Kyoya was now six years old, in the first grade, and was pleased that she had kept everything mostly in character. Her interactions with everyone - mainly Tsuna - occurred with cool blunt indifference and said boy seemed cautiously content with the silence that was their constant companion. Her and Tsuna had an understanding - he didn't annoy her and she didn't hurt him and Kyoya was very pleased with their situation.

Or well, she had been until he had shown up and forced his way into their carefully maintained schedule with a grin and a laugh. And sadly she knew there wouldn't be any way in hell she could get rid of him once he was fully interested, but nevertheless she would try.

Kyoya scowled, narrowing her eyes at the green crayon in her hand and recalled the dreaded day that damn boy had came over and took a seat with her and Tsuna - the nerve of him!

And to think all they had been doing was dallying off in a corner. Kyoya had been engrossed in a book not many her physical age should be able to read and the future sky had been fiddling with some building blocks when it suddenly just happened.

Yamamoto Takeshi just up and happened.

Don't get her wrong, she liked the rain guardian just fine.

From a distance.

And from the future.

It was just that his current self was just too cheerful. Kyoya wasn't sure if the two of them had spoken as kids in canon, but as evidenced by how their high school life went, they didn't have much of a relationship.

But it really wasn't just his happy go lucky attitude that made her want to gouge out her eyes, it was the way he had absolutely no concept of personal space!

In the beginning of her acquaintanceship with Tsuna, she had fortified the no-overt-touching rule and stressed how important it was, when the boy was scared shitless it was acceptable for him to cling to her for a short amount of time but anything beyond that was a no go. And after she had scared the fluff out of the boy for daring to casually lay a hand on her a few times, he had finally gotten the message.

It had started out innocently enough, the sushi scion had come over and started talking to them as if they were already good friends and that alone should have put her on guard. So really, she only had herself to blame if she thought about it.

"Hi." He had chirped, startling poor Tsuna into knocking down his tower while Kyoya - who was conditioned not to respond in non-threatening situations - just ignored him. But sadly, her instincts had been completely wrong because Yamamoto was a danger all unto himself.

"Y-yes?" Tsuna had squeaked looking fearful as he scooted closer to her and Kyoya had rolled her eyes.

"Whatcha doing?" He asked, like he couldn't just take a look and figure it out himself and she gave a snort. That must be his famous 'obliviousness' reaching full peak and it was truly a powerful force, and it was almost strong enough to rival Nana's.

"Um… building?" Tsuna answered, scrunching his nose up slightly as he lifted one block for the new comer to inspect and Yamamoto blinked.

"Oh haha, that's cool." He laughed with a nod as he crouched down to see better and Kyoya let the silence reign for just a minute to see what he wanted but when he didn't offer up anything, she decided to cut in.

"Did you want something, herbivore?" She had questioned, setting down her book to glare unblinkingly at him and the boy started at her tone.

"Oh yeah, I do haha," He smiled, rubbing the back of his head, undeterred by her direct gaze and Kyoya had felt her eye twitch. "The teacher said we can go outside and play baseball but we need two more players to start a game."

And then without a second's hesitation, he activated his most potent hopeful stare and Kyoya had actually issued a little cackle at the sight of it. It was really too bad she was already immune to such things after witnessing her future sky's many, many faces so Yamamoto was out of luck in concerns to her.

But apparently not in concerns for the brown haired boy seated to her left. Tsuna had no such immunity and it showed in the way he had twisted up the hem of his shirt nervously against Yamamoto's stare. After a moment he had looked over to her for guidance and gave his signature 'heii!' at the expression on her face - which clearly read 'agree and die'.

Tsuna quickly returned to his blocks, shooting her frightened little glances and Kyoya felt accomplished. She was really getting good at this type of thing, it was like inspiring fear was bred in her blood. And when one looked at who her father was, it was rather obvious that it was.

Looking back at Yamamoto, she sat there deadpanning for a second because of the absurdity of her reasoning. He said he needed two players so he came and asked Tsuna and her - the most unqualified pair ever - for completely different reasons of course.

Kyoya excelled at any sport she tried - must be that innate Hibari-ism - but had already established her status as aloof. While Tsuna was not the best choice because physical fitness had a very personal vendetta it wanted to settle with him, and one did not want to get caught in the crossfire.

Looking back down at her text on "The Finer Points of Disabling a Man," as per her father's orders, she went back to ignoring him.

"We don't, uh, p-play that sport Yamamoto-san." Tsuna explained with an apologetic look and said boy looked as if the world has just ended.

"Don't play baseball?" He gasped as if the concept was foreign. "Then what do you do?"

Tsuna adopted a thoughtful look before he gave a shrug and dropped his eyes.

"Stuff." He said as he restarted his block tower and thus life had returned to normal - for a total of a few seconds.

The sound of a body plopping down next to them snatched her attention and she turned to glare daggers at the now comfortably sitting rain guardian.

Apparently, even Tsuna was confused because he turned with a furrowed brow to face the interloper.

"Um, Yamamoto-san...W-what are you doing?" Tsuna timidly inquired as he stared at the space between Kyoya and the rain idiot with trepidation.

What indeed, she thought with a snarl but like always, the boy didn't notice the dark look in her eyes.

"Since you two don't like baseball, I'll make you love it, haha!" He declared, slinging an arm around their shoulders and quickly without preamble Kyoya grabbed her tonfas and sprung. She had clocked the boy in the chest and sneered.

"Don't touch me so freely, you herbivore." She threatened him and that had been that. And it was still that and what was worse, he didn't get tired of her abuse!

He kept getting hit and kept coming back despite how she treated him! So instead of trying to run him out, she simply began to treat him like she treated Tsuna but it didn't make him any less frustrating.

Her only reprieve was the break that was starting tomorrow, thank whoever for small mercies.

Picking up her bag at the end of class, she made for the exit as quickly as she could.

"B-bye Hibari-san." The brown haired boy called with a wave and Kyoya gave him a nod but felt her brow twitch when Yamamoto echoed the sentiment.

Tossing a glare back at the boy, she practically ran out the front doors of the school.

Searching for her mother in the crowds, she was surprised to see her father waiting for her instead. There was a group of women tittering off in a corner, shooting him what they thought were 'flirtatious' and 'seductive' looks and Kyoya wanted to laugh. If he mother had been there she would have tossed her father over to the women to let them try their luck, because she already knew who Kyoya Sr. belonged to.

The Italian woman had her father wrapped around her delicate, little pinky finger.

As soon as her dad caught sight of her, he waited until she was by his side to start walking and Kyoya tilted her head to look at him.

"We're going to go visit a few friends of mine." He informed her and she wondered if these 'friends' were mafia.

"Name?"

"The Tetsuya family, be sure to be respectful." He told her. "They have proved to be a good ally to me, and thus could be the same for you."

She drew up short and faltered. She was going to meet her future prefect vice president? That boy had been canon!Hibari's right hand man, so he had to be hers as well. He most definitely was an ally she wanted and needed if she desired a loyal interface within the school.

"Hn. Of course."

She was in complete awe as she gaped at the many people crowding around. She had thought that maybe the other Hibari had made him wear his hair like that, but it seemed to be a family thing among the males. The pompadour style was very much alive outside of Spain and it made her wonder what type of hair gel they used to keep it set like that.

Trailing behind her father, she entered the main house. Watching every person they had passed bow their heads to her father, she came to realize they were aligned with Kyoya Sr. like the way some families were to the Vongola.

Which meant Tetsuya was Yakuza. She so knew it.

Entering into a room with a large group of people in it, Kyoya was greeted with the younger version of her vice president and boy did he look displeased.

"Hibari-sama, today is the day you have decided to test your heir?" The leader - Tetsuya's dad? - asked and said main inclined his head. So eloquent, her father.

"Very good, now if you and your heir would follow me we can continue as planned." He nodded, leading them through a door behind them that lead to the back yard.

Glancing at her father's impeccable poker face, she turned back to Tetsuya's dad.

"Today Hibari Kyoya's own progeny will face mine just as the two of us had done many years ago." He announced and Kyoya blinked. She was going to fight her vice president?

"And if she should lose or refuse the challenge, she revokes her rights to our clan and gives the title of Leader over to my child, as she would be proven unworthy."

She blinked again. So if she lost, she would lose Tetsuya? That couldn't be good for the future.

"Does she agree to the terms?" He concluded, addressing her directly this time.

She honestly had no choice.

"I do." She answered readying her steel bars.

"Then may both contestants enter the arena."

Entering the wide field, Kyoya looked over at the glaring boy with confusion. He seemed to hate her though he had practically loved the other Hibari. Readying herself, she slipped into her stance and watched as Tetsuya pulled on a pair of spiked brass knuckles. So his style was boxing then?

Meeting her father's gaze she saw the message written out for her.

'Don't lose or don't come home'.

Just visiting some friends, indeed.

"Hajime!" The proctor called and with that the fight began but neither made a move.

She was wary, she knew nothing about his fighting style from the manga and she wasn't sure if it was like Lussuria's Muay Thai, Ryohei's Boxing, or some rabid new, hybridized combo.

Just as Kyoya was debating whether or not to attack first, the choice was taken from her. Tetsuya rushed forward, his left fist jabbing out at a surprising speed and she nimbly dodged, blocking them against the metal of her tonfa.

Staying on the defensive, she allowed him to engage her as she tried to get a feel for his style.

He was fast, that much was certain, and fairly precise with his punches but unlike her, he wasn't fighting with a clear head. He was angry, that much was clear, probably about having to serve her and when this was over, she'd have to clear that up.

Making her move when she caught him over extending his punch, she swung and skimmed his middle. Bruising it at the most and if he hadn't maneuvered out of the way, it definitely would have been worse.

And so it continued, her dodging his hits and occasional kicks while she parried and stuck him in non-determinable places - ei: wrists and shoulders.

She admitted she had gotten confident so when he suddenly struck with a whole new level of speed, she was surprised. Only on impulse had Kyoya canted her head to the left and smacked the side of his ribs with a pleasing thwack.

Watching him withdraw and bounce subtly on the balls of his feet, she felt the warm liquid run down her face and with begrudging gleefulness' saw him wince and cringe at his own movements.

She wasn't the only one hurt and that was good.

Spinning her tonfas in her grasp, she set the longer ends to her elbows and changed her stance into a more relaxed one so flawlessly that Tetsuya looked confused.

It seemed she was going to have to put her mother's training to use, flexibility would serve her better here.

Pressing the ends of her tonfa together, they connected with a click. Shifting the handles inside of the steel tubing, she held her newly formed Bo staff in her hands. When taking lessons from her mother, they had surmised that her tonfa were not the best choice with the style she was being taught, so after some experimentation she had been given a pole to fight with.

Rushing forward, Kyoya thrust the end into the floor and vaulted herself over Tetsuya, landing with perfect precision behind him. Not expecting the acrobatics, he attempted to turn, sloppily ducking under the whizzing metal she sent overhead and he fell back. Though that wasn't the wisest of moves, since it put him into the prime position for her to double back and clip him about the ankles.

While she was slashing downward, Tetsuya managed to lock her staff into the spaces of his spikes and attempted to pull it from her grasp. Tightening her fingers, she allowed the momentum to pull her over his head.

Landing in a crouch she set the bar on her shoulder and pressed down on her end. With his spikes trapping her staff it was a battle go see whose metal could break whose, and if he knew what was best for him, he would concede.

And as she thought he gave in and the pressure on the opposite side was gone. Dashing away, she spun to face Tetsuya but now instead of the burning fury she had spied before, he held a begrudging respect and curiosity towards her.

Seeing this Kyoya disassembled her staff and reequipped her tonfas. Nodding slightly and receiving one in return, they re-engaged with a different kind of ferociousity.

The two met each other hit for hit with a vicious smile on their faces. Both fighters reached a stalemate as their weapons ground against each other but even with her excitement, she wasn't unaware of the happenings around her. He jerked his fist, making her lose her grip on her right tonfa and it clattered to the ground.

Said hand flew at her stomach just as the tips of her fingers grasped the handle of her wayward weapon.

Drops of red stained the ground as Kyoya hunched over his arm and Tetsuya stared down at her in shock.

And so, without warning, she swung her tonfa and watched with satisfaction as it connected the side of his jaw and he fell to the ground. Pulling back everyone was allowed to see her hand sitting between the spikes of the glove and the sides of her fingers were pressed against the sharpness, bleeding slightly.

Grinning, she sprung at him, bar pressing against his throat as her legs pinned his arms to his side.

"Kamikorosu."
