RaNia was a girl group under DR Music. They debuted on April 6, 2011 with the digital single "Teddy Riley, The First Expansion In Asia". From 2016 to 2018, they promoted as BP RaNia (short for Black Pearl RaNia). The group presumably disbanded in 2020 as member Hyeme announced that she would start anew as a part of BLACKSWAN. A bunch of members.
