Damn, four tie-ins? And they're no small fry cafes or chains neither. They're really putting some stock into this group so hopefully this means we'll see some strong debut sales.
Usually, an idol group starts off pretty... rough looking and the girls have to grow and go through some styling changes before they show their full potential. I've noticed this group is already pretty polished image wise, not in an artificial way either. I guess that's the benefit of debuting right away with a major label than an indie one.
They definitely have plenty of beauties to work with. Miria, Sora, and Rikako keep catching my eye.

Miki has an interesting look to her that I like too (those gorgeous cat eyes).
@LunaLupus: I have this bad habit of ignoring/disliking lead girls. Unless they have a quality that immediately appeals to me like Miyabi (in the early Buono! days) or Atsuko Maeda then I tend to be harsher on them than the other members. I dunno why.
