The Angel that Shattered Dreams

This is a story about Angels. They aren't your average Angels either. This story follows a man by the name of Keita. He lives alone in a house on the edge of a small town in the middle of nowhere. He discovers a very peculiar "woman" on his doorstep. He takes her in and discovers that she isn't human, his brother is coming to kill him, and he's got only one year to get strong enough to beat an angel who killed the Creator Goddess in the beginning of creating the human race. There is one more thing to add, that the "woman" isn't a woman, it's an Soul Collector by the name of Minori. And she is a he.
