Hello, my fellow Readers I came across a challenge while looking for stories on the subject of it myself and I just kind of went 'eh, what the hell, why not'.

Here's the Challenge:

~o~

Fandom: Katekyo Hitman Reborn!

The Main Character: Sawada Tsunayoshi

Rating: ... the higher, the better :P

Genre: It's up to you.

Summary: What if hyper intuition also meant hypersensivity to external stimuli? Such as touch, hearing, smell, taste and so on? Then we have our lovely little Tsuna, burdened with hypersensivity since birth, who manages to survive in this loud and smelly world by dulling not only his senses but also reflexes and brain functions. And then, there comes Reborn, who wants to train Tsuna to be the mafia boss - obviously he'll soon notice that there is something abnormal going on with his student and will try to make it into useful skill. What happens next is up to you. I really want for one chapter, or maybe only part of first chapter, to be "the look in the Tsuna's past" to show how he manages to live with his ailment. Also: more chapters mean more delightful reading for me, so I hope for the multichapter story - as long as possible :3

Note: I have found very very similar story on AO3, but it had only one chapter and I felt that the topic wasn't explored enough. If you have any further questions don't be shy and just ask. Let the games begin!

After reading that, this spilled out of my head. So. Enjoy my brain-leavings.

~O~O~O~

Tsuna was going through his, sadly, daily paperwork when Reborn - who was about 15 years old, gangly-limbed and promising a fair bit of height by it that Tsuna had already seen, and also kept a bit quiet these days, not out of any shyness or actual reserve, but because his voice was cracking, which Tsuna secretly found hilarious - came striding in. This was, really, an unremarkable event. While Reborn was true to his feline nature, coming and going as he pleased and anyone who tried to say otherwise saw the other end of his guns, his visits were sporadic, no pattern. Tsuna didn't think it was spottiness of thought any more than anyone else did; it was habit for the World's Greatest Hitman, who likely didn't even realize he was doing it. None of which was anything of note.

No, the thing to note was something very few, if anyone, would be able to discern from the stoic hitman. Something Tsuna could see only because of his Hyper Intuition.

Now, most people thought that it just enhanced his reflexes. To a degree, they were right. Even Reborn himself thought it merely enhanced all his senses to a truly stupid degree. And, while not wrong, they weren't exactly right, either. What it did was simple; take all external stimuli and, quite simply, connect the dots. Using Reborn as an example; his walk was slow but unhurried, no sweat on his skin, not even a hint, his clothes were unrumpled, he did not smell of more gunpowder and blood than usual, more coffee scent than usual. However, the set of his shoulders was slightly defensive, his cheeks were so lightly flushed it almost wasn't there, his muscles were all tense and he was one poke away from snapping and metaphorically scratching at someones face. Clearly, something had happened to rattle the hitman, but it wasn't life-threatening or important enough to be worried about. Something had merely startled him rather badly and his metaphorical fur had been rubbed the wrong way.

None of which showed in his expression or at all, to ordinary eyes. If not for Hyper Intuition, Tsuna wouldn't have caught it either. However, he did have it, and because he did, and because he'd heard about it in mutters around the mansion for the last month and a half, he figured he knew what had surprised the not-boy enough that it showed, ever so slightly. Which is why Tsuna also felt safe in teasing his mentor about it.

"So, Colonello finally kissed you, huh?" The smoldering glare and bullets - that very carefully didn't hit the evil, evil paperwork, purposefully done by the evil, evil not-boy, Tsuna noticed - were entirely worth it for the supernova blush that beautifully lit up the ex-Arcobaleno's face. Now if only he could get Reborn to set the damn paperwork on fire . . .

~O~O~O~

Did you like it? Did you NOT like it? Has it inspired anyone to continue on this topic, which is woefully underfed? Please, even if you haven't adopted the bunny, show or pass on word about it. There is, as far as I can find, literally only one other story on the topic of Hyper Intuition, on AO3, called 'and pins scream as they fall to the floor' that elaborates on HI. That, and this, and that's it. C'mon, it's a curious enough thing to be delved into.

Also, ignore the bit of yaoi at the end there. It isn't a concrete, be-all-end-all paring. I just pictured Reborn flustered for some reason, Tsuna picking up on it, knowing why because it's been talked about around the Vongola mansion, he felt like teasing him about it, and Collonelo laying one on Reborn popped in to my head and refused to leave, so there it stayed. Somehow, it just seemed to work . . . can't figure out why.

I did add a word here and there from my original post in the challenge area, a comma here, swap a word there. Just little touch ups that, looking back over it, bothered me.

Review, review, review. And pass word of the bunny on. This is a bunny that ought to be adopted.
