what if: the ten year bazooka plot goes wrong?
shōichi might be a genius, and tsuna might’ve had the vongola hyper intuition, but things can go wrong.
i’m honestly not sure wtf the future arc actually was (sending middle schoolers to fight in a war??? with a megalomaniac?? why??? did nobody notice them gone for like 2 months? or a dead-like tsuna being sent back? or if he was alive-alive, an adult tsuna???) but i’m pretty sure tyl!tsuna planned his "death"? and only told two people (kyōya, and shōichi (who had to be told b/c he was needed in the plan))
but what if shōichi messed with the bazooka just a little more? found out how to work with byakuran’s multiverse power thing and the bazooka’s time-swapping aspects-
and just kind of. made it permanent. and didn’t tell anyone (because he didn’t test it. couldn't, in fear of byakuran finding out (already knew he was a traitor and messing with it). and the other byakurans don’t tell him because that altered bazooka literally manipulates space + time. the evil!byakurans either don’t exist, or it goes even more wrong with tsuna & co dying early and byakuran just easily takes over the world with no vongola lead by tsuna (or no vongola at all) and they just don’t know what made the universe different because it didn’t happen.
(but it did, if you get what i mean)
so, tsuna + friends are sent back before a war, before tsuna was forced to grow up and be vongola decimo. takeshi sees his dad again. kyōya gets namimori back as he loved it. ryōhei gets another shot to keep his sister out of the mafia (i'd imagine tyl!tsuna wouldn't feel right marrying kyōko considering his mental age?) or, at least, not in the crossfire if she has to be informed. gokudera gets to protect tsuna this time. etc etc.
verde gets called by tsuna, gets told to "hurry up with the box weapons if you don't want the world to end" (or something along those lines) and has mass panicking and planning. maybe arcobaleno meetings??
tldr; tyl!time travel gone wrong, with tsuna & co (guardians + maybe reborn, maybe not even all of his guardians) getting their heads shot back into their 14/15/16 year old bodies. trauma, probably, and a mass panic of getting to byakuran. tsuna learning how to not be a mafia boss and the kid he never got to be, still ruthless, but kind.
double tldr: time travel fix-it but worse somehow
