Shun firmly threw a mental shield at the five Demons surrounding him. Then he drew his Nichirin Sword in his hand and spoke softly:
"This will be a good choice to test my swordsmanship against the deaths of four Upper Moons."
Shun's words were very arrogant.
Even the remaining Demons felt ashamed.
"What? You're so arrogant when you're about to die. What a waste of your handsome face." Daki said with disgust, losing her patience.
"You all need to be careful. He is capable of killing Doma and Akaza. It seems he is indeed a worthy opponent."
Kakushibo looked at Shun while drawing his sword with fighting spirit in his eyes.
Seeing Kakushibo draw his sword, Daki, who was like a child, also covered her mouth.
But only Gyokko, whose mentality was paranoid, did not take Shun seriously.
He was a Demon whose body was connected to a pot, his entire body was white, with yellow eyes, green lips, and purple fins on his head. His mouth was where his eyes were, his eyes were on his forehead and mouth, and several small arms grew from his head and other parts of his body.
He was cruel and arrogant, very talkative, and liked to mock others.
Therefore, while the others were careful in drawing their strings, he was very confident.
"No matter how strong you are, you cannot compare to us. Muzan-sama is very cautious. The four Upper Moons attack at the same time..."
"It won't be long before this guy's companions might hold his body and cry. That's what Demon Slayers have been doing all this time!"
"Hahahahaha..."
Gyokko smiled happily.
*WHOOSH*
*Pu-chi*
Suddenly, a dazzling light appeared, and the rest of his words were suddenly caught in his throat, his eyes widening.
Some looked on in horror as a line of blood appeared on Gyokko's neck, and then the line of blood grew larger. Finally, his entire head fell to the ground.
After that, Gyokko's eyes bulged in disbelief. He had a mouth, and even before he could speak, he was turned into black smoke by the energy of the sun and vanished from the world.
Upper Moon Five Gyokko died unexpectedly and fragily!
What actually happened just now?
It should be noted that Gyokko's body was stronger and harder than diamond!
At this moment, Daki and Hantengu suddenly became fearful.
"A group of minions, are they worthy of killing me?"
A faint voice sounded again, and the young man stared at them with cold eyes.
This time, all the Demons were shocked.
Although Daki and Hantengu were both Upper Moon Demons, this scene was quite frightening, and Daki almost screamed at Hantengu.
It was Upper Moon Five!
No matter how much Daki hated him, Gyokko was ugly and disgusting to a man obsessed with pots all day, but he was still a demon of the same level as her.
For the Twelve Kizuki, apart from Kakushibo, the difference between the remaining Upper Moons was not so clear.
But Gyokko, who was nearly as strong as her, was suddenly crushed to death without any warning, like an ant on the roadside!
The atmosphere suddenly became very frightening.
For a long time, Hantengu even broke out in a cold sweat on his face and unconsciously took a few steps back.
Nakime, who was on top of a tall building, stopped playing the biwa and trembled uncontrollably.
Now in this situation, her heart was swallowed by fear, and her face changed wildly. Her original arrogance had disappeared, her teeth were chattering, and her beautiful eyes stared at Shun in horror.
Because she felt the meaning of the sun on another person!
At that moment, she felt as if she was truly seeing the bright sun passing by.
"What is that?" The frightened Daki was already crying.
No one answered this question.
The atmosphere that was once intense now became an endless terrifying silence.
Especially the First Upper Moon, Kakushibo, whose expression was very strange at this moment.
He looked scared, angry, and at the same time envious and jealous. It was hard to imagine that Kakushibo, who was always as calm as the cold moonlight, would have such complex emotions.
The reason was very simple. At this moment, he saw in Shun a figure very similar to his brother Tsukiguni Yoriichi.
Moreover, the way Shun held the Nichirin Sword slowly made Kakushibo incessantly remember the fear of being nearly killed by Yoriichi, who was dying of old age.
"Sun Breathing!"
He ignored Daki's voice and finally confirmed the truth of the sword after a while. Kakushibo's emotions became more intense.
"You practice Sun Breathing!"
No one in this world knew Sun Breathing, but they would never forget it was Kakushibo and Muzan!
To surpass his brother, Kakushibo even chose to leave his family, wife, and children, becoming a Demon Slayer like Yoriichi and learning the Breathing Techniques.
However, while studying Sun Breathing, because he could not withstand the power of the sun, Kakushibo, also known as Tsukiguni Michikatsu, had to create an inferior version of Sun Breathing, the Moon Breathing.
Just like "no matter how bright the moon is, how can it compete with the sun?"
Because he always lost to his younger brother, who was a genius, out of jealousy towards Yoriichi and his desire for immortality, Michikatsu betrayed the Demon Slayer Corps in every way and joined Muzan, becoming the First Upper Moon, Kakushibo.
The existence of Sun Breathing seemed to remind him that he was not as good as Yoriichi!
Kakushibo never expected that after hundreds of years, he would see a Sun Breathing user again, especially since his aura was so similar to Yoriichi.
'Is this his successor?'
"Finally! Finally, I can fight you again?"
Kakushibo roared, seeing Shun tightly holding the Nichirin Sword in his hand, his fighting spirit boiling.
Yoriichi's death gave him a defeat that he would never be able to win back in his lifetime, making Kakushibo realize that he would never have a chance to defeat Yoriichi. Since that moment, he vowed never to lose to anyone other than Yoriichi.
Kakushibo admitted that he originally chose this evil intent to defeat Yoriichi, but Yoriichi's death meant he would never have a chance to surpass Yoriichi.
Then, he helped Muzan kill all the swordsmen who understood Sun Breathing.
However, now a new heir of Sun Breathing has appeared, just like the person replacing Yoriichi once again appeared before him.
Kakushibo deeply felt the presence of fate.
Perhaps he had become so ugly, so dirty and had honed his swordsmanship for hundreds of years in the world just for this moment.
Kill the heir of Sun Breathing!
Almost without hesitation, Kakushibo transformed into a Demon. His face became very fierce, countless swords appeared on his body, and the sword in his hand also transformed into a longer sword with a main sword.
"Boy who inherits Sun Breathing, state your name!!!"
Kakushibo roared angrily, and the terrifying sword energy spread in all directions, even splitting the floor around him, making Daki have to retreat in fear.
"Takema Shun."
Shun stopped not far away, calmly staring at the ferocious Demon in front of him.
"I inherit the technique of Sun Breathing from senior Yoriichi, and tonight I can help him understand the grudge between siblings."
"Tsukiguni Michikatsu, draw your sword."
As soon as the voice fell, Kakushibo unleashed his strongest technique without hesitation.
"Moon Breathing Sixteenth Form: Moonbow, Half Moon!"
Several giant swords of wind fell from the sky accompanied by countless full moon swords falling at the same time.
The surging sword energy condensed into a thin line at this moment. Kakushibo's attack produced hazy sword light in the air, like fog and rain, and slashed towards Shun from an incredible angle.
His sword swung freely, like a deer hanging its antlers. It was like a master swordsman of unparalleled skill.
*SWOOSH* *SWOOSH* *SWOOSH*
Countless swords of wind exploded in the thin air, with a sound that shook.
At this moment, the entire ground undulated with waves of air and countless sword lights, and their explosions were chaotic. Even hard stones exploded, and cracks burst from the ground.
"Your swordsmanship is good, but unfortunately, for me right now, there is no one in this world who can hurt me."
Shun's face was indifferent.
Kakushibo was very strong. Among the Twelve Kizuki, he always ranked first in Upper Moons.
Even Doma would surely be hacked to death when facing Kakushibo.
Shun had used Tsukiyomi nearly a hundred times, fighting with Demons day and night, just to train this Sun Breathing.
When Shun defeated Hashira with his swordsmanship, the Demon Slayer had no one who could match his swordsmanship.
After experiencing the battle with Akaza, using Sun Breathing, Shun had stepped into the Transparent World.
"Too weak..."
Shun shook his head.
After that, the sun appeared above the world.
The bright sun shone in the sky like the sunrise over the sea, illuminating everything.
Soon, a devastating explosion was heard!
*BOOOMMMM—*
Everything turned to ash!
Facing a realm he could never reach, Kakushibo sighed.
"I just wanted to be you, Yoriichi, why are you getting further away?"
"In the end, I didn't win anyone."
"Why was I born in this world? To make you glorious? So sad...!"
Kakushibo's entire body turned into pieces and turned into black smoke under the influence of the sun's energy and vanished from this world.
Among the tattered clothes, only two broken flutes given by Yoriichi to his brother four hundred years ago fell to the ground.
The First Upper Moon Kakushibo died!
After killing Kakushibo, Shun seemed to have crushed an insect to death. He rolled up his sleeves and calmly turned to look at Upper Moon Six.
As the eyes of both parties met, Daki was so frightened that she cried.
"Onii-chan—! Help me!"
A large wound suddenly appeared on her back, and then a lump of flesh and blood flew out and immediately transformed into a humanoid monster.
His hair was dark green, and his body color was light gray. The upper body was naked, the lower body wore blue pants, and his arms were wrapped in red and black ribbons.
There was no doubt that this was the real Upper Moon Six, Gyutaro.
"You are the one who bullied my little sister until she cried!!!"
Gyutaro holding two bloody scythes, roared, and when he saw Shun's face change, he became rough and twisted.
"You—!"
Gyutaro roared angrily. He stared at Shun's face, especially when seeing the other party so handsome, he felt jealousy and anger surging in his heart.
"Very good, with a tall figure, handsome face, white skin... Very good! Very good!"
An evil smile appeared on his ugly face. Gyutaro scratched his face with his fingers and stared at him.
"If your face is ruined, you will be very ugly!"
As the voice came, Gyutaro rushed towards Shun. This time he directly used his strongest technique.
"Blood Demon Art: Rotating Circular Slashes: Flying Blood Sickles!"
The blood slashes swirled like a whirlwind entangled in his hands. At this moment, Gyutaro's arm seemed to be cut at the highest speed, causing choking force and creating a strong wind flow.
Even a carefully crafted iron tool like the Nichirin Sword would turn into pieces if cut hard.
Shun recognized his opponent's technique. In the original work, Gyutaro unleashed this Blood Demon Art before he died, almost destroying the entire Yoshiwara street.
In terms of pure destructive power, it surpassed Akaza's attack.
Under the hopeful gaze of Gyokko, Nakime, and Daki.
Gyutaro screamed. The blood in his body exploded, and even the clothes on his body seemed to be blown by the wind and fluttered.
A small blood whirlwind appeared in the air.
This Blood Demon Art was like a miniature storm, even capable of causing wind changes, when run at high speed, the scythe swords inside it vibrated faintly, like a cutting machine. This attack alone was enough to penetrate armored vehicles.
*WHOOSH*
This attack split the air and decapitated Shun in mid-air!
"So, you have no memory at all while in your sister's body, right?"
Facing Gyutaro, Shun's expression softened slightly.
The frightened and crying Daki looked at her brother's figure and wanted to remind him.
Unfortunately, it was too late.
Shun tightly gripped the Nichirin Sword in his hand.
*CLANG*
The Nichirin Sword was drawn, and with a wave from Shun, the sword light containing the energy of the sun countered the trend. The momentum of this slash was extraordinary, and as the sword emerged, the entire wind froze as if still.
The red sword light transformed into an unreachable light, passing through the high-speed rotating Blood Demon Art, the bloody scythes, and Gyutaro's body, splitting him in two.
Daki watched this scene in a daze, the shadow of death almost making her faint, and she helplessly stared at her brother who had been cut in two.
"Think of something... If this continues, we will all die!!!"
Gyutaro tried to smile: "Sorry, Daki, Onii-chan... there's nothing we can do this time..."
"No... nothing we can do?"
Daki's eyes widened, and she made a fuss like a child.
"Why can't we do it! Why! Why do we have to die!"
"Damn it! It's all your fault, you useless bastard, you're so ugly, you only know how to sleep every day!"
Gyutaro shouted angrily: "The other party is clearly too strong, damn... Why didn't you tell me anything about such a strong enemy?"
"Damn! Ugly!"
"Waste..."
The two siblings suddenly began to argue.
"How could an ugly man like you be my brother! We shouldn't have blood relations! You're a loser! You clearly only know how to fight, if you lose, you're worthless!"
"Are you kidding? You would have died a long time ago without me! Do you know how many times I've saved you? You would have been dead a long time ago without me!"
Gyutaro kept shouting: "My life would be so different without you! It would be so fun without you! Why do you always have to clean up your mess? If someone like you wasn't born—"
However, he did not finish his last words, and the sun's energy turned him to ash.
"Onii-chan... Onii-chan... don't go... Onii-chan..."
Seeing this scene, Daki immediately knelt helplessly and cried.
"Daki..."
The young man's gentle voice sounded, and he did not know when the other party had been by his side.
Shun placed his palm on her head and gently stroked her beautiful white hair.
"Go, your big brother is still waiting for you, remember... even if it's hell, you must get along."
The next moment, the red sword light ignited.
Upper Moon Six, Daki and Gyutaro vanished like blue smoke.
At that moment, vaguely Shun saw a girl with white hair named Ume who playfully jumped onto her brother. She smiled happily and beautifully, clinging to her brother's back as if she had the whole world.
Gyutaro seemed to mumble something impatiently, but still hugged her tightly on his back.
The brother and sister embraced each other and disappeared step by step into hell.
