Thirteen is too young to gain eight years of memories that might come to pass--especially when you don't even know what to do with yourself in the present. But when the future is that bloody and dark, do you have any choice but to try to change it? He remembers the absolute agony of the doctors trying to save him, which finally sent him into blissful unconsciousness— —except he doesn’t remember any of that. Tsuna’s last memory is of putting his head down on his desk and falling asleep to the sound of the teacher’s droning, thirteen years old and tired of not understanding a word, not of being twenty-two and beloved and dying.

Their first time is messy and awkward, fumbling attempts in the dark with laughter pressed against heated skin. Tsuna doesn’t know what to do with his hands, is so nervous he can’t seem to get hard at all, and Kyoko keeps giggling so hard she accidentally kicks him in the face. They don’t fare much better the second time, or the third. They always seem a step out of beat, never quite lining up, always missing each other. Tsuna always feels like he’s going to vibrate out of his skin, like there’s something in his gut that’s trying to claw out. He keeps expecting his flames to burst out at any second. After a while he realises he’s so used to fighting his body is wired to it as soon as the adrenaline rush hits. And Kyoko is an adrenaline rush.

It's time for Bianchi to come into her own, whether she likes it or not.

Tsuna doesn't know how he dies for good, only that he still has regrets when he does. When he wakes up, he's in the body of Sawada Nana, mother of a 2 year old Tsuna, and those regrets become tenfold. He's drowning in the implications, when an Arcobaleno appears on his doorstep, and the future becomes infinite possibility.

The men in Nana's family carry a very strange curse. They swap bodies with anyone they kiss. Tsuna really wishes he'd known that before he fell onto the pretty girl with the very loud brother...

Xanxus is eight years old and desperate to find something more than a future in the slums. When he comes across a man with broken eyes and a mastery of orange flames, he thinks he’s found it.

Tsuna is not quite human, neither are his guardians. Magic and flames can have some odd interactions.

Tsuna and his guardians died in a blaze of glory. Then they woke up, slowly, one at a time, in a different world that was the same in all the ways that really mattered. Or the one where Tsuna and his guardians are reincarnated into the class below the Konoha rookie nine.

A threat to the Vongola forces the Family to scatter, and pushes Hibari and Gokudera together as they hunt for an enemy that's far more widespread and cunning than anyone gave them credit for.

Reborn is a ashamed to say he won’t notice a lot of the weirdness about to happen before he is almost powerless to stop it.

“Reborn!” He squeaks, voice caught somewhere in his throat as panic starts to set in. Coming to the swift and horrible conclusion of what his sadist tutor is going to make him do. His thoughts are proven right as Reborn begins to explain. “When searching, people tend to overlook the opposite sex. No one thinks a mafia boss will be willing to put on a dress just to escape from capture. They assume it is against their masculine pride or some such nonsense.” Reborn’s grin is practically predatory, obviously enjoying Tsuna’s discomfort. “That is why it always works if you know how to blend in correctly.” ----- aka; the fic where Tsuna goes undercover as a girl to a local festival to learn how to avoid being captured by enemies, but ends up sexually frustrating Yamamoto Takeshi who wasn't aware he had a very specific fetish.

Present Mic first spots the restaurant when it’s his turn to patrol the local neighbourhood around UA.

He fires a Dying Will Shot at the child he's been sent here to tutor by the Vongola Ninth. What he expects is for Tsunayoshi Sawada to burst into Sky Flames; he’s from Primo’s Line, after all, for all that he’s timid and Sealed. And he does, but rather than the brilliant orange ethereal Flames he was expecting they're darker and denser.

Even pretending to be a firefly turns his stomach, but he's out of money, and it's the only way. Or is it? Juudaime found him, and defended him, and with how broken they both are, maybe they can help each others' hearts heal. Love does that, he's been told.

War Sky Tsuna and Home Sky Kyouya declare war on the Vongola.

In which Sasagawa Kyouko's smile is full of knives, and Tsuna loves her for it.

In which Tsuna has some fairly inconvenient opinions, Iemitsu has been happily living in denial for years, and Reborn now somehow has to sell organised crime to a bunch of student hippie activists. He is not amused.

Tsuna is dead. Hayato decides that is Not Acceptable. And proceeds to break space time to fix it. He regrets nothing. Except for the fact that he arrives back in Italy, half a world away from his Sky. He then embarks on the epic mafia road trip from hell to find his Sky, along with three escaped lab experiments, one kidnapped mafia heir, one runaway schoolkid on a field trip to Paris, and a dog called Spot. Or the one where Hayato is incredibly Extra about everything, and no-one but Dino notices.

The thing about Tsuna’s life was that it could never just be normal.

Tsuna’s first thought when he woke up to a white hospital room and the beeping of machines was “at least I’m not in a coffin this time.” “… What?” Oh. He’d said that out loud. Reborn would’ve shot him if he’d been there.

"Reborn!" "You weren't taking your training seriously, and I decided to take a leaf out of your current favourite manga, Dame-Tsuna. You should recognise the game." "You didn't." He'd been reading Sword Art Online, and of course Reborn would think that full immersion into a video game was a fantastic idea.

In which Xanxus has been hiding that he's a Home Sky - and Tsuna's his War Sky.

Sawada Tsunayoshi is born an Omega in a world that expects nothing from his dynamic except submission. Tsuna is many things – hopeless klutz, booksmart-deficient, heir to a bloodline some people would like to keep secret – but, as it turns out, ‘submissive’ is not one of them.

The idea comes from Visconti, who has been the one stuck riding herd on his bastard daughter the majority of the time. (He's the only one strong enough to do so, and with hindsight, it had probably contributed to his Cloud suggesting this as a solution.) It makes a lot of sense; they needed the Cavallone to keep guarding their flank, and Xana was of an age with their remaining heir.

Tsuna learned young that he was not his parents priority. So he never said anything about the itch under his skin, about the way he sometimes felt his body burn from the inside or how the only time he felt calm was when blood ran like rivulets down his skin. [Or the one where Tsuna finds a family for himself and subsequently starts taking over the world (by accident)]

There was a women lying unconscious in the alley behind the café. Nana blinked down at her bemusedly, both hands wrapped tight around the neck of a heavy trash bag. When she didn’t make any sounds or move, Nana shrugged, and made her way over to the trash bin, hauling the bag up and over into it. She was still in the same spot, sitting up against a wall, by the time Nana made it back to her, so Nana crouched down, and poked her in the cheek, peering down into her pretty face curiously. Later, she admitted to herself, wouldn’t it be more of an adventure if she didn’t tell anyone, and just helped the woman out on her own? Yes, yes it would. So she grinned, and crouched down in front of the woman and carefully lifted her onto her back. --- Nana was used to living life on her own, and on her own terms. Completely alone save for the few strays she took in when she got bored. Lal Mirch was something unexpected, though, and blew her otherwise normal life to smithereens. Namimori and Sawada Iemitsu weren't much better. What was a quiet Mist user minding her own business to do? Have fun with it and run wild, of course.

Tsuna isn't a hardcore gamer, and neither is Yamamoto. But Sword Art Online is the world's first VRMMORPG; who wouldn't be excited for the official launch? ... Before the 'death game' part of it was introduced, of course. (And the chaos doesn't stop there.)

The War against Byakuran had been desperate, and the backlash against something he tried had thrown him back in time. He made a plan, but ...

In one world, the Tenth Generation escape to a world of heroes. In this reality, they flee to a world of Pokemon.

Through no fault of his own, Xanxus finds himself in another world, trapped in the body of the No. 2 Hero. At least he has some entertainment, in the form of an angry, scarred, broken son...
