The official website of the Oniichan wa Oshimai! (Onimai: I'm Now Your Sister!) television anime revealed a pair of additional cast and the first promotional video on Friday. The anime series adapting Nekotoufu's comedy slice of life manga will air in Winter 2023.


Shingo Fujii (Mushoku Tensei: Isekai Ittara Honki Dasu episode director) is helming the anime at Studio Bind, with Michiko Yokote (Jahy-sama wa Kujikenai!) in charge of the series composition. Ryou Imamura (Yama no Susume Third Season opening animation director) is designing the characters. Daisuke Achiwa and Alisa Okehazama (Jujutsu Kaisen) are composing the music. Egg Firm is credited for production.


Nekotoufu originally posted the manga as a doujin, also known by its short title Onimai, on Pixiv in February 2017 before Ichijinsha picked it up for physical publication in June 2018. Monthly Comic REX began serializing the manga in April 2019. The sixth volume went on sale on April 27.

Kodansha USA licensed the manga in English for digital release last June and published the fifth volume on March 22.
