It was a noisy arcade, as expected of its location at a popular mall. Students milled around with their friends for some downtime after classes. Weeks ago, his wimpy student wouldn't be found within the area, but now Reborn noted with approval as Tsuna smiled and casually interacted with Gokudera and Yamamoto. It was a huge improvement from the previous Dame-Tsuna.

Well, Reborn thought as he watched Tsuna accidentally bump into one of the machines, causing it to beep loudly. Tsuna jumped, startled, and a slip of a foot caused him to fall on his backside, staring wide-eyed at the flashing-red machine. People gathered at the commotion and his student flushed, hands waving in front of him in denial that no, he didn't purposely bump the machine in attempt to make the prizes fall down. Gokudera scowled at the accusation and Reborn knew he was thinking somewhere along the line of 'how dare they accuse Juudaime of such thing?!' Meanwhile, Yamamoto smiled bemusedly, trying to defuse the situation. Reborn turned away with the slight shake of his head. They still have a long way to go.

Reborn perched in his place, disguised as a stuff toy in an area where people could try to throw balls into a container to win prizes. His eyes scanned through the rest of the arcade, leaving the three teenagers to handle their own mess. They didn't need his intervention for such little things, and if they did, they deserved whatever was going to happen to them. Maybe that would teach them an unforgettable lesson of not getting into messes that they couldn't handle.

Deciding nothing was worthy of notice, Reborn was about to bring his attention back to his student when he felt a gaze staring directly at him. Reborn made a move to trace it to its source, but the feeling was gone as quick as it came. Reborn subtly checked the arcade again but failed to find anything out of place. He knew he didn't imagine that feeling of being watched, however.

Reborn jumped from his place, shedding his disguise as he did, and landed on the counter of the stall. Another jump brought him to his student's shoulder, and the relief that flashed across Tsuna's face as he registered Reborn's presence was unmistakable. "Reb-" he started, probably hoping he would sort out the mess, but Reborn hopped off his shoulder and weaved into the crowd.

He ambled through the arcade, gaining strange looks from guys and coos from some girls. A few of the more responsible-looking adults asked if he was lost, but he waved off their concerns.

Reborn felt it as he passed the shooting section of the arcade. It was a light, almost unrecognizable dab of warmth, but when he looked down, his pacifier was shining. Reborn tipped his fedora back slightly, not yet alarmed but undoubtedly more wary now, and looked at the person he had just passed by.

It was a man with slicked black hair, age around twenty-one. There was an air around him that screamed rebellious, especially with the half-smirk lingering around the corner of his mouth. He was holding a toy gun, shooting at zombies that were going after him on the gaming screen. His eyes flicked to Reborn when he stopped, before turning his attention back to the game.

"What do you want, kid? This game's not for you."

At those words, a smirk dawned on Reborn's face. At the same time, however, he wanted to frown. Was this not the person his pacifier was reacting to? "I don't play games," Reborn said. "Not with toy guns, at least."

There was no hesitation as the man shot another zombie in the head. He had accuracy, Reborn noted with slight approval, and precision. Most people would just randomly shoot and hope to hit something. In practice, however, that was just a waste of ammunition.

"Yeah?" the man said in response, like he was humoring him.

Reborn noticed with annoyance that he still wasn't giving him his full attention. Deciding a little lesson was in order, because no one ignored the world's strongest hitman when he decided to talk to them, Reborn let out a pulse of killer intent towards him.

The reaction was instantaneous. The man whirled around with practiced speed, immediately locating the source of the killer intent and focusing on it. Reborn wasn't paying any mind to that, however, but rather to the fact that the man dropped his toy gun as he turned. It wasn't the awkward fumbling that happened accidentally when someone moved too fast. No, the dropping was deliberate and as the man made a full turn, Reborn found himself facing a L-shaped gun made from his pointer finger and thumb.

Reborn wondered absentmindedly about the man's choice as they stared down at each other. After a moment, the man straightened and dropped his hand. "Don't do shit like that without a warming," he said with a scowl as he turned back to his game - only to find that during that lapse of concentration, he had already been eaten by the zombies. 'Game over' flashed across his screen. "Fuck," the man cursed as he kicked the machine. The screen shifted to the highest score list. "I only needed one more win," he bemoaned.

At those words, Reborn shifted his gaze to the screen and found that nearly all top scores were occupied by the initial U.Y. The man's eyes followed Reborn's to the screen and the depressed look on his face melted away. "Impressive, eh?" he said with a self-satisfied smirk, confirming Reborn's suspicion that he was U.Y.

"Hm. Not bad," he replied with a mirroring smirk. The man's eyebrow twitched in annoyance and Reborn didn't bother hiding his widening smirk. He jumped up to the surface of the machine and turned towards the man. "How about a game?" he said.

A glimmer of interest appeared in the man's eyes. "Oh?" he said, glancing at Reborn with a considering look. A slight thrill went down Reborn's spine at the predatory look in the man's eyes. It was the look of someone who believed he could match the world's strongest hitman and may actually have the skills to back it up. Then, the man blinked and the look faded. Reborn held back the disappointment from his face. "Too bad you can't use these," he said, picking up the dropped toy gun that was hanging by its wire. It was larger than Reborn's cursed body.

Reborn gave the toy gun a look, before unplugging the adjacent toy gun from the machine with a precise kick. Tipping his fedora slightly to alert Leon, he had Leon transform into his usual gun with the addition of a wire connecting to the machine. Reborn looked at the man. "You were saying?" he said with a smirk.

The man looked like he didn't know whether to be impressed with Leon or annoyed at Reborn. Finally, he let out a laugh. "Nice," he said, looking pointedly at the Leon-gun. "How the hell does he do that?"

Reborn saw the opportunity, and took it. "If you win this round, I'll tell you," he bargained.

Interest flashed across the man's face, before realization dawned. "And if you win?" he asked, an amused smile on his face.

"Tell me who you are," Reborn replied promptly. The man smirked like he had known all along.

"Deal."

No other words were spoken as the man slipped one hundred yen into the slot and selected two players. A red ready? splattered onto the screen, followed by a count down from three to one. Immediately after the countdown, the two went into motion.

Four zombies appeared onto the screen, crawling towards them in their undead manner. Reborn swiftly shot all four of them but found two of them shot before he had gotten to them. Reborn's eyes turned to meet the man's as the kill count went up to two for both of them. A smirk simultaneously curved both their faces, before they turned towards the screen again.

The man was better than Reborn had previously thought, but Reborn wasn't the world's strongest hitman for nothing. By the time a crowd had gathered around them because of the kills they were racking up, their screen was mobbed by zombies running towards them at a speed that ought to be illegal because it was obvious that by then, the level of difficulty was impossible and the sole point of it was to make the players lose.

By the time the game finally ended, Reborn had 324 kills while the other man had 285, and the man had that much only because he decided to ditch accuracy and randomly shot because at that point, every bullet would have gotten something.

The man let out a sigh as he dropped the gun and the screen flashed 'game over'. The crowd surrounding them let out whoops and shouts, yelling out compliments for both players and Reborn watched as the man quirked a small grin and bowed. The crowd went wild, and after a few words and laughter, the crowd dispersed.

Reborn leveled his gaze at him when the man finally turned to face him. "So," he said, shoving his hands into his pocket. "Nice game," he said with a grin that made him looked three years younger.

It was impossible for him not to smile back as he tilted his fedora down to hid his eye. "Hmm," Reborn said. He looked up after a moment. "Your answer?"

The man shrugged, not bothering to play dumb. "A deal's a deal." He took out his hand and extended it towards Reborn. "Urameshi Yusuke," he introduced with a smile. "Nice to meetcha."

Reborn was startled to find the name oddly familiar. He had heard it before and granted, it must not have been important if Reborn can't recall clearly, but it made him wary nonetheless. There was no reason why the world's strongest hitman, who was deep in mafia business, would have heard of an ordinary man's name. Even if he was uncannily skill with a gun and evoked a response from Reborn's pacifier and... the image of the man, Urameshi, pointing his finger-formed gun at him came into his mind.

"Reborn," Reborn introduced himself, letting his hand meet the man's in a handshake. In the corner of his mind, Reborn noted how Urameshi didn't simply dismiss him because he was in a child's form. Why? Reborn watched the man for any particular reaction to his name. There was none. "Do you want to join the mafia?" he asked, half-genuinely recruiting and half-curious to see a reaction.

A half-smirk curled Urameshi's lips. "I find it surprising that you don't know I'm technically already in, Arcobaleno."

In a blink of an eye, Reborn had his Leon-gun pointed at Urameshi. Then, Tsuna and his Guardians' voices drifted to his ears, and Reborn's gaze flashed towards them for a second, checking for their safety. By the time Reborn recalled Urameshi and looked back, Urameshi disappeared as though he was never there.

I love crossovers. So, I have this vague idea of how to link the YYH and the KHR world together, but I have no plot as of yet. Feel free to drop any suggestions/requests, although I can't guarantee that I'll actually write it.
