Yamagishi

Yamagishi is very confident in the skills of his task force and himself. He showed a dismissive contempt of parasites, calling them nothing more than "machines" and treating them as simple pests. He was smart enough to deduce that Gotou was stronger in closed spaces and ordered his squad to the roof. However, he also possessed something of a sadistic nature, such as killing a human who was refused to obey his order, and sacrificing his troops who were being used as shields by Gotou. Though he became distraught over the death of his teammates, he fought until the end.

Yamagishi is a tall, well built man, who has brown hair and brown eyes. In the anime, he has a scar on his forehead. He is usually seen with a formal suit and tie. During the operation against parasites, he wears combat gear.
