‘Knock, Knock’

Your head darted toward the door, and you suddenly became confused. You had been reading a book while lying back on the couch. You stood up and made your way toward the door, then peeked through the peephole to see if anyone was standing there. It was just your porch light shining on the stone pathway leading to your front door. Besides that, your fenced gate was still closed. You opened the door slowly, and there was a gift sitting on the floor.

'Hello, is anyone there?' you called out, glancing around the area in front of your house. The only response was the sound of crickets filling the cool night air. You picked up the gift and turned back into your house.

'Maybe it was just one of the Demon Slayer Corps members dropping off a gift,' you thought as you placed it on the coffee table in your living room. This had to be the second time this had happened; the first was on your 19th birthday, and now it was your 20th. You looked at the clock—it read 12:03 AM. It was strange because the gift had been dropped off right at midnight. Who would drop off a gift that late?

You opened the gift slowly. Inside was a little hair clip that sparkled under the living room light. Your eyes twinkled with excitement—someone knew you had been eyeing this object but hadn’t yet obtained it at the night market. The only people who had been with you that night were Tanjiro and Rengoku after celebrating the victory of the Mugen Train mission. Of course, that was after everyone had recovered.

There was just one thing that would constantly pop up in your mind while sleeping: a recurring nightmare. It was always about the night of the Mugen Train mission. After Lower Rank One was defeated, an Upper Moon appeared shortly thereafter. Out of Zenitsu, Tanjiro, and Inosuke, you were the most capable of fighting that battle alongside Rengoku. The fight was difficult at first, but the demon struggled to read your moves, making it easier to target Rengoku. The Upper Rank demon attempted to punch Rengoku, but you jumped in the way, getting your side injured from the impact of the demon’s attack. You stared the demon straight in the eyes, and he stared back at you in shock.

You sat there admiring the gift, but you definitely couldn’t wait to thank Rengoku or Tanjiro for it.

The sun had risen and hit your face, causing you to jolt awake. 'Y/N, Y/N, you were requested by Lady Shinobu to stop by the Butterfly Mansion for a check-up!' Your crow, Shiro, had landed at your window. 'Okay, I got it,' you grumbled tiredly, then rolled out of bed to get ready for the day. 'On my birthday, Shinobu decides to schedule a check-up,' you sighed, brushing your teeth before heading out to the mansion.

You approached the walkway and walked through the doors. There was silence; usually, the Butterfly triplets would immediately greet you at the door. Growing curious, you continued down the corridor. You reached the end of the hallway and pushed through the double doors, only to be met with loud screeching sounds and confetti being thrown in your face.

'HAPPY BIRTHDAY, Y/N!' a big group of people yelled out, and you smiled widely at the surprise. The Kamaboko Squad ran over to you for a hug, squeezing you tightly. 'Wow, you guys are amazing!' you laughed, wheezing for air at the same time. 'You deserve this for all your hard work,' Rengoku clarified, smiling down at you. He knew you had spent your previous birthday recovering the entire time.

'Oh, by the way, thank you for dropping off a gift at my doorstep last night!' you thanked Rengoku, and his eyebrow rose. 'I didn’t stop by last night,' he replied, growing concerned. You both looked at Tanjiro, and he shook his head. 'No, I didn’t visit last night either,' Tanjiro answered. 'But you guys were the only ones with me at the night market when we celebrated,' you said, growing confused by the situation. 'Hmmm, it seems you have an admirer!' Rengoku exclaimed, rubbing your head teasingly.

The night ended with celebrating your day with the people you enjoy and love the most. You got ready for bed and went to the kitchen for a midnight snack to get comfortable before sleep.

‘Knock, Knock’

You glanced at the clock; it was midnight. Growing curious, you quickly walked to the door and it swung open. Time seemed to stop, and your body froze at the sight before you.

“Long time, no see,” the person spoke, breaking the silence. Your jaw dropped. You turned quickly to reach for your sword, but before you could, you were pinned against the living room wall.

“How do you know where I live?” You gritted your teeth. “That’s no way to greet someone who gifted you something,” he said, staring into your eyes with a smirk. “You think those dimwits would have known you liked the little hair clip?” He placed a finger under your chin, lifting your head to look into his eyes. “You’re the demon who almost killed me that night!” You hissed at him. He tilted his head, “try again. I didn’t try to kill you— I tried to kill him,” the demon said with disgust. “But after that fight, I grew interested in you.” The man smirked, “I’ve never fought someone whose movements I had such difficulty reading, which made it easier to target Rengoku.”

“I’ve been watching all your moves, and I couldn’t keep my eyes off you,” he continued, his voice filled with anticipation. “But now, I can finally devour you right here.” The demon licked his lips and immediately crashed his lips onto yours. Something inside you just complied with what he was doing. You didn’t know if you were under a spell, but it excited you.

He continued, even leading you to your bedroom. “This is going a different way than I thought it would,” he chuckled, starting to kiss down your neck. “Like what? Trying to kill you?” You moaned, and he raised his eyebrows, glancing up at you to see your reaction. The demon knew you were enjoying, not having anyone touch you like this in a long time. Maybe you had fantasies about Rengoku, but it never went that far.

The demon kissed down your stomach and lifted your black nightdress. Your pink lace panties covered your are, amusing the demon even more. He licked and kissed, teasing you, making you squirm under his grip. “D-don’t do that,” you whined, and he grinned at your whining. “I never knew I could get one of the Hashira in this state.” He pulled your panties to the side and began attacking your clit. This drove you crazy because nothing like this had ever happened to you. You did have action a few times here and there, but you were never on the receiving end.

“Hmmm, I can tell this is your first time,” he moaned, enjoying your movements, knowing you were liking the moment. Your face grew red at his words. “N-no,” you stuttered, and he looked up at you, gazing into your hooded eyes and open mouth. “No?” He pulled away, and you reached for his head to pull him back. “I-I— please don’t stop,” you begged, and he obeyed your orders. “That’s what I thought,” he smirked and continued.

The demon began to lick and suck faster, the more you moaned out loud. You clenched your eyes shut, coming closer to your high. He knew you were close and pulled away quickly. You gasped at the cold air hitting where his head had been. “You don’t get to finish yet,” he whispered in your ear. Then he flipped you over on your stomach, pulling your bottom up, your back arching, and your face in the pillows. Your area was dripping from his saliva and your fluids. “I like this view a lot.” He threw his pants off and lined up at your entrance, entering in quickly without letting you adjust. You yelped at the new feeling as he definitely stretched you out. “You like that, don’t you?” He hissed in pleasure and continued to pound into you. You gripped the bedsheets, exciting him even more. He wrapped his arm around your waist, reaching for your dripping clit, rubbing it to get you more aroused.

This sensation made your body go numb due to not experiencing this before. “I’m almost there!” You groaned, though your voice was muffled. Your eyes rolled back as his moans and your skins clapping together had filled the air. “God, you feel so good,” he bit his lower lip, letting it all out onto your body. Your body went limp, and he smirked at your state. “I guess this is where you kill me now?” You spoke into the linen on your bed, and he chuckled. “No, this is just the first time.” He traced your body with his fingers, “But this won’t be the end,” the demon said as he stood up to depart.

“Wait,” you sat up as he made his way toward your open window. He glanced over his shoulder, looking back at you. “What’s your name?” You asked.

“It’s Akaza,” he answered.

Just as your bedroom door opened wide, both of your heads darted to the door, where Rengoku stood in disbelief. Akaza ran off, and Rengoku quickly turned to you, rushing to your aid to see if you were injured.

It was just too hard to stay awake longer. Your vision was blurry, and you couldn't make out what was in front of you. Your face was wet from yours and Kyojuro's tears mixing together. It pained you to see him the way he was when you were being taken by the kakushi, "she's closing her eyes, how long do we have!" All you heard was the screams and cries of the three teenagers and Kyojuro's as you went away.

Your eyes opened at the bright morning sky and your surroundings were different, "where am I?" You stood up from your spot and made your way to a gate that was standing in front of you, "this is the butterfly mansion." You opened the door and saw Tanjiro and the teenagers looking devastated, "hey, why are you sad?" You asked him from afar and made your way closer to him.

It seemed like he didn't hear you clearly, so you asked louder, "hey! Why are you sad?" You reached for his shoulder, but it went through. Your eyes went wide, and you became terrified, "please, no." You glanced down at your hands and saw Shinobu walk past you, "she'll be alright boys, Kyojuro is with her." She dismissed them, and they went off to do errands for her.

Your heart skipped a beat at the sound of his name, "Kyojuro?" You whispered and took off sprinting into the mansion, "Kyojuro!" You screamed out and sprinted off to all the rooms where injured slayers would go, but you turned out to be in a private room. You found Kyojuro sleeping on your bedside in a chair. You looked over his shoulder and your body was laying there, all bandaged up.

There were tears streaming down Kyojuro's cheeks as he slept, "you should just let go of me." You whispered, and a voice came behind you, "please don't leave my sweet boy by himself." A woman placed a hand on your shoulder. You jumped at the touch, and it was a woman with red eyes with her hair to the side, "I- oba-san." You whispered out, realizing who it was.

Kyojuro's mom gave you a small smile, "it's not your time yet, please return to him." She reached for your hands and tears began falling down your cheeks, "I can't, I'm basically done for." You cried out quietly, glancing over at your body.

"Kyojuro and you are inseparable, watching you guys as kids, I knew you guys were for each other." Ruka placed her hand on your cheek, "please don't leave him right now, stay with him a little longer." She pleaded, and you nodded your head hesitantly. "I will." You hugged her quickly and your eyes opened quickly.

You looked around and felt around your body frantically, "I'm alive!" You sat up quickly and Kyojuro woke up at the sudden movement, "(Y/N)." He quickly embraced you and tears began flooding in the both of your guy's eyes, "Shinobu was right." He croaked out, and you pulled away from him looking into his eyes, "I saw your mom." You confessed, and he looked at you blankly and broke into a smile, "I'm glad she visited you, I've been praying to her every night." He grabbed your hands and Shinobu entered the room, "(Y/N)! I'm glad you're awake." She stood at the foot of the bed, "the injury the demon did to you wasn't that bad, but he did take a good chunk of your side. Luckily, he didn't hit any vital organs." Shinobu smiled, "you should rest some more, you're welcome to stay for as long as you want." The butterfly hashira dismissed herself. The two of you watched Shinobu leave, and the room fell back into silence.

"Let's fall back," Kyojuro broke the silence, and you looked at him. "Huh?" You gave him a, "what did you just say?" look, "let's fall back from the front lines, let's get married." Your eyes widened at his words, "I- are you sure?" You questioned, and he held your hands in his, "ever since we were little, I've always wanted to live my life out with you by my side with our little family." He proposed, and you jumped on him to go into a hug, "I'd love that." You pulled away and Kyojuro pulled you back into a kiss that he's been longing to give you.
