Short for Brand-new idol Society, BiS was founded in 2010 by Pour Li, who decided to give up her solo career and audition members for a new “alternative” idol group. ∙ In true idol fashion, BiS has gone through three different versions of the group—the first two being led by Pour Li—and more than two dozen members. ∙ In 2013, BiS briefly added a surprise new member, JK, who turned out to be famed fashion designer Junko Koshino. ∙ BiS is the flagship project of WACK, a music production company that manages several dozen idols and numerous groups, frequently swapping members from one outfit to another. ∙ Following the 2018 departure of Pour Li, BiS was briefly split into two groups, BiS 1st and BiS 2nd, which competed for fan votes and record sales. ∙ Their 2019 single “Are You Ready?”—an 11-plus-minute track inspired by Queen biopic Bohemian Rhapsody—was selected as the closing theme for anime series Yu-Gi-Oh! VRAINS. ∙ Their 2020 album, LOOKiE, contains several homages to Green Day’s breakthrough album, Dookie.
