Ulthury, also known as Urutori or Rulutieh in specific contexts, originated as crown princess of Onkamiyamukai. She inherited the position of Oruyankuru from her father, Waabe, assuming leadership duties. Physically, she has long blonde hair usually in a loose ponytail, blue eyes, and distinctive white bird wings. Her attire features a circlet with a green jewel, a green hair accessory, a white leotard under green pants secured with a belt and sash, a green scarf, arm warmers, and simple white tabi-like shoes. Her personality blends kindness, maturity, and perceptiveness, leading her to guide others. A strong maternal instinct defines her, resulting in deep attachment to Fumirul, an abandoned infant she cared for. This attachment drove her to attempt keeping Fumirul instead of returning her, revealing stubbornness and selfishness alongside her nurturing nature. She later reconciled this, returning Fumirul after acknowledging the necessity, though Fumirul maintained their bond and eventually returned to regard Ulthury as her mother. After Tuskur's establishment, she volunteered as a mediator and chose residence there despite Munto's objections. She became guardian of Hakuowlo's sealed resting place, awaiting his return. During the Yamatan Civil War, she continued as Oruyankuru, supported Karulau and Touka in founding the Hakurokaku inn in Yamato, and intervened to deny the Eight Pillar General Woshis information on Hakuowlo's location. Her relationships are extensive: Camyu is her younger sister, whom she cares for despite frequent scolding over mischief. Karulau is a childhood friend, often seen sharing sake. Her connection with Hakuowlo varies; they are great friends in the anime, while the visual novel depicts a deeper relationship, including spending a night together, with implications she recognized his true nature as Uitsualnemetia's benevolent aspect. She comforted and counseled Eruruu regarding her grandmother's death and feelings for Hakuowlo. She acted as a maternal figure raising Kuon. Her bond with Fumirul persisted despite earlier conflict. In the *Lost Flag* spin-off, she engaged in activities like playing with children and carrying them while flying. She encountered Akuta, taking him flying where they witnessed a theft. Despite initial hesitation, she complied with Akuta's request to drop him onto the thief. Afterwards, she tended to his injuries, lectured him about recklessness, and assumed responsibility for his care that night. Within the *Mask* storyline, she appeared as Rulutieh, youngest princess of Kujyuri, part of the Yamato empire. She undertook diplomatic missions, like accompanying tribute to the Imperial Capital, often with her pet Hororon bird, Cocopo. She interacted with Haku (the amnesiac protagonist) and Kuon's group during travels, displaying characteristic grace and approachability despite noble status. She participated in alliance-building efforts, such as treaty signings, amidst conflicts like invasions by Kuccha Keccha forces and the scheming of figures like Niwe and his winged advisor.
