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

In the Varschein Kingdom, black hair is stigmatized to an abnormal degree, according to an otome RPG. Eumiella Dolkness is the count's daughter, despised from birth due to her pitch-black hair—and she is also the hidden boss! Eumiella, at the age of five, recalls recollections of her previous life in Japan. Uninterested in the original game's romance, she devotes herself to mastering her uncommon dark-type magic. Eumiella has clear objectives despite this: she wants to avoid taking the stage and avoid being the unseen boss. But when she discovers that she is a level 99 student at the magic academy, it rocks the kingdom to its core. Her powers are unrivaled, and when combined with her striking black hair, she stands out like a sore thumb in both physical combat and magical dueling. Worse, the original heroine starts to believe she is the demon lord! Is the stoic aristocratic girl going to get her wish of a quiet life fulfilled?
