Neron Zullen is a demon-like humanoid freelance worker on Earth, exiled from his homeland due to automatic magic taking over all jobs. After finishing his studies, he was forced out. 

Neron is an introvert who prefers staying indoors or maybe is just lazy. He struggles with socializing, often communicating more with computers than people. With a sullen face and quiet demeanor, he seems unapproachable, but when he talks about something he loves, he can be joyful and talk endlessly. He has a blunt, somewhat rude speaking style, and an irregular sleep schedule has led to poor eyesight and dark circles. As a low-level demon, his health is nearly the same as a regular human's.
