The angel Alexiel loved God, but she rebelled against Heaven when she saw how disgracefully the other angels were behaving. She was finally captured, and as punishment sent to Earth to live an endless series of tragic lives. She now inhabits the body of Setsuna Mudo, a troubled teen in love with his sister Sara. Setsuna's misery mirrors the chaos among the angels, and their combined passions threaten to destroy both Heaven and Earth.
Setsuna's body is dead on Earth, and the two women who love him will do anything to bring it back to life. Kurai, the last Princess of Gehenna, agrees to marry Lucifer in return for a potion to revive Setsuna. She enters the deepest bowels of Hell, where she soon gets lost. Can Arachne help save her, or will a deadly secret doom Kurai to an eternity as the Dark Lord's bride? In Heaven, Sara tries to convince Raphael to resurrect Setsuna--but the archangel refuses to help unless Sara joins him in bed first!
