Demon Slayer, manga series by an artist under the pen name Gotouge Koyoharu. Serialized in the Japanese manga magazine Weekly ShĆnen Jump from 2016 to 2020, Demon Slayer (Japanese: Kimetsu no yaiba [âBlade of Demon Destructionâ]) follows Kamado Tanjiro, a boy who joins a secret corps of warriors to avenge his family and cure his sister Nezuko, who has been transformed into a demon. Blending action, folklore, and themes of compassion and perseverance, the series became a cultural phenomenon. As of 2025 it has more than 200 million copies in circulation worldwide (including digital editions), placing it among the best-selling manga of all time.

Gotouge Koyoharuâs 2013 one-shot manga Kagarigari featured Nagare, a blind, one-armed vampire hunter, in a darker, more gothic setting. A 2015 revision, Kisatsu no nagare expanded Nagareâs backstory within an early version of the Demon Slayer Corps. The concept was reworked after editorial feedback, leading to the creation of Kamado Tanjiro. Although Nagare did not appear in the published series, characters such as Tamayo and Yushiro were carried over from the early one-shots, with revised roles and backstories.
Background and publication
Gotouge began a professional career with a short manga, Kagarigari, which introduced a demon-hunting concept that was later refined in Demon Slayer. Serialized from February 2016 to May 2020, Demon Slayer consists of 205 chapters, compiled into 23 volumes. Initially modest in reception, the series experienced a surge in popularity after studio Ufotableâs anime TV adaptation premiered in 2019. By the release of the final volume, more than 120 million copies were in circulation, a figure that continued to grow with each subsequent adaptation. The series ranked first in Japanâs annual manga sales in 2019 and 2020, setting a record in 2020 with more than 82 million copies sold domestically.

Concept and plot
âTo dispel the regrets of those killed, to stop any more victims from appearingâŠI will relentlessly wield my blade against the demons, and thatâs a fact. But I will not trample on the pains of being a demon. Nor on those who regret their own actions. Because demons were humans. Because they were humans just like me.â
âKamado Tanjiro, Demon Slayer, volume 5
Storyline
Set in TaishĆ-era Japan, the series portrays a world where demons stalk the night. These demons were once humans who were corrupted by the blood of the most powerful demon, Kibutsuji Muzan, who seeks to create others of his kind. To combat them, a secret organization known as the Demon Slayer Corps recruits sword-wielding fighters and trains them in breathing styles, which are techniques that enhance strength, speed, and perception. These warriors use Nichirin bladesâswords forged from a unique ore that has absorbed sunlight, one of the few elements capable of killing demons. The corpsâs elite warriors, known as the Hashira, lead the fight against Muzanâs dreaded lieutenants, the Twelve Kizuki.
The story follows Kamado Tanjiro, a kindhearted boy whose life is shattered when demons massacre his family, leaving only his sister Nezuko alive but transformed into a demon by Muzanâs blood. Unlike most demons, Nezuko retains a sense of humanity, fueling Tanjiroâs quest to find a cure that can make her human again and to end Muzanâs reign. Seeking the skills to confront demons, Tanjiro trains under Urokodaki Sakonji, a retired Water Hashira who lives in seclusion on Mount Sagiri. Over two years Tanjiro learns the Water Breathing style, hones his already heightened sense of smell to perceive his opponentsâ emotions and intentions, and develops a fighting spirit grounded in empathy.
As the series progresses, Tanjiro masters the ancient Sun Breathing technique, inherited from his ancestors, while Nezukoâs growing powers make her central to Muzanâs schemes. Together with allies Agatsuma Zenitsu and Hashibira Inosuke, Tanjiro battles the Kizuki, leading to the final confrontation with Muzan in the Infinity Castle and Sunrise Countdown arcs.

Adaptations and media franchise
Episode 19, âHinokami,â is widely regarded as the standout moment of the Demon Slayer TV seriesâ first season. The episodeâs title references the ShintĆ god of fire, Hi-no-kami (also called Kagu-tsuchi or Ho-musubi), a figure associated with both creation and destruction. In the episode Tanjiro recalls a breathing technique passed down in his family, enabling him to perform the Hinokami Kagura (âDance of the Fire Godâ). The sequence transforms his water-based attacks into a blazing fire form, visually rendered as a dragon of flames. This momentâcombined with Nezukoâs awakening of her Blood Demon Art (a unique supernatural ability demons develop, often linked to their blood)âmarks a turning point in the seriesâ narrative and visual identity.
The anime adaptation of Demon Slayer for TV transformed the series from a popular manga into a global cultural phenomenon. The first season, broadcast in 2019, adapts the opening arcs through the Rehabilitation Training arc. Episode 19, âHinokami,â became celebrated for its visual artistry and dynamic choreography, trending internationally on social media. The momentum carried into the 2020 release of Demon Slayer: Mugen Train, a feature film that continued the narrative from the first season. The film broke numerous box-office records, earning more than $500 million worldwide and becoming both the highest-grossing film in Japan and the top-grossing film globally in 2020.
The second season (2021â22) reintroduces the Mugen Train arc with expanded scenes before adapting the Entertainment District arc. In this storyline Tanjiro, Nezuko, Zenitsu, and Inosuke join Sound Hashira Uzui Tengen on a covert mission, which leads to a confrontation with Daki and Gyutaroâdemon siblings who share the title of Upper Rank Six within the Kizuki. Season three, released in 2023, focuses on the Swordsmith Village arc, a chapter in which Nezukoâs immunity to sunlight is revealed. The fourth season, broadcast in 2024, adapts the Hashira Training arc and was preceded by the compilation film Demon Slayer: To the Hashira Training, which received a global theatrical release in February 2024.
The concluding chapters of the manga are being adapted as the Infinity Castle trilogy of theatrical films. The first installment, Demon Slayer: Infinity CastleâAkazaâs Return premiered in Japan on July 18, 2025, earning approximately $40 million during its opening weekend and surpassing the domestic debut of Mugen Train. The film was released internationally on September 12, 2025, in countries including the United States, Canada, India, and the United Kingdom. The second installment is slated for release in 2027, and the concluding part is scheduled for 2029.
The franchise has expanded into other media and commercial ventures. Several light novels (illustrated Japanese prose works typically for young adults) have been published, a console and PC video game titled Demon Slayer: The Hinokami Chronicles was released, and the series has been adapted for the stage. Merchandise ranges from collectibles to apparel, and collaborationsâsuch as themed train and aircraft liveriesâunderscore the influence of the series on popular culture in Japan and abroad.
