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...

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.

“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.

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.
