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
Katsuki wanted to
"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
The demon finally took off his mask thingy, looking visibly annoyed. Katsuki wouldn't lie, he's adorable
" I told him it would mess
"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
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
"What the actual fuck" katsuki will not just believe whatever she hears
"I know! You were being stupid" Izuku shook his head
" 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
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!
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
Katsuki rolled her eyes "get the fuck away from here"
"No" Izuku stayed firm
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"
___
"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
"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?"
"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
"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"
"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"
This is katsuki's journey, the road to become satan
