But when she gets expelled for being a delinquent, her mother, fed up with her daughter's wayward ways, sends Mafuyu to an isolated school far off in the country. Determined to make the best of the situation and make her mother proud, Mafuyu decides to turn over a new, feminine, well-behaved leaf. But her fighting spirit can't be kept down, and the night before school starts she finds herself defending some guy who's getting beaten up. One slip wouldn't have been a problem, except the guy is…her teacher?! How can Mafuyu learn to be a good girl if her teacher won't let her forget her wicked past?

    They descend from the skies. They have a hunger for human flesh. They are everywhere. They are parasites, alien creatures who must invade - and take control of - a human host to survive. And once they have infected their victims, they can assume any deadly form they choose: monsters with giant teeth, winged demons, creatures with blades for hands. But most have chosen to conceal their lethal purpose behind ordinary human faces. So no one knows their secret - except an ordinary high school student. Shin is battling for control of his own body against an alien parasite, but can he find a way to warn humanity of the horrors to come?

    But instead, her ambitions land her in the clutches of a gang of unsavory pirates led by a devious magician. Her only hope is Natsu, a strange boy she happens to meet on her travels. Natsu's not your typical hero, he gets motion sickness, eats like a pig, and his best friend is a talking cat. With friends like this, is Lucy better off with her enemies?
