The teaser for the first revealed member features a slow pan across Jaekyung's entire body, giving fans their first of many reasons to be excited for Rainbow's new project unit.

"Rainbow's 4-member project subunit Rainbow BLAXX has been formed with a 19+ rated sexy concept. They will make a comeback towards the end of this month," DSP Media said.

This will be Rainbow's second subunit following Rainbow Pixie in 2011. Rainbow BLAXX will be showing the opposite end of the extreme from Rainbow Pixie, who had a cutesy image, with their mature sexy charms.

The three remaining members of Rainbow BLAXX will be revealed shortly! Who do you think will make the cut?
