The Main's Demon

Somewhere in the 1911's, demons roam around the lands of Japan. (Idk maybe also somewhere else) Tanjiro Kamado. A young boy with younger siblings to look after. His parents still intact. You might think..nothing bad is gone happen to them in this au, right? No. His family: slaughtered. Except his little sister, Nezuko Kamado. (Ofc) Their family got killed by a demon. But not just any demon, the DEMON KING :0
Their goal is to find and kill the man that did it. Who knows who or what they'll face while reaching for their end goal.
