悪役令嬢レベル99 ～私は裏ボスですが魔王ではありません～

Yumiella Dolkness wakes up reincarnated as the throwaway villainess of an otome game she played in her past life as a hardcore gamer. Determined to avoid the heroine's path and the role of hidden final boss, she grinds monsters in seclusion until she quietly hits level 99, far past the ceiling anyone her age reaches. When that absurd power surfaces at the royal academy, the heroine Alicia Ehnleit and her suitors begin to suspect that Yumiella's dark hair and dark magic mark her as the rumored Demon Lord.
