Several days later since the raid

On another unnamed island

"I helped you with building your island, so now is your turn to repay the favor, Vert!" Neptune pointed her finger at Vert.

"Did I say otherwise?" Vert sniffed and winked. "The last raid provided us extra materials for building another town. And we learned enough about building a town, so this should be even faster."

"True… and we should go outside and attract more people to live here…" Blanc hummed as she looked at Pudding Island blueprint.

It's been three days since construction of Pudding Island started. Even with their experience and skill, they felt they might need more help. That's why Big Mom spent money on hiring construction experts this time.

"Oh boy~ I am so glad mama didn't hesitate on spending budget on me."

"It's for betterment of our family. More islands equal more people and more power," Blanc nodded.

"With top experts, all of us will get our islands in no time."

"Is there anything you want to add to the main building, Ms. Neptune?" One of the hired experts asked.

"Hmm… maybe, two more pudding section here and a big spoon on here."

"Understood. We will work on them right away."

"Hum hum~ pudding pudding~ here~ there~ yummy~"

"I can already see your eyes turning into puddings," Blanc stared at Neptune and giggled bit.

"I will be~ the best pudding master~ in the world~!"

"Guys! We got bounties on our head!" Noire shouted as she rushed toward them with papers on her hand.

"Really? That fast?" Vert opened her eyes wide. "I guess we made quite huge impression."

"I can't wait to see my number!"

They all gathered and looked at their bounties.

Bounty: 37,500,000 Berry

"Hmm… not bad for start," Vert smiled with arms crossed.

"It's weird that we all have different bounties although we all made our debut at the same time," Blanc said, holding her bounty poster. "It's interesting that they chose to use our normal form and transformation form for bounty pictures.

All four posters had split image. Each contained two different faces.

"Waaaah!? No fair! How come I am the only one who didn't pass 30 million mark?" Neptune yelled and crumpled her bounty poster. "There got to be error! Those idiot marines! Grrr..!"

"Now that I think about it… how did World Government figure out our name and code name?" Vert pointed at her printed name.

"Morgans. Remember him? He was at the tea party, taking pictures. He probably memorized everything about us."

"Well. We asked for him to spread our news, so this is convenient," Noire smiled and pondered with her eyes closed.

"What's this? Hey look guys! Our ladies got bounties on their heads!" one of henchmen shouted.

"Oh really? Let me take a look!"

One by one, they started gathering around Four Heart Sisters.

"Oh wow! Lady Vert has the highest bounty!"

"You look so beautiful in the poster, Lady Noire!"

"Lady Blanc. I think more people will come to propose to you than hunt you. heh heh~"

"It looks promising start, m'lady~"

"Keep up the pace! Maybe, mama will grant you position of Sweet Commander!"

"Oh ho ho ho~ you guys are flattering. We are far from being that good," Neptune wriggled in excitement. "At least, all of us will have minister positions and islands to rule."

"Well… brother Peros basically did the whole thing… he saved us back there. I am not sure whether we deserve this bounty…" Noire bent her face and sighed deeply.

"What are you talking about, Lady Noire? You and others basically mopped the floor with those marines during that raid! The fact that you ladies held your own against Captain Tailor should speak volume for your capacity!"

"Yeah, World Government is definitely seeing your potential!"

Praise after praise made them flustered. They looked at each other.

"We are still far off. We should keep practicing with our brothers."

"Anyway, status on our ship?"

"It should be completed by today, m'lady."

"Today… today is February 10… wait… isn't mama's birthday February 15?"

"Correct."

"Damn it… we focused so much on our projects that we forgot to prepare for mama's birthday! I don't want to think how she will act when we don't bring any gift…" Noire gulped and started shaking in fear.

"You are thinking too much, Noire. When was the last time mama got angry for lack of gift from us?" Neptune tabbed her back.

"While it's true that mama is lenient because of belief of pirate life, we should still prepare mama's birthday gift," Vert snapped finger. "It will give her our lasting impression."

"True. Especially if the gift is something hard to get," Blanc nodded in agreement.

"I think we should save gift from our land for later. It would be most memorable if all of us produce our specialties from our islands and presents them to mama at the same time."

"That's why we are going for booty, right?" Neptune glanced at Vert.

"Yes… we should be getting intel soon."

"Lady Vert. We have intel on some convoy."

"Another marine ships like last time?"

"No. This time, it is a merchant ship."

"What's on the ship? And escort?"

"Gold and other treasure extracted from Eldorado. I believe few merchants are on the ship."

"Good. That's our target," Vert nodded.

"So… are we going now?"

"I think it's better to wait for our ship."

"Agreed. I want to test our new ship. Hey. You said our ship will be completed by today. Do you think we can make it in time to intercept that convoy with our ship?" Blanc handed bounty posters to one of henchmen and asked.

"I think so. You should be able to reach the ship in time."

"Good. Update us as soon as our ship is finished."

"Yes, ma'am!"

"In the meantime, let's focus on construction overseeing."

"Okay. I will take that section," Noire stretched her arms.

"Good luck. Let's meet up at harbor once we receive news," Vert waved hand and moved to her designated area.

Few hours later

"Wow! It looks super nice~!" Neptune almost dropped her jaw.

"It's definitely fitting to us. Of course, it's thanks to my design sense," Noire boasted her designing skill as usual.

The ship's flag had not just Big Mom's Jolly Roger, but also four hearts overwrapping side by side. The ship's head was consisted of four female statues holding a heart symbol together. It showed symbol of their unity. It was similar size to most of their siblings' ships. It was about half size of Queen Mama Chanter. It could house hundreds of crews. It contained 8 cannons on each side and one special cannon at front.

"Fantastic! I can't wait to hop on this thing!" Vert clapped her hand.

"So this is our ship… what should we name it?" Blanc asked after pondering bit.

"Good question, Blanc. Hmm…" Noire also started pondering.

"Oh, I know! Hyper Almighty Heart Combo!"

"That's definitely pass..."

"Boo~ you don't have to be so mean!" Neptune whined and pouted.

"But I think Neptune does have point. We should definitely include word 'Heart,'" Vert added.

"I think we should keep the name simple…" Blanc closed eyes and went into deep thought. Then, she opened her eyes and suggested. "Four Eternal Hearts."

"I like that. At least, it's better than weirdo Neptune came up with."

"Hey!"

"That's settled. Let's ride our new ship, Four Eternal Hearts! Guys! Get onboard. Gold and treasure are waiting for us!"

"Aye, ma'am!"

As Four Heart Sisters stepped on the ship, other pirate members and homies followed behind. After they set mast, the ship began to sail to their destination.

Certain sea within New World

"Any sign of the ship?" Noire asked while watching horizon through a binocular.

"No, ma'am."

"Are we on the right place?"

"We should be."

"Then, I guess we arrived much earlier."

"Which is good. It gives us more time to think and prepare," Vert said as she polished her spear.

"So is this ship related to World Government?" Blanc asked while sitting on a chair and reading a book.

"Nope. It looks like a private ship."

"It doesn't matter who are on the ship. We will bust them and get our prize!" Neptune thrusted her fist and sniffed.

"That's the scary part. We don't know what kind of mercenaries they have onboard. So we better be careful."

"Found it! It's coming this way!"

"About time!"

A ship about same size as Four Eternal Hearts showed from horizon.

"Do you see anyone on the ship, Noire?"

"Few… hmm… I can't see them clearly from this distance."

"How do we approach them?" Blanc asked.

"How about we fly and circle around them while this ship keeps their attention with distracting fire?" Vert pointed at spot away from the target.

"Good idea, Vert! You heard her, right boys?"

"Yes, ma'am!"

"Wait. While I support Vert's idea, I believe some of us should stay here to defend this ship from cannon fire," Noire gave objection by raising a finger.

"Good point. We are getting better with strategy and skill. This is our new ship. It would be bad if Four Eternal Hearts gets damaged during its debut…" Vert pondered for a while. "I think it would be good if at least one of us stay here."

"I will stay," Blanc raised her hand. "I think I am the best defender."

"Do you remember cannon ball training we went through?" Neptune approached and stared at Blanc.

"Of course, why wouldn't I? I scored highest when it came to blocking/ deflecting cannon ball, didn't I?"

"True, but by hair… anyway, good luck protecting Four Eternal Hearts! Hey, Blance! Do you want to make bet?"

"What?"

"If this ship remains without even scratch, I will give you my best pudding! Otherwise…"

"I will make my specialty for you, right?"

"Correct! Deal?"

"Deal."

Both of them grinned. After that, Neptune joined Noire and Vert.

"Ready?"

"Yeah!"

"It's time to show power of our unity!"

They transformed and started flying far enough not to be seen by the enemies. On the other hand, Blanc and crews readied their weapons. She checked on her hammer while others reloaded their guns and cannons. After looking around, she decided to transform as well just to be safe.

"Ready?"

"Yes, Lady Blanc!"

"Good. It looks like they already moved far enough," she inhaled deeply. "Fire!"

On her signal, the crews fired cannons at the unsuspecting ship.

*Boom!*

*Boom!*

Few shots landed on the enemy ship. Just like they expected, the enemy retaliated with their cannon fire. However…

"Not on my watch! Ha!"

Blanc brandished her hammer to strike each hammer.

*Slam!*

*Smack!*

She made sure no harm would come to her beloved ship. After that, she watched her sisters rushing to the enemy ship.

"I knew I could count on her!"

"Well, but you will lose bet and make a pudding for her," Noire smiled and leered at Neptune.

"I don't mind. It was already win win bet no matter outcome. She will taste my masterpiece. Anyway, let's kick their ass and claim our prize!"

"Agreed!" Vert shouted. "Sylhet Spear!"

A large spear popped up and thrusted toward her enemies.

*Crash!*

"Guaaaaa!"

"Aaaaa!"

The enemies were totally dumbstruck. Not even in their wildest dream, they thought some people would've already reached the ship after cannon fire.

"Enemies already got close!"

"How? Can they fly or what?"

"It looks like… they are Four Heart Sisters!" one of them pointed a finger at them and shouted.

"That's right! And we are here to take away your treasure!" Noire shouted "Tornado Sword!"

"Kyaaaaa!"

"Cross Combination!"

"Urgh!"

"What are you standing like idiots? Do what you are paid for!"

Mercenaries started attacking the trio.

"Take this!"

"Slow!"

Neptune casually avoided sword slash and countered.

"Kuk!"

"This is too easy," Noire smirked.

"Don't get cocky, you…"

*Slash!*

"Argh!"

"What did you say? Oh! Never mind."

"Hah!"

"Hmm!"

*Boom!*

When Noire blocked someone's attack, explosion occurred where she blocked. She pushed back.

"Huh~ You are pretty good. What's your name?"

"My name's Ideo. I am a boxer… and a mercenary on this ship. Nice to meet you."

"Pretty interesting ability you got there. Devil fruit?"

"No. Just my innate talent. I am glad I finally get to use my skill to test."

Ideo threw his punch at Noire again. But Noire swiftly sidestepped to avoid.

"Noire. Do you need help?" Vert asked.

"No. Go ahead and clean up the rest. I got this!"

"Don't push yourself too hard."

"Looking somewhere else?"

*Boom!*

She barely blocked his explosive punch.

"Tch!" Noire clicked her tongue. Then, she began her counterattack.

*Slash!*

*Swoosh!*

*Clash!*

Ideo avoided and deflected her sword with his arm. At the same time, he also thrusted his arms several times. It was intense battle. Neither side yielded or fell back.

"I am so glad I took this job," he smirked. "I get to fight worthy opponent like you. I don't care about gender."

"Oh yeah? Good to hear. But I am here for treasure."

*Clank!*

"Wow. That guy is really tough. Maybe, we should…" Neptune mumbled while taking care of weaklings.

"Let's respect her request and focus on fodders," Vert whispered her. "Rainy Ratnapura!"

*Tututu!*

"Kyaaa!"

"Step aside! Let me handle these two!" a very tall and bulky man stepped forward. He wielded a huge metal club.

"Neptune!"

"Got it!"

"Uryaaa!"

*Slam!*

The man slammed at them, but they easily avoided it. Within blink of eyes, they moved to his both sides, surrounding him.

"Take our combination attack!" Neptune raised her hand and summoned giant swords. "32-bit Mega Blade!"

"Sylhet Spear!" Vert also summoned giant spears from behind. "This is our combined might!"

"Blade and Spear!" Both of them shouted.

"Uuuurgh!" after receiving quite beating from them, he helplessly fell on floor.

*Boom!*

That was another support fire from Four Eternal Hearts. By the time all three glimpsed, their ship already got close here.

"You guys took all the fun. At least leave some for me," Blanc smirked as she jumped and landed on the ship.

"Follow Lady Blanc!"

"Uoooooh!"

*Bam bam!*

*Clank!*

"About time!" Neptune smiled and clenched her fist.

"I guess it's time to wrap up. Noire!" Vert waved her hand and shouted at Noire.

"I know!" Noire replied back.

"Tch, your reinforcement arrived," Ideo clicked his tongue.

"I am sorry to say this, but this ends now!" Noire kicked his belly and pushed him back.

"Kuk!" he coughed and tried to regain balance, but it was too late.

"Infinite Slash!"

Noire started dashing and slashing Ideo all over the place. She was literally circling around him.

*Slash Slash Slash!*

"Aaaargh!"

He desperately tried to block or dodge her attack, but he couldn't keep up with her speed.

"This is it!"

As soon as she finished her last strike and landed, blood spewed out from all over his body.

"Urgh…" Ideo collapsed on bloody floor.

"Don't worry. I am sure you will live. Hone your skill if you want a rematch."

After few minutes, everything was settled. Remaining enemies surrendered, and Big Mom Pirates crews tied them up.

"This was pretty much piece of cake," Neptune grinned.

"It's thanks to our training," Vert added.

"You guys took all the fun. Next time, I am going in," Blanc groaned.

"Sure… anyway, let's claim our prize and…"

Before Noire could finish her word, there was sudden explosion.

*Boom!*

"What the? Who is shooting?"

"W-we don't know, Lady Blanc!"

"Aren't we supposed to be only ones in this area today?"

"L-l-look at that! I-it's Chinjao family!" One of the henchmen shouted in terror.

"Say what?" Noire rushed to edge of deck.

"Chinjao? You mean that legendary pirate who is said to split an ice continent with mere head-butt?" Vert gasped.

"Just when I thought this was too easy…" Neptune gulped. "Oh no! Here it comes!"

Chinjao ships fired several cannonballs. Four Heart Sisters stepped forward and blocked them all.

While they were busy, the ships swiftly closed distance from the merchant ship. After that, one giant figure jumped high and landed on the merchant ship.

*Crash!*

*Rumble!*

"Uwooo!"

Many of them on the ship felt shock. Some of them landed on their butts because they couldn't keep balance. The ship violently shook. When the ship stopped wavering, all of them focused on that giant figure.

"Don Chinjao…"

"Hiyahohoho!"

12 tatoo above his left eye, general coat, angled beard… above all else… that weird pointy long head stretching all the way up… this man was definitely Don Chinjao.

"He looks pretty funny to be honest," Neptune giggled and whispered.

"Don't be fooled by his look. I am not sure we can fight him," Vert trembled and dropped sweat. "I can sense enormous power within him…"

"She is right. We better make our move first," Blanc gulped and readied her weapon.

"He may be a fearsome and legendary, but who cares! If we gang on him…"

*Clap!*

Don Chinjao clapped his hand.

"Come back after another training, you inexperienced younglings!"

"Uh…!"

Many of Four Heart Sisters' crews lost consciousness and collapsed on the floor.

"This is…!" Noire looked around.

"Conqueror's Haki!" Vert gasped.

"Hey, bastard! This is our treasure, so back off!"

"In world of pirates, strong takes all. That's the rule. I have also looked forward to this booty."

"Over my dead body!" Blanc rushed toward him.

"Blanc, wait!" Neptune tried to stop her, but she was too late.

"Getter Ravine!"

"Huff!"

Chinjao countered her special attack with his haki-infused fist.

*Clash!*

"Urgh!" Blanc couldn't endure the shock, so she was greatly pushed back. "My hands feel kinda… numb. Damn, he is so tough."

"Let's remember our teamwork. That's our strength," Vert glanced at Blanc and gave advice.

"Right. So let's attack him at the same time!"

All of them split and surrounded him. Then, they dashed toward him and brandished their weapons.

*Clank! X 4*

"You gotta be kidding me…"

"He blocked all our attacks!"

His two hands grabbed Vert's and Noire's weapons while his pointy head blocked Neptune's and Blanc's weapons at the same time. While they were dumbstruck, Chinjao quickly grabbed Noire and Vert and smashed them against Neptune and Blanc in front of him.

*Smash!*

"Kyaaa!"

"Kuk!"

They all groaned in pain. However, he showed no mercy.

"Hasshoken Secret Art: Drill Dragon Nail!"

*Crack!*

"Aaaaah!"

All four of them were sent flying to the treasure room. They violently crashed. After that, light engulfed them, and they reverted back to their normal forms.

"Ladies!" One of the BMP henchmen came to their side. He tried to wake them up by shaking them.

"They are all knocked out!" another henchman commented.

"No way!"

"But this is Don Chinjao we are facing… maybe, we should've brought other executives or Sweet Commanders…"

"D-damn it…"

"Hiyahoho! Is that it? Are those girls your captains? What rookies!"

The fight ended in instant. Although there was little and futile resistance from BMP crews, they were quickly subdued and tied by rope. Then, Don Chinjao's crews started taking all the treasure on the ship. It was after their crews took most of the treasure.

"U-uh… my head…" Neptune opened her eyes and shook her head. "H-hey! T-those are our treasure!"

"You lost. So I am taking all the treasure here!" Chinjao grinned as he oversaw transportation of the treasure to his ship.

"Why you!" she tried to move, but she realized that she was all tied up. "D-damn it…"

"D-don't get cocky! You will… pay for this! We will get… our prize… back!" Noire who also woke up shouted. She also tried wriggling to no avail.

He decided to ignore them. After loading all the treasure, his ships departed the scene.
