A bunch of us talked about the idol stuff in sheepy's plurk the other day. Since we already lost Kotori a few months ago, and Maki and Nico just dropped, the idol stuff is being kept kind of loose on the whole at this point, with less emphasis on keeping a big group together. Hanayo will still be pursuing idolhood full time, Rin will most likely help her out here and there between exploring, Honoka is focusing mainly on adventuring and training her Pokemon, Nozomi's going to lean more toward the development of the Fey family half of her CR, and I don't remember what Void said about Eli. But everyone also sort of agreed that they'd get together and sing and dance sometimes too since they're all still friends. So whatever direction Umi goes is pretty much your call. Hanayo would be happy to perform with her, for my own part.
