A third live band started from the BanG Dream! Project; the group consists of Raychell as LAYER (Ba. & Vo.), Riko Kohara as LOCK (Gt.), Natsume as MASKING (Dr.), Reo Kurachi as PAREO (Key.), Risa Tsumugi as CHU² (DJ). They started out as a backup band at "Garupa Live & GirlParty", and have been supporting the live stage since with their highly skilled musical performances.

After that Raychell, Natsume and Kurachi formed a band with the provisional name, THE THIRD(TBD). Kohara was added during the 1st live performance on March 25th 2018. On July 17th 2018, the addition of Tsumugi and the official name of the band,「RAISE A SUILEN」was announced during the 2nd live performance. Their activities, including the live stage at the Ryogoku Kokugikan in December of the same year and Nippon Budokan on February 22nd 2019, just 73 days after their official debut, are simply remarkable. RAS will continue to create their unique world and musicality with their original songs.

Fans will not be able to keep their eyes off from them and their phenomenal technique of musical performance! The group is also globally well-known due to frequent appearances of the group in overseas events and conventions like Anime Expo and CharaExpo USA in North America.
