Utilizing her own blood, Yosōi Chinoike forms a chakram composed of 20 interconnected hexagons. The chakram itself, as stated by Yosoi, is extremely dense, razor sharp and several times as thin as paper. It can be thrown with extreme speed and guided through the air as it effortlessly slices through opposition like a hot knife through butter. Yosoi often employs it as an assassination weapon, throwing it from long distance and guiding it through the air towards a target. Yosoi is able to initiate turns as small as one degree in the opposite direction while ignoring inertia and the chakram itself can return to the user like a boomerang. At will, the disc can be enlarged from their normal diameter of three feet to nearly any diameter at will. She can form a maximum of twenty chakrams under normal condition. This number is tripled when empowered by a mastered Blood Geist, then doubled once more when enhanced by natural energy. When enhanced by senjutsu chakra, Yosoi can create as many as she has blood for.
