Hey guys,

This fic is a little something I wrote in celebration of my KHR Fic 'A Grieving Sky' reaching 100 favorites. I have no idea whatsoever how that happened but I thought that this was the perfect occasion to write my very first crossover. I originally meant for this to be a one-shot but now I'm considering continuing this as it was pretty fun to write. So let me know if you want me to continue this or not!

Disclaimer: I don't even own the laptop I am currently typing this out on. Owning KHR or KnB is farther than my farthest dreams.

Kagami was not having a good day. First he had got a 27 on last week's maths test, then it turned out that he'd forgotten to bring his bento and had to share with Kuroko-who only had store-bought rice balls-and when the final bell had rung the teacher has held them back to lecture them instead of letting them get to practice. Needless to say, Kagami was very annoyed. He did not think his day could get any worse. As if on cue, the speakers buzzed.

"Hello students of Seirin High, this is a special message for a particular student so feel free to ignore it."

The voice was male, gruff and obviously foreign. This was further proven when the man spoke up again, only this time in Italian. Kagami only knew because he'd had an Italian friend back in the States and was almost fluent in the language. The message itself though, shocked him to no end.

"Hello Decimo's son, looks like we've found you!" Beside him, Kuroko tensed up. "And to make sure you can't run away, we've got your friends here with us. That's right, we're currently in the gym with your team and they all look pretty damn terrified. Can I just say, I'm quite enjoying their scared little faces."

That made Kagami grit his teeth. He felt a dark aura around Kuroko, which he had come to take as a sign that the smaller boy was pissed. Wait, why was he pissed? He couldn't have understood the announcement just now, right? Or could he? Since when did Kuroko know Italian of all things? But he didn't have enough time to dwell on that as the man started speaking again.

"If you come quietly we'll see if we can negotiate something for your friends' lives. You have ten minutes before we started shooting, so decide quickly Decimo's son"

"Those bastards!" Kagami hissed, turning to Kuroko, only to find him gone.

Kuroko had sneaked out of the room the moment the man on the speaker had stopped talking. The boy was furious. How dare those idiots threaten his team, his friends, to try and get to him! Now he was really mad and those Mafiosi were going learn firsthand just how big a mistake they had made. His sadistic side was merrily thinking up all the ways he can demolish those idiots who had threatened the team. But first, he had to deal with a more urgent matter.

"Kagami-kun could you please stop following me?"

"Oh hell no!" Replied the red-head. "Kuroko what the heck is going on? And how do you know Italian?"

"I know Italian because most of m family lives in Italy, where I myself have spent half my life. As for those men, they're here for me. They intend to use me to either blackmail or get back at my father. He's quite an important man, you see, so it's only natural he'd have enemies."

"But if that's the case, you can't go there! I mean, I know that the team's in grave danger and all, but still, there must be another way. You can't just-"

"Don't worry Kagami-kun. I'll be just fine." Kuroko said cutting the basketball ace off.

"What the heck are you on about? You ca-" Kagami tried to say, only to be cut off yet again by his Shadow.

"I've lived my whole life with a target on my back, Kagami-kun. Today is not the first time something like this has happened and it's definitely not the last either. I've been trained to handle situations like this one so I'll be fine. Trust me."

"Kuroko.." Kagami said after a moment's silence. "Just who exactly is your father? And don't give me another one of your half-assed excuses. I need the truth."

At once, Kuroko knew that his friend meant business. Seems like he wouldn't be able to lie his way through this one. Though, he thought to himself, maybe telling Kagami-kun wont be too bad. He did feel bad about keeping things from his best friend. But up until now, it had been an absolute necessity. The bluenette* took a deep breath as he started walking again, motioning for Kagami to follow.

"You know Vongola, right?" He started.

"Of course I know the largest, most successful corporation on the planet. Even I am not that dumb."

"Well, that's not all there is to it. The company is actually a front as well as the legal counterpart of the Vongola Famiglia. It is one of the oldest and the most powerful Mafia Famiglia in the world. My father is the Decimo, as in the Tenth Boss of Vongola. Though most people call him the Neo Primo or the second coming of the First."

"Yo-you're the son of a Mafia Boss!?"

"Yep." Kuroko said casually, as if it was nothing. "But dad's not a bad guy. When my ancestor created Vongola about 400 years ago, it was just a Vigilante group to protect those who couldn't fight for themselves. Though when Secondo took over it turned into the dark organisation it has come to be know as. When dad took over seventeen years ago, it was with the intention to bring Vongola back to its original glory. And he's made tremendous progress too, but along with that he has also made many dangerous enemies. Some of whom are just beyond those doors."

"That was when Kagami realized they had reached the hallway that led to the gym. Kuroko quickly ducked into a side-room, pulling Kagami with him. As Kagami went over all the new information he had just been presented with, Kuroko was busy punching numbers into his cell phone. Moments later he started talking.

"Hello, Hibari-san? There's a bit of a situation here at the school...It's a H-11-26...No, I can handle it, I just need a Clean Squad...Twenty minutes? That's more than enough time...Yes, I'll be careful...No, please don't call him, he'll just worry...I know...Fine, got it. Bye."

"Clean Squad?" The red-head asked quite reluctantly.

"You'll see. Now stay here until I call for you. There's enough civilians in the line of fire as it is."

Kagami would have protested but the way Kuroko had said those words hinted quite blatantly that there was absolutely no room for argument. Not to mention the boy had conjured up a gun, seemingly out of nowhere. All of a sudden the previously harmless looking boy had turned into something dangerous, something he would not want to mess with in a million years. So Kagami shut up and stayed put.

Gasps and panicked yells sounded from the gym next door, followed by gunshots and panicked screams. Yet somehow, Kagami was not worried. Maybe it was because of how confident and dangerous Kuroko had looked earlier, but he was sure that all of his teammates would come out of there just fine. And he was absolutely right.

It took exactly seven minutes before a very confused and slightly scared looking Koganei-senpai came to fetch him.

Inside the gym was quite a peculiar scene. There were exactly ten grown men in gray suits, huddled in a far corner of. They were all bruised and battered and some even sported gunshot wounds; though they were all in non-fatal areas like the shoulder or the kneecap. One person even had a grazed cheek. Mostly though, they all just looked really scared. Bullet holes littered the room yet not a single member of the Seirin Basketball Team had even a single scratch. Not even Kuroko.

Kuroko. Now did that kid know how to look terrifying. He was standing in front of the dog-pile of mafiosi, his gun aimed steadily at the group as he chided them. If Kagami though the boy was scary before, this was on a complete other level. He almost felt sorry for those poor men.

"You've got some nerve, pulling a stunt like that. Then again, maybe you and your Boss are all just really stupid. I'd say it's the latter. After all, only a moron would underestimate Vongola to such an extent. Did you really think you could pull this off? It would benefit you to not think so lowly of the Ex-Arcobaleno's tutelage.

Coach and the rest of the team gave Kagami questioning looks who in turn tried to explain the situation as briefly as he could.

"Kuroko's been keeping quite a few secrets. Turns out his dad owns Vongola Corporation. He said he's had training to deal with such kind of situations as there is always a threat to his life due to his father's status. And don't look at me like that, I only found out ten minutes ago, myself."

The Seirin Ace left out the Mafia bit since he did not think Kuroko would like the others knowing. Yep, there was no way in hell that he was ever getting on that guy's bad side. And even though he knew Kuroko would never actually hurt him in anyway-that kid was too kind and forgiving for his own good, just take the GoM for example-it still didn't hurt to be careful.

The gym doors burst open and in came a group of five; three men and two women. All dressed in fancy suits. Two of the men stopped by Kagami's group while others went to Kuroko's aid.

"You are early, Hibari-san." Kuroko said to the tall raven-head as he made his way towards the two, leaving the pitiful criminals to the new arrival that Kagami guessed was the 'Clean Squad'.

This 'Hibari-san' was the guy Kuroko had called earlier. The man had quite a menacing air to him and looked like the kind of person who could kill a person without batting an eyelash. Beside him stood a big, buff guy with the oddest of hairdos that he's seen in his life.

"The Omnivore was yelling at me." Hibari answered, almost as if he wanted to whine.

"Did you really have to call dad, Hibari-san?" Kuroko pouted.

"Did you really think I wouldn't, Tetsuya?" Hibari retorted. "Your father and the Carnivore would be at my throat for weeks about it. Not to mention how your Godfathers would react. And of course let's not forget what your step-mom Kyoko and your Aunts would say. Nope. Too many annoying outcomes."

"It's okay Sawada-kun. Tsuna-san isn't mad or anything. Just worried."

"That's what I don't want, Kusakabe-san!" Kuroko exclaimed.

"Wait, wait! Back up a second!" Hyuuga-senpai spoke, having finally gone back to his normal self. "Sawada?"

At that everyone looked to Kuroko with confused looks. The Shadow only sighed.

"Um, when I moved back to Japan at the start of Middle School, I didn't want to grab any unnecessary attention so I took on the alias of Kuroko Tetsuya. My real name is Sawada Tetsuya. I'm sorry I kept all this from everyone but I just really wanted a normal life is all. Had people known who I was then things like this would happen all the time and I would just have to go back to Italy."

"Not that I don't like it back at home." Kuroko added quickly, more towards Hibari than anyone. "But I just really missed Japan."

"Oh."

"Yeah, so um, I'd really appreciate it if you didn't mention this to anyone."

There was a collective murmur of 'okays' from the group and Kuroko smiled, relieved. That was when Hibari's phone started ringing. The ring tone sounded like a school anthem and Kagami wanted to snicker but held himself back, lest the scary man murder him.

"Omnivore...I didn't need to. He took care of it...He's fine...Yes he's right here...Hn. I'm putting you on speaker, his friends are also here."

"Wait, Hibari-san!" Kuroko protested. Too late.

"Sawada Tetsuya!" A smooth, exasperated voice rang through the room. "Must you be so goddamn reckless all the freaking time. Would it have hurt to wait FIVE minutes for reinforcements? Seriously, do you have any idea how much you make me worry? I swear if your mother was here, she'd have a heart attack hearing about the stupid things you do!"

"Um...sorry?"

"Is that-"

"Pause your fatherly ramble for a minute Dame-Tsuna." Said another voice. "Good job Baka-Tetsu, looks like you aren't slacking off on training."

"Stop encouraging him, Reborn!" At that, Kuroko, Hibari and Kusakabe all sweat-dropped.

Kagami decided then that he really wanted to meet the rest of Kuroko's family. They seemed like interesting people. When he told the boy this later that evening though, he looked at him like he had gone another head.

So, what do you think? Is it good? Bad? Preposterous? Let me know in a review. Also do tell me if I should continue this or not.

For all of you waiting for the next chapter to AGS, it'll be up by tomorrow, I promise.

Till Next Time!
