Angel Beats - Coming to an End

Many of you know, Angel Beats will be officially ending with it's 13th episode on June 25th. So sad, I thought that this anime would eventually bypass 13 episodes, but I guess we'll just have to see how it will end. I would definitely miss this anime as much as I missed Kimi ni Todoke. Before I watched this anime I thought it'd be a typical angel vs human thing with action and all but as the series progressed further it got better and better. Now it's on it's final episode

Episode 13 - Graduation:
Heres the sad preview...
Compared to the usual latin-guitar music for the preview, this preview was accompanied with piano background music.
