|Anime||Boruto Episode #78|
A mysterious man, he is very ambitious and treacherous as he desires to overthrow the Fourth Tsuchikage and reshape the world in his own vision of "peace".
Like important Iwa figures, Kū dresses in a green and red robe. His face is mostly obscured by some form of mask except for his right eye and a slight showing of brown hair.
Kū is seemingly capable of using an Iwagakure kinjutsu, Akuta, to create golems made from stone. His might in battle lets him confidently engage the Fourth Tsuchikage, during which, he showed noticeable taijutsu prowess as he defended himself from her attacks. He also is apparently skilled in kenjutsu wielding a large cleaver-like blade.
Mitsuki's Disappearance Arc
Main article: Mitsuki's Disappearance Arc Kū met with Kirara and Kakō in what appears to be some type of research facility for the production of Akuta. Later, feeling that his preparations were complete, Kū, Kakō, and some of his artificial soldiers successfully attacked and abducted Kurotsuchi.
