Aside from being a Hashira himself, he raised Giyuu (and Sabito). He made men out of them, put swords in their hands and produced the next Water Hashira, so the place he left behind wasn't going to be empty.

He raised Giyuu to be disciplined, calm, strong with a sword and without it, and sent him on his way when it was time. Gave him life lessons as well as battle lessons.

He accepted Tanjiro, made a man out of him, put a sword in his hand, taught him to survive and to fight. He taught him discipline as well, trained him to be a Hashira himself at one point, successfully securing the next two Water Hashiras in a row.

He protected Nezuko, took care of her for two years while also teaching Tanjiro, essentially caring for two children alone, one of them being a demon. Then, when duty called again, he showed up with no hesitation and no ceremony, no demand for anything, to care for Nezuko again.

And we all know why he was there. His real duty was to kill Nezuko should the demon slayers fail, so that Muzan doesn't find her. And he also accepted that duty, with no complaints, even if it would destroy him to see another one of his children die, especially by his own hand. But he sucked it up and showed up, ready to do what he has to do, if he has to do it.

All this AFTER he was strong enough as a Hashira to retire of old age.
