Parasyte (Japanese: 寄生獣, Hepburn: Kiseijū; lit. 'Parasitic Beasts') is a Japanese science fiction horror manga series written and illustrated by Hitoshi Iwaaki. It was published in Kodansha's Morning Open Zōkan (1989) and Monthly Afternoon (1989 to 1994). The manga was published in North America first by Tokyopop, then Del Rey, and finally Kodansha USA. The series follows Shinichi Izumi, a high school senior who is the victim of a failed attempt by a parasitic organism to take over his brain. The parasite, Migi, instead infects and takes over his arm, and both are forced into a peculiar partnership to fight other 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 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?
