A/N: I'm sorry, i've been in a bad place these last few months and haven't worked up the motivation to write much.

I'm eternally grateful to hear from everyone and i laughed at the reactions to last chaper.

(And also the likes and follows, i had no idea so many people actually like reading this silly thing.)

We have the long awaited bomb boy this chapter! And swearing.

(Sometime after purchasing a building.)

The Foundation's roots were in Japan, lead by a fearsome man named Kyoya Hibari.

If one had mentioned to Hayato that he'd be working on the (somewhat dubious) righteous side of the law five years ago he would have laughed his arse off and sent the fucking loon to an insanity clinic.

Hayato Gokudera was Hibari's middle school aquaintance (for they would rather suffer a grevious wound than admit to being friends) who, after exchange in Japan, made an executive decision to return to Europe and perhaps-kind of-maybe- mend his shaky relationship with his family.

Evidently, the silver haired man was still wavering over the concept.

Far be it for Hibari to miss an opportunity, and one knockdown bitten-to-death fight later and the now eighteen year old Gokudera found himself on his merry way to the UK with a recommendation and a letter addressed to some guy who he assumed was running some branch office of the Foundation. Or something.

Who knew what was going on in Hibari's fucking head?

This somewhat familiar midget with the wide eyes and overall unassuming appearance was definitely not it.

'He's yours now.' Was literally the only thing written on the letter in the neat penmanship Tsuna instantly recognised as Kyoya's.

Peering back up at the scowling silver haired young man sitting across from him in the cafeteria, Tsuna could vaguely recall him being in the class next to his back in middle school.

"Hayato, right?" Tsuna plastered on a smile even as the scowl turned to a thunderous expression of irritation.

What the hell did Kyoya get him into now?

Reborn was heading for his next class when he spotted Tsuna walking out with a dead man dogging his footsteps.

He was older and taller but that was evidently Hayato Gokudera, Bianchi's baby brother who apparently wasn't as dead as the rest of the underworld thought.

He was also an explosions specialist, last Reborn heard, following the only spontaneously combustible human Reborn knew.

Fuck.

Hayato wasn't expecting to have a nice day, what with meeting a guy who fucking Hibari introduced. He actually expected some violence at some point another, given Hibari's stellar record.

Which was why the sight of the greatest hitman to ever grace the underworld making for him like some fucking bat out of hell had him reaching for dynamites faster than the certified genius could think.

And Tsuna, poor Tsuna who had never outgrown his propensity to set shit on fire when startled -and it was rather startling to see entire handfuls of bombs just appear out of freaking nowhere- did just that.

Of course, he didn't set fire to the bombs in Hayato's hands, he did have some control. Unfortunately the next flammable object in the proverbial list was every other bomb in the bomber man's arsenal.

Hayato swore and dropped a veritable army's worth of explosives from among his clothes as he felt their wicks light. Paling at the sight of his lit arsenal.

Reborn sped up to shove Tsuna to the ground because if he was going to die he may as well die dramatically.

Fortunately, no one died. Mostly because the explosion that had been about to consume them had been crystallised into some morbid sculpture of explosive flame ice.

Hayato gaped from his place on the floor, one eye millimetres from a sharp jutting piece of ice. Mind working miles a minute as he replayed what happened, because he was certain he'd been pushed. And the only one close enough to push him had been-

His eyes focused beyond the ice in his face. There was shrapnel from the casings on his dynamites, and bright spots like fireworks trapped in time, and among them was the shocked face of the short guy leaning forward in a way that would have been physically impossible, had he not been trapped in ice, hands outstretched as if reaching for Hayato. On his neck was the hand of the hitman, the rest of him was outside the ice blast, and while it was hard to see through the distortions in the ice, Hayato could just make out Reborn's wide eyed expression and his mouth moving.

"What the fuck Tsuna."

Reborn startled as warmth flooded into him, feather light against his heart and cosy as a worn duvet. It had been a very long time since he felt something like this, and he felt particularly stupid for not realising as he caught Tsuna's amber eyes in the ice. Ice that was very much like the one Xanxus had been trapped in years ago.

How different was Tsuna's weird fire powers from Flames? Were they fundamentally the same thing?

"H-how?" Hayato stammered, looking like he wasn't sure if he was supposed to panic because this guy just saved him at the cost of trapping himself, or prostrate himself because the world's greatest hitman was staring at him in accusation. (Reborn's expression had defaulted to a blank stare in the face of his shock, but Hayato did not know that.)

A sound drew Reborn's attention to the fact that there was crack in the ice which was rapidly propagating across the surface like a demented spider's web, fragmenting his view of the brunet frozen inside. An ominous creaking sound followed until the entire thing shattered like fragile glass.

Tsuna shook off the bits of frozen flame and dynamite like a wet dog and beamed at the two dumbfounded men in front of him. "I'm good! Nothing to worry about!"

Neither one said anything.

Tsuna's expression crumpled as the silence continued, fiddling with a stray piece of starburst trapped in an ice-block awkwardly. "Uh, sorry about your dynamite?"

Another awkward silence.

"What the fuck Tsuna."

E/N: Reborn cannot believe his life choices has led him to dealing with Tsuna.

Hayato is torn between labelling Tsuna an UMA and stalking him to record everything from his eating habits to his underwear or regarding him with starstuck awe. (He does both.)

Tsuna will procure some dynamite for Hayato from somewhere and then have to awkwardly endure the silveret's tears of joy and reverence.
