Author's Note: Hey! I'm back! Here's another one-shot that may or may not be related romantically to my other RebornxTsuna oneshot Insanity :3 I just had to write this when I read the newest chapter! SPOILER ALERT! Hope you guys like it, I'm thinking of making this into a series of one-shots centered around Tsuna and Reborn :D The rating can be anywhere from K to M based on their relationship during the chapter. There may be some AU, canon, or anything! Enjoy!

Rating: K+

Warning: I took the dialogue verbatim so unless you've read chapter 387, don't read this cause it's a SPOILER! Some slight OOCness I guess, up to you.

Disclaimer: I don't own KHR or the dialogue/names in this oneshot! I just read and enojy the show/manga. I love Reborn!

Summary: This couldn't be happening. This was insane, crazy, impossible, yet here he was, standing in a dank cave that was as old as time, listening to an Arcobaleno that shouldn't exist talk about revenge and death and things Tsuna did not want to associate with Reborn.

Conviction

"If you defeat Checker Face…what will happen to us current Arcobaleno?"

Dread and fear and absolute terror welled up in Tsuna's chest, threatening to burst forth with cold anticipation and crippling nausea – even having Reborn's comforting and petrifying presence so near didn't quell the aching horror that curled in the pit of his stomach as he waited for the answer he didn't want to hear.

"You'll die."

What?

"Reborn will…die?" Tsuna croaked breathlessly, disbelief, denial, horror, incredulity and so much more lacing the three words that made him feel sick and left his mouth dry.

This couldn't be happening. This was insane, crazy, impossible, yet here he was, standing in a dank cave that was as old as time, listening to an Arcobaleno that shouldn't exist talk about revenge and death and things Tsuna did not want to associate with Reborn. This was supposed to a chance, his chance, to help the hitman that had guided him, changed him into someone reliable. Instead he was thrown into a new world of conspiracies and learned the secret of the Arcobaleno, something that was far too complicated, too old and convoluted for him to fully understand. All he knew now was that Reborn – sadistic, incredible, invincible, powerful, immovable, dependable Reborn – was going to die.

This wasn't happening. This wasn't fair. Life isn't fair, Dame-Tsuna.

More words were exchanged, but Tsuna was lost, numb, drowning in a sea of despair that hadn't come yet. Everything was muffled, distant, gone, just like how he imagined a life without his friends, his family, his tutor would be like.

Destory. Vanish. Misfortunes. Revolutions. Sacrifices.

Tsuna snapped.

"But it's weird!" And it was. That was the only way he could describe everything up until now. It was weird. It made sense, but it didn't at all. "A revenge where Reborn and the other Arcobaleno end up dying is wrong!" His voice was so resolute he surprised himself, but the blood roaring in his ears and rushing through his head didn't stop until he declared, "I can't allow it!"

And he couldn't.

They weren't just words because he not only would be mentally and emotionally scarred beyond what Reborn could ever accomplish, the way his hands shook and his legs trembled and his chest ached told him enough. He physically couldn't let Reborn die.

He could feel the tension in the cave escalate dramatically with his words and the sincere conviction behind them. Even Reborn was slightly on edge, but Tsuna's attention was drawn away from his tutor by Bermuda's mocking laughter. "Pwahaha, this is a surprise! You can't allow it?"

Tsuna couldn't tell if Reborn was amused or being reproachful when he said, "You did it big, Tsuna."

"Eh?" He didn't see the proud twinkle in his tutor's eyes.

Bermuda, with a strange tone of derisive amusement and thoughtful curiosity, asked, "And how can you not allow it, concretely?" It almost seemed like he wanted a real answer, one that didn't involve more spilled blood despite his cruel vindictiveness and frigid hatred, but Tsuna couldn't be sure, not with the weight of Reborn's stare watching him expectantly.

"W-Well…"

His nervous, uncertain demeanor – which had come back full force when he felt the weight of his words and realized just how heavy this burden was – disappeared again when Reborn prodded him with that same knowing look and mysterious smile that made him feel warm and embarrassed. A familiar confidence washed through him, and he answered, "Th-That's obvious!" He looked at Bermuda dead on with the same will and fire that convinced so many he was the reincarnation of Vongola Primo, "I won't let you win the Representative War! I'll find another way!"

I don't need...this kind of power! If you want me to inherit such mistakes...then, I...I will wipe out the Vongola!

A stifling silence followed his bold words, Reborn tilting the rim of his fedora to shadow his eyes, before Berumuda's bitter, cold voice retorted, "Don't push your luck."

The next few moments were lost in white noise for Tsuna, his eye crossing in a confused mess when Jager suddenly moved and there was pain and a loud gunshot next to his ear. His reflexes – while still below average – kept the Vindice's hand from crushing his throat until his bandaged arm retreated. Reborn was still on his shoulder, tense and irritated with Leon still transformed.

Tsuna was vaguely aware of Bermuda's false, insincere apology, concentrating on at least ignoring the pain in his shoulder, but the world fell away when Reborn declared, "I will follow Tsuna's will. The negotiations are broken off."

Warmth bloomed in Tsuna's chest at the certainty and trust in Reborn's words.

"Pwahaha. Congratulations, Reborn-kun." Bermuda sniggered derisively. "I didn't think you were so crazy about Sawada Tsunayoshi-kun." His voice darkened with disappointment and pity. "Do you think you'll be able to go back after that answer?"

A determined fire ignited in Tsuna's chest and heated, powerful, unwavering flames flared to life around him. He stared down Bermuda and Jager with dispassionate, expressive eyes, baring his soul and condemning theirs, and retorted, "Do you think we won't?"

He couldn't help but think, with Reborn by his side, they could take on the world if they had to.

Author's Note: Sorry if the ending seems a little rushed, I wanted to get this done and published as soon as I could. Sorry for any grammar/spelling errors :3 I love these two, and Bermuda was the perfect antagonist to bring out their special relationship. This oneshot is really canon-based, so no romance, but my next one-shots, hopefully, will be :D Faves and reviews are greatly appreciated
