ShuuKaRen was a Japanese female dance and vocal duo, composed of the Fujii sisters, both members of E-girls, active from 2016 to 2017. The duo marked their entry into the music scene with the single "UNIVERSE," which gained initial attention as the background track for an Apple's Beats by Dre commercial featuring E-girls in April 2016. On August 11, during the final day of the "E-girls LIVE TOUR 2016 〜E.G. SMILE〜," the formation of ShuuKaRen was officially announced, and it was revealed that "UNIVERSE" would be their debut single. The single was subsequently released on October 5, 2016. The members of the group were Hana Fujii (also a member of Flower and E-girls), who served as a vocalist and performer, and Kana Fujii (from Happiness and E-girls), who contributed as a vocalist, rapper, and performer. The group's journey was short-lived, as they disbanded following the elder sister, Hana Fujii's decision to retire from the entertainment industry on December 31, 2017.
