The Fangs of Sawada Tsunayoshi

Twenty minutes. Twenty minutes was how long it took for the patience - which up until now everyone believed to be almost a bottomless pit - of the Tenth Vongola Boss, who was just over 20 years, go to over the top and be swallowed by a wave of irritation, thus causing him to emanate a truly deadly aura.

What happened exactly in those twenty minutes was his two most problematic Guardians grappling in a death struggle. They destroyed not only the training room in the process, but also part of the east wing of the Vongola mansion - as Tsuna observed when he marched out of his office, in that hitherto quiet morning and he entered in the other end of the mansion. He passed through the hallways without missing any of the amazed looks the frightened employees had on their faces caused by the destruction, tremors and rumbling. Clearly, these were the results of the violent attacks created by the two vicious Guardians, who were throwing one blow after another. The lithe man continued to ignore the startled looks that were directed towards him due to the unusual heavy and dangerous aura emanating from his body. His threatening presence and displeased expression made everyone wisely avoid standing in his way as he marched toward the sources of the destruction.

Tsuna was angry. Very, very angry. Angrier than anyone had ever seen. For the past twenty minutes he had been trying to ignore the growing destructive, and especially murderous intent, emanating from downstairs, in the direction of the the training room. While the battle raged on, he had been trying in vain to concentrate on the damn monstrosity embodied in paperwork, which as always, was resting defiantly on his desk.

The disagreement between the two Guardians began shortly after breakfast, in an exchange of unilateral taunts from Mukuro, and the normal threats of 'I'll bite to you death' from Hibari. It had quickly evolved into a confrontation in the room, which was now was destroyed. At first, everyone thought the two would solve their dispute instantly once and for all, since the quarrel between the ex-mayor and the illusionist had been dragged on for six years. But that thought went into space when the first tremor ran through the entire mansion. Tsuna, whose blessed Hyper Intuition had been kicking his head and piercing his stomach since he woke up, had been stubbornly ignoring the ruckus since then. This was, until a lasting tremor scattered and disorganized on the ground, two huge piles of files and reports that had kept him awake until four in the morning. Something which almost cost him a concussion in the head from a ten ton Leon-hammer possessed by his tutor Spartan, who was angry to find his student sleeping in his office again. Yes, it was after that tremor that he decided that since the two could not end their disputes, then he would.

In front of the reinforced steel door of the training room, the other Guardians, who currently were all present in the mansion, except for Lambo who was in school - were stuck on deciding on what to do. Yamamoto was training in his dojo when he felt the aura radiating from the mansion followed by violent clashes, and he decided to see what was happening. Upon entering the mansion, he was greeted by a strong quake, which soon told him where the problem was coming from. Running through the halls, he found an angry and cursing Gokudera, who was the first to reach the room, and a Ryohei shouting 'let's break down the door to the extreme' while launching a bandaged fist into the air. A pale Chrome was found standing next to the nervous Kusakabe and an anxious Fuuta. As for Reborn, Yamamoto had seen him when the swordsman made his way into the Vongola headquarters, the Hitman was simply sitting quietly on a bench, drinking coffee in the front yard. Certainly the Arcobaleno was using this dispute between the Guardians to test the reaction of his pupil, and so he didn't even bother to try to stop the fight.

It was obvious that the situation was completely out of control. Although all are certain that something must be done, no one seemed to want to take the initiative. Gokudera was clearly tempted to let them knockout each other 'for disturbing Jyuudaime' while Ryohei just wanted an excuse for an 'extreme fight'. The Guardian of the Rain, had changed his usual smile into a frown when he realized the seriousness of the problem. The man had meditated for a moment, thinking that the best option was to end the fight. However, before the baseball lover could come to a conclusion, an aura even more frightening than the one emanating from the room took over, dropping the temperature below zero degrees.

"Get out." - The man's voice, which was abnormally cold and eerily calm, sounded in the ears of everyone, causing a collective shiver down their spines.

Turning, they were met with the look of their beloved boss. He was not in Hyper Mode, as his flames were not lit, yet he seemed more intimidating beyond anything they had ever seen.

"Damn bastards." - Gokudera snarled at the sight his Jyuudaime's expression, it was something he never imagined seeing on that soft, gentle and always kind face, seeing this now meant that the Tenth was truly furious.

Without missing a second, Ryohei and Gokudera, who were the closest to the door, backed away. At the same moment, a violent kick was thrown followed by a crash, which was the sound of the door falling a good three feet away, giving way to a furious Tsuna. Inside, Hibari, using the full power of his Vongola Gear Tonfas, attacked with blows covered by Shinu Ki no Honoo of the Cloud, while Mukuro rebated each strike with his trident. The Mist continuously created all kinds of illusions that his real power was able to control - ranging from huge pillars of fire with lotus flowers shooting in all directions to sharp and lethal spears made of metal springing from nowhere. The room was full of craters, and a large hole was made through the ceiling, with pieces that were once furniture, now debris, piled next to the half-destroyed walls and fallen ceiling.

They were so engrossed in their fight that they did not realize the door being thrown away. However, once a terrifying aura spread throughout the destroyed room, they immediately diverted their attention to the newcomer. Bad choice. All they saw was a smile. A large, sickeningly sweet, ghastly smile, printed on a face where a pair of orange eyes watched them like two lambs about to be sent to the slaughterhouse - or that was what the bi-colored orbs of Mukuro, combined with the gray-blue eyes of Hibari, saw before the figure disappeared from their field of vision. A split second later, he once again appeared, but this time between the two.

A powerful and very hot hand landing on their necks, was all the two guardians were able to realize before their heads clashed violently against each other. The darkness immediately swallowed both in the ocean of unconsciousness. From the broken door, the others watched the two fighters fall to the floor with a loud bang. Tsuna took deep breaths, trying to calm his nerves as he stood between the two knocked out men. Deeper in the corridor, Reborn pulled his fedora hat to cover his face, while an out-of-place proud smile made its way to his lips. He had been there quietly watching since the frightening aura of Tsuna spread through the corridors and toward the training room. His dame-student was finally able to deal with his Guardians and without the aid of his flames.

It took a few seconds for the spectators to assimilate that their boss had just knocked out the two most violent, and problematic family members in a snap. It took a while for everyone to realize that this was the first time they had ever seen their boss, who was truly gentle, finally lose patience. Which made it clear to everyone that the Tenth Vongola really was a man to be respected above all. And as it took another couple of seconds after that for them to understand that Tsuna, even being scary, was still the same gentle boss with a warm heart and cozy look. The same boss who had been momentarily frozen in place when he saw that he knocked out his Guardians without a second's hesitation.

In the end, Tsuna let his knees buckle under his weight - which was not much. Falling down, he sat massaging his temples while a frustrated sigh escaped his lips.

Getting angry at this level is even more harmful to my body than theSpartan training from Reborn- the brunet thought, taking another deep breath.

"Jyuudaime!"

"Tsuna!"

"Sawada, that was extreme!"

"Tsuna-nii."

"Boss..."

"Sawada-san."

"Sorry everyone. I scared you." - Tsuna said with a somewhat bitter expression assuming his beautiful face.

"It's okay, Tsuna." - Yamamoto reassured, helping to raise Tsuna, while launching a reassuring smile at his friend.

"Jyuudaime did what needed to be done. Someone had to stop those two bastards before they destroyed the mansion or bett- worse get each other killed."

"Ah, Takohead is right. Who knows what would have happen with these two if it continued. Although that was an extreme struggle." - Ryohei commented, with his hand on his chin as if he were trying to imagine the possibilities.

"Tch! Go cure these two idiots, Shibafu!" - Gokudera snarled, knowing that his boss would be worried about the state of the two bastards, in return for his efforts, he received a look of appreciation from his Jyuudaime.

"Oh, you can leave Takohead! Sawada, I'll take the pineapple king and Hibari to the ward and heal them there to the extreme!" - The Extreme boxer exclaimed, throwing a fist in the air.

"I'll help you, Sasagawa-san." - informed Kusakabe, already lifting his boss, who was covered with scratches, off the ground.

"I can help take Mukuro." - warned Yamamoto, kneeling beside of the other Guardian, who had several visible bruises.

It was about two o'clock in the afternoon when a certain former mayor angrily awoke from his induced sleep. He felt his head buzzing: like a crusher, a drill and a chainsaw had resolved to have a little party and they decided to use his brain as the ballroom. Forcing his eyes to adapt again to the brightness of the white walls room, which he immediately recognized as the infirmary, since it was the only room in the entire mansion painted with that color. The aloof man took a deep breath, realizing that with the exception of his head, the other wounds on his body had disappeared. Then, he pulled the memory of what had happened. It took a few seconds for his mind to process what had put him in a situation where his pride was clearly crushed. A certain brunet, carrying a predatory aura and a ghastly smile full of teeth, smashed his head against the pineapple illusionist herbivore. The same thing was already awake, lying in bed next to his bed. The normally creepy man was looking forward with an expression close to horror, as if one of the Vendice guards had come to drag him back to Vendicare. Well, certainly the figure standing between the beds of the two, with a strangely cold expression, was not one of the terrible prison guards of the Mafia world. But his aura of hours before - he was not sure how long they were unconscious - was without a doubt higher than the level of one.

"I see you are finally awake." - The neutral tone of voice was loaded with a seriousness that was usually reserved for dealing with other Mafia bosses, it penetrated the ears of both, which, for some reason, made them assume a sitting posture in their beds.

He stared at them for a few seconds. His orbs, with the familiar orange tone prevailing over the hazel-brown, narrowed in a way that made he pretty intimidating. It was not as much as when he had entered the destroyed training room, but still, it was very threatening- not that two Guardians would admit that the look of the young boss was able to exert such power over them, the great sadistic illusionist and the most powerful Vongola Guardian. Despite, deep down they knew that their expressions, same void of any emotion, were failing miserably at hiding their thoughts in front of this person, who, at some point during their six years together, learned to read them like books.

"Hibari, you live talking about not breaking the order and disturbing the peace." - The Tenth started out, finding the gray-blue eyes of the Guardian of the Cloud - "Well, your fight not only broke the order but disturbed the peace of everyone here in the mansion, especially mine. I hope that the next time you use this argument in your favor, keep in mind that you are not immune to breaking both order and peace, and, if you want it to be valid, you yourself cannot commit such mistakes." - Hibari's eyes flashed with even more irritation at Tsuna's comment - "Mukuro, your struggle completely destroyed Chrome's bedroom and she had to be relocated to one of the guest bedrooms. I'm sure, like me, you hate to see her wounded. I know that you will not admit it, but you hold her as one of the precious members of your family, the same way as I do." - Mukuro shuddered slightly at the thought of seeing his little and sweet Chrome being wounded.

It was known that Mukuro thought of Chrome as a kind of younger sister, and had become overprotective of her over the years. After all, the two shared a similar, painful past, where those who should have loved them and protected them, deliberately abdicated these responsibilities and left them to their own luck and suffering.

"You two, I hope you learn to control your genius and start acting like adults. Otherwise, waking up in the infirmary with a sore head will certainly be the least of your problems." - The orange glow stare that both of them received from Tsuna started a chill down their spine, even if they never will admit it, their boss had learned to make sure his threats would not be taken lightly - "As punishment for ruining the training room and destroying part of the east wing of the mansion, in the time that the repairs take to get ready and finished, you two will be helping me with the paperwork."

With the mention of the task that everyone knew Tsuna hated passionately with his own soul, Mukuro visibly paled. Even his signature laugh, which spilled from his lips, seemed tense. While Hibari squirmed in his bed with a look of contempt on his face, after all, Sawada Tsunayoshi had a good reason for his actions and it was within his rights to be able to 'bite them to death' - something that, his pride will never allow him to admit. No matter if the boss had proven that he was not a herbivore, or the fact that he had a much more carnivorous bite despite being disguised with the skin of an omnivore. But that man was very much mistaken if he believed that he, Hibari Kyoya, will get stuck, for whatever number of days the reconstruction will take, in one office, in agglomeration with the pineapple-irritant, doing the damn paperwork.

"I do not give a damn about the place where you will carry out the punishment. If you want to do it in my office or your own room, to me it is irrelevant. But, just as you do not let those who break your rules go unpunished, you have to do the paperwork." - Tsuna said, as if reading the thoughts of the Cloud Guardian, and this time Kyoya couldn't help shoot a surprised look at him, which Tsuna promptly returned with a pair of stolid, unwavering orange orbs, it clear to both that the Don would not let them escape unpunished this time.

"Kufufu, it seems that we do not have much choice, Vongola." - Mukuro said, his laughter still ringing a bit forced.

"Correction. You have no choice." - the Sky retorted in a neutral tone, which was still leaking a threat, with this last comment, Tsuna walked out of the ward without sparing them a second look, while massaging his temples in an unsuccessful attempt to avoid the pain and good-census kicking his mind because he had lost his temper completely.

"Hn" - Hibari simply muttered, getting to his feet, the Cloud guardian ignored his aching head, and also left the room, while Mukuro, on the other hand, nestled back into his bed.

Sawada Tsunayoshi had finally showed that he has sharp hidden fangs.

From that day forward, whenever the two Guardians were on the verge of a fight, one sweet ghastly smile full of teeth from their boss, was all it took to make them rethink their options. After all, everyone knew that Tsuna's desk basically lives overflowing with endless damn paperwork - which the Tenth had successfully found a new use for. And of course, the fact that nobody wanted to be the target of the young boss' fury had absolutely nothing to do with it...
