Angel beats!

The anime centers on a young boy named Otonashi who dies and loses his memory of his life. He meets Yuri, a girl who invites him to join the Afterlife Battlefront (Shinda Sekai Sensei)an organization she founded to fight against God for the cruel fates the SSS members experienced in life. 

This anime had lots of great elements! Loved every second of it!
This was the only anime out of many, that made me cry (just a bit ;) )
