Incarnation and Reincarnation

Yoriichi walked subtly through the snow, he walked holding his katana he then heard footsteps, until then he saw Tanjiro, but not alone he heard footsteps, he smelled it and then felt a shiver through his body.

He turned around and saw in the distance, a big "Bear", that was running towards him, Yoriichi still kept his calm face, with his serene expression, so he put his hand on his scabbard, and walked calmly ignoring Tanjiro who had been walking until then. and stopped, until a smell flooded Tanjiro's Nostrils

"A bear? here?" .- he asked as he smelled the animal in the distance, as he turned, in the direction where Yoriichi was going.- "He's heading towards the Bear?!?! ."- Tanjiro worries strongly.-

Until the serene expression never left Yoriichi's face, he started to stop walking and then ran at high speed, he jumped up getting higher than the bear, he took out his katana, revealing a normal blade, with a flame design across the blade.

Yoriichi simply cut the Bear's neck, and then he got on his back and stabbed his sword, and went down making the cut bigger.

"Forgive me poor animal, but you were attacking my family, and then you died" .- thought Yoriichi as he looked with his serene expression, but with a pity look on him, as he looked until the Bear fell to the ground dead.

The Transparent World Vision, he could see through the creatures and see the world slower.

Yoriichi made a slashing motion in the air and the blood on his sword fell to the ground, Tanjiro who finally arrived he opened his mouth and closed it.

"Saiko Tanjiro."- He spoke as he spoke calmly and put the sword away, while he took the bear on his back and took it easily, today would have a meal... a different one.-

As he walked, Tangiru came over.

"Nii-san what's that?" he asked as he followed and looked at him.-

"A cut".- he said with a chibi face, as he carried the bear and walked faster, trying not to talk about it.-

But Tanjiro is a curious boy, he tried again.-

"B-But Nii-san, you were running at u-a very fast speed, and then you jumped too high and you killed him."- Tanjiro said.-

"I walked, jumped and did a simple cut."- Yoriichi said while keeping his solemn expression.-

Tanjiro would pout and try to get Yoriichi to talk, but the older boy he was someone of few words.

************************************

Yoriichi climbed the mountain, he talked as he got to the top, the snow was over the place, but he didn't care, as he got to the top he smiled feeling the wind, until then that smile became a spiteful smile, he didn't think who deserved this life.

How many lives he took, the more he will fulfill a promise a long time ago, he fights to become a good person, the more he killed so many, it happened so long ago… but what happened made him too strong.

Then, a person literally identical to him appears in front of him, wearing the same clothes, but a different sword.

Aquele era Yoriichi Tsugikuni.

Or rather, the spirit that has been haunting Ken for a long time.

"Again? ''- asked "Ken" while looking at Yoriichi.

"Until you can breathe properly, defeat me and then I see you use the 13th Form correctly."- Yoriichi said as he took out his nichirim revealing a crimson blade that shone like the sun.-

They both knew that the day this would end seemed close, they both knew that they were theoretically the same person in this life.

Both knew that Yoriichi Ken, and the Reincarnation of Yoriichi Tsukigani

"(Breath of the Sun: Fifth Form: Kasha)" .- Ken jumps behind Yoriichi and spins downwards in the air, striking him with a sword attack in a circular motion, as the flames go out, Ken knew about Yoriichi being the creator of Breath, and it would be almost impossible to defeat him, but.

Who said a copy couldn't outperform the original.

But Yoriichi already knew which move to make he just disappeared from Ken's sight, who didn't change his expression, so he turned around, Yoriichi simply appeared in front of Ken with his sword raised.

"(Sun's Breath: First Form: Enbu!) .- Yoriichi said when he breathed, he could kill all the Onis, there were none left.

Not even Muzan escaped, he may have run away, but he was left with scars and trauma for his eternal life forever.

The Crimson Sword started to glow, fire came out, a vertical cut from top to bottom, the 2 weapons clashed, as Ken turned his body, and made the blades clash, Ken's blade broke, but that was no problem because.

He was no ordinary person.

"Trace On!"

He really wanted to but use magic or magecraft, in that world he is likely to be burned, for Kami he is afraid of what might happen.

But now returning to the battle, Ken came back with the new blade, so he breathed the air into his lungs, and then began to brutally attack Yoriichi, who also didn't change his expression.

Both marks seemed to grow a little on his face, and then the sword fight went at a fast pace, not being seen by the common human eye.

The sparks fell, the place seemed to heat up 2 Sols fighting, the ice melted as the 2 used their swords, and then the wind cuts that came out of each by the force of the blow.

It seemed like everyone wanted victory, but Yoriichi didn't really want to, he wanted to see how a master like Ken evolves, and see if he didn't make the same mistakes he did.

Flames started to come out of both weapons, each making a colossal shock wave on the spot, both should probably be good but Ken specifically wants to be the best, he wants to be the best but he wasn't jealous.

He knew the History of his Incarnation.

The story of the greatest demon hunter, who was lost.

Yoriichi was born with the Hunter Mark equal to Ken, but he was born with all of her power, both the Transparent World and the Selfless State, along with the greatest speed, greatest strength, greatest stamina and endurance.

He with a simple movement and breath, made cuts in Muzan that left him traumatized.

But in the end Muzan was smarter and managed to escape.

but Ken won't make those mistakes why?

Simple, he had the same purpose that Yoriichi had, they were only born in this world to kill someone.

Muzan, that's why they were born, They were born to kill "He" but Ken had made a plan for "He" each had their weakness, but the most differentiated would not be Muzan, it would be someone within the parameters of the Upper Moons, something Ironic that he's a moon.

But each step with its time, he vowed to kill every demon in existence.

He will fulfill that promise to prevent deaths.

Ken returned to the real world, all those thoughts mere milliseconds in his head.

Ken then raised his left hand tracking another katana, then he started using the dual grip, and fighting.

Yoriichi now seemed to fight more defensively, while Ken used the 2 katanas then.

"(Breath of the Sun: Seventh Form: Youkatotsu!)". - Yoriichi said as he took his nichirin in a similar way to someone trying to pierce something with a spear with the tip of the katana.

the Curved Form like a whirlwind of fire coming out of the sword, but Ken already knew how to dodge it.

"(Breath of the Sun:Fourth Form: Gen'Nichi Kou)" .-Ken performed high speed spins and rotations, making afterimages of him, and with his increased speed thanks to the form, he made a turn to come up behind and then .

Ken felt a shiver in his body as Yoriichi disappeared from his sight.

Then Yoriichi appeared right in front of him, and then he just heard Yoriichi's calm, serene voice.

"(Sun's Breath: Thirteenth Form: Jū San no kata)" .- spoke before Yoriichi disappeared from Ken's sight, and then he saw the sun.

****************************************************** *****

Ken was sitting, while next to him was Yoriichi, well the 2 were perspectives and knew each other's lives.

Both are the same person.

But Ken followed his ideal of helping others by killing the bad guys.

Yoriichi gave up using the sword because he felt horrible for hurting other beings, until then he lost his wife and son and decided to fight so that no one felt the same.

And yet, Yoriichi saw the path that Ken had chosen and he saw what his end was, and Ken knew what Yoriichi's end was and his path and the tears that fell.

Dying standing up as a man, his death was a blessing but the being he faced was a curse, after all Yoriichi took the chances of victory in his coffin.

How they know about their lives.

Simple, both are memes, and Yoriichi is dead, but he still has things to do, even if only Ken can see him.

But they didn't care, and they both knew that after it was over, Yoriichi would disappear from Ken's sight, but he could never really disappear.

After all, both are the same sun.

"After I return to the world of the dead, could you do me a favor?".- Yoriichi said as he looked at the setting sun.

Ken just looked at Yoriichi, the slight difference in size but it won't change much in a few months or so.

"When we're done, I want you to find my brother, and please finish what I've started, free the darkness that eats away at my brother… he's turned into an Oni, Muzan has corrupted him, so free him from that darkness."- spoke while there was about 1 minute left for the sun to set.-

"Yes, but if he is his brother, then he is a Higher Moon plus which one?".- asked, Yoriichi fully told the Hierarchy of how the demons are, from the Lower to the Higher, and in the end the Demon King.

"He and the Upper Moon 1."- He said as the sun disappeared from view, it had already fully descended, and so Yoriichi was gone.-

Now Ken opened his eyes a little, so he shuddered a hunter alive 400 years ago? who could have trained all this time?

He must be a monster to the other demon hunters, because for him, mission given is mission long.

He then sighed, some habits never change, but he gave up on being a murderer, but if someone hurts the one he loves, he may die again, but he himself will make a point of making his own hell and taking him there.

But now, there was still some time left, he had to follow the legacy of his family, and do the Hinokami Kagura.

He sighed heavily, tiredness fighting his Incarnation, even though his skill was on another level, was strange.

Ken had more Skill than Yoriichi, he saw the greatest swordsman this world has ever seen, by their swords and replicated every move to become perfect and then improve them to become his own.

He's taken all the swords of a legend, but why then can he barely get past Yoriichi?

Simple Yoriichi knows all the moves that Ken tried since he was 5 years old, Yoriichi learned at a frightening speed then he learned and got better not to mention that Yoriichi is the strongest man in the entire history of this reality, now the strongest and Muzan, or better would be why?

Simple, Ken was here

So he took advantage of the night breeze and then he jumped the mountain and started down, with full speed until then enjoying this peace.

****************************************************** *******

It was time for the entire Kamado family to be together.

Black stakes were embedded in the snow-filled ground, so Yoriichi Ken calmly arrived in Hinokami's costumes.

He walked to the middle of the place, all his brothers sighed in inspiration, Tanjiro had a nostalgic smile.

Yoriichi then swung his leg through the dirt along with the snow, making a half circle, then he started to turn around.

Then he began to dance making a vertical cut, then a horizontal one, while memories flooded him of his past life.

Many things he did but the question came

Was he worthy?

He then made a movement with the sword he had in his hands, his whole body moved, with light movements.

Even so, the movements made his family not want to stop watching.

More Kie saw her 4 children less Tanjiro falling asleep.

"Tanjiro, help me carry your brothers, they are almost asleep and Yoriichi will stay until dawn."- Kie said as she looked at the second oldest.

"Yes Mom".- He said with a gentle and calm smile.

Kie carried Rokuta and Shigeru, while Tanjiro carried Hanako with him in a hug, and shook Takeo's hand, Nezuko then took Takeo's hand and then they took one last look at Yoriichi who continued to dance.

Everyone left the forest, while Yoriichi himself continued to dance.

Until he heard footsteps, even then he wouldn't stop, until dawn he wouldn't stop, he trained night and day, so that when the time came, Muzan would fall easily.

The footsteps seemed to get closer and even then he didn't stop, the smell was human, more unknown to Yoriichi.

Then he shook his body and then he cut the air again, and now the sword was twirling, he heard the footsteps get closer, and then he heard a breath.

He danced for just over 3 hours, and still didn't stop he simply had to comply not caring about his body or his stamina in the process, so the silence graduated only with the sounds of wind cuts, which Yoriichi made, or better when it ripped the air simply

So he turned his body

And after that he decided to speak.

"Who's there."- Yoriichi said as he continued to dance.-

"Ara?".- came the female voice with a surprised tone, Yoriichi almost fell, but turned and did a quick somersault preventing him from falling.

"I asked you who is there, if your intention was not to be revealed, train your instincts more."- Yoriichi said in a simple and serene way.

"Ara ara, I will listen to your advice, now why are you doing this?".- came the female voice.-

"A family ritual... passed down from generation to generation, we danced to celebrate Kami...to bring the good news, I'll be doing it until dawn.- he said in a simple and paused way.-

"Ara ara, the more you can get sick."- said the voice in a tone like a sermon.-

"Haven't you noticed? why isn't there snow on the ground where I step?".- he said while cutting the air with dance moves.-

The unknown girl seemed to fall silent, and then he entered the circle.

"It's hot here".- she said while for some reason he was sure she put both hands on her hips... call it intuition

"...."- For some reason Yoriichi didn't want to talk anymore.-

"What's your name?".- came the woman's question.-

"It's impolite to ask others' names when you don't introduce yourself first."- came Yoriichi's calm and calm reply.-

"Kocho Shinobu".- came the answer from now Shinobu.

"Kamado Ken Yoriichi."- was Yoriichi's reply

"So, Kamado-san, could you tell me if you saw something big…- she stopped to see the huge veil on Yoriichi's head, who until then had stopped, and now looking at Kocho, as she took the veil off her head. -

A demon was around, he realized that Kocho was a hunter, because she gave off a smell similar to her Master's nichirin, and also looking closer he saw that Kocho

She is a petite young woman with pale skin and large, compound eyes with no pupils, just a gradient purple haze, making her eyes appear insect-like. She has shoulder-length wavy hair that ranges from black to dark purple, usually combed at the back of her head in a flat 'yakai-maki' bun, secured with a white and purple butterfly ornament.

She has voluminous, ear-length curtain bangs, parted in the center that come down to frame the sides of her face, with two slightly thinner chin-length locks of hair in front of her ears below them.

Shinobu wears the standard Demon Slayer uniform with gold buttons, consisting of a straight-lined black jacket in shades of dark purple and matching colored tabi socks and hakama pants, tucked into Kyahan with white butterfly print fading into light turquoise and pink around it. of her legs, closed with white ribbons.

Over the uniform, she wears a white haori that has a butterfly wing pattern that fades into a light turquoise and then into pink on the sleeves and hem which are cuffed with a black and white dotted edge. She wears white zōri sandals with purple straps as footwear, with a blade hidden in one of the heels.

But Yoriichi's main thought was.

"She is beautiful…. and low".- He said, really admiring the beauty of the woman in front of him, and seeing that he is almost bigger than her by 30 cm.

"Well Kocho-san, could you keep talking, it won my attention, if I saw something big in.- he said as he cranked up all his feeling to the max, he had attention on something.-

Kocho on the other hand looked up and saw Yoriichi's face, she saw and admired it down to the last and main details.

Until then he looks to the side as if he sees something, he looked like Kanao like that, does he have a good vision like hers?

Then she saw the flame mark going down his forehead and below his eye.

on the one hand, she realized she was staring too much until she saw Yoriichi looking at her with a raised eyebrow.

She looked away, while Yoriichi did the same.

For a second, the red wire connected to both of her pinkies revealed itself and disappeared.

Yoriichi then tidied things up and then saw the weather inside the circle turning cold again, snow was falling as he circled, he then took his scabbard, and then he quickly tracked down another katana.

"Let's go".- He said as he went behind the tree and quickly changed his clothes, returning to his red haori, with his yellow kimono.

He simply put on his wooden sandals.

He turned to Shinobu, who was staring at him.

"I know where he is, let's go".- He said while Kocho was serious, even more with his smile on his face.

So the 2 set out to hunt.
