If you'd like to pick up 10th generation's very first Morning Musume photosets, then you should head on over to HSU. I think they're really nice and since it's their very first goods, I think it's somewhat special.
I think they're a great buy, for any fan of the new generation. I myself will be picking up a Haruka set, since she's the greatest most bestest new member evar. Ehem. -bias-
Other then that, there's a bunch of great Aichan graduation stuff (mostly photosets), but some noteworthy buys as well.
They're pretty nice, but to be honest, I don't like what Ai has done with her hair, but that's another subject. I also don't like how she's gone completely tomboy lately, in her new PV and new photosets. Oh well. The Halloween/Christmas photosets are really nice actually, but they are SO RANDOM lol. I still like them a lot.
If you're interested in anything (plus a lot more that I haven't pictured), please visit HSU here:
