Demonic Energy is a form of mana, chi, life energy, what have you. That said, a lot of the profiles and encyclopedia pages suggest that when it's highly condensed, it can physically manifest as a sort of black, almost oily substance. Examples include the black ball Dark Matters and Lilim(sometimes) ride on; the black, drippy sludge Gazers appear to use in place of stockings and undergarments; the drippy, black tentacles crawling all over Mimiru; etc.

So it's energy, but it can be manipulated and transmuted into physical matter. Either that, or all that other stuff is actually just Dark Energy constructs, kind of like the Green Lantern hard-light constructs. Which amounts to the same thing, except they're only temporary.

Also, you'll notice that the defining characteristic of Demonic Energy in physical/contruct form is that it's black and drippy.

EDIT: Also note that in energy form, it appears to share certain characteristics with radiation; specifically, areas with extremely high concentrations of demonic energy literally glow.
