The myth
Master of illusion and shadows in a war-torn Japan, Katō Danzō blurred the line between deadly espionage and supernatural sorcery. His unfathomable power terrified the most formidable warlords of his era, who, unable to control him, sealed his tragic fate to prevent his dark arts from altering the destiny of nations.
