Authors note: I want to thank you, the reader, for deciding to read this. I haven't contributed anything to in about 3 years so bear with my change in writing if you decide to read my older stories or have read them, in the near future I plan on re-writing them but as for now I am currently writing this along with short stories of my own. Keep in mind that this is set in an alternate universe. I am not new to the series but I haven't captured some characters personalities well because I have not seen much interaction with them (mainly Ace and Whitebeard) so there could be possible out of character scenes. I just want to apologize in advance if this story in any way harms or offends someone. Rated M for later chapters. Thanks again!

Disclaimer: I do not own One Piece, I do not own any of the characters depicted in this story besides the OC, which is obviously mine, props to Eiichirō Oda for creating such a great cast and story.

Warnings: If you aren't up-to-date with the manga, which is currently chapter 584 and anime episode 451 then I would advise you not to read this due to possible spoilers, unless you like them then continue forward.

Pairings: This is subject to change but so far I know that I am including AcexOC, SanjixZoro and possibly RobinxFranky.

Summary: What happens to Ace when Whitebeards daughter comes to live with them?

The Trip

The day was just like it had been for the past couple months, clear, sunny day with a light breeze passing through. Ace stood outside on the patio gazing up into the big blue area that seemed to expand through eternity itself. His ebony hair flowed smoothly as it caught the wind. He smiled to himself, took in a deep breath and admired the crisp air.

"Seems like days as beautiful as these will never end." He thought peacefully before he was interrupted by the opening and slamming of the front door. Ace did not care to glance back to see what the commotion was for he knew exactly what it was. Her. It was that girl, the girl who had joined his small happy home with his adopted father, Whitebeard, about seven months ago. "Marin" he smugly mumbled. Ace had not liked her since their meeting, which he vividly recalled every time he looked at her.

It was the regular time for Ace to get home from school 2:45pm sharp. He got out of his forest green Mustang and walked up to the stairs to the front door while whistling and twirling his car keys around his middle finger. He places his hand on the knob and gave it a spin then walking into the living room and seeing a young girl sitting on the couch. "Yo." Ace said while holding up a peace sign. "Who is this? Didn't know you liked 'em so young pops." Ace plopped down on the love seat that sat a solid eight feet away. The girl wrinkled her nose and narrowed her eyes. "Ugh! You damn prick!" she paused briefly. "Your pops is my Pops!" she then crossed her leg over the other and folded her arms, pouting. Ace cocked his head to the left and raised an eyebrow. Whitebeard then came from the second floor and smiled. "Ah, son! You're home, and I see you met my Mari!" he smiled and sat down next to the girl.

Ace then thoroughly examined the girl. She appeared to stand about a foot shorter than him, same age too. Her hair…a light creamy caramel with eyes that shown amethyst, her lips were the color of peach and skin as pale as the snow itself. Ace then moved to her clothes. Her neck was hidden by a turquoise scarf, body draped with a burgundy sundress, thighs covered with fish net stockings and her feet wore black suede boots. "So who is this, pops?" Ace asked before blinking and giving the girl another gawk. "This is my lovely daughter, Gu ra ra ra ra!" Ace gulped…and gulped hard. "Eh?" he asked giving a nervous laugh afterward. Whitebeard placed his hands on both of Aces shoulders. "Son, please…watch over my daughter Mari!" Ace knew he couldn't refuse Whitebeard and he also knew he didn't want to baby sit another person, Luffy was enough, but Ace slowly shook his head in agreement.

"S-sure" he stuttered then glared over at Marin who was charging straight for him. She circled around Ace. It was her who was now giving the thorough exam. Marin looked Ace from head to toe. "I have to further this investigation." She thought aloud then began to touch and grab on him, starting from the forearms and ending with the ass. Ace began to get flustered. "W-w-what is wrong with you girl! Marin then turned to her father, smiled and gave him a thumb up. "Daddy….he passes! He can be my guard!" Whitebeard smiled and brought the three of them together in a huge bear hug. "We are going to be a happy family, just the three of us!" he gave his Gu ra ra laugh afterward and was so ecstatic anyone could tell.

"Yeah…some big…happy family this has been." Ace spoke his thought aloud. "This is just a nightmare." He corrected himself. "Well the past seven months anyway." Marin then walked toward Ace and put her hands on her hips, taking in the beauty of the day like he had just moments before. "Great day, huh?" Marin spoke happily but there lingered some sadness behind the joy. Ace looked over, acknowledging that he heard the hidden feeling. "Yeah, what's wrong?" "Dad is going on a trip" Marin wrinkled her nose and let out a sigh. "So? He always does, this is nothing new."

"Yeah but…this is going to be for two weeks. Daddy is gonna be gone for TWO WEEKS!" she exclaimed. Upon hearing the news Aces' eyes nearly bulged out his head. "What!" he asked loudly, hoping that what Marin had said was just some sick joke. "Yeah, Dad leaves in a couple minutes actually." She sighed again and then sat on one of the patio chairs. She sat crossed one leg over the other and folded her arms. Ace could tell that Marin was clearly upset that Whitebeard was going to be gone for two weeks but he held no sympathy for her and just rolled his eyes. Ace was used to Marin being around and her crazy antics but he was not used to being her personal baby sitter even though he had been doing the job for a solid seven months which was now going onto eight. "I" cracked Marin's voice. "I know you don't care too much for me but…" she was interrupted by Ace. "Yeah, sure as hell don't." Marin frowned and spat out a cruel "Fine never mind then you jerk!" Ace replied with silence.

The silence was broken when Whitebeard emerged from the front door with some luggage. "Well my little Mari, I'll be seeing you and Ace in two weeks." Marin did not acknowledge her father. She simply ignored him because of how frustrated she was with both his leaving and Ace. Whitebeard gave a pouty face. "Now Mari, don't worry a hair on your precious head. Daddy will be safe and sound and back before you know it. Besides you have Ace to watch over you!" he smiled and patted her head, hoping to give her some assurance. Marin felt the warmth of her father's intentions and gave a small smile, giving him some assurance too. Whitebeard turned to Ace, now giving him the 'take care of her' speech. "Now son, I trust that you'll let no harm come to Mari and that you two will be alive and well once I return." Ace nodded, not speaking a word. Once Ace gave the nod Whitebeard felt he could leave so he headed to his truck, fired it up and took a drive down the road to the port.

Marin waved good bye as he drove off knowing he was too far gone to even see. Ace stared at Marin. It disgusted him at how she acted like a five year old when she was clearly twenty years old. Marin couldn't stand to be outside anymore since the breeze had died down so she got up and sifted past Ace; Marin glared at him the whole way from the chair to the door. He cringed at the stare, making a fist from the bottled frustration. He followed in behind her, closing the door behind him and proceeded to lie on the couch. Ace was already sick of the day so he lay on the couch in hopes for some salvation from the deep sleep he was about to undergo. "What a long two weeks this will be." He thought before entering his slumber.

Hi there, I hope you all enjoyed this first chapter so far. I suppose I have a unique way of writing and I hope you all will find it to be entertaining. This story is partially edited. Random: I think that I am the best critic when it comes to my work, maybe more feel the same way I do? I dunno. Nevertheless though I hope you all will give some positive feedback through reviews and stay tuned. Oh, another note: I hope I didn't get too OoC for Ace and Whitebeard. Hm…I guess I did with Whitebeard but that's only because I feel like if he had a daughter he'd want to be a very doting and proud father for her. I mean in the recent manga chapters it was revealed that he had always wanted a family and all he has is sons so I figured I'd make a daughter. I also wanted Ace to have a lady friend, I feel like he should because he's one of those bad ass guys who deserves a lady. Of course though they don't get along so great but who knows how things will turn out, I don't do happy ending when I write so you never know. Thanks again for tuning in and I should have something more entertaining like an Omake Theater after the end of the new few chapters instead of a long ass rant from me. Until then reader!
