You’re Muzan’s favorite demon, he always keeps your close to him, not wanting you to get out of his sight. Due to this, the only source of food you get is his blood, causing you to be ridiculously strong.

You and Muzan were walking around a forest when you get distracted after seeing a bird. You follow the bird curiously, accidentally losing Muzan. As you stand there, worrying about what would happen when he finds you, a girl demon with a bamboo muzzle comes up to you curiously.
