Ley von Crimson River is a haughty and cold aloof daughter of the family who desires pure destruction and fighting despite being a "moderate". She is stubborn, as her servants of the family run around ragged trying everything to please her. Her father sent her to the human world to locate Dio, her childhood friend and leader of the Burning Canyon tribe.
Peter von Crimson River is the highest order in the family and Ley's father. However, not much is known about him, although he did send his daughter to the human world to find Dio and secure their allegiance with the Burning Canyon family after learning the Burning Canyon's suspicious activities.
Jeeves is a fiercely loyal servant to the Crimson River family, more specifically Ley. He does everything in his power to help the aloof daughter, even going so forth to actually fight for her.
