En Zu  

, アン・ズー

En Zu, also known as the storm genie and king of darkness, is an indu gud in the form of a huge eagle with a lion's head. During his first encounter with Pam, he transformed into a malformed beast that was being hunted by Linfa. Pam's heirloom necklace knocked En Zu out and shrank him dramatically, allowing her to claim him as her familiar. Although En Zu does not enjoy the relationship, he looks out for Pam as a familiar should. However, Pam has become convinced that En Zu is a pervert due to his combat form, which resembles a young male devil. Additionally, En Zu seems to have lost some of his memory from before being claimed as Pam's familiar due to psychological trauma caused by his imprisonment and release. Recent information suggests that En Zu is actually a usurper who was previously imprisoned for a long time before going on a rampage.
