The Infernus Scholasticus (School Hell) is a binding curse put on Evangeline A.K. McDowell by Nagi Springfield.

Used as a way to force Evangeline to experience life as a normal girl instead of a hunted vampiress, the curse binds Evangeline's basic powers, while her immortality and youth remains, and physically forces her to remain within the boundaries of Mahora Academy and Mahora City.
The only way Evangeline can break the curse is for Nagi, or a blood-relative of Nagi's, to lift it.
