Daki and Gyutaro (Yandere)

Gyutaro: Gyutaro is a tall man of fairly muscular build, with a pale gray complexion speckled with black blotches. His anatomy is quite strange in that his upper torso, arms, and legs are all defined with musculature, whereas his waist was incredibly skinny to the point of looking skeletal, with his pelvis jutting out at an unnatural angle. His spine is prominently visible through his back, and he is usually shown being hunched over. Gyutaro possesses thin eyes that were slanted drastically downwards at the sides, giving him a permanently haggard gaze. His miotic irises were green with a dark orange center, and his sclera was a bright yellow-orange with visible veins. The kanji for "Upper Rank" (上(じょう)弦 (げん), Jogen) is carved across his right eye, and the daiji for "Six" (陸(ろく), Roku) carved on his left. During his fight with the Demon Slayers, he lends his left eye to Daki and spends the rest of his battle with said eye shut, giving him a permanent wink.

Daki: Daki is a tall and curvaceous woman with lime green eyes with a dark orange center, long eyelashes, and very pale skin, complemented by neon pink lips. Her initially black hair is my styled in a full, long ponytail with kanzashi hairpins (three on each side on the top, and two on each side on the bottom) holding up the ponytail, along a small, golden comb on the back left side of her hair. The kanji for "Upper Rank" (上弦 (じょうげん), Jōgen) is engraved in Daki's left eye and the daiji for "Six" (陸(ろく), Roku) is engraved on the right. Her fingers ends in sharp, dark purple nails. She has a pink obi with black hexagon patterns on all of it, along with light grey blue flower with darker on the center and light orange three length lines on it wraps around her waist, used as her Blood Demon Art. Her toenails shares the same dark purple color as her fingernails. She sports two pink flower-like demon crests on her face and light purple on the center, one on her cheek and another on her forehead. She also wears a pinkish-red makeup on each sides of the corner of her eyelashes and eyes.
