Demon Slayer X Reader Oneshots

Shinobu x (Demon!) Reader

Requested by @PillowWillowTree :)

     Loneliness. Sadness. Emptiness.

     These were the only emotions you ever felt.

     You were positive that you had felt the same way back when you were a human. You were positive you were just an empty shell of a being.

     But alas, it didn't matter. You had only one purpose; to serve you master, Muzan Kibutsuji.

     You ran through the dense thicket that made up the forest, killing demon slayers who had come for your head. It was almost laughable, to you at least, how weak the slayers were compared to you.

     After killing a whole crew of demon slayers, you were sure that there were none left. You looked at the bloody massacre you had created, however, you felt no remorse or guilt at the scene. You didn't feel anything, even after claiming so many lives. Everything just felt numb, as always.

     You jumped from tree to tree, trying to locate the small, run-down shed you'd been staying in. After spotting the rickety old building, you hopped down from the tall cedar tree you were perched upon.

     Other demons actively sought out humans to kill and devour, but you were fine with feasting on the occasional traveler who dared to wander into your forest. As you neared the entrance of your shed, you noticed foreign footprints on the dusty dirt path by the door of the small building. Upon closer inspection, you realized that the door was open. You'd never leave the door open.

     As you cautiously approached the shed, a soft hand suddenly landed on your shoulder.

     You jumped back immediately, your reflexes on high alert. However, your guard fell as you saw the girl in front of you.

     She had her hair tied back with a butterfly pin holding together the hairdo. She had long bangs that adorned the side of her face, which beautifully faded into a lovely purple color, the same color as her eyes. Her butterfly haori draped over her small form. Though she was clearly in danger, her beautiful face wore a gentle smile.

Ba-dum.

     Your eyes widened. Was that your heart?

     You began to feel a feeling you've never felt before. It was strange, but at the same time, enlightening. You felt giddy, and your heart felt fast.

     'Is this what humans call 'love'?' It felt so foreign, yet familiar to you. Perhaps you've felt this in your life as a human?

     "Hello there." The mysterious girl started. "I am Kocho Shinobu, the insect Hashira. Unfortunately, I am here to slay you." Despite saying such dark words, her smiled was the same, making you feel all the giddier.

     You couldn't let her kill you, but you couldn't bring yourself to kill her either. You wanted to explore this new feeling. You no longer wanted to just be lonely and empty.

     Within the blink of an eye, you were behind Shinobu. You placed your hand on the back of her head.

"Blood Demon Art:"

     Shinobu's smile disappeared and her eyes widened in fear. She couldn't do anything. She was too slow to react.

"Corruption of the mind."

     Suddenly, Shinobu fainted. You picked up her limp body and walked back to your shed.

———

     You watched Shinobu sleep for hours, just waiting for her to wake up. Your heart fluttered the entire time. You watched as her chest gently would gently rise from her breathing. You adored how serene she looked in her sleep.
