Appearance:Himiko was a fair-skinned girl who was prone to blushing and was frequently described as having a pretty face. She had inward-tilting yellow eyes with thin slit-like irises, somewhat resembling those of a cat, and her wide mouth was also rather feline, as her canines were pointed and longer than the rest of her teeth, giving her a vampiric appearance. Her hair was a pale, ash-blonde color and was styled into two messy buns, with numerous wild strands sticking out, a straight fringe and two chin-length side bangs framed her face.

Clothes:Her usual outfit consisted of a plain seifuku with a Kansai collar, both the skirt and the shirt dark blue with a double white trim, which was paired with a red scarf that she tied loosely below. Over this, she wore an oversized beige cardigan with a long hem and cuffs, and pockets on either side, the right one was shown to hold a number of trinkets on either a keychain or a cellphone strap. She sported knee-length black socks and dark brown outdoor school shoes. She sometimes wore a tan pink duffel coat along with a pink scarf, the former was gifted to her by Skeptic after she damaged her old one in her fight against Curious.

Villain Outfit: In her villain attire, she wore the same outfit but with a few additional gadgets: a piped black mask, two green boxes of knives strapped around her thighs; a blue utility belt around her waist with more green boxes attached to it on either side. The most distinguishing feature was the loose black mask she wore around her neck, which was decorated with pieces of pale gray metal in the shape of a carnivorous grin. Three large silver canisters are attached to the sides of her mask; the needles poking out connected to the two larger cylinders strapped to the back of her belt, this is the mechanism Himiko used to suck people's blood for her Quirk.

Personality:an obsessive personality, disturbingly cheerful, unstable, manipulative and fascinated by blood. She is happy most of the time, a sadist in short..
