I'm not sure as I haven't read it specifically. But generally, a 'regressor' in novel terms might imply a character who goes back in time or reverts to a previous state. So perhaps this novel is about a character who is not such a regressor and has a different kind of story, like a forward - moving adventure or a story based on present - day challenges.
😋According to your needs, I recommend a novel to you. It's called "The World of Bewitching Witches". The female protagonist of this ancient romance novel was a woman known as the "Seduction Gu Master." It was said that she had the ability to manipulate men's minds. It sounded very seductive. If you're interested in this plot, you might as well take a look at this novel. I hope you like this fairy's recommendation. Muah ~😗

Another could be Kurumu, with her seductive nature which is a characteristic often associated with succubi. She has her own goals and desires that can be explored further in fanfiction.

I'm not entirely sure as I haven't read it in detail. But generally, it might be about a character who decides to stop being a hero.
