thanks for the invite. Yeah it is also one of my most favourite and intersting story's I saw/read so far. I actually never saw one of the anime's you just said. Maybe I was an "Anime fan" in the past, but I started watching less anime than before, as for the manga, I think I read just 4 manga's in my life. lol.
Well I am the ORIGINAL shakugan no shana fan. And it is currently my most favorite story I've ever read/watched. I'm also a big fan of Samurai Champloo, Air Gear( just starting on the manga), and some cowboy bepop. Although, I wouldn't really call myself an "anime fan". I don't like the whole genre like the majority of people, but I do find a few select titles amazing.
