Title: Brotherhood

Rated: K+

Summary: In which Giotto and Tsuna were brothers—and the former had a huge brother-complex toward the latter while the latter was completely not aware of it.

Warn: AU, big brother!Giotto, little!Tsuna, ooc, dialog-heavy, absurd, weird, not beta'd.

Disc: I don't own KHR.

A/N: A wild muse-for-update has appeared! /no

Uh, hello again, apparently my muse for this thing just had to actually start working again after I finally said the joys of writing this has been more or less gone (it still applies tho), weird. Anyway, more "plot" related dump and also small tidbits of this AU that I actually like (and still crack, 'cuz of course), and, uh, I actually also have a basic timeline of events for this thing I guess…? If anyone's wondering...? Also spoilers for future (remaining) chapters…?

Ch 9 - ch 7 - ch 5 - ch 1 - ch 8 - ch 6 - ch 2 - ch 3 - ch 4

So yeah, heads up, it'll prolly end in chapter 9 (hint, it's abt Giotto's merry band of misfits and G questioning his sanity, as always), anyways, happy reading!

"This is boooriiing."

"Well, it's your fault we got into this mess in the first place, stupid." Akage "G" Gokudera retorted whilst Ieyasu "Giotto" Sawada pouted with his head side-planted on the small coffee table and Ugetsu Asari stacking a couple of cards into a fully-bloomed flower (don't ask) beside him.

The three were currently cooped in the blond-headed teen's room, trying to finish a project they had been given by their teachers as a form of punishment for… certain events earlier today at school.

(It had involved an accidental victim of a stray-prank, turned into small prank exchanges, then turned into an all-out prank war for the turfs of four major prank guilds in the school grounds that lasted for a week before it got settled between the last two remaining guilds, with the blond-haired teen's reigning as the champion. It was awesome and was definitely not a pretty sight for anyone looking from the outside.)

Sighing, Giotto flicked the nearby erasers toward G (because one, it was always fun messing with his red-haired friend, and two, he had learned the hard way the last time he tried disturbing Getsu's state of perpetual zen, Giotto shuddered) as the teen continuously ignored his friend's boredom while redoing the schematics of their project again for the umpteeth time. It was for the upcoming school cultural festival they had been tasked to be in charge as part of their punishment.

Since the blond-haired teen's group was the one who had won the prank war, it basically fell into their hands as the one to take most of the blame for the week-long chaos. So, as the ever loyal friend he was (as much as he wanted to strangle his best friend sometimes, most of the time), G took it upon himself as the self-appointed logistics manager and secretary while Giotto became the "leader" of the committee and Ugetsu as the treasury.

(In other related topics, Nanakiri "Knuckle" Sasagawa was placed in decoration, Heiko "Alaude" Hibari was appointed in security (big shocker), Raiji "Lampow" Densagi immediately called dibs on food stalls, while Daemon Spade begrudgingly took part as the overall master of ceremony. The wider their range of sight from each other the better.)

If anyone was going to make this work, it was him and he could always make Giotto do a rousing speech whenever the other members and students were being stubborn, and lazy, and needed a little pinch of charisma-induced goals.

(Probably one of the few good things about Giotto was his natural charm and charisma—G certainly would have had maimed the guy for just being an awful, awful, awful friend since day one if he weren't, to be honest.

No, actually, the sentiment still lingered and actually got stronger by day. So never mind.)

Seeing his friend wasn't going to respond to any of his kick-erasers, Giotto harrumphed, slowly got up from the floor and lazily propped his chin on the windowsill of his room. Looking downward with half-lidded eyes (he was suuuupeeer booooreeed alriiiiiight), his ears quirked when he heard the familiar footsteps of his little brother just outside of his room.

"Onii~chan~" Tsunayoshi "Tsuna" Sawada cutely asked with a small head tilt and a sing-a-song voice from behind the now-opened door, "Kaa-chan wanna know if Oniichan and friends want cake later~"

"TSUNA COME GIVE ONIICHAN A HUG—GACK!"

As he snapped his head to the door, the blond-haired teen instantly stood up with renewed vigor and was about to hug-tackled the small boy when G had suddenly grabbed him by the collar, quickly choking him in the process

Blinking, Tsuna looked up to the growling red-haired teen, "Oniichan okay?"

"Oh yes, he is," it was Ugetsu who answered the little child, his mouth curved into a smile, but somehow his eyes looked like weren't smiling as well (from the corner of G's red eyes, he could see the scattered cards Giotto had knocked out earlier, the shorter teen was doomed). "But I think Tsunayoshi-kun should play outside today—or else Oniichan can't finish his homework, okay?"

Tsuna's eyebrows slightly knotted as his mouth turned into a determined pout, a sign he was thinking hard about the sudden task at hand, before gasping in shock and nodded, "Kaa-chan say homework not finished is bad! Tsu-kun gonna play in the park now, Oniichan!" Then with a small wave to the three older teens (two somewhat pissed friends and one half-conscious older brother), Tsuna quickly skipped downstairs and went outside with a small orange hoodie on over his body.

After Giotto had regained two-thirds of his consciousness, he immediately ran back toward his windowsill, yelling.

"NO TSUNA NO—OOMPH!"

"Can't you just stay still! For one! MINUTE!" G huffed, wrangling the blond-haired teen from jumping over through the second floor window with his raven-haired friend and help him finish the dang cultural festival plans dammit! He still wanted to live from the Demon Math Teacher from Hell until he graduated as the school's valedictorian dangit!

"YOU'LL NEVER TAKE ME ALIVE—"

"Oh for the love of," in an instant, Ugetsu had chopped the back of Giotto's head as the shorter teen was half-hanging outside on the windowsill after being rendered fully unconscious.

Giving the teen beside him a dirty look, G frowned, "why didn't you do that in the first place?!" They could have saved a bunch of headaches from dealing with Giotto's shenanigans earlier!

The taller teen merely blinked then gasped accusingly at him, a hand dramatically pressed over his chest, "G! However could you imply that to me—you know I only use violence as my very last resort!"

His friends were sadistic lunatics, the red-haired teen swore.

As he silently muttered profanities under his palm-covered face, G dragged the limp blond-haired teen over his shoulder then dumped him onto his bed unceremoniously, not even caring if he would ever get a concussion from that.

It went peacefully and productively quiet for the next three hours (G still pondering over the plans and Ugetsu continuing to build his blooming-flower card sculpture like before), until Giotto began to stir in his sleep and slowly woke up, gingerly rubbing the aching back of his neck as he looked around.

"Wha happen?"

"Getsu almost snapped your neck in half since you knocked over his cards," G not-so-helpfully replied, his eyes still roaming around the large paper sheet in front of him, "anyway, we still need to finish this by the end of the month, or else Reborn-sensei's gonna have our heads mounted on his teaching lounges."

"O yea…" Giotto muttered, his words still drawled since half of his mind were still elsewhere. He had mindlessly sat beside G to help him with the arrangement of the concession booths for a few minutes until his eyes widened as if being struck by lightning (which he actually had, thrice, with G, Knuckle, and Lampow, it was a very weird day that day) and was about to instantly bolt out of his room to search for his precious little brother if it weren't for Ugetsu's pointed stare and the red-haired teen's unnerving choke-hold on his collar shirt.

"Think about stepping out of this room again, and I'll tell your Mom about the 'Garden Incident' last year." G hissed as Giotto squawked.

"You have no evidence against me!" He made sure to dispose anything that could trace the cause of that incident back to him immediately on the D-Day! There was no way G had it since he was preoccupied with his little sister!

The taller teen merely snorted whilst throwing a look toward the tallest teen of the trio, his mouth curved into a slight smile and a sinister glint present in his eyes.

"Want to bet on that, Giotto?"

(Understandably, among their rag tag of troublemakers, Ugetsu was one of the least destructive, along with Knuckle on a good day, but when someone messed with his slice of tranquility, even if it was for something petty, he would definitely returned it fourfold times over and would still hold a grudge after that.

His pettiness probably rivaled those of Alaude and Daemon—and people wondered why G was the probably the sanest guy in their little group.)

The dangling teen immediately did a double-take and shook his head, before his eyes brightened up again, as if having another "brilliant" idea in times of crises, and turned his head toward his still-opened window, shouting.

"I summon thee!" As one Hayato Gokudera suddenly appeared into his room from the windowsill, his body covered with a very conspicuous hood from head to toe.

(Somewhere in the background, G facepalmed.)

"Yes, Giotto-san!?"

"Thou shalt protect Tsuna from any harm, while thy am confined by them—am I clear!?" whilst the four-year-old saluted him and ran outside.

G deadpanned and smacked Giotto's head with his free hand, "do I want to know how and why?"

"Oh, Fon-sensei said kids like make-believe games, so I made one with the younger kids so if I'm oots—that's short for out-of-Tsuna-sight, by the way—I'll task them to keep an eye on Tsuna and give them points to trade for candies and stuff—it's been pretty neat actually!" Giotto beamed, he looked like he was immensely proud of his "little project." "Basically just add goals, rewards, and structural ranks to them, and they'll do anything as I say to please me."

Somehow, the realization of Giotto knowingly building an army of silently stalking children didn't even surprise him anymore.

Rubbing his tired temples, G unceremoniously dropped the shorter teen with a thud ("Oww!") before sitting again to look over the mostly-filled paper, not even sparing a glare as Giotto tried to scoot away from his two friends.

"If I don't get that validectorian honors on my graduation in two years, you're going down with me."

"Add horror and slasher movies into the mix, and you'll have yourself a partner-in-crime, G." the raven-haired teen chriped, as if he was just making small talks about the weather, and not Giotto's demise.

"Guys I'm right here—ow! Stop smacking my head G—ow! Kaa-san I know you're laughing downstairs at me with Nero-sensei! Kaa-san! Kaaaaa-saaan! OW GETSU I'M SORRY ALRIGHT—OW!"

END

A/N: Just two chapters left and then off to eternal "completed" tag it goes, ha! (Or at least until I want to sporadically add things into this again, but shh) Anyway, I think it's a bit fitting to answer some of the reviews from the last chapter (at least the ones not from years ago), so uh...

Codename-SN: Yep, it's actually a bit too exaggerated for my tastes (as of recently at least) tbh, but since this is basically my humor-crack-easy-writing-ish story, I don't particularly care much about his characterization (honestly, I just want him consistently as "crazy bro-con," "questionably charismatic idiot," and "a jerky bff with a somewhat-heart-of-gold," if I managed to do it right and consistent, haha)

michiko-chan27: Haha, sorry about that, my writing "prowess" was still a noob back then (well, still am now, but at least I kinda matured right, haha), hopefully it's not that jarring in the newest chapter :)

BlueThief: Yeah, since Iemitsu's mostly MIA in the household, but still tries to visit every weekend and mostly dotes Nana (and also cower, but mostly dotes) (as a side note, if you're interested, he's in charge of the Vongola Family's Tokyo legal team (they're just a big multinational company in Japan but has Italian roots from the founder's background (an Italian refugee who became a Japanese via naturalization and built the company from the ground up there), still a super distant family of Iemitsu (by the way, Frederico, Massimo, and Enrico are alive and half-Japanese and Xanxus is adopted and is the youngest and most pampered by the older sibs), has a national branch in Tokyo (where he works, it's kinda far from Namimori by train), also Nana used to be Reborn's student back in middle school, she used to be a delinquent who used brute force before Reborn taught her how to use unnerving smiles and silver tongue instead, then married Iemitsu 'cuz "love at first sight" in uni, also no one knows how old the fedora man is tbh), Nana's basically the one running the whole Sawada Household madness and would whip her boys (or anyone in her sight tbh) if they disobey her (aka Giotto being a rebelling teen with disgustingly over-the-top bro-con tendencies, haha). If you're wondering abt the Daemon-Tsuna bit, you can actually see it somewhere in the previous chapters (I won't tell which part tho, haha). Also thank you for understanding, it has certainly been a ride writing this, but unfortunately, even my never-ending crack juices have to say no to this thing in the end :")) (Also, also sorry for the massive wall-of-texts dump /cries) (By the way, can't help but notice, you're one of the ogs(?) to follow the story, anyways, thanks for the support all these years, BlueThief! :D)

A clowns smile: Yep and still a proud member of the "still awkward at English" and "still continuously improve my English" club, haha, and as of recently I'm currently living in Surabaya, but because of the recent events I'm back living with my family for the time being, haha (Still stuck with homework tho, hmmm...)
