Igor has brown, long hair, as well as pale skin. He wears an eye-patch over his left eye, which was burned out during the Blue Night when he was possessed by Satan. He wears the standard Exorcist uniform, a full black coat with black pants. He also keeps bandages on his fingers and arms, which contain summoning tattoos underneath.
Due to being possessed by Satan during the Blue Night, Igor lost his left eye to Satan's blue flames, as well as his family when he killed them under Satan's influence. Because of this, he hates Satan immensely, as well as any Demons related to Satan. He seems to believe that as Satan's son, Rin can only be evil at heart and must be destroyed no matter what. Ironically, he is extremely loyal to Mephisto, another one of Satan's sons, and was able to put aside his hatred for Rin and stop attacking him when Mephisto asked him to.
HistoryDuring the time of the Blue Night, he was possessed by Satan for a moment and used to kill his own family. Unlike other victims of Satan's possessions, he survived because only his left eye was possessed. This has caused him to despise anything related to Satan, including Rin.
True Cross Academy arcDuring the Exwire exam, he is the one that summons a Naberius to attack the candidates. However, Neuhaus intentionally directs his Demon to attack in order to see his blue flames. After the exam, he has a verbal confrontation with Yukio where he justifies his actions, saying that he never intended to kill Rin, and was only operating as ordered.
The next evening, Neuhaus attempts to assassinate a sleeping Rin. However, the plot is foiled by Yukio and Shiemi, who had moved a still-sleeping Rin into another room. Igor attempts to flee to the roof top and summons a host of minor Demons to distract the gun-wielding Exorcist. On the roof, the Tamer distracts Yukio with more minor Demons and prepares a summoning circle to summon an enormous, upper-class Naberius. Rin appears to assist Yukio, and the two team up to subdue the upper-class Exorcist.
Refusing to lose, Neuhaus continues to attack Rin. The half-Demon accepts the blow, but demands that Igor attack him without involving bystanders. Shocked, the elder Exorcist departs, but not before telling the Okumura brothers that there many people who want the son of Satan dead, especially among Exorcists.
It is later revealed that Neuhaus was secretly following the orders of Mephisto Pheles in an attempt to further awaken Rin's demonic powers. Some time after this he departs from the cram school, and his role is taken by Shura .
