Adrian Raven is an elf and a wizard, posing as a human history teacher at Moperville South. He was first seen at the end of the Hidden Genesis story arc as Grace and Ellen's history teacher, and was later revealed to have Nanase and Justin among his students as well. He was described by the school principal as "creepy and weird", and he has shown keen interest in some of his students, such as Grace, Ellen, Nanase, and a boy with long blond hair, later revealed to be Noah, all of which are confirmed to have some kind of magic ability. His nature as an elf and as a wizard was not revealed until late into the Sister II story arc, when he fought Abraham. He is the son of the immortal Pandora Raven. He has a pet 'cat' named Max who is the same species as Jeremy.
