No, it’s not about that at all. However, it is what the first background story is all about. Angel Beats! tells you about the story which takes place in an anonymous school acting as a Purgatory for the restless soul. There, Yuzuru Otonashi, the main character for this series woke up in an amnesic state and found a girl named Yuri Nakamura.
She introduces herself as the leader of the Shinda Sekai Sensen (SSS), an organization founded by her to rebel against God. Yuri is planning to defy God by not accepting her death and try to conquery the Purgatory High School instead.
She explained that she is currently battling Tenshi (an Angel) which try to take the soul away so they will accept their death. Therefore, the story revolves around the battle between the SSS member against Tenshi and most of the time the story just jokes around while slowly reveals characters’ development in each episodes.
I would not reveals how the characters are developed but when the story gets intense, it developed very brilliantly. As expected from Key production, Angel Beats! could get your tears falling down like there is no tomorrow. It’s tear-jerking to watch when the characters reveals their unfinished desires in the living world and slowly their companions try to help them to get what they desire. Which in the end got Otonashi thinking why do they fight so hard to defy their death, when you could fulfill your dreams in the world thy currently dwelling.
The closing chapter for this anime is the ultimate tear-jerking episode. I was banging my head to the wall while crying in fascination to the turns of the event of the anime. Those who seeks a romantic love story with a great slice of life, may I strongly recommend this anime that will burst your heart out to the story plot that the anime offers.
