Haiiii :3 

So, recently in my English class we have been looking into AI and stuff like it's ethics, etc... I found the subject really interesting, so I wanted to try to give it a go in my personal works. I'm going to give it a prompt and see a few things that it creates.. I'll probably add some commentary and stuff too lol.. I think this is a fun and funny experiment, because the AI's accuracies are.. questionable, to say the least. I want to see how it characterizes Kokushibo and Muzan and how it creates a story. Thus far with what it's written in my class, the AI tends to try to overdo stuff and be overly dramatic, so I wonder how it will do with fluff lol. 

The prompt I gave it was; "Please write a romantic, silly and fluffy story between the two demons Kokushibo and Muzan from Kimetsu No Yaiba. If possible, please pull inspiration from the fanfiction "[Kokuzan] - Oneshots, headcannons, etc!" by FanficSnail on Wattpad, but don't directly mention the fanfic. Please make the fanfiction 550 words or less, and leave a word count at the bottom."

Let's see what it creates! 

----------------------------

In the realm of demons where shadows danced, and darkness reigned, there existed an unconventional pair: Kokushibo and Muzan. While their existence was entwined in bloodlust and power, something peculiar blossomed between them. (Cute, but as I kinda said, I feel like it's overdramatic?? At least it's vocabulary is trying to be too sophisticated...) 

Muzan, with his regal demeanor and commanding presence, ruled over the demon world. His elegance and sophistication were unmatched, yet his heart had a soft spot for Kokushibo. There was an undeniable allure to the silver-haired demon (Koku does not have silver hair what 😭😭) - a gentle demeanor that contrasted the ferocity of his battles. (Not really.. but also, I guess? I wouldn't exactly describe Koku to have a "gentle demeanor" unless he's with Muzan, but go off ig) Kokushibo, in turn, admired Muzan's prowess and brilliance, finding solace in the mutual respect they shared. 

Their interactions were a blend of romance and whimsy, hidden away from prying eyes. Amidst the chaos, they found solace in stolen moments, secret trysts that defied the norms of their world. (I don't even know what "whimsy" and "solace" mean 😭) 

One moonlit night, Kokushibo awaited Muzan's arrival in a secluded glade. The air hummed with anticipation as Muzan appeared, his crimson eyes ablaze with desire. Their gazes met, each conveying a silent understanding that transcended words.Muzan's voice, smooth as silk, caressed the stillness. "Kokushibo, my dear, you enchant me with every passing moment." (Erm.. actually 🤓👆 dialogue should start in a new paragraph) 

A faint blush adorned Kokushibo's pale cheeks as he replied, "Your praise humbles me, Muzan-sama. But it is your brilliance that captivates my very essence." (Koku here is talking a bit faster than normal..) 

Their dance of words was a prelude to the unspoken desires that swirled between them. Muzan's hand extended gracefully, drawing Kokushibo closer. Their fingers intertwined, a tangible display of their mutual affection. 

"You are exquisite, Kokushibo," Muzan murmured, his gaze unwavering.

"As are you, Muzan-sama," Kokushibo breathed, his heart racing with anticipation.

A playful smirk graced Muzan's lips as he leaned closer, their breaths mingling. "Shall we indulge in the forbidden, my dear?" (GIRL IS CHAT GPT ABT TO WRITE A SMUT???? That would be.. unexpected..) 

Kokushibo's response was a tender nod, his yearning palpable. Their lips met in a fervent embrace, a collision of passion and longing. The world around them faded into insignificance as they lost themselves in each other's presence. (We get it, you're special, now STOP USING WORDS THAT IDK THE MEANING OF 😭😭 WHAT THE HELL IS FERVENT 😭) 

Their love was an anomaly, defying the darkness that surrounded them. In their shared moments, they found solace, understanding, and a love that transcended their demonic existence.

As the moon dipped behind the horizon, casting its final ethereal glow, Muzan held Kokushibo in his arms, their connection unbreakable. (CHAT GPT IS ABT TO KIL OF THE GAYS 😭) 

"You are my equal, Kokushibo," Muzan whispered, a rare vulnerability in his voice. (WE KNOW. THEY'RE BUISNESS PARTNERS, THEY'RE MARRIED, MUZAN DOES NOT NEED TO SAY THAT 😭) 

"As are you, Muzan-sama," Kokushibo replied, savoring the intimacy of the moment.

In the quiet embrace of the night, they found refuge in each other, cherishing a love that defied the conventions of their world. (SO DRAMATIC. BITCH I SAID SILLY 😭)

Uhh so yah the first attempt was.. something. It was cute, but overly dramatic. I'm going to try editing the prompt a bit. 

The new prompt: "Please write a silly and fluffy story between the two demons Kokushibo and Muzan from Kimetsu No Yaiba. If possible, please pull inspiration from the fanfiction "[Kokuzan] - Oneshots, headcannons, etc!" by FanficSnail on Wattpad, but don't directly mention the fanfic. Make sure that the relationship between Kokushibo and Muzan is already established, so that they have been married for 400 years. Please make the fanfiction 550 words or less, and leave a word count at the bottom."

I tried adding the 400 years of marrige part so it's not like "You are my equal 🥺👉👈"  I also took out the word romantic to try to make it less dramatic and more fluffy 😭

----------

In the eerie embrace of the demon world, Kokushibo and Muzan's bond had stood the test of centuries. Married for over four hundred years, theirs was a relationship marked by both mischief and endearing moments. (We don't need the exposition but oki ig) 

One evening, amidst the whispers of the night, Muzan found Kokushibo in their shared abode, diligently practicing his swordsmanship. As Kokushibo lunged and parried, Muzan leaned against the doorway, an amused smile playing on his lips. (Okay I could see this yeah it's getting better..) 

"Darling, practicing your techniques again?" Muzan purred, his crimson eyes glittering with amusement. 

Kokushibo turned, a faint flush dusting his cheeks at being caught. "Ah, Muzan-sama. I simply wished to sharpen my skills. You know how important it is to stay prepared." (I feel like it's getting their general attitudes right, so that's good. However, it doesn't really capture Kokushibo's speech patterns) 

Muzan chuckled softly, sauntering over to Kokushibo with an air of effortless elegance. "My dear, after four centuries, I believe your skills are far beyond 'prepared.'" 

A mischievous glint flashed in Muzan's eyes as he plucked the sword from Kokushibo's hand. "But if you insist on practicing, why don't we make it a game?" (Huh..? Okay? Idk what this means by this... also bro just plucked Koku's sword from his hands??)

The challenge sparked a fire in Kokushibo's eyes. "A game, Muzan-sama?" 

"Yes," Muzan replied, twirling the sword with finesse. "Let's see who can land the most elegant strike on that practice dummy in the next minute." (Muzan is going to loose poor him) 

With a shared grin, they readied themselves. As the timer began, Kokushibo moved with the grace of a seasoned warrior, each strike a display of his expertise. Muzan, however, added his own flair, infusing every move with an almost theatrical finesse. (Muzan and his dramatic self 💁‍♀️.. I don't think he knows how to use a sword that well tho.. at least, no where near as well as Koku) 

The minute flew by in a whirlwind of movements, and when the timer ceased, they both stepped back, panting slightly, a competitive gleam in their eyes. (Demons don't get tired 😭😭) 

Muzan inspected the practice dummy, nodding approvingly. "Well, well, it seems we're evenly matched, my love."

Kokushibo chuckled, a rare sight that never failed to charm Muzan. "Indeed, Muzan-sama. A draw it is." 

Their laughter echoed through the halls as they collapsed onto a nearby couch, (WHY IS THERE A COUCH IN THE TRAINING ROOM???) the tension of the challenge fading into playful banter.

In the warmth of their shared laughter, Kokushibo nestled closer to Muzan, relishing the comfort of their bond. Muzan wrapped an arm around him, a contented smile gracing his lips.

"Four centuries and you still manage to surprise and delight me, my dear Kokushibo," Muzan mused, pressing a tender kiss to Kokushibo's forehead.

"And you, Muzan-sama, remain as enchanting as ever," Kokushibo replied, basking in the affection.

Their love had endured centuries, a testament to the depth of their connection, woven with moments of silliness and unwavering adoration. (Girl I told u that they were married for a long time and u made it the story's whole personality 😭)

That was better, but I think I want to try once more, with giving it a more specific situation/prompt: 

New prompt: "Please write a silly and fluffy story between the two demons Kokushibo and Muzan from Kimetsu No Yaiba cuddling on their bed in their room in the infinity fortress. If possible, please pull inspiration from the fanfiction "[Kokuzan] - Oneshots, headcannons, etc!" by FanficSnail on Wattpad, but don't directly mention the fanfic. Make sure that the relationship between Kokushibo and Muzan is already established, so that they have been married for 400 years. Please make the fanfiction 550 words or less, and leave a word count at the bottom. Please write this with more average vocabulary, but still use a few "complex" words here and there. Please also make the work more fun instead of dramatic." 

I basically tried to address all the things I didn't like and fix them within the prompt.. let's see how it will do! 

--------------------------

In the tranquil expanse of the Infinity Fortress, amidst the grandeur of their domain, Kokushibo and Muzan found themselves curled up on their lavish bed. After four centuries of marriage, their bond was a tapestry woven with affection and familiarity. (Again, don't need the exposition, and it's still a bit much on the vocab, but at least I know what everything means..) 

The room bathed in a soft, ethereal glow as Muzan reclined against the headboard, a contented smile gracing his lips. Kokushibo nestled close, relishing the warmth of their proximity.

"Ah, Kokushibo, my darling," Muzan purred, running a hand through Kokushibo's silver locks. (KOKU HAS BLACK AND RED HAIR NOT SILVER 😭😭 I think it's confusing final form Muzan with koku...) "Isn't this just perfect? A moment of peace in our eternal existence."

Kokushibo hummed in agreement, nuzzling into Muzan's side. "Indeed, Muzan-sama. These moments with you are the highlight of my endless days." (Ngl that sounds a bit depressing koku.. even tho it has good intention the "endless days" feels a bit dark to me ig..) 

A playful glint sparkled in Muzan's crimson eyes as he pulled Kokushibo even closer, reveling in the affectionate intimacy. "Tell me, my dear, what was your favorite memory from the past four centuries?"

Kokushibo pondered for a moment, his fingers tracing imaginary patterns on Muzan's chest. "Perhaps the time we attended that extravagant demon ball in the 17th century. Your elegance mesmerized everyone, Muzan-sama. It was a night to remember." (Real they'd definitely attend balls.) 

Muzan chuckled, a melodious sound that echoed through the room. "Ah, yes! The look on those demon lords' faces when you outperformed them in that impromptu dance-off was priceless, my love." (Girl I don't think Koku is a dancer... 😭.. also there's only one demon lord..) 

They dissolved into gentle laughter, reminiscing about their shared adventures and escapades across the centuries.

As the laughter subsided, a comfortable silence settled between them. Muzan traced idle circles on Kokushibo's back, relishing the closeness. Kokushibo, in turn, traced abstract patterns on Muzan's chest, enjoying the serenity of the moment. (Girl how does that even work???) 

"Muzan-sama," Kokushibo murmured, breaking the silence, "I am eternally grateful for your presence in my life. You bring light to the darkness that shrouds our existence." (Kokushibo again with something dark 😭😭) 

Muzan's expression softened, a genuine fondness in his eyes. "And you, my dear Kokushibo, are the anchor to my eternity. With you, every moment feels like an adventure, a joyful escapade."With a tender embrace, they savored the simplicity of their love, a bond that transcended time itself.

In the cozy haven of their room, amidst the infinity of their world, Kokushibo and Muzan found solace in each other's arms, cherishing a love that had weathered centuries and promised eternity. (WHAT THE FUCK DOES SOLACE MEAN OMG 😭😭😭)

I think this one was the best one, but it could still use some improvement. Overall, I think this experiment was interesting, and I liked looking into it, but I like writing my own things better. I think a human writer can understand the characters and dynamics better, as well as have mor accuracy than the AI. I think humans generally have a better tone/mood I guess? Like most (I'm assuming to be) human-written fluff is more fluffy in it's writing style than the over dramatic AI. I feel like it's going for the talented AO3 author aesthetic, but I still feel that actual authors do that much better. 

Anyways, this was pretty fun! I'm currently working on the next chapter for my other book, so expect that to come out soon! <3
