OooOoOooO

AN: I'd gotten into reading this crossover for a while and plot bunnies overloaded my brain and this came up. I adore KHR and HP - the reason I fell in love with this particular crossover.

Important Note: I don't know if I'll follow appropriate timeline (canon) for KHR but for HP, the war happened earlier than any of the wizards expected (around when Harry is maybe about eight to nine) so his past would be gradually introduced into the story. Harry here is strong but not Super. And remember, in judging strength, they're still children - so what they are now are still potentials and will definitely grow into something more.

Please enjoy this chapter! :)

Chapter 1

Sawada Tsunayoshi sighed as he listened to Gokudera Hayato and Yamamoto Takeshi go at their argument again. It had been a few weeks since the incident with the Varia and it had been really stressing. So he was just glad that everything seemed to go back to normal. Reborn was back to tutoring–which the infant hitman mostly associated synonymously with torturing–him again and generally making his life miserable. Hibari Kyoya was still the same aloof and rather violent leader of the Disciplinary Committee. Mukuro's location was unknown at the moment while Ryohei was persuading him, rather unsuccessfully, to join the boxing club with him.

Lunch time had already started so they had some free time to themselves. Just as his gaze shifted to his other classmates, one particular caught his attention.

It was the new student.

Hinamori Jun was definitely an unknown, having only been in his class for the majority of two weeks. The boy was quiet but polite–Tsuna had tried to talk to him on occasions–but didn't like interacting with people. The boy wasn't pompous about it but had obviously just wanted to be left alone. Most of the student body, though, had other ideas. The higher years sneered at him while his classmates either ignored him or eyed him with disdain. He was also somewhat awkward socially–painfully so that he reminded Tsuna of his self before he met his friends and became involved with the Vongola. Hinamori's situation was almost reminiscent of 'Dame-Tsuna' with the way the majority of the school looked down on him except for major details that came with the new boy.

For one, Hinamori is a foreigner.

Though, the boy claimed to be half-Japanese from his mother's side. The absence of any oriental or Asian features in his appearance would actually prove the contrary. The next thing, Hinamori was smart. He wasn't at the top of their year but got good enough marks to pass all of his subjects almost breezily. The boy was only somewhat shy, mostly just quiet, but had the necessary backbone if provoked. And lastly, Hinamori seemed to be the only person that Hibari Kyoya tolerated on friendly terms, even going as far as to only give Hinamori a warning instead of the usual brutal beating he bestowed as punishment to late comers or 'herbivores'. Apparently, they knew each other before Hinamori transferred. The last fact was what probably protected the new student from their school's wrath entirely.

The boy was a little on the short side, scrawny build, round-rimmed eyeglasses, awfully messy ebony colored hair, and the most intense green eyes that Tsuna had ever seen. Naturally, Gokudera was suspicious of him with his apparent foreign origins until Hibari's not-so-subtle threat about biting him to death should he mess with Hinamori. Yamamoto always got this uncomfortable look in his eyes whenever the topic about the new student came up in conversations–as if he knew something about the boy.

And maybe, seeing himself in Hinamori Jun–the somewhat shy, polite, and socially-awkward persona–was what always prompted Tsuna into trying to befriend him.

But the boy just gave him a small pained smile before politely refusing.

Not like he gave up though, Tsuna still tried to persist in befriending Hinamori.

Tsuna just didn't like seeing the other boy so alone–even if seen with Hibari, there was a certain distance about him that made Tsuna think of him as unreachable. It was like, he trusted Hibari but didn't want to get attached or involved at all. And Tsuna knew very damn well that similar thoughts were reciprocated on the Prefect's part.

He sighed again as he watched his classmate stand up from his seat and leave the room by himself, again, just like always.

"Why the hell are you looking at that brat again, Juudaime?" Gokudera cut in as he grunted and sent a baleful glare towards the other boy.

Tsuna looked at his Storm Guardian in surprise.

"E-Eh?" He stuttered suddenly, startled. "W-What are you talking about?" He smiled nervously at the silver haired boy.

"You shouldn't be wasting your time on someone like him," Gokudera scoffed in disgruntlement. "He's not worth it if he keeps rejecting the Juudaime's offer! Just let him be," He scowled as he crossed his arms over his chest.

"Stop speaking so insensitively," Yamamoto interjected with a frown and Tsuna had started to notice that his dark haired friend always got unusually solemn at the mention of their new classmate.

"And I don't think being alone is any great, Gokudera-kun." Tsuna's eyes flashed with sadness as he remembered the times when he used to be ridiculed.

That seemed to have sobered his friend up from his casual resentment of Hinamori, knowing how his boss was treated before they became friends. As soon as he got over his suspicion, Gokudera had reluctantly followed Tsuna's lead to befriend the bespectacled boy. And he held a light grudge of how the other had refused the Juudaime's offer. Tsuna was touched and warmed that his silver haired guardian was looking out for him, but it still didn't give him any reason to badmouth their dark haired classmate.

And Hibari would maim Gokudera if he ever heard him, at that, Tsuna held no doubt.

As he thought back on his new classmate, Tsuna shook his head with a sad smile. At least, there was someone looking out for him, or as close as it could get with someone like Hibari Kyoya. Something the brunette could have only wished for before Reborn came along.

O.o.O

Just as they were about to go home after school, Tsuna and his friends tensed up as soon as they saw Hibari Kyoya storming to their location.

Tsuna still hadn't gotten over his fear of the Prefect since the raven haired teen made no action to prove the contrary. Yamamoto and Gokudera were now openly wary of Hibari since they had already seen just how truly dangerous he was–his open violence was not just for show after all. But the reason that they were on edge was the familiar cold gleam in his eyes that they had only seen when he was fighting Mukuro or Belphegor. His face was carefully neutral but his movements were stiff and rigid, as if visibly restraining.

"Leave Hinamori Jun out of your family's business, Sawada Tsunayoshi." He instantly stated tightly as soon as he came near enough of hearing range. Tsuna expertly ignored how Hibari had singled himself away from the family just as always.

Gokudera instantly moved to Tsuna's side while Yamamoto eyed him cautiously.

Tsuna's eyes, though, widened at the mention of his classmate and what Hibari's words actually meant at the mention of family and business.

"W-What do you mean? I-I didn't even mention–" He stuttered out in anxiety but also in rising panic, he had never even hinted anything about the mafia to his classmate so what was Hibari trying to say?

"He had received a note from that baby two days ago." Hibari cut him off with a glare, bringing out a crumpled sheet of paper from his pocket and tossed it carelessly to Yamamoto who barely caught it.

To: H. J. P.
You are being given this opportunity to join the Vongola Family under my approval.
Please refer either to Sawada Tsunayoshi or Hibari Kyoya for inquiries.
Reborn

The note was crisp and precise, straight to the point and leaving no other room for hidden motive. Tsuna blinked as he eyed the familiar scratchy penmanship of his tutor but he couldn't help but inwardly wonder about the initials. He knew that H and J stood for Hinamori and Jun but where did P come from? He turned to his friends and saw that Gokudera was eyeing the paper with apprehension while Yamamoto frowned warily.

"I-I didn't know," Tsuna finally admitted helplessly as he mentally lamented where Reborn was going with this.

Hibari's eyes narrowed.

"Wait, if Hinamori-san received this two days ago, then why are you just telling us now?" Yamamoto questioned in confusion while Gokudera nodded decisively beside him.

"Yeah and Reborn-san never told us about this!" The silver haired teen defended almost irately, returning the Prefect's glare.

"It's none of your business why we didn't inform you sooner, herbivore," The raven haired teen retorted sharply. "But I am relaying this fact to you now since Hinamori Jun is nowhere to be found since lunch time and is last seen with that baby. Tell me where he is before I bite all of you to death." He threatened them as he brought out his tonfas, his voice deep and ominous while his face didn't shift from its indifference.

"You want a fight?" Gokudera growled as he brought out dynamites from his pockets.

Tsuna flinched at the sight of the Prefect's weapons but hastily moved between the two. Yamamoto was already holding off Gokudera by the arms while whispering furiously to his ears. Hibari just watched him intensely with a neutral face.

"Please, stop this, Gokudera-kun! Hibari-san!" The brunette boy pleaded as he stared at them simultaneously in nervousness, before finally settling his gaze on Hibari. "And we really don't know where Hinamori-san is! We didn't even know that Reborn made contact with him." He reasoned desperately, not wanting to see them fight.

Hibari eyed him for a moment longer and Tsuna refused to look away.

Then in one swift move, he had hidden his tonfas and whirled abruptly to walk away.

"Be as it may, you're tutor is treading on forbidden grounds, herbivore." Hibari warned him in a dispassionate voice, tone cold and apathetic.

O.o.O

"No, you know I can't," Hinamori stated tightly, eyes barely restraining rage from showing. "This is as far as you can get, Reborn." He gritted out angrily as he glared at the smirking baby in front of him.

Reborn just lowered the front of his Fedora hat, eyes gleaming calculatingly as he stared at the ebony haired boy in front of him. It had been such a surprise when he heard Dame-Tsuna being depressed over a refusal of friendship from a new student named Hinamori Jun. Not recognising the name, naturally, he had his sources looking onto him. Which was unneeded once he had seen the boy. The green eyes and the lightning bolt scar was a primary dead giveaway. And certain connections had hinted about a war from where the boy came from. And surprisingly enough, the boy knew of him.

After all, considering from what family the boy descended from in his mother's side, it shouldn't have been surprising–but the boy's mother had been disowned from the line so he found it perplexing for Hinamori to know of him.

And those wizards refused to acknowledge the existence of mafia so that was left out.

It was intriguing, really, to find this boy glaring back at him defiantly even if he knew exactly what Reborn was. If it were any other person, he would have probably shot their kneecaps in to force them on their knees. He could feel the power emanating from him and could see it pulse in the vibrant green eyes. He wondered what really pushed Hinamori to come over here in Japan. And then he saw Hibari Kyoya with him and instantly knew. He had suspected something from the Prefect the moment he saw him on his first day with Tsuna in school and Hinamori's presence had proven it.

"You can say no numerous times but we both know that this won't be the last time," He remarked casually with a sweet smile, deviousness shining through without even trying.

"I'm not even suited for the job!" Hinamori tried to reason, rather unsuccessfully, to emphasize this. "And they don't need me, from what I've heard from Kyoya, they're doing finer than anyone can hope for considering their lack of experience." He stated seriously and there was a hint of insecurity in his eyes that made Reborn think of Tsuna.

"But they're still naïve," Reborn quipped back coldly that made the boy flinch. "They still don't understand that this isn't just a game or an organization built to fight. They still can't realize the necessary risks, that lives may be lost due to a careless mistake. They know but they do not understand. Unlike you." The small baby intoned almost thoughtfully, his expression blank as he stared at the skeptical boy.

"What do you expect?" Hinamori questioned incredulously, his eyes wide in disbelief. "They're kids!" He told him in a way as if it should have been very obvious.

"And you're not?" Reborn raised an eyebrow in challenge as the boy tensed. "You're only what? Twelve? And you can already comprehend the reality of this world we live in. The family would need someone like you who would understand them when it slapped them on the face, especially Dame-Tsuna. I may be his teacher and have personal experience of this but I can't push my beliefs on them. I may look like a kid but I've already gone past their age."

"Thirteen, actually." The boy calmly added before looking sad and grave. "And no, I can't." He smiled weakly at the baby.

"Why not, Harry?" Reborn ignored the way the boy had flinched at the name. "Surely, someone from your mother's line, you would know not to underestimate your own self." He raised an eyebrow at the boy almost sardonically.

The boy's face crumbled as he stared at Reborn warily, almost nervously.

"Y-You know?" Hinamori stuttered quietly as he anxiously adjusted his glasses, the sudden timidity reminded the hitman of his own student. "But then if you do, you should also be a-aware that they'd rather see me dead than let me even claim their name?" He gave a small bitter smile as green eyes gazed at Reborn so intensely, as if silently prodding the hitman, almost making him feel exposed.

Then suddenly, he straightened as he understood the double meaning of the statement.

"They tried to eliminate you," Reborn concluded darkly, his eyes narrowing as Hinamori gave a sarcastic smile–too widely stretched that had his eyes squinted almost shut.

"Why, Reborn! One would think you actually care!" The boy stated mockingly in a dramatic way. "After all these years, after leaving me to the hands of those people, when you were supposedly begged by my mother to take me in, in case the worst happened, you suddenly care!" The tone ended with a sharp edge of anger and. . .hurt.

Reborn turned rigid as he glared frostily at the boy.

"I have responsibilities to take care of–one that can't be jeopardised just to look after a brat like you." He growled as Leon crawled around his arm down to his hand and instantly transformed into a familiar pistol–aimed at the now incredibly stiff boy. "I take it that you've seen their Will." He observed with pursed lips and that explained why the brat knew of him so suddenly. Though, something was telling him that that wasn't all, the brat was hiding something.

It irked him that the boy's family through his mother's side–the real one, not the foster home that the wizard people forced Hinamori to–had tried to kill him. But that Famiglia had not honoured their agreement that they would leave the boy alone. The Ninth had ensured that the boy was at least under Vongola's supervision while Reborn was still connected to the family. That was until they lost him to that blasted magical community. And if his contact's information rang true–which was harder to gather than one would like to admit–that world was in utter chaos and under the destruction of war, of all things. And though, he wouldn't admit it, Reborn had forgotten to check on the boy once he had arrived in Japan to nurture Dame-Tsuna to be an acceptable Vongola Decimo. It wasn't until he recognized Hinamori for who he was–that he remembered and had asked the same contact about the situation. The war had ended, many lives wasted, still in complete pandemonium, and this boy had survived and disappeared. Until Reborn saw him in Namimori. Sadly, that was as far as he can get and he disliked the fact that the information was rather vague. No specific details whatsoever.

The smile on Hinamori's face instantly dropped as he gave the man his best chilling glare.

But Reborn just quirked an eyebrow.

"That's right," Hinamori nodded in insincere agreement. "You don't have time and I genuinely doubt that it will change. You have your duties and I'm no longer part of it." The boy's smile was small and it held a great deal of disappointment. "And don't you dare use those kids to make me join you, you've already pulled several people enough into it. I've seen war, seen death, and I've already got my small share of the mafia to make me want to avoid it as much as possible." The boy's voice had gone small and despondent as he sighed.

"So you've been aware of the mafia and is still alive?" Reborn murmured thoughtfully instead as if he just hadn't heard the boy confessed how he had basically forsaken his world. "Now, you've just convinced me that I made the right choice." He declared firmly, voice going deeper than the normal high-pitch.

Green eyes narrowed in frustration.

"Didn't you hear what I just said?" Hinamori questioned furiously, hurt and angered by the dismissal of his words. "I refuse to even integrate myself in that world. Being the famous child of the magical community in England is enough and I don't need to associate myself with a powerful position that will basically make me a target."

"What about Tsuna and his friends?" Reborn asked monotonously as he shifted the pistol in his hand.

"I don't need anyone and they especially don't need someone like me," His voice was firm and Reborn would have believed him if he couldn't feel the bitterness exuded from the very words–it spoke of loss and defeat, a self-accepted fact for Hinamori.

Just like when Tsuna truly believed that he wasn't capable of anything at all, that he would never have friends, and that he wasn't the right choice as the Vongola Decimo.

And Reborn instantly knew that Harry–or was it Hinamori now?–was really the right choice to be Dame-Tsuna's advisor. It might have been easier to convince the boy if he didn't dislike Reborn as much as he did now–eyeing the Arcobaleno with scorn and disappointment.

"Alright," The hitman nodded as Hinamori blinked in sudden surprise at how agreeable the infant was being.

The ebony haired boy then narrowed his eyes in suspicion.

"There's a catch," He concluded and Reborn nodded in satisfaction at the perceptiveness.

"I wouldn't bother you anymore on one condition," Reborn crossed his arms over his chest as he glared at the green-eyed teen who was staring at him with apprehension–reminding him of a woman who used to possess the same eyes.

"Let's h-hear it," Hinamori stated uncertainly, dread filling him as he watched the cunning gleam in the hitman's wide eyes.

"Give them a chance, or at least, Dame-Tsuna." Reborn offered carefully as he saw wonder enter those hardened emeralds and he had to think what the world was coming into if children's innocence couldn't be preserved anymore.

"No," Hinamori declined with a sigh. "I'm through with giving people chances. If they really deserve it, why not earn it for a change, then?" He gave a small tired smile.

The boy was slightly surprised when Reborn's aura suddenly turned sinister.

"Is that a challenge?" The infant smirked at him.

O.o.O

Hinamori should have expected this.

When Reborn took something as a challenge, it meant that the hitman would do anything to win. Anything. It was never a good idea in the first place–though in his defense, he hadn't actually issued it as an unspoken or official one. Reborn just made it so. And he had realized a little too late that it was a trap. He was trapped. Kyoya was extremely annoyed by that fact since the older boy expected him not to fall for something so obvious. So now, temporarily, he was primarily ignored during school hours–only deeming his presence worth a glance when they got home.

He had never actually met Reborn in person until that first meeting by the park. But he had heard enough from specific people to know what to expect, at least, the gist of it.

So it shouldn't have been a surprise when Sawada and his friends appeared by the gate of their house–with Reborn. The mansion was large, he knew but Kyoya never cared, and yet, he knew that the Prefect would be aggravated to see the people whom he considered to be 'herbivores' in front of his house without invitation. Reborn's idea, he realized with chagrin. But what really disgruntled him was that, no one from his school knew that he lived with Kyoya. It was a guarded and well-kept secret. Well, obviously, it needed to be improved if Reborn had easily deduced it and brought them here.

The situation would have been salvageable. Hinamori could just lead them away from the place and pretend that he was just visiting–after he changed out of his pyjamas. That was until Reborn blasted the gate to oblivion and invited himself in.

He grimaced, Kyoya would be displeased, no doubt awakened by the loud explosion it had caused.

And if there was one thing the Prefect hated the most, it was being interrupted from his sleep. The older boy didn't look like it, but Kyoya certainly loved his sleep and rest–for the sole reason that it was relaxing and rejuvenating in preparation for a fight. It was the only thing Kyoya allowed himself to be immersed with aside from the Disciplinary Committee. So being pulled away unexpectedly from it, Hinamori had no doubt that the older boy would be furious.

So he sighed and just resigned himself to his fate. Opening the door cautiously, he was greeted with the sight of a frantic Sawada Tsunayoshi, a worried Yamamoto Takeshi, an annoyed Gokudera Hayato, and an extremely smug Reborn. Though, they froze as soon as they caught sight of him. He adjusted his glasses at the perch of his nose and felt a headache brewing, even Draco and Ron weren't this rowdy despite their personal feuds and arguments with each other. And that was saying something considering the bad blood between the two's families until they had reached a bitter understanding to work together.

"Ciaossu." Reborn greeted with a smirk, eyes gleaming uncannily.

"H-Hinamori-san?" Sawada stuttered, completely surprised if he had to guess. Though, he paused at the name and reminded himself that it was his new identity now. It was still a foreign concept to him and he still had some getting used to.

"You live with that bastard?" Gokudera questioned incredulously, having zoomed onto what he considered to be the most important.

After all, the name by the gates was certainly 'Hibari' and not 'Hinamori'.

"Gokudera-kun!" Sawada reprimanded in a squeaky voice before turning back to Hinamori. "W-We're so sorry, Hinamori-san! Reborn didn't mean to blow your gate–" The brunette tried to apologize, his voice quite shaky as Sawada probably realized just whose house they had stumbled upon. Hinamori would be wary too considering how territorial and possessive Kyoya was when it came to material possessions. He supposed that the boy had the right to be scared.

"He meant it, Sawada-san." He sighed tiredly. "Reborn absolutely meant it to call our attention." He sent a baleful glare at the infant's way. "Well, you certainly had it now." He stated coldly, he didn't appreciate people barging in like this especially when he was so unprepared.

Sawada flinched slightly at the cool tone while Yamamoto looked vaguely guilty and Gokudera bristled.

But what irked him the most was Reborn's satisfied smirk.

"Dame-Tsuna, meet Hinamori Jun," Reborn stated mockingly, as if scorning him with the false identity he had built up. "My godson." He finished off with the barest hint of anger and a little bit of grim determination as if the ebony haired boy was a mission he had to accomplish.

That was probably what made him the most livid. After years of not even initiating some kind of communication between them, that fucking hitman still had the gall to claim the position of being his godfather. Not to mention, he wasn't a challenge that needed to be fulfilled. He told himself that he would ignore it but it still actually hurt to know that the remaining person he had expected to depend on–after learning of him from his parents' Will–was really just another person who abandoned him. Something that Reborn had readily admitted during that meeting. Hinamori had given him a chance, he had hoped, and Reborn had crushed that so easily.

Maybe, things were happening too fast. And not having any control over the situation made that anger swell more than he would usually let it. He hated that feeling–especially when he remembered the time that Dumbledore had chosen to keep him in the dark. He had been twelve and they were in a war where the main instigator wanted him dead, that burning resentment as he recalled the helplessness–he closed his eyes and took a deep steadying breath.

He opened them and stared icily at Reborn who just returned it calmly.

Sawada was gawking, paler than usual and was staring at him with horrified fascination. His eyes appeared as if they would fall out of their sockets anytime soon. Yamamoto was frowning and Hinamori remembered the time that the boy had talked to him, how Hinamori had tensed under the hand on his shoulder and the apparent discomfort he had expressed when being in a lone classroom with only one person he didn't know. He knew that the boy had known those signs, not that he had freely given them but things were still too fresh, and Yamamoto had shown concern for him when Sawada and Gokudera were away from sight range. While Gokudera was openly gaping though as disbelief colored his features.

"Y-You're Reborn's godson?" The brunette stammered helplessly, looking as if the very concept was foreign and terrifying.

From what he had gleamed from Kyoya, Reborn wasn't exactly the ideal tutor with his Spartan methods–even if he did a good job of protecting these kids' innocence from the reality of the much crueller world. He had to bite back a sigh, he talked as if he wasn't a kid himself.

"Officially, he was named my godfather." Hinamori at least felt kind enough to explain but his eyes were carefully trained on Reborn. "But in reality, he hadn't been much of a godfather. I don't appreciate you barging in like this, Reborn." He stated a little crossly, irate and tired from the hitman's excursion.

"Yet you came here in Japan for me?" Reborn innocently questioned, a sly smirk on his face as he tilted his hat down.

Hinamori didn't speak but his angered green eyes spoke volumes. The ebony haired boy's grip on the door tightened until his knuckles were white and despite being obviously pissed off as his gaze glittered coldly, he looked as if he was about to cry in frustration.

"So, you live with Hibari-san?" Yamamoto cut in, obviously trying to shy away from the current subject as tension filled the air.

"Yes," Hinamori answered tightly, might as well admit it since he was already caught red-handed.

It seemed that Gokudera still couldn't wrap his head around the idea.

"B-But, why?" The silver haired boy exclaimed in incredulity, as if the idea was alien to him–to them, more like it. But Hinamori realized that Reborn probably knew by now if the hitman had known where they lived. And still, Gokudera's perplexity over the situation was understandable, almost like the boy was asking if why he would want to live with Kyoya, especially if the older boy wasn't the most hospitable person Hinamori could name.

"He's my half-brother." A chilling voice responded in an icy tone from behind Hinamori, rougher from being just awakened from sleep and more ominous at the hidden promise of pain that would be part of their future.

Hinamori didn't bother looking behind him to feel the older boy's glare. Though he admitted to being startled at how freely Kyoya gave the information.

"They destroyed your gate," Hinamori deadpanned dryly, his green eyes straying to the chunks of golden metal. He never considered Kyoya's place as his, even if the older boy gave him permission to do as he pleased.

Sawada had apparently gotten another shock in hearing that he was Kyoya's half-brother, another addition to being Reborn's godson. Though Hinamori's words probably pulled him out of it and he was now looking quite panicky at the sinister presence of the Prefect. Yamamoto though looked thoughtful as he stared at Kyoya while Gokudera was practically speechless and of course, Reborn just nodded as if he was proven right, which was most likely.

"Fix it later," Kyoya sternly ordered, his glare trained on the unexpected visitors.

"Do I have a choice?" The ebony haired boy grumbled as he lightly grasped the brown bracelet in his left wrist, a red and golden feather design carved around it. It vibrated slightly in his grasp as his magic hummed within. But still, Kyoya was getting a little too used about the 'Reparo' charm.

And then, Kyoya finally decided to notice Reborn with his glacial gaze.

"You," The Prefect growled in contempt.

"What about me?" Reborn smirked at the obviously displeased boy.

"R-Reborn!" Sawada exclaimed in obvious concern, a clear plead to stop provoking the older boy which Hinamori thought to be wise. He might still be simmering at the hitman's audacity but nothing could be that comparable to Kyoya's anger.

"Dame-Tsuna, shut up." The hitman retorted sharply as a green pistol appeared in his tiny hand, making the brunette flinch slightly. "The least you can do is to stay quiet after I make the proper introductions." The infant still had his infuriating smug smirk despite the callous warning in his suddenly deep voice.

Hinamori sighed warily as he felt Kyoya stepped in beside him. He ignored the subtle glare that was sent his way, after all, these people came for him and subsequently destroyed part of Kyoya's property. And the Prefect just disliked any kind of disturbances. Sure, he refrained from fighting Hinamori but it never meant that he was not annoyed. Reborn was making it worse though and he had to question what the hitman's true motive was.

"Hinamori is the Vongola Tenth Advisor." Reborn instantly cut into the chase as his eyes snapped to a very shocked Hinamori.

He knew that Reborn had taken his wry and bitter response on their first meeting as a challenge but to actually imply that he had no choice in the matter so suddenly made the anger earlier bubble into acidic rage. One of the large double doors ominously cracked loudly as his magic lashed out–making Sawada and his friends jump at the unexpected noise, their wide eyes trained at the splintered door nervously.

Kyoya sent him a disgruntled glare as his eyebrow twitched almost unnoticeably.

"You bloody git," Hinamori gritted out in English, his eyes narrowed coldly at Reborn. And if they imagined him without the glasses, Hinamori would look like a miniature version of Hibari Kyoya–down to the frosty expression.

It was a wonder they never really noticed the resemblance before.

Kyoya seemed to finally have enough and brought out his tonfas, though Hinamori directed his glare at the older boy at why he had chosen to react now than earlier. Kyoya had the habit of acting now and question later, so it was an irritating wonder for Hinamori's part. The others tensed while Reborn watched with detached amusement.

"Out, herbivores. Now."

There was no mistaking about Kyoya's threat as his weapons glinted sinisterly under the morning sunlight. Reborn just nodded as if he had gotten what he came for.

"Let's go," The hitman sternly commanded and the others wasted no time to get out–though Yamamoto sent him a cordial wave.

Hinamori calmed down as soon as they were out of sight, he blinked though when Kyoya's hand landed on his shoulder, conveying that the older boy wasn't letting him escape. He didn't have to wonder for long as Kyoya gestured to the destroyed gate and door.

"Fix."

Hinamori sighed and thought that Kyoya was definitely not a stable person after being just awakened.

O.o.O

"An advisor?" Tsuna cried out incredulously. "You don't have to involve him!" He yelled at the infant, his usually warm eyes were uncharacteristically burning with anger. Not another person to suffer in the mafia, was left unsaid but the brunette had successfully implied it. Weren't involving his friends enough? Hinamori was a good enough person–someone he had yet to know but someone he didn't want to be entered into the destruction that was the mafia.

"He's already involved in the mafia through his mother's Famiglia." Reborn just remarked casually, ignoring the scorching gaze of his pupil.

That stopped Tsuna short from his genuine furious tirade to stare at the infant, as did Yamamoto and Gokudera who were watching their boss vent out at his tutor. Their expressions went from confused to curious that was highlighted by demand on Tsuna's part–wanting more confirmation. The brunette disliked including people needlessly the most into his world and Reborn had the habit of doing just that.

"From where?" Gokudera gruffly questioned as the silver haired boy's eyes stared warily at darkening expression of Reborn.

"Ambrosio." The hitman growled coldly.

The boys were surprised since Reborn rarely let things get to him–but this was obviously a sensitive subject judging by his growing dark aura. But they didn't really know how to react, none of them had heard of the family and this had been the first time that Reborn had spoken of them.

"Does this mean that Hibari-san's part of the mafia all along?" Yamamoto chuckled, trying to lighten the atmosphere.

"No," Reborn shook his head.

"But Hinamori…?" Tsuna looked at the hitman imploringly, eyes concerned yet curious.

"I'm not sure of the details. They somehow got a hold of him when I wasn't looking." Reborn looked apparently displeased by this fact. "Especially when the Ninth had made an agreement with them on my behalf. But if I had to guess, it was only recently. I'll have Shamal look into it." He speculated mostly to himself, looking thoughtful.

"B-But, an advisor?" The brunette groaned out, though his voice still held question at what it meant.

Reborn settled himself comfortably on Tsuna's bed before smirking.

"Advisors aren't really a compulsory," The hitman started with a cluck of his tongue, as if partly disproving. "The bosses known to have one in the Vongola were the Primo, Secondo, Quarto, Quinto, Sesto, and Ottavo. Each boss has their own right-hand man but advisors are the Famiglia's right-hand man. They handle most of the documents in dealings, the finances, the contracts, agreement, and contacts of the Vongola. But mostly, an advisor is also the facilitator of the family–a boss makes the decision and is the pillar. The reason that I wanted Tsuna to have Hinamori as his advisor, aside from integrating him into the family, was that boy has already seen the real weight of the mafia and the dark portions of our system. He can much better incorporate the Decimo and his guardians into the real Mafioso instead of just having it slap you in the face too late." His statement was almost mocking but he exuded seriousness that called their attention.

And advisors were also the current core of the family, a diversion of interest from the current boss. It basically made whoever took the position the main target while the boss and his guardians manage the family. After all, he would hold the secrets and information regarding the family. And from what he had learned, Hinamori had the necessary resources too to better establish the Tenth Generation. But what made the boy most qualified in Reborn's opinion was that, he was powerful enough to maintain the position–after observing him. He had heard of enough stories about how the Secondo's advisor had been brutally assassinated or how Quinto's had cracked and almost managed to betray the family. Tsuna just didn't have to know those details.

But Reborn still couldn't fathom why the Ambrosio Family would target a child of their disowned. Lily never took the mantle and moved in with a foster family–the one where Hinamori had apparently grown up in. And the hitman knew that they didn't know about the Arcobaleno's connection to the Vongola, not even Reborn's current allegiance. So it was part-disconcerting and part-aggravating.

After he had convinced the boy to join the family, he would have a very long talk about Hinamori's history when Reborn's attention had been focused elsewhere.

He wasn't guilty when he had admitted that he really didn't have the time babysitting a brat–especially when his work had been at its darkest hour of danger. But he had made an effort of keeping an eye on him through his contacts but with someone as immersed in the mafia as Reborn, it was hard to concentrate on one thing for too long. So he would freely admit that he had somewhat neglected that part of his duty without remorse.

"I didn't know Hibari-san had any brothers!" Yamamoto suddenly laughed lightly, even though his eyes were still distracted.

"I didn't know he had any relatives," Gokudera grumbled under his breath and somehow managing to imply that he questioned who would want to be–Hibari Kyoya was an insane and sadistic bastard, he had firsthand experience to even support that claim.

Reborn landed on Tsuna's head with a soft thump.

"And he's my godson," He reminded with a smirk, although the title suspiciously rang hollowly.

"Does my sister know about this?" Gokudera demanded with a glare.

The hitman scoffed.

"She knows that I have a godson, just not who that godson is," He explained nonchalantly, a contemplative look on his face as the silver haired boy nodded, appeased.

"A-Anou, I don't think Hibari-san is happy about you contacting Hinamori-san," Tsuna pointed out uncertainly as he bit his lip and Reborn scoffed.

"So?" He raised an eyebrow. "He probably knows by now that his brother will eventually end up in the mafia. Not only as being the Cloud Guardian, but the Ambrosio Famiglia are rather influential in their own regards." Reborn didn't bother to mention that he, Hibari, and Hinamori knew that it would be the only way for Hinamori to truly escape the magical community, despite the green-eyed boy repeatedly being in denial.

Silence soon followed, each of the boys mulling over the fact that Hibari Kyoya cared about someone other than himself or Namimori.

And what it also meant for the Vongola.

O.o.O
