Purple K!ss are a seven member girl group from RBW. The members are Ireh, Swan, Yuki, Na Goeun, Chaein, Park Jieun and Dosie.
The members were first introduced in 2018 through the 365 Practise Youtube channel, a channel created to highlight their female trainees. As the lineup of the group had not yet been decided, there are many trainees who appear in the videos who are not in the group's final lineup. On July 20th, the channel was renamed 'Purple K!ss' and the group released their first teaser trailer. They debuted on March 15, 2021.
