When I saw YGA at the Oshipan Live there weren't a lot of people there, and at least half of them came for Afilia.
They've been doing this for 5 years now and there aren't any signs of them actually making it big, so yeah.
It still sucks because it's a fun group but I'm not that surprised. I think YGA is one of many idol groups that will be disbanding in the next year or two.
