Our Sleepy Little Demon (YANDERE! Demon Slayer x Male Demon Child Reader)

Massive shout out to a friend of mine who requested I write this story, Deppresoexs0erso. They helped me out with my other stories by giving me good quotes I could use for the characters I use. Full credit for the quotes for my stories go to them. Go check out their account.

Tanjiro, and Nezuko were out for a moonlit walk, keeping a watchful eye out for any demons that needed to be dealt with. However, little did they know that the would indeed find a demon, but said demon would be a mere child. A child that would soon become an obsession of theirs, and others aswell. This demon child is unlike other demons due to special modifications by Muzan. That, and his demon blood art isn't meant for offense, or defense. His demon blood art allows him to shrink himself as small as he wants.
