"As far as I'm concerned, Masca is the hottest new manhwa out there."-SequentialTart.com An otherworldly tale of devils, wizards, and unrequited love in the tradition of Neil Gaiman's Sandman ! Asarella is the clumsy apprentice of the great white mage Elywho. Little does she know that the mage harbors a secret love for her, which will only complicate her training to prepare her for the apocalyptic battle to come. For ages thirteen and older.

The shocking back story of the master mage Eliwho is revealed! In a mystical land in another universe many years ago, the novice sorcerer Eliwho is forced into a shady contract with the sinister Devil of Sibilla. Now, five hundred years later, minor details of that encounter will have a lasting impact on not only Eliwho's life, but his entire kingdom!

The Devil decides to save Asarella and follows her to the realm of the dead. Powerless without air, he meets the ruling devil of that realm who refuses to let Asarella go. In the human world, Eliwho casts the spell of awakening, calling Asarella's soul back to the world. She comes back to life, and Eliwho tells her that the Devil saved her. How will she repay him?
