Osakabehime features in the comedic OVA series *Fate/Grand Carnival*, embodying her signature role as a socially awkward, reclusive princess. During the "ServantTube" storyline, she ventures into streaming on a video-sharing platform to amplify her online presence, resorting to over-the-top fanservice antics like suggestive poses and exaggerated gestures. These efforts backfire when her account is promptly banned for breaching community guidelines, underscoring her habit of masking social insecurities through increasingly outlandish antics—a direct nod to her canonical communication and self-expression struggles. The series sidesteps her mythological origins as the yokai overseer of Himeji Castle and her *Fate/Grand Order* narrative significance, instead spotlighting her humorous mishaps within the carnival’s zany, surreal escapades.
