Btw, I am like 98% sure that Serawi's VA has a role in OniAi (
http://en.wikipedia.org/wiki/Oniai), although her role is very minor as one of the heroine's friends. Specifically, I noticed how similar they sound alike in ep2 (13:11 into ep2, she is the dark haired friend with hair that touches her shoulders and has a triangular hair clip), where said friend has a few lines that sound extremely similar to Serawi's VA.
Unfortunately, no websites like MAL or ANN have info on the minor characters thus far, so I can't verify one way or another. I'll keep an eye out though, since I'm curious.
