Try Red Garden.
Its about 4 girls who died and got brought back to life to fight humans who turn to beasts...
You'd think its your regular kill em all anime but its got a deep story and a shit load of character development. Some would find it overly melodramatic, but if you think about it, its actually not. It starts real slow and gives you bits and pieces over the course of the series.
If you can get through the 1st few episodes and the silly singing parts, you'll apreciate it a lot.
