Dimitrie Vatler

He is a high ranking vampire and a descendant of the first primogenitor, the Lost Warlord who came to Itogami Island to initially hunt down Christoper Gardos, but it turns out that he actually hired him to activate the Nalakuvera and do battle with it as a means to relive him of boredom, which in the end it was Kojou, Sayaka and Yukina who destroyed it. Though, it was pointed out that he may have some abnormal degree of affection toward Kojou, it is suggested that he is more interested on the Kaleid Blood that flows inside Kojou's veins that was passed on by Avrora than Kojou himself.

After the Nalakuvera incited, he establishes a "Warlord Dominion" consulate at Itogami Island and becomes its consul.
