"The time of the falling is beginning. Will the Angels suffice, or will the Fallen reign the world?"
Mizuka, a fifteen year old girl, finds herself in a mystical life when she finds 2 small spheres in her backyard. Holding both in her hands, the two souls of the spheres enter her body, she's now a living host. The dark soul, Fallen is the leader to the fallen angels planning to take over the world. The lighter soul is an angel without a name, but simply called Angel. The two souls now have a place to stay, but they pay a deep dear price. A normal human can't take the strain of such powerful souls, so Mizuka is slowly slipping away. (AKA DYING)
Will the two souls realize what is happening and stop the war before it's too late?
