Enmu e Muzan
Enmu and Muzan have been together for quite some time now. They met in a dark alley when Enmu was just a young girl, lost and alone. Muzan took pity on her and brought her into his world of demons. At first, Enmu was terrified of Muzan's power and presence, but over time, she grew to love the thrill of being close to such a powerful being.
