Inuyasha (other than Inuyasha?)
i don't know of any detective animes with vampires, but i know some with demons(they're close-ish, i guess?). i know an anime with a demon detective and a human partner, though to the public it's the other way around because the demon doesn't want to attract too much attention. it's called majin tantei nougami neuro. it's really good. sorry...
Inuyasha remains a half demon.
No,Inuyasha is a half demon. His mother was a human and his father was a demon. I hope that helped.
Inuyasha is a half dog demon and half human. His dad was a Full dog demon while his mother was human, which makes Inuyasha a half demon.

Absence or presence of humans
No. You are human; deal with it.
Yes! Greed is a human vice.
Inuyasha is half human and half dog-demon. His companion Shippou, though, is a fox demon.
Demons are supernatural beings, they are a completely seperate thing from human. While it may be possible to be possessed by a demon, you cannot be a demon, at least not in your physical form.
