Suzuka decides to give all the credits to her brother Yū Nagami under the pen name Chikai Towano due to her student council president position and their strict father.

Anime
An anime television series adaptation aired from October 10 to December 19, 2018 on AT-X, Tokyo MX and other channels. The series was directed by Hiroyuki Furukawa, who also adapted Gintarō's original character designs. Yūichirō Momose handled series composition, Kisuke Koizumi was the sound director, and Yashikin composed the music. The series was animated by studio NAZ and Furukawa's own newly established Magia Doraglier. The opening theme is "Secret Story" by Purely Monster. The series ran for 10 episodes.

Reception
The anime adaptation of My Sister, My Writer was panned for its subpar animation quality. Brian Ashcraft of Kotaku described the show as one of the most notable production disasters of 2018. According to the credits of episode 2, the most likely reason for the series' deteriorating animation quality was due to studio Buyu being in charge of key animation as opposed to the main NAZ and Magia Doraglier studios. Buyu is a production company that was only in charge of in-between animation and finish animation in episode 1, and the studio usually serves as a subcontractor for other companies. Additionally, multiple individual staffers were credited with key animation rather than individual companies.
