Kiseijuu

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 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
Shinichi 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?
