ShuuKaRen

ShuuKaRen was a Japanese Dance-pop and EDM duo formed and managed by LDH in 2016. They were a sub-unit of supergroup E-girls and signed to the record label Sony Music Japan. The duo was composed of sisters Shuuka and Karen Fujii (hence the sub-unit's name), making them the first joint unit of members from the groups Flower and Happiness. This was also the first time Shuuka provided vocals to a musical project besides being a performer.
