Demon Slayer: Kimetsu no Yaiba (TV series)

• 1. Introduction

  ›

  Demon Slayer: Kimetsu no Yaiba premiered on the 6th of April, 2019. Within a year, it had displaced real people from the top of a children's admiration survey. A 2020 Benesse poll asked 7,661 Japanese schoolchildren who they most admired. Tanjiro Kamado, a fictional teenage demon slayer, ranked first. The children's own mothers placed second. Their fathers came fourth. Teachers came fifth. The remaining spots in the top ten went to other characters from the same series.

  A Japanese anime produced by studio Ufotable had, in under twelve months, colonized the imagination of a generation. How did a story about a boy hunting monsters in Taishō era Japan become the highest-grossing film of 2020? What made its fights feel unlike anything else on screen? And why did the creator of Gundam describe the show's success as coincidence rather than design?

  The answers begin in June 2018, when Weekly Shōnen Jump announced that the manga by Koyoharu Gotouge would receive an anime adaptation.

• 2. Building the Adaptation

  ›

  Haruo Sotozaki directed the anime, with Hikaru Kondo producing and Akira Matsushima designing the characters. The first season concluded on the 28th of September, 2019, after 26 episodes on Tokyo MX. Before the series even reached television, Aniplex of America screened the first five compiled episodes at the Aratani Theatre in Los Angeles. That screening took place on the 31st of March, 2019.

  Series producer Yuma Takahashi later cited three main factors for the show's success. The first was the quality of Koyoharu Gotouge's original manga. The second was what Takahashi called 'the attitude towards adapting it to anime.' The third was what he described simply as 'the environment.' He stressed that many viewers first encountered the manga through the anime, but that this path alone could not generate a hit.

  The staff at Ufotable approached the source material without trying to dilute its appeal. Takahashi observed that shifting trends in streaming had given shows a new way to grow their audiences. By airing the series for two cours, the show had time to find its footing. Takahashi described the growth in his own words: 'I feel that it steadily picked up fans and expanded its audience.' When the second season launched, it aired on 30 stations across Japan.

• 3. Music and Voice

  Yuki Kajiura and Go Shiina composed the score for the anime. For the first season, the singer Lisa performed the opening theme. That song, 'Gurenge,' won the Billboard Japan Hot 100 and collected a series of major music awards. At the 62nd Japan Record Awards, 'Homura,' the theme associated with the Mugen Train film, took the Grand Prix.

  For the Entertainment District arc, Aimer performed both the opening and ending themes. Man with a Mission and Milet handled those roles for the Swordsmith Village arc. My First Story and Hyde performed for the Hashira Training arc. Go Shiina's contributions extended beyond the title sequences. He composed a piece featuring vocalist Nami Nakagawa that closed the 19th episode of the first season. The same collaboration returned for the finale of the Swordsmith Village arc.

  By the 41st JASRAC Awards, Aimer's 'Zankyō Sanka' from the Entertainment District arc had won a Gold Award, following in the footsteps of 'Gurenge' at the 39th. The anime treated each arc as an occasion for a distinct musical identity rather than a consistent signature sound. At the 9th Crunchyroll Anime Awards in 2025, Kajiura and Shiina took Best Score for the Hashira Training arc.

• 4. The Mugen Train Film

  ›

  Demon Slayer: Kimetsu no Yaiba - The Movie: Mugen Train was released in Japan on the 16th of October, 2020, distributed by Aniplex and Toho. The film directly continued the television series, covering the events of the Mugen Train arc with the same production staff and cast. It broke multiple box office records, including recognition as the highest-grossing Japanese film and the highest-grossing anime film of all time.

  On the 22nd of June, 2021, the film reached audiences worldwide through digital release. International viewers could access the story without waiting for a physical version. Its success, however, created an unexpected consequence in the United States. According to Jason DeMarco, the executive producer overseeing Adult Swim's programming block, the film's runaway earnings made subsequent seasons too expensive to acquire for broadcast. DeMarco's account explained why a two-year gap opened between the film's success and the show's return to American television.

  In October 2023, Adult Swim confirmed that the English dub of the Mugen Train arc would broadcast on its Toonami block. That run aired from the 12th of November to the 17th of December, 2023. The Entertainment District arc followed on Toonami shortly after. The Infinity Castle story arc, which closes the manga's narrative, was adapted into a film trilogy rather than a television season. Its first installment was released in Japan on the 18th of July, 2025.

• 5. Critical Reception

  On review aggregator Rotten Tomatoes, the first season holds a 100% approval rating based on six reviews. Writing for Monsters and Critics, Patrick Frye praised the animation quality and the battle sequences for their seamless integration of digital effects. Writing for Anime News Network, James Beckett singled out the 19th episode as the season's action highlight. Beckett described it as 'a thrilling showstopper of an episode, showing off ufotable's considerable skills as producers of nearly unrivaled action spectacle.'

  Crunchyroll included it in their top 25 best anime of the 2010s, a ranking that mirrored wider critical opinion. Reviewer Daniel Dockery's write-up cited the action choreography, the emotional range, and called the series 'a wonder to behold.' Austen Goslin of Polygon called the show unmatched in its dedication to fights. Japan Web Magazine ranked it first on its list of 30 Best Anime of All Time.

  The Entertainment District arc averaged 18.43 million viewers per episode, consistently ranking among the top animated shows in Japan. Episode 10 drew 25.5 million viewers; episode 11 drew 25.97 million. The Swordsmith Village arc's final episode became the most-watched anime episode of 2023, drawing 15.4 million viewers in Japan. For Comic Book Resources, Sage Ashford ranked the series second among the decade's best anime. He described its leads as 'the most likable male and female leads of the decade.'

• 6. Cultural Reach

  ›

  In November 2020, former prime minister Yoshihide Suga quoted the series during a House of Representatives Budget Committee hearing in the National Diet. Former prime minister Fumio Kishida also identified publicly as a fan, pledging to improve working conditions for people in the anime and manga industry. During Japan's 2021 elections, several candidates incorporated motifs from the show into their campaign materials.

  In 2021, the Red Cross in Tokushima placed characters from the anime on blood drive posters, and the number of donors increased as a result. The show also triggered what producers described as internal tourism, with fans traveling to locations that resembled settings from the series.

  On Tumblr's Year in Review, the series placed seventh in the Top Anime and Manga Shows category in both 2019 and 2020. The following year, the announcement of the Entertainment District arc won the Most Retweeted category at the Twitter Japan Trend Awards. Gadget Tsushin had noted the show's grip on language as early as 2019, placing two phrases on its annual anime buzzwords list: the breathing technique suffix and 'Ah! The era, the era changed again!'

  Yoshiyuki Tomino, the creator of the Gundam franchise, addressed the series in a January 2021 interview. He described feeling jealous of how it had attracted 'such a dedicated and talented staff.' He continued: 'The voice actors are great, the composer of the song that everyone knows is great. So many talented people showed up!' The 7th Global Demand Awards named Demon Slayer: Kimetsu no Yaiba the most in-demand anime series of 2024. It was the third consecutive year the show had held that ranking.
