Prologue

Byakuran remembered the first time he had seen his enemy, though of course at this time he had none. It was college freshmen year, his new friend Shoichi was showing him the ropes to which he was grateful regardless of the boredom teeming within his weary head. The campus was flooded with new arrivals touring and pushing through the crowds pointing and smiling as they started their new lives as post secondary students. It was almost pathetic how happy some of them looked, Byakuran sighed.

"Is there something wrong Byakuran-san?"
"Oh? No, not at all Sho-chan, please go on." He made his signature smile nodding at his red-headed companion, but stopped when a glimpse of a vending machine caught his sight.
"I'll be right back! Can you do me a favour and find me the supplementary papers for course work? It think they're by the office?" Shoichi hesitated for a moment then nodded.

"Yeah, I should get mine too, see you in a few?" Byakuran beamed.
"Yes~!" He sing-songed, walking towards the clump of dispensers in search of a break. He ordered a strawberry flavoured soda, glancing up as a machine beside gave a hard clunk. A young man around his age reached for it, wild auburn hair framing a pair of innocent eyes which held an intelligence Byakuran could only consider intuition. It was surprising to see someone so young appear to be so knowledgeable, like he held secrets, faced battles Byakuran had never known. He frowned slightly, intrigue swelling in his mind.

"Are you attending this year?" He slipped into a casual smile masking his curiosity. The man seemed put off guard, noticing Byakuran's presence.
"No," The brunette smiled, petite figure relaxing. A thick cobalt scarf was wrapped loosely under his chin, accentuating a warm looking coat. "I just wanted to see what it would be like." He gave a guilty smile.

"Why is that?" Byakuran inquired, realising he was a few inches taller than the other.
"I have a job offer already so there is no need for secondary schooling." The shorter shrugged half heartedly with a small smile.
"But you want to go." Byakuran observed speaking his thoughts. The younger nodded.
"It's not so bad... I have a lot of friends employed with me." Maybe... The young man thought to himself. He had just wanted to know what it would be like to be normal.
"There is not much you can do, then is there?" Byakuran placed a hand on the others shoulder with a soft smile. "I am Byakuran."
"Tsunayoshi Swada." Tsuna simpered. Byakuran caught the joy underneath his smile and grew more interested. Who was this boy who had secrets behind his eyes and such angelic features? Everything about Tsuna was alluring, down to the strength Byakuran could feel under his hand. He wanted to know this surprisingly radiant man who had decided to walk onto the campus on a whim.
"There you are no good Tsuna!" A high voice belted, a baby no more than one flipping through the air landing on Tsunayoshi's free shoulder.
"Reborn!" He exclaimed in alarm.

"Your family is waiting for you Tsuna, negotiations begin in fifteen minutes!" The child continued irritated from the brunettes shoulder.
"I told you I didn't want to become boss-" Tsuna cut himself off flicking his eyes back to Byakuran. "Sorry, looks like I have to go."
"I understand, see you around Tsunayoshi-kun?" Byakuran watched as Tsuna let out a nod.
"Yeah. I hope we meet again one day." 'Don't be like that Tsunayoshi' Byakuran felt a small tug at his heart as the fascinating man pulled away from his reluctant grasp, walking towards a car sitting by the road.

"Tenth!" A voice called out to him as Tsuna waved happily back, an air of regret brimming under his expression. Why had he chosen to perform in a career he obviously did not wish to do? Was it his friends? His family that made him? Byakuran frowned taking a sip from his soda as Tsuna got into the vehicle, his entire being glimmering with statuesque prose.

A part of Byakuran wished Tsuna wouldn't make such a face, yet the other stronger part of him didn't care much. He had his own goals, though the brunette was curiously invigorating it was doubtful he could further his plans. This was a new world after all. New faces, new plans, this was where he would gain a rise to an era of his beautiful world.

"There you are Byakuran-san," Shoichi stumbled towards him arms filled with papers.
"Sorry, Sorry~ Would you like some?" Byakuran asked tipping the can towards his dishevelled form.
"No thank you." Shoichi's eyes shone with irritation under the thin glasses.

Byakuran smirked turning to see if the car had gone. If Byakuran knew how important the brunette had been... Perhaps he would have ran after him. He didn't though, not for another six parallel worlds would he finally realise, how many times he had run into Tsuna. Subtly encountering the strange young man until finally coming across it. Or better put him.The Vongola Decimo in all his glory, standing in the Millefiore's way. Those would begin the days where Byakuran Finally had a playmate to chase amongst the worlds.
