So I'm guessing Yorichi spent his remaining years searching for his brother after he became a demon, which would explain why when Tanjiro's ancestor mentioned about Yorichi settling down he rejected that idea. You could say Yorichi's will to find his brother who had become a demon, kept him alive to old age considering those with the mark dies early. Also the demon brother didn't understand Yorichi even to and after Yorichi's death, he never stopped and tried to understand at all. He just kept wallowing in his own jealousy towards Yorichi and his abilities, but it's also sad too because he never stopped to appreciate what he had or the brother who loved him.
It's so sad that Enki died, I think he would have made a great addition to the main cast and he would have been a great help with going after Elf and this mysterious organization.
Thatll make things easier for them, and as you read this from the first chapter everyone seems laid back and having difficult stuff for them to solve is part of their character growth, especially jyugo
I'm dying to see how they're going to handle the snu snu between these two, considering that in the novel Hugo and Lucia get it on very frequently and it's very descriptive
