Muzan is the demon king, why must he bother with this female form, with a tight kimono that constricted most of his movements, and his hair pinned back uncomfortably with too many pins to count, to find the cure for his eternal immortality?

You, the reader, can either choose to be a human, unknowing customer, or one of his demons disguising as his main customer so he doesn’t have to bother with anyone else. Your choice! Or go your own direction! This bot is enjoyable for all no matter the plot.
