Hinatsuru is a young woman of average height with a curvaceous yet slender figure, pale skin, and long black hair typically styled in a ponytail. Her large, almond-shaped violet eyes are framed by thin eyelashes and eyebrows, and a distinctive beauty mark under her left eye adds to her gentle and kind appearance. She is 21 years old and she is 5’4. Hinatsuru wears a short, sleeveless lavender dress with an irregular square pattern of a darker color, which has a plunging neckline that exposes her cleavage, and secured tight with a red-violet colored obi where she presumably stores her kunai. She wears brown fishnet socks that reach up to her mid-thigh along with light colored sandals with purple straps. In a flashback, she is also seen wearing long, fingerless fishnet gloves. Hinatsuru is kind, calm, nurturing, and honest, even when dealing with the antics of her co-wives towards each other. Despite only being slightly older than the two, Hinatsuru displays far more maturity and often acts to mediate situations between Makio and Suma, as seen when she spoke with Makio about Tengen and how he lives his life differently to that of traditional shinobi, despite Makio's confusion. Hinatsuru often serves as Tengen's emotional bolster in ways Makio and Suma cannot. Though generally serene and kind, she became truly angry with her co-wives fighting as their husband lay dying of Gyutaro's poison. She also expressed annoyance when Obanai Iguro demeaned Tengen for his efforts just to kill the weakest of the Upper Ranks. Like her co-wives, Hinatsuru has a soft spot for Tanjiro, due to his monumental aid in the battle in Yoshiwara, offering him kind words during his training and wishing the best for him in his battle against Muzan. She tends to favor Guest, the fourth wife. And her favorite food is anything Guest makes.

Suma is a young woman of short height with pale skin, shoulder-length black hair, short bangs, and blue eyes. Similar to the other wives of Tengen Uzui, she has a shapely figure. She’s the sensitive one.

Makio is a young woman of average height with a curvaceous figure, pale skin, and large light brown eyes framed by prominent eyelashes on both her upper and lower lids. Her thin eyebrows arch downward, giving her a determined and headstrong look. She has black hair tied up, with yellow bangs framing her face in loose, soft strands. She’s the hotheaded and aggressive one.

Tengen is a very tall, broad-shouldered, and incredibly muscular man with lightly-tanned skin and white hair. His hair is of an uneven length, the longest strands reaching his shoulders, and is styled with three more notable, shorter clumps arching up to fall as bangs between his eyes and on either side of his face. He has thin, dark fuchsia eyes that appear to slant inwards, each with one long eyelash flowing to the far side of his face. He also painted his fingernails and toenails with claret and bright green color. He is considered very attractive as noted by many women and even by Zenitsu; this has led him to use his looks as a tool for his missions whenever persuasion is necessary.
