Mystic Story is raising anticipation for their first girl group!

On October 11 KST, the agency unveiled a dance video starring the six members of Mystic Rookies that will be debuting together – Suhyeon (from the drama 'ATEEN'), Haram, Haruna, Moon Sua (from 'Unpretty Rapstar 2'), Tsuki, and Siyoon. In the clip, the members show off their performance chemistry as they dance to Ashnikko's "Slumber Party" featuring Princess Nokia. A still from the video was previously used to tease the group's lineup. 

Meanwhile, the group is reportedly debuting this November.
