Itachi was a good looking troubled teenager left to wander the country unsupervised in the company of a group of insane criminals. He may have made a few questionable decisions involving alcohol and women. It is also worth noting that no-one actually got around to explaining the use of a condom to him. The results are depressingly predictable. Or the one where Itachi missed shinobi sex ed and ended up creating spawn across half the elemental nations, which Sasuke somehow ends up responsible for.

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.
