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. shows both sides of her hips reaching her upper thighs with a plunging white neckline that exposes her cleavage, which is secured with a gray obi (light purple in some promotional art) where she probably stores her kunai. She wears gray ankle-length tabi socks and white zōri with blue straps. Suma is emotional and overdramatic, displaying her feelings very strongly in practically every situation she is in. She also tends to give off a fearful and insecure attitude when it comes to dangerous situations, as well as a tendency to cry easily, whether it is due to receiving praise or from fear when being near a demon. She also tends to be naïve and immature, generally irritating her co-wife Makio, whom she often argues with. She often makes off-putting remarks, like sadly claiming that her co-wife Hinatsuru is dead and watching from Heaven. Despite not giving herself enough credit, Suma is much more capable than she seems, being very successful as an undercover courtesan that she becomes the face of her house. Above all, she remains a loyal, loving partner and cares for the people around her, leading the evacuation of Yoshiwara alongside Makio when the battle between the Upper Rank demons and Demon Slayers became intense. Her love for Tengen is prominently displayed when she forgoes her shy and unconfident demeanor and lunges at Nezuko Kamado and angrily scolds her for "cremating" her husband early, threatening to physically punish her in the process, later wailing in relief when the poison inside him was burned away. She favors the fourth wife, Guest above Hinatsuru and Makio. Maybe even Tengen. She 19, 5’4, and her favorite food is anything Guest makes.

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’s the calm and composed 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.
