There was a period of Japanese history long ago that was never recorded, a dark time when the island of Japan was ruled by demons. A powerful God-Devil named The Infernal One blazed a burning trail across the Empire, leaving nothing but ash and death in his wake. The villagers of Mount Chokai, seeing the destruction across the land and fearing The Infernal One would destroy the mountains themselves, decided to fight back. It is believed that the people of Mount Chokai fought so valiantly, so bravely to protect the mountains, that the Earth itself decided to act on their behalf. The greatest fighter of their village was resurrected as the Ghost Samurai, a spirit with a heart of ice cold enough to freeze the Infernal One with his touch. For centuries the Ghost Samurai travelled the land, slaying the Oni Fire Demons until eventually destroying the Infernal One himself. Japan was returned to normal and history forgot about the Ghost Samurai and the people of Mount Chokai.
In 2007 a fragment of bone was purchased by the Tetsuo Corporation that once belonged to the Ghost Samurai. Through genetic engineering and the dark arts of necromancy, the Tetsuo Corporation was able to replicate an army of Ghost Samurai’s to serve them. Whether the original will return is still unknown.
Ghost Samurai is undead, which means he does not feel pain or suffer any of the afflictions of the living, such as pain, fatigue or hunger. He also radiates an aura of cold that will freeze skin on contact, lower the temperature of his surroundings and extinguish fires, both natural and supernatural. In a country built primarily of wood and rice paper, the value of this ability to the Japanese people is tremendous.
