Sorcerer Rei Furuya

A Jujutsu Kaisen-style AU, meaning Jujutsu Kaisen's world with Detective Conan characters given Jujutsu Kaisen-style names. I'm trying to build up a backlog...

In short: The story of Special Grade sorcerer Rei Furuya, who accidentally winds up in a world that's purely Detective Conan.

Synopsis below

At 29, Mr. Furuya passed the Special Grade assessment this year, becoming one of the rare Special Grade sorcerers in the jujutsu world.

Encouraged by his Six Eyes underclassman, Mr. Furuya's friends got together to throw him a celebration.

Among the guests were the Six Eyes prodigy, his squinty-eyed best friend, and the orange-haired school doctor;

Kenji, a curse user who used to be their classmate, and his childhood friend Matsuda, who had become a cursed spirit because of Kenji's curse;

Officer Date, head of the joint project between the Jujutsu Headquarters and the Tokyo Metropolitan Police Department;

And the Tokyo Metropolitan Police Department's pride, his childhood friend Hiro, who worked in the First Investigation Division...

Mr. Furuya couldn't stop the celebration from happening, so he went to meet them full of anticipation.

But...

Can someone tell him

why he ended up in a desolate suburb after being ambushed by a Special Grade cursed spirit in central Tokyo? Just one look at the distance told him he was definitely going to be late.

Why could he see a towering column of dark energy rising over Tokyo from here? Was the city under siege by cursed spirits?

Why did a murder happen as soon as he ducked into a random cafe, with everyone around him casually calling the police, who then put him on the shortlist of three suspects?

Just then, someone tugged on his coat. A little boy with black glasses and blue eyes smiled sweetly and asked:

“Why are you here, Big Brother Amuro~?”

...Who is this?

P.S. (I'll add more if I think of anything.)

1. The Jujutsu Kaisen/Detective Conan world is heavily altered. Following Gojo's ideals, Furuya will efficiently deal with the old guard. The plot will be completely unrecognizable, and I'll add things as I think of them, since I've mostly forgotten the original and even looked up a lot of the worldbuilding on Baidu... It also crosses over a little with Bungo Stray Dogs, so please read with caution if that's not your thing.

2. Not sure how much of the story will take place in each world, but as the synopsis says, the early part will definitely be Detective Conan.

3. The cafe in the synopsis isn't Cafe Poirot.

4. This is self-indulgent writing, but I'm not good at it, so please bear with me orz

The idea came to me in a Shimo document on 2022.12.23. I saved it to Jinjiang on 2023.2.8. Sorry if this resembles someone else's idea...

Theme: Get back in time for the celebration!
