Izak didn’t ask for this. One moment, he’s just an ordinary man, and the next, he’s thrown into a medieval fantasy world, one torn apart by war. Two kingdoms are at each other’s throats, and behind the chaos, angels and demons play their own deadly game. After days of wandering in this strange land, Izak finds himself face-to-face with a dying demon, exiled from Hell. With her last breath, she offers him blood magic, the only chance he has to survive. She will become his sword, bound by sacrifice, and he will carry her will into the heart of the war. Now, with a sword that thirsts for blood and a power he barely understands, Izak has no choice but to walk a dangerous path. The world is dark, and it’s getting darker, but if he can fulfill the demon’s final wish, maybe, just maybe, he can find a way out. Or die trying.
