Long years have passed since our time, and the world now lies in ruin. A new segregation has formed between believers and non-believers, and the believers are the minority. In a world that has forgotten its faith, there lies one last hope. The unicorns of God embody ultimate purity and righteousness, but if they are all destroyed then the Dark Lord will take control over mankind. It is in this attempt that he sends his dragons into their land to attack. All but one of these precious creatures are killed, and the one remaining unicorn has no choice but to flee into the world of man to escape. Here, she is transformed into a woman and learns that she is a foretold prophet, meant to save the world of man from its wicked ways. Suddenly, this untainted creature must deal with the strongest of human emotions, and the fact that her once-immortal body is now growing tired and weak. Amid all of this, she must prevail, for if she fails, so does all hope for mankind.
