DISCLAIMER: I do not own Katekyo Hitman Reborn.

GREETINGS: I'd like to extend my warmest gratitude to my dear readers for putting up with me this far, and to a friend for her good and honest opinions. She doesn't have an account, nor does she want to be named. But if you're reading this, thank you. Here's to you~!

WARNINGS: Adult!Reborn. Adult!Arcobaleno. AU.

SUMMARY: He was dame, someone truly not worth-recognizing. And while he bore some striking resemblances with the first Vongola king, he was just Tsuna. Simply Tsuna, born to an ordinary line of Sawadas. Or… at least that's what the family tree said so.

Prologue: Vongola Celebration

"Higher, papa!" A five-year old kid said as he sat on top of his father's shoulders. His tiny hands grab hold of what little he could of his father's short blond hair and shook it, demanding him to comply to his request. The blond man grinned at his son.

"Hai, hai," he replied, finding a sturdy wooden box nearby and using it as lever. "And higher we go!" He hoisted his son up, grabbing his hands as the other now literally stood on his shoulders. Little Tsuna's brown eyes widened in glee. His lips curved to a smile as he watched the parade on the streets.

People were cheering here and there, throwing confetti at the royal convoy. While an event like this was commonly done at least once a year, this year however was particularly special than the others, especially after all that had happened the last five years. Today was a day of celebration for the entire Vongola Kingdom, as this was the day their Prince Riku had finally recovered after that tragic incident a few years back.

That incident, now better known as the Siege of Vongola, was the first major outbreak within the kingdom after such a long time, in the capital Sky Village no less. Unknowingly, spies from the nearby Millefiore Kingdom were able to infiltrate deep within the land; and when the sudden news came the Queen was about to give birth, mayhem ensued and the enemies attacked all at once. At that time, Vongola Quinto was off to a neighbouring village, just finishing his investigation with some of his advisers. He wasn't able to get back on time. And when he did, the Queen was already dead; and his newborn son, albeit protected, suffered poor health in his early years.

Vongola Quinto wasted no time and wrecked havoc on his own after hearing the news.

It was the first time everyone saw the other side of their revered King.

If not for his advisers, more blood would've been shed.

It was a year of great mourning for each one.

After all the surviving Millefiore agents were sent back, Vongola Quinto did everything he can to reconstruct the kingdom thereafter, as well as keep his family, mainly his son, in check. He didn't retaliate further, as doing so would only make matters worse; but he did forge a contract to scare the Millefiore off, stating that if they did so much as steal a chicken, the Wrath of Vongola would finally be upon them.

Until now, the effects of war were still there. People who've lost their homes wandered aimlessly on the streets, or joined the growing number of bandits on the outskirts of the villages. And thus, with the help of his advisers, Quinto decided it best to address the internal matters first, strengthening the base of the kingdom.

And after five long years, his hard work finally paid off. In the form of his son.

The court physicians announced Prince Riku strong enough for any medication.

And thus, the celebration.

"Look, papa! Look!" Tsuna pointed at the last carriage of the convoy. Iemitsu tried his best to balance the kid, all the while trying to laugh to appease his beloved son.

At the end of the parade, pulled by majestic white horses was an open white carriage where the current King, Vongola Quinto, as well as his son, Prince Riku, and his right-hand adviser were. As proof, on both doors of the carriage was the golden insignia, the Crest of the Vongola, symbol of the kingdom.

Tsuna smiled even wider.

The King and Prince were exactly as what he had heard from stories. The King had straight blond hair, piercing blue eyes and a tattoo of the red Phoenix Wings on his forehead. Prince Riku, on the other hand, while he took the appearance of his father, his hair however was jet-black and his eyes of striking violet like his mother's. Beside them, and the only man standing, his black suit and yellow tie a contrast to the white motif, was said to be the infamous right-hand of the King, Reborn. He was leaning on one side of the carriage, hands folded and his face shadowed by his ever-present fedora hat. Not much is known about Reborn, other than he was one of the Immortal Seven, or Arcobalenos, the only known one in fact—a living evidence of the Vongola Legend.

Tsuna had turned to quiet observation when the royal carriage passed by. Standing on his father's shoulders, he was able to see the spectacle past the heads before them. Though it was a bit disappointing the King and Prince never looked at the sides, merely front; Tsuna was nonetheless [still] happy to finally see them up close and together. After all, he never had the chance of meeting either until now.

"Papa! Papa!" Tsuna called, wiggling his hands in hasty demand. He was about to tell his father what he saw when, at the last minute, he froze. He automatically turned around, towards the passing carriage. And the moment he did, his gaze was met with calculating black eyes.

A flash of recognition. Confusion. Denial. Then finally, settling with curiosity.

It all happened too quickly. But Tsuna, with eyes sharp even for a child, saw it all.

"What is it, Tsuna? Tell papa what you saw~" Iemitsu's call snapped him off of his reverie. Tsuna smiled; the recent encounter already forgotten.

"Nothing, papa!" was his mere answer.

FINAL NOTEs: At this point, the plot is unclear (as is my intention); but hopefully, in a few chapters, some light would be shed. More of the Vongola Legend will be explained later as well.

Thank you for reading. Reviews are appreciated. :D
