Featuring vocals from voice actresses Yoshino Aoyama, Sayumi Suzushiro, Saku Mizuno, and Ikumi Hasegawa, the album consists of songs featured in the anime series, including a cover version of Asian Kung-Fu Generation's "Rockn' Roll, Morning Light Falls on You", as well as newly recorded material; nine singles preceded the album's physical release.

[2][3] In November 2022, it was announced that the band will release a self-titled album, consisting of 14 tracks including those featured in the anime series.

[16] Kessoku Band performed the album's songs at their Fixed Star concert, held at Zepp Haneda in Tokyo on May 21, 2023.

[19] In a review for Mikiki, Shi called Kessoku Band "a truly exceptional piece of music that does not get stuck in the usual 'anime song style'".

The reviewer stated that the album is in the vein of Japanese rock music, and that the "metal-like" lead guitar creates a unique structure that "did not seem to exist at the time of the 2000s and 2010s".

[29][30] Kessoku Band remained at number one in the Digital Albums Chart for four consecutive weeks, marking the first time a female group achieved that record.

[35] It also topped Oricon's year-end Digital Albums Chart with 70,132 downloads, which is the first time a female group took first place in the ranking.
