Orias Oswell is one of the prestigious professors who teaches Astrology at Babyls Academy, a school in the demon world.
Oswell is a lean tall demon who has blonde eyes that always look stern with bags under his eyes and has blonde-colored hair. Unlike the other male staff that clothes the Babylus teacher uniform, he wears his trademarked all-purple hat and suit, and also wears a pair of white gloves.
Oswell is known to be very prideful specially on his family's magic, but doesn't speak much aside from giving lessons during school.
Oswell is briefly seen teaching his Astrology subject to students.
