Stone Breathing
Notable Users: Gyomei Himejima, Hisoka Nakayama, and Eijiro Kirishima
Stone Breathing unlike the other original breathing forms doesn't use a katana as it's weapon of choice but rather an axe and flail connected together by a chain. Developed in the Sengoku Era after a hashira of the time failed to learn Sun Breathing. Stone Breathing requires immense strength to perform and also usually requires the user to have a heighted sense of touch. It has the least amount of users due to these requirements. The current Stone Hashira is Hisoka Nakayama with his Tsuguko being Eijiro Kirishima. The weapon has a gray hue due to the color changing properties of the nichrin metal.
Stone Breathing consists of five forms.
1st form, Serpentinite Bipolar. The user throws the axe and flail at a target while manipulating the chain into a rotating gesture creating a drill like attack.
2nd form, Upper Smash. The user throws the axe and flail separate from each other for a pincer attack as they near the target. The user smashes down on the chain with his feet causing the chain to rebound the flail at the target.
3rd form, Stone Skin. The user uses his axe to either kill a bunch of demons or defend against a bunch of attacks by spinning it around them making multiple slashes.
4th form; Volcanic Rock, Rapid Conquest. The user spins both the axe and flail before tossing them for a wide prong attack on the enemy usually both hitting the target at roughly the same time.
5th form, Arcs of Justice. The user unleashes a powerful barrage with his axe and flail with the axe always hitting first shortly followed by the flail from the opposite direction.
