From Tokyopop:

Maeve, a succubus-in-training, is sent to the human world by her mentor, Veril, to learn how to blend in and hone her skills of seduction. However, things get a little complicated after she meets Aiden, a smart, but unmotivated student at her new high school. Unfortunately for her, Sylne, the head succubus of the Demon World has sent a spy to catch any missteps her former protege. Between Aiden's witchy girlfriend, his nutty best friend, biology class, and Demon World conspiracies, Maeve is going to be lucky to make it out of high school alive!

Note: Finalists in Tokyopop's national Rising Stars of Manga competition, Ashly Raiti and Irene Flores have created a Gothic romantic fantasy set in one of the most menacing worlds known to humans: high school.
