Summary: (ANN)
In a world after death, angels fight for their fate and their future. Yuri, the leader of the Shinda Sekai Sensen, rebels against the god who destined her to have an unreasonable life. On the otherhand, Tenshi, the chairperson of the student council for the world after death, battles against the SSS members. SSS members utilize armed weaponry to battle it out against the angels harnessing supernatural powers.
I know I ever said that girl+sword= win, but I also think the same thing with girl+gun.
The other thing if you look closely at the main character, Yuri, she will resembles Suzumiya Haruhi a lot!! except with different hair and eyes color. hmm SSS = the new SOS Dan.
