## 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.
