Hm, this may be a little random, as I'm not sure if anyone's mentioned it...
But wasn't Jun from Rozen Maiden also a sufferer of hikikomori? I think that's when I first heard of the condition. His character was withdrawn from society and he spent all his time in his room ordering stuff online... anyway, not to get off topic, since Rozen Maiden is a different anime altogether.
On a more topic-oriented note, the premise of this series interested me. The thought of "Genshiken, but more serious" is promising. (By the way,
is there going to be a second season for Genshiken?) Oh, and the opening theme is very nice.
But can GONZO really pull this one off? Most of their recent works aren't exactly their "best". I wish they'd make more series like Last Exile and Gankutsuou...
