BLACKSWAN in a promotional photo for their 2020 album Goodbye Rania
BLACKSWAN (previously known as Rania, then BP Rania) is currently a 4-member group consisting of Youngheun, Fatou, Judy, and Leia. The group debuted in 2011 as Rania with the single album Teddy Riley, the First Expansion into Asia and the title track of "Dr. Feel Good", but later changed their name to BP Rania (from "Black Pearl Rania") in 2016 after then-member Alex was made the leader as a reference to her skin tone. After that, the group went on to release 2 more title tracks and promote 2 more B-sides before finally rebranding as BLACKSWAN in 2020 with a 5-member lineup that later became the current 4-member lineup after Hyeme left the group.

- Taiwanese singer and actress Sarah Wang was part of Rania's pre-debut lineup, but left the group before their 2011 debut and later opened a Hello Kitty restaurant in Beijing known as the Dreams Restaurant.
- The group's company later filled her spot using Thai trainee Data (who left due to homesickness) and Canadian trainee Minhee (who left due to parental disapproval) and, lastly, former member Yijo.
- As a last-minute addition to Rania's lineup, Yijo never participated in any of the performances for her group's song "Dr. Feel Good" and left shortly after Rania's debut due to working visa issues.
- Seonghyun left BP Rania some time before the group rebranded as BLACKSWAN.
- Hyeme left BLACKSWAN after she was accused of scamming 50 million won from someone because DR Music had already planned for her to leave the group when her contract expired; BLACKSWAN's promotions for their Goodbye Rania album were cut short after this.
- In an interview with YouTuber Ploopy678, former member Yina stated that many of Rania's members left before their contracts expired by either stating their intentions to leave in order to gain permission from their company to leave or leaving without the permission to do so.
