What If Yoriichi Became a Demon? (Demon King Yoriichi)

now we all know that muan is the Undisputed Demon King and because of him we have this amazing series we know as Demon Slayer meanwhile yorichi is undoubtedly the strongest swordsman of all time so have you ever wondered what would happen if yorichi became a demon scratch that let's think of something bigger what if yorichi became the Demon King surprisingly enough not much changes at the beginning of the story especially yuichi's history same as always yorichi was born in the middle of the soku period with his twin mikatsu tsugikuni with yorichi having a mark on his forehead that his father deemed as unlucky but this gave him the ability to see through the transparent world and as he grew up he met UDA an orphan who would eventually become his wife he was expecting a child but on his way home after trying to find a midwife he saw that Yota and their unborn child were killed by a demon he was so struck by this tragedy that for 10 days straight he did nothing but hold her corpse in his arms eventually this event was what led him to become a Demon Slayer and because of his Raw Talent he eventually became the strongest and mastered the sun breathing technique which gave birth to the five fundamental breathing Styles in one of his journeys as a Demon Slayer he saved sumiyoshi and suyako kamado tanjiro's ancestors and they became really good friends his most Fateful Encounter was with muan himself where he sliced and diced him up so badly to the point that he almost died and got PTSD mikatsu his twin eventually met with muon and he agreed to become a demon changing his name to kokushibo now as a demon kokushibo assassinated the oyakata the head of the Demon Slayer Corp and this is the Catalyst for the massive change in our story you could even say it's literally their Cannon event because of this betrayal the other demon Slayers demanded that yorichi should be the one to take responsibility for his brother's actions and commit zuku lucky for him though the new oyakata was merciful and decided that yorichi was to be spared and banished instead now this is where things get interesting you see in the original series yorichi continued on to independently kill demons and even kept in touch with some of the hashiras secretly but in this timeline yuichi felt betrayed and his sense of justice was slow slowly getting twisted he runs off on his own to hunt down muan and his entire demeanor goes from being warm like the sun to cold like the winter however before he committed to this Manhunt or demon hunt he met up with the kedo family One Last Time one of the few people he trusted the most and showed them the sun breathing technique sum Yoshi promises that he will keep the sun breathing technique alive through the hinokami kagura and realizes that this will be their last meeting as yorii hands them his hanafuda earrings as he bids farewell yorichi becomes the lone wolf that he has always wanted to be his Journey was long and he killed a lot of demons on his way as he finally found muan of course muan was outright terrified like imagine seeing the man who almost killed you appear right before your eyes once again the two fought and as you can tell yorichi easily made muan fall to his knees but instead of killing musan he tries to make a deal because of his deteriorating mental health and his outlook on the world becoming totally twisted and dark he decides he wants to become a demon to take revenge on the humans who treated him like trash all his life even though he was indifferent who un agrees because what can the guy do if he doesn't make yorichi an enemy he's dead so he gives yorichi a lot of his blood in the hopes that he cannot assimilate properly and die due to the transformation but surprisingly yorichi transforms into a demon and because of his hyper physical abilities he is able to instantly regain his Consciousness without turning into a total Beast muan couldn't be any happier because the one that he feared the most was now on his side or so he thought after yorii became a demon an upper Moon meeting commenced and he was instantly welcomed into the organization but with a lot of tension most of the Demons hated a new Powerhouse coming in because it would mean there's going to be a chance when it came to their rankings and no one knew this more than kokushibo himself the current upper rank one to test his loyalty and knowing their past muan came up with a little twisted game he orders yorichi and kokushibo to duel for the position of upper rank one without hesitation both agreed yoriichi remained nonchalant the entire time while kokosa was full of rage and anger the fight was fierce but it also ended fast because as we all know even an 80-year-old decrepit yorii almost ended Koko's life but couldn't do it because he died standing yorichi won and he's now the upper Moon one but he spares Koko's life in the process because he still has a little bit of compassion left inside him because of this course of events muan clearly thought that yorichi was completely loyal to him as by the looks of it yorichi was willing to put everything on the line just to gain power and this led muan to put his guard down one night yorichi requested a personal meeting with muan to supposedly discuss plans on how to kill the demon Slayers when suddenly he whips out his sword and tries to decapitate muon in one go luckily muan was able to dodge this surprise attack and went fullon Attack Mode he was panicking and scared because not only could he not look inside yuichi's mind but couldn't even activate the curse that comes with his blood yorichi took another opportunity to attack and the two clashed swords and Claws it was a fight to the death and muan couldn't comprehend why he wanted to become a demon first before he killed him it lasted a while but in the end muon was completely annihilated he tried to do the same trick where he blew himself up into tiny little pieces but it didn't work and yor finally defeated him the upper moons rushed to the room where the two fought and saw that yorichi was the only one left standing he declared himself the new Demon King and instead of trying to find the blue Spider Lily they will instead eradicate the demon Slayers the rest of the story stays the same and years pass by it was now the time of the taisho era and tanjiro kamado was born just like muan yorichi and the rest of the Demons had no luck in trying to find the headquarters of the Demon Slayer Corp on the other hand kokushibo was full of jealousy not only because he lost his spot as the upper rank one but he also became The Demon King and even he had no choice but to follow yuichi's orders as the demon second only to yorichi he continuously tried to challenge his brother but not once did he win and every time yorichi held back just to save his life with the news of yorichi becoming the Demon King spreading like wildfire and proof that demon Slayers could in fact become demons it led to a pretty catastrophic outbreak of betrayal cases among the Demon Slayer Corp low-ranking demon Slayers who have no loyalty to the core as well as those who were consumed by hate and treated unfairly by Society started flocking to the demon side side and this resulted in their numbers swelling up by the hundreds if not thousands but there's a disadvantage that comes with this as well you see the new demons are much weaker compared to those in the original series because these Freshies were turned by demons that were also turned by yorichi this means that the concentration of mu's blood is not at its purest resulting in lower boosts when it comes to physical abilities as well as more chances of a transformation going completely wrong another thing triggered by this increase in Demon Slayer demons is the fact that older demons or those who didn't come from any demon slaying back backg ground hated the newcomers because there's a stark difference in mindset and a lot more as the days go by and with the new demons outnumbering the old ones a civil war across demon society looks like it's going to be imminent because they weren't affected by the change that much and overall just respected the hierarchy the upper moons decided to align themselves with yorichi except for daki and Garo who felt indebted to muan as well as kokushibo who was the one that was secretly flaming up the revolution in addition the lower moons 2 5 and six joined the traitor side after kokushibo promised them more power once they had won a huge battle breaks out between the two insides just inside the infinity Castle hundreds of demons fight each other to the death tearing through flesh and Bone during this battle yorichi and kokushibo were dealing a lot of damage to their opponent's troops but it's pretty obvious that the rebels are at a complete disadvantage because they only had upper Moon one and upper Moon 2 the rest of the upper moons alongside yorichi were having the time of their lives and the rebels were relying on kokushibo the entire time to carry them to Victory however kokushibo made a grave miscalculation one that would cost him this entire battle and it was no other than nakame but why is she so important well if you weren't listening you would have failed to notice that nakame May's blood demon art is quite literally their entire Battleground yep just like in the original series nakame can control the infinity Castle itself and this gives the Loyalists an overpowered Advantage as the battle raged on the rebels were slowly losing their footing and kokushibo could only do so much in the end all of the traitors are killed except kokushibo who successfully escaped before they were surrounded now you might be wondering why doesn't yorii just chase him since he is the demon king and must know where every demon is well it's because he doesn't have Moon's demon manipulation which allows him to tap into the thoughts of other demons this is also the same reason why he couldn't quell the Rebellion before it went way out of hand even though he managed to run away kokushibo is severely wounded and his regeneration couldn't keep up with the wounds he suffered from yuichi's Sun breathing this is interesting to know because Sun breathing is the only breathing technique that can limit a demon's regeneration and since yuchi was the one who created it well you already know it's potent as heck he keeps running and running and eventually ends up in the middle of nowhere in the mountains as he keeps moving by pure coincidence and by my omnipotent Powers he eventually ends up at the kamato household and meets tanjiro who is standing outside of their home performing the hinokami kagura now seeing a demon for the first time tanira was scared out of his pants and had no idea as to what to do however instead of raging around or in fact killing these humans whom he saw kokushibo decided that diplomacy was the key to the situation and it was because of Hiro's hanafuda earrings the dance and a scar on his forehead yes aside from reminding him of his brother kokushibo realized that these people were affiliated with yorichi one way or another and it was too good to be a coincidence as we all know since tanjiro is the kind of person who hears demons out he agrees to listen to kokushibo when he says that he wants to tell his story he explains his past how he became a demon and how he and yorichi eventually betrayed the Demon Slayer core however like the sneaky little demon he is he added a bit of a Twist to the entire thing to make it look like he was the good guy he explains that he ran away from yoriichi who eventually became the Demon King because they ended up fighting after kokushibo tried to convince him to stop all of this nonsense he also added a little spice saying that he realized his mistakes when in fact bro was just jealous he keeps on telling more lies saying that yorichi will eventually come for them because the hanafuda earrings that tanira wore symbolize the last remnants of the sun breathing users yuichi's arch nemesis now if you've watched the series you can easily notice that these are all just blatant lies but if you're tanero might be convinced and that's exactly what happened after an intense back and forth and a lot of talking kokushibo finally convinces tanjiro to become a demon to protect his family he also asked permission from tanjiro's siblings and mother and he promised that tanjiro would be safe during the transformation it was a success tanjiro has now become a full-blown demon and with kokushibo they train to control his new abilities it takes a couple of years for this to happen and during that time kokushibo was welcomed into the commo household and he became really close with tanjiro and nzuko to the point where where he somewhat got attached to both of them but good times don't always last forever because yorichi even after 2 years is still sending out search parties to try and catch kokoso before he completely messes up everything he's worked so hard for one of these search parties was attacked by a group of demon Slayers and there was only one Survivor left at the same time kokushibo and tanjiro were already out training because it was night time and it was the only time they could go outside suddenly tanjiro and kokushibo hear screams and they instantly Dash back home when they arrived they were met with a horrific scene the surviving demon in a bid to get some food and regenerate ransacked the kamado household and killed everyone inside when it saw both of them it tried to escape but kokushibo instantly killed it with one swing of his sword they were too late and tanjiro's entire family is dead tanjiro became full of grief and rage and surprisingly even kokushibo felt angry is kokushibo starting to change or are you just full of copium at this moment tanjiro swears to get Vengeance on his family and eradicate every single demon from existence especially Yori before they could bury the bodies however the Demon Slayer Squad that ambushed the search party arrived and when they saw the situation instantly thought that kokushibo and tanjiro were responsible before they can catch them however both successfully Escape but the one leading the Demon Slayer Squad guu feels like something is wrong and decides to investigate further as time passes by and tanjiro finally starts to move on in the hopes that he could finally get his Vengeance he and kokushibo train more eventually tanjiro Masters his demon form and even unlocks the sun breathing technique through kokushibo guidance his blood demon art is the same as Demon King tanjiro in the original timeline biokinesis where he can manipulate and change his body at will tanjiro can also maintain his Consciousness much better when in highly stressful situations meaning that he can use swords gracefully in battle with that in mind kokushibo decides that it's time that tanjiro gets a proper Nerin sword and to do this they go to the first location kokushibo had in mind the former Demon Slayer headquarters remember when I mentioned that kokushibo killed the oaka when he first became a demon yeah because of that incident the Demon Slayer core decided it would be a good idea to hide their headquarters in a more remote area and abandon the last one that came under attack as they travel towards the location kokushibo leads the way and reveals why it was abandoned essentially trusting tanjiro with his path they reach the ruins of the old headquarters and go through the rubble and abandoned buildings as they reach the Armory tanjiro finds an old sword and instantly takes it it was still sharp usable and most of all was made with Nerin but before they could even collect their thoughts guu and his Squad ambushed them these guys just seem to be really good at jumping people guu reveals that they have been tracking them for weeks on end because of this disturbance kokushibo gets annoyed and is ready to throw hands and essentially just murder the demon Slayers so they won't be a burden anymore luckily for them though tanjiro stopped kokushibo and convinced him to let him take on the demon Slayers because it'll be good practice both sides ready themselves and one Demon Slayer takes the first move in the blink of an eye he is instantly knocked out and as he approaches tanjiro they suffer the same fate they aren't dead though just unconscious it was such a one-sided fight that after a few minutes gu was the only one left standing seeing that guu was the most skillful of them all and probably the highest ranked tanjiro tried to talk to him he explains that both he and kokushibo are on their side and actually want to kill the Demon King gu thinks this is all a trick which I mean is fair and tries to attack tanjiro again with a lot of skill he instantly subdues guu pinning him to the ground tanjiro tries to talk to him again and seeing that he has no choice guu hears him out tanjiro requests that they be taken to the head of the Demon Slayer Corp and seeing that this was an awful decision because they could instantly be ambushed again gu you except he says that he'll be their guide but in exchange they have to spare the lives of his men since that was what tanjiro wanted from the start he accepted and they made a deal guu talks to his men and orders them to inform the oaka ahead of time as well as to bring every available hashira to the meeting site for security purposes when they reached the Demon Slayer HQ all of the hashiras waited for guu tanjiro and kokushibo at the gate and with them were hundreds of demon Slayers to prove that they actually mean no harm to the humans the oyakata kagaya ubuyashiki makes them take a test similar to the one nzuko had Sunami cut his arm to test both of their tastes for blood and let's just say that they passed with flying colors this is because both of them have already mastered control of their demonic urges because of this kagaya agrees to have a meeting with them in their meeting kokushibo and tanjiro reveal everything there is to know especially what kokushibo predicts is the Demon's true strength as well as yuichi's plan to eradicate the Demon Slayer Corp with this information the hashiras argue for a while but overruling everything kagaya agrees that they should work together especially since yorichi is a bigger threat compared to muan and so their preparation begins with their collaboration Now set in stone kokushibo trains and teaches the demon Slayers everything there is to know about demons including their Anatomy possible weaknesses and their new tactics since most new demons were former demon Slayers themselves they will be more organized and will likely have a proper strategic plan on the other side of the training grounds tanjiro spars with the hashira and the other demon Slayers he beats most of them in a one-on-one match and truly emphasizes that the demons that they will be facing will be strong deadly and smart as the demon Slayers hone their skills and prepare for the upcoming Final Battle Cami spots something in the tree line he dashes closer and realizes that it's a flying eye and it was secretly deployed by nakame to know their whereabouts he instantly reports this to kagaya and the other hashiras saying that the demons already know of their location with this sudden news kagaya announces to all demon Slayers no matter what the rank to go back to headquarters and help in fortifying their positions this includes setting up high walls obstacles and defenses that can slow down or kill the demons the Demon Slayer headquarters is ready and they are now waiting for the demon attack just imagine a heavily fortified Japanese castle with walls that were shaped like the letter U and that's what it looks like with everything set in stone everyone inside the headquarters is on high alert there are three walls set up that surround the castle one in the middle and one on each side with mountains at the back making it impossible for demons to enter there the tension is high when out of nowhere a Demon Slayer screams at the top of his lung lungs saying that he's seeing ice at the middle section of the battlefield everyone rushes to that part of the wall to see what it is and instantly sees Domo with what looks like dozens if not hundreds of demons behind them and they aren't only attacking from there to their right they see hang and gyoko with more demons yoko's fish monsters and hango already split into several clones lastly at the left wall we see yorichi himself with aaza and kyaku along with some lower moons and another couple hundred demons the demon Slayers ready themselves for the onslaught while the demons sharpen their teeth and to finally eradicate their ancient enemies once and for all Koko's eyes line up with yuichi and yuichi points his sword at kokushibo it was the signal to attack all of the Demons from every side start running towards the walls with the lower ranked ones going in first but they were caught off guard when the demon Slayers at top the walls replaced their swords with what looked to be muskets but wait you might be thinking guns and Demon Slayer impossible well little did you know that in the Taisha era guns had already arrived in Japan and these muskets were directly inspired by genus shotgun demon Slayers fire volley after volley mowing down a lot of the demons that came charging in the first wave but with a low rate of fire and long reload time some of the Demons eventually reach the walls and start climbing to counter this and hopefully slow them down the demon Slayers use good old-fashioned oil and drop it on the demons after that they ignite it creating an inferno around the castle unfortunately for them though this doesn't kill the demons but instead just slows them down as Burning Alive means that they have to focus on their regeneration it seems like the demon Slayers could successfully defend their head qus without a single demon stepping inside it but they were so wrong from the middle Doma launches an attack and freezes everything on that part of the wall material and Demon Slayers alike with another blow that looks to be a giant Glacier the Frozen middle section of the wall is destroyed giving the demons one hell of an opening to counter this breach guom and Cami possibly the Demon Slayer strongest Fighters with hundreds of demon Slayers are sent out to face the upper Moon 2 meanwhile at the right wall the demon Slayers are doing a lot better after the initial musket fire mow down the first wave guu shinobu and rengoku put their brains together and execute an amazing 1,000 IQ move they actually Sally out with three dozen demon Slayers and attack the confused and shocked demons getting rid of the stragglers and when Han tangu and guoko make a move they just Retreat back inside the walls it's a rinse and repeat process that causes a lot of casualties on the demon side at the left wall perhaps the most dangerous section of the battlefield the situation was deteriorating rapidly although the gunfire caught the demons off guard yuchi ordered kaiaku to take Take Out The Rifleman at top the walls with his thunderblood demon art killing or stunning most of them and leaving the entire left wall without any range defense what made it even more horrific was the fact that when kaiaku attacked the oil that was supposed to be dropped on the demons at the left wall combusted burning the fortification and giving akaza the chance to destroy the wall altogether creating a massive opening because of this KIRO and kokushibo rallied the most demon Slayers including four hashiras muo Tangen obanai and mitsuri they formed a line and prepared for the imminent assault as the smoke from the chaos cleared they saw that all the demons were charging them and in response kokushibo made an insane order to counter charge the two sides clashed across the entirety of the headquarters in a Fierce and bloody battle aaza was fighting against muichiro obai and mitsuri while tangan insisted on handling kyaku alone tanjiro and kokushibo faced yorichi while we all know the rest due to their exposure to tanero all the hashiras unlocked their Demon Slayer marks which gave them a massive boost and strength and overall physical stat as the battle raged on henu and guoko were easily defeated by the hashiras with guu losing an eye and rengoku a couple of fingers but that's not to say there were no casualties as half the demon Slayers there died in the process now that the right wall was cleared the hashiras ordered the low ranked demon Slayers to guard the section while they and a dozen or so others reinforced the other sections shinobu and guu went to the middle while rengoku proceeded to the left in the middle even though there were a bunch of hashiras akaza was just too strong and he really deserved to get the title of upper Moon they tried their best but it wasn't enough and they were being pushed back to win this situation shinobu thought of the inevitable she said goodbye to guu and told him to take care of Kano who was also in the battle she used everything she had to attack Doma eventually sacrificing herself in the process and poisoning him like in the original timeline this gave the others the opening they needed and successfully beheaded him the battle in the middle section resulted in shinobu's death and guom losing an arm with that out of the way the only section they had to take care of was at the left kyaku was already dead while akaza was being p pushed into a corner yorichi saw that his forces were losing so he escaped out of tanjiro and kokushibo sight utilizing the transparent world to Blitz every single Demon Slayer he saw in a Flash he killed obanai and tangan and was just about to kill tanjiro but kokushibo blocked the attack and used his body to save tanjiro sacrificing himself he didn't know why he did it but deep inside he thought it was because he grew fond of tanjiro and admitted that he resembled yorichi when they were still Brothers as he set his farewells yorii cut his head off kokushibo dies and tanjiro goes berserk mode having an evolution and turning into something even more demonic out of the demon Slayers present in the middle Cami was the only one to arrive on the left and he saw that they were losing that area even though he was pushed into a corner akaza still was able to kill mitsuri too in this desperate moment tanjiro tells everyone to stand back everyone heated his words and the rest of the demon Slayers on the right led by sanami focused on killing all the remaining demons while tanjiro focused on yoriichi once again the fight was intense and throughout all of it tanjiro almost lost his life a couple of times the entire battle lasted throughout the night and as if the gods were smiling upon them a miracle happened the sun rose up because the battle took too long and yorii was so consumed by rage and his Twisted ambition to kill the demon Slayers that he didn't even notice it every single demon was eradicated and Sami found his opening to finally end aaza KIRO and yorichi stopped fighting and looked at each other to be honest they kind of mirrored each other's lives and they were the same person with the same experiences born in different eras as the morning sun reached its peak tanero bid his farewells to yorichi and out of nowhere said that he was glad that his miserable life finally ended at the hands of one of his most trusted friends seeing sumiyoshi and tanjiro dead tanjiro looked back and saw that the surviving demon Slayers had gathered behind his back watching him with pride compassion and a sense of sadness he also bit his goodbyes thanking them for their sacrifice and help assuring them that the world was now safe but as he bathed in sunlight tanjiro and every single person at that moment noticed one thing he didn't burn if you enjoyed
