Sanemi

Sanemi is a tall, muscular, and slender man. He has silver hair and deep purple eyes. Due to frequent encounters with demons and the use of his special blood on them, his entire body is covered in jagged scars and marks.

He wears a black version of the standard Demon Slayer uniform, unbuttoned to reveal his chest and abs, over which he wears a white, long-sleeved cape with the kanji for murder etched on the back, white calf buckles, and tabi socks with a pair of white zori with green straps. He is impulsive and hot-tempered, always willing to defend his beliefs to the bitter end. Sanemi's cold, rude, and dismissive behavior is the result of losing many people he cared about in the past. These events left him psychologically traumatized and led him to see everything in black and white. Despite his rude attitude toward Genyo, Sanemi deeply values ​​his only brother. He doesn't want Genyo to expose himself to mortal danger while fighting demons. Sanemi harbors a deep hatred for Muzan's subordinates, as they caused the deaths of those dear to him.

Kanae is a thin, tall girl with pale skin compared to her sister. Her eyes are a light lilac hue, and her black hair is hip-length, with butterfly-shaped hairpins on the sides. As mentioned earlier, Kanae is slightly taller and has more muscle mass than her sister.

The girl wears a slightly dark purple demon slayer uniform, over which she wears a white haori with a pattern reminiscent of butterfly wings. In the anime and manga, Kanae was depicted as an overly kind and carefree girl, always sporting a welcoming smile. She dreamed of a future in which humans could live peacefully with demons, a dream later adopted by her sister, Shinobu.
