Lei Magnus (Shabranigdu)
Position: Assitant Headmaster
Source: Slayers
Description:  Tall, dark, and foreboding, Lei Magnus is a dark shadow that lurks around campus.  One of the few people on campus that can look Rezo in the eye, Magnus has black hair to match his all-black clothing, and a staff that defies the laws of physics - the decoration on top is not connected to the rest of the staff.  His eyes are blood red, and tend to glow in the darkness that usually surrounds him.  The mazoku (spirit demons, for those unfamiliar with Slayers) on campus, and some of the others, know him also as Ruby Eye Shabranigdu, the Demon King of the Mazoku.  As such, he has absolute authority over the Dark Lords who are on the faculty, and over any other Mazoku studying and working at Moku U.
Role on Campus:  On his own, Magnus is someone you really try to avoid bothering or messing with.  He has a sense of humor, but it's a typical Mazoku sense of humor - twisted and sadistic.  It's known that he both respects and fears the Headmistress, which often worries the students, since it implies that she's worse than Lei Magnus himself.  When things go wrong on campus, Magnus will tend to leave them be, although sometimes he does intervene...usually after being seen leaving the Headmistress's office.  He's the only person the Headmistress contacts on campus, and the only person who officially knows who she is.
