This book is also known as "Who Exactly Is Making You Do So Much for Me?" and "Sorry, You Can Put Up With Me, but This Outsider Can't."
Pairing: Gojo and Dazai. Includes characters getting picked on; the targets vary.
The Gap Between Worlds, a strange in-between place that serves as a transfer station for the underworld. It is inhabited by a kind of soul: souls with no attachments or lingering obsessions, who nevertheless can't enter the cycle of reincarnation.
Ten years passed. Many people came and went, but only two stayed the entire time.
A certain boss: "...Why can't you leave?"
A certain Six Eyes user: "...Looks like my body was left behind."
A certain boss: "? Couldn't you have died properly?"
A certain Six Eyes user: "...What about you? Why can't you leave?"
A certain boss: "...My soul's bound to something else."
A certain Six Eyes user: "? Couldn't you have done that more cleanly?"
After hurting each other for a long time, they eventually realized this couldn't go on. When the right opportunity came, they broke through the boundary. But since their original selves couldn't return to their own timelines, they stared at each other for a long while, then made a momentous decision.
Help each other out, God Helping God.
Make sure the other one can die cleanly and decisively. :)
When a certain bandage-wearing man landed in a critical moment in time, the first thing he saw was a group of people discussing the philosophical questions of monsters and human nature.
Tzz: "...?"
When a certain man in sunglasses arrived in this unfamiliar world, everything seemed wonderful, except that someone who apparently wasn't remembered by many was missing.
Wtw: "...?"
After working hard for half the day, the two tossed and turned in bed late into the night, unable to sleep. At last, they got up in a fury and cursed the other: "What's wrong with that guy?"
They couldn't stand this world for another second. Time to start over.
And so the confused boss gained a laid-back "assistant," while the proud delinquent gained a sinister "teacher."
When the two, having changed each other's deaths and resolved their fates, and now possessing all their memories, saw each other again: "...What's wrong with you?"
God Helping God! Who told you to go and do all that unnecessary stuff?!
1. 285 Dazai from Bungo Stray Dogs transmigrates into Jujutsu Kaisen; boss-era Dazai transmigrates into Jujutsu Kaisen.
2. The worlds will eventually merge.
3. Gojo and Dazai only. The story is friendly to this pairing; no promises about anything else.
Theme: Somewhere in the world, someone is always loving you in their own way
