"Parasitic Beasts") is a Japanese science fiction horror manga series written and illustrated by Hitoshi Iwaaki and published in Kodansha's Morning Open Zōkan and Monthly Afternoon magazine from 1988 to 1995. 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 parasyte organism to take over his brain. Instead of burrowing into his brain, the parasyte landed in his hand and matured partially up his arm.
