Her appearance looks similar to the male version of Shingyoku.
Futo's power allows her to change the shape and properties of her inanimate surroundings, like a form of alchemy. This means she can soften the fabric of clothing, strengthen walls, change the warmth of air and water, or build altars and pillars as she wishes. While Futo can't alter the form of living creatures, she can supposedly tan the skin or shape hair.
Her name 布都 (Futo) means 'Capital Cloth'. Her surname is derived from the Mononobe clan, but it can mean 物 (Mono) 'Thing' and 部 (Nobe) 'Part'. Her name 'Futo' (布都) is based on Mononobe no Moriya's younger sister and Soga no Umako's wife's name, 'Futsuhime' (布都姫).
If Futo is Mononobe no Futsuhime, she would be one of the two characters who have had children, along with Suwako Moriya.
If Futo is Mononobe no Futsuhime, and if Soga no Tojikois Tojiko no Iratsume, then Futo would be Tojiko's mother. Tojiko no Iratsume's father was Soga no Umako, Futsuhime's husband. However, this is only a speculation as there is no canonical statement saying Futo is Futsuhime and Tojiko is Tojiko no Iratsume.
