The youngest Ukime on the timeline, Yuki Ukime hails straight from Issaigakure and was a standard kunoichi who was abducted by Aburame Destra. Put through a currently unknown ritual, Yuki was possessed by 'True Ukime' currently making her the strongest shinobi in the world despite having no control over her mind or body. Not much is known of this Ukime due to her current possession.
As the one true Ukime she prefers to work behind the scenes, only making her presence known when absolutely necessary. She has an intense fear of fire and all things hot as it tends to damage her warped body very easily, hiding away in locations that are cooler or even frigid while her underlings do all the work.
