I Dumped Suguru Geto, Then Was Forced to Save the World

I, Ritsuka Fujimaru, Master of Chaldea, have saved the world countless times. Now I can finally retire! No more overtime for me!

It's perfectly reasonable for a savior to get a 190-centimeter-tall boyfriend with a 19-centimeter... you-know-what. But only if that boyfriend with the weird pompadour isn't constantly thinking up eight million ways to kill me.

So I promptly chose a peaceful retirement without interruptions: “Geto-kun, let's break up...”

Then, at a crowded intersection, with my ex refusing to leave me alone, I had no choice but to ask the passing delinquent Jotaro Kujo for help.

“Those monkeys sure are a nuisance...”

“Evil spirit! Ora ora ora!!!”

Oh, looks like they don't need me. The delinquent boys have a truly unique way of shouting out their friendship in the middle of the street.

But what is a vampire named Dio? And who's the King of Curses, Ryomen Sukuna? Why am I, a retired woman, back on the road to saving the world again?!

*

* Main crossover: Jujutsu Kaisen and JoJo. The main characters from both series will be put through the wringer, and the plot will be smashed to pieces by the heroine's recklessness.

* The heroine is Gudako, but the story won't touch on Nasuverse plots or timelines. Though she looks cute, she's actually a retired powerhouse with maxed-out stats!

* Everyone gets to avoid dying. When she's in a bad mood, she might drop by other series and kick a few annoying characters while she's at it (or maybe not). Series that may get a few kicks: K, Detective Conan, Demon Slayer, and others.

* Very OOC. Almost everyone will probably have a one-sided crush on the heroine.

* Her ex is Geto Suguru, a second-year student (her one and only ex-husband). He's younger than her by two years.
