Angel Beats! Background +BlackGlassEnhanced??

It is really amazing that I can download Angel Beats! Win7 theme. It is hard to find and most of them have virus. Unlike sorano, Angel Beats! (AB) has its own way to express the most important character-angel. Even though at last she admit that she is not angel but she still can use those special abilities. For instance, handsonic is a way of offense enemies. It has four different versions. Each version is getting cooler and cooler. However, I am going to talk about a system which can make our background cool. I know I have some reliable websites which can download theme fast and safe. I think science is kind of interesting for me. I finally understand why Ms.Liu said it's fun to write chemical formulas and equations. I think I improve a lot in it even though I still have no confident. Ah~ We have poetry contest tomorrow. I wonder who will win this year XD. I hope our classmates can all win.
