"This is totally the flow of a villainess-centered downfall story!"

It seems I've been reincarnated as Koleha Nyarlathotep, a villainess and poison sorceress from a game world, the daughter of a marquess. But I'm pretty sure this world is one of those "downfall" stories where the villainess is the star!

I know all about this!!

Because I've read millions of these stories on a certain site!

I absolutely love downfall stories!

I adore watching people's faces as they're plunged into the abyss of misfortune, so I'm definitely going to make sure the heroine gets her just deserts!! Oh-ho-ho-ho!!

... Wait, this is the villainess's personality! I didn't have this kind of personality before I was reincarnated, did I?! I don't think so...?
