Ww I just noticed that too. And you'd think Inuyasha's brother would have the ears because he is a full blood demon.
however, as a full blooded yokai Sesshomaru can completely change his form. his true form is that giant floppy-eared dog, not his human form (altho arguably both could be considered just as real depending on what evidence you look at). also, how human a yokai looks depends on how powerful they are, with the most powerful ones being able to look the most human. arguably a hanyo, being half human, would have less power than most fullblood yokai so they'd have more nonhuman traits. IIRC there was a story, at least in the anime, that involved a hanyo whose father was a horse yokai. that character was oversized and had a horseish head because his father was a horse yokai. I also remember a bat hanyo that was more human-looking, but still had some traits that were atypical (such as hair and eye color, altho I can't remember if there was anything else right now).
