#dokuchi

Dokuchi lost his right arm in his youth to a demon attack, which lead him to discovering the Corps and persevering through training to join them. His technique is akin to fencing to facilitate his one-handedness. After finishing the final selection, he was assigned Saiboku as his swordsmith, who had already been creating prostheses for slayers with disabilities; his side project was trying to engineer prostheses that could emulate the kind of human movement Yoriichi Type Zero could do (a task made more difficult seeing as he was not permitted to take it apart).

Suspending some disbelief as to how the prosthesis works, think of it as a rudimentary form of automail from FMA. There are gears inside the arm and joints, along with a few wires that are attached to the musculature of the wearer to facilitate more natural movement. It would be a highly invasive procedure, one that Saiboku did not want to just test on anyone until he knew of a less invasive way to affix it to a slayer. But Doku was certain he wanted to try Saiboku's prototype.

The arm is made of Paulownia wood! "Empress Tree or Princess Tree", traditionally planted at the birth of an aristocratic baby girl and fashioned into a dresser on her wedding day. Its light, warp resistant, and the low silica content reduces the dulling of blades. Perfect for sheathing and protecting a hidden blade (like Hyakkimaru's prosthesis from Dororo).

Doku can fight two-handed now with the prosthesis, and it makes every day life much easier, but he tends to prefer his one-handed style as it's what he's used the most.

Age: Equivalent of 26 Pronouns: He/Him Height: 5'10" (177.8 cm) Blood Demon Art: Toxic Blood English VA: Jonah Scott (As Legoshi from Beastars)

Dokuchi has forgotten much of his human life, and has been left wandering the earth for far longer than he had hoped. The victim of a mass poisoning in his village, the wisteria toxins saturating his blood at the moment of transformation would eventually create a blood demon art not only toxic to humans, but demons as well.

“Toxic Blood” allows Dokuchi to transform his blood (and saliva) into an irritating, corrosive substance at will. As it requires open wounds to be most effective, his regeneration speed is sacrificed during its use, allowing free flowing blood as ammunition. If used too long, the toxins saturate his circulatory system and will eventually alter his mental state, leading him on manic and violent killing sprees.

His missing limb, damaged eye and scars do not seem to heal at all, even when the rest of his body regenerates.
