Who made the music for Demon Slayer?

Demon Slayer's score is shared by two composers with distinct territories. Yuki Kajiura, known for her choral and string driven writing for series such as Fate/Zero, supplies the series' ceremonial and emotional voice, while Go Shiina writes much of the action and folk inflected material, including themes built on Japanese instruments. Between them the score manages the adaptation's core contrast, village quiet against demonic spectacle.

The songs carried the series into the general public. LiSA's opening theme Gurenge, from the first season, became one of the defining Japanese pop hits of 2019 and 2020, performed on the year end Kohaku broadcast, and her Homura, the Mugen Train theme, repeated the feat a year later, winning the Japan Record Award. Later seasons rotated artists, with Aimer among the most prominent, but the LiSA pairing remains the franchise's musical signature.

Music is also where the episode 19 story becomes audible. That episode's climax introduced a vocal insert drawn from the Kamado family theme, arranged as a cathartic release after twenty episodes of instrumental restraint, and the soundtrack albums that followed sold the moment back to the audience. Japanese soundtrack releases from the anime are substantial multi disc sets, issued alongside the Blu-ray programme.

Collecting the music is straightforward compared with the discs: the singles and albums were mass market Japanese releases and remain easy to find, with first press sleeves and anime tie in editions as the variants to check. A Demon Slayer shelf that holds the manga, one fanbook and the Gurenge and Homura singles documents the phenomenon in something close to its full shape.
