Rayne woke up with no memories of the apocalypse. Samael is just... a delinquent, who happened to find Rayne at a rooftop. They both ended up making a deal in order to survive in a world where cannibalistic monsters roam.
The art is amazing, I love how everything has a pinkish/purple hue. I adore the story line, i've always liked apocalyptic things and the character designs are so pretty. The main character is so cool AND a girl AND not a damsel in distress which is GREAT. I honestly couldn't ask for more besides more chapters because I can not get enough. It's just the perfect mix of pretty and dark.
