Takeshi Hirokawa is the one of main antagonists of the anime/manga series Parasyte. He is the Mayor of East Fukuyama City and the leader of a cabal of Parasites which counts Reiko Tamura and Gotou among its members. He is eventually revealed to actually be a human who sympathised with the Parasites, believing they were the key to taking humanity down a chain or two.

He is voiced by Yutaka Mizushima in the Japanese version of the anime and John Gremillion in the English version.


Hirokawa was a well kept man; he had short, brown hair that neatly combed back. He had an average height and build, and was always seen with a formal suit and tie.


Hirokawa was a level-headed man; his demeanor usually was calm and kept without expression, which made people mistake him as a parasite. He believed that humans are toxic, and greatly disapproved of how the human race treats the planet and all the other species around them. Being sympathetic with parasites, he truly believed they were the answer to cleansing the planet of humans and assumed them as trash.
