They can't. But Demonic Energy is just the translated term for what is essentially "A Monster's Specific Variant of Spirit Energy". The original Japanese doesn't discriminate between the two terms and just calls them both the same thing, so I've heard.

Anyway, the point is that Incubi can feed on Mamono's DE just as much as Mamono can feed on Human's SE.
