Even a Sword-Wielding Witch Must Save the World

[Crossover: Touken Ranbu + Bungo Stray Dogs + Detective Conan + Jujutsu Kaisen. An overwhelmingly powerful disaster-bringing female Saniwa. As usual, no CP, but there will be one-sided feelings and friendship. If this is a dealbreaker, run! OOC warning. My take on Saniwa, plot-focused, and the protagonist starts off with a brain in a containment facility.]

An invincible heroine who is already overpowered from the start.

[The heroine is based on the game and anime Touken Ranbu. The crossover includes Bungo Stray Dogs, Jujutsu Kaisen, and Detective Conan. All worlds follow an everyone-survives alternate timeline.]

Her name is Ueno Riri, codename: Lady Witch.

A former, current, and future strongest Saniwa of the Time Government.

When she led her swords to take on what was supposedly an “extremely difficult mission in another world that had already killed three Saniwa,” no one told her...

That she'd face such an utterly unbelievable disaster of a situation!!!

First, former colleagues from the Black Organization chase her in a Porsche. Then a white Mazda stays on her tail, and she even has to trade fire with the enemy alliance.

After she finally shakes them off and starts the mission, her former mafia colleagues corner her at the mission site, glaring at her with grim faces.

It's a little unsettling.

In the end, does even a high-level job like saving the world have to be done by her, the Witch?

And what about her old pals in the jujutsu world? It was bad enough that they used to want to capture her, but now they've upgraded to chains!

As the villainous factions of many worlds begin to join forces, what schemes and thrilling clashes will unfold?

The Witch says:

This world deserves a better ending!
