Hidaka Ryuta

He was selected to join the group after being one of the finalists from the 2017 Vocal Battle Audition 5 (Vocal category). The group made their official debut on May 22, 2019.

Prior to debut, he was a student in LDH's dance school EXPG in Tokyo.

His dancing talent led him to join the EXPG special dance project Crasher Kidz where they used to perform in the streets. (Fellow BBZ bandmates Riki and Ryusei were also part of this project).

He's was inspired to become a singer by his grandfather who was a member of a folk band The Shadracks.
