Tsuna’s first thought when he woke up to a white hospital room and the beeping of machines was “at least I’m not in a coffin this time.” “… What?” Oh. He’d said that out loud. Reborn would’ve shot him if he’d been there.

Where Class 1-A finds itself in a time loop centered around their first year at UA. After getting over the usual angst, they decide that the best way to grow as heroes is by antagonizing dangerous villains for fun and amusement.

Aizawa refuses to let his Problem Child travel back in time alone, even to fix a future where All for One was the victor. They go back with a plan that's more of a list, spend a year technically missing, and become rather effective vigilantes that fix some rather serious problems. And then it's time to be found, which seems to primarily result in lots of support and many hugs. Neither Izuku or Aizawa complain very much.

Shouta’s plan had been ill-defined and desperate from the start, but he figures the important shit boiled down to, “Change as little as possible, make sure Midoriya doesn’t get himself killed, and stock up on lychee jelly pouches because that flavor got discontinued three years from now.” Keeping it simple’s always better, and he’s normally good at improvising. Somewhere along the way, he must’ve fucked up since now he has: A quirkless problem child hanging off of his every word His best friend going through a sexuality crisis thanks to said problem child’s mom His other best friend clinging to him like a security blanket Some two-bit mob boss threatening him with bouquets of daffodils To wring the number one hero’s fucking neck for not telling him anything useful before sending him decades into the past All he did was walk Izuku Midoriya home. It wasn’t meant to turn into whatever mess this is.
