Kimetsu No Yaiba x Reader ! {Oneshots}

By Your Side//Rui

Rui thought he'd lose everything as a demon.

He was stupid to believe that they were made up; that they were monsters created to scare children into staying in bed. He missed the times he could laugh in ignorant bliss at the people who were so paranoid about them.

'Guess he could never have the last laugh.

It has been almost a week since he had murdered his family. He still couldn't shake off the trauma he felt from staring at his loved ones in cold blood.

The young demon trembled all over as he curled into a quiet, sobbing ball deep in the forest.

What was worse? He was given the responsibility of being "A 12 Moon Demon." He didn't want that at all. He didn't want power.

I just want to see my family again.

Suddenly, footsteps.

Rui gasped. What if it was a demon slayer?! He rushed into the safety of a tree branch, hugging the trunk to his chest.

"Rui?!" A voice called out from below.

Y/N?

That was his best friend from the village.

Rui nearly fell off the branch from relief and joy. Out of all people, he knew it was her he needed to see at this time.

"Y/N-chan!"  Rui cried, jumping off his hiding spot and embracing her tightly.

Y/N fell to the ground in fear and terror. Something was on top of her! Was it an animal? WAS IT A DEMON?!

"WAHHH!! GET OFF GET OFF GET OFF!!!"

"Do you not recognize me?"  Rui whispered desperately.

She felt something wet run down her neck, along with the strange creature trembling as it gave her a tight hug. Y/N was just as shaky as she tried to take in what had landed on her.

It wore pure white garments, its skin pale and cold. And it's hair...

..wait, isn't that his hair?

But why was it pink?

"Rui, is that really you?" Y/N croaked out.

The creature pulled away, sniffling. It's eyes were closed as he rubbed them hastily with an arm. So that was why she felt something wet. He had been crying on her shoulder.

It looked exactly like Rui. That was, until...

...he opened his eyes.

They were a deathly shade of black. Those of a demon.

Y/N stumbled backwards in fear. So it was  true. He had  turned into one of them!

"I'm so glad you're here!"

Y/N stiffened at his words. She assumed he had lost his humanity, and that she'd be eaten on the spot.

But behind his eyes, there was a genuine luster of happiness.

Y/N tried to relax her beating heart. Rui looked completely different, but he was still the same boy she had come to befriend.

"S-sorry for hugging you like that..." Rui stammered. "Especially in the state I'm in."

Y/N was trembling all over. It was painful to look at him like this. Teary-eyed, clearly still fazed by the heavy incident.

I have to get out of here fast.

Rui watched in horror as Y/N suddenly whirled around, disappearing into the bushes she had appeared from.

He tried to go after her, but he knew it was too late. Why did he have that stupid spark of hope, anyway? He was a demon. Of course she wouldn't want to be with him anymore.

But my only family...

He felt relieved tears welling into bitter ones. He slowly got up, turning to walk away.

The bushes rustled again.

Rui peered over his shoulder in surprise.

Y/N stood there, looking dishevelled. She looked as if she returned from somewhere. She panted heavily as she carried what looked like essentials for a camping trip. A medicine kit. Food. Two futons.

Wait... two?

"I'm staying by your side for the night!" Y/N called out through her exhausted take of breaths.

"I need to treat you. What happened to you?! It must be so hard being a demon! Are you hurt? Are you hungry? It's been almost a week..."

Rui stood breathless at her determination, his eyes wide.

"But if you stay... aren't you afraid of getting hurt?"

"I'm staying by your side for the night!"  Y/N repeated firmly.

"Y/N..." Rui weakly spluttered.

"Yes?"

"...may I hug you again?"
