Yoriichi was running through various fields. He was running towards a house.
'Tamayo told me Muzan is hiding here.' Yoriichi thought.
He reached the wooden house but it was thrashed. It looked like a storm blew it over but Yoriichi knew what it was.
"Muzan..." Yoriichi uttered in fury.
'But why is this house destroyed? Who was Muzan fighting?' It unnerved Yoriichi that someone else is able to provoke Muzan into fighting.
He noticed the whips lying around the destroyed house. "Muzan's whips." Yoriichi inspected them.
He found a blood trail leading further out in the snow and the woods. "This blood...It's Muzan's. He was injured and retreating?" Yoriichi assumed.
He followed the blood trail and found a man. He was very muscular and had purple hair and what looked like to be a horn on his head????
He was surrounded by splinters from trees and he wss standing in an empty space.
Yoriichi cautiously approached him. "Oh? Who's this?" Kars turned around and saw Yoriichi.
'This man...he is built like...a god...I don't sense him to be a volcano like Muzan...I don't know what he is...' Yoriichi thought.
"What happened to Muzan?" Yoriichi asked.
"And I assume you must be Yoriichi?" Kars asked as he was surprised.
'He knows me? Did Muzan tell him about me?' Yoriichi thought.
"He showed me his scars that he got from you." Kars said gesturing to his chest and then the bloody area around him.
'He had scars?' Yoriichi was surprised.
"Before I ate him of course." Kars said as Yoriichi was surprised.
'He ate Muzan?! HE ATE MUZAN?!' Yoriichi was astonished.
Yoriichi unsheathed his blade and threw the sheath away.
Yoriichi entered the see through world and saw through Kars. 'He doesn't have extra organs like Muzan but there's blades in his forearm and he has a peculiar energy flowing through him' He thought.
"Oh so you're going to fight? Regardless I was going to kill you anyway." Kars said as he got his bone blades out.
'When a warrior throws away his sheath it means he doesn't expect himself to survive.' Kars thought.
'He is dangerous than Muzan. He might be the most dangerous thing on this planet. I need to kill him at all cost.' Yoriichi drew his blade.
"Well come on, show me what you can do, Yoriichi!" Kars exclaimed as Yoriichi dashed at him.
"Flame Dance!" Yorrichi used flame dance and sent a vertical swing.
Kars was surprised by his speed and and the fire sword so he immediately went to dodge. Kars successfully dodged the vertical swing.
But Flame Dance is a two combo move. Yoriichi sent another horizontal swing and this time Kars tried to parry it with his blade on his right hand.
But Yoriichi's horizontal swing cuts Kars's bone blade clean off. "What!?" Kars was surprised that his bone blade was destroyed in one go.
"Sunflower Thrust!" Yoriichi tried to thrust his sword as Kars.
Kars immediately backed away by backflipping as Yoriichi finished his move.
'I got him there but there is no doubt that he will be dodging my every blow after that. Maybe it was foolish to attack first.' Yoriichi thought.
Kars looked at his right hand "I should've known, only a hamon warrior could bring Muzan to the brink of death. Never thought it would be one with a blade." Kars cursed as he retracted his broken blade back into his hand to heal.
'Hamon warrior? A single one of these hamon warrior is capable of bringing Muzan to the brink of death, without a blade?' Yoriichi was surprised. He wants to meet one of these warriors and learn their ways.
"But this man...he is unbelievably fast.' Kars and Yoriichi thought as they were still standing observing eachother.
Both Kars and Yoriichi looked up the sky. 'Five hours till dawn' Kars and Yoriichi thought.
'Hamon doesn't really strain on the body but it does on the brain. Eventually even an elite like him will lose his breath even for a moment. It'll take...' Kars thought.
'While there is no one who can do Sun Breathing better than I, doesn't mean it doesn't strain on my body. I can continuously use it for...' Yoriichi thought.
'Half an hour.' Both Kars and Yoriichi thought.
Both Kars and Yoriichi dashed at eachother. Kars swung his left hand at him.
Yoriichi narrowly dodged by moving to the side and... Kars got close enough to him.
"Raging Sun!" Yoriichi sent two horizontal slashes at Kars. But Kars retraced his blade and front flipped over both of his fiery slashes that barely touched Kars.
'Now's my turn!' Kars assumed there was an opening for him and swung his left blade at his neck but...
'He's close enough' Yoriichi thought as he thought his next move finish him off.
"Burning Bones, Summer Sun!" Yoriichi changed his form faster than Kars anticipated. He sent out a circular slash that hits Kars's left hand.
'This move of his, it's a circular slash!' Kars figured out that it was a circular slash from the motion of the blade and his arms.
Kars left forearm got sliced clean off (Just like Joseph's) but he backed away before more harm could be done to him.
'He figured out that it was circular.' Yoriichi observed Kars clutching his arm.
'That bastard wanted me to attack so I would be in his range.' Kars gritted his teeth in fury until he realized something.
'He hasn't landed a hit on me, he hasn't healed his arm, his other blade is broken and yet why do I have this unnerving feeling?' Yoriichi thought in fear.
Kars stood up and got into a stance similar to a martial artist. Yoriichi used his X-ray vision (it is X-ray vision!) to see that Kars's blade in his right hand is halfway healed.
'He's on defensive. He is prepared for any attack.' Yoriichi thought as he prepared to attack.
Yoriichi dashed at Kars. "Solar Heat Haze" He unleashed a horizontal slash at Kars when he got close enough.
But Kars lunged back and dodged it while he swung his hand at him and Yoriichi side stepped making Kars miss.
"Sunflower Thrust" Yoriichi thrusted his fiery blade at Kars's neck.
Kars was frustrated and moved his body body 90 degree backwards like some limbo champion and dodged it.
Yoriichi's sword was near Kars's legs.
'Got you.' Yoriichi thought as he assumed Kars was stuck in that pose for half a second and got ready to swing his fiery blade.
Kars smirked and and moved his body even more backwards and did a backflip.
Kars landed and smirked and looked at Yoriichi. Suddenly Yoriichi's face started bleeding. There was a scar under his eye.
'If I haven't entered the see-through world...My face could've been cut in half.' Yoriichi thought as he looked at Kars who was surprised.
"What?" Kars was confused and looked at his right leg to see the blade on that leg was cut clean off as well.
Kars realized what happened.
Back when Kars backflipped, he got his blade on his right foot out so se can cut Yoriichi's head in half while his legs moved.
But due to Yoriichi's X-ray vision, he was able to realize what Kars was planning and quickly cut it with his sword before it could do further harm to him.
'But that was really close...' Yoriichi thought as he gripped his sword hard.
'This man has unnatural reflexes, skill and speed but after all...he is a swordsman and a swordsman could do only so much with a sword.' Kars thought as smirked that sends shivers down Yoriichi's spine.
Yoriichi dashed at Kars and..."Beneficent Radiance!" Yoriichi spiralled into the air and delivered a slash but Kars lunged back and dodged.
'That's number seven.' Kars thought as he dodged.
"Dragon Sun Halo Head Dance!" Yoriichi sent powerful and continuous sword attacks in the shape of a dragon.
Kars couldn't dodge them all so he has a few gashes. "Fire Wheel!" Yoriichi dished out another move the same instand he finished the last one.
Kars dodged by rolling away but there is a vertical scar on his head. Kars got up but Yoriichi was already behind him.
"Clear Blue Sky!" Yoriichi did the 360 degree attack while Kars just jumped up dodging it.
Kars landed as Yoriichi glared at him sweating. The snow around them had already melt from their fight. It wasn't so cold anymore.
Unknown to both of them, someone was watching them from the woods. It was Tamayo.
She came here to see Yoriichi kill Muzan but what she was seeing now was completely unexpected.
' I want to help you but I am nit strong but you're stronger than Muzan! You can do this, Yoriichi-kun!' Tamayo internally cheered.
"What's wrong? Am I too fast for you, Hamon sword warrior?" Kars taunted.
'Hamon sword warrior? The people he fought doesn't use swords?' Yoriichi briefly thought about what Kars said.
'I need to use my ultimate move. it won't give him a chance to move' Yoriichi got prepared to unleash his 13th form.
Kars felt the tension in the air getting heavier, hotter. It didn't feel like winter anymore. It felt as if they were in a desert.
'This must his ultimate move.' Kars got ready to take it on.
'He is going to use THAT it seems.' Tamayo recognised the form.
Yoriichi dashed at Kars once more but this time at his top speed that Kars didn't anticipate.
Yoriichi fiery blade was inches from Kars's neck but...'This is familiar.' Kars thought.
In just two seconds, Yoriichi finished his 13th form. Kars and Yoriichi were standing still waiting for the other to fall.
Kars was the first to kneel down on the ground followed by Yoriichi.
Kars tried to dodge the best as he could but he was covered in gashes and there's one on his neck and his right eye was slashed as well. Kars turned around and saw a bloody Yoriichi and smirked.
Yoriichi didn't come out unscathed. He was covered in wounds. He was shocked in disbelief at how Kars had dodged and inflicted damage on him.
'Yoriichi, No! I want to help him but...I don't know anything about that monster.' Tamayo gasped.
'That monster...he dodged...he dodged the most of it and he...he somehow bent his arm in a unnatural ways with his blade constantly retracting.' Yoriichi thought as he stared at Kars with blood on his right hand.
"Hmph, is that the best you can do? I guess doing everything would be your best." Kars taunted as he looked at him.
'Everything? He...he remembered my moves...he was able to memorize them and plan his way around my 13th form...I see.' Yoriichi thought in surprise. He was using his breathing to close his wounds.
Indeed, Kars planned his way around his moves. Kars was wounded because the speed caught him off guard and he let himself be as long as he could hit Yoriichi. Kars successfully made sure his neck wasn't cut off and constantly brought his blade in and out while bending his arm in unnatural ways to harm Yoriichi. After all, Kars know how to move his arms best.
Kars stood up again and flexed his muscles. The flexing closed up his wounds.
'Whatever that swordsman pulls out now will be useless. I know his every move, his top speed, his reflexes, his temperature and his height. Enough to end him' Kars got prepared to attack.
Tamayo and Yoriichi stared in astonishment.
'Even Muzan wasn't able to heal from my 13th form but he was!?' Yoriichi thought as he slowly tried to stand up.
Yoriichi then noticed something sticking to his hand. He brought it up to see the melted water from the snow staying on the surfsce of his hand, defying gravity.
'It's attracted to my hand?' Yoriichi thought. Then he noticed orange sparks.
'What is this energy?' Yoriichi thought in fascination.
He heard footsteps coming towards him at a fast pace. He figured Kars is dashing towards him.
Yoriichi braced turned around to see Kars blade on his right hand inches from his throat.
He immediately brought his blade up all fired up ready to cut Kars's blade but...from the corner of his eye he saw Kars's left hand also headed for him.
'He reattached his hand when I wasn't looking!' Yoriichi thought as he tried to dodge but then he realized something.
Kars wasn't targeting him, he was targeting his blade! One of Kars's blade was going to cut through his blade from it's blunt side.
'Shit!' Yoriichi cursed as he tried to move his blade away but Kars cut Yoriichi's blade clean off while Kars's other blade got cut off by Yoriichi's.
'Oh no, Yoriichi-kun! He can't do anything without his blade!' Tamayo thought.
Not even a second after Yoriichi's blade got cut, Kars kicks Yoriichi in the abdomen that sends him flying into a tree.
"Ack" Yoriichi grunted in pain as he still held the remaining of his blade. Few of his bones were broken.
"I won't be stopping until you're dead!" Kars exclaimed as he dashed at Yoriichi.
"Shit!" Yoriichi exclaimed as Kars swung and he ducked and tried to roll away.
A few of his wounds reopens from that roll.
Kars sends a punch to Yoriichi with his right hand since the blade on his right hand was sliced off.
Kars expected to punch through Yoriichi (Donut) with that but...to his surprise Yoriichi caught it with his left hand.
"What?" Kars was surprised that Yoriichi wasn't absorbed by him. He carefully observed to see orange sparks on Yoriichi's hand.
'Wait, THAT'S hamon! So what has he been fighting me all this time with?!' Kars wondered after recognizing real hamon.
'This power...it must be hamon. It is different yet...similar to my breathing technique. But here...I can feel the blood flow. My pain has been numbed...and I feel this energy flowing through me.' Yoriichi thought as he maintained his breathing.
"So that wasn't hamon, it seems but your hamon is just ametuer level. You won't end me with that!" Kars exclaimed as he clasped Yoriichi's left hand with his right hand.
And Kars swung his blade at Yoriichi's neck. Yoriichi doesn't have the same speed anymore and trying to move fast would reopen his wpunds.
'Breathe...just breathe. Feel the enerygy...Feel the flow of energy.' Yoriichi thought as Kars bone blade closed in on his neck.
It looked like Yoriichi was done for but...
"WHAT?!" Both Tamayo and Kars exclaimed in shock after seeing what Yoriichi did.
Yoriichi caught his bone blade...with his teeth!
'Arrghh...this power successfully moves through organic compounds and conducts through inorganic compounds.' Yoriichi was really impressed by this power.
Hamon was flowing through his teeth that caught the blade along with his saliva conducting hamon on the blade. It was indeed impressive but it wasn't going to hold down Kars for long.
Because Yoriichi was biting on Kars's bone blade and Kars was momentarily surprised, it was an opening for Yoriichi.
'Hinokami Kagura' Yoriichi used the basic sun breathing and cut Kars's left arm off again in a moment.
"No!" Kars gritted his teeth in anger. His left arm got cut again but Kars saw an opening and kicked Yoriichi's right hand which makes him lose his grip and drop his sword.
Yoriichi let go of Kars's right hand. Kars saw that the skin on his right hand's palm was bleeding.
"Damn you!" Kars cursed in fury but then he smirked.
'This hamon...it depends on my breathing and blood circulation. I can feel the power but I am not a professional at dispelling hamon so when I try to attack him...I might re-open my wounds due to the blood circulation and the power of the attack.' Yoriichi thought as he breathes. It seemed Yoriichi needed a new form tp beat Kars.
Kars then sent some blood flying at Yoriichi's eyes from his arm by squeezing his flesh.
Yoriichi was blinded from that. "I WIN! DIE!" Kars shouts as he sends a roundhouse kick at Yoriichi.
Unknown to Kars, Yoriichi still had his X-ray vision. He could see the flesh and bones from Kars's leg coming towards him.
Yoriichi grit his teeth and reeled back his fist and...
"Hamon Overdrive!" He punched Kars's feet. They stayed there like that. (Like the last kick The World threw and Star Platinum punching it)
All wounds begin to reopen from Yoriichi's body as Kars smirked but then...
Yellow-orange sparks start traveling through his leg as fiery hot cracks start to form and they spread to his body.
"WHAT?!" Kars was astonished. He screamed in agony as the fiery cracks melt through his body.
"I...Impossible!" Kars exclaimed in disbelief as the cracks near his head.
"I...I...AM KARS!" Kars screamed in agony as hamon ravaged his body and head.
Then his body melted so rapidly that it looked and felt like an explosion.
'Kars...that was your name...you...were the only one to push me this far and...give me the thrill of battle.' Yoriichi thought as he looked at the melting corpse.
Yoriichi touched his chest and brought out his brother's flute. "And I was able to keep you...safe" Yoriichi said as he collapsed onto the ground in exhaustion.
"Yoriichi-kun!" Tamayo comes running to his aid.
Yoriichi Wins!
65 years later...
Kokushibo and Akaza was walking on some path to a castle.
"So we'll be staying here for the day?" Akaza asked as Kokushibo nodded.
Akaza sighs. "I hate this...that we have to constantly find shelter and hide like cowards." Akaza said frustrated.
"This era is almost coming to an end. We're the last demons alive. After another century, we'll go back to eating humans." Kokushibo said.
"Yeah...eating humans..." Akaza said.
"You know, if you hate your life so much, you can go walk into the sunlight. It's pointless anyway." Kokushibo said as Akaza was shocked.
"Pointless? What's pointless?! I need to get stronger!" Akaza exclaimed.
"And then what!?" Kokushibo shouted as Akaza was surprised by his outburst.
"And then what? You will be able devour any human you like but then what? Eventually you'll be bored." Kokushibo explained.
"Look at me! I am leagues ahead of you and do you see a proud man?! A happy man!? A beautiful man!?" Kokushibo exclaimed.
Akaza looked at him surprised. "Life is pointless. Might as well walk into sunlight." Kokushibo said.
Indeed, Kokushibo does regret becoming a demon. He looks hideous, feels horrible.
'He has a point...what will I do...We don't have anyone to serve.' Akaza agreed.
'My family was killed by demon...and yet I became one of them. I rejected hummanity so I wouldn't die after 25 years to mark...that meant for a proud demon slayer...Why did I do all of this...To become like you...brother.' Kokushibo wanted to die more than ever.
"There's someone coming towards us." Akaza said as they both lo oked to see a man they thought died.
It was Yoriichi! He looked like he was in his fifties.
"Yoriichi...?" Kokushibo muttered confused.
'How is he alive?! We met 60 years ago! You must be 80 years old and yet you look like you're in your fifties and alive?!' Kokushibo thought astonished.
"Yoriichi? Wait, he's the one that killed Muzan?!" Akaza exclaimed recognizing Kokushibo's brother.
"This is heart wrenching...brother." Yoriichi said as they looked at him with tears in his eyes.
Kokushibo was surprised to emotions in his brother. For the first time he felt something swelling inside him.
"Akaza...you could run or die with me here." Kokushibo gave Akaza the options he had and started walking towards Yoriichi.
"Wait! Kokushibo-dono!" Akaza shouted as he watched them approach.
"How are you still alive? You should've been dead after you passed 25 years!" Kokushibo exclaimed as he walked closer.
"Brother...I..." Yoriichi tried to talk.
"Shut up!" Kokushibo shouted as they were surprised by his outburst.
"Why are you always the exception!? Why do the gods always favour you!? Why do you make me feel so...so Shit!?" Kokushibo exclaimed as he about to cry.
"You... abandoned me when we were children! You never showed me the slightest of emotion other than that smile like 'Everything's fine' and you are always breaking your limits! You..." Kokushibo struggled to find the words.
"You...are like this...bright shining light that...everyone looks upto while I just a NOBODY!" Kokushibo shouted.
"Nobody Yoriichi, I am a nobody! I accomplished nothing while you accomplished one thing after another! Why can't I...I...be like you?" Kokushibo was in tears.
"It's... all I've ever wanted." Kokushibo kneeled down while he was crying. Akaza and Yoriichi was shocked. It seems there is humanity even in the hideous of demons.
"You probably don't even remember my name...did ypu even come to check if I was alive?" Kokushibo asked looking at him.
"I...I have been looking for you..." Yoriichi said as he brought his flute out from his komono. Kokushibo was surprised that Yoriichi still kept the flute.
"Please...stop..." Kokushibo said as tears flowed down from eyes.
"Please...just end...my misery...end my hideous life." Kokushibo pleaded as he got up.
"Or I'll end yours!" Kokushibo exclaimed as he brought his blade out.
"Brother...I accomplished nothing...I failed at being a brother, I made my brother hate me, I couldn't kill Muzan an-" Yoriichi was interrupted.
"Say that again." Akaza said as Kokushibo stared at Yoriichi in shock.
"Yes...I didn't kill Muzan...Someone else killed him" Yoriichi said as they looked at him in shock.
"Who?" Kokushibo asked as Akaza was equally curious.
"A warrior of hamon. They used a far superior breathing technique than the one we use. Muzan was disposed of quite easily." Yoriichi lied. He didn't want to make his brother feel more inferior.
"Warrior of hamon..." Kokushibo mused.
"Never heard of them..." Akaza said worried.
"But as I was saying, brother...I am sorry for...all the pain I've caused you." Yoriichi apologised.
"Will you please forgive me?" Yoriichi asked looking at him.
"And what will that do? Will that bring me back? The hide-" Kokushibo was interrupted.
"Yes, actually." Yoriichi answered.
"What?" Akaza and Kokushibo said at the same time. They can be humans again?
"Tamayo...she made a potion that can turn a demon back to a human. It is proven that it works." Yoriichi explained.
"I...Impossible..." Kokushibo said in disbelief. He wasn't going to be hideous anymore?
"Even if you don't forgive me...I'll still turn you back into a human..." Yoriichi said as he thought about.
"You're not thinki-" Akaza was interrupted.
"I won't forgive you but I'll take up on your offer." Kokushibo instantly agreed.
Yoriichi smiled in joy. "Then I'll take up on your offer as well." Akaza agreed.
"Very well," Yoriichi agreed.
But then all of sudden an arrow hits Yoriichi in the liver.
"Ack!" Yoriichi was hurt as they were surprised.
"Yoriichi!" Kokushibo exclaimed as they noticed a chariot of zombie horses run at them. A shadowy figure was on it.
(Who's that pokemon?)
The shadowy figure threw away his crossbow and jumped up into the air.
"Wamuu!" Wamuu exclaimed as he landed.
(It's Wamuu!...No seriously, why does Wamuu say Wamuu? He does it in the game and the anime as well)
"I shall have my revenge on your for killing Master Kars!" Wamuu declared as he glared at them.
Kokushibo stood by Yoriichi to protect him while Akaza stood by them.
Next up: Kokushibo Akaza vs Wamuu
That was a lot. Thanks for all your reviews and sorry for any spelling mistakes.
And yeah...Yoriichi suddenly learning hamon might sound bogus but think about it.
Yoriichi invented the breathing techniques the slayers use. He is the best at it.
No one has been able to scratch him when he learned his way with the sun and blade.
He is lucky...well his body is. The gods have always favoured him like Kokushibo said.
Yoriichi is the one who will go beyons expectations and limits. He is the special one.
So with that much luck and similarity between his breathing techniques and hamon...he might just be able to unlick hamon and use it.
Joseph Joestar was special enough to use it effectively for the (allegedly) first time to shut down someone's brain and Yoriichi is just as special...that and once Yoriichi grasps how it works he'll use his lungs properly because he's a veteran-no an elite at breathing.
And don't underestimae the amount of hamon the injured dudes have. Baron Zeppeli was half a man when he gave Jonathan his hamon that allowed Jonathan to break iron.
And another thing is that the key to defeat the pillarmen is to surprise them. Like think about how Joseph beat them with tactics they weren't expecting.
So Kars didn't make the cut
.
.
.
.
On another note.Yoriichi and Kokushibo are like the Jonathan Joestar and Dio of Demon Slayer.
Like Jojo and Yoriichi were kind people. Their actions are what started the adventure.
Like both Dio and Kokushibo rejected hummanity but they felt love for their brother when they died.
.
.
.
And Tamayo could've least told Tanjiro about Yoriichi.
