Izumi Ōkido is a Japanese author best known as the original creator of the light novel series Rekishi ni Nokoru Akujo ni Naru zo, which translates to I’ll Become a Villainess Who Goes Down in History. Ōkido began writing the first volume of this series while still a high school student studying for university entrance exams. After experiencing difficulty with the exams, she channeled her focus into writing novels, a pursuit that ultimately led to her gaining popularity as an author. This formative experience of facing setbacks despite hard work directly influenced the thematic foundation of her debut work.

The light novel series I’ll Become a Villainess Who Goes Down in History is Ōkido’s principal creative work. The series has been adapted into multiple formats. A manga adaptation exists, with Ōkido credited as the original story writer. A 13-episode anime television adaptation premiered in the fall of 2024. Regarding adaptations, Ōkido has expressed a philosophy of deferring to the expertise of manga artists and anime directors, maintaining that as long as the core story remains intact, she is comfortable with creative changes across different versions of the work.

A recurring theme in Ōkido’s writing is a critical view of the notion that hard work always guarantees success. She has stated a belief that effort provides personal growth and clarity even when it does not yield the desired results, a perspective drawn from her own life experiences. Her protagonist, Alicia, embodies a strong-willed, hyper-focused realist, which aligns with Ōkido’s stated preference for characters with clear convictions who act decisively. She intentionally structures her stories around the clash between this realist perspective and an idealistic one, using her characters to explore the complexities of society, personal agency, and the value of effort. The author has also shared personal philosophies that inform her narrative choices, such as a belief in selflessly providing for others without fanfare.

Within the light novel and villainess genre, Ōkido’s significance lies in her subversion of standard tropes. Rather than portraying the rival heroine as a simple adversary, she crafts a nuanced ideological conflict between realism and idealism. Her work deconstructs the innocent heroine archetype by taking it to its extreme, creating a compelling dynamic where both opposing viewpoints are presented with their own merits and flaws. Her success, originating from her debut series written during her high school years, marks her as a distinctive voice within the contemporary villainess fiction boom.
