He had died- honorably, he'd like to think, despite living as a villain and an assassin for over half a century- and that, as far as Xanxus had ever figured, would be the end of that. No heaven. No hell. Just life when you were breathing and nothingness when you stopped. Except that it didn't, quite, turn out that way. Except he came back as the son of the kindest, sometimes saddest father in the world. In both worlds. A father that he knew, without a doubt, to be his flesh and blood. All at once, Xanxus had everything he'd wanted as a child. A home. A family. Stability. And he was going to fight like hell and beat down anyone who tried to take it from him, no matter what his age. (In which Sakumo raises a son who speaks multiple languages from birth, all of them gibberish to the poor single father jounin, spits vulgarity with the same ease as he does his praise and burns with an unshakable determination to build himself a family that will not fall, no matter who or what is thrown against 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.

A what if, of a what if... What if the Vongola Tenth Generation were to be raised by Uchiha Madara and Senju Tobirama? Well, for one thing they don't even bother with pretending to be nice people. For another, Madara is born into the Hibari family. Yes. Madara. Also yes. Those Hibari.
