Not that anybody who cares doesn't know all this already, but I have made a
characters/seiyuus page for this show, with pics of the characters and their seiyuus, and some info about each seiyuu. I'm waiting for the opportunity to add Hayami Saori and others.
As I said recently in the ep4 thread, however, I'm not that satisfied with Sakamoto Maaya as Shinobu. Not enough juice there, too dry and normal for me. I love her as a seiyuu, just not here. Maybe I'll appreciate her more as we go on.
