Neuhaus, Igor

イゴール・ネイガウス

An Upper First Class Exorcist and Academy lecturer, holding the titles of Tamer, Doctor, and Aria.
He wears an eyepatch over his left eye, with Aria incantations tattooed on both arms.
A youthful encounter with Satan cost him his family and the sight in his left eye, fueling his intense hatred for Satan and associated demons. Ironically, he remains fiercely loyal to Mephisto, obeying any command, which led him to cease his attacks on Rin before she became an Exorcist.
