In terms of changing his body, he can alter his face into possessing two more pairs of eyes while also elongating his forehead. Most notoriously, he uses this ability to create an extremely durable and sharp katana, complete with a tsuba, tsuka, and its own scabbard. Because of this, his katana can never be destroyed as he can regenerate it like he would with normal wounds.[25] He also displayed the ability to grow and protrude dozens of blades from his body, allowing him to perform a multitude of slashes from them without a swinging motion. From its activation alone,

he uses Crescent Moon Blades: Complementing his Moon Breathing, his Blood Demon Art allows him to create and manipulate dozens of sharp blades shaped like traditional crescent moons from his flesh katana. They are implied to be created from his blood and can be either a bright yellow or a bright blue in color. These crescent moon blades are innately chaotic, constantly changing in size, direction and speed, making his attacks extremely unpredictable and unreadable as they have no set pattern at all. his Blood Demon Art greatly enhances the power of his techniques, making every single one of his sword swings extremely deadly and dangerous. He also seems to be capable of using his Blood Demon Art as long as his katana is unsheathed, allowing him to create crescent moon blades even without swinging his sword or unleashing a technique. The volatile nature of his Blood Demon Art makes it extremely challenging for his opponents……..his Blood Demon Art seems to have a secondary ability which allows him to manipulate the shape and range of his sword slashes when unleashing his Moon Breathing techniques. His slashes usually create and are surrounded by a red/orange crescent shape that carry his crescent moon blades. he seems to be able to control said slashes to a certain extent, increasing their range and shape to attack his target in impossible ways under normal circumstances. When he distorted his katana into its branch-like appearance, his slashes turn into a light purple color. he displayed the ability to exponentially increase the range of his sword slash with his Moon-Dragon Ringtail technique and shape his slashes into a circular drill-like shape with his Drilling Slashes, Moon Through Bamboo Leaves technique.
