If I'm right, the Sun Breathing Style was the first ever style to br created, and all the other different style came from the Sun breathing Style. Also did u see the earing that Tanjiro was wearing. It shows a sun in it. So does that mean Tanjiro's family were the creator of the Sun Breathing in some sort, or have a relationship with the Sun Breathing. Also I think the Sun breathing was past down in Tanjiro's family for generations.
As a manga reader, I know what will happen in the Demon Train Arc, so I'm 100% sure I'll cry + the animation ufotable will make for it is going to kill me even more.
