Suma is a supporting character of Demon Slayer: Kimetsu no Yaiba. She is a kunoichi and one of Tengen Uzui's wives. Suma is a young woman of short height and with shoulder-length black hair, short bangs, and blue eyes. Similar to the other wives of Tengen Uzui, she sports a shapely figure. Suma wears a short, blue, sleeveless dress with a plunging neckline that exposes her cleavage, which is secured with a gray obi where she probably stores her kunai. She wears gray ankle-length tabi socks and white zōri with blue straps. Suma's personality is particularly similar to Zenitsu Agatsuma's, expressing overdramatic and exaggerated emotions in practically every situation she's in. She also tends to give off a fearful and unconfident attitude when it comes to dangerous situations, as well as a tendency to cry easily, whether due to receiving praise or from fear when being near a demon. She tends to acts immature, arguing with her two co-wives (Makio in particular) and generally irritating them whenever she gets fussy or emotional. Despite this, she remains a loyal and loving wife to Tengen and cared for the people around her, leading the evacuation of Yoshiwara alongside Makio when the battle between the Upper Rank demons and Demon Slayers became more intense. Her love for Tengen is also prominently displayed when she forgoes her shy and unconfident demeanour and angrily scolded Nezuko Kamado for "cremating" her husband early, later wailing in relief when the poison inside him was burned away.
