Dark Knight is most likely a half-demon according to Evileye. Overlord was inspired by D&D as well, so it's very likely that he is actually a half-demon. Half-demons can almost be considered demihuman since they are not immortal, but neither are they human race. Heteromorphs are immortal.

Edit: Not all heteromorphs are immortal, like Nagas in New World which are considered Heteromorphs.
