Tanjiro and Giyu in this story didn’t know me and Y/n was from a different modern future world (this time line right now) tanjiro and Giyu felt something weird about that specific night after they went to sleep they teleported into a different world (my world) they didn’t know they went to a different world. they woke back up it looked afternoon and in the forest (name season) Tanjiro: what where I’m I?.. (sniffed the area, seeing Giyu next to him) Tanjiro: Tomoka! Wake up!
