I heard a song from an Anime called Shakugan No Shana

And it sounds a LOT like this one
YouTube - Tsubasa Chronicles Soundtrack- A Song of Storm and Fire (http://www.youtube.com/watch?v=SxdOPosahXo)

It has the same chords and choir sound, but it's a different song.
Could someone help me find out what it's called please?

The song I posted is similar, but it isn't it. If you can find it and post a link, I would be VERY happy.
That way I can play it and see if it's right.

Thanks for the help!
:)

If it's not from that one, It's from
• Pandora Hearts or • Vampire Knight

I'm almost positive it's from Shakugan No Shana though, and I think it's during a lot of the battel scenes when they put up this thing called a "fuzetsu"

Once again, Thanks!

Also, I think the Artist is
Yuki Kajiura
