BanG Dream is a Japanese music media franchise created by Bushiroad, built around all-girl bands and the mobile rhythm game Girls Band Party, released in 2017. Imai Lisa is the bassist of Roselia, while Mitake Ran is the vocalist and guitarist of Afterglow, two of its most popular groups. Clips of their voice lines circulate widely in the Bandori fandom, shared in edits and fan compilations. This joint scream became a handy standalone reaction because it captures both performers out of character in a brief, expressive burst.
