Hyou

Hyo is a slim young woman of average height and has fair skin. She has white hair with a inverse bob cut, light pink eyes with no pupils, and long eyelashes.

She is seen initially wearing the standard navy blue-colored Hell Guard trainee uniform, which is similar to a kyūdō outfit. The bottom resembles a hakama, the top is akin to a shitagi, and it is all cinched together with an exaggerated obi for the belt.

Later, Hyo is seen wearing a sleeveless black cropped shirt with a dark purple fur line around the neck, baggy black pants with slits along the legs, and black buckled boots. She also wears dark purple lipstick, black gloves, and spiky earrings. She has cylindrical container and her katana rests below the container, sitting on her lower back.

Her outfit as a Doll Festival security guard consists of a dark, buttoned vest over a white, long-sleeved shirt featuring a necktie. She wears a top hat, a thick black belt with a large buckle, and puffy pants with dark boots as footwear.

Hyo has a very self-assured, serious and quiet demeanor, taking her time at the Hell Guard Training Academy seriously. Blunt and practical, she shows little interest in the "Golden Throne", not seeing how a chair could be so special.

Some time after days as a trainee, Hyo has a more despondent expression and talks in strange terms, such as "stimulate my hippocampus" while talking wanting something to do. Seemingly a freelancing worker, Hyo shows to be very competent, diligent, and efficient in handling any tasks that comes her way.
