"(Naaaaaaaame)!!!" Luffy whined, head in his hands dejectedly.

He's been at it ever since he woke up ten minutes ago. You felt a little bad since you were the reason why he passed out in the first place.

"Gomene, Daddy Luffy, but Hancock-chan seemed really friendly!" You beamed up at him.

Luffy looked up to see your adorable grinning face. It wasn't fair.

Ace smirked, he knew his little brother couldn't get upset with you when you look at him like that. You were also naive and overly sweet, so your intentions were nothing but innocent.

Sabo muffled a laugh behind his hand as Luffy's eyes went wide. "Hancock-chan?! YOU'RE CALLING HER -CHAN NOW?!" He asked in shock.

You blinked and tilted your head to the side cutely. "Yes?" You replied. "She says that because I'm your daughter, we're best friends now!" You puffed your chest out proudly, showing off the Luffy Fan Club pin on the blouse Hancock had bought for you earlier.

She absolutely adored you and somehow liked Law, sort of, that she gave you both free clothes from the department store of Amazon Lily. "I don't get why you don't like her, daddy, she's so nice!" You pouted up at Luffy.

Up to this point, Luffy practically wanted to kill himself right then and there. He plopped back down on the infirmary bed and groaned in defeat.

Ace laughed and ruffled your hair. Man, he loved you more and more every single day!

"Your daughter just joined the fan club founded by your greatest stalker." He teased, glancing over to Sabo. "I wonder what that green-haired fanboy would say when he finds out that Luffy has kids."

Sabo chuckled and folded his arms across his chest. Poor Luffy was so famous that he even had to deal with fakers who pretended to be him.

"You're talking about that Bartolomeo guy, right?" Sabo smirked. "I imagine him following them around like a royal bodyguard."

"Or an overprotective nanny?" Ace laughed again.

Luffy frowned and glared at his brothers.

They're. Not. Helping.

Glancing over to his other adopted, he blinked rapidly and sat up abruptly. "Tra-Guy... What are you wearing...?"

All eyes turned to Law. He was sitting there with a blank expression on his face as usual. He wore a yellow and black hoodie and a pair of jeans, but that wasn't what Luffy was concerned about.

Law smirked smugly and tapped the pin on his chest, "I'm a member of the club too."

You could almost see Luffy's soul flying out of his mouth as he lay back onto the bed. "TRA-GUY I TRUSTED YOUUUUU!!!"

You giggled and raised your arms up to reach the sky, Ace held your legs as you sat on his shoulders. "Daddy Ace is so tall!" You smiled and stretched your fingers as if they could touch the fluffy clouds above you.

"Nee, Daddy Ace, when I grow up will I be as tall as you?" You asked, resting your head on his orange cowboy hat.

Ace hummed in thought before blinking and stopping in his tracks. "Wait, since when did you start calling me 'Daddy Ace'?"

Law stopped walking too and looked over at you with a expression of disapproval.

You hummed in thought as you removed Ace's hat and placing it on your own head. "Since just now?" You responded, setting your hands on his hair and tugging on it lightly like reins. "Hyaa, horsey!" You laughed.

Normally Ace would have beaten up anyone who did something like that but, since this was you, he decided to play along instead.

With a wide grin, he held on to your legs and started running, speeding past Law and his brothers. "Later, slowpokes!" He called behind him as he ran.

"Slowpokes! Slowpokes!" You echoed him and waved bye to Law as Ace turned a corner and disappeared.

Law scowled and started to chase them down, only to be picked up by Luffy as they all started to run after the little (Name) thief. "AAAAACE! GIVE (NAME) BAAAAACK!" Luffy hollered.

You looked behind your shoulder to see your two other dads and an angry Law struggling to be freed from Luffy's hold.

"They're catching up!" You squealed in excitement, the chase was on now! You hugged Ace's head as he began to pick up speed. You exclaimed multiple apologies to the other people walking by with "Excuse me!" or "Sorry!".

Ace darted passed the crowded sidewalks and headed into a shortcut in the alley. The stench of garbage filled your lungs so you had to cover your nose with one hand and hold on to Ace with the other.

The alleyway led into a clearing, the kind of place where there were old bookshops long forgotten by the public. That's when Ace slowed down into a stop, panting heavily and sweat beading down his face.

"Hadn't... run like that in a while...." He said between pants.

You slowly slid your way down his back and glanced around curiously. There were shops here, that was what you noticed first, antiques and old clothing stores that were now boarded up and abandoned.

You walked to the glass display of one of the shops and eyed the mannequin standing there in a frilly outfit that looked like it hadn't been worn since the Victorian era.

The sound of a bell chime made you flinch and look over, where a man with blonde hair was coming out of an old pub. He was very muscular and had this sleepy look on his face.

He turned to face you, as if feeling your gaze, and raised an eyebrow at you. "What are you doing here-yoi?" He asked, his lips starting to form a frown. "This isn't a place for kids."

You gasped, running over to Ace and hiding behind him. "Marco, don't scare (Name)." Ace chuckled and placed a hand on your head. "I was the one who brought her here anyway."

The man named Marco didn't seem all too pleased with his answer. However he didn't seem angry at Ace either. It was hard to tell when the guy didn't show much facial expression...

"Daddy Ace...?" You weakly called out as you peeked from behind him.

"Hm?"

"That guy... Looks like a pineapple..." You whispered loudly.

Ace blinked at you, slowly grinning and glancing over to his friend. "Yeah, I guess he does." He laughed and walked over with you following close behind him.

"Did she just call you daddy-yoi?" Marco asked curiously.

You stared at him with interest and tilted your head. "Yoi?" You echoed before giggling and repeating the strange word. "Yoi! Yoi!"

"Is she... Making fun of me?" Marco asked, looking at you with a frown.

Ace laughed nervously and clamped your mouth shut with his hand. "She's only nine."

"Is she yours?" Marco knelt down on one knee and looked you in the eyes. "I don't remember you having a girlfriend or wife-yoi."

Ace held his other hand up in defense. "Hey, I didn't do anything. It was Luffy who adopted her and this other kid named Traffy." He sighed. "The only reason why I'm a dad was because Luffy wrote Sabo and my name as spouse!"

You pushed Ace's hand out of the way and smiled. "Hi, I'm (Name)!"

Your (E/C) eyes sparkled, making Marco smile at how easily you switched from scared to cheerful around him.

He then brought you and Ace in the pub where the rest of Ace's friends were drinking and singing some song you've never heard of before. What amazed you though was the giant man that sat there at the bar.

His white mustache curled up like a horseshoe and his laugh was so loud that it caused the ground to shake.

"Hey, Ace, who's this?" A man asked, bending down to look at you. He seemed friendly, so you smiled at him, "Hi! I'm (Name), Daddy Ace's daughter!" You declared proudly.

As the phrase left your lips, the entire pub fell silent and all the men stopped drinking to look at you with shocked expressions.

Hm, what?" You asked innocently. Marco stood beside Ace, patiently waiting for their reactions.

"Kid, do you realize the danger you're getting into by telling people that?" The white mustache guy said.

"Pops, wait, she-" Ace began to interject but was stopped by Marco. He frowned worriedly as the blonde shook his head, watching you with curious eyes as you stared back at the giant with a serious face.

"You should reconsider this, kid." He continued. Yellow eyes locked with yours as you crossed your arms and glared at him. "I don't know if you're aware of your father's work, but we have enemies that would kill someone as young as you if they had the chance, just from knowing what kind of relationship you have with-"

"So what?" You scoffed at him, cutting his sentence off and earning gasps from the entire group. The white mustache man narrowed his eyes at you as his men frantically tried to shut you up.

"I like Daddy Ace! He's nice to me!" You looked down at the floor, your eyes shadowing as you continued to speak. "Daddy Sabo, Daddy Luffy, Law, even Hancock-chan too... Everyone else hated me."

Ace frowned and pulled his hat down.

"So you don't care if you're going to be targeted by all of your father's enemies?" The friendly man from earlier asked you.

You shook your head and hurriedly wiped your eyes. "No, I don't care."

You grinned, tear streaks still visible on your cheeks. "Not even you can take Daddy Ace away from me, old geezer!"

Nope, that was it. The entire room paled as you practically stood up to one of the most feared Mafia boss in the country.

"This kid is insane." One man whispered.

"She's either brave or stupid." A man with a black beard chuckled.

Ace facepalmed. "Maybe coming here was a bad idea..."

You giggled as the white mustache man grinned down at you and ruffled your hair.

"GURARARARA! I wouldn't expect anything less from my granddaughter!"
