I'll be straight up, I looked at the fanfiction and read the ones about Ace. I guess I just felt like he deserved more love. He was an amazing character so this is going to be his love story with an OC. Yes I know OC stories aren't everyone's favorite thing but sometimes the real characters just don't match up well… I'd love to hear your comments questions and concerns.

Warnings: This fanfiction will contain language, gore, and most likely smut just because I like it ;)

Chapter 1

The youngest of the five princesses sat swinging her legs off a chair where her feet couldn't reach the ground. She absolutely loathed parties. She was far too young to do anything exciting at them. While everyone else could dance and eat she could do neither. Of course she could ask a servant or something to fetch her food but that had no meaning. If she couldn't do it herself she wouldn't ask someone to do it for her.

That was why everyone else in the castle though she was weird. Never had she asked for anything. Maybe it was because of all the praise she got from her father for doing things on her own. The attention she got from father was certainly why her sisters and mother hated her. Why else would she have to wear this hideous pink dress and do nothing on her seventh birthday?

"Princess Cassondra," a voice said. She turned her chocolate eyes up to a mysterious man. He was dressed in an overly fancy suit like everyone else at the part but he still had his top hat on. It was tipped over his eyes.

"Who are you?" she asked. Her doe like eyes tried to find his. All she could see was the friendly smile plastered on her lips.

"I'm actually a relative of yours," he answered. "That's why I brought you this."

He pulled out a sort of fruit with colors swirling all around its round shape. Cassondra stared curiously at it wondering what it was.

"This fruit is more delectable than candy," he informed. "I brought it a long way just for you. Won't you eat it for me?"

She thought about telling the man to buzz off but couldn't. She would surely be scolded for being so rude not to accept his request.

She took the fruit and slowly bit into it. He was right it did taste better than candy. However she couldn't see straight anymore as everything started to go black. She fell out of the chair and her people yelling. She vaguely wondered what for.

10 Years Later

"Princess Cassondra would you please hold still," the maid asked as she fumbled with the strings to her day gown.

"I have been telling you for years Claire you should call me Cassie," she replied. "You shouldn't even bother with the dress I'm going out right now anyway."

"Princess please don't do this today is a very important day," Claire pleaded. "You're engagement will be announced. Besides your mother would have a heart attack if she knew what you do outside of the castle."

"Oh please let that happen," Cassie muttered. "Then I could finally laugh at that old bitch."

"Princess your language!" Clair said appalled. "Just please don't do this."

"Too bad so sad," Cassie said as Claire finished lacing up the gown.

Cassie snarled at herself in the mirror. It resembled the dress she had worn on her seventh birthday. It was pink and pooled to the ground after proofing out. It had bows all over it that were just like the one that held her dark chocolate curly hair in its elegant ponytail. She grunted walking over to the window.

"Now remember Claire for this to work you can only report me missing in five minutes," Cassie reminded. She grabbed a small black bag by the window sill. "I'll see you later tonight."

With that she jumped out of the window. She heard Claire yell her name but she ignored it as she ran towards the castle walls after landing perfectly.

Oo00oO

Cassie cursed as she turned into the alley way in her pink dress. It was painfully obvious who she was. The castle guards had located her almost immediately.

Without delay she rid herself of the horrid thing and began changing. She pulled on a tight black tank top with matching shorts and a jacket. She strapped the black gun holder to her thy below her shorts. Then cursed.

She had forgotten her black boots. Now she was stuck with these frilly pink bow shoes. She truly hated her family. Ever since her father died she may as well be all alone in the world. At least Claire wasn't bad, but she didn't exactly support her.

Cassie undid the stupid bow holding her hair together and walked out of the alley. No one would ever suspect her of being a princess she was wearing clothes that were far too indecent and revealing for that. She was dressed like the run of the mill pirate. Just like a pirate would she headed to the nearest pub for some fun.

Oo00oO

Ace strolled idly around a small island that Whitebeard's ship had set anchor on. Apparently it was so small that it didn't have the marines on it. That was always a plus for a pirate.

However the town was buzzing to prepare for a birthday party for the fifth princess. Not that it really mattered to him he was a pirate and wasn't invited. He heard the speakers that paved the street switch on.

"Attention please attention! Princess Cassondra has once again escaped! I mean... err gone missing. Anyone able to locate her will be given an award! All men on standby are to immediately search. That is all."

Ace chuckled at the thought or a rebel princess it was quite amusing to think that anyone would escape from a castle; especially one with thirty foot walls.

Oo00oO

"Cassie I didn't think you would come," Jack said. His untamed red hair was in the way of one of his sterling silver eyes as usual. "Actually the whole island is looking for you."

"Well they should try harder then," Cassie said. She took a seat next to him at the bar. "You know with all the medical advancements you think they would find a cure for stupidity."

"Well my princess they call that poison," Jack said laughing. He remembered the first time he had met the princess. He had stumbled upon her changing in an alley. It was safe to say that his nose didn't heal for a few months after.

"Tch whatever," Cassie replied. "What are we doing today?"

"Well, me and my crew are going to loot off of Whitebeard's ship but I have no idea what you're doing," Jack said downing his glass of whisky before Cassie could take a sip.

"You need to take some poison because that is the stupidest idea you have ever had," Cassie said. Her eyes narrowed at him while he just smirked at her. "Going after Whitebeard is basically committing suicide."

"Does that mean you're in?" Jack teased.

"Of course I mean with the both of us at least some people will survive." Jack frowned slightly. As long as he had known her Cassie had never been afraid and he still couldn't scare her.

"You know you shouldn't go it's pretty dangerous," Jack informed. "You might not make it back to that fancy party they are throwing you."

"That's great then I won't have to meet my husband to be," Cassie said standing up. "Come on what are you waiting for."

He heard the clunk of her shoes and looked down. He couldn't stop himself from laughing. Cassie growled and sent a glare at him.

Oo00oO

Ace was in his bedroom lying idly on his bed. He had been completely bored after he saw all that the little island had to offer. A good portion of Whitebeard's crew had gone drinking but he had chosen to stay behind with the remaining members. It's not like much could happen here.

He closed his eyes slowly drifting to sleep. Maybe something good would happen later.

Oo00oO

"So does everyone understand the plan?" Jack asked his crew. He heard their agreement and glanced at Cassie. He concluded she looked too excited; she probably needed to get out more.

As the rest of the crew headed to prepare for the surprise attack Jack grabbed Cassie by the arm and turned her to face him.

"Remember you stay by me at all times," Jack ordered. She nodded her head.

"I know," Cassie said. "If I die there is no hope for this island to remain sane with its messed up monarch women. Although you know very well I'm capable of handling myself.

"How could I not when you remind me every few minutes." He ruffled her hair. "It's good that you're around to keep me in check princess."

"Whatever," she muttered before getting into position.

Jack gave the signal and she watched the other members secure ropes onto the deck. She could already hear the crew reacting. Jack gave her a nod and she leapt onto the rope landing perfectly. She raced up it like she was a professional tight rope walker. Jack was right behind her.

She looked for the magical bored that could be lowered down to let the rest of the crew; however she was already defending herself against the sea of men that came at her. She pulled took out her gun.

"Elli Elli berry wind shot!" she called. A bullet made entirely from air shot out and cut the ropes holding it up. The wooden draw ramp lowered to the ground. Jack's crew raced up eagerly joining the battle.

Ten minutes later she was back to back with Jack completely surrounded. Jack's men had retreated like he had told him to. They didn't get the luxury since they had been taking most of the heat anyway.

"Jack you're an idiot," Cassie said. "I hate you."

"No you definitely love me," he said laughing.

"Just what made you wake up and think 'I'm going to get myself killed today'?" Cassie asked.

"Well honestly I waited until I heard Whitebeard left the ship to attack," he said with a smile. "Turns out they're still strong."

"So you're not only stupid but a coward," Cassie muttered. "I need to get better friends."

"Who are you kidding Princess? I'm your only friend. Let's use one of our famous combos."

"Oh my god, you totally got us in this situation just to use it. You asshole!" Cassie exclaimed with a playful smile. "Which one do you want to use?"

"Hmm the one with water would be pretty fun. Even though we didn't get anything it will leave his ship trashed."

"And get us electrocuted. Pick again smartass."

"Fine Fine. How about we propel ourselves off using fire? That should be safe and logical enough."

"Sounds cool to me." Cassie held her gun at the ready as she climbed onto Jack's back.

"You mean it sounds hot," Jack said. Cassie rolled her eyes she just knew he had winked.

"Get on with it already," Cassie complained. He laughed before becoming serious.

"Shock Shock jolter!" Jack practically whispered. Electricity flowed through his boots as he jumped.

"Elli Elli fire shot!" Cassie yelled not being discrete about it.

Fire poured from her gun lighting the ship ablaze as it pushed them further into the air along with Jack's electrical current. Her shoe slipped from her feet unnoticed.

It took about forty-five seconds before they landed securely on the dock watching the ship burn and the crew systematically put out the fire.

"You know now that we damaged their ship they will have more time to hunt you down," Cassie said with a glance towards Jack.

"It's whatever," Jack said with a smirk. "Well my Princess I'm afraid it is time for me to depart once again. I hope you have an enchanting night at your party. I also hope I have made your birthday enjoyable."

"My birthday has always been more of a tragedy than a celebration," Cassie said. "However seeing you ultimately fail has made it a little better. I will see you when I see you."

Jack watched as Cassie more than likely started walking back to the palace. He felt bad for her having to live there; it didn't suit her. Cassie was wild, sarcastic, and not proper in the least. Yet she was forced to be tamed, polite, and lady like since a young age. Jack knew a day would come when she would just snap.

It was a day worth looking forward to.

Oo00oO

"What the hell happened here?" Ace asked. He had awoken to the smell of burning wood and discovered it was Whitebeard's ship.

"A small group of pirates attacked us," a crew member said. "They weren't very strong except for two of them. They were devil fruit users."

"Why didn't you wake me," Ace said shaking the man by the shoulders.

"Sir you get cranky after your naps," one chimed in. "No one wanted to get burned again."

"I'm so dead," Ace muttered.

"You are, but not yet," an all too familiar voice said from behind him.

Ace turned around to see the captain of the ship, Whitebeard. He stood there strong and powerful, like he always did. Ace had already come to accept his position on Whitebeard's crew, but this wouldn't look good for him.

"I want you to find the culprits and pay for the damages," Whitebeard said after glaring at Ace a little. "Until the ship is fixed I'm afraid we won't be going anywhere."

Whitebeard walked off the deck and most likely to his chambers. The rest of the crew began to talk about what had happened.

Ace walked around the deck scanning the charred areas, some looked more like they had been electrocuted. He sighed until he noticed something out of place. It was a dainty pink shoe with gaudy bows on it. He picked it up and examined it. In the sole there was something that couldn't be mistaken.

It was a royal emblem. Ace just figured out the case of the missing princess.

Oo00oO

A loud smacking noise echoed through the room. The servants held back their pained expressions once again. This had become a routine thing exactly five years ago when the king had died. The youngest princess, the scandal child, was always punished severely.

Cassie clenched her fists in anger reminding herself she couldn't lash out at this woman. Her "mother" so to speak was the queen. It would be inappropriate conduct to wring her bony little neck.

The Queen Alice was beautiful with golden hair and pretty sky blue eyes. Cassie could see what her father saw in her but it hadn't been enough. Otherwise she wouldn't exist. He had to have seen something in her real mother though.

"You ungrateful child," Alice sneered. "How dare you sneak out of the castle? I have provided for you even though you are not my own. We have a very important guest coming for your birthday. Your husband to be, Prince Haru."

"What?" the eldest of her sisters Ashley asked. "Why would the most handsome prince want to marry her when there are all of us?"

Cassie rolled her eyes as her sisters all began to question each other and agree that she wasn't good enough for him. She also noticed how her mother wholeheartedly agreed with them.

"I want the wall raised another five feet," the queen ordered. "Cassondra I expect you to be dressed and ready for your party. Get on now and don't disappoint me."

Cassie turned around biting her tongue from delivering a sly insult before walking out of the room.

Oo00oO

"Princess do you hate it here?" Claire asked tightening the corset lace at the back of the new dress.

Cassie would admit she liked this dress better but not by much. The light pink color was to be expected. The corset top was boned and had crystals placed all over it. The skirt was so poofy out so much that it was almost like a table top that had crystals gathering and creating layers on the dress.

"I do hate it here," Cassie answered. "However I know that some people would prefer if I were not to leave the royal family, my father was one of those people."

"Oh I see…" Claire said softly. She felt sorry for the princess she was different from of the rest of the family, but Claire though she was different in a good way. "You are completely ready. Your entrance to the ballroom will be soon."

Cassie excited her chamber and began the descent down the stairs. They just had to stick her in the highest tower out of the way of everything. However they had yet to figure that was why escaping from the castle was so easy. Cassie would never tell them that though.

Cassie paused at the entrance to the ballroom. She could hear the orchestra playing a song she didn't care about and the chatter of the hierarchy of the island plus other invited guests.

"Princess Cassondra Hart has arrived," a page announced.

The ballroom was silent as was expected as Cassie slowly walked to the grand chair she was only allowed to sit on this day of the year. No one would clap for her like the other princesses it would earn the bad grace of the queen.

Cassie sat down and watched as the ballroom once again filled with good natured laughter and small talk which she couldn't participate in. She noticed a familiar face walking towards her.

He was different than usual more put together. His red hair was usually untamed but was now neatly slicked back and he wore a suit.

"Jack, how did you get in here?" Cassie asked. He looked at her and smiled.

"I see why you can escape so easily," Jack commented. "The security in this place sucks. Getting in here was easy. If you weren't you I would afraid you would be assassinated."

"Nice to see you're concerned," Cassie said. "You can stay but I don't want you to close to me right now. I'm a princess if you're discovered you can say good bye to that head of yours."

"Easy there," Jack said. "I'll go enjoy the free food and women then. It's too bad you aren't one of them." He left before Cassie could say anything back about his comment.

Cassie noticed one of her sisters walking towards her. of course she was dressed in a gorgeous pale yellow form fitting gown. Her name was Alayna she would admit she was the sister that didn't bug her as much as the others.

"Cassondra," Alayna spoke. "I want you to get married to this prince. He can take you away from here. It is not because you're an eyesore but you could be happy without mother. That would be what father would want the most your happiness." Cassie managed to smile at the woman before she walked away from her.

"Prince Haru is now entering," a page yelled.

Cassie wasn't watching for the prince as much as she watched the people before her. They had all gone silent, but it was different from when they had gone silent for her. If she had to guess what it was for than it was out of fear?

Cassie finally took a look at the man. She had to stop the shiver that climbed her back as she looked at him. He was strong and it was as if she could smell the blood on his hands. He was at least a warrior who most likely hadn't lost a single battle. Not only that but he was strikingly handsome

He had eyes as dark as night with pale skin and shiny silver hair that framed his face perfectly. His body was covered in black and red armor but she could tell that it was lean with muscles. He had broad shoulders which only severed to add to his strong presence.

When he reached her he bowed on one knee before her taking her hand.

"Princess Cassondra I greet you," he spoke deeply. He kissed her hand before releasing it. "I have brought you a gift, that I believe suits you."

He pulled a black satin box from a place Cassie didn't know existed. He opened it and revealed a sparkling necklace. It had tears of diamonds that were accented by large rubies. It was beautiful but something Cassie would never think of wearing.

"Thank you Prince Haru," Cassie said in the sweetest voice she could manage.

"Anything for my wife to be," he replied suavely. "Would you care for a dance?"

Cassie didn't have to turn around to see that the queen and her sisters were glaring heavily at her.

"I'd love to," Cassie answered. She didn't care if the others were relieved or absolutely furious, she just wanted something to do.

They began dancing to the music. It was a basic waltz Cassie could accomplish it easily and so could Prince Haru.

"So Prince Haru…" Cassie started.

"For you its Haru," he corrected. Cassie sighed before meeting his eyes.

"Haru then," Cassie said slightly annoyed. She could tell he picked up on it by the smirk on his face. "Why do you want to marry me?"

"That power you have is very much in my interest," Haru replied. Cassie looked at him shocked. "Ah don't seem so surprised. I have been keeping tabs on you since you were around ten. I know everything."

"Is that so?" Cassie arced an eyebrow at him.

"Yes it is." Haru had an almost deadly look on his face. "I want you to stop going out of the castle or I will tell your mother what you do."

"Enlighten me," Cassie taunted. "How would you know what I do?"

"I have informants everywhere," Haru replied. "Like right now I know you're little friend is in this room. I wonder if his blood would be as red as his hair."

Her body stiffened at his words. He did know. That was shocking. Why would he know? Why would he care?

"You will not hurt him," Cassie ordered. Her chocolate eyes were beaming with passion and Haru couldn't hold back a deep chuckle.

"I want to make a request that you wear red," he mused massaging the small of her back. He ignored the warning noise that sounded from her mouth. "It would suit your much more passionate side. I hate submissive women."

"Really that's great," Cassie said sarcastically. "I just hate you."

Oo00oO

Ace had snuck into the ballroom fairly easily dressed in finer clothes than usual. He had even bothered to put a shirt on. He was also surprised that it was obvious who the shoe belonged to.

The fifth princess could only be the girl in the enormous pink ball gown. She was currently dancing with who assumed to be her fiancé. She didn't look happy at all.

She looked angry as if she wanted to murder the prince on the spot. As soon as the dance ended they both bowed to one another keeping up the formal act.

That's when Ace made his move before she could sit down. He had practically darted to the other side of the room to catch her.

"Princess," he said as he grabbed her wrist. She turned around obviously shocked at his actions. He released her wrist immediately realizing he shouldn't have done that. "I was wondering if you would like to dance."

Cassie eyed him curiously wondering why this man was breaking the almost unspoken code that was not to engage her in any other way. Then again if he was like Prince Haru and could kill all of them she would understand his daring nature.

"I would be pleased to do so," Cassie answered. She held out her hand hesitantly before he took hers.

To her surprise he was smiling. Maybe grinning was a better way to describe it. Cassie noticed that his suit was a bit cheaper than everyone else's and his shoes weren't shoes, but rather boots. He also had on an informal necklace. His hair was slightly messy and greasy but she thought it added to his charm, as did the little freckles across his face.

They began swaying to the music and Cassie let out a giggle before smiling at the guy.

"You're not rich or a noble are you?" Cassie finally said. She could tell he wasn't very comfortable dancing, or very confident either. He smirked at her.

"You're right I'm not," he said. "What gave it away?"

"Hmm I would have to say when you asked me to dance," Cassie answered. "What's your name? I'm…"

"Princess Cassondra," he completed. "You can call me Ace."

"In that case you can call me Cassie," she said. She was surprised how comfortable she felt with this man. Maybe she got a sense of superiority since she knew he was below him. "Now I have to ask what you want with me."

Ace was surprised at the firmer tone her voice had taken but tried not to show it on his face. He looked at the girl closer. Her chocolate eyes and hair, to her slim golden brown frame made her seem innocent. She didn't look like she could burn a ship.

"I need you to pay for damages to a ship you destroyed earlier today," Ace said. He watched a number of emotions run through her eyes before she smiled; he thought it seemed a bit sly.

"How could I, a princess, do damage to a ship?" Cassie questioned. Her eyes were filled to the brim with excitement; Ace didn't miss that detail either.

"How could a royal shoe end up on the ship that was damaged?" Ace said smartly. He watched as the girl sighed, before pouting.

"Well do you really need me to pay for Whitebeard's ship?" Cassie asked. Ace didn't bother masking his shocked expression.

This girl had attacked the ship of Whitebeard, and knew who she was attacking.

"Are you crazy?" Ace asked. She smiled up at him.

"I have two friends," Cassie explained. "One is an overly safe maid and the other is a complete dipshit. I was with the dipshit today."

"You probably shouldn't use that kind of language," Ace grumbled. "About the damage…"

"I got a gift to extravagant for my tastes today," Cassie cut in. "I'll give it to you to pawn at the next island to get supplies. It's about two miles southwest; I have swum to it before. It's a port island many merchants are there. Use a fake name in case you are to get caught otherwise things will get messy. I won't save you only claim you are a thief."

"You're merciless," Ace said looking down at her. A smirk met his blank look.

"If you live in this palace it is a necessity," Cassie said after a while. "My room is the highest tower I'm sure you can find it meet me there at midnight."

"Do you always invite strangers to your room?" Ace teased. She smiled lightly at him.

"Only the ones I find interesting," Cassie said. The song ended and she cast him a look. "I'd watch yourself if the rumors are true my fiancé has quite the temper and he doesn't look to happy right now."

Ace glanced at the prince and she was right. He didn't look happy, he seemed angry. Ace smiled sheepishly at the prince but was met with a scowl. He decided he'd leave now while he was ahead.

He turned to wave good bye to Cassie who just gave him a blank look. She wasn't used to people being so nice upon a first meeting. Ace was refreshing to her.

Oo00oO

Well that is the first chapter. I know Ace was a little OOC but pretty soon you will get to see his redeeming qualities like how caring and responsible he is. Cassie seems a lot less hmm… snobby as her strong sense of justice is shown as well as her loyalty.Leave a review otherwise the next chapter probably won't be out for a long time!
