Tom Tonhat of "Escapist" praised the cast because it inspired multiple cosplaying and praised the Earl's characterization for how he tricked people into reviving others, a theme he found dark. Like Osman, Brain Henson of Mania Beyond Entertainment enjoyed how both the Earl and the Noah clan, who have been working for him, have made the storyline darker. Additionally, in later arcs Anime News Network writer Anne Lauenroth found the Earl's characterization more intriguing as he was shown in a more sensitive way after failing to find his former comrade, Nea. In early episodes, while finding Allen outstanding, Kevin Learthers said the Noah such as Road and Tyki were more interesting characters than most of the exorcists.
