Villainess Level 99: I May Be the Hidden Boss but I'm Not the Demon Lord

Alicia Ehnleit, the heroine, navigates her otome RPG fairly normally, encountering her three love interests before meeting the villainess, Yumiella Dolkness. As a noble, Yumiella stands out with her dark hair and rare dark-type magic, often associated with the Demon Lord. However, Yumiella has a secret: she regained memories of her past life in modern Japan at the age of five, learning that her fate is to become the hidden boss, not the Demon Lord. Yumiella's desire for a quiet life takes a different path as she chooses to develop her magical abilities and level up in secret, but her level 99 powers are soon discovered.
