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?

Won the 1993 Kodansha Manga Award for General Manga and the Seiun Award for Best Comic of the Year in 1996.

Comparable to "Gyo"'s philosophies of humans fusing with micro organisms.

Except, this is far better.

its a great series. kind of annoying however that they stopped scanlating with only under 5 chaps left. the scanlation teams need to work onn projects like this, not everyone doing naruto and bleach. ramblings aside, its a great series, thatll keep u on ur toes. once u start reading, youll be in for a surprise, and expect a few twists along the way

At first I thought that the plot sounded silly -- an alien living in a guy's hand? -- but seriously, this is very cool and makes you think about how fictional the idea of a universal morality really is. The comparisons between an alien culture and human psychology are just beyond awesome. Not to mention that the central character's eventual change -- both in outlook and in biology -- is so powerful and personal. Very gripping, fast-paced and well-written! Don't miss this manga. smile

This is good shit. Can't describe it much better than the other comments or the description, but it's fun and involving. The alien vs human relationships are very interesting, imo. I love it.

Just wish they'd finish scanlating it now.

Initially, Kiseijuu was >really< interesting to read. The artwork is kinda stiff, but the story made up for that. I loved it. However, the last volume, which was abrupt & forced, disappointed me. I didn't feel satisfied at all. It ruined the whole series. =.='

This is definately an awsome manga, but a word of caution-- it is graphic. It starts out almost cute, but very quickly gets rough. For squeamish people like me its torture because the story is good enough to keep me coming back, and the violence is enough to keep me up. Definately have lost sleep over this one. But if you can stomach some gore, and don't read it right before bed, truely captivating.
