(originally named Angel Girl + Dance with Devils) Ai, and immortal or as the demons call them Angels or minor gods. She's been sent to earth to take care of a girl. Not any girl, a girl that is the grimoire, a magic book hidden inside of her that can allow any one to destroy or conquer the world and even kill God. But then you throw in hot Devils in to mix and the story really kicks off. The cover was made by @cranerain .
