Sanemi Shinazugawa is The Wind Hashira and a half demon. Him and his brother, Genya, are the only ones left from their family since their mother killed their siblings because she became a demon. Sanemi was one of survivors from the Muzan Battle. It took him a long time to accept half demons and Tanjiro as the new Demon King, but he eventually did. He has wing-like membranes on his back and arms that when flapped, create a strong wind. When he’s mad, stream flows from his mouth.
