Since its airing, the anime adaptation of Redo of Healer gained higher than average percentage of female viewers and Tsukiyo expressed their surprise on Twitter.In Anime News Network's Winter 2021 Preview Guide, the series was panned by most of the reviewers for its recurring "rape and revenge". The reviewers criticized the series for having a "generic" fantasy role-playing game inspired setting similar to popular isekai series and for "contrived" in-story justifications for its revenge plot.
The series garnered controversy, particularly due to its depiction of extreme violence, gratuitous amounts of sexual content, rape and slavery, most elements often being used as a plot device, especially in the first two episodes. These were aspects of the light novels that gained controversy before the anime adaptation premiered.
