An Angel's Obsession

Greta Gallagher is a type of girl you wouldn't call normal. With her beautiful appearance and high social status, she's the type who would catch anybody's eyes. To make it worse, she's in the top class of the prestigious school of Sword's Academy.
But when she catches a certain angel's eye, her life turns even more abnormal.
Taking a gang of angels with him, power angel Daniel Hayes, sets out to the human world to go win her heart and escapes from the gates of heaven without permission.
In fury, Heaven takes action. Calling up a dominion angel, a virtue, a throne and a very confused guardian angel, they send them to the human world to capture Daniel and send him back.
Will the four angels capture Daniel in time or will they be too late and let all hell to break out in heaven? Will Daniel succeed in making Greta fall in love with him or is there a completely different love taking part?
