The madōgu are mystical objects created by the Hokage that grant their users special abilities, such as allowing their users to manipulate certain elements (as in the case of the "Fūjin", which allows its wielder to manipulate the element of wind) and enhancing their user's strength/skills (as in the case of the "Dosei no Wa", which increases its user's physical strength and the "Idaten", which increases its user's running speed). Two madōgu creators were mentioned in the manga: Kokū, who creates madōgu to protect the clan and their loved ones, and Kaima, who creates madōgu solely for killing.
