In an alternate universe where the kids came from a world with daemons, what's different? And what's the same?

The one in which Tsuna and his friends consciously disperse to the four winds when they reach high school, and somehow, all of Tsuna's classmates manage to fall desperately for him before the end of their first year together. And have to find some way to deal with it, since life doesn't stop just because the most unremarkable guy in their year seemed to become irresistible overnight. The most popular defense in their arsenal? Is the phrase, "Sawada Tsunayoshi? Makes. No. Sense." (Or: All Tachibana Ren had wanted was to make a place for himself, away from Iwatobi and the protective hovering of his family. Nothing could have prepared him or the rest of his class for what getting through high school alongside one Sawada Tsunayoshi would mean for them in the long run.)

It should be easy to judge a man by the shape of his soul, but Strawhat Luffy spits in the face of logic and predictability.

"She was fucking taller," Katsuki's Benio repeats, fangs out. "The fuck she was." Katsuki knows what, who his daemon is talking about. He doesn’t want to know, but he does. Benio is about eye level with Midoriya Yuina. She probably also knows what she’s talking about. Maybe the shitty fainting mini-steak on the hoof just decided to stand up properly today. Maybe Katsuki and Benio have other shit to think about, like the upcoming tournament, and other shit not to think about, like needing to be fucking saved by a fucking useless quirkless mook and his fucking fainting goat, the biggest joke of the animal kingdom bar none.

Peter knows his father wasn't human. It's just not common knowledge that his mother wasn't either.

In which Yuuri was a Clearer in SAO, and this... Changes things. (Or the one in which Yuuri decides to try gaming on a whim when he's thirteen, manages to get his hands on SAO, and has to live with its impact and fallout for the rest of his life.)
