OMFG SHAKUGAN NO SHANA TOTALLY ROCKS!!!
I currently have the first 2 volumes of the anime series on DVD (with volume 3 due out over here next week) and I just can't describe how much of an amazingly cool and thoroughly enjoyable series it is! Shana herself is absolutely AWESOME!
I really must make the time to buy the 3 volume (so far I think) manga serie sof this aswell to read as I'm so totally hooked right now!
