Goshogake serves in the covert G-Men Hot Springs agency, defending Japan’s thermal springs from threats alongside her partner Ibusuki, both under the command of Captain Kusatsu. Her codename, drawn from the Goshogake hot spring, follows the group’s tradition of adopting onsen names as aliases. She cuts a striking figure in a yukata tailored with a high slit reminiscent of a Chinese dress, contrasting sharply with Ibusuki’s abbreviated, modernized yukata and crimson boots. A rigid dietary regimen restricts her to consuming solely bulgogi during health spa visits, blending discipline with peculiarity. Her duties pit her against YUZAME, terrorists targeting hot springs. Missions span reconnaissance and direct clashes, including a botched infiltration of YUZAME’s Chichibu base that led to her capture alongside the Nohara family. Captors deployed unorthodox leisure-based torture to force revelations about the fabled "hot water of the soul of gold," a mystical spring central to the conflict. A shared vulnerability with Ibusuki lies in her crippling sensitivity to Shiatsu massage techniques, a weakness mercilessly exploited by adversaries like YUZAME’s Killer Joe Finger, whose torturous massages induce debilitating pain. Available records detail her role in the 1999 film but offer no insights into her origins, motivations, or appearances in other media, leaving her history and broader narrative trajectory undefined.
