Gyutaro is a petty and jealous demon who happens to be one of the Twelve Kizuki, a group of especially powerful demons who directly serve Muzan Kibutsuji, the original demon who is responsible for the creation of all other demons. Gyutaro's clash with the Demon Slayer Corps. is generally considered one of the highlights of Koyoharu Gotouge's original manga, and anticipation for the animated version of their battle has been high ever since Season 2 was revealed to be focusing on the Entertainment District arc.

The new opening sequence is set to "Zankyou Sanka," the funky new opening theme song by Japanese singer Aimer. The song is the first theme for the anime series to not be sung by pop star LiSA, who provided the theme songs for the anime's complete first season and Season 2's previous Mugen Train arc. The anime's original theme song, "Gurenge," became a mainstream hit, receiving a Platinum certification from the RIAJ, the Japanese equivalent of the United States' RIAA. The composer of the song revealed that the royalties she earned off of the song were enough to make her a millionaire.
