Shadow breathing:
Shadow breathing is a descendent from mist breathing which is a descendant from wind breathing which is a descendant from sun breathing. It has seven total forms and people that use the breathing style imagine a black trail following their blade with white blinking eyeballs buried in the trail. Color of the blade: dark gray that fades to white at the tip. Weapon: double ended extendable scythe-like nichirin sword. Demon slayer mark: a black eye like mark appears on the user’s forehead, in between the eyebrows with black tear like marks running from the eye, down the bridge of the user’s nose and down their lips to their chin Techniques: First form: Total Darkness: The user tilts the head of the scythe until the tip touches the floor which then creates a wall of shadows around them and their opponent, obscuring the user’s movement and throwing the opponent off. Second form: Voices From the Shadows: The user jumps up and slices at their opponent, aiming for an ear. After an ear from the opponent is cut off, the opponent starts to hear voices out of their other ear (and the other once/if the removed ear regenerates), throwing them off, naturally distracting the opponent and giving an opportunity for the user to take the final blow. Third form: Wheel of Shadows: The user jumps and while in mid-air, turns their scythe in a circular motion in front of them, they repeat this motion as they reach the opponent, slicing the opponent multiple times with both ends of the scythe. Fourth form: Devastating Shadows: The user lunges forward at the enemy and slices at the opponent’s head and neck till it’s ripped into pieces. Fifth form: Shields of Shadows: The user slams their katana into the floor, causing a circle of pitch black darkness surrounding the user, causing any attack thrown at them to hit the ball of shadows and loose all effectiveness. Sixth form: Moving Shadows: This form allows the user to essentially teleport to the nearest shadow in their vicinity. Seventh form: Shadows from the Devil’s eye: The most powerful and dangerous form. This form causes the users blood to rush, causing body heat and grip their sword tighter than ever before, sending a shock wave throughout the katana and shattering one end of their scythe, thus then sending the shattered pieces of the blades to scatter and follow the movement of the users eyes, putting great strain on the users eyes, following a potential risk of the vessels in the eyes to burst. This technique causes the sclera of the eyes to then black.
