IMO this is a duo with Tina and Anna. The rest are background dancers. I'm surprised Anna is the leader, because Tina sings the most and has the most screen time.
And it reminds me nothing of K-pop or J-pop, more like good old radio-pop.
At least it seems like girls had a lot of fun making the video, and that matters a lot, flop or not.
Seems like their website is down. Is this when we joke about it flopping so hard that avex just shut down everything

In all seriousness though, they have potential, but maybe not in japan. It's too far away from what the japanese people prefer. This is a very typical one hit wonder song, if you ask me.
