Demonslayer Short Stories

Spy (Yandere Douma x Reader)

Yuki was a low-rank demonslayer, not even a Tsuchinoe, and sent to investigate the Eternal Paradise Faith Cult with rumors of a demon there. Her mission was to infiltrate the cult and report back by crow, so she didn't have her uniform or her sword, just a plain black yukata, navy pants that were good for fighting in, and a violet haori. Hanging at her waist were two nichirin battle fans. The fans had small slits in them that were filled with Kocho's wisteria poison, which she could inject into a demon while fighting. They were also inconspicuous and could pass off as just an accessory. She'd trained with them for ages while preparing for this mission.

As she neared the building, she gripped her fans and studied the surroundings. She hid her crow, Burakkujemu, under her haori so she could relay information or call for help if needed. Other slayers on patrol had reported seeing a figure bringing injured and weak females into the cult, so Yuki had smeared dirt all over her yukata and slashed it a few times, giving it a tattered effect. Her hair was messy and filled with dirt from the journey, so she just needed one more thing to finish the disguise. Her least favorite part.

Yuki took a deep breath as she drew a fan, slashing it across her shoulder in one fluid motion. She winced and gritted her teeth against the pain. Tears leaked unbidden from her eyes as she cleaned the blade of her fan on her yukata and sat against a tree. The slice wasn't deep enough to knock her out, but definitely deep enough to attract any demon. She sighed and closed her eyes, evening out her breathing pattern and pretending to be asleep.

Sure enough, not even an hour later, Yuki could hear heavy footsteps coming her way. She almost flinched when she felt a cold hand on her shoulder. She could feel his breath on her shoulder, probably assessing the wound–or deciding whether he should eat her. She shivered involuntarily as the hands lifted her, not being careful with her shoulder whatsoever, and cradled her close to an ice-cold chest. She squeezed her eyes shut, shivering against the cold.

"Awww, are you cold, little one?" The demon cooed. A hand swept across her cheek and she quivered more violently. "It's okay, we'll be inside soon." A pause. "Wait, you can't hear me anyway. Well you are a beauty. Maybe I'll keep you." The demon started to walk. Keep me! The fuck your mean, 'keep me'?! I'll fucking kill you!

The demon brought her inside to what she thought was a small room. She was set on the bed, and could feel the shift in the covers where the demon sat next to her.

"Douma-dono." A high, nasally male voice said. "You have a meeting in four minutes. The demon, presumably Douma, sighed and patted Yuki's head.

"Take care of her when she wakes up." He said to the human. "I'll be back as soon as I can." The sound of footsteps and the door creaking could be heard, and Yuki almost breathed a sigh of relief.

The other human exhaled and walked to a corner of the room, and Yuki could hear the horrible sound of a chair dragging across the wooden boards. Might as well sleep; he doesn't seem like he's gonna try and kill me, she thought as her mine wandered off. Her mind slowed and dimmed as her consciousness faded.

~~***~~

Yuki's sleep was calm and dreamless. She awoke in a large bed surrounded by red curtains. A man was sitting at the foot of the bed, back facing her. He had long, platinum blonde hair woven into a messy braid. On top of his head was a design that looked like a blood splatter. He wore a skin-tight red long-sleeved shirt with a similar black splatter pattern on the upper half and beige hakama pants.

"Ah, you're awake." He turned to face her, and Yuki sucked in a breath. His eyes were a fractured spectrum of pastels. All the colors of the rainbow swirled through them, unsettling Yuki greatly.

But the worst part was his pupils. Instead of normal, circular human pupils, his chromatic eyes held the kanji for 'Upper Two'.

"What's wrong?" His face twisted into mock sympathy. "Are you alright?"

"Y-yes!" Yuki exclaimed, tearing her attention away from the numbers. "I'm fine, thank you. May I know your name?"

"I'm Douma." The demon smiled–fake–and placed his hand on her shoulder. Yuki recoiled. "What's your's?"

"Yuki." She responded curtly, quite proud of herself for not stuttering. "How did I get here?"

"I found you bleeding outside. You looked quite beaten up, so I decided to take you in." His smile just got wider.

"Ah. Well, thank you, but I have to go now." She started to get up, but Douma gripped her shoulder harder, eliciting a yelp. Shit! Am I gonna die here?!

"Please stay, at least until you get better. Your shoulder isn't fully healed, and you might get attacked by demons!" Douma said with mock concern. Fat fucking chance. I cant deal with other demons, just not a FUCKING UPPER RANK. AND UPPER TWO AT THAT.

"Thank you for your concern, but I really must leave." Again, she tried to get up, but Douma's eyes darkened, and his smile dropped for the first time in the conversation. Yuki noticed this and inched her hand closer to her fans just in case she had to fight. Douma's eyes darted towards the small movement, and he smirked slightly.

"Oh, dear, you don't really think you can beat me at tessenjutsu, do you?" That was all the invitation Yuki needed to grab her weapons and slash at Douma's neck. He lept backwards, a grin spreading on his pale face.

"Feisty." Douma drew his own two hidden fans with a flourish. The gold color flashed in the light as he brought one up to the face, covering his mouth. Yuki's eyes widened. Shit! No way I can beat him!

"Burakkujemu!" Yuki called. Her crow immediately flew out from under her haori. "Go find a Hashira!" He shot towards the nearest window, but Douma, with a swipe of a fan, trapped the bird in several vine-like ice sculptures.

"Well, we can't have you trying to warn the Corps, now can we?" Douma started to walk closer to Yuki, who stumbled back and tripped over the bed, falling backwards and landing on the cushions. As Doma drew closer, Yuki feinted to the left and slashed right, reaching to cut Douma. Just one cut. Just one cut, and he'll be poisoned. Her attempt succeeded, Douma blocking one fan but getting a minor slice from the other. Yes! Yuki could already see the purple spreading through his forearm, infecting his veins and working towards his heart.

"Hm.. poison huh?" Douma grinned, and without warning, ripped his arm off.

"No!" Yuki shrieked as his arm regenerated instantly. Douma moved suddenly, disappearing from Yuki's line of sight. She shook her head and stumbled back, crashing into a cold, hard torso. Cold arms wrapped around her waist as she shivered. "Let me go!" She tried to even her voice as she slashed helplessly at his arms. He knocked her fans out of her hands, summoning more ice-vines to wrap around her body. He let go and stepped in front of her.

"I thought this might happen.." Douma sighed, as though he were just disciplining a child rather than holding someone hostage.

"Let me go, demon!" Yuki screamed at him, straining against the icy bonds. He simply sighed again and waved his hand. The air around Yuki froze and crystallized, and as she inhaled, her limbs grew heavy and tired.

"You're staying with me forever, lotus." He chuckled as her mind dimmed and she slowly fell asleep in Douma's arms.
