Now he's been approached by two mysterious victims of the invation: Tamiya, a beautiful schoolteacher, and Shimada, another student. What do the aliens want with humanity, and with Shin?.

An alien parasite has infected the body of a high school boy named Shin. As the parasite begins to dominate Shin he fights to maintain his humanity.

High school student Shinichi continues to try to save his soul from a parasytic alien who has invaded his body.

Shinichi thinks he may have found an ally in his fight against aliens who can control the minds of humans when he meets Kana, a girl who can also detect the parasites.

"They arrive in silence and darkness. They descend from the skies. They have a hunger for human flesh. They are everywhere. They are parasites, alien creatures who to survive must invade--and take control of--a human host. 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?"--Back cover.
