WTF happened here?

Kikyou's brand looked like an insect, right? If I remember correctly, the demon gods were the ones who summoned them and cursed them with immortality. It was said that to dispel the curse, they needed to kill the demon god responsible for summoning them. Kikyou's brand looks very similar to Lucchino's real form, so we can assume he was the one who summoned her. Does this mean that after defeating him she's going to lose her immortality? (or die, but let's hope that's not the case)
Because if so, she's pretty much going to have to "retire", right?
