"Wait, you can see me?"

Tsuna tilted his head curiously, eyeing the ghost-man. Honestly, with what the guy was wearing and his general appearance, he was a bit hard to miss. It made him wonder how on earth nobody else saw him. "Well, considering you've been stalking me for the past five years..."

The man gave up on trying to keep calm, and just let himself jump back, jaw dropped. "What?! You've known this whole time?!" There was a breif pause as he let the twelve year old's words replay in his mind. "I'm not a stalker!"

Tsuna mentally laughed. Not quite the reaction I was expecting from this guy... The brunet nodded, sending him the most serious look he could muster. Whether he was nodding as in 'Yes I've known the whole time.' or 'Yes, you are a stalker, don't even try to deny your true nature~!' would forever remain a mystery to the ghost. It was probably both.

"You didn't answer my question." Tsuna reminded him, and the ghost paused, thinking.

After a moment, the ghost straightened, walking over to Tsuna from where he had been leaning against the wall near the kitchen. He stopped in front of Tsuna, a grim look marring his features.

They had an intense staring contest that lasted a good minute and fifteen seconds.

Light orange eyes narrowed, and the blond quickly raised a hand and snapped in front of Tsuna's face, making the brunet jump back in surprise. "You don't see me." The ghost said seriously. "I am merely a voice in your head."

Tsuna was not amused by this. Crossing his arms, Tsuna stared him in the eye. "Fine, be that way. Mind telling me your name though?"

The man looked a bit unnerved that his little trick didn't work, considering the kid was staring him directly in the eye. Not just looking in his general direction, so it couldn't be the Hyper Intuiton.

Tsuna could genuinely see him.

The man sighed, making a face eerily similar to a pout (NO! I'M NOT POUTING I SWEAR-!). There was another awkward pause, and the man straightened a bit, watching as Tsuna kept his gaze on him. "Call me Giotto, I'm your great great great grandfather!"

...

My what.

Tsuna's first incredibly intelligent words in response were, of course, "Wai-wha-?"

The ghost- Giotto, his brain reminded- gave Tsuna a rather overly-cheerful grin that looked so out of place yet so right on his face. It was a strange feeling that left Tsuna with a small headache.

Giotto toned down the flying flowers and sparkles that appeared out of nowhere, settling for a fond smile. "I've been watching for the past few years, as you may have noticed. I am, in a sense, what you'd call a Guardian Angel, I suppose."

Tsuna stared at the man, brown eyes glimmering with curiousity in the light. "Guardian... Angel?" He muttered quietly, trying to wrap his head around the concept. After all, the man didn't seem to act all that angelic.

Tsuna's great great times like ten grandfather was his Guardian Angel.

Guardian. Angel.

What the heck.

Seeming to sensse the twelve year old's internal war featuring the opposing sides of "THIS IS NOT NORMAL" and "JUST ACCEPT IT OKAY IT'S LIFE" and gave a small laugh, snapping the kid out of his thoughts to give him a confused look.

Ah, my descendant's way too cute for his own good, G would absolutely love him.

"Don't think about it too much," Giotto said with a quiet chuckle, sitting down next to Tsuna on the couch. "I'm really only here to observe and prepare."

Tsuna's brow furrowed slightly at that, lips curling downward into a thoughtful frown, "Prepare for what?"

Giotto merely gave him a knowing, almost mischevious grin. "Can't tell!"

Tsuna was starting to think this guy couldn't decide on his personality, was he goofy and childish, or wise and mature?

The brunet sighed in resignation. My great great great grandpa is my Guardian Angel... That's it, nothing can surprise me now.

Oh how those words would come back to bite him in the near future.

~KHR~

Over the next couple months, nearly a full year, Giotto and Tsuna got to know each other rather well. Turns out interacting one-on-one was a better way to know someone than stalking (I'm not a stalker, I swear, Tsuna-kun!).

Giotto had a rather interesting group of friends, as Tsuna learned. A rather rowdy, violent, loud, bunch, according to Giotto. Always at each other's necks, but he still loved them. Tsuna always got a good laugh with each and every story Giotto had to share, making Tsuna wish he had stories to share with his new- first - friend. Unfortunately, Tsuna lived a rather boring life, but Giotto seemed perfectly fine with that.

Giotto found the kid to be very bright, in his opinion. If he wasn't a Sky, Giotto would put his bets on Sun. The kid practically glowed whenever he smiled, and Giotto felt he'd go blind at this rate.

But aside from the overwhelming cuteness (Giotto had whole-heartedly embraced the title of Doting Grandpa, but Tsuna took to calling him Giotto-nii, claiming his physical appearance barely looked over thirty) and ridiculous amount of kindness that threatened to flood any room the twelve, now thirteen year old stepped into, the thing that really caught his attention were the Sky Flames.

Oh the poor, poor Sky Flames. The child's flames had been sealed, much to Giotto's frustration. He personally couldnt do much about it, but the way the kid's Flames roared and struggeled against the seal made his own ache in sympathy. So much potinteal, just locked away like that. Giotto had a feeling the poor kid's clumsiness originated from the sealing of his flames, it threw him off too much.

Seriously, who's bright idea was it to do such a thing? Giotto would strangle them for practically crippling his self proclaimed little brother (It was a good thing he didn't know it was Timoteo and Iemitsu who decided to do it.)

They both decided to ignore the fact they could actually pass for real siblings, after that one incident where Tsuna looked in the mirror one morning and just shrieked a high pitched "HIIIEEEE! GIOTTO-NII WHAT THE-"

It left Giotto's ears ringing and Nana oh so confused as to who this Giotto-nii was.

Fast-forward about a year, Tsuna, still unfortuanately nicknamed Dame-Tsuna by many though looking a lot better and having at least a little self confidence than before, opened the front door to find a fedora wearing, beady eyed, suit clad baby with a gun.

Giotto, who was right behind Tsuna, eyed the baby carefully, taking in the sight of the yellow pacifier with caution.

"Tsuna, keep your guard up," He muttered into Tsuna's ear. His own Hyper Intuition was screaming warning bells at the baby- no, Arcobaleno, his mind supplied.

There's a freaking Arcobaleno on the Sawada doorstep.

Tsuna nodded slightly, not taking his eyes off the baby. "Who are you?" Quick, simple, and to the point. Good.

The baby quirked an eyebrow at the response, "I'm Reborn, your new home tutor."

Reborn? Reborn... Reborn, Giotto's heard that name before... Reborn, Arcobaleno...

Tsuna wasn't impressed. "I think you have the wrong house, Reborn-san."

Reborn hid his dark eyed below the rim of his fedora, a small smirk gracing his face. Giotto didnt like the look he was giving them...

Nana walked out of the kitchen, lighting up at the sight. "Oh? Is this one of your friends, Tsu-kun?"

Tsuna glanced over at Nana disbelief laced into his tone. "No he isn't, Kaa-san, he's-"

"I'm the home tutor, Reborn." The baby said all too happily, making Nana squeal in delight.

"You must be talented to be a tutor at your age! Come in, come in!" Reborn nodded, walking into the house as casually as possible, much to Tsuna's chargin.

Reborn paused in the middle of the hallway, looking back over his shoulder at an area just above Tsuna's shoulder.

Right at Giotto.

Reborn pursed his lips in a contemplative manner, before turning to Nana, who seemed rather impressed at Reborn being a supposed 'genuis'.

Giotto was just freaked out. Tsuna, he could understand, but Reborn seeing him? Or at least, from what he could see, at least sensing his prescence. He took a step back, eyeing Reborn carefully.

Definitely dangerous.

The Arcobaleno finally finished his buisness with Nana, turning around and hopping up onto Tsuna's head (How can a baby jump that high?!). Reborn gave his head a little pat. "Take me to your room, Dame-Tsuna, I have a few things I need to tell you concerning your education."

Tsuna just sighed, completely done with the world at this point. "Alright, alright..." He made his way up the stairs, careful as to not trip with his apparent tutor on his head, Giotto close behind.

They shared a glance, letting chocolate brown and sunset orange do the talking.

Giotto eyed the hitman carefully, He's dangerous, be careful around him.

Tsuna gave a slight roll of his eyes, careful to not disturb the baby on his head. But he's just a baby! Sure he seems pretty intimidating for his age, but it's probably just a game.

The blond's eyes narrowed cautiously. No, not a game. My Intuition says he's dangerous, so please, stay cautious.

A quiet huff followed by a sarcastic smirk. Right, right mother.

Giotto's jaw dropped. Don't use that tone with me, young man!

...

...

It took a bit to keep Tsuna from outwardly laughing at his ancestor's expression. Pfft, yeah alright, I'll be careful.

Tsuna shook his head in disbelief as they made their way to Tsuna's room, Reborn hopping off and getting situated on Tsuna's bed. Tsuna gave a quick glance to Giotto.

Careful.

Got it.

Just because he was careful didn't mean he was ready for the bomb drop of "I'm actually a hitman, and my real job is to train you to become a mafia boss."

~KHR~

A/N: What the frick happened here, like 48 follows already after less than a week? How did that happen?

I should mention that I went back and edited the Prologue a little and added a bit more content in, not much, but it's there. I tend to do that to chapters after publishing, so if I added anything to a previous chapter, I'll say so in the next update.

I just realized... in the prologue I said I was aiming for a Papa Giotto but instead we get Big Bro Giotto... meh, close enough. Everyone's probably OOC, agh... First time writing Reborn too, so that just makes it worse. Just take it as Giotto hammering in a little self-confidence into Tsuna over the year.

Thanks a lot for reading, I'd like to hear your thoughts on the story so far in the reviews!
