In a modern-fantasy world where the line between living and death is always thinner than one could imagine, people no longer have faith in exorcists. A boy from a long-traditional exorcism family - who doesn’t believe in it, takes a chance to give up his ancestor’s inheritance and makes his own choice for the far future. Will this decision lead him to a different life, despite the fact that he has potential to become the strongest exorcist to ever exist, or will the bloodline continue?
