Summary: After a mission went fiasco, Sengoku had enough, so Garp dumped Luffy to his older brothers, who didn't even know that he actually exist. Now, Ace and Sabo were forced to babysit the seven year old and hyperactive kid, who's always acting like he's on a sugar-high. Will they handle the brat, especially how the kid could easily get into their roommate, Trafalgar Law's nerves?

The sun was warm and bright that one fine afternoon. The sea waves were calm, lulling softly a certain Navy HQ's ship. Said ship was heading back to the Headquarters after a failed mission.
An infamous Marine Hero called "Garp, the fist" was currently staring at the box of his favorite selection of doughnuts, and that's unusual for the eccentric, bat shit, insane Vice-Admiral. He lost his appetite because he's stressed and restless for almost a week now – it was all his fault by the way – and Sengoku wasn't even helping him to relieve his stress. Instead of consoling the old man, the Inspector-General was scolding him.
Well, Inspector-General Sengoku have all the rights to reprimand the Vice-Admiral anyway. It's for bringing his spawn's brat in an A-rank classified mission. Sengoku just didn't know what went through the mind of one Monkey D. Garp… on the second thought, he didn't want to know.
"How many times do I have to tell you, Garp?! It's too dangerous to bring that grandson of yours every single time we're embarking on a mission!" Sengoku probably repeated a hundred… thousand… no, it's maybe a millionth time now- Garp couldn't even count it right; he lost track after the twentieth time.
Like what the Marine Hero would always do, he ignored his old partner's nagging. Although, this time it wasn't to purposely annoy Sengoku, but to worry for his precious grandson's safety.
Apparently, a notorious underground organization that specialized in manufacturing illegal weapons for warfare that Sengoku and Garp – along with some of the best officers in Navy – tried to infiltrate recently had found out about his grandson, Luffy's identity- the culprit for the mass destruction of the warehouse, where lots of illegal weapons were stored… as well as the legendary powerful weapon.
Garp was a-hundred percent sure that if the organization caught Luffy in their line of sight, they will kill him. Well, he would like to say that it's not his fault his seven years old grandson decided to have some fun, but Sengoku and the higher-ups said otherwise though; they insisted that Garp was responsible for the fiasco in their recent mission.
"And now, look! He's the cause of our, yet another failed mission, and who would have thought that your spawn's brat has the ability to do that! Especially to destroy the legendary one!" Sengoku hysterically ranted.
He tried to calm down by massaging his temples, counting one-to-ten and stroking his braided-beard as well, which was slowly turning grey because of stress from a certain eccentric and crazy old man. Obviously, the Inspector-General was more stressed than Monkey D. Garp because he had to deal with several things like: reporting to Commander-in-Chief Kong about the failed mission to confiscate the illegal weapons and to retrieve the legendary weapon (now, a useless scrap of burnt metals), explaining to the Old Farts in the World Government why the considered "best officers in the Navy" failed in their mission again, and pacifying his anger towards his crazy partner, who thought that bringing his grandson in the mission was a good idea.
"Vice-Admiral Garp, is this yours?" Sakazuki, one of the Rear-Admiral had gruffly said while holding the Marine Hero's grandson on the back of said brat's shirt like a stray dog.
Rear-Admiral Sakazuki found Monkey D. Luffy wandering in the Navy Ship, and the brat managed to almost fell overboard. Luckily for the kid, the Rear-admiral spotted him before he would drown to death.
"Yo!" The seven year old child greeted as he raised his hands while widely grinning.
The child's antics only served another nerves to pop at the Inspector-General's forehead. He's almost a photocopy of his grandfather!
Suddenly, a sleeping Rear-Admiral Kuzan, who's taking a nap on the uncomfortable reclining chair at the corner of the Inspector-General's office, happened to hear the conversation earlier. He lazily peeked out an eye from his sleeping mask before speaking what's in his mind,
"Garp-san, are you… sure that there are no adults available around to look over your grandson?"
Garp's shoulder slumped as he heavily sighed. He knew very well that it's dangerous to bring Luffy to his missions, but there's nobody else he knew to look after Luffy.
'Well, there's Makino, but she's in a Honeymoon Vacation after she married that red-hair punk, so she can't look after Luffy like the usual.' Garp had thought at the same time, unconsciously saying it out loud.
"What about Ace and Sabo- your other grandsons?" Sengoku suggested, frowning at Garp, "They are Luffy's older brothers, right?"
Garp looked at Sengoku before realization had hit him. Kuzan and Sakazuki recognized the look on the Vice-Admiral's face, both Rear-Admirals were giving the Marine Hero an "are-you-ridiculous" look.
"Oh right! Those ungrateful brats," Garp loudly said as he picked his nose while laughing as hard as he can… as if his impulsive decisions didn't cause the Navy a lot of failed missions, "How can I forget them?"
Another round of cackle came from the oblivious Marine Hero. His laughter had echoed inside the Inspector-General's office. Oblivious to the fact that Sengoku was glaring daggers at the still cackling bat shit and insane old man.
"IDIOT!" Yelled by an angry Sengoku, who's ready to jump to kill Garp, but was restrained by both Sakazuki and Kuzan.
The Rear-Admirals were surprised that all of a sudden, they realized that their non-existent teamwork improved a little bit as they tried to stop the Inspector-General for doing something he will regret in the future- by killing the Vice-Admiral.
"Now, who wants some doughnuts?"
Outside the office of the Inspector-General, Rear-Admiral Borsalino and Lieutenant Officer Momonga have passed by…
"I thought that the legendary weapon was supposed to cause a mass destruction…" Lieutenant Officer Momonga stated.
"Indeed, but the weapon itself was apparently massed destruct beyond repair along with the others." Rear-Admiral Borsalino drawled beside the Lieutenant Officer.

Ace and Sabo suddenly sneezed at the same time. Both suspiciously looked around them because they're sure that someone was talking about them.
How many times did they sneezed for an entire day? They both glanced at each other before shrugging it off, going back to their business: Ace was reading something at the glittered and scented paper– a letter he received earlier as he leaned at the locker beside his own and Sabo was arranging his books, placing them properly inside his already full locker.
"Are you going home after your last class, Ace?" Sabo asked his brother while trying his best to squeeze another book about Laws and Constitution between his already thick books inside his locker.
Unfortunately for Sabo, he couldn't arrange his locker to his liking. It's full of chocolates and confession letters from the girls, who admires him in the University. Today was Valentines' Day and for handsome and hot guys like Ace and Sabo, they sure get a lot these things.
They're quite popular after all.
"Yeah," Ace replied as he tossed the letter at the nearest trashcan after perusing it.
Lucky for him, it was the last one that day. Ace turned around to look at his brother, who's grimacing at the letters and chocolates inside his locker.
He sighed before adding to his blond brother, "…cause the geezer said he's coming."
"But it's not the third week of the month yet!" Sabo quickly protested while frowning, taking out the chocolates and letters inside his locker.
It's apparent to Ace that Sabo wasn't excited to see their grandfather again after what happened two months ago.
Said grandfather always keep a habit of visiting his precious and beloved grandsons every third week of the month. He said that it's to (bother) spend some quality time with his grandchildren, dropping their monthly allowances as well. It was a common knowledge among his family and comrades that Monkey D. Garp doesn't trust the banks.
"I know, but he just called me a while ago." Ace informed Sabo as he closed the door to his own locker, gripping the said single strap of his green-leopard rucksack afterwards.
Sabo raised a single yellow brow at Ace and then, he stopped what he was doing at the same time, carelessly dropping some of his stuff on the marble floor of their university as he attempted to catch them.
"Why so sudden?"
"Dunno," Ace shrugged as he yawned, "…geezer just said that it's important."
Sabo suddenly hummed, "I wonder what he is talking about this time... did he told you?"
"He didn't mention it over the phone, so you better go home early after your class too if you want to know," Ace lazily told his brother as he leaned over his closed locker and smirked, "I don't want to suffer alone with gramps' craziness."
"What?!" Sabo groaned.
"What is your 'what'? Don't tell me you're going to abandon me and deal with gramps?"
"Ace! I can't go home early today."
"And why is that?" Ace suspiciously asked as he raised his eyebrow.
"I have plans today and I've been waiting for this day to spend with Koala. She will be very busy next month for her OJT, and I'll be busy too since Finals are coming next month! We're already busy this past few days that it's rare for us to spend some time together," Sabo seriously replied to Ace as his brother's facial expression grew angry each passing seconds and then, Sabo remembered their roommate, "And notify Law already that gramps is coming to town! You know how much he told us that he hates gramps after what happened the last time."
"Oh… yeah! That's another problem too!" Ace exclaimed in frustration and quickly sent a message to Law.
Sabo sighed as he remembered what happened last time. It's going to be a very long week for them, especially their roommate, who actually announced that he loathed their grandfather after what happened when the crazy old man visited them.
Ace is about to send the message to their roommate when Law's name appeared on Ace's smartphone screen.
"Law! Hey-" Ace answered, he was cut off by Law's annoyed tone.
"Your grandfather is here."
Ace gulped with a troubled expression and looked at Sabo. Based on Ace's reaction, Sabo already knew that it's too late. The D brothers are sure that Law will kill them; sadistically and brutally, and he's going to enjoy it.
