When Gojo-sensei was sealed inside the Prison Realm, the Book came to him.
The Book told him it could turn back time and send him back to the year he enrolled at Jujutsu High at fifteen, before any of it had happened.
Gojo-sensei rubbed his hands together. "That's an option?"
The Book: "There's one condition."
Gojo-sensei: "?"
The Book pulled out a Dazai.
The Book: "You have to raise this Dazai properly. Under no circumstances can you let him develop the bad habits of drowning himself, eating poisonous mushrooms, crawling into trash cans, or jumping off buildings!"
Gojo-sensei was full of confidence. "No problem. I'm an experienced man. Every kid I've raised has been happy!"
(Megumi: ...)

Boss Dazai had just leaped off a rooftop when he opened his eyes and discovered he'd turned into a baby!
A white-haired man was holding him and showering him with kisses. "Baby Dazai, your dad's future depends on you. You absolutely mustn't grow up crooked!"
What the hell? And he dares to call himself my dad?!
Boss Dazai screamed furiously, "Waaah, waaah, waaah!"
Gojo-sensei: "Aww, Baby Dazai is so cute! Let Daddy give you a kiss~ Mwah~"
Boss Dazai, with spit smeared all over his face: "..."
Damn white hair, just you wait!

Gojo-sensei was full of ambition as he set out to raise Dazai, but the baby soon taught him a lesson.
As soon as Baby Dazai learned to crawl, he scrambled up to the window on all fours.
Baby Dazai: "Bye-bye, decaying, rotten world!"
Gojo-sensei, teleporting to catch the falling baby: ...
Once Baby Dazai learned to walk, he tottered over to the river.
Baby Dazai: "Ah, look how clear this river is! Perfect for drowning myself!"
Gojo-sensei, teleporting to fish out the soaking-wet baby: ...
Gojo-sensei wondered, "Where exactly did I go wrong raising him?!"
Baby Dazai: "I won't give up!"
And so began the battle of wits between Gojo-sensei and Baby Dazai!
Note: OOC expected. Gojo and Dazai as father and son (crossed out), with a familial bond. The pairing is OdaDazai. No other pairings besides the canon ones.
Time will also be turned back in Gojo and Dazai's worlds, and other worlds will merge with them.
I'm planning to start this as my next book. If you're interested, please add it to your favorites~
