Did Sesshoumaru and Inuyasha know their father?
Let’s start with Inuyasha first. We’ve heard Inuyasha mention something about how the last time he saw his father was when he was so young that he doesn’t even remember much of him. Additionally, his father had also passed away when Inuyasha was still just a small child. We’ve also seen clips of Inuyasha when he was a child with his mother at a house of some sort, so it’s a possibility that this house was where they resided as a family unless his father had abandoned his mother. All in all, I think it’s safe to say that Inuyasha did know his father though I don’t think he was on very personal terms with him. Sesshoumaru, on the other hand, I believe had a much closer relationship with his father. In fact, his father is the only person I’ve ever seen Sesshoumaru spoke of with respect. It seems he admires his father as a person and as a powerful youkai. You can often hear him say things in reference to his respect- they’re subtle but you can still denote the positive feelings he carries
