I generally like co-eds. This group looks interesting on that avenue; three boys, two girls, one of the girls looks like being a black-japanese mix, interesting. They seem to be good dancers. My main objection is the music however; it departs too far from what I enjoy. So I think I'll pass on this one.
I think the SAVAGE is more meant to be a hip hop group. I do know some of the boys were contestants on PD101 Japan, though I can't recall which one. If you're into co-ed groups, then I'd recommend checking out AAA, lol, GENIC and Re:Complex.
