Four young noblewomen enter Barugan Imperial Academy expecting rigorous study, political scrutiny, and the usual dangers of aristocratic life. What they do not expect is to uncover a conspiracy that has been shaping magical bloodlines, corrupting history, and feeding on the very source of magic itself.

At the center of it all is Delmaria Winternacht, who has spent ten years trying to outrun a prophecy that names her a future criminal. As she, Kaia, Zelin, and Ghislaine form an unlikely friendship, their quiet after-school refuge becomes something far more dangerous: a place where secrets are compared, futures are challenged, and powerful men become dangerously devoted to women the world has already decided to call villains.

Dark academia, obsessive romance, political intrigue, forbidden magic, and a conspiracy centuries in the making collide in After School Villainess Club.
