In Kuura, the war of the gods with the demons, who were bound by ties of magical stones, died out, but prophecies say about the chosen one that will free them by receiving the sword Urtanriel - the Death of the gods. Kirin is a thief from the Night Dancers gang. Climbing into the house, he witnesses the ritual of calling a demon. He doesn't know what he's gotten himself into yet, but the goddess of fortune leads him. Losing a part of the soul, being betrayed and sold, hating your father, singing for the dragon and learning magic - is it luck or mockery? What are close people hiding from him? And why is he being hunted by a prince of demons?
