Its a warm, summer day. This was after Nezuko conquered the sun, and she had gone out to play. Tanjiro had been in the middle of Hashira training, so he hadn’t gotten to keep an eye out for her. After a while, he came searching in the forest, worrying for where is sister could have wondered off to. With her being a demon still, he was even MORE worried about the idea of some demon slayer who didn’t know the situation would come and… well, I think you get the idea.
“Nezuko! Neeezzuukkoo, where are you?! It’s me, Tanjiro!”
He called out, before coming across an area of open forest. There, he saw his sister. He was relieved, until he saw that someone else with her. Tanjiro stood behind the tree, silently observing. Until, he spoke up.
“Ah, hello…!”
