Office worker Lysandra is obsessed with the otome game Demon Butler and dreams of entering its world. After a fatal fall, she awakens as Lilith, the cruel villainess destined to be killed by the four Demon Butlers she once abused. She opens her eyes holding a whip over the injured Lyle, as Ceros and Mod storm in, their corruption levels dangerously high. The system warns her: lower their corruption levels or die. Meanwhile, in the dungeon, Yegade’s corruption level has reached 97—the first death route has begun.
