Synopsis

[A crossover with Welcome to Demon School! Iruma-kun, Jujutsu Kaisen, and Detective Conan. Here's a preview for now. If you like it, please add it to your favorites to show your support! 🥳]

Orias Maimai, a second-year student at the demon school Babyls, was celebrating her promotion to Rank 5, “Black,” with confidence to spare. Then she flew through a wind barrier, and...

“Lucky” Maimai successfully gave birth to two sons fathered by a male demon named Zenin Naoya.

Maimai herself could only think: Huh?!!

Hello, is this the Demon Affairs Bureau? There's a creepy rat demon here.

After spending a year penned in by the feudal Zenin clan like a captive beast, Maimai finally couldn't take it anymore and escaped.

Two years later.

“I'm supposed to fight Sukuna?! Is that for real?!” A female demon named Maimai was ordered by that man to challenge “that” being.

The white-haired teacher wearing a black blindfold grinned and gave her a thumbs-up. “That's right!”

“Because our Maimai-chan is ‘super-duper lucky, like a top-tier student at the academy’!!!”

[Important news from Teacher Orias!]

① I've read the manga up to chapter 349. I'm still saving the later chapters, so this story will only use minor details from before chapter 349. (I couldn't help reading all of 457, and now I wish I hadn't, sob sob.)

② I'll use a few minor details from the demon world and the Iruma-kun spin-off.

③ The backstory comes from a little Iruma-kun idea I had in 2021. I revisited it and thought Maimai was adorable, so I decided to write this story. (See the column Iruma-kun's Daily Life if you're interested!)

④ This doesn't involve the Demon Hand Gang version of Iruma-kun (the Demon Hand Gang alternate universe).

⑤ Little Maimai fighting Sukuna? Huh?! For real?! (After watching the anime, who could resist adding a little magic? Otherwise, what was the point of watching it!)

That's all for now. I'll add more if I think of anything OvO
