The corners of the boys' lips twitched upwards curling into a warm smile as the young girls head laid leisurely on his shoulder, her hands hugging the haori close to her body the sound of snow crunched under their feet "Are you still cold?" The boy asked in a caring tone wrapping a frail arm around the girl pulling her into his chest.

The girl smiled warmly her (E/C) orbs stared deeply into his burgundy eyes a familiar warmth washing over her, "No." she replied simply a small smile on her face as she stared at the ground shyly blushing as she felt the boy brush a stray strand of hair behind her ear.

The young girl perked up as the eldest Kamado son came to a sudden halt his heels digging into the snow below their feet "is something wrong?" (Y/N) asked inquisitively cocking an eyebrow, "I smell...blood." Her (E/C) eyes widened in horror as they began to sprint up the mountain the cold air burned their lungs the cold wind stinging their faces,

(Y/N) eyes carefully surveyed the surrounding trees a sense of dread washing over her eyes widened as she saw a shadow among the trees a sense of urgency came over her she pushed herself harder, her legs trembling beneath her as she forced herself to go faster following the boy.

(Y/N) felt an unfamiliar tingle coursing through her body like thousands of needles pricking her skin gently the hair on her arms stood up as they saw the Kamado residence in the distance, the young girl stopped her eyes widened a familiar face laid down in the snow their arms hugging a smaller frailer figure (Y/N) fell to her knees her mouth slightly agape tears threatening to spill.

Tanjiro let out a wail of horror as he dropped the basket on his back tears threatening to fall, he rushed over to the lifeless form of his eldest sister who cradled their youngest brother his small body wrapped up in her frail arms protectively "Nezuko!" He cried out his trembling hands reached out ever so slightly "What happened? What's going on?" He choked out between sobs crying desperately.

(Y/N) watched the scene unfold frozen in the snow her heart dropped to the pit of her stomach as she clasped a hand over her mouth screaming like a banshee into the palm of her cold hand, tears running down her cheeks "What happened here!" her face draining of colour as her blood ran cold.

Tanjiro cried freezing as his burgundy eyes glanced inside the darkroom past the sliding door a gut-wrenching heartache washed over him as he saw the lifeless bodies of his family laying in pools of their own blood.

The boy stood up slowly swallowing the lump in his throat as he carefully crept into the room his body felt weak but he pushed his shaky legs to move "mom...." he said in a broken voice falling to his knees in disparity, (Y/N) perked up pulling herself up weakly her body trembling as she crawled on her hands and knees over to the grieving boy throwing her arms around him she pulled his tear-stained face into her chest shielding him from the horrific sight laid before him.

Her blood ran cold as she saw the remains of the Kamado family the young girl trembled breaking out into a cold sweat as she let out a shaky breath, "Mom...Hanako...Takeo...Shigeru... Nezuko...Rokuta..." Tanjiro muffled his cries into the girl's chest clutching her kimono desperately shaking in her arms.

(Y/N) perked up as she saw Nezukos fingers twitch ever so slightly the girl gently pushed the weeping boy off her (Slim/In-between/Plus size) form crawling over to the motionless girl, "W-what are you doing?" Tanjiro asked in a shaky voice wiping his runny nose as he watched her gently push Nezuko on to her back pressing her ear to her chest "She's alive." His burgundy eyes widened.

"There's a heartbeat..." (Y/N) paused her brows scrunched up a tingle ran up her spine as she felt something unfamiliar about the girl something different tanjiro looked at the girl in confusion as he ran over to his eldest sister, "What?" He asked in an alarmed voice grabbing the girl by her shoulder (y/n) looked up at him with a concerned expression "She's different." she paused for a moment "I don't know how I just know she is." She said her (e/c) orbs held a hint of uncertainty.

As she studied the unconscious girl carefully a look of scepticism masked her face "It doesn't matter, what matters is she's alive we have to get her help!" The Kamado boy said in a sense of panic, (Y/N) didn't argue instead she helped heave the frail girl's body on to the boys back the tingling in her body slowly became more intense light shingles turned into a painful stabbing sensation.

"If I can get her to a doctor she might still live!" The boy announced their tired legs carried them down the mountain, "We can take her to my uncle!" (Y/N) announced (e/c) eyes narrowed as she tried to make out the silhouette of the trees in the snowstorm.

Their lungs burned as they breathed in the icy cold air "how did this happen?" The boy cried out in despair tears threatened to fall, "Demons." (Y/N) grandmothers voice rang in her head she began to wonder if the Kamado family had been mauled by demons.

The thought sent cold shivers through her body Tanjiro stumbled almost tripping over his feet he steadied his feet letting out a sigh of relief, "Give her to me!" (Y/n) demanded to pull the girl off the boys back he watched in awe as the girl effortlessly pulled his sister into her arms without flinching.

"Let's go!" She said (Y/N) used her newfound strength to carry the girl in her arms a look of determination on her face teeth gritting together, "I won't let you die." The girl said under her breath as she pushed her legs to move faster (Y/N) froze as the frail girl let out animalistic noises.

Nezukos eyes seemed vacant as she stared up at her dearest friend (y/n) felt a tear slip from her eyes she felt the girl grab on to her (Slim/In-between/Plus size) form thrashing around with inhuman strength causing her to lose footing, "(Y/N)! Nezuko!" Tanjiro cried reaching out to grab them as they fell off a cliff (Y/N) reached out to him their fingertips brushed together as she fell screaming in horror.

The (h/c) haired girl landed on her back in the snow with a loud thud (y/n) gasped for air as the impact knocked the wind her out of her, she laid motionless in the snow stunned by the sudden fall her eyes staring into the cloudy sky with an empty look "Nezuko!" (Y/n) cried out loud as pulling her frail body up from the snow.

"(Y/N) you're okay!" The burgundy haired boy cried gratefully rushing to the girls' side he hugged her tightly a sense of gratitude he had lost enough he could not bare to lose the love of his life and his family all in the same day, he paused for a moment before pulling away slightly "Where's Nezuko!?" He asked suddenly the girls (E/C) orbs carefully surveyed their surroundings pausing as she noticed a figure adorned in a pink blood-soaked kimono standing in the distance between the trees.

"There!" She declared extending an arm pointing out the silhouette of a young woman hidden in the lifeless trees clouded by the snow they exchanged a quick glance before springing into action, "Nezuko, are you alright?" Tanjiro asked cautiously his voice laced with concern (Y/N) felt the familiar stabbing pain pricking at her cold skin.

"You don't have to walk!" The boy reassured reaching out to his sister desperation etched on his face (Y/N) extended an arm instinctively a feeling of dread washed over her, Tanjiro glanced sideways at his friend with a look of confusion Nezukos head hung low she was unresponsive she stood in the snow as a lifeless corpse drained of colour her kimono soaked in blood "Something is wrong, don't go near her."

She whispered cautiously instinctively pushing the boy behind her shielding him with her (Slim/Inbetween/Plus size) figure defensively as she backed away cautiously, (Y/N) froze as the eldest Kamado son pushed his way past her reaching out to his sister despite (y/n)  pleas to stay away "I'll carry you to town, okay!?" He said desperately.

"Nezuko," the boy gently placed his coarse hands on the girls shoulders (Y/N) eyes widened as the girl let out an animalistic cry launching herself at the boy her teeth bared like a hungry wild animal, The eldest Kamado boys burgundy eyes widened as he was thrown out of the way he watched in horror as his sister threw herself over his best friend attempting to tear her throat out.

(Y/n) used a branch to protect herself muzzling the girl (y/n) arms shook as she fought against Nezukos demonic strength it's just as grandmother described she thought to herself staring into the vacant pink eyes that once belonged to her dear friend, "Nezuko it's me! (Y/N) remember how I used to braid your hair when we were little! Like your mother taught me!" (Y/n) screamed trying to connect with any shred of humanity left in her dear friend.

"S-she just grew in size!" The young Kamado boy stuttered in a shaky voice as he came out of his frozen state his body trembling, "Nezuko look at me!" (Y/N) pleaded desperately tears streaming down her face suddenly the demonic girl froze loosening her grip.

(Y/N) flinched as she felt droplets of tears hit her face a sense of relief washed over her Nezukos vacant eyes suddenly had life in them she placed a tender hand over (y/n) tear-stained cheek, (y/n) leaned into her hand her lips curling into a warm smile.

The tender moment was short-lived when a mysterious figure emerged from the woods "Tanjiro get down!" The girl suddenly cried as she threw her body over the Kamado sister protectively shielding her from the cold blade.

The blade missed (Y/N) by mere inches she froze as she noticed locks of her (H/C) hair laying in the white snow "(Y/N)!" the eldest Kamado son called out desperately trying to reach out for her only to be thrown back by the stranger.

(Y/n) shielded the young Kamado sister from another blow they were thrown against a tree (y/n) cried out in agony she heard a snap as a rib snapped, She held the girl in a tight embrace a fierce expression.

A man stood in the distance he had long tied back black hair, he was adorned in an eerily familiar uniform covered by an oddly designed Haori, what really drew her attention was the blade he held in his grip.

"Why are you protecting it?" The mysterious swordsman asked coldly eyeing them girl suspiciously his sapphire blue eyes piercing her soul, "She's my younger sister, Nezuko!" Tanjiro cried desperately the stranger gave a look of dismay a hint of disgust in his eyes.

"You call that thing your sister?" He replied coldly (Y/N) held the petite girl protectively in her arms ignoring the pain from her cracked rib, she swallowed the lump in her throat beads of sweat covered her (s/t) skin her body trembled from the pain she had to save Nezuko.

Her (e/c) widened as the man disappeared reappearing in front of her (y/n) threw her body over the girl shielding her from his deadly precision with his blade.

(Y/N) eyes widened as she hugged cold air paused momentarily staring at the empty space between her arms her (e/c) orbs locked on to a pair of cold Safire eyes in the distance, "Nezuko!" They cried desperately as she thrashed around in his strong grip he stared back at the two with a stoic expression "Don't move," he said coldly making them freeze.

The cold winter air washed over them creating a fog-like atmosphere (Y/N) angrily dug her nails into the palm of her hands as he held Nezuko like some wild animal sent to the slaughter, "my job is to slay demons." He said his lips pressed into an unflinching deep frown his brows narrowed together an air of authority lingered around him.

Countless thoughts ran through her mind as she processed the situation the world of fantasy was anything but a fantasy, "Needless to say, I'm going to decapitate your sister." He said in an apathetic tone a stoic expression on his pale face, (y/n) felt her body rub cold as he raised his sword "Hold on!" Tanjiro pleaded desperately holding back tears "Nezuko hasn't killed anyone!" He screamed in a broken voice.

"Back at my house, there was another scent I'd never smelled before!" He said trying to reason with the mysterious stranger, "That's probably the one who killed my family! It wasn't Nezuko." (Y/N) watched the scene her (e/c) orbs widened the thought of another demon capable of slaughtering a whole family mercilessly made her spine shiver.

The demon slayer turned his cold gaze towards (y/n) a look of uncertainty on his face "Are you human?" He asked plainly pointing the tip of his sword at the girl who was hunched over in the snow, he sensed something demonic about the (e/c) eyed girl.

"What!? Of course, she's human!" Tanjiro replied the stranger turned to the boy cocking an eyebrow opening his mouth to reply "Of course I am what kind of question is that!" She retorted tears of desperation falling down her cheeks as her head hung low letting her tears spill into the snow "do I look like a demon!" She asked between sobs.

The raven-haired man had a suspicious look on his face his Sapphire eyes studied the frail-looking girl "what's your name?" (Y/n) brows furrowed in confusion as she stared at the man with puffy red eyes, "(Y/N) (L/N)." she replied hesitantly his cold eyes widened subtly as he lowered his sword slowly "I see." He replied plainly "You wouldn't happen to be the daughter of the deceased Lady (l/n)?".

"How did you know my mother!?" (Y/n) asked in a shaky voice perking up the demon slayer frowned he didn't respond instead he turned his sword on the thrashing demon in his grip, "Please give my sister back! I won't let her hurt anyone, I'm going to turn Nezuko back into a human." The boy pleaded, "I swear I'll heal her!"

(Y/N) watched the boy with a sense of admiration as he gave his most sincere please "she can't be healed." The demon slayer protested coldly a look of apathy carved into his face.

"Once you become a demon you can never go back to being a human." He explained cooly as he steadied his sword raising it to strike down the demon he held in his clutches, "I'll find a way! No matter what so please!" He declared balling his fist pulling it to his chest "so please don't kill her! I'll hunt down the one who slaughtered my family!" He pleaded through broken sobs of desperation.

"I'll make everything right." (Y/n) felt useless as she watched her friend plea for his little sister's life without a shred of hesitation, "Please, don't do it!" Tanjiro choked out between sobs of desperation tears falling down his face her eyes widened as the boy got on his hands and knees in the snow begging.

"I'm begging you not to! Please! Don't kill my little sister!" (y/n) pulled herself up onto her trembling legs making her way to the burgundy haired boys side bowing sincerely "Please spare his sister he has lost enough the Kamado family have always been good people if you spare her,"

(y/n) paused thinking over her next words carefully "I'll take responsibility for her actions if she kills another human I'll put her down myself!" (y/n) said ignoring the burning sensation in her hands as they pressed against the cold snow.

The raven-haired stranger paused hesitating for a moment his Safire eyes staring into her (e/c) orbs "Do you swear on the (L/N) family name that you'll take responsibility!?" He asked hesitantly lowering his sharp sword, Tanjiro watched the exchange his burgundy eyes studied the demon slayers face closely.

(y/n) pondered the mysterious stranger's words carefully a look of determination spreading across her face "I do!" She replied confidently, Giyuu paused contemplating the situation a cloud of snow washed over the forest.

When the snow cleared the mysterious stranger disappeared without a trace (y/n) noticed the eldest Kamado son lying unconscious but unharmed in the snow, "You have given me your word young (L/n) don't make me regret it!" a familiar cold voice whispered in her ear from behind (y/n) glanced over her shoulder her (e/c) hues met a pair of cold Safire blue ones.

She opened her mouth to respond when she felt a sudden sharp pain in the back of her skull her last thought was of the burgundy haired boy as the world faded into darkness.

(Y/n) flinched as she felt snowflakes kiss the soft (s/t) skin of her face her (e/c) orbs fluttered open a familiar pair of burgundy eyes stared down at her, "tanjiro?" She said weakly the eldest Kamado son ran his fingers through her (curly/wavy/straight/natural/braided) hair "You're finally awake, I didn't want to leave without saying goodbye."

(Y/n) her eyes started to water as tears threatened to fall she stared up at him with a heartbroken expression, "G-Goodbye!? I'm not letting you leave without me." She protested clutching his shirt Tanjiro cupped her face in his coarse hands.

"I can't take you with me." He replied swallowing a lump in his throat as he fought back tears "it will be dangerous I can't lose you too." Said pulling her into his chest, (y/n) sobbed into his firm chest clutching his shirt weeping remorsefully.

Tanjiro had a pained look on his face as he hugged her close to his body tears threatened to fall from his burgundy eyes "I won't let you leave me!" (Y/n) replied clutching on to him tighter, "I have to!" He replied a little more sternly giving her shoulder a reassuring squeeze as he pulled away.

"Why!?" She choked out in broken sobs clutching on to the frail burgundy haired boy "Because I love you!" He said weakly gently removing her hand a pained smile on his face.

"I have loved you since the day I laid eyes on you when I saw you it was like seeing colour for the first time suddenly the world was a beautiful place." He said in a soft voice (y/n) paused as they locked eyes, "You have always been the most beautiful thing in my world if I lost you I'd lose everything that makes the world a place worth living in."

(Y/n) was frozen in place it was the confession she always dreamed of hearing "This is goodbye (y/n) I won't ask you to wait for me." He said in a broken voice, wiping his tears with the sleeve of his Haori "I'll come to find you." (Y/n) replied glancing at Nezuko giving her a warm smile.

"Both of you." (Y/n) froze as the young Kamado sister wrapped her arms around her (Slim/in-between/plus size) figure (y/n) bit back a pained scream, ignoring the pain from her ribs she wrapped her arms around Nezuko pulling her close "protect your brother for me until I can find you both." She whispered into her ear.

"I have something for you." (Y/n) said as she removed her old necklace sliding it around the girl's neck clipping it in place Nezuko admired it, "You always admired it you said it was the most beautiful thing you've ever seen." She paused swallowing a lump in her throat holding back tears "now it's yours, you were like the little sister I never had." Tanjiro watched the exchange through pained eyes.

(Y/n) paused as she felt the petite girls frail hand slide into her soft ones Nezuko tugged her arm dragging her over to Tanjiro, "No Nezuko she can't come it's dangerous." The eldest Kamado son protested pulling their hands apart Nezuko let out noises of protest grabbing her sleeve Tanjiro couldn't hold the tears back anymore "don't make this harder than it has to be I don't want to leave her either."

(Y/n) reached out to the girl hugging her tightly "it's okay go I said I'll come to find you I won't let you down." She paused as she felt teardrops hit her shoulder, (y/n) pulled away wiping her tears with a pained smile watching them leave her fists clenched she didn't know how but she knew she was going to find a way to become stronger and save Nezuko.

Note: For those of you who noticed that I skipped over some dialogue and information I promise that will make sense in upcoming chapters.

If you're wondering yes (you) do become a demon slayer again the parting of characters will be short term and will make sense in upcoming chapters.

I'll also be revealing the results of our poll deciding who will be your side and companion, again I'm open to constructive criticism and requests.

Kind regards,
