Slasher

He was also shown to be quite arrogant at times, looking down on the Flame Hashira, Kyojuro Rengoku, and boasting his speed in front of him, as well as challenging him to a duel twice. However, Slasher was not above using underhanded tactics like taking a hostage to win against Kyojuro. Slasher was also rather petty, trying to find whatever means to provoke Kyojuro and growing further frustrated and more aggressive when the young man both held his ground, retorted back and even stopped his attacks.

Slasher was a bald, middle-aged man of muscular build and very pale skin that was of a light greenish-gray shade. His eyes had lime green irises, black scleras, and vertical slits for pupils, and he had sharp pointed nails that are dark blue in color, as well as prominent fangs in his mouth. Most notably, Slasher's whole body was covered in dark blue tattoos, running across various places on his face, limbs and torso. These tattoos light up and glow blue at moments of using his Blood Demon Art. He also wore a sleeveless blue shirt and black leggings complete with tabi socks and a pair of zōri with blue straps. Slasher was usually seen with a maniacal expression on his face.

Overall Abilities
The Slasher was a decently powerful demon, as evidenced by developing a Blood Demon Art and displaying skill in utilizing it for combat. He proved mildly troublesome for even a Hashira to handle, albeit most of it attributed to his penchant to use human shields. In terms of direct combat, the Slasher proved no match for the Flame Hashira.
