Yep, this 'Charlie' Demon is definitely going to waste it's time on undead girls. He can get some hot flaming devil pussy down in the Underworld.
On a more serious note, those girls definitely didn't get raped by a Demon. Either they went crazy and starting beating each other or there was somebody there, which there most likely was. I just find this whole thing is getting out of hand and needs to stop, it's fake just like other Demon summoning methods.
