|Title(s)||The Purging Duke, Inquisitor of the Tanar'ri (self-proclaimed)|
|Power Level||Demon lord|
Alvarez, known as the Purging Duke, is the demon lord of Torture and Inquisition.
Alvarez is a master of torture who searches the ranks of the tanar'ri incessantly for signs of the taint of Law. As a mere petitioner, he outwitted the nalfeshnee of Woe who judged him, and served as a maggot-loving chasme and then a powerful glabrezu assassin (for 3,000 years) before gaining a demonic form closely resembling his living one: a human man with oily blue-black hair. His clothing is immaculate, but a light of insanity burns in his eyes.
Alvarez is famous for the brutalities he inflicts upon his own troops. Even demons fear his inventive torments.
Alvarez dwells on the 57th layer of the Abyss, known as Torturous Truth.
