An 800 year-old Old Blood born in Poland on April 1, Zelman Clock called 'Red-eye Zelman', and is the bearer of the God's Flame and a legend of the Dark Ages. Zelman has many other titles including "The Ancient Dark Hunter", "The Follower of the Fire God", "The Red-eyed Murderer", and "The Prince with Blood-colored Eyes". He is also one of the rulers the four affiliated houses of the Special Zone. He comes from a glorious bloodline linking to the great warrior, Asura and is noted to be one of the last of that bloodline.
Having inherited the special blood of the war god Asura (闘将アスラ?), Zelman has a power called 'Eye Ignite', which enables him to create and control fire. Zelman has a wild side, but his real self seems much nicer. He doesn't share the grandiose superiority of his underling, August. He values his freedom, and has a soft spot for honesty, and cheerfulness, like that of Kataro. He taught Kotaro that a vampire's fate centers around the voices that come from the blodline, passed on if they listen to the blood. Also, before his confrontation with Jiro, despite his sense of anticipation of the confrontation, Zelman is able to hide it and keep it under control. He is the only one of the vampire leaders who willingly accepted Jiro and his brother to the Special Zone as he enjoys their personalities.
He is a leader of the non-officially-sanctioned group called The Coven. Because he had to prove his bloodline, and had to go through a fight, he was the only one that was left; which is also due to his lifespan of 800 years.
