Ace is riding his Strikers through the sea until he saw Going Merry and quickly recognized it as Luffy's ship. He decides that he will go to the ship to visit them. As soon as he getting near to the ship, he smells such a fantastic smell that he sure that their cook is making lunch right now. Without hesitation, he climbs Merry up to meet Luffy and his crew. As soon as he reaches onto the deck, his cute little brother is surprised to see him and quickly welcomes him to the ship.

"Aceeee! Let's eat lunch together!" the boy chirps as he run towards his brother and gives him a big hug. Ace agrees to have lunch with them and Luffy is overjoyed. Ace laughs while rubbing Luffy's soft messy hair. Luffy squeals happily. "Shishishishi...just a few months ago Sanji raise me like his own son and he always care ease my hair like that!" Ace doesn't understand what Luffy is saying and continue rubbing Luffy's hair while the younger boy continue hugging him until he realizes that Luffy is not releasing him go at all.

"Hm? What's wrong Luffy?" he asks, confused. The boy chuckles, and suddenly let out a pink blush with such a happy expression on his face. Ace is shocked to see his little brother's sudden expression, like a lovesick high school girl.

"Ace, will you stay a night?" the boy asks.

"Well, I can if that's you want..." but as soon as he agreed, Luffy tightens his hug and cheers like a girl who just got confessed by the guy she likes. Ace is really confused by his little brother's weird behavior. But he admits Luffy looks cute, though.

"Sanji! Ace comes!" Luffy calls toward the galley where Sanji is working.

Ace grits his teeth. He definitely looks forward to see the blonde cook again. He has been attracted to Sanji from the first time they met since he's the most matured among Strawhat crew. And his cooking is really delicious. The way he treats Luffy is almost freaking motherly, and that makes him want to know Sanji more. However...

"Oh, the lunch is ready! Come to the galley, oni-san too!" Sanji shows himself from the galley. Ace is shocked to see the condition that Sanji is in. Sanji right now, is entering nine months and the baby will born anytime. Though he supposed to rest on the bed, he insists to cook for the crew as long he affords to do it.

"#$%&8i&84fju56~ #4!"

Ace's scream can be heard even from nearby island which is supposed to be 10 meters from their ship.

Zoro supports Sanji from the back since his belly has been too heavy for Sanji to even stand. Sometimes the baby kicks and Sanji happily care eases his belly. He doesn't get any grumpy anymore and already accepted the fact that he's pregnant with Zoro's child. No matter how weird the situation is, that baby is still their child and it's their responsibilities to raise it with love until it can make its own mind. Well, for now, let's take this chance to be a happy family.

Ace feels freaking awkward right now. Poor Ace, his first crush is already being taken. Not that Sanji even know that he thinks about Sanji that way. But he kinda happy for him. Even Sanji is not his, he doesn't angry, sad or anything qualifies as heartbroken. Yes, no. However, Ace never realizes that there's somebody else who got crush on him. For more than 10 years, he never realizes. He is an idiot and that's why. He figures that he needs to say something. "So...are you okay?" he asks, fail to remove his sight to the swollen belly of Sanji.

"Yes, I'm fine, thank you. I'm entering nine months now and I feel like this mini marimo is ready to get out anytime," Sanji smiles while rubbing his belly while playing with the still unborn infant. "By the way, Zoro is the father."

"Oh..." Ace looks at Zoro. Think it back, they look very close to each other. Who thought that they end up being a pair of spouses in this ship? However, they looks match to each other. He also always thought that Zoro is kinda close to his little brother. Well, he is Luffy's first mate though. But to think that both of the crews which he had eyes on suddenly become a parent, it's kinda shocking for Ace. He looks at Luffy. Luffy looks happy that they will get a new nakama. But...do they seriously want to raise a baby in the middle of Grand Line? Well, not like they can drop the child anywhere. So, he decides that no matter what decision that the couple made, he will always support them since he is confidence that the whole crew will take care of the baby.

Ace is resting while enjoying the soft breeze from sea winds at the deck. He's trying to sort all the things he encountered today. His first crush...maybe not, his second crush is going to be a mother. Maybe his feeling aren't even strong at all, since he didn't even feel sad. But then, he starts thinking about future. Sanji is pregnant. Then the whole crew need to protect the baby. Luffy? How about him? Does he care? But he looks happy too. Suddenly, Ace starts to see that something is wrong. Huh?

Luffy is extra clingy today.

Ace tilts his head. Something is definitely wrong here. He doesn't know why, but Luffy is definitely different today. He might planning something. But, what?

Ace walks around the deck to search for Luffy and end up at the galley. He enters the galley and found the heavily pregnant cook at the kitchen. Sanji realizes that Ace is here and slowly walks to him.

"Wait, you don't have to walk! I just want to find Luffy after all..." Ace panically said as he rushes toward the cook. He drags the nearest chair he can find and let Sanji sit on it. "Um...You see..."

Ace sit on the chair next to him. "Today Luffy is kind of weird."

Sanji frown. His brain tries to figure out what is not weird about his captain. Suddenly his baby kicks and Sanji care eases his belly lovingly. Ace feels awkward to see him. In facts, it's his first time seeing a pregnant person after all.

"Luffy said you raised him like your own child," Ace starts his conversation but hearing that shocking Sanji and he starts to cough.

"Ah...that..." Sanji smiles unwillingly.

And so, he starts telling the whole story about how Luffy accidentally ate Apple of Youth and becomes a newborn and how he never realizes that he's pregnant that time to Ace. Ace is shocked to hear Sanji's story. He never thought that he missed the event where Luffy is babyfied and he was not there to take care of him. He met Luffy at 10 where Luffy was 7 that time so he never know how baby Luffy look. He regrets that he never visit Luffy when the incident happened. He cries hard after Sanji finished his story and sweats to see Ace's behavior. Ace can't believe that he missed the chance to hold his small and delicate baby brother and he regrets it very much. Zoro who happens to enter the galley for some booze is shocked to see Ace crying like a kid while Sanji is trying to comfort him.

"What happen?" Zoro asks his spouse while pointing to Luffy's brother.

"Ah...he cries that he missed his chance to carry baby Luffy on his arms," Sanji sweats while care easing his oversized belly. It seems like the baby is laughing to Ace too. Zoro sweats too.

Meanwhile, at infirmary Luffy visits Chopper at his post.

"What's wrong Luffy?" Chopper asks.

Luffy suddenly smiles and Chopper is shocked. His smile must means something.

"Chopper..."

"Do you have any 'making babies' medicine?"

Chopper is shocked, and mostly frightened. What for?! Luffy, of all people?!

"I have someone I like...and tonight I'll definitely make him realizes my feeling!"

Chopper faint. Luffy is shocked and immediately rushes to the reindeer. Foams already forming out on his mouth since he can't accept that his naive captain will ask for something...adult. Well, he is no adult either, that's why he's scared. It took about 2 years for him to understand the adultery committed by Zoro and Sanji which leaded to Sanji's pregnancy.

"No choice, huh?" Luffy put Chopper on infirmary bed and walks towards his bookshelves. He picks a book and start reading them one by one though usually he never interests on book. After flipping and tossing a few books, he finally found what he needs. He searches for the material needed from infirmary and mixing them like it was told in the book. He is an idiot but today he thinks he is a genius. "Hehehe...Ace...With this, you'll like me, and me alone..." His voice and laughter echoes throughout the infirmary. Luckily, no one is close enough to hear it.

"So, what we're going to name it?" the young father-to-be asks his spouse while rubbing his spouse's belly. Sanji smiles. His brain is thinking too.

"Nahh, let's think together with our crew later," he gently answer. Both of them laugh until they heard a voice approaching him.

"Whoa! Such lovey dovey! When will both of you get married?"

"Nami-swannn!" the cook chirps as Nami walks closer to them. Zoro blushes as their private moment was interrupted by the navigator. "What do you want?" he asks and Nami sighs.

"Well...I found Chopper fainted just now. He looks really shocked," Nami explains and let out a big sigh.

"What? Chopper fainted?!" Both of the couple are shocked and quickly rushes to the infirmary. There they found Chopper on the bed. Zoro found that Chopper's table is messy with books and the medicine materials that Zoro doesn't even know what they are while Sanji is worried about Chopper. Both Zoro and Sanji are speechless and look at each other until they heard a small whine coming from the little reindeer. They quickly rushes to Chopper. "Chopper! What's wrong?! Are you okay?!"

"Hm..." Chopper opens his eyes until he starts to remember what is happening before he fainted. "Luffy has become crazy!" Then he saw his table's condition. "Ahhh! He made the medicine without my permission! Damn you Luffy!"

Zoro frowns. So does Sanji. "Luffy? He made medicine? Our Luffy is?!" Yeah, for them it is such a joke. Luffy never take interests in book so he never read. Medical field needs a looooot of readings so there's no way Luffy is willing to study complicated medical stuff. So, for someone like Luffy...let alone commoners or outsiders like them...Should even never touch medic stuff that they didn't even know! It's dangerous damn it! And why the hell Luffy is making medicine after all?! Isn't it is weird?! And mostly...what did he even made?!

"LUFFFYYYY! COME BACK HERE!"

Ace awakes from his afternoon nap, probably caused by his narcolapsy. He heard somebody calling for Luffy. But before he can check where the voice come, he bumps into his cute baby brother. "Acee!" The boy calls for him energetically and quickly jumps on him. Ace is surprised by the attack and quickly catches Luffy. He really understand nothing about Luffy's weird behavior today.

"Luffy, what's wrong with you today?" Ace sighs while the boy is hugging him affectionately like they have not seen each other for 10 years. Luffy's lip suddenly looks shiny as he looks direct to his brother with sparkling eyes.

"Ace, I..."

"LUFFY!"

"Tsk!" Before he managed to say something, those angry people had already call for him. But his plan is yet to be revealed so without choice, he needs to flee..

"Ace! I'll tell you tonight, okay!" Luffy shouts and quickly run away. Ace is stunned. He understand shit about the situation. What is Luffy's plan anyway? What is his real intention? Guess he needs to wait until tonight after all...

Ace saw a bunch of crew passing him while chasing their naughty captain. Not long after they gone, he saw Sanji who walks slowly, not bothering to follow them due to his condition.

"Um...What did Luffy do?" he asks awkwardly as his eyes watch the big belly. Sanji sighs.

"I don't know what he intent to do this time but...to think that he created a medicine without supervision...this is first time..." Hearing that Ace chocked himself. Luffy? Of all people? Making medicine?! Wait...As soon as he realized what they just got into he start feeling kenopsia.

"That's dangerous!" he hysterically screams.

Sanji sighs. He can't agree more. If he's not heavily pregnant and about to pop out anytime he's already joining them catching Luffy. He touches his belly. To be honest today he feels uncomfortable but it's nothing serious. But if he said that everyone will go into panic and the tension might forces this little one born premature so he better keep it quiet. But now...eh?

He starts to sweat and pants heavily. Ace who intent to go after Luffy stopped as he saw the cook suddenly fall to the floor and stunned. Quickly he rushes to the trembling cook. "Oh no..."

"It's bad...OI! SANJI IS IN LABOR!" he screams while holding Sanji who's trying his best to hold his pain. It turns into uproar when the whole crew heard Ace's scream and quickly rush toward them and Luffy's matter forgotten. The first one who reach at the scene is non other than Zoro. Quickly he grabs his waifu and quickly rush to the infirmary. He found that Sanji had endured the pain too long that he had lost his conciousness as soon as he lie down onto the bed. Later, Chopper reach to the infirmary with some herbs on his hands but as soon as he saw Sanji, he starts to get panic.

"Gyaaa! Sanji! Someone call the doctor!" the small doctor screams in fear.

"It's you!" shouts Zoro.

A few seconds later Sanji heard someone calling his name and an enormous of pain attacking him as soon as he awake. "Ahhh! What?!"

"Oh, you've waked up? Just calm down now and hear me." Chopper intents to calm Sanji down but finally he himself can't control his nervous. "THE BABY IS COMING!"

"GYAAAA!" Good, now even everyone is panicking.

"Calm down...Chopper...you...are doctor...are you?" Only Sanji knows how much panicking isn't really benefitable at this moment. He knows for sure that this is Chopper's first delivery and he himself is having his first baby so they need to calm down a bit. Thankfully, Chopper backs to his sense after hearing Sanji's painful voice and quickly reaches out his tools.

"So...sorry Sanji. It is painful? Of course it is..." Chopper is trembling. Oh god, what should he do, what should he do?! However, after taking a deep breath, he finally regains his sense. "Okay guys, we need to work together for the sake of Sanji and baby!" His action turns to be effective since everyone seems to calm down and agree with him and cheer, "Oh!" in synchronize.

"Okay Sanji I know it's weird but try to push. Just do it slowly. Zoro is here to hold your hands so you don't have to worry. Okay?" Chopper coax the blonde cheerfully in order to ease the labor cook's mind. However, as much strong he can be, it still hurt!

"Hngkk..."Sanji tries to hold the scream. If he have energy to scream, he better spending it to get the baby out! The baby needs him and he must ensure its survival! He grips into his lover's hand and try as hardest as possible to push the baby out. Just like Chopper said, it's really weird for a guy to push the baby out from his womb. Aren't they supposed to get it out through cesarean? But since Chopper said he can, then he'll try.

"Come on, Sanji! You can do it!" Nami coax, encouraging the cook. "Oh my God, why am I the one who get the duty of delivering it?!" Though she herself is still in panic, plus scared with what's going to come out in front of her very eyes until for sudden… "Hiekkk! It's coming!" Nami screams hysterically.

Robin can only laughs to see the young girl's antic and turns to the cook in pain. "Come on Cook-san, just a little more!" she encourages. Sanji is shocked to hear that and starts to harden his effort to push his child out. "Just…a little…bit…more!"

"Hnghkkkkk!" Sanji screams in agony.

Meanwhile, Ussop and Ace are waiting outside the infirmary, mainly to detain Luffy from ruining everything, especially when he is with a dangerous unknown medicine.

The raven hair teen frowns. "Hm…is the baby born yet?" he whines. He is already can't wait to play with it! Why a childbirth is always this long?

"Luffy, a childbirth is not easy. My mom died giving birth to me, you know?" Ace doesn't want to scare Luffy but he needs Luffy to know that a childbirth is a matter of life and death. However, Luffy starts to get blue and screams, "EH?! SANJI IS GOING TO DIE?!"

"No, Luffy! He is strong so he will definitely survive! My mom was already weak from Haki overuse, so…Ah, that's what Grampa said though." However Luffy starts to sob, shocking the older pirate.

"HUWEE! SANJI! PLEASE SURVIVE!" he cries in agony. Ace sighs. No matter what, Luffy is still an innocent teenager after all. There's no way he will know about how harsh human nature is.

A few hours later, it is raining cat and dog. Everyone is already frantic. They are worried about Sanji and baby's safety.

"UWEHHHHHHHHHH!"

Everyone is shocked. A loud cry rings like a thunder. Ace, Luffy and Ussop look to each other, and slowly form a smile and grin.

"YATTA!"

Quickly they barge into the infirmary to see Sanji and baby.

"Sanji!" Luffy is the first one who enters the infirmary to see their new nakama.

"Shh!" Sanji said, a bundle on his arms. They can see a tiny green spots from far. "Meet Midori. He is a guy though." Everyone is excited. Luffy is overexcited. Zoro is definitely extremely overjoyed.

"Wow, he's cute! Midori-chan! This is Auntie Nami!" Nami coos the baby. The baby had just being fed and feel very sleepy right now.

Sorry, I think I'll make another chapter about AceLu later. I have wrote this chapter loooong ago but can't bring myself to finish it. But for now you can try reading Roronoa Household.
