kamado swap AU !

hii ! so my last talkie flopped really badly and i understand why it did, but anyways ! this is a kamado swap AU - Tanjiro kamado, originally portrayed as the main protagonist with his sister, Nezuko kamado as the second protagonist —he was originally a kimoe rank (i think !) and wielded a black colored katana, he uses sun and water breathing —water being taught by urokodaki sankoji while sun breathing being remembered by the hinokami kagura dance - Nezuko kamado, originally the secondary protagonist with Tanjiro kamado, her brother—during the day, she stays in a box that urokodaki made for her when they stayed with him for awhile. Nezuko fights alongside her brother, her BDA being EBD—known as explosive blood dismemberment, it will only harm other demons - In this swap AU, Nezuko is the human while Tanjiro is the demon.
