A/N: Writing start: 4/20/21, Let's see how long it takes me to finish this. Honestly, I don't have high hopes. Anyways, after rereading the last chapter from an outsider's point of view and trying my best to not be biased, I concluded that there are two major problems with my writing: Character depth and how long scenes take. I usually make scenes flash by like Usain bolt running away from the house from "Get Out" (The Flim). Anyways, here's the chapter kiddos. Buckle up since Mama Muzan (probably) comes in this chapter [For her visuals, muzan had a female form, simply look it up on the wiki or other places.]

Disclaimer: I don't own demon slayer nor have I claimed to own it, if your dumbass thinks that I am claiming to own it, I suggest you get a mental evaluation.


Tanjiro proceeded to ascend the mountain, eliminated some small fry that didn't demand being mentioned, he had expected there to be mostly weak demons but not demons that stood no chance against a Tsuguko. The thing is, when he entered the mountain, he smelt the somewhat sickening and disgusting smell of a moderate demon, the types he expected to meet on this Mountain.

'Must be an unpurposefully strong demon, Kyojuro said that most if not all demons on this mountain had only eaten 3 or 5 humans.' Tanjiro thought to himself, turning his attention to where the smell continued to originate.

He sighed as he started to walk. 'I have to make sure none of the basic trainees don't get hurt because they weren't prepared for a moderate demon.'

Slowly moving through the green shrubs that littered the ground and slapping low hanging branches out of the front of his face. He slowly made his way towards the strong smell, cautiously. He could never be sure whether or not his sense of smell could fail him and if there would be a demon waiting to hop out at him once he lowered his guard.

Taking several slow steps through a particularly rocky part of the ground. He heard the undeniable sound of a part of the rugged and solid ground shifting and buckling under someone's weight and the snap of a branch as a demon launched itself through the foilage and towards Tanjiro.

Sidehopping, he steadily dodged the tackle of the demon. Unsheathing his blade.

He took a long breath as the demon who just ate rocks slowly raised itself onto all fours and a defensive position, slightly growling.

'No stupid and overzealous statement about how I should just let them eat me as I was going to die anyways?' Tanjiro thought. Every single demon had said some variation of the corny and generic statement since he had begun ascending the mountain.

Keeping his blade in an offensive position, but more to retaliate if the demon were to assault Tanjiro.

"Hey, do you know a way to turn a demon back into a human?" Tanjiro asked with his now signature comforting smile. Sadly, his only answer was a growl. His smile didn't falter, his eyes slowly filling with pity. But not the kind type of pity. "Well, that's too bad" He muttered under his breath, "I got places to travel to." He finished " First Form - Unknowing Fire." He sprinted forward as his sword combusted in a storm of blue-white flames, in a flash he had swept past the demon, his blade cleaving straight through. Unlike in another universe where he would've stopped and prayed for the demon. He continued to march through the forest with his flames, throwing all his previous caution to the wind. He had already wasted enough time.

He marched through the more bushy part of the forest into a much thinner one, the atmosphere being much denser compared to the lesser scents he had smelled since entering this mountain. Though still pretty clean compared to the median.

He had begun catching glimpses of the demon through the forest as he approached, now finally getting a full view of what it was doing. It was now fighting the stoic woman with a fox mask, her stoic expression had dissolved into one of rage and despair. Her muscles tensed and her jaw had morphed into a grit.

He sighed as he approached, the was little to no foliage around this area so it's pretty easy to discern the scenario. She was laying against a tree trunk and her mask was slightly cracked, apparently instead of using it to break her fall. She took the brunt of it. Though, remained conscious. There was also a person running away, which he guessed was saved from the arm demon. How shameless.

The Demon had multiple hands and forearms surrounding its main body and head. It may make it tougher than usual but couldn't compare to refined breath style users. It had one of its arms extended in a downwards arc, most likely the one that had hit the woman with an ocean haori.

Jumping onto a tree diagonal to him, preparing to launch himself off it and send him piercing through the sky and to the head/neck of the demon, he opened his mouth. "SIXTH FORM - TURBULENT FLAME SPIRAL!" He announced

Twisting his waist and shifting his footing, he threw himself into the air while twisting and shifting violently, causing him to slash in a sort of vortex/spiral as blue flames erupted around him.

The arm demon had barely noticed this as his head fell off. The searing flames cutting through his neck like butter as Tanjiro landed his midsection and ran off of him. Twisting his waist and he jumped off so he could face the demon.

Looking with eyes mixed with disgust and pity. Disgust at the fact that this demon had given into its primal desires to consume human's blood and flesh, its own kin. And pity that it had been subjugated to that type of fate by the heavens. The disgust part is a regular sight to see dying demons. But the pity was... new, foreign to say.

'I'm... sorry, big brother, I'm so sorry for what I've done.'

The arm demon thought as the remains of his body finished disintegrating. Leaving no time for the demon to shed a tear.

Tanjiro slowly untensed his muscles (although still considerably tense compared to the stoic woman), both the stoic fox woman and the kid that had been able to watch the blue fire show.

He waved off his disgust and turned towards both the kid and the woman with a fox mask. Gripping the side of his haori and pulling it upwards, letting the wind carry the haori gently as he slowly sheathes his blazing blue katana and letting the blue trials of the haori settle. (A/N: I'm not gonna go update the prologue chapter but the general color scheme of his uniform is black and blue. Basically imagine an inverted [color-wise] version of Kyojuro's, red being replaced by blue and white being replaced by black.)

Walking over to the woman with the mask of a fox. He extended a hand to help up her, which she accepted. Taking a few steps back after helping her up, he took a note of his surroundings. A relatively barren part of the forest with no foliage, only trees. He looked over to the kid that the fox-masked woman had saved. Which of was simply staring at me in awe. "H-how did you do that?" He finally asked as he noticed that I was staring at him.

"Tsugukos usually train harder than the average trainee." He said blandly. "Now, do you guys wish to form a team with me for the time being?"

The boy immediately nodded, he wasn't going to pass up this chance for a free ticket on passing this test. The Woman with the fox mask nodded hesitantly after a minute or two of thinking.

"Alright, let's go then!"

Day Two of the final selection: Not much else had happened, just some lower demons hunted. Passed in a relative Hinch.

Day Three through Six: The same as Day two.


This was the last day, it was relatively easy to get through as lower demons stood no chance against him. He'd racked up his team's total kill count as 33, and personal kill count as 15.

Taking a sharp whiff of the air in relaxation as he sat against the hard bark of a tree trunk. He had parted ways with the Fox masked woman on day 4 since she said she was fine. The boy had gone stalking back down the mountain believing that he could survive. He left on the fifth day so he wouldn't be surprised if he didn't or did.

Which left him, he stayed in the midsection of the mountain and helped some people by hunting down a good amount of demons that were chasing them. Some stronger and more cunning than others but nothing necessarily to be proud of about slaying if you were a Tsuguko.

Continuing his whiffs of cautious relaxation. He slowly stood up in surprise as the hairs on his back began to stand up. Gripping the hilt of his blade and slowly unsheathing it.

The area he was in right now had little foliage and tall trees. Relatively similar to the area he had fought the arm demon in.

Focusing on his sense of smell. He tensed at the strong smell of blood entering his nostril from the left side. Quickly turning he spotted a whip of blood in the air, and then solidify.

Jumping and then twisting diagonally in the air, he slammed both of his feet onto the tree trunk and launched himself away.

Rolling and spinning to see where the attack came from, he saw a horned female demon with snowy white hair in a red kimono with a fluffy fur collar and a hesitant expression as she landed. Bringing her eyes up to stare at him. She had red eyes with very light pastel blue irises. (A/N: Alright all you need to know is she's Mukago lower moon 4, ok good?)

Her arms and fingers were dripping with blood as the wounds slowly sealed up.

Not wasting any time as he snapped out of his daze of scanning her. He quickly got into a dash posture and tensed his breathing. "First Form - Unknowning Fire." He muttered as he bolted over towards her with an open slash stance.

Before he reached her, he felt the ground in front of him slightly shift before a wedge forms right in front of his foot, causing him to slip forwards and nearly end up with a face full of red spikes. He was barely able to not get impaled by immediately shifting his wrists and moving his sword in a U shape, slamming the left flat side of his blade onto the side edge of the spikes before twisting his waist and push the blade furiously. Launching him away but without getting his stomach lightly slashed.

'Shit... I was too rash.' Tanjiro thought aimlessly as he rolled on his stomach, quickly hopping back on his feet and bouncing back.

The demon had slashed down its forearms, sending another whip of non-material blood.

Pointing his blade horizontally. "Fourth Form - Blooming Flame Undulation!" He screamed as he slashes in a 380 area before stopping to stare back at the demon.

He quickly began to sprint. Tensing his face he began to breathe in and out sharply in swift pulses. 'Blood. Infront.' He quickly rolled to his left, dodging the area that had just been engulfed in spikes.

The face on the demon's face had become fearful as Tanjiro began to approach closer and closer to her. Clutching her hands inwards violently, drawing blood from them and then whipping them violently outwards towards Tanjiro.

The Blood solidified far away from Tanjiro so that he couldn't slash it away. Tanjiro simply dodged it by moving to the left. Now approaching to her far right.

There was a good pool of blood under her so he couldn't get close unless he boiled it off first. Slashing and dodging occasionally as he began to circle her. She was pooling more and more blood under her.

"P-please stop, I-I'm getting d-dizzy." The She-demon spoke out. He could tell that this demon was much different, 'That blood... a blood demon art?' The smell she had was aswell much stronger, potent, and nothing to mess around with. He could tell she wasn't going at her full capacity.

"Do you know a way to turn a demon into a human?!" He yelled out as he continued circling her, blocking, slashing, and dodging her occasional attacks.

She simply shook her head as she continued attacking him.

Finally having enough. She slowly began to speak.

"Blood Demon Art: Iron Blood Control."

She sent another blood slash from her hand, but this one was different, it was physical and acted as a whip.

Immediately he raised his blade to block it, the whip making a snap sound as it wrapped around the blade.

He quickly began bolting towards her as he tugged at the blade, twisting his wrist downwards so the blade tip faced the ground as he approached the pool of blood surrounding her, he twisted his waist at a 360-degree angle, resulting in the demon being pulled towards him, causing her to lose balance as she tried her best not to trip.

Clasping his blade hard. He ran at her, quickly thrusting the tip of his blade into her left eye. Of which she responded by screaming violently and using his gut as a jump board to pounce away. Grasping at her eye.

He, whose blade was now free from her whip's pressure grip, was sent backward, still on his feet but hacking up blood. As he recomposed and recovered, he unwrapped the now limp blood whip that had been torn away from the demon's hand due to her jumping back. His blade now free, he sprinted towards the demon who had just recovered from getting her eye cut straight through.

"First Form - Unknowning Fire!" He said, bolting once more. This time hitting the demon but not on the neck. He slashed straight through her right arm, which she sacrificed to save her neck. The blood spurting from the arm quickly solidified into a spike as she screeched and gritted in pain.

She bent backward, going low, and sent several thrusts towards Tanjiro's gut.

Tanjiro, having just slashed her arm off. Quickly twisted his waist to the left, half dodging them but getting his previous slash wound from the spikes being reopened and deepened.

Gritting his teeth, he spun the katana in his grip as the demon finished her barrage. Pointing the blade straight down at her neck, he slammed it down, missing as she retreated her neck with a large amount of force, causing her to buckle her back slightly.

'Perfect!' Tanjiro Thought

"Fourth Form - Blooming Flame Indulgation!" He yelled out, gurgling slightly due to the blood that rested in his mouth along with a pool of saliva. Raising his blade diagonally, he shifted his weight downwards, slashing in an arc as he twirled.

She immediately went lower and buckled backward further to dodge, which was partially successful, though at the sacrifice of both of her eyes, rendering her blind for the time being.

She immediately jumped back, Tanjiro wasting no time and jumping into the air, furiously twisting his waist and screaming "Sixth Form - Turbulent Flame Spiral!" Slashing in a spiral while being launched towards her.

'Shit!' She immediately raised her arms, slashing her neck and screaming "Blood Demon Art: Bloodletting - Death Protection!" The massive amount of blood leaking from the large gash on her neck solidified just as the spiraling Tanjiro had just reached her neck, slashing through a good half or even 3/4s of her neck before the blade became stuck in the solidified blood.

Immediately bending his knees inwards, Tanjiro landed and raised his left foot, attempting to swipe the demon off her feet unsuccessfully, as she kicked him off and immediately begins running, regenerating her eyes and neck.

"Fifth Form - Flame Tiger!" He sprinted after her, raising his blade as it combusted into a blue storm of which morphed into a tiger that roared violently as it sped through the wind.

'Shit shit shit! I'm going to die! I'm going to fail Muzan!' The Demon screeched inside her mind 'She saved me for what! To die silently in the final selection to someone who isn't even officially a demon slayer?!' She began to sob as Tanjiro closed in, the spikes and whips she made being slashed and dodged.

She eventually stumbled and buckled in the pain of regenerating and the exhaustion of the fight. Tanjiro jumping over her with his blade ready to slash her neck off.

'I can't... I haven't reached my limit... I haven't been accepted by Muzan.'

*Epic Mukago Flashback*

There laid a black-haired girl with pale white skin, her body covered in beads of sweat, dressed in nothing but bandages that wrapped around her private areas and breasts. And from her wrists were rivers of crimson liquid being let into a bucket where already sizeable pools stayed.

'Why is it so cold? It's in the middle of the summer...' The girl thought as the blood dripped gently from her wrists. Her eyes closing gently. As several more drops ticked into the pool, her body slowly warmed as her legs and arms went numb.

'Huh... I thought it felt cold for a moment there... must be the dirty blood getting to my mind and soul again.' She thought as her mind was slowly strangled and deprived of oxygen, it slowly shutting down.

As her eyelids flickered. She saw the sight of a figure standing over her, going into shock but being too numb to do anything

'Is he back already?- Not again... I'd feel better if the disease just took me...' "take me already..." She let out in a whisper.

Who really stood above her was a pale woman with dark as night hair and crimson red eyes. Her lips were painted with a matching crimson.

"Take you? I was thinking of doing the same thing, I'm glad you agreed." She said, bending down on her knees and sitting comfortably. She then moved her right hand over to the lady's neck, slowly pressing her nail into her neck, and began to inject her blood.

From there on out, she was gifted the title of a lower moon, a powerful title, but she could care less about the title itself. Muzan, the lady who had saved her. Was the only thing she was interested in. She was stuck in that disgustingly dim room with only a male doctor who came to "check" upon her and once she got too sick, they began bloodletting. She thought for sure that she would finally be able to go back out into the sun and outside. But of course, learning from Muzan, the shogunate was anything but intelligent regarding medical procedures.

But she had stagnated ever since 1868, the last time they were allowed to openly hunt. They had switched to mainly hunting down hunters and being scared of dying after achieving such a fun life and without even confessing her love to Muzan. She had shied away from trying to killing any strong hunters, only eating small fries that came upon her path.

Not to say the obvious but she severely disappointed Muzan, who had begun to think that the lower moons were useless. Until she had gone to an isolated and snowy mountain. When she came back, she had interesting tasks for each and every one of the lower Moons. Lower Moon 1 through 3 hunted down former Hashiras namely Urokodaki. She was sent to monitor the Final selection by Muzan securely transporting her through the wisteria, Five was told to use his family to divert the attention of the Demon Slayer Corps towards, and Six was sent to help him. They were also told to watch for a "kid with hanafuda-like earings" and if possible, kill him. She was indeed watching out for him but with the way even Muzan, The Queen of Demons, Originator of all modern demons. Had spoken about him, she couldn't help but atleast be shivering when she found him. Which she had been.

The fight progressed oddly, very still and motionless compared to what she expected to be a very fast-paced and violent fight. It mostly took place in a general area instead of both of them moving throughout the middle section.

The Boy had difficulty taking her down but it was nothing that couldn't be fixed. Reflexes, taking advantage of the situation and general power, and refining his techniques.

But nonetheless, he proved strong enough to slay her. Her own performance was lackluster as she deemed it. She had gone too easy at first and only got serious when he had already gotten her into a bad position in the fight. She could've stood a much better chance if she was more confident.

That's why she calmed down considerably as she felt the heat nearing the back of her neck become boiling. Feeling that she was prepared for anything to happen, whether she died or lived.

"Blood Demon Art: Impregnable Immunity!" The Demon screeched as every hole in her body had begun to spout out massive of blood as it began to twirl around her. The Blue flames nearing her not even causing the blood to curl or boil slightly. The smell of the blood was much denser and stronger. Causing Tanjiro to stop his sprint, slammed his feet into the ground like brakes and then pouncing backward, placing the hilt onto the left side of his hip and facing the right flat side towards her, tensing himself into the defensive position. He was right on time since the area around the demon erupted into a wall of a metallic red material, isolating the demon from any dangers.

'Shit!' He quickly scanned the area for openings, there were none. The only way in, and it was going over.

Lucky for him, this area had tall trees, sprinting over to the nearest one. He quickly began to scape the bark and climb onto it, eventually reaching one of the tallest branches and allowing him to jump in. He saw the demon staring into the canopy in front of her with her arm extended like she threw something. Not wasting any time, Tanjiro leaped towards her

"Fourth Form: Blooming Flame Indulgation" He yelled as he leaped, twisting his waist as he got into the range, slashing her head right off.

Landing with his mouth in the dirt. He slowly twisted into a comfortable position.

He laid there resting, not noticing the night-black-haired woman in a red and black kimono slowly approaching him and her disintegrating moon.

Muzan had been waiting patiently in her castle for any information regarding the one Kamado that had gotten away.

When she murdered the entire kamado family. She couldn't find those damn beautiful hanafuda earrings anywhere. And the woman knew for a fact that those damn stubborn kamados wouldn't dare lose those. So that meant that one of them left before she had come. What fucking luck.

One of her demons had found the Kamado's hideout the day before and she wasted no time. She wanted their heir as soon as possible so she could groom him into the proper perfected being.

She had failed all the other times since she only met them when they were all strong enough to escape at the very least. And this was the first time she could've gotten them before they ever even started to grow.

She killed all of them and turned one of them into a demon as an experiment in a fit of rage.

Anyways, as soon as she escaped the mountain, she telepathically sent orders to each of the lower moons and told them what the other lower moons were doing so they understood the situation. But she had only one demon in the final selection, something she wanted to change several days since the death of a certain arm demon, but alas. It was too late for it to be changed.

She immediately dismissed all of the other lower demons from their duties and told Mukago to look for the person who wore Hanafuda-like earrings.

And now, she waited patiently for Mukago to slash the two organs of hers she had given to the lower moon. She knew she had encountered the Kamado but couldn't just go sprinting, she had to wait for Mukago to realize she couldn't survive on her own. But to the demon queen's frustration, she just refused to summon her help until she knew she was going to die.

Finally, she could meet the person she believed she was destined to live with immortally as perfected and unchanging beings.

His eyes were as wide as stars as he stared into the crimson scleras of the queen of demons. Her scent was so incredibly dense that it felt light to be at the center of it yet with a hint of overwhelming familiarity.

'Why is... Who is this? For such a dense scent, she must be Muzan. But she's a woman?' He thought 'And so beautiful...' He snapped out of his daze, rolling away from the demon and immediately flinging himself upwards and landing in a defensive position.

'Now or never!' He sprinted towards her, slashing in a large arc. He was exhausted and unable to use any breath styles, he knew it was impossible to win. But if he didn't fight, wouldn't all his sacrifices go to waste?

She effortlessly dodged the poor attempt at her life. As he stumbled. She grabbed the back of his haori and demon slayer uniform and yanked him back into her.

As he fell into her, he felt like he was laying against a diamond wall. 'So damn hard...' (A/N: let's be honest, we would be too if we fell into the holdings of mommy muzan.)

Tanjiro felt his blade being removed from his grasp as the woman yanked it away and threw it to her right. Wrapping her arms around his own and hugging him tightly into her ample blossom.

"Finally, I have you. You aren't perfect right now but if it takes a little change to meet the mantle and tip of that man, then change you will." The Demon muttered softly into his head just loud enough for him to hear her.

Hearing this, Tanjiro who was struggling to escape her grasp, became confused. As any insane man who was in his conditions would instead of enjoying the ample blossom of the woman, the little late bloomer fucker.

She raised him to meet her face. "Sadly, we must meet at a later time." She finished before kissing him.

Tanjiro, to say the least, was freaking out. He could feel her tongue expertly breaching past his lips as saliva and another irony liquid invaded his tastebuds.

Sadly, he did not have much time to be confused as he started convulsing. Noticing that the coppery/irony liquid that he had tasted was most likely the blood of the woman.

"I hope you enjoyed my gift. Ka ~ ma ~ do ~" She hissed as she left him convulsing silently due to the blood she injected into the teenager.

Next Chapter: Who the fuck is Mommy Muzan?

Actual Next chapter: Intermission.

A/N: I did not want to cut it off here but decided it would be best. Cliff-hangers and all.

Muzan mommy will only act like mommy muzan with Tanjiro, otherwise, she's the same Muzan from canon as you may have been able to guess. (Just be happy that I'll save you some braincells) As for the part where she fed Tanjiro her blood. He won't become a demon. Right away atleast. I liked the idea of Kamado being resistant to demon blood from 1angel2heart's abomination of fanfic so I added it here. I must again credit her for mommy muzan and I suggest if you want a dose of degeneracy. Go read her fanfic of Tanjiro being anally raped by Muzan (Honestly pretty good fanfic to read.)

For now, Tanjiro will simply have some minor demon shit like enhanced regeneration and the voice of Muzan telling him to bone her and shit like that.

other than that. I like to talk about two things aswell related to my fanfic. Firstly: I do not entirely trust myself with this fanfic, I would like for someone to take the base plot of Kyojuro being the one to meet Tanjiro instead of Giyuu. So anyone who'd like to do that, feel absolutely free to do so, just if you take anything else other than that credit me. But I doubt you'd wanna take "mommy muzan" so.

Secondly: I need a playlist of music for writing. please pm me some music to play while writing. ty.

Other than that, there's nothing else to speak of. I hope you enjoyed my piece of writing, review if you want to. goodbye.
