The breath of the sun user is NOT FROM TANJIROU'S FAMILY. He is just a friend of Tanjirou's accestor. As mentioned in the manga, he has no successor for the breath. Henceforth, in order for Tanjirou's ancesstor to repay the dept for saving him and his wife he will help him in passing down the Breath of the sun as a Dance until a worthy user is born(I'll assume it is tanjirou) as he was not capable of learning the breath.
