Anime Crossover: Saving Riko Amanai from the Start

My name is Su Mu, and I've obtained a redemption System that lets me transmigrate into anime worlds.

The System says that if I save those whose stories left them with regrets, I'll receive incredible rewards. Sounds pretty good.

Except...

To save Riko Amanai, I have to snatch her away right in front of Satoru Gojo and Suguru Geto?

To free Maki Zenin, do I have to turn the entire Three Great Sorcerer Families upside down in the process?

And when I go to the Paradise Faith to save Kanae Kocho, why does Shinobu Kocho end up clinging to me too, huh?!

System, are you sure this counts as redemption? This is clearly making me dance all over the faces of every story's final boss in the whole world!

And what's with that final villain, the "Story Alterer"? What the heck is that supposed to be?

Faced with these "former regrets" who refuse to leave after being saved, I can only grit my teeth and keep going.

So, my first goal is to become the "Plot Crusher" who strikes fear into the hearts of the jujutsu world!
