Noyamano, Shiraume

野山野白梅

Known as Ume to her family, she is the youngest of the sisters. Her hobby is creating puppets in the guise of gorgons, and she is always seen carrying one with her. She is supposedly the weakest member of Sleeping Forest in terms of AT fighting skills, though as a gravity child, she is able to battle extremely well in the Tropheum.
Ume is the youngest child in the Noyamano family, being only 10 years old, and thus is more doted on among the sisters. She keeps to herself for the most part, playing with her weird dolls, which she apparently makes herself. Her personality is more quiet and passive compared to her aggressive sisters, and she seems to have eccentric tastes. She wears a strange eye patch in her hair and is often dressed in long-sleeved dresses that seem much too large for her. As with the other Noyamano sisters, she dotes on Ikki like a part of their family, though Ringo is the only one to have stepped from a brotherly-sisterly love to a romantic relationship in the family.
Though she is the weakest of the Gravity Children, she can easily defeat Ikki in the Tropheum, due to her being accustomed to fighting in 0G; however, this was in a comical context and therefore, her true capability is unknown. She is often bullied by Ikki, which she often holds grudges over, but loves him all the same. She introduced Ikki to the 'Sensei' who designed Kogarasumaru's emblem and Team Shirts.
It has been confirmed that Ume is a Ring Road rider, and it is likely that she could use it in an offensive manner like Kanon does. Her skill with technology is shown to be of extraordinary standards, from creating a 'rocket AT' for Ikki early in the manga (which was scrapped due to her not being in her right senses at that time) to creating strange spiderlike robotic machines which she uses to travel on. Her speed is shown to be on par with genius Tuner Kururu, as they both repaired the robot they were riding on the second it was dismantled by a Time Road user.
