Orgelt Kazakov is a minor antagonist in the Japanese light novel series Madan no Ou to Vanadis, being the Lord of Polus, a territory in the kingdom of Zchted. Kazakov is described as being a large, broad-shouldered man with a thick brown beard. Orgelt, also known as "Bloody Kazakov" was renowned for being on of the greatest warriors in the kingdom, favoring a mace in battle. He also, however, was renowned for his hatred of Vanadis Elizaveta Fomina, who he believed to be cursed because of he heterochromia (possessing two eyes of a different color).
Kazakov was also known to be hot-headed and impulsive, a trait that meant he was easily manipulated by Maximilian Bennusa Ganelon. Kazakov hated Elizaveta for defending Eugene Shevarin, who was falsely accused by Ilda Kurtis of an assassination attempt actually perpetrated by Valentina Glinka Estes. Ganelon also falsely claimed that Elizaveta had kidnapped Brunish earl and series protagonist Tigrevrmud Vorn.
Kazakov's forces met the armies of Elizaveta, accompanied the forces of fellow Vanadis Eleonora Viltaria, and Tigrevrmud Vorn himself at the Battle of Birche Lake. During the battle, Kazakov personally kills ten men, and also manages to fight on even terms with Eleonora Viltaria. In spite of his combat skill, however, Elen kills Kazakov, decapitating him with her longsword, Arifar.
After Kazakov's death, his forces are quickly defeated. Those nobles formerly allied with Kazakov that survived the battle instead ally themselves with Valentina Glinka Estes.
Kazakov is, in some respects similar to Robert Baratheon of Game of Thrones/A Song of Ice and Fire in his younger years. Like the younger Robert, Kazakov is a large, bearded man who wields a blunt weapon (a warhammer in the case of Robert, a mace in the case of Kazakov) with great strength in battle. Robert was also known for being a great warrior, but a poor leader, who leads a rebellion. However, unlike Kazakov, Robert is successful in his rebellion. It is not known of the similarities between the two characters was intentional on the part of the author of Madan no Ou to Vanadis or not.
