The group was formed as a new project from the three remaining members of DEEP by adding three new members who were the winners of the DEEP VOCALIST AUDITION in 2019.
On July 22, 2019, a live event titled DEEP VOCALIST AUDITION ~FINAL STAGE~ was held at Akasaka BLITZ where the members of DEEP revealed that the group would continue activities as a trio. However, they also started a new entertainment project titled "DEEP SQUAD", including three new members who were the winners of the audition out of 12.000 contestants: Uhara Yuhi, Sugiyama Ryoji and Higa Suzuki.
