The title track serves as the third overall opening theme song for the Jujutsu Kaisen anime television series.

[1] The first press limited edition includes the DVD of the live performance of the one-man tour "Unknot/Reknot" held at Zepp DiverCity (Tokyo) on October 15, 2022.

In producing the music, Kitani received an offer from the anime production side, "A song with a refreshing impression based on the theme of youth".

The first arrangement of this song was completely different, with a slower BPM, more sad elements, and a bit of a guitar on a club beat.

"Scar", which he wrote as the first opening theme song for the Bleach: Thousand-Year Blood War anime television series, is one of them, and when he was writing the chorus of "Where Our Blue Is", Kitani was thinking about that.

[10] For Jujutsu Kaisen, the video primarily deals with the youth of Gojo and Geto, with an emphasis on blue backgrounds, like the lyrics say.

The opening contrasts with the ending theme, "Akari", which uses a more relaxed melody and also makes emphasis on Gojo and Geto's friendship.
