With news of KARA members Nicole and Jiyoung leaving the group, the attention has been focused on which girl group will step up at this opportunity.

Strength - Cute & sexy

Weakness - No big hit

Opportunity - Sexy unit Rainbow BLAXX

Threat - Girl's Day, Dal Shabet, AOA, and other sexy girl groups

One of DSP Media's oldest girl group KARA is in trouble with Nicole withdrawing from the group, and Jiyoung's upcoming withdrawal from the group. Kyuri, Seungyeon, and Hara are still there, but the big question is if they will be able to redeem themselves with such few members. That's where Rainbow stands. Will they be able to step up at this opportunity?

Rainbow debuted in 2009 with their song "Gossip Girl." They've definitely advanced over the years, with songs such as "A," "To Me," "Tell Me Tell Me," and "Sunshine." The members showed off their cute looks and tall figures, all the while switching back and forth from cute and sexy, appealing to the public with their various charms. They've become more well-known with Jaekyung and Go Woori's appearance on different broadcast shows.

Rainbow didn't have any trouble entering the Japan music market, either. In 2011 they sought to conquer with "A." Since then, each one of their singles has ranked in the top 10 on Oricon's daily charts. They are being recognized as a new Hallyu group in Japan. Last year they held a solo concert titled 'Rainbow Festival' in Tokyo Roppongi, where they were able to show off their earned popularity.

But there's a limit to Rainbow. They're a rainbow of 7 different colors, but there isn't a good keyword to describe the group as a whole. They grabbed the fans' attention with their exposed stomachs in "A," but it's difficult to say they've had a huge hit in their activities following "A." They still don't have an explosive fandom, nor do they have a song or dance that's been extremely popular or trendy. Perhaps that's why they've stood in KARA's shadow as their "sister girl group."

Therefore, Rainbow's unit Rainbow BLAXX's comeback is extremely important. Rainbow BLAXX is Rainbow's 2nd sub-unit, the first being Rainbow Pixie (Hyunyoung, Seungah, Jisook), who came out with a cute image in "Hoi Hoi." While Rainbow Pixie emphasized 'cute,' Rainbow BLAXX will be emphasizing 'sexy.' Their shocking 'paparazzi' teaser images have definitely raised expectations for their upcoming performance.

And the competition is fierce. Girl's Day, Dal Shabet, and AOA have recently put forth their sexy concepts, and it's going to be a hard battle. It's hard to stand out, and they'll need to differentiate themselves with a unique strategy and a great song in order to achieve success.

Rainbow already has 5 years of experience under their belt. It's about time they show something amazing. Right now is the time for Rainbow to give it all they've got, especially while KARA is finding is place again. Rainbow BLAXX' showcase will be held on the 20th. The question is, Will they be able to make a big hit with their new song "ChaCha?"
