Demon slayer Academy-The last sun breather era.

This is my first story so if you guys found any mistake in it then I'm very sorry for that.
Reminding: I do not own KNY and it belong to Gotouge Koyoharu.

This story is about Tanjiro who is the eldest son of the Kamado family who use Sun breathing but no one know about it because they never use it in fighting and it has been passed down generation to generation which is know as Hinokami Dance. After his family died (just like manga), he and his sister-Nezuko (which was out and staying with her neighbor the time their family died) meet Giyu and he instruct them to his master-Former Water Hashira Urokodaki. Now their journey begin.
