ShuuKaRen was a Japanese dance-vocal duo that debuted in 2016 under Sony Music Associated Records label and managed by LDH. The unit was formed by "Fujii Sisters" from E-girls supergroup: Fujii Shuuka (Also a member of FLOWER) and KAREN (Also a members of Happiness), who presented a mature and modern concept inspired by black music.

On December 31 of 2017 member Shuuka quit the entertainment industry abruptly due to health issues that affected her condition as a performer, specifically dancing. As a result the short-lived but succesful duo released 2 singles and collaborated with artists like PKCZ and m-flo before going into an undefined hiatus. Read more on Last.fm.
