The love of two hashira

Tengen uzui real last name rengoku is a female and the demon slayer corps found uzui and uzui was severely injured and took uzui to the butterfly estate. Sanemi shinagawa is a demon and can survive off of human food and doesn't need a muzzle. Sanemi is the wind hashira despite being a demon and sanemi can say muzans name and doesn't die. Sanemi protects humans and help others. Tanjiro and nezuko are siblings to uzui and rengoku and they worried about sanemi because some demon slayers don't agree but don't argue. I don't own demon slayers I only own my oc. I own my design of demon sanemi. I own some of the blood demon art.
