Rainbow's unit group Rainbow BLAXX revealed the 3rd member of their group.

On January 9th Seungah was shown caressing the length of her body in a teaser image. She showed off her sexy waist line with a sexy pose.

Seungah has been loved as a beloved lady of Rainbow. However, in the unit group Rainbow BLAXX Seungah is embarking on the greatest exposure yet. Rainbow BLAXX' main concept is "19 and over," so it's only natural that she would shed her usual image and show a 180 degree transformation.

Her agency DSP Media stated, "She's a 'glamour goddess' in the team that's stayed hidden until now. She'll be stepping up as a hidden card of Rainbow BLAXX that shows off the dual charm of innocent and sexy."

Rainbow BLAXX revealed a comeback teaser image on New Year's Day with photos that resembled "voyeur" type polaroids. Jaekyung and Hyunyoung have already revealed their images for their upcoming comeback.
