#dkbk demon DK x demon katsuki (male) and demon bk x fem human katsuki ( it's nothing deep they are just stupid)
___

Katsuki's life was going fine, she has a good academic record, annoying but good friends, beautiful face and body of a model and a bright future ahead. It was
2
Perfect until that weird creep suddenly appeared and followed her everywhere. That massive giant human looking thing with wings and horns just stayed glued to her side, watching her with expressions unknown due to that skull mask he kept all the time

Katsuki wanted to
3
Have a normal life, be back to her original life and there's one thing she needed to do

"What the fuck are you"

Confront her problem

That demon looking thingi beamed "kacchan! Finally you can see me"

"How the fuck do you know my name and why do you keep following me" katsuki
4
Barked, holding her heavy bag incase she needs to throw it and run for the door. It doesn't look like she can lock the thing here though

The demon finally took off his mask thingy, looking visibly annoyed. Katsuki wouldn't lie, he's adorable

" I told him it would mess
5
With your memory but he didn't listen! He never listens and now look what happened "

"What are you talking about?"

"It's a long story of you being idiot "

"What?"

So this demon, as he described himself,started telling katsuki some absurd things. He said katsuki was a
6
Reincarnation of his lover, demon katsuki Bakugou.

one day, katsuki just declared he wanted to start a family with Izuku, something he had seen humans do and desired to have it for himself. But demons don't get pregnant. They can't reproduce through an act of love
7
So katsuki started all this fucked up ritual to reincarnate himself on earth, as a human, get pregnant by Izuku and raise the child as their own.

"What the actual fuck" katsuki will not just believe whatever she hears

"I know! You were being stupid" Izuku shook his head
8
The entire thing is stupid. But kacchan wanted it, so Izuku had to give it to him

" You know we have to hurry"Izuku creeped towards her "if you can see me, it means you're regaining your power back.This body ain't strong enough to hold your soul, it will die and you'll turn back
9
To demon" katsuki was still processing all of this when Izuku pulled down her pants " how can I tell you're fertile?"

Katsuki screamed, slapping the demon right across the face " get away "

Izuku was stunned, holding his cheek. "Why did you hit me?" He couldn't believe it!
10
" don't fucking touch me"

Izuku looked like a sad puppy "are you mad at me?"

"WHAT THE FUCK DO YOU MEAN! YOU JUST PULLED DOWN MY PANTS"

Stupid demon pouted! Pouted!

"you don't remember me, but I promised....I get it.." he looked even more sad
11
" I get it's overwhelming for you so lemme say, you'll start seeing more demons around you, trapped souls and gateway, maybe then you'll believe me" he sat down in the corner of the corner

Katsuki rolled her eyes "get the fuck away from here"

"No" Izuku stayed firm
12
"I vowed to look after my love until my last breath"

Katsuki flopped down on bed, beyond annoyed

" Please tell me when can I impregnate you or kacchan will kill me"

"SHUT THE FUCK UP"

" We have less than an two year, please hurry"

"I'LL MURDER YOU"

___
13
Izuku got more annoying after that. Now that katsuki could see him, he /courted/ her as he had referred

"I did it once I can do it again" Izuku stood, a massive bouquet and a fox skull on his hands

Katsuki hummed, this is the most normal gift she had received from him in last
14
Weeks

"It's nice" she took it. A bouquet of tulip, the skull is nice too

"Can I impregnate you now?"

"No" katsuki ignored it "where did you get it"

"I stole those"

Ok, Izuku's idea of romance was different from her. Must be a demon thing

"Did you start seeing weird stuff?"
15
Actually katsuki infact had been seeing things she should not have, the demons, weird looking creatures, curses on people's back but for some reason everything runs at the sight of her. It makes her wonder if she's really the strong demon Izuku claims him to be, who just wanted
16
To have a family and went all means to get it.

"Tell me more about this katsuki bakugo of yours"

"You wanna know about my kacchan?"Izuku beamed "sure!" And Izuku kept going on and on about how amazing his lover is. Katsuki kept wondering, when she returned to her original self
17
will she lose her memory? Will the existence of human katsuki be erased? Was she fake? What was the point of her trying so hard then?

"And you know he had this massive sword-"

"Izuku"

"Yes?"

"Teach me how can I become the bakugo katsuki"

"Eh?But you are bakugo katsuki"
18
"I wish to be part of him. I don't wanna disappear or-"

"You wouldn't. You're him, just different body"

"Just teach me how to use my demonic power and I'll let you bang me"

"You just wanna be little shit to the whole world, don't ya"

" Just do it"
19
Izuku laughed, "whatever my kacchan says"

This is katsuki's journey, the road to become satan
