Midnight Opera manga volume 1

Some among the undead feel that now is the time, in the midst of human complacency, to strike against the mortals in a coup that would leave humanity at the mercy of the "dark creatures." Of course, it is at a time of human complacency that dogmatic agents in the Catholic Church also feel ready to strike against "evil," with just as little regard for the cost to human life.The power to stave this ultimate, destructive conflict between evil and righteousness rests in two wise and powerful undead brothers. The only problem is they haven't spoken to each other in a hundred and fifty years.
