Kiheki is a blue-skinned oni. Her hair is white and tied in a braid, which is styled in a Hime cut, and tied with a red ribbon. Compared to Kiku, she only has one horn, which sits on the right side of her forehead. She wears a beige sweater vest over a white dress shirt with a red bow at her collar. She also wears a dark gray skirt, knee-high black socks, and dark red loafers. Her eyes are half-lidded and have small irises. She is also sometimes shown with her hair tied up into a ponytail.
She wields a black kanabō (spiked iron club), which has a blue gradient to it, with a bandaged hilt and a grip handle at the end. The Kabanō has a claw-like appearance at end of the club, with four digits, possessing a single blue eye at the centre of its palm.
