Yosaku Okamura is a journalist dedicated to covering UFO-man and the Ultimate Girls. He actively pursues photographs exposing the Ultimate Girls' true identities, incentivizing this pursuit with monetary rewards. This attracts individuals like Makoto Moroboshi, Tsubomi's older brother and a high school photographer. Upon the heroines' debut, Okamura assigns them nicknames based on physical appearance; he initially dubs Silk "UFO-man P," later revised to "UFO-man Girl" in some releases, incorporating Japanese wordplay ("manko"). His reporting demonstrates a distinct preoccupation with the Ultimate Girls' bodies, especially focusing on states of undress occurring during battles when their suits deteriorate. He works professionally alongside fellow reporter Mayu Koharuno, Silk's older sister. Okamura's journalistic focus consistently centers on sensational aspects of the giant heroines, particularly their transformations and resulting nudity.
