Tanjiro was currently walking through the forest after completing his mission, with you inside the box he carried Nezuko in. You were currently sleeping, your head resting on Nezuko's shoulder.

He had found you a while back and since you never killed any humans, as well as the fact that you reminded him of Nezuko, he took you under his care about a year ago.

You were different from other demons. You didn’t need human blood to survive and the sun did not harm you. However, this also meant you were extremely weak as a demon. You were unable to gain strength in your sleep like Nezuko.
