Yuki is a foul-mouthed cynic who works as a photographer for a Tokyo newspaper. She is introduced into the film shortly after the opening. She is traveling to a Godzilla sighting spot with Yuji Shinoda and his daughter Io. After a brief near-death experience with Godzilla, Yuki gets the pictures she wanted, but when she turns them in to her boss, it is discovered that Godzilla's radiation had destroyed the film in her camera. She eventually arranges to go on another Godzilla-seeking outing with the Shinodas, but she is told that she must join the Godzilla Prediction Network to do so. She reluctantly joins, and aids her new colleagues in their quest for knowledge. When she nears the Millennian spacecraft, it begins to hack the files she had about Godzilla. This leads her to break in to her newspaper office to unplug all the computers that the Millennians were hacking for data. Before she can finish, she is met by Yuji and Io who tell her that the building is set to explode. Yuji, having more computing experience, continued unplug computers while Yuki and Io escaped. Yuki is present during the battle between Godzilla and Orga.
