AN: So… in the end I updated this fic. Huh, let's see how long it lasts.

I spent some time actually debating whether to include Personas in this fic, and ultimately I decided to… not include them. As fun as having a Tsuna who can curbstomp everyone on his path with overpowered Megidolaons and unfair Fire/Phys resistances, it's better that he curbstomps them – while following KHR rules that is.

So yes, ultimately, the result would be a Tsuna with only Yu's memories. Plus some cosmetic changes. Or are they really purely cosmetic after all?

Disclaimer: I don't own Persona 4 or Katekyo Hitman Reborn. I don't really want to be hunted down by either mafia or the I.T. because I made their life difficult.

Re-louge: World

Kurokawa Hana didn't know what to think of Sawada Tsunayoshi. Or at least as he was now, because at least before she could say truthfully that he was a no-good monkey, with particularly gravity-defying hair and doe-eyes.

When she had heard of the incident that happened to him however, causing him to take a few weeks stay in the hospital, she was torn between apologizing to him and acting indifferent at the entire matter before deciding to wait for his reaction before she could choose her own.

She hadn't expected it to happen so dramatically.

Wide eyes before that used to twinkle in a sort of innocence that she never really cared about before, turned into sharp, narrowed, knowing eyes that still carried no malice, but instead filled with a sort of weariness. His hair remained the same though, but ultimately it was only a small trifle of a detail to keep when you took the moment to stare at those irises of his.

What previously were chocolate-brown, a color that was more fit for a girl than anyone else, became the color of dark burnished orange, almost bronze, with a glint of pure greyish-silver near his pupils. They were further emphasized by the new calm air around the teen, almost perceptible as cool steel in its subtle, but undeniable, intensity.

When he had opened those eyes to the front of the class when he was welcomed, or more actually unsubtly insulted, by Nezu to completely explain his situation – as if anybody didn't know of it as of yet, plus one shouldn't have spoke little of such trauma – shouts had been the response. The more stupid monkeys actually rose from their seat and yelled at the surprisingly calm teen to explain why he was trying to be cool, Dame-Tsuna?

The reply was actually with a quite soft, and more importantly unaffected by the jeers, voice that slipped out of his thinned lips that were almost a mockery of the rare smiles she had seen before.

"I'm sorry, but I can't actually explain. Even the doctors didn't know what happened, only that for some reason my eyes have permanently changed into this color. And if I actually knew why, why would you think I would like to remember what may have caused such a drastic change to them?"

Silence reigned as everyone weighed those words. Images of the possibilities of chemicals, burned into his eyes by bullies flashed in Hana's eyes, and she found herself shaking her head and glaring down the offending monkey of a boy.

Kyoko, the kind emphatic girl she was, posed her question worriedly. "Ah, Sawada-san, would your vision be alright then?"

A nod was the response. "Thankfully, it seems that the effects are purely cosmetic. You all may simply think that it's just contacts; I won't mind."

And with that, the 'explanation' forgotten with the subject of his eyes, Sawada Tsunayoshi calmly and silently walked back to his seat. For some reason, Hana found herself holding back a growl at the sudden realization that his desk was covered with scribbles and graffiti, all of it not complimentary in the slightest. But the brunet only took to it with a single glance, before blinking his eyes once and turning to seat himself properly.

At that moment, a strange glint of resolve passed in his eyes. She would only realize what it actually meant later.

Sawada Tsunayoshi, or more exactly, the fleeting image of Narukami Yu left inside him, knew that he had to change his situation.

It was kind of strange and confusing, waking up and remembering memories that were not yours and in the same time were, and he even took the time to think who exactly he was back then at the hospital. Ultimately, with the sort of calm acceptance Narukami Yu was known for back in his world, he had decided that he was now Sawada Tsunayoshi, a middle-schooler with a sad history of having little friends and few achievements to match, only having an admittedly air-headed kind woman as a mother and only companion.

Not that he would ever say it now about her, for Sawada Nana had started to become quite a strong-willed woman, and she would've even decided to leave Namimori altogether if it weren't for his convincing.

However, as much as he had accepted that history, he wasn't going to let it stay the same anymore. His situation, as Sawada Tsunayoshi, was almost similar to his past before he arrived in Inaba, only worse because at least Narukami Yu had his outstanding accomplishments and abilities to stave off the worst of people; the kind that played with the wills of others lesser than them.

To think that Sawada Tsunayoshi- no, he had even smiled back then, even if rarely, it ultimately made him even stronger than the former leader of the Investigation Team.

His first steps were actually quite slow, but Yu was anything but impatient. The first moment that Nana had asked him for what he wanted her to get him, he had asked for some of his schoolbooks, explaining that he wanted to move on from his past failings. It caused her to fall into tears again; apologies falling out of her lips before he gave her the tightest hug his weak arms could give, whispering that it was his decision to change, not hers, before wiping away the beads of moisture from her eyes.

She had promised then too, that she would accompany him on this journey, to change beside him and develop into a better person.

Both Narukami Yu and Sawada Tsunayoshi wept their own tears from her willful statement, for while one never had a loving mother before, the other had almost wished that she didn't have to. But ultimately, both of them agreed that it was for the best. Ultimately, Sawada Tsunayoshi accepted that this was for the best.

Soon enough, his previous memories of another life as a school valedictorian for more than ten years, of a life in another world, proved to be true as he simply read through the books without difficulty. No new knowledge was actually learned, but at least he both had viable reason to explain away his newfound intelligence and proof that he, as Narukami Yu, was reincarnated in another world different from his previous life.

There were both simple and complicated changes, from the most minor differences in history of Japan to the lack of certain companies like the Junes to the very existence of Inaba.

He had taken more than an hour trying to find his beloved town in all the maps he could get his hands on, but to no avail. In this world, Inaba never had and never would exist, only a single landfill site in its place on the map of Japan. So did his previous friends, from Yosuke, to Chie, to Yukiko, Kanji, Teddie, and Naoto, to every single person that he had talked to on that year that forever changed his view of the world. Nothing in the net could ever give even the slightest information on them.

It wasn't that he had planned on talking to their counterparts like they were old friends, even if he was an old friend from another world, but cold proof that they were never even born felt like painful stabs at his heart.

It took him days before he could finally show his eyes to Nana without having to worry about the traces of his tears being noticed.

But then, he had resolved to live as Sawada Tsunayoshi, and ensure that he would find his own friends, his own companions and almost-family.

AN: Short chapter again, but in the first place this chapter is only my response and proof that I would continue this story. It also felt like I couldn't write more of this chapter before crying myself. Why did I have to hurt Yu so much again? For someone who hates angst, I'm finding myself surprisingly good at writing an outline that has lots of it…

Oh yeah, how exactly Yu died would be revealed in future chapters. It would actually be a continuation of the Good Epilogue, with a less good and more tragic ending after the game ending. I just know I won't like writing it. I hate hurting my characters after all, even for the sake of my plot. "Throw stones at your characters, tie them up and throw stones at them, even if it breaks your little scribbler's heart" eh?

On the KHR side, it would also be an AU from canon, so don't expect things to stay the same, mostly. For one, Reborn wouldn't ever become Tsuna's tutor. Think of that. None of the standard first meetings that happened in KHR between Tsuna and the rest of the gang (Yamamoto almost committing suicide, Ryohei challenging him to a boxing match, Haru beating him up with a hockey stick, Gokudera fan-boying after him after he was pulled away from his bombs etc.) also won't happen. But they would all meet, yes. After all, what is a Tsuna without the rest of his friends?

Having a bunch of OCs as main characters would be also in bad taste after all.

Next one would come in a week or two, and would be much longer, probably 7K or more. Please leave your reviews behind though, especially about my decision to not include Personas. I'd like to know your opinions, and while favs and follows are nice, ultimately I won't be entirely sure what exactly you guys like and hate unless you leave reviews.
