Utilizing shape transformation and her smoke kekkei tōta, Kemuri creates a couple of smoky shuriken. Since these shuriken are made up of shape transformation, Kemuri can change the shape and size of these shuriken, allowing her to make them more useful for their purpose. Because they are made of smoke, they do not have much offensive power, however, they can be thrown at an opponent and coordinated to explode once near the opponent, inhibiting their sight. Depending on the density and size of the shuriken, Kemuri can also utilize smoke's choking effects, which would allow her to subdue a large amount of people in a efficient manner by means of suffocation. Thus, she prefers making fūma shuriken, as their larger size gives her more smoke to work with.
