The Strongest Sorcerer Became the Stepfather of the Double Black

Mainly Jujutsu Kaisen, with Bungo Stray Dogs and Detective Conan. Gojo Satoru pairing. OOC warning!

Nakahara Su was born in an ability research lab and deployed in war. She feels nothing for humanity and has no interest in human emotions.

The 'Book' found her and wanted her to help raise two children. One of them was, more or less, her younger brother.

The 'Book': He's not your only brother. You have an older one too, but he's such a machine that he has no idea how to raise kids. So you're the only choice.

Nakahara Su: ...Do I really seem good at raising children?

Looking at the two little brats before her, who had no memories and only their instincts left, Nakahara Su ultimately agreed. She took on this difficult task and began her child-rearing adventure!

The three members of this mother-and-children family arrive in a new world with no identities and no money, and have all sorts of bizarre things to deal with.

To make a better life for herself in this world, Nakahara Su soon picks up a tall, rich, handsome man!

As it happens, he's single and raising two kids, while she's single and raising two kids. They join forces, and just like that, they become a family of six!

She thinks everything is finally heading in a good direction, until one day...

Nakahara Su: What? This world has a supervillain even more despicable than the Demon?!

Hmph! Time to break the seal...

Gojo Satoru had never planned to get married.

But he ends up marrying a woman at first sight!

The strongest is the strongest at everything! Being a wonderful husband and an amazing dad should be no problem!

But... can someone tell him what's going on?

How did his gentle, beautiful, elegant, and generous wife turn into the villainous BOSS?

And where did all these white-haired, Six-Eyed kids of every age come from?!
