『Jishou Akuyaku Reijou na Konyakusha no Kansatsu Kiroku。』Character PV：Bertia（CV. Tomita Miyu）

The focus of the story is less on the Villainess and more on the mildly yandere prince leveraging her foreknowledge, if that makes you feel any better. The novelty is that the fantasy characters have figured out that Bertia was isekaied and maneuver around her while enjoying watching her get confused.
