𝑫𝑹𝑬𝑨𝑴𝑺

As Kyojuro ate he kept repeating "tasty!" Every time he took a bite "uh rengoku" you heard a voice say you turned to see tanjiro and his friends "tasty!" Kyojuro yelled "yeah we heard you the first 50 times" tanjiro said "oh hello tanjiro" you said with a smile he smiled back and said hello "oh it's you, you were at the mansion" Kyojuro said "yes I'm Tanjiro Kamado this is zenitsu and inosuke" tanjiro said as the boar headed kid puffed out "I see also is there one in that box" Kyojuro said "right my sister Nezuko" tanjiro said looking at the box "yes I remember that demon since the master accepted her I will keep my peace" Kyojuro said before patting the seat in between the two of you "sit down won't you" Kyojuro said as you smiled.

"And what brings the three of you here a mission?" Kyojuro asked  "yes we were ordered to join you and miss y/n we received a message from a crow which led us know the casualties were on the rise" Tanjiro said "ah that's why your here understood!" Kyojuro said "sir there was one more thing something I wanted to ask you" tanjiro said "oh what is it?" Kyojuro asked "it's about my father" tanjiro said "what about your father?" Kyojuro asked "he was a frail man" tanjiro said "was he now" Kyojuro said "and he could preform a kagura dance in freezing weather" tanjiro said "well good for him" Kyojuro said "and then!" Tanjiro said as Kyojuro repeated it "hinokami kagura, the dance I found myself doing it just like my father used too I was hoping if you knew anything about that If you'd be willing to tell me.." tanjiro said when your eyes went wide you remember your father telling you something about a breathing style like flame breathing but not at the same time "certainly but I don't" Kyojuro said "sun breathing.." you whisper as you cover your mouth you were still an infant when you heard about it it was something kokushibo brought up. Kyojuro and tanjiro looked at you in confusion "sun breathing?" Tanjiro asked "it's the first breathing technique used by a man my father dare not utter his name so I don't know what it is but I vaguely remember my uncle and dad talking about it I was maybe 2-3" you said before going quiet again when Kyojuro said "YOU SHOULD BE MY TSUGUKO!"  Making you and tanjiro shocked.

"May I see your tickets please" one of the conductors said in a slow voice you Kyojuro Tanjiro zanitsu inosuke handed the guy your tickets "thank you very much" he said looking down "apologies for the sword but there is a reason" Kyojuro said and soon enough a demon appeared "what a giant did you use a blood demon art it was difficult to detect you know this if you bare your fangs at the innocent I will see your bone turn to ash! With my bright red blade of fire" Kyojuro said he truly was the sun he shone like a bright sun "flame breathing first form unknowing fire" Kyojuro said killing the demon and in an instant another demon was in my line of fire "Third Form: Loathsome Moon, Chains!" You yelled you perform two extremely broad crescent-shaped slashes with your double sided scythe directly in front of you, from which a storm of smaller crescent moon blades are released.it was graceful and beautiful you killed the demon as your mask began to fall from the action you swiftly put it back on. When you turned to Kyojuro you saw the three boys practically floating around him asking him to tutor under him you couldn't help but laugh Kyojuro was so kind generous and he had this soft spot for everything delicate and fragile. The three boys kept calling him bro and brother it was cute "thanks so much big bro they said with big smiles on their faces before we knew it we were passed out.

Blood demon art dream state:

Blood everywhere on the floor this place familiar to me it was the infinity castle as I looked around I saw my mothers dead body my fathers dead body and all my uncles dead slaughtered but not turning to ash I began screaming not even crying just screaming when I heard a voice "this is what happens when you break the rules did you really have to lie I trusted you and loved you" Kyojuro said his haori covered in blood "what have you done what have you done" I screamed I never wanted them to die I never- your thoughts were cut off by your mother's voice "you said you were going to protect us y/n you said you wouldn't let them kill us!" Daki said "you must be the monster to let them all die" you heard Kyojuro say but all you could do was run the sound of nakimes biwa rang and it felt like you could not run away "you should have never been born" you heard a voice say I began to wake something shifted within me I was surrounded by Nezukos flames and I know what I had to do with one swift motion of my scythe I killed myself making this awful nightmare end.

Asuka pov
As I entered this girls dream I saw dead bodies everywhere and there she was just screaming "I need to find her spiritual core and destroy it" I whispered and soon I found it I cut open and her soul was dark it looked purple and black and soon I found her spiritual core it was light purple but before I could destroy it I felt a chill up my spine then she awoke and my there were no more dreams.

Y/n awoke with a gasp, beads of sweat clinging to her forehead. The remnants of the nightmare lingered, haunting her thoughts. As she looked around, the reality of the train car and the rhythmic motion reassured her. Kyojuro, Tanjiro, Zenitsu, and Inosuke were still there, oblivious to the torment she had endured.

Y/n's POV:

Breathing heavily, I steadied myself, realizing the weight of the dream. The echoes of my past, the guilt and fear, clawed at my consciousness. Glancing at Kyojuro, who was engaged in conversation with the trio, I hesitated to share the haunting images.

The journey continued, each sway of the train a reminder of the battles ahead. As the rhythmic clattering persisted, I sought solace in the presence of my comrades. The dream, a vivid manifestation of my inner turmoil, lingered like a shadow.

Kyojuro turned to me, concern etching his features. "Y/n, is something bothering you?"

The nightmare lingered on the tip of my tongue, but I couldn't bring myself to burden him with the haunting details. "It's nothing," I replied with a forced smile.

As the train surged forward, the mission loomed closer. The mysterious dreams, my concealed past, and the uncertainty of the battles ahead weighed heavily on my mind. Yet, with Kyojuro by my side, I found strength to face the demons, both within and without.
