Losing their war against Heavens angel army, the demons of Hell are on the cusp of collapse. As a last ditch attempt to turn the tides of the war, the demons send Akutsu Masatora to the mortal plane on Earth to save their homeland from the angels. Disguising himself as a high school student, Akutsu seeks to recruit someone with the capability to lead the demons to victory.

Akutsu does not have to look far: among his classmates is the magnificent Lily Amane, a transfer student who seems like the perfect candidate for Akutsus plans. But as luck would have it, Lily is one of the very angels that Akutsu is meant to be fighting against, and his attempt to recruit her might end up being the biggest blunder in the failing war. Worse yet, Akutsu may fall in love with his own worst enemy.
