I'm the Villainess, So I'm Taming the Final Boss (悪役令嬢なのでラスボスを飼ってみました, Akuyaku Reijō Nanode Rasubosu o Katte Mimashita) is a Japanese light novel series written by Sarasa Nagase and illustrated by Mai Murasaki.

The series by Sarasa Nagase began serialization online on the user-generated novel publishing website Shōsetsuka ni Narō in May 2017.

[1] It was later revealed to be a television series produced by Maho Film and directed by Kumiko Habara, with scripts written by Kenta Ihara, and character designs handled by Momoko Makiuchi, Eri Kojima, and Yūko Ōba.

[41] Rebecca Silverman of Anime News Network said of the first volume of the light novel: "It isn't wholly innovative, but Aileen's growing awareness that she's actively rewriting the plot is good, and the novel just gets better as it goes on."

She praised the illustrations and said that "Aileen's active script-flipping gives the book a real edge", but criticized its use of familiar story beats and present tense narration.
