Hee, I'm glad you're enjoying it!! I love Nyanko-sensei's cranky little voice too.

Upthread, re: girl in glasses in 2nd season OP--it's actually Sasada, the class rep (she's definitely shown up in the manga bits you've read so far). They make her look much more imperious than she is in the manga, heh (well, they make her slightly moreso in the anime too). I actually like her a lot--to me she escapes being the bossy class rep stereotype, but I know other people don't always agree.
