Demon Slayer: Kimetsu no Yaiba is a dark fantasy multimedia franchise created by Koyoharu Gotouge, following Tanjiro Kamado's journey to turn his demon-transformed sister Nezuko back into a human and defeat Muzan Kibutsuji. Originating as a manga serialized in Weekly Shōnen Jump from 2016 to 2020, the IP has expanded into a globally successful anime series by ufotable, record-breaking feature films, spin-off literature, and video games.
Created by manga artist Koyoharu Gotouge, Demon Slayer: Kimetsu no Yaiba debuted in February 2016.
Set in Taishō-era Japan, the franchise tells the story of Tanjiro Kamado, who joins the Demon Slayer Corps after his family is slaughtered by the progenitor of demons, Muzan Kibutsuji, and his younger sister Nezuko is transformed into a demon.
Across its multimedia expansion, the IP encompasses a 23-volume core manga series with over 200 million copies in circulation, multiple light novels, spin-off manga including Kimetsu Academy!, a four-season television anime produced by studio ufotable (comprising 63 episodes), and feature films. Its theatrical releases include Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train (2020), which became the highest-grossing film in Japanese box office history and the highest-grossing anime film worldwide, alongside compilation films and a planned trilogy adapting the climax Infinity Castle Arc beginning in 2025.
The origins of Demon Slayer: Kimetsu no Yaiba trace back to creator Koyoharu Gotouge, who first published a Kimetsu no Yaiba Side-Story one-shot in Shueisha's Jump GIGA on July 20, 2016.
The main manga series launched serialization in Shueisha's Weekly Shōnen Jump on February 15, 2016, running through May 18, 2020, and ultimately collected into 23 tankōbon volumes. The franchise's initial development rapidly expanded beyond print.
In 2019, light novels written by Aya Yajima with Gotouge's illustrations began releasing, starting with The Flower of Happiness in February 2019. That same year, Ryōji Hirano authored spin-off manga works such as Giyu Tomioka Gaiden and the 4-panel comedic webcomic Kimetsu no Aima!. The IP reached mainstream global stardom when studio ufotable adapted the manga into an anime television series directed by Haruo Sotozaki, premiered in April 2019, covering the Unwavering Resolve Arc across 26 episodes.
