''resurrecting men requires the restoration and maintenance of "the power to produce essence", so a semi-permanent supply of mana will be required, namely, a monster to copulate with the resurrected man as his partner and continue to provide mana.

That's when the other power imbued in a banshee's voice comes into play. Though melancholic, their beautiful wailing arouses carnal desire in men soon after resurrection when a man's capacity for thought is shaky, directing his unsettled consciousness at the banshee. Just as a man rises as an undead, he'll end up sexually assaulting the banshee wailing beside him. In other words, they offer their own bodies as a sacrifice to the men that they guide into undeath, and eternally continue comforting their husbands' souls with love and pleasure.''

It doesn't say that it has to be the banshee or even that it has to be a specific mamono, just that he needs a secondary supply of energy in the form of a mamono. It just so happens that most banshees "sacrifice" themselves to give the man his supply. In the end, all mamono infuse their husband with DE when they have sex.

As for why KC would have a mamono, who happens to essentially be a priestess to a god, assist a mans continued survival in matrimony with another mamono, well It's not the first time he's done it.

It would seem to me that if a man were married before the encounter with the banshee, then the his already existent wife would end up being his energy source, even if she had to monsterized to do it. If the man has a harem, then all of the mamono in that harem would be fueling him.
