Akuyaku Reijou Level 99: Watashi wa Ura-Boss desu ga Maou dewa Arimasen

After being reborn into the role of Yumiella Dolkness, a notorious villainess in an Otome RPG, a former college student regains her past life's memories and realizes her destiny as the game's hidden boss. Unwilling to follow the path laid out for her, Yumiella opts to cultivate her dark-type magic in solitude, aiming to avoid the fate of becoming a feared antagonist. Her plans take an unexpected turn when she inadvertently levels up to 99, revealing her immense power during the Royal Academy's assessment, thereby sparking fears that she might be the legendary Demon Lord.

Caught in the crossfire of her own power and the game's narrative, Yumiella struggles to maintain her anonymity while dealing with the implications of her newfound strength. Her attempts at a peaceful life are complicated by the royal family's requests for aid and the suspicious eyes of her fellow students. Amidst these challenges, Yumiella must navigate the delicate balance of proving her might without confirming the suspicions that she is the game's ultimate villain. Her journey becomes a delicate dance of power and perception as she tries to redefine her role in a world that expects her to be a monster.
