Angels Die Twice

There is another world with angels of light and darkness waging a perpetual war. Dead in their world, they are reborn on Earth. Living among people each of them is to complete their own mission. When angels of light die on Earth, they return to their world to become immortal, while angels of darkness disappear forever. They say when there is none of them anymore, Death will be defeated. By dying twice angels make us closer to eternal living.
