When on a mission, they wear porcelain demon-masks of ghostly white to hide their identities and as a symbol of the pact their clan made with the demon-spirits. Today ghost-faced killers act as assassins and spies for hire, a mercenary clan that hides behind a guise of open and honorable conduct. No one ever discovered the clan?s honorless actions, and to this day, no one knows what clan the ghost-faced killers came from.
Donning terrifying masks to hide their identities, warriors of the clan crept into the imperial palace, and through the evil power of the pact they had made, passed invisibly and intangibly into the imperial household and murdered the entire imperial family, plunging the country into bloody civil war once again. The clan members struck a dark bargain, and the demon-spirits they had contacted provided the clan with a means to the bloody ends they desired. Through sorcery, the spellcasters of the clan beseeched dark spirits to reveal a way that their clan might survive the coming strife and take revenge on the emperor who sought to crush them. Long ago, a persecuted clan of dangerous warriors sought a way to take revenge against their oppressors.
