She isnt really an angel.. er.. she was a girl, who got really sad and angry and then it started to rain blood and these wings burst out of her.. and .. there is actually a really long story about this.. like, she is with her fiance and then he gets killed infront of her and then the murderer is going to kill her but she falls to the ground and sprouts wings and sobs and the rain falls to the ground. Red rain. Blood. She kills the murderer and flies of into the crimson skies. Very cool. ^^ I like it. Yeah, I'm morbid, but what can I say?
