They're a whole different species from everything else you'd expect. Human, animal, etc, etc. [Leo waves his hand casually. As always he's happy to just talk. He has the gift of gab and he'll use it.] They live under New York in their own Hidden City. Their species is pretty small apparently. Far as I can tell, Drax only started mutating people to try and turn every human into a yokai.

Didn't exactly work, but points for effort, old man.
