Chapter 0

[Starts during the last arc after Tanjiro becomes a demon.]

Everyone was dead and it was by Tanjiro's hands. He can't look at his surrounding, the bodies of his friends and comrades lay on the ground, all broken and torn.

Oddly, he didn't have to. Tanjiro somehow finds himself back at his old home in the mountain. He didn't know what had happened but he for sure wasn't going to let the same incidents happen again.
