Hello,
I got one of mine a couple of days ago too.  I 
laughed so hard, you will never guess what the 
background is!  I almost want to burn it and go 
back to Taro and get a non-matching background 
for it! The background is nothing but a piece of 
bristol paper with black paint on it!  Hahaha, I 
thought it was funny, my friend said "Hey, you 
should put it up on Ebay 'Original Ayashi no 
Ceres background!'"  The cel is great though, it 
deserves a better set than black paint *_*  Enjoy!
