PhD: Phantasy Degree, Volume 1

Sang is a fearlessly spunky young girl who is about to receive one hell of an education...at the Demon School Hades! She's on a mission to enroll into the monsters-only class, so she meets up with a creature clique that turns her into a vampire. Now Sang can focus her monster matriculation on what's really on her mind: acquiring a mysterious, magical ring from the fiancee of the chief commander of hell!
