Premise
Keyaru, who is exploited and sexually abused repeatedly by others due to being a healing magician, notices what lays just beyond his healing magic, and is convinced that a healing magician is the strongest class in the world. However, by the time he realizes his own potential, he is already deprived of everything. Thus, using his healing magic, enhanced by the magic-enhancing properties of the Philosopher's Stone on the world itself, he goes back four years into the past, deciding to redo everything and get revenge on the ones who abused him and take down a corrupted empire.

Characters

 * Keyaru (ケヤル) Keyarga (ケヤルガ) / Keara (ケアーラ)
 * The Healing Hero and the series' main protagonist, who was blessed with the hero's insignia from the coming-of-age. He, however, wanted to save the world from demons only to endure four years of physical, mental, and sexual abuse at the hands of his own allies, making him see how corrupted the Jioral Kingdom is. In the midst of the battle with the demon lord, Eve, Keyaru managed to retain himself finding the true nature of his power and obtains the Philosopher's Stone. Instead of handing it to Flare as instructed, he uses the item to travel back in time, all while being able to maintain his memories of the original timeline, to exact revenge against his torturers and bring down Jioral. During this, he changes his appearance and renames himself Keyarga. His thirst for revenge and mostly psychopathic personality (gained for the torture he endured) makes him a villain protagonist, although he does have a caring side.

 * Flare Arlgrande Jioral (フレア・アールグランデ・ジオラル) Freia (フレイア)
 * The Magic Hero and the first princess of the Jioral Kingdom. Flare is the main source of Keyaru's suffering and merely sees him as a baggage carrier and drugs him so he would be receptive to her commands and trains him so that he can be of some use to her. Generally, she saw healing magicians as the lowest class in the magic world until Keyaru has proven otherwise and doesn't trust her with the Philosopher's Stone. In the alternate timeline, when Flare is left vulnerable, Keyaru tortures her, takes her powers, erases and alters her memories and appearance to become his companion and lover named Freia, all while deceiving everyone into thinking that Flare is dead. As Freia, she is meek, kind, and obeys Keyarga's every command, including sometimes "acting" as Flare. She is one of Keyarga's closest allies.

 * Setsuna (セツナ) Nayuta (ナユタ)
 * A female demi-human slave that Keyaru buys and recruits into his party. Prior to this, she was infected with an illness (which Keyarga helps to cure), but her rage allows her to withstand it. Setsuna comes from the Ice Wolf clan whereas estranged from humanity and usually sold into slavery that defeats the purpose of equality in the Jioral Kingdom. As Keyarga offers her the chance to avenge her tribe, she reveals her unspoken true name to receive empowering strength from Keyarga, allowing him to gain control over her. Setsuna later becomes sexually attached to Keyarga and often competes with Freia for his affections. Similar to Freia, she is also Keyarga's closest companion.

 * Eve Reese (イヴ・リース)
 * A demon who is one of the candidates to become the Demon Lord. In the previous timeline where she did become the Demon Lord and fought Keyaru in the bitter end, she tearfully begged him to spare her and granted him the Philosopher's Stone, prompting Keyaru to know what she was really trying to protect. Her objective is to kill the current Demon Lord for trying to exterminate her brethren. When she completes the trials of Caladrius, her hair changes from black to silver. In the alternate timeline, she becomes a member of Keyarga's group. Unlike the other girls, she is not entirely comfortable with having sex with Keyarga.

 * Norn Clatalissa Jioral (ノルン・クラタリッサ・ジオラル) Ellen (エレン)
 * The second princess of Jioral Kingdom, and younger sister of Flare. Both sisters had a close relationship until Flare received a higher reputation for awakening as the Magic Hero and belittles Norn. Compared to her big sister, Norn runs her kingdom in a sadistic and manipulative manner and aims to drive Flare out of the throne. Following Flare's apparent murder, Norn meant to gain aid from neighboring kingdoms by exterminating all innocent demons, after her soldiers killed a friend that Keyarga got to know. She is the first to discover that Flare is still alive and is the only person who knows this besides Keyarga. He and Freia halt her schemes and capture her. As he did with Flare, Keyarga rapes her and erases and alters Norn's memories and appearance to become his little sister named Ellen. As Ellen, she has a brother complex and views Freia as a "big sister". She is also a very close companion to Keyarga, just like Freia and Setsuna.

Her constant flirting with Keyaru makes the other girls jealous.

After Leonard murders Anna, Keyarga takes his revenge on him by turning him into a girl, having him get gang raped by his brainwashed troops, and then burning them.

Light novels
The series was first published online in December 2016 on the user-generated novel publishing website Shōsetsuka ni Narō by Rui Tsukiyo. It was later acquired by Kadokawa Shoten, who published the first volume as a light novel under their Kadokawa Sneaker Bunko imprint in July 2017.

On January 23, 2021, Tsukiyo tweeted in English, claiming that one overseas publisher refused to publish the series in English. They said that the situation may change if overseas publishers received enough requests. Tsukiyo also encouraged fans to check out the English version of their other light novel series, The World's Finest Assassin Gets Reincarnated in Another World as an Aristocrat, which is licensed by Yen Press.

Manga
A manga adaptation by Sōken Haga began serialization in Kadokawa Shoten's Young Ace Up website on October 24, 2017. Fourteen volumes have been released as of February 2024.

A spin-off manga series illustrated by Ken Nagao, titled Kaifuku Jutsushi no Omotenashi (Hospitality of Healer), was serialized in Young Ace Up from January 18, 2021, to May 23, 2022 and collected into two volumes.

Anime
An anime television series adaptation was announced by Kadokawa in November 2019. The series was animated by TNK and directed by Takuya Asaoka, with Kazuyuki Fudeyasu handling series composition, and Junji Goto designing the characters. The series aired for twelve episodes from January 13 to March 31, 2021, on AT-X, Tokyo MX, KBS, SUN, and BS11. The opening theme is "Cruel Dreams and Sleep" (残酷な夢と眠れ) performed by Minami Kuribayashi, while the ending theme is "If You Can Change the World in a Dream" (夢で世界を変えるなら) performed by ARCANA PROJECT.

There are three different versions of the anime: a censored broadcast version, a streaming-exclusive "Redo" version, and an uncensored "Complete Recovery" version. All of the stations airing the anime carried the broadcast version. In addition to airing the broadcast version at 11:30 p.m. JST, AT-X aired the "Complete Recovery" version on the same morning at 4:00 a.m. JST. The official Twitter account issued a content warning for the anime. Sentai Filmworks has licensed the anime outside Asia and German-speaking regions.

Light novel and manga
The light novel series has over 800,000 copies in print. Both the light novel and the manga grew in their popularity, which led to an increase in digital sales. Several volumes of the manga also ranked in the top ten of Amazon Japan's manga charts.

Anime
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.
