Radio x 365 must have sold well. Why else would they make 366? They (or just Asumis) keep saying they won't make any more, yet they keep making more. I'm buying up most of the Hidamari Sketch related stuff, except for the vocal songs and, well, the anime.
The four (+ occasional guest (usually Matsuki Miyu) + Umes) have such an interesting behavior around each other, I can't get enough of it. I must say that Asumi Kana is the central figure that makes this team move in the strangest directions. In a way, I'd love to have Sawashiro Miyuki mingling with them, but I don't think she'll fit in all that well. She recently appeared as a guest for the currently running internet radio, and well, she doesn't really mix up well with Asumis' antics. I still love her, though (^^).
Umes is also great as always. I wonder what she looks like.You can tell who's featured on this CD by looking at the cover image. Don't forget the little green thingy on the right.
