RAISE A SUILEN

 is an all-girl band in the BanG Dream! franchise. The group consists of Raychell on vocals and bass, Kohara Riko on guitar, Natsume on drums, Kurachi Reo on keyboard and vocals, and Tsumugi Risa as DJ.

They were tentatively given the name THE THIRD (仮) before getting their official name which was announced during their second live.

Background
Initially, the group was formed solely as a backup band due to the voice actresses of Afterglow, Pastel*Palettes and Hello, Happy World! being unable to play their characters' instruments, with the band giving the vocalists a chance to perform. However, they also have their own original songs. It was later revealed after the second live that they officially have become part of the BanG Dream! franchise. Furthermore, it was also announced that they have been given an official band name, RAISE A SUILEN in addition of a newly recruited member, Tsumugi Risa.
