According to the legend, five hundred years ago, there was an insignificant lord who possessed a mysterious power that drew ayakashi (supernatural creatures) to him. A demon exterminator, Tokimori Hazama, was called upon to protect the lord and his castle. The lord's power stayed on the land even when he had died. Thus, Tokimori founded the Hazama clan, who inherited his techniques, to protect the land for centuries to come. This land is Karasumori .
