"Crush" expresses @onefive's desire to destroy things of that nature, which hold them back, and to move forward in a new way instead.

This concept is encapsulated in the lead song on the album, "OZGi", pronounced ojigi, with its Japanese theme and bowing dance.

[11][12] The album represented a shift for @onefive toward the direction of hip hop, especially with the release of the single "Justice Day".

[14] The single "Miraizu" (未来図), released digitally on November 6, 2022, marked @onefive's major label debut with Avex Trax.

[15] It was used as the theme song for the live-action television drama adaptation of the manga If My Favorite Pop Idol Made It to the Budokan, I Would Die, which was first broadcast in October 2022.
