Chapter 1: Encounter

"Is this how it'll be.. from now on?"

The current 10th Vongola Boss sat in the original position, as from when he woken, cradlng his head. All the thoughts of traveling through the time and space rushing back in forth causing a migraine. Was that even possible? To be able to reverse time—to which he already experienced the future.

Heaving a frustrated sigh, he removed his hands then search his pockets. Relief washed over having to find his mittens, his Vongola ring, and HDWM pills—which he surely will need; though he could control his flames and transform it at will and with ease.

Standing from his postion, he flatten his expensive suit, which had tiny particles of DNA. The droplets smeared his palms, tainting it a dark yet light crimson red. 'It seems I must have a change of clothing.' He grimaced, wiping his palms on the surface of his expensive dress pants. His cape gently flowed with the wind, also cooling his face of stress and heat.

"Seems as if I have to find some useful utilities until a way of reversal is found." He softly spoke, gazing at the night stars with interest.

A few steps forward caused his Hyper Intuition to go haywire. Easing his muslces into a stance, his eyes cautiously observed his surroundings; keening his ears and sight to a more aware level. 'No matter how powerful this era may be, I must keep a wary eye out.' Advising himself to be at a cautious level.

His intution suddenly died out then abruptedly skyrocketed in mere seconds, causing the individual to tense; taking a more defensive stance. The sound of a gun being loaded echoed, resounding in all directions through the trees. Half a second pasted before a beaming, bright red ball of flames grazed the leaves before reaching him at unbelievable speed.

He jumped to the side using his fast reflexes, barely dodging the imcoming object. The bullet grazed his shoulder, singing the cloth, leaving behind a gape with crisped, burnt skin. 'His retaliations are fast.' He thought with a small frown.

"Oi, you. This is private property. No trespassing." A distant voice growled out, the leaves rustling with his movements. 'Italian language, huh.' He relectantly thought.

Narrowing his eyes, he clenched his fists; readying himself for his—possibly—next incoming attacks. He decided against responsing, knowing that it would cause more than enough problems. A branch snapped, the person vending his anger on nature, showed how much patience he had.

"Answer, or die!" Venom dripped from every word, promising an unpleasent fate.

Cursing inwardly, he stood rigid, allowing his guard to increase. In a slighty deep, authoritive voice, he spoke, "Trepassing on who's property, if I may ask?"

The person sprinted through the trees at a fast rate, reaching him in a second with a blade dangerously close to slicing his throat and a gun pushed upright, tightly against his abodnem. "Answer, dammit!" The person shouted, adding more pressure.

Luminious red eyes glared into his chocolate brown eyes, intensifying by the second. A click resounded in his mind, all the memories crowded his vision. He narrowed his eyes, clicking his tongue while observing the person. 'G, Vongola's 1st Generation Storm Guardian. Right-hand man of the Vongola I, Primo, or namely Giotto.' Suppressing a sigh at the others's behavior, he calmly stated, "In honesty, I don't understand your agressive behavior. In which I also don't understand the circumstances of my wellbeing suddenly appearing your property."

The red head looked as if he wanted to lash out; as if to claw his guts out and cause him excruicating pain. He then heaved angrily, slowly recoiling his gun yet keeping his blade in place. "You'd think I'd believe anything you would say. Not a chance."

As the last word left his lips, they ingaged in weaponary battle, both using special guns of their own. The destruction in the surrounding area was more than enough to look disastourous; leaving only several spots of unharmed ground. That wasn't the only thing, the chaotic noise woken the residences of the nearby mansion.

Beunknownst to the two combatants, a swarm, or group, of equally tall figures stood on the sidelines. A thick blanket of dust filled the air caused the duo a temporary blindness. Just as the dust settled, the two were about to engage in another battle until a cold, menacing voice sliced the thickened, tensed atmosphere.

"Those who have caused a disturbance to the peace shall be arrested!" A jingle of chains soon followed after. A sound of rushed, forced air neared the duo, and in a split second, both were chained.

The right-hand man didn't take it lightly, kicking and thrashing to release himself. A bottle of profanities left the man's mouth. "You piece of shit cloud! Unleash me from this!"

"Hn." Was all he replied then kept silent, deeply observing the other hostage with a hard glare. "Who are you?" This caught the rest of the groups attentions', all sending a glare and readying into a defensive stance.

The brunet looked every person over, the pieces of the puzzle all coming together. 'The Vongola's 1st Generation Guardians.' He inwardly groaned, trying to ignoring the many stares that felt as if reading his soul. Debating whether he should reveal his name of not, he went with the latter. Couldn't do no harm, could it? Taking a breathe, he slowly said, "Sawada Tsunayoshi."

The guardians briefly glance at the other, namely Ugetsu Asari. Said man gave him a smile, replying in Japanese, "You're Japanese, are you not?"

"Hai," Tsuna gave a small smile in return, only to turn away just as quick. Asari neared the youngster, giving precise length between them both.

"Tsunayoshi," He began, putting a hand on his tense shoulders. "Would you mind giving us information as to why you are here?"

Tsuna gave the rain guardian a brief glance before sighing. "Gomenasai, Otoko-san." As quick as the wind, Tsuna released himself from the cuffs in a swift movement. This action caused the other gentlemen tense and to raise their weapons. Waving his hands in surrender, Tsuna took slow, cautious step back. He wouldn't want to get caught up in a heated battle with the 1st Generation, considering they assumed he was an assassin, or intruder.

A blonde male dressed in expensive clothing stepped forth, his guardians inching closer. Tsuna's eyes narrowed as they advanced on him, also taking his own steps back. 'Quite shocking to see the 1st Generation in flesh and blood.'

"Tsunayoshi-"

"Tsuna would do just fine."

The Primo nodded, finally deciding to settle his feet place. "Tsuna," His tone showed authoration. "Would you please kindly give us information then you could be on your way." G growled beside him, his eyes casting a distress look. "Giotto-"

Giotto silenced his right-hand man with a flick of his wrist. Tsuna watched the interaction with amusement, but suddenly feeling a brink of pain in his heart. A grinning silverette appeared in his mind. 'Gokudera...' Shaking his depressing thoughts away, he stared at the group. "As much as I'd like to stay, I must be going."

Before he could move a muscle, the green haired teen decided to voice his thoughts. "Y-y-you look similar to G-Giotto!" He shrieked, fainting on the ground due to overwhelming shock. The rest glanced at both males, their eyes widen in shock before chaos broke loose.

"WHAT!" G was the most effected out of everyone, having Asari and Knuckles try to hold him back from beating the calm 10th Vongola Boss to a pulp. Raising clutched, white fist, he shouted, "You think you can just waltz in here and disguise yourself as Giotto!"

Tsuna mere rolled his eyes, watching the group with an amused expression. "For your information G, I didn't waltz in here as easily." Despite the boy being a Japanese, he was absolutely fluent in Italian, surprising the guardians.

Noticing the blood on the others suit, Giotto asked hesitantly, "Any understandment as to why your attire is bloody?" Tsuna glanced down and a ghost of smirk appeared on his face. "Guess you could say I went through warfare."
