Noizi Ito is most likely one of my favorite artists.  Her style is so smooth and cute.  She’s done the art for a couple of novel series including Shakugan no Shana and Suzumiya Haruhi, the former being compiled into an manga series and both being turned into an anime series.  She has also been involved in a couple of doujin artbooks.  I’d recommend picking up Guren somtime.
