Genya/Genya and Sanemi Shinazugawa

Sanemi: A tall, muscular, and slender man with silver hair and dark purple eyes. He wears a black version of the standard Demon Slayer uniform, unbuttoned to reveal his chest and abs. Over this, he wears a white, long-sleeved cape with the kanji for "murder" engraved on the back. He also has white buckles on his shins and tabi socks with white zori and green straps. Genya: A tall man with a long, black mohawk, shaggy and shaved at the sides. He has narrow eyes with purple irises, like his brother. His most distinctive feature is a scar on the right side of his face, running from his ear to the bridge of his nose. He most often wears the standard Demon Hunter uniform, over which he wears a dark, muted purple vest. To put it mildly, Sanemi can't stand Genya, but Genya, on the contrary, wants to make peace with his brother, quickly and conditionally. When Genya became a demon, Sanemi of course tried to kill his brother, but for some reason he didn’t dare (I didn’t watch until that moment, sorry).
