffy, who is wearing a red jacket with the sleeves rolled up and white trim around the sleeves and zipper, patted his bulging gut and let out a satisfied belch as he had finished his breakfast. Sanji, who is wearing a blue casual shirt and black pants, just sighed in annoyance.

Blizzard, who is wearing a white-and-gray scarf, is lying by the table, feeling rather tired, as well.

"Glad you're satisfied," Sanji muttered before he picked up another plate, which had some croissants drizzled in a strawberry syrup with a side of scrambled eggs and a glass of tangerine juice. "Here."

"Huh?" Luffy asked. "What's this? A snack?"

"It's not for you, dumb-ass!" Sanji said. "It's for Aika! She's still asleep, right? This is her breakfast. Go wake her and give it to her, and don't you eat a crumb!"

"Oh!" Luffy said as he slimmed down to his regular figure and took the plate. "Got it!"

With that, he went to his and Nami's room, where Aika, how is now in her human form, and Kumi are still asleep.

"Oh, Aika~!" Luffy called as he entered. "Wake-y, wake-y, eggs and bake-y~! Shishishishi! I'm just kidding! It's not eggs and bacon. It's eggs and some weird crescent things."

Aika yawned as she sat up in bed, as did Kumi.

"Good morning," Aika said, sleepily.

"Here you go!" Luffy said, giving Aika her breakfast. "Courtesy of Sanji!"

Aika smiled before she began to eat. She gave Kumi one of her croissants, as well. Luffy watched her before he took a croissant for himself.

"…Hey, Luffy," Aika said.

"Hmm?" Luffy hummed.

"…Is it okay?"

"Huh?"

"Is it okay for me to be here? I mean…I don't wanna feel like I'm holding you guys back or anything."

"Holding us back?" Luffy asked. "What makes you say that?"

"Well…Mister Traffy was talking about all this plan stuff, and…well…" Aika muttered.

"Oh, the whole alliance thing!" Luffy said as he took a bite out of a croissant. "Yeah, that's nothing you need to worry about. That's really grownup stuff and whatnot."

"Oh," Aika said.

"Yeah," Luffy said as he swallowed.

A pause…but then, Aika looked up upon hearing the soothing tunes of a violin.

"What's that?" Aika asked.

"Huh?" Luffy muttered. "Oh! That's probably Brook!"

"Brook?" Aika repeated.

"The skeleton guy," Luffy replied. "He's practicing his violin like he always does after breakfast."

"He does?" Aika asked.

"Yep," Luffy said. "He is our crew's musician, after all."

A pause…but then, Aika got out of bed and went upstairs.

"Aika?" Luffy asked before he and Kumi followed her.

The 6-year-old raven-haired girl exited from Zoro and Robin's room, which was formerly known as the Women's Quarters, before she walked across the grassy deck, climbed the stairs to the aft of the ship…and found Brook, who is wearing a black-and-white vertically-striped suit and a large beige sunhat, bowing the strings of his violin to the tune of "Binks' Brew".

"…Wow…!" Aika whispered, her eyes wide with wonder and awe.

"I know," Luffy said, smiling. "He's good."

Just then, Brook stopped playing and turned to see Luffy, Aika, and Kumi.

"Oh! Mister Luffy!" the skeleton said. "And Young Miss Aika and Kumi! Good morning!"

"Good morning," Aika said. "That's a nice song you were playing."

"Yohohohohoho!" Brook chortled before he took a gracious bow. "Why thank you, my dear! This song was sung by pirates of old, you see! An old favorite of mine!"

"Shishishishi!" Luffy laughed. "Yeah! We sing it when we're in a really good mood, like at a party or something!"

"Really?" Aika asked.

"I can tell by the look in your eyes," Brook began, "that you seem to have good taste in music, too, Young Miss Aika."

"Y-yeah, actually," Aika answered. "My Mommy used to be singer."

"Whoa! A singer?" Luffy asked.

"Yeah…she was really where I grew up," Aika answered. "She made lots of money and sang at bars and stuff."

Then, Aika's smile faded.

"Sorry," she said. "It's just…"

"It's okay," Luffy said. "You don't have to talk about it if you feel like you're not ready."

"Yeah, Aika…don't push yourself," Kumi answered.

"Thanks," Aika said.

"Yohohoho!" Brook chortled before he held his violin out to Aika. "Would you like to draw it?"

"Me?" Aika asked. "Can I, really?"

"Of course!" Brook answered.

Hesitantly, Aika took the string instruments into her hands, placed her head on the chin rest, and then placed the bow on the strings. At first, the notes came out a bit sour…but then, as Aika closed her eyes and began to slide the bow back and forth…a beautiful melody soon flowed throughout the atmosphere of the ship. Everyone stopped whatever business they were doing to listen to the sweet, soothing sound.

"Oh, my god…!" Usopp whispered.

"That's beautiful…!" Nami added.

"Such a pleasant melody!" Kin'emon chimed in.

"How magnificent!" agreed Momonosuke.

Law and Jupiter seemed rather interested by the music, as well.

"You gotta admit, that actually does sound pretty nice," Jupiter said.

"Yeah…I guess so," Law agreed.

"Hmph…!" Caesar scoffed. "My dead grandmother plays better than this."

BAM! Sanji kicked the captured scientist in the face, again.

"Shut up!" the cook shouted. "You're ruining everyone's good mood, you jackass!"

"Shu-ho…!" Caesar coughed.

Soon, Aika stopped playing and looked at Brook, who laughed and clapped his bony hands, and Luffy was doing the same.

"Wow, Aika!" Luffy said. "You can play!"

"Absolutely splendid, my dear!" Brook exclaimed.

"Thanks," Aika said. "My mommy taught me how to play when I was 4."

"A musical prodigy," Brook mused. "Imagine that! Yohohoho!"

"And I can sing, too," Aika added.

"You can sing?!" Luffy asked. "Ooh! Sing a song for us, now!"

Aika blushed a little bit.

"Well…I don't know," she said, sheepishly.

"We understand, Young Miss Aika," Brook said. "Every musician gets rather nervous! Even one such as myself!"

"You get nervous?" Luffy asked, surprised.

"Indeed," Brook answered. "Why, I can't recall how many times I got the jitters before going out on stage during my world tour!"

"My Mommy used to get nervous, too," Aika said. "She told me whenever she got nervous…she imagined her best friend out in the audience."

"Yohohoho!" Brook chortled. "And that's just what I did, my dear."

"…Hey, Mister Brook?" Aika asked.

"Yes?" Brook asked.

"…Is there a piano around here?" Aika asked.

"Why, yes!" Brook answered. "Why?"

"Well…I think I wanna sing now," Aika said, "but…will you play the song with me?"

"Young Miss Aika…I would be delighted to," Brook said.

Aika smiled, as did Luffy and Kumi.

"Hey! Franky!" Luffy called. "Can you bring Brook's piano out?!"

"Sure!" Franky answered.

Later on, Brook is sitting in front of his piano with Aika sitting next to him. The rest of the Straw Hat crew, Law, Jupiter, Kin'emon, and Momonosuke sat around them.

"If you feel too nervous, we can always try again, later," Brook said.

"It's okay," Aika said before she looked at the audience before her. Among them was Kumi, who smiled at her and wagged her tail, causing the wolf-girl to smile back.

"This is a song…my Mommy used to sing to me," Aika said before she cleared her throat and began to sing.

(A/N: the song is "Mother's Song" from Wolf Children.)

"I had to see you and so I could to meet you,

I always prayed while rubbing my stomach~

Ooh~! Ooh~!

What kind of face will you have~?

Ooh~! Ooh~!

What kind of voice will you have~?"

Soon, Brook started to play the piano in time with her voice.

"My reflection is in your big pupils,

And a tear drop splits on your cheek~

Rice~! Rice~!

Come, the rice is ready~!

Ta-ta-ta~! Ta-ta-ta~!

Come, let's go for a walk~!"

As Aika sang and Brook played, Franky was already in tears, and Nami looked like she wasn't too far off, too.

"I hold you in my lap while you cry your eyes out,

As you tell me what's wrong~!

It's all right, I'm not going anywhere,

No matter what happens, I'll always be with you~!

I like your smiling face,

It gives me strength whenever I'm feeling down~!

Lu-lu-lu~! Lu-lu-lu~!

Come, let's sing a song~!

Come, let us howl together~!"

Luffy sniffled as he screwed his eyes shut to keep his tears from falling while Nami, who is already in tears, held his shoulder and smiled. Robin sniffled as well as Zoro held her, her tears streaking down her face.

"Ki-la-la~! Ki-la-la~!

Grow up to be carefree~!

Aika runs and counts the clouds,

I play with Aika and the wind starts blowing~

The flowers are covered, and the red pipes chime,

On four legs, on two legs~

A new morning, a new wind~

The preparations are done for you~

A new morning, a new light~

The whole world is for you~

A new morning, a new rainbow~!

The world is full of wonders~!"

Sanji smiled and sniffled as he wiped a tear away from his eye.

"Saw that, cook," Zoro said.

"No, you see, I accidentally got some pepper in my eye in the kitchen and…" Sanji began…but then he sighed. "Ah, screw it. I'm not made of stone."

Momonosuke sounded like he was trying to choke back sobs, but then, Kin'emon smiled and put a hand on his son's shoulder before smiling down at him, which caused the young boy of Wano to smile back and hug his father.

"Which of the two roads will you choose~?

You gaze intently into the far off distance~"

Brook's playing soon slowed down into a sad, slow melody, and soon Aika's voice did the same.

"I can do it for you,

Is there already nothing left~?

Someday

When you start your journey,

I'll be sure to smile

And see you off~!

Ooh~! Ooh~!

But I will be a little lonely~

Whoa~! Whoa~!

Please…live a good life~"

Then…the song was over. Brook and Aika looked to their audience…and saw that most of the members, except Law and Zoro, are in tears.

"Everyone?" Brook asked.

"W-what's wrong?" Aika asked. "You…you didn't like it?"

"No, Aika," Usopp answered, wiping his eyes. "We…we LOVED it!"

"BWAAAAAH~! THAT WAS BEAUTIFUL~!" Franky sobbed. "I'm not crying, you jerks!"

"You sang that song so wonderfully," Robin praised. "I…I almost felt like it my own Mother was singing it to me!"

"That's what I felt, too…!" Luffy sniffled.

"Ah, god…the tears just won't stop!" Blizzard cried as he wiped his eyes.

Aika smiled…but then she sniffled and found herself in tears, as well.

"Aika?" Nami asked. "Are you okay?!"

"I'm sorry," Aika said. "It's just…nowadays, I can't help but cry whenever I sing that song."

"Yohohoho!" Brook chortled as he gently petted Aika on the head. "It's all right, my dear. Whenever we hear a song we cherish, one can't help but be in tears. That's the power of music, Young Miss Aika."

Aika smiled at this.

"Thanks, Brook," she said before she turned to the others. "And thank you all for listening."

"You're welcome," Robin said.

"Maybe you can sing for us again, sometime!" Momonosuke suggested.

"Shishishi!" Aika laughed. "Yeah…maybe I will."

Kumi then went up and licked Aika's face, causing her to laugh.

"Kumi, that tickles!" she exclaimed.

Everyone smiled and laughed a little at the two friends…but then, Luffy spotted something out in the distance in the corner of his eye.

"What the…?" he whispered before he took a closer look. Once he did…he gasped.

"Luffy?" Nami asked. "What's the matter?"

"…Aika, go hide," Luffy said.

"What?" Aika asked, confused. "W-why?"

"Go hide, now!" Luffy shouted, and Aika gasped before she and Kumi ran off.

"Aika! Kumi! Follow me!" Blizzard called, and the two youngsters followed him into the Aquarium Bar. Once there, Blizzard opened the pantry, where Aika, who transformed into her wolf form by now, and Kumi quickly went inside.

"Stay in here and don't come out," Blizzard said.

"Okay," Aika said before Blizzard closed the door.

Back outside, Law is seen dragging Caesar down below deck.

"What do you think you're doing?!" Caesar questioned. "Put me down!"

"Ah, shut up!" Law barked before he stuffed Caesar in a trunk. "If the Marines see you, now, the plan is in ruins!"

"Why you no-good-" Caesar began, but Law slammed the trunk shut before he could begin ranting and went back upstairs.

Kin'emon and Momonosuke hid in the Men's Quarters.

The reason they scurried to find a hiding place…was because a Marine battleship was headed their way.

"Great," Usopp muttered. "Of course the Marines would show up. Why am I not surprised?!"

"Just act natural," Nami said. "Maybe they'll leave us alone."

"I wouldn't bet on it," Zoro warned.

Soon, the battleship came to a stop beside the Sunny, and not long after…a tall, muscular man, at least about 6'10" tall appeared. He wore a mahogany suit with a dark green ascot, and wore a Marine coat with the kanji for "justice" on the back. He has long, bronze-yellow hair that is pulled back in a ponytail, as well as a mustache and beard of the same color. His turquoise eyes looked down at the Straw Hat crew, and a smile played upon his lips.

"Ah, if it isn't the infamous Straw Hat Pirates?" the man inquired. "A pleasure to meet you all, at last."

"Who the hell are you?" Luffy asked.

"Ah, yes, of course," the man answered. "Permit me to introduce myself: I am Vice-Admiral Auguste of the Marines. Please, rest assured…I'm not here to arrest any of you. My men and I are just here to do a thorough search of your ship, if you don't mind."
