It was an ordinary morning. After heading out as usual and easily solving a case, the world's greatest detective got "ordinarily" lost.
But why had he gotten lost in another world? The boy, dressed in a detective outfit reminiscent of British fashion and wearing a brown beret, stared wide-eyed at a hideous monster.
With snacks in one hand and the other still poised to stuff them into his mouth, he stammered, "A mere monster! It won't defeat the great Ranpo!"
The strongest sorcerer brought home a boy he'd found during a mission. The boy kept his eyes half closed and seemed well-behaved, but the things he said always made people question reality.
So when the guy with the weird hair came to declare war on the school...
"I see, so you're trying to lure the badminton guy away, then come to the school and take Rika? That won't work, that won't work. You can't beat Yuta~ The great Ranpo has seen right through everything~"
Weird-Hair Guy: "??"
The Strongest: When did he become the badminton guy?!
When he saw someone eat Sukuna's finger...
"What are you doing? You got played so easily. You really swallowed that disgusting finger? How stupid. Well, I guess I can't blame you. You're the perfect vessel, so even if you didn't eat it this time, you'd have eaten it next time."
Everyone: "What?!"
"Why are you so surprised? Isn't it obvious at a glance?"
When the great detective recited Brain's plan like he was reading from a script, before it had even been carried out...
Everyone at the school: "..."
They often felt that their minds hadn't developed enough to keep up with him.
To deal with Brain, the former mastermind who was now an obvious boss, Weird-Hair Guy, who had been forced to stay at the school, was constantly met with pitying looks.
Could it be that he's still alive?
The persecuted Brain: "Where did this script-reading freak come from?! Go away!"
Out-of-character behavior warning. The romance comes later, the golden finger is huge, and there are no secrets in front of the world's greatest detective. The early story focuses on Jujutsu Kaisen, and it returns to Bungo Stray Dogs at the end. Happy ending, and it's very sweet overall.
The pairing is the great detective and a certain strongest sorcerer.
The timeline is before the Night Parade of a Hundred Demons.
Theme: Making up for regrets.
