This story begins with young Millie being told a legend as a bed time story, about Y/N, The Calamity Demon. Many years later when Millie and her co-workers are captured by humans, she is saved by the demon she learned about in her childhood. How wil...
You arrive back home and open the door, you see Millie on the couch to the living room watching TV. She was watching Baki Hanma on Helflix, it was an anime that the both of you watched together. However, you had already watched the entire thing long before you met Millie so she knew you wouldn't mind if she continued to watch it while you weren't with her. You walked up behind her and kissed the top of her head. She smiled as she paused the show and looked up at you.
"How did it go baby?" Millie asked with a curious smile.
"It went well most if not all of my old friend are in and will be their on our wedding day my love" You tell her.
"That's wonderful baby, we should go to bed" Millie said as she stood up and extended out her hand to you. You took her hand and she lead you back to the bedroom. You went into the bathroom and brushed your teeth and went to the toilet. You exit the bathroom and see Millie who is patiently waiting for you on the bed. You hop into bed with her and you both start cuddling. You both fall into a deep sleep.
The next morning you awaken with Millie sleeping peacefully by your side. You get up and make yourself and Millie breakfast which was scrambled eggs on toast with the bacon of a hell pig. You set down your plate at your seat and begun devouring the meal you had cooked. As you finished you heard the door to the bedroom creak open which revealed Millie. She rubbed the sleep out of her eyes, her black singlet was crinkled, one of the straps falling off her shoulder. She walked up to you groggily and rested her head on your chest, you smiled and gave her a kiss on her head.
"The food is ready my love, eat, you'll need your energy for our spar" You say, Millie immediately woke up as she heard about her sparring match with you.
"How could I forget!" she exclaimed, she quickly ate her food in thirty seconds leaving you dumbfounded. "So can we start it now?" She asked, you were still processing that fact at how fast she ate her food before you shook your head, regaining your senses.
"Let's start it in an hour, give you time to warm up" You say. She nods in agreement and rushes into her bedroom to get changed into her usual attire, she runs outside and begins warming up. You make a coffee and drink it quickly before you also change into a black singlet and loose shorts. You open the door and exit leaving the door open. Millie stared at you with determined eyes. You grab her and teleport in the middle of a baron desert, here you both could spar as much you want without risking the destruction of your house or risking anything else getting damaged. You both take a few jumps back. Millie assumes a fighting stance while you put your hands in your pockets.
"Now I will fight you as if I was fighting an Imp in the street, I will simply dodge and taunt you, let's see if you can land a hit... babe" You say, already beginning to taunt her as you leer at her. Millie of course bit into it. She immediately charged forward attempting to kick you, you dodged. She then through a flurry of punches, you dodged each one. Just before she could throw a left hook you swept her foot. She fell but used her hands to bounce herself up, the sudden reaction was something you hadn't expected. Just as she was about to throw a fly kick she sees your eyes. Your eyes shook slightly as you stared at her, your gaze felt like she was piercing through her soul. You extend your hand out, a shockwave emits from your palm, knocking her back a few feet. You made sure to control yourself that way she wasn't sent flying. She lands on her feet and begun running at you again. You stomped your foot on the ground, earth pillars rose up from the ground in Millie's direction.
"Come on Y/N stop holding back... unless your scared" Millie said as effortlessly dodged his earth attack. Your hand stiffens as the insult for some reason got to you. You manifest a couple dozen knives and send them flying at Millie, who deflects them with minimal difficulty.
"That's all you got?" She asked as she landed a few hundred feet away from you. You decide fine, you should go into your second form which you had been training in secret. You close your eyes and let the darkness consume you. The darkness created clothes over you that resembled rags. (as shown below)

you again grew slightly more muscular, and your eyes glowed a blood red. Compared to the last time you had used this in front of Millie you much stronger as you had much more control. You lean forward slightly staring at Millie before you launched yourself at her. You covered the distance between you and her in mere moments.
"He's even faster know" she thought as she through the strongest punch she could muster, as she through it you moved behind her, she jumped back turning around but you were already in her. That look appeared in your eyes again...
Fear
That was all she felt as in slow motion she his fist coming towards her, however she felt her foot touch the ground, she used that jump away. She saw as Y/n swiped his fist down, punching the ground. The crater that was formed was massive as Millie lost her footing. She covered her face to protect herself from any falling debris. As she blinked for a moment there were in front of her swiping away debris that was about to fall on her.
"And I was supposed to be the one taunting you, you ended up doing my job for me" You say with a small smile as you rub the back of your head, turning around to face her. Millie punched you light in the side of your arm.
"Damn babe you've been holding back a lot from me" Millie said.
"Just don't wanna accidentally hurt you" You said, although if you were being honest you were more afraid of killing her.
"Yeah maybe you should hold back that in our sparring sessions, but on our wedding night I expect you to use that form in a... different activity" Millie said.
Oh how this girl could make your mind wander. You watch her as she walks around and looks back at you.
"Uhh baby... where are we?" She asked as she looked around not having a clue where the two of you were.
"Oh right!" You say as you walk over to her and put a hand on her shoulder and teleport yourselves in front of your house. You open the door for her and let her in which causes her to give a small giggle.
"C'mere you big goof, lets watch more Baki together" She says as she lays on the couch and gets Helfix ready.
"Sure thing babe" You say as you sit on the couch and lay on her. You both watch a few episodes of Baki and then you realize something.
"Ugh we have to go back to work tomorrow" You groan and Millie giggles at your slightly childish reaction.
"Yeah we do baby, oh! I almost forgot! I need you to take me to my old apartment, there is some stuff there I would like to bring over if that's ok?" Millie asked.
"Of course, now we can make you moving in more official instead of you spending most of your time here" You say cheerfully, the thought of you and Millie living together exciting you. You teleport her to her old apartment and you both agree on moving the stuff she would like moved after work tomorrow. With that you both gave each other a good night kiss and hug and said your goodbyes and I love you's. With that you teleported back home and jumped into bed, you couldn't wait for tomorrow.
