Kyoichiro

Kyoichiro was a modern human depetrified in the year 5739 by the Tsukasa Empire, where he became a soldier. Kyoichiro was characterized by a petrification mark that went horizontally across his face, connecting his eyes and going over his nose, somewhat resembling the frame of a set of glasses. His hair was of an ash-blond colour tied into a small ponytail. (Source: Dr. Stone Wiki)
