THE DAY EVIL TRIUMPHED

Mephisto has won. Somehow, he's broken free of his seal and taken everything Ard ever cared about in an instant. No one can defeat the Evil God -- not even the reborn Greatest Demon Lord. However, there's still a chance. Mephisto will relent if Ard can prove that his bond with his friends is strong enough to resist the devil's control. But such a feat requires nothing short of a miracle. How will Ard reach out to his friends when everyone's under the spell of his worst enemy?
