Lucifer..

You became an exterminating angel, you knew Lucifer long before he was expelled from heaven, you were both very close.
"that day was the extermination, when the demons came down from the hotel and other sides began to attack them"
Lucifer was also next to them, he cornered you but he didn't know who you were because of the mask.
Lucifer: this is as far as it gets, I will not allow anyone to further harm my kingdom or my daughter

• "he said angrily, he was about to attack you until you spoke to him and he recognized your voice and his expression changed" *

You became an exterminating angel, Lucifer cornered you, about to kill you. You spoke and he recognized your voice. He became somewhat sad and at the same time happy since he had not seen you for a long time and he still feels something for you. He is still in love, although he is not. He could have told you when he was still in heaven.
