When Gokudera died, taking a bullet for Tsuna, he expected to go to hell. Not wake up as a pink haired girly-boy in a world full of ninja. How's he meant to be the Jyuudaime's right hand in a world that doesn't even have a mafia? Clearly, he'll have to clean this place up before Tsuna gets here. REINCARNATION, Gokudera-as-m!Sakura.

Sasuke Uchiha is cheerful, forever smiling, and deadly with a sword in hand. Team 7 is cohesive, capable, and formidable apart but unbeatable when together. This world is better for all of it. [OR: Takeshi and Sasuke are one and the same. Mafioso and shinobi aren't so different, after all.]

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.

In a world where Fugaku has three sons, he wishes he'd stopped at the one. There's nothing wrong with the youngest, it's just... The middle child.

In which Minato is a Sky, Obito is his Guardian, and everything gets fucked beyond measure.

When Uzumaki Naruto breathed his last, he didn’t expect to wake up in the world of the living again. He was old, and tired, and so, so ready to move on. And, well...he wanted to see his wife again, dammit. But, of course, that wasn't what happened. Why? Naruto screamed at the powers-that-loved-to-fuck-with-his-life-and-now-his-afterlife-too, with tears streaking down his cheeks, feeling cold, weak, hungry, and utterly disgusted. Because you’re everybody’s bitch, Kurama helpfully supplied.
