A Demon-Slaying Curse?! (My Sakuna AU in KNY)

Ch. 1 - A Demon?? No! no! I'm a Curse!

*Takara's P.O.V*

I woke up in my new world, saddened by the loss of my husband, but I took a deep breath, deciding to move on as I know that Sakuna wouldn't want me to grieve. Yuji might, but... I believe he will understand. "Yuji, Sakuna... I promise... I'll make sure our sweet prince grows to adulthood." I murmured, placing one of my four hands on my belly. 'Curses don't really get pregnant, or, at least, that's what I thought at first... But... After that wonderful night with both of them, I found myself carrying their children. Yuji's was now five, and was as strong as him. Sakuna's child, however, was taking their time, but, in a world this new and scary, who could blame him?' I thought, and stood up before going outside where I found Hiroki, Yuji's son, training with boh his cursed energy, and the sword I had bought to see myself. "Hiroki! Be careful, please! We don't know how your energy will react to that sword!" I cried worriedly, and he nodded in understanding. He was a spitting image of his father, but he had my silvery-gold eyes with speckles of Sakuna's red and his father's light brown eyes. He also has four arms, a trait that I was born with as a mortal before I became a curse. "Yes ma'am! How is my younger sibling doing?" Hiroki asked, and I smiled. "Ryuu is doing fine, but pay attention. One. You're holding the sword wrong. Space out your hands, and switch your left hand to be below your right. Second, keep your feet a shoulder's width apart. And, third, keep your attention on your opponent, even if you're talking to someone else." I say, and he immediately follows my instructions, adjusting his stance and his hands to my words. I then began to instruct him on how to use it, making sure to teach him exactly how I was taught.

*Five Years Later*

"I'm going now mom! I'm going to make Dad proud! Let me know how Ryuu is doing in his training soon, alright?" Hiroki called, and I nodded. "Of course, my little Sorcerer! Let me know when you get in!" I say, and he nodded before running off to the Final Selection for the Demon Slayer Corp. "Oh my, how you've grown, my minature Yuji. Your fathers must be so proud!" I murmured, standing in the doorway of our home, and Ryuu walked up to me before holding my hands with his. "Mama? Where is Onii-san going?" Ryuu asked, and I smiled. "He's going to the Final Selection, where Trainee Demon Slayers become apart of the actual demon slayer corp. It's a very honorable job, and I hope that, once you finish your own training, we can enter the same group together with your Onii-san and defeat demons together." I say, and he smiled before trying to lift up the sword that Hiroki always used to train with. 'I got him a heavier katana for his final selection exam, but I can only hope that he passes. He's only a mortal after all.' I thought, and then gave Ryuu the first training sword that his Onii-san used before beginning to train with him.

*Time Skip - Five Years Later*

As soon as we had sold our house and all of our belongings aside from some few precious items, we headed to the final selection, where we made sure to hide our extra two arms before heading up the staircase. "Welcome all to the final selection." Two girls said, and then explained everything before we all shot off into the forest, with Ryuu and I using Negative Energy as our guide to find the demons and slay them easily, showing them just how inferior they were to us curses. "Good job, Ryuu. Your father would be proud." I say as he butchers a demon with his bare hands. "No problem mom. Dad was powerful, and I hope that I can fill in those shoes one day!" Ryuu stated, and I chuckled before we talked and chatted for the rest of the time, making sure to kill as many demons as possible. "Oh my... Mom, look at this guy!" Ryuu whispered, and I looked over to find a man with red hair and eyes bearing a scar on his forehead. There was just something about him that made me blush, and I knew Ryuu saw it as I watched the man fight a massive demon, enraptured by how handsome he was even at his age. He was almost as handsome as Yuji was when he was Sixteen!!! Then I noticed something... Something that made me angry. 'that blasted demon is getting handsy with my new future king!!! Imma rip this bitch apart!!!' I thought angrily, and bolted forwards, stopping the demon from attacking the man that I was watching in pure, unbridled anger. "HEY!! LAY OFF, FUCKSHIT BITCH!!" I roared, and, out of nowhere, several curses came to my aid, attacking the demon in blindsided anger as I began to control them with my cursed technique, called 'Cursed Eyes'. Basically, I can control and create curses from my eyes alone if I wished, which is what I'm guessing I just did since these ugly, vile curses appeared out of nowhere. "Thank you, but I'll take it from here!" He said, lunging forward, Katana in hand. 'I don't know if he can see my curses or not, but... Seeing as demon slayers had different techniques according to their breathing, if he can, he must think they're my breathing technique... Oh if he only knew.' I thought, and then rush forward and proceed to rip and shred every single hand that dares try to get near the man I hoped to ask out after this fight to utterly useless shreds. "Oh my, you're quite violent!! Are you sure you're not a demon?" The hand demon taunted, and I blew. Up. "NEVER COMPARE ME AND MY FAMILY TO SUCH SCUM LIKE YOU, BLASTED CREATURE OF THE DAMNED ONE!!!" I snapped in pure anger, and my son immediately joined the fray, protecting me from the hand demon's assault as I began to summon more curses and whatnot to combat this menace, but specifically ordering them not to mess with the boy with the red hair and my son. "W-WHAT ARE THESE THINGS?!" the hand demon said, and I smiled. "Physical manifestations of negative human emotions... Better known as Curses. Quite common from where I'm from, and it's unlikely you'll survive... After all... You demons are absolutely brimming with the cursed energy that my sweet little curses crave!!" I say insanely, and, in that very moment, the boy I had fallen for at first sight cuts off his head, but, before he can even fade away, my curses suck up all of the cursed energy in the demons corpse before returning to me, merging with my body as I walked up to the boy with my son following me. "Ah! I'm Tanjiro Kamado! I appreciate your help in distracting that demon so I could cut his head off." Tanjiro said, and I blushed softly at the name. "I'm Takara Ryōmen-Itadori, and this is my youngest, Ryuu Ryōmen-Itadori. It's nice to meet you Tanjiro. And please, don't mention it! However... I was wondering if you had a place to stay? My son and I sold our house as we couldn't afford it anymore. All we have left are mementos of my late husbands. They were twins who did everything together, so I married both of them." I say, and Tanjiro smiled happily. "I'm sure my master would happily let you stay until you and your son's swords and uniform arrives! But... Um... You seem a bit red. Are you alright??" He asked, and Ryuu giggled. "Mom's been looking for a suitor for a while, and I honestly think she loves you, Mr. Kamado!!" Ryuu said, and I blushed even harder, covering my son's mouth. "eh? Oh, um... Well... Uh... I don't know you very well, but I'm willing to get to know you before we decide on anything serious, Ms. Ryōmen-Itadori!" Tanjiro said, and I smiled. "Please, call me Takara. And... Um... That is perfectly fine by me. I wouldn't be able to live with myself if I forced you to be with me." I say, and, this time, it was Tanjiro's turn to blush slightly. "well, it's day six now. Let's start making our way back to the Wisteria grove while slaying some demons." I pointed out, and Tanjiro nodded in agreement as we all began to walk towards the Wisteria grove.

*Time Skip - End Of Day Seven*

After we got there, we found out that we were the last ones out. Tanjiro was carrying Ryuu, and we had honestly learned so much about each other. I had entrusted him with the knowledge of me being a half-curse, and having four arms, and he had entrusted me to the knowledge that he had a little sister who was a demon, and he was trying to turn her back. We had also agreed to at least try something between us, but, if it didn't work out, we would just remain friends. "Ryuu, wake up!" Tanjiro murmured, and Ryuu yawned before waking up as I smiled at my now-boyfriend and my son, and Tanjiro looked up at me as he sat my nine-year-old prodigy down. As soon as we got our ores, and our wisteria stamps, our uniform measurements came up, and Tanjiro cast my son and I worried glance as we stepped up to get our measurements done. "Um, pardon, but um... My son and I have a genetic condition that causes us to have four arms, and we were wondering if it was possible to have four sleeves put into our uniforms to make it more comfortable for us?" I asked the girls, showing my arms, and my son waved happily as the girls looked on in surprise. "Oh my! I assume you were born like this? As a demon wouldn't be able to even come anywhere near this place without being severely weakened, I have to assume that you're both human, correct?" The girls asked, and I smiled. "That is correct. My eldest took the final selection five years ago, and now we've come to join him. Honestly, demons are a menace." I say, thinking of the demon that nearly killed my son. "Well then, yes, we can put in a special order." The other girl said, and I thanked them before we got our measurements, and then left with Tanjiro.
