[1] The song primarily serves as the opening theme from the second season of the anime series Mushoku Tensei.

Inspired by Rudeus Greyrat's return to his journey but alone as shown at the end of the first season, lyric writer Hiroya Hirai aimed to expressed Rudeus' shut-in behaviour through the lyrics and show an inspirational message.

The song was influenced by Sum 41 and Travis Baker with the staff also practising English in order to perform an alternate version.

The theme song was first revealed in May 2023, promoting the second season of the anime series Mushoku Tensei.

Longman re-released it in the jacket and contents of their 2nd major full-length album "10/4", which was released on October 4, 2023.

Animehunch describes the opening sequence of Mushoku Tensei as a visual narrative from Rudeus’s perspective, eloquently portraying his yearning to be united with his beloved.

This sequence portrays Rudeus revisiting his past adventures, as he steadily moves forward.

This staircase signifies his active role in shaping destinies, showcasing his growth.

Overall, this opening captures Rudeus’ profound yearning, personal evolution, and the exciting journey that lies ahead.

[8] Hiroya Hirai, who was in charge of the music, said that he imagined the scene depicted in the climax of the 23rd episode of the first season, in which Rudeus Greyrat stands up and walks away after being abandoned by Eris, and created the song so that it could flow there.

But while he was in the hospital, he learned the drums of Travis Barker, and thought that influence is evident in this album.

Travis Barker's drumming is the type of drummer who goes out front in terms of sound, which fascinated him and influenced the style of "spiral".
