A/n— So, this is 18+ and I guess it's got a bit of past trauma in it. I mean...Tomioka-San is in it you guys. Anything in 'these things' are Y/n's thoughts!

One day while walking through the woods I saw a tall, dark haired male fighting what looked like a woman with fangs and long, green hair. I didn't know what to think of it at first so I just watched until the woman looked at me. I froze and pulled out a kunai since I didn't have my sword on me and gripped it tightly as she looked at me.
"Hello little one~" she said quietly, her voice very alluring. I stared, my expression fighting between disgusted and worried. All of a sudden her head fell from her shoulders and my eyes widened slightly though I had seen this happen time and time again.
"Are you alright?" A quiet voice asked me. I looked over to see the male looking at me. Quickly, I nodded and hid my kunai underneath the hoari I was wearing.
"Y-yes I'm fine...was-was that what I thought it was?" I asked him quietly my voice a little shaky.
"A demon. Yes." I looked at the ground as I processed his words. It immediately reminded me of my older brother but I didn't speak until the male turned to leave.
"W-wait!" I said quickly, "what's your name?..." he faced me for a moment and sighed.
"Giyuu Tomioka." He said plainly. The entire time we had spoken his expression hadn't wavered in the slightest. I nodded in acknowledgment before he turned again and left. I watched him leave before heading home myself. After a long, boring walk I made it back to my large but usually empty home. After my brother's death several years ago I had been alone. I pushed the door open to see several people sitting on the couch.
"Back to work..." I mumbled before moving each of them into a room and getting them food and drinks. I checked them each for any wounds they might have. None of them had anything major just a few cuts, bruises, and scrapes. Once I was done I heard a knock on the door and quickly ran to open it just to see several Hashira in my doorway. 'What did I do now?'
"Hello Ms. Y/n, do you happen to have a few open rooms for the night?" I smiled softly and ushered them in before quickly speaking.
"Yes, yes. I have 3 open rooms upstairs, if that's alright?"
"Oh, yes. That's perfect!" He said loudly, giving me a cheerful smile.
"So you take care of slayers?" A young woman asked me quickly.
"Ah, yes. I've done it for a while. Uhm- may I ask for all of your names?" The girl smiled at me and chuckled.
"I'm Mitsuri Kanroji, the Love Hashira!" She said cheerfully, "that's Shinobu Kochou. She's the Insect Hashira!" She pointed at a girl with brown and purple hair.
"I'm Tengen Uzui and this is my flashy best friend Kyojuro Rengoku!!" A tall white haired man said to me, "I'm the Sound Hashira and he's the Flame Hashira!" Another man with white hair and lots of scars then spoke.
"I'm Sanemi Shiniguzawa, the Wind Hashira." I nodded and looked at the other 4 who hadn't spoken yet.
"What are we-" he then stopped for a moment, "oh wait...I'm Muichiro Tokito, the Mist Hashira." He looked a bit young, maybe even younger than me...
"I'm...Obanai Iguro...the Serpent Hashira." A shorter man said to me. He seemed as though he didn't want to speak at all.
"Hello my child. I am Gyomei Himejima, the Stone Hashira." He said loudly but his voice was kind and he seemed to be praying while doing so.
"I'm Giyuu Tomioka the Water Hashira." His tone was the same as 'oh wait...that's the guy I met earlier...' I smiled at everyone and nodded.
"Well it's nice to meet you all. I'm Keiko, though I'm not a Hashira I am a slayer. My ranking is Tsuchinoto." I said calmly as I folded my hands together behind my back. I mentally counted how many of them there were. 'Crap! I'm down a bed with those other slayers here!...I'll have to figure it out like I usually do.'
"Oh, you're a slayer? Then why do you house all of the other slayers?" Shinobu asked me kindly. She was smiling but I could tell it was a fake one. I decided not to mention it though.
"This was originally me and my brothers home so I'm not used to the quiet and I hate being alone." I said calmly my voice quiet, "he died a few years back during his final selection. He was trying to protect his friend." The Hashira all stared at me, some concerned and others just sad. I mostly ignored it until til I recognized half of the hoari Tomioka was wearing. It looked like my brothers... 'he must be the boy Irokodaki had told me about. The one my older brother, Sabito, saved...that he gave his life for. The reason...no. I can't blame him...'
"Ara, ara. Why are you staring at Tomioka?" Shinobu asked me. I jumped slightly at the sound of her voice before shaking my head and looking at Tomioka again.
"That," I said pointing to his hoari, "did you get it from someone?"
"Yes."
"Who?" He just stared at me.
"Tomioka-San, answer her~." Shinobu interjected.
"A friend." He said quietly. I soon noticed that most of the Hashira were leaving the room and heading to the bedrooms upstairs until it was just me, Tomioka, and Shinobu in the room.
"You don't have any-" I glared at her. I may not be much in size but when I gave you MY glare is was terrifying.
"Was his name Sabito?" I asked softly. I wasn't sure if he would answer me so I looked for even a hint of something, anything, in his expression. Sadly, I didn't catch anything...
"Ara, Ara...Tomioka-San having a friend? Impossible." She laughed and I looked at her.
"You don't either." I deadpanned.
"Yes I do!"
"Who?"
"Kanoa-" I cut her off quickly.
"She's your 'adopted' sister, and she doesn't even talk to you." She froze and stared at me.
"I-" I cut her off again.
"Shinobu, you're the one with no friends." She quickly walked off and went upstairs muttering angrily.
"You didn't have to do that..." Tomioka mumbled quietly. I just shrugged and smiled at him.
"I don't mind-"
"Yes..." he said out of nowhere, confusing me at first. Then I realized that he was talking about my earlier question.
"Did he tell you...about a sister?" I whispered.
"Once. Just before we left for Final Selection." I nodded slightly as he continued quietly, "he asked me to keep an eye on her, but I didn't know where to find her...and he couldn't tell me." I sighed before chuckling quietly.
"Well you've officially met her." I said softly. "I'm Sabito's younger sister." He stared at me for a moment.
"You're Sabito's- I'm so sorry...I should've tried to save him..." he mumbled. His voice was slightly shaky and I could see his hands shaking as well.
"No! It's quite alright. You don't need to be sorry! It isn't your fault." I said quickly before taking his hands in mine, which were small in comparison, "my brother protected you for a reason. It's not your fault he died, Giyuu." I could see the tears building in his eyes as I spoke. I sighed and hugged him using my right hand to softly rub his back as I tried to call him down. He wrapped his arms around me and sobbed into my shoulder, his body was shaking, and I could tell he really cared about my brother. We stood like that for a few minutes until he stopped crying and let go of me taking a small step back.
"Thank you..." he whispered, "is there anywhere I can sleep? I heard them upstairs saying there's no more beds..." I chuckled a bit embarrassed as I thought before answering.
"Oh, yeah..." I mumbled, "you can have my room, if you'd like."
"Then where would you sleep?" His tone was now back to the bland, empty tone he had before.
"Oh, uhm- I'm not sure, but I don't usually sleep so it isn't a big deal." I said quietly.
"Are you sure?..." he said softly a little concerned, at least I assumed so by his expression.
"Yes, of course!" I said brightly, giving him a soft smile. He then nodded, his expression was still the same as before. "Well, here I'll show you where my room is." I said quietly before leading him up the stairs, towards a door at the end of the hallway. I opened it and smiled at him.
"Thank you, Y/n." He muttered before walking in behind me.
"Of course! I'll go so you can get some sleep." I said softly. I turned to leave but he grabbed my wrist and pulled me close to him.
"Don't leave..." he said quietly, pulling me into his arms, "lay with me." He held me in his arms and pulled me to the bed.
"I- uh- ok..." I mumbled as I curled up in the bed beside him. He leaned over, lying slightly above me. I blushed a soft shade of pink as he leaned close to my face, planting a soft kiss on my lips. I kissed him back, wrapping my arms around his neck and pulling myself closer to him. We continued to kiss, his tongue slipping between my lips and into my mouth swirling around my tongue as we kissed. He eventually pulled away breathing roughly. His hands then slipped under my shirt and slid it over my head. He then pulled his own shirt and pants off before slipping my skirt off of me. He then grabbed my waist and slowly slipped my panties off of me and tossing them to the side. He slipped his own boxers off and leaned over me again. Grabbing my thighs and lifting my legs over his shoulders. He soon slipped his length into me as he held my thighs and I shuddered slightly. He slowly started moving his hips back and forth against mine. My hands subconsciously reached out and interlocked themselves in his hair yanking on his slightly. A weird feeling built in my throat and I moaned quietly. I heard a small grunt slip from Tomioka as I yanked his hair again. He started to push himself into me much harder as his pace quickened and slowly started to get sloppy. I soon felt a know build in my stomach and I moaned loudly.
"I-I'm gonna cum!" I whimper-yelled at him. He grunted quietly and shoved his length as far into me as he could manage, his waist slamming into my hips. I cried out, yanking his hair as the knot in my stomach popped and I came on him. At the same time he came inside me, his thick, warm cum filling up my insides. He then slowly pulled out and rolled over, laying beside me.
"Wow..." he muttered before we both yawned and fell asleep.
