Igor Neuhaus

Igor Neuhaus is an elite Polish Exorcist and Academy lecturer who holds the titles of Tamer, Doctor, and Aria. While his appearance is marked by an eyepatch and intricate incantation tattoos, his primary motivation is a vendetta against Satan, the demon who destroyed his family and blinded his left eye. Despite this hatred, he remains unwaveringly loyal to Mephisto, even sparing Rin during his early years to carry out his master's specific commands.
