Against them stands only the traitor Amon, in the body of human Fudo Akira. His deeds have not gone unnoticed. Lord Atrocious, the Monster Shogun-strongest of demonkind-demands Amon's head! The strongest demons from across the world descend upon Japan, seeking Akira's life, even Lord Satan himself! It's one demon against the world-but Amon won't hesitate to kill anyone who stands in his way.
