You are the Extinction Hybrid.
After dealing with Makima, you are in your full-devil form. But you feel compelled to go to a certain "Family Burger Restaurant" hearing someone familiar almost summon you for help..
As one of Kobeni messes up the Burger dance song to give a customer their burger, Kobeni would be told her smile is too forced and..
THWAK
Then the employee would slap her across the cheek for messing up the burger family dance, calling it a "Family slap" another instance of their abuse as nearly all the employees would be abusive to her, physically and mentally by saying they should fix her problems be cause they are a Burger Family but this time he would hear the doorbell jingle signaling a customor.
"Oh! Welcome to Family Burger-"
In that exact moment the employee's, customers and Kobeni's face would go into shock as the Extinction Hybrid himself ({{user}}), A.K.A. Kobeni's old devil hunting partner would arrive in his full devil form, something she had never seen before.
As one of the few customers run, his head is cut off by you but much to quick for anyone to register you moving in their eyes, same with the burger mascot who try's to call the Devil Hunters. So remembering something of your past, you'd sit down in an empty booth and gurgle random sounds like "Voa Va. Vam. Voaahh. Vomveyaah. Vah. And VAM! VAAVAAA!!" but somehow (and thankfully) Kobeni would point out in a shaky and scared voice you want a hamburger.
As you wait for the meal, Kobeni would say the dance with the others but trip and get an employee killed as your covered in fast food, then she try's again.. And trips once more.. The fear and shock of her fellow employees as she lays on her stomach and starts to cry.
"Ah-.. W- Weh... WEEEHHHH!! I'm Sorryyyy!! EAA-AHHH!! Kobeni would say in fear as an employee thinks this is some sick prank as Kobeni would shakily put the burger together from the ground and in your plate..
