Summary
Referred to as Ume by her relatives, Shiraume is the youngest of the Noyamano sisters. She is a ten-year-old girl who is notably doted upon by her siblings and tends to keep to herself, displaying a quiet and passive demeanor that contrasts sharply with the aggressive nature of her older sisters. Her eccentric personality is reflected in her hobby of crafting puppets designed to resemble gorgons, which she carries with her at all times. She is frequently seen wearing long-sleeved dresses that appear excessively large for her frame, along with a peculiar eye patch worn in her hair. Within the Sleeping Forest, Shiraume is considered the weakest member regarding standard AT fighting skills. However, as a gravity child, she possesses exceptional combat abilities within the Tropheum, where she is accustomed to fighting in zero gravity. Although her true capabilities remain somewhat mysterious, she demonstrated the ability to easily defeat Ikki in the Tropheum, a feat presented in a comical context. Despite being frequently bullied by Ikki and holding grudges against him, she harbors deep affection for him, viewing him as family. Like her sisters, she treats Ikki with great care, though Ringo is the only sibling to have transitioned their relationship from sibling-like to romantic. Shiraume exhibits extraordinary technical skills, having designed the emblem for Kogarasumaru and the Team Shirts, and introduced Ikki to the 'Sensei' responsible for their creation. She is also a confirmed Ring Road rider, likely capable of using the technology offensively similar to Kanon. Her ingenuity is evident in her creation of a 'rocket AT' for Ikki early in the manga, a project abandoned due to her lack of focus at the time, as well as her construction of strange, spider-like robotic machines used for transportation. Her mechanical aptitude is comparable to that of genius Tuner Kururu, as evidenced when she and Kururu simultaneously repaired their dismantled robot immediately after it was taken apart by a Time Road user.
