Their first album sold fairly well, all things considered. I think even better than the Berryz. But they lost a lot with Megu, and they still have a rather strange grouping (the Berryz at least look closer to each other in age, Erika next to Mai is just painful). Plus the name still gets a O.o from me.
But I think this will be a good year for them. They've had a slow build, about time to throw them out there and see what they can actually do.
