The four members announced their collaboration in November 2022, and released their first self-titled single in December of the same year.

The group members Yoshiki, Sugizo and Miyavi were previously part of the short-lived rock supergroup Skin in 2007.

Yoshiki stated that the mission of the group was to "aim at the international market beyond Japan" and to "preserve the spirit of rock music," which the musician claimed has been overtaken in the modern music scene by pop and hip-hop.
