Reincarnated as Yumiera Dolkness, the villainess in an RPG otome game, I, with my gamer spirit, leveled up relentlessly since childhood. By the time I entered the academy, I had reached level 99. While intending to avoid the game's storyline, my level is quickly discovered, leading the heroines to suspect me of being the Demon Lord. Even after defeating the Demon Lord, challenges remain: territorial reform, succession disputes, and the question of when I'll marry 'him'.
