The harvested humans (also called Yoshoku ningen which translates to "Cultivated people", or Plant People in some translations of the manga) were the mindless drone slaves of the Saint Beasts. They are essentially zombies with milky, pupil-less eyes and green skin. While they were not shown to be real humans, they were the plausible result of using the shadow sword on a normal one. They were slow and shuffling but could still be overwhelming in large numbers. A very large number of them are defeated by the combined power of Hiei, Kurama, and Kuwabara.
