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

In the world of an Otome RPG that she played in her previous life, a college student finds herself resurrected as Eumiella, a wicked daughter of the nobility. Eumiella isn't really worth thinking about in the RPG at first, but in the endgame content, she comes back as a hidden boss with ridiculous stats that make her comparable to even the game's heroes. Eumiella's former gamer soul is rekindled after she was essentially abandoned by her parents at their family domain. She begins leveling relentlessly until, when she enrolls in the Royal Academy, she discovers that she is level 99. The heroine of the game and her love interests have suspicions that Eumiella is in fact the infamous Demon Lord, despite the fact that she had initially intended to lead a quiet and private life. These absurd powers invite a wide range of difficulties. This is the beginning of the fantasy story about a powerful, evil, and hidden boss who wishes she could just live a quiet life.
