Yuuho features solely in the "UFO-chan" segment of the Dokushin Apartment Dokudami-sou OVA series. Suffering severe mental impairment, she clings to the delusion of extraterrestrial origin. This manifests through childlike speech and behavior, including consistently calling herself "UFO-chan." Her presence occurs after fleeing home upon witnessing her mother engaged in sexual activity with her stepfather. This trauma directly triggers her psychological dissociation, leading her to embrace an alien identity as a coping mechanism. Within the episode, Yuuho takes temporary refuge with the protagonist Yoshio. He grapples with conflicting motivations: harboring sexual interest due to her vulnerability while simultaneously feeling protective of her fragile mental state. Her character remains confined to this single episode, defined by her psychological fragility and the resulting interpersonal tensions.
