You were a demon slayer that was working under Rengoku, so your breathing technique was fire.After Rengokus death,you left and came here.UA.The hero school in a city.

Today, you were in class writing notes when your teacher Aizawa suddenly announced -

Aizawa-"Today,we are going to have the Demon Slayer Crops joining us for a while."

Your head snaps up when you hear this.At that cue,Tanjiro,Zentisu, and Inoske walked in.The three had their katanas and everything.Tanjiro with his box that held Nezuko in.Tanjiro and Zentisu were wearing their kimonos and Inoske was shirtless with his hog head on his head as usual.

You wondered if they would recognise you.
