I do not own One Piece
As this is an AU clearly this filler has absolutely nothing to do with the story line. However, that being said, if ya'll like this particular AU perhaps I can make multiple parts to it. I hope you all enjoy! Also, as this would be the first part, it'll be a bit slower paced than some other mafia type AU's. Especially since this is more of Katsu, who will be called her birth name as Mitsu, will be meeting the Straw Hats. If you guys do happen to like where it is going, then like I said I'll add another part later on.

3rd Person POV
.................................................................
A katana rested at the neck of a shaking man. His eyes were wide as he looked up at the red haired man that held him down to the ground with his foot. He had known the risks that spying for a rival yakuza, specifically those that lead to him getting caught.
"P-Please-"
The man pressed his foot down harder onto his chest. "Eh? You're begging for me to let you off easy?" His blue eyes narrowed and as he leaned down to sneer at the quivering man his red hair pulled out from the ponytail and into his face. "You're the one that just walked into my sister's room."
"I- It was an accident! Please I-I swear! I'm new!" The man cried looking up at the red haired male. Standing over him was Sato, the nephew of Shanks who was the leader of one of the largest yakuza groups in japan. The man was not prepared for the nephew to be as terrifying as he is. Especially over walking into the wrong room!
"That's not an accident that can be allowed." Sato frowned, removing the sword and reaching down to pick up the crying man by the collar of his shirt. Removing his foot, he began to drag the man down the hall. "I can't get blood in front of her door, so we'll move you somewhere else."
"W-Wait! No!"
Walking down the hall Sato paused as he recognized two other figures walking down the hall. Their eyes traveled down the the man Sato was dragging and they raised an eyebrow in question.
"Isn't that the new member?" Makoto asked, pointing down at the crying man. He was dressed in a black suit, though the black tie hung around his neck loosely. His blue hair was slicked back for the most part, a few stubborn strands had managed to fall forward into his face. "What's he doing on this part of the house?"
"I-I got lost-!"
Sato kicked the man's face, halting any excuse from escaping him. "He walked into Mitsu's room."
The air stiffened as both males paused, their eyes now glaring down at the man.
"While she was in there." Sato continued.
The man could already see the light.
"While she was changing."
The man tried to call out a protest at the last comment. He was sure whoever this Mitsu person was had not been present in the room, and she surely had not been changing when he walked in.
Before he could utter another word of complaint, a new person was pulling him up. This time, however, it was the person he knew he needed to fear. The red haired man glared down at him.
"Oh, so you just need to die then." Shanks answered, his eyes nearly white with rage. "Sato, you go check up on your sister. Makoto and I will take care of this pest."
Sato bowed, placing his sword back. "Of course, Uncle."
Without another word, Shanks began to drag the spy away with Makoto following after him. Sato waited a moment before turning and walking back towards his sister's room.
He straightened out his black yukata and ensuring that his sword was out of sight. Raising his hand he knocked on the door, waited a moment then began to open the door. "Ne, Mitsu-chan-" Sato froze, blinking as he looked at Mitsu.
Said female froze as well at the sight of her brother. She was still half way through the window. Her long hair, which was typically neatly brushed and styled, was messily pulled into a ponytail. Even the pink yukata that Sato had seen his sister in earlier had been changed out to a blue poncho and shorts. He assumed she had lost her shoes, given that her feet were bare.
"Uh..." Mitsu cleared her throat, still hanging half way in the window. "Sato. I was..." She looked down at the window then back at her twin who was staring at her dumbfounded. "I was just testing the window." Pulling herself back into the room and closed the window and nodded tapping the glass. "Yup, it really works well. I can see the extra money Uncle put in it."
Sato looked at the window, then looked back at his sister. "Testing the window..." He mumbled, "This is why we have to watch over you." He shook his head sighing softly. Walking into the room he looked over his sister. "That guy didn't scare you did he?"
Mitsu frowned in confusion, "Eh? What- Ah! Y-Yes. It was pretty scary."
She had absolutely no idea what her brother was talking about. However, given he was walking into her room without waiting for her to give the okay, she assumed something had happened.
Sato nodded in understanding, "No worries, Mitsu-chan. Uncle and Makoto are taking care of him right now." He reached his arms up to give Mitsu a hug, the sleeve of his yukata rose showing a sleeve of tattoos covering his arms. Mitsu shrugged and moved forward to give her brother a hug back.
"Also," Sato said, his smile widening as his eyes narrowed into a threatening glare down on his sister. "Mamoru sensei said you skipped class." Mitsu froze, feeling the air stiffen up. "Again."
Immediately he began to pull at his sister's cheeks making her whine in complaint. "You can't be missing classes."
"Sato! Stop!" Mitsu complained, pulling at his wrists as he pulled at her face. "It was just history!"
He released her face and placed his hands on his hips scowling at her. "Mitsu, Uncle already said that if you did that one more time you're going to have to go to school."
Immediately Mitsu brightened up, a slight bounce in her step as she nodded. "Yes! I wanna go to school with you and Makoto! It's not fair that I'm the only one that gets stuck here at the house!"
"It's dangerous!" Sato exclaimed, shaking his head. Somehow he had thought that was going to be a threat, but he should have remembered how his sister is. "The whole school is filled with different gangs and different yakuza members.-"
"Law goes to school with you two too!" Mitsu smiled, bouncing on the balls of her feet. "Oh! Does Luffy go there too? I haven't seen him in years!"
Sato groaned at the mention of the hyper child his Uncle had taken under his wing for a year. Luffy had gotten along with Mitsu exceptionally well, better than he got along with his own twin. He just knew if the two of them got together it would bring disaster.
Surely his Uncle wouldn't keep the deal.
....................................................................................
Sato and Makoto scowled at their Uncle as Katsu came bouncing down the stairs in her new school uniform. Their uniforms all matched, though Katsu wore a skirt instead of the pants the brothers wore.
Shanks was chewing on his fingers as he watched Mitsu rush towards the brothers. "Ah, maybe I made a bad decision..."
Makoto took off his yellow blazer and placed it over Mitsu. Sato rolled his eyes and began to fix the black tie around her neck, which was hanging too loosely. As soon as Sato finished, Makoto began to button the blazer.
Mitsu frowned at her brothers as they began to try and nitpick her uniform.
"Leggings! She needs leggings!" Shanks called out.
Both Sato and Makoto nodded in agreement. Just Benn came out with a pair of black tights, Mitsu held up her hands.
"No. That's enough." She sighed as she began to unbutton the blazer Makoto had put on her. She had already refused to wear the one they provided for the girls, and she knew it was optional. "I will not be needing any leggings. I will not be needing this, Makoto. I am fine."
"Right, we'll be with you all day-"
"What?" She looked to Sato with wide eyes.
"Yeah! No worries, Mitsu-chan!" Shanks called out, "I made sure the school put you with your brothers, so no need to feel worried! They'll make sure nothing bad happens!"
Mitsu sighed out, nodding her head towards her Uncle, and began walking. Of course both brothers gripped her arms and steered her in the opposite direction.
She winced slightly, making sure to hide it enough so her siblings wouldn't notice. If they did, it would just raise questions as to how she managed to get so many bruises. She wasn't going to tell them of how she's been taking fighting lessons from Mamoru's older sister. Both her brothers and her Uncle were extremely overprotective over her.
It was suffocating.
So when her Uncle had made that threat that if she kept skipping her tutoring classes with Mamoru he would put her into school, Mitsu took every opportunity to skip. If anything, she's taken it as stealth training. She can sneak out of just about anywhere now.
Now, he's finally made true to his threat. She was going to finally get to go to real school, where she just prayed she would get into a fight. Or she could actually make some friends. Sure she's friends with Law, but for the most part he was quiet and too secretive. She needed to make more adventurous friends.
Even if her brother's didn't approve.
........................................................................
A loud yawn sounded from the moss headed male. He would have skipped class again if it hadn't been for Robin forcing everyone to participate in schooling. Even then he debated on skipping, however their leader made it clear that they were to listen to Robin. Though he suspected Luffy had ordered them to listen to Robin because of the fact that their positions were being threatened.
So atlas, here he was, sitting in the back of class listening to the teacher drone on and on about the morning announcements. He glanced towards the door as it opened and the two brothers which Luffy talked to often walked in.
What were their names again? Pato and Maka? That didn't sound right.
He blinked when another person entered right after the brothers, from her bright red hair to the fact that she entered in with the two brothers, he didn't have to wonder for long on who the female was. Her eyes traveled around the room, a bounce in her step as she looked around excitedly. For a brief moment her eyes met his, she grinned at him before looking away.
She reminded him of a puppy.
"We have a new students joining us," The teacher called out, "This is Mitsu, please take care of her."
Before Mitsu could utter a word towards the class, her brothers each grabbed her shoulders and began to steer her towards their desks, which happened to be in the back.
Moving away from her brothers, she sat in the spot next to the green haired teen. Looking at him she grinned and held out her hand.
"Ah, I'm Mitsu!"
He looked down at her hand then back at her, her hand looked too tiny yet he noticed some calluses on them. For a girl which he knew must have been sheltered how could she have developed those? A smirk formed on his face as he placed his hand in hers.
"Zoro.-"
His eyes widened as she pulled him closer, her strength coming unexpected as she looked as strong as a twig. Her eyes widened as well, though he was sure there were sparkles surrounding the female. "You're really handsome, can I draw you? I haven't had the chance to see such a good looking model!"
As Zoro's face exploded red and he lost his ability to speak, her brothers were busy sending death glares towards him. Thankfully, Zoro didn't scare easily.
"Yosh!" The door to the classroom banged open as some more students filtered in. Those students being Zoro's leader as well as some blonde which looked as if he had gotten beaten up. Zoro wanted to snicker at the fact that Luffy had beaten up Bellamy again, though he found himself unable to speak as he realized he was still being pulled down by the new girl.
"You're late-"
"No need to worry." Luffy waved his hand dismissively towards the teacher, making her sigh as he walked towards Zoro. "Yo, Zoro, I beat up Bellamy again. Eh?" The black haired teen paused and tilted his head as he looked at the female holding onto Zoro's hand. "Who're you?"
Mitsu let go of Zoro's hand and turned to give her attention towards the new person. However, she was caught short as Sato stood in front of her. "Oi!-" Around the same time Makoto pulled Mitsu to her feet and began to drag her out of the class.
"Absolutely nobody you need to come in contact with." Sato stated.
"You know what, we completely forgot to get your supplies from the front office." Makoto smiled, steering his sister out of the classroom.
Mitsu looked up at her brother with a frown forming on her face. "Oh did we now?"
Her brothers were suffocating her.
............................................................................
Perhaps it should have concerned Mitsu how easy it was to slip away from Makoto. They had been walking down the hallway together then next thing she knew she was by herself in a completely different hallway of the school. Perhaps her brother had taken a wrong turn?
Either way, she shrugged and took out some of her spray paint cans, which she keeps in her backpack. Given that this hallway was empty, and the school lacked both artistic value and cameras, she figured why not place some color in the hall.
She had been hoping her brothers would leave her alone at some point in the day so she could get the chance to really showcase her talent. Just marking random parts of the city wasn't cutting it. She wants to see people's reaction to the art.
Humming to herself quietly, she began to spray the wall. Changing colors quickly and smoothly, she had already laid out the outline and was finishing up the coloring. To ensure she didn't get caught in the act she simply just put the name down with a couple of doodles around it.
Smiling at the art she slipped the cans back into her bag and started walking down the hall. That had been even easier than she had thought. Now she just wanted to see how long it would take for everyone to talk about it. She suspected it should be soon, given the school was filled with different yakuza members and they were always threatened by a simple possible gang mark.
What she had missed, however, were the two females that had witnessed the graffiti being painted on the wall. They remained silent, one watching as the female had skillfully marked the wall and the other timing how long it took her to finish the job. When she had walked away having taken only five minutes, they were both impressed.
For the raven haired female it was the tag that had finally caught her attention. In big bold letters the name, 'Katsu', was painted on the wall. The very name that had recently caught her attention as well as many others.
Especially their leader's, Luffy. He had been the most interested simply because the name had been drawn over another yakuza's symbol. She also remembered that he had commented on remembering that name from a game he used to play when he was a kid.
"She did that so fast." Nami mumbled, looking over the paint.
"Well, we finally found out who this Katsu person is." Robin mused, a smile playing on her lips. "I didn't expect it to be the Yakuza's Red Haired Princess."
Nami hummed in agreement, "Rumors were that she's extremely sheltered. I wouldn't have thought she would do this."
Robin's smile grew wider as she crossed her arms, "I wonder what else she may be hiding."
.............................................................................
The end of school was both a blessing and disappointing for Mitsu. As soon as she had managed to lose Makoto earlier both of her brothers had gone on the hunt and found her. From that point on they hung around her the entire time. She didn't get the chance to slip away anymore, it was hard to when both of them held onto her arms anytime she moved to walk.
She had also not had the chance to actually socialize with anyone, therefore she was leaving school with the same amount of friends that she entered with. Zero.
That also meant she hasn't gotten word as of if anyone has talked about the art she left on the wall. After she sprayed over Big Mom's tag weeks ago she could have sworn her art was supposed to have skyrocketed. Perhaps she had been wrong.
"Oi." Katsu stopped as both of her brother's came to a halt and moved to stand in front of her. She stood on her toes to try and see over their tall figures, but all she could make out was some tall standing red hair. "You two were on my turf last night."
"You're too insignificant to have any turf, Kid." Sato replied.
"Plus, you left some garbage on our land a week ago." Makoto added.
"Did you just call me insignificant?!" Kid growled, taking a step forward, his friends Killer and Heat taking a step forward with him. "You're the insignificant one. Relying on your big shot Uncle for power. You're too weak to make your own name."
Sato stared up at Kid, who towered over him, and shrugged. "Anyway," He looked back at Mitsu and smiled. "Let's ignore the non-recyclable trash, come on."
It was then that Kid made eye contact with Mitsu. He blinked, then a big grin forming on his face as he shoved a finger towards her. "You're the spoiled princess that they work so hard to protect. Uncle finally let you out of the tower? I suppose he had to keep her locked in there, given her looks-"
Kid was caught off as a fist landed in both his stomach and his face. Both Makoto and Sato stood over him as he had fallen to the ground, their eyes glaring down at the teen.
"You don't speak of my sister." Sato spat.
"Nor do you look in her direction." Makoto glared.
Mitsu looked on with wide eyes as an all out brawl started between her brothers, Kid, and his friends. She stood back and watched as they began to fight, but she dropped her bag as soon as she saw metal drawn.
Kid had pulled out a knife, and was preparing to slice at Sato while he was preoccupied with Killer. Immediately Mitsu dropped her bag and rushed forward. She didn't have a weapon of her own, but she did had some spray cans.
Jumping in front of the weapon, Mitsu jabbed the spray can down on the knife. Kid cried out in shock as red paint began to spray all over him. At the same time, Mitsu twisted the can with the knife in it. Freeing it from Kid's grasp, she tossed it off to the side.
Then, while the moment of surprise was still on her side, she pushed out her leg and kicked Kid's stomach as hard as she could muster. He fell backwards onto his butt with a loud thump.
The surprise of her lashing out had made the fighting stop all together and all eyes landed upon the female. She had not only landed Kid on his ass, but she had done so while also covering him completely in red spray paint and not landing a single drop on herself.
"Don't ever touch my brothers again." Mitsu ordered, glaring down at Kid. "Say all you want about me, but you mess with them and I'll make sure you'll be shitting red for a fucking year!"
When Kid moved to attack Mitsu, he was quickly shoved back down. This time not by her brothers. Instead it was by two different individuals, none of which Mitsu recognized right away.
"Did you really think it was okay to lay a hand on a princess?" The blonde glared, his leg outstretched ready to kick Kid down.
"You're three times her size!" The black haired teen complained, a familiar looking straw hat on his head. "Back off Kid!"
Sato stood up, having now knocked out Killer. He glared at the two males that had come to defend his sister, his eyes glaring down on Luffy. For now all he could do was hope that Luffy's terrible memory came into play and he didn't recognize Mitsu.
Stepping forward he turned his glare towards Kid, "I think you want to back down for today. Take your people home." Without another word, Sato tossed Killer towards Kid.
Grinding his teeth in anger, Kid stood back up and grabbed his friend. He turned his glare towards Mitsu, who returned his glare with one of hers. "You're gonna be next." He growled quietly before turning and walking away. Heat shoved Makoto away before following after Kid with a huff.
Before either brother could turn to smother their sister with concern, Luffy jumped in.
"Oi! You're Mitsu!" Luffy grinned.
Sato groaned loudly, his hands slapping his face. Of course his luck would run out here.
Mitsu blinked, then her eyes widened and a big grin formed on her face. "Luffy!"
Off to the side, three more individuals stood. Nami, Robin, and Zoro. Robin's eyes were on the ruined paint can with a knowing smile on her face, one which she shared a look towards Nami. The whole specifically showed Robin that there was far more to Mitsu than was put out.
Zoro blinked, looking down from the spray can to the female that was smiling widely towards their leader. A grin formed on his face, "So, she's a fighter." He mumbled. Those moves she had pulled were calculated, they weren't sheer luck. He didn't waste another moment and began to walk towards the small group.
"Who would have thought that the so called princess would be able to fight?" Zoro smirked.
Mitsu turned to glare at the person who made the comment only to pause then smile. "Oh, you're the hot guy from before. Ah, did you change your mind and decide to allow me to draw you?"
"Join us!"
Everyone around the group froze to look at Luffy. The teen was grinning widely, bounding on his feet as he looked at Mitsu.
"Hell no-"
"Mitsu!" Luffy shouted, holding out his hand towards the red haired female. "Join my gang! We're gonna take over Japan as the leading Yakuza!"
Mitsu paused, her eyes widening. She looked down at Luffy's outstretched hand. Surely this is what she had wanted? This could actually give her some freedom from that suffocating house. Sure, she knew her family had a reason to be so overprotective at times, but she was old enough to take care of herself.
A grin formed on her face as she slapped her hand down onto his. "Yes!"
........................................................................................
End of the Yakuza AU!
I know it wasn't completely filled with the whole mafia theme, but I think this is more of the intro. As an apology, here's a picture of Katsu in her school uniform?
This is not edited.
