Eumiella Dolkness awakens to the memories of her past life only to realize she has been reborn as the overpowered hidden boss in her favorite otome RPG. Determined to avoid her tragic fate as a sacrificial endgame villain, she spends her childhood grinding in secret, hoping that absolute strength will guarantee her a life of solitude. However, her plan backfires spectacularly when she enters the Royal Academy and a mandatory level check exposes her maxed-out stats to a horrified student body. Labeled a potential Demon Lord by the kingdom’s suspicious prince and his party of heroes, she must navigate a minefield of social rejection and magical confrontations. While her expressionless face and terrifying dark magic make her a social pariah, Eumiella remains hilariously oblivious to how much her sheer presence disrupts the game’s carefully balanced script. Even as ancient threats loom and the world demands she play the part of a monster, Eumiella will do whatever it takes to secure the one thing her level-99 power can’t seem to buy: a normal, quiet life.
