Here stands a city called the City of Redemption, though most people prefer to call it Sin City.
In the east, a genius hatches a conspiracy, hoping to use a mortal body to overturn the laws between life and death. For the sake of a promise made long ago, he has already abandoned everything. When the souls of the dead return, will he truly get what he wants?
In the south, a boy like a bird gives up all power and privilege. He believes he is already free, never realizing that a vast net is closing around him. When the bird is bound by chains called responsibility, where can he turn to find freedom?
In the west, wisdom and reason converge. A scientist seeks to make himself the most perfect human being. To do so, he is willing to cast aside every emotion that makes him human. But can a human who has lost all feeling still be called human?
In the north, a warrior forcefully suppresses every criminal. In pursuit of the truth about the world, he is even willing to challenge those who make its rules. But there are things even absolute might cannot accomplish. One day, he will pay an irreversible price for his arrogance.
At the center of Sin City stands a towering, imposing spire, and the throne of sin looks down upon all living things. Through endless years, a girl waits before the vacant throne, believing that the one who once sat upon it will eventually return.
When everything is settled, the boy who witnessed it all will finally absolve everyone of their sins. Then, go uncover the truth of the world.
