What happens after you die? For a girl named Christine, the answer is Purgatory - a place much like a video game. On her search for answers, she enrolls at the Purgatory High School for Demon Hunters, where her and dozens of other teenagers are given a variety of demon-slaying powers. The series begins with this explosive issue, and the bonds between the members of the Magenta Serpent team begin to form. But are the powers they are given enough to face the growing demon threat, and can the faculty members of this strange school be trusted?
