Isn't It Inappropriate to Bring a Kid Along in a Survival Game? [Anime Crossover]

[Putting this on hold for now. Updates whenever. A crossover mainly featuring Jujutsu Kaisen, though it can also be read as an original story.]

Blurb:

Loading your escape game. Please wait...

Everyone, give it your all and do your best to escape!

In a thrilling escape game,

Toji receives a bounty notice: Gojo Satoru is worth seven billion. While everyone else is thinking about how to survive, he’s thinking about how to make money.

"Getting rich overnight is usually unrealistic, so I’ll just have to work for it."

But when he finds his target, he discovers that his seven-billion-dollar payday is a little kid who needs looking after, with soft skin and no survival skills. One wrong move, and the kid could die before they make it out.

He immediately calls the client who posted the bounty.

"Bringing a little brat into a game this dangerous? Doesn’t seem like a good idea."

"What do you want?"

"You’ll have to pay me more."

[Content warning]

No cursed energy, Stands, Hamon, or supernatural abilities. Everyone has the same combat ability. The story focuses on wits.

Anime featured: a lot of them. [Mainly Jujutsu Kaisen]

Theme: We must strive to survive and prosper. Everyone is remarkable, and those who work hard are the greatest.
