The hero who saved the world has been reborn.
In a world built from the blueprint of a female-oriented power fantasy, she is reincarnated as a princess, but she is not the protagonist. She is the villainess who ruins the protagonist's romance.
Ignis wants to change her doomed ending, so she starts changing her villainess image and tries to help the hero and heroine get together as soon as possible.
But she never imagined that the plot she knew was only the prequel.
A reader who was utterly in awe of Ignis after finishing the novel's sequel transmigrates into the heroine. At this very moment, there is only one thing she wants to do.
Dump the hero, protect Ignis from being mistreated, and conquer her!
