Actually K'eth DE is monster energy not succubus energy. It gets to be controlled by the Demon Lord, but is not dependent on them.

"In the age of the  former Demon Lord, these energies remained with their respective species, but the  current Demon Lord has forced her own  succubus demonic energy into  every species. This is why the monsters are now monster girls, with curvy female bodies, sky-high lusts, and the ability (or requirement) to use semen as a dietary staple."
