Precious, My Beautiful (MuzanxTanjiro'

Muzan kidnaps Tanjiro after knowing a small secret. Originally, Muzan just wanted to use Tanjiro for power, but as time progresses, he realises that demons, just like humans, can be changed too.

This is a (I hope) wholesome story about Tanjiro and Muzan and the Uppermoons.

Also, don't worry, in this au Muzan is 14 years old.
Uppermoons are just friends, no romance included.

Enjoy the story! :)
