I sit up and look around and I'm in a very small house in an old violet kimono that I've never seen before. My hair is pinned up with a ceramic clip and I feel.. Smaller.. Skinnier.. Weaker.
"(Y/n), honey. Your father is waiting for you outside!" A woman walks into the room and I hardly recognize her. She has long black hair thats kept in a side braid, and tired blue eyes. Her hands are well calloused and not delicate in the slightest. But she's beautiful. Her face briefly rings through my mind with vague nostalgia.
".. What?" I asked softly, still staring at her blankly, trying to connect the dots.
"Listen to your mother, dear." The woman teased lightly. "You're acting so strange today!"
"Oh um.. Yeah.. Sorry I'm just feeling out of it today.. Sorry mother." I said automatically before walking outside.
Its a warm summer day. Bright blue sky, lazy white clouds. A pond full of lily pads and a man standing below a large apple tree in familiar black clothing.
Familiar.. Ha.. This entire scene is frighteningly familiar. Like something I could've lived through but never had a chance to. Fate is cruel.
I walked over to him and immediately recoiled as i saw his face. "It's.. It's you.." I said in shock, reaching for my swords that aren't there.
"Your father? Yes? What about it, (y/n)?" He said with an easy smile. A smile full of sharp teeth.
A demon.. This demon.. Standing in front of me is my father. A mortal mother.. A demon father. No... Not a demon. The demon. The man before me is Muzan Kibutsuji.
"What the fuck.." I whisper and I take a step away from him.
Muzan just smiles at me, "not what you expected?"
"Fuck no!" I shout out loudly, finding myself back in my uniform, swords on my sides. "This is a dream!"
"Is it?" Muzan said with narrowed eyes.
I have to think of a way out of this.. That's when it hits me. The quickest way to wake up from a dream.. Is by dying in the dream. "Don't you want to know what this place is?" When I silently freeze in place, he breaks into a grin. "This was our home from when you were a baby. Your mother, that woman there, found out I was a demon.. She tried to take you and run. I could've easily let her go, believe me I would've. But my pride wouldn't allow it."
".. So you killed her." I said through gritted teeth.
Muzan nodded, "yes. I tore her apart with my bare hands. Limb from limb. Slowly. She.. Was delicious." He said it as if he could still thrive on memories of the taste alone. "I was going to devour you as well.. But a young woman with snowy hair grabbed you and fled to a house surrounded by wisteria where I couldn't enter." He reached towards me and caressed my cheek, "but you're destined to be as much of a monster as I am, (y/n).. Its in your blood! So tell me.. Do you still think all this is a dream?"
I step away from him and reach towards my hips, where my swords have become very tangible and real once more. That old kimono, became my uniform and the smell of wisteria and gunpowder pulled me back towards my senses and turned my nerves to steel. "Yes. It's a dream. I'm sure of it.. And you.. I'll destroy you with my bare hands. I'll end you the same way you ended her. And I'll enjoy every second of your down fall, you twisted bag of shit." I hissed through a forced grin as I grabbed my swords and removed my own head.

My eyes fly open and I find myself face to face with a scared looking girl.
"Aah!" She yelps, dropping a knife. She instantly runs back down the train cart, slipping a rope from my arm and dragging it behind her.
I turned to see Tanjirou's unconscious body burst into flames while Nezuko, who watched with wide eyes, was crying. Rengoku has his hand closed around the throat of a girl, but he was still sleeping. "What the fuck us going on around here?!" I curse softly as I slide Inosuke off of me, running my hand through his hair before placing his mask back on him.
All of a sudden, Tanjirou is wide awake as well. He looks around for a moment before his eyes land on me. "The ropes!"
As he moved to cut them I shook my head. "No! They aren't real ropes! If you cut them, everyone stays asleep forever!"
Tanjirou slowly nods, "Nezuko! Burn the ropes!"
She does as he asked and instantly one of the girls tries to attack him with what appears to be an icepick. As he deflects, I realize that there are several other people getting ready to attack as well. But behind them, someone was weeping.
I leap into action and swiftly knock all of them out, except for the boy in tears in the back. He looked weak and sickly like he could keel over any day now. And somehow it reminded me of Kagaya. "You.. Are you alright?"
He sniffed and tears welted up in his eyes. "Be careful out there."
Tanjirou nodded and took Nezuko with him down to another cart.
I smiled at the boy for a moment, "I'm sorry you're sick. I understand all too well."
His eyes widen and a tear rolls down his cheek, "I just wanted to stop suffering.."
I pat his cheek with a gentle hand, "..I know. Please go somewhere safe okay?"
He nodded and held his hand over mine for a moment before running off.
"Rengoku!" I shouted patting his cheek. "Time to wake up you lazy bastard!"
Nezuko wandered back inside and looked at me for instructions.
"Wake him up! I'll get the other two!" I said nervously. "We have to hurry, I think Tanjirou's in trouble!" I moved over and shook Inosuke gently before removing his mask once more and slapping him sharply across the face.
"Ow hey!" He shouted before grabbing onto my arms harshly. His eyes widen before he lets me go. "(Y/n)..? Are you the bitch that hit me?!"
"Yeah, sure, whatever!" I said frantically. "Fight me about it later!"
"Wait.. What's going on?" He said as he grabbed the boar head.
I shrugged, blinking back tears as best as I could manage. "D..don't worry about it right now.. I'll tell you later. For now, there's a demon that's fighting Tanjirou! He's very strong and needs help!"
He nods once before whispering to me, "Don't die okay? I'd be pretty pissed off if my rival was killed." Inosuke ruffles my hair and then places his mask back over his head before running back down the hall.
"Nezuko, I trust you'll handle things here? I'm going to check in on the other people on the train!" I shouted.
She nodded and waved me off. That was all the reassurance I needed.
I ran off down another hall, and I nearly threw up seeing the condition of the cart. The walls appear to be slowly consuming the people on board. I instantly shift into a stance. "Breath of the Moon, twelfth form.. Crescent vines.." I whispered to myself as I dove around freeing as many people from the train as possible.
I look up to see Rengoku standing in the doorway with his arms crossed, "wow good work! But I'll take it from here!"
"But there are 5 carts back here.." I mumbled before shaking my head. He can manage his own, so its best not to argue and waste our time. "..okay. You got this! I'm going after the neck then!"
He ruffled my hair, "Tanjirou and the boar boy are headed that way now! Once you get there, back them up as much as possible. But if you see an opening, take charge!"
"Alright!" I said boldly, stomping my foot onto the ground sharply. As I close my eyes, I can feel the entire layout around me. Thats when i notice the strongest point is on the engine of the train up front. "I found it! Good luck, Aniki!"
"You too, Mouse!" He said with a bright smile.
Both of us took off to our respective jobs. He started handling things as he said he would, and I jumped through a hole in the roof, landing on top of the train. I start running forward as quick as possible until I see Inosuke a cart or so ahead of me.
"Inosuke!" I shout above the wind.
He turns and waves at me dismissively, "get back inside!"
"Fuck you!" I hissed as I reached him, "the demons neck is in the very front of the train!"
"Where all the coal is piled up?" Tanjirou asked from inside.
"Yeah!" Inosuke and I shouted back.
"Let's go then!" Tanjirou called out.
