People in Demon Slayer: The Journey That Began with Demon Slayer

"Master Wuhan!"

Doma, Hantengu, and Inatama Kaigaku were terrified, never expecting that even under their combined attack, Tsugikuni Iwakatsu would still be able to break through their defenses.

Enraged, Kibu Y Muzan unleashed a wide-area shockwave, blasting Tsugikuni Iwakatsu away.

Feeling the wound on his chest, Kibuy Muzan, who had initially been furious, suddenly grinned maliciously.

"I see, Kokushibo. Although I don't know why you suddenly mastered the Breath of the Sun, you are not that man after all! Compared to his flames, your flames are far too weak!"

Kibu Muzan, who once fought against Yoriichi Tsugikuni, was slashed on the shoulder. The flames were like a bone-deep infection, and the wound could not regenerate. Even if the flesh covered by the flames was dug out and healed, the wound would never disappear.

While the wound inflicted by Jikoku Iwakatsu had the same effect, its power and strength were completely incomparable.

Although the cut was incredibly painful, it didn't have that insidious, lingering pain, and it was able to slowly regenerate.

Kibuy Muzan looked contemptuously at the panting Kokushibo: "I guess you won't be able to use your Sun Breathing for much longer. While you're using Sun Breathing, it's also eroding you."

Kibuy's guess was correct. Originally, the burning speed and recovery speed of the flames could be balanced, but when Kokushibo used the breathing technique sword form, the flames burned more intensely, and this balance was broken.

If the sword form of Sun Breathing is used continuously, Kokushibo Tsugikuni might be reduced to ashes midway through the battle.

As time goes by, Kokushiro's fighting strength will decrease.

——

Yosuke, who had just returned to the Butterfly Mansion from the ruins of Ubuyashiki, was about to calm down when he saw a figure appear in the moonlight.

Looking at the familiar figure, Yosuke tentatively asked, "Yoriichi?"

Yoriichi Tsugikuni looked at Yosuke with a sorrowful expression and pleaded, "Yosuke, there is something I would like to ask for your help with."

Yosuke asked in confusion, "What?"

"My brother is fighting a difficult battle with Muzan Kibutsuji on Sabetsu Island. I hope you can help him; this is my last request..."

Chapter 106 The Will to Slay the Evil Spirits of the World

The battle on Sabetsu Island continues.

Doma, Hantengu, and Inatama Kaigaku are holding back Tsugikuni Iwakatsu, while Kibuy Muzan is regenerating the brain that was destroyed by Tsugikuni Iwakatsu.

Although Kokushiro Tsugikuni's Sun Breathing cannot compare to Yoriichi Tsugikuni's, the flames of Sun Breathing are still able to suppress Muzan Kibutsuji's regenerative abilities, and it will take some time for him to fully heal and recover.

Meanwhile, Kokushiro was gradually losing his strength. He was almost exhausted after only using four Sun Breathing sword techniques.

At this moment, Sun Breathing is a double-edged sword for Kokushibo Tsugikuni. Even if Kokushibo Tsugikuni switches to Moon Breathing now, the sword form he uses will be imbued with the flames of Sun Breathing, because this is not Kokushibo Tsugikuni's own power and he cannot completely control it at will.

Doma covered half of his face with his fan and said sarcastically, "It seems I'm about to become one of the Upper Moon Ones, Mr. Kokushibo. I really have to thank you."

Inatama Kaigaku, on the other hand, had a greedy look on his face. If the order of the Upper Moons changed again, and he, who was now Upper Moon Five, advanced to Upper Moon Four, then he would be able to obtain more blood and become stronger.

Caught between a rock and a hard place, Kokushiro Iwakatsu had no choice but to fight a desperate battle.

"Breathing of Thunder? Sixth Form: Lightning Strike!"

Eager to achieve quick results, Inatama Kaigaku launched the first attack, unleashing countless lightning-like slashes centered on himself, and charging towards Tsugikuni Iwakatsu.

"Sun Breathing? Ninth Form? Radiant Grace!"

After the blazing flames on Kuniwa Katsu's crimson blade, as hot as the sun, incinerated all of Inatama Kaigaku's lightning, he unleashed a downward spiral slash at the charging Inatama Kaigaku.

Inatama Kaigaku's right hand was severed in an instant, and flames continued to burn at the cut of the severed arm.

Inatama Kaigaku stared in horror at his severed arm, for he discovered that the flames could not be extinguished and were still spreading towards him.

Half-Heaven Dog reminded him, "Hurry up and cut off the flesh covered in flames!"

Once he came to his senses, Inatama Kaigaku hurriedly used his sword to cut away the flesh covered in flames, but his arm still could not regenerate.

Having lost his sword-wielding arm, Inatama Kaigaku was almost unable to fight. Seeing this, Doma and Hantengu dared not let Tsugikuni Kokukatsu's crimson sword touch them and chose to attack from a distance.

"Blood Demon Art? The Frosty White Princess!"

Doma created two giant ice lotuses in the form of young girls, and Hakuhime blew out a wide range of freezing air from her mouth, which spread towards the location of Tsugikuni Iwakatsu.

"Blood Demon Art? Wood Dragon Gale!"

Hantengu's clone, Zōhaten, summoned a wooden dragon that spewed out a strong wind from its mouth. Combined with Dōma's Blood Demon Art, the freezing air was quickly pushed toward Tsugikuni Iwakatsu.

"Sun Breathing? Five Forms? Yang Hua Sudden? Violent Change!"

This is a sword shape created temporarily by Jikoku Iwakatsu, imitating the Moon Breathing? Fourteenth Form? Fierce Change? Tenman Slender Moon.

It can generate a large number of burning crescent blades, and as it charges forward, it creates a powerful fire tornado.

When Kuniwa Katsu's fiery tornado collided with Doma's freezing air, the extreme temperature difference between the two caused a series of explosions.

Moments later, the fiery tornado completely eroded the freezing air, and then Kokuichi Kokushi's thrust came.

Hantengu's strongest clone, Zōhaten, was instantly split in two by Tsugikuni Iwakatsu.

Doma's pair of fans were cut off, and a very deep wound appeared on his chest.

The three Upper Moons who arrived instantly lost their fighting ability.

Kokushiro was also in bad shape. His body could no longer withstand the burning flames from the constant use of the sword form of Sun Breathing, and his left arm was beginning to char from the flames.

Having opened the Transparent World, Kokushibo understood his physical condition. He knew that if he used Sun Breathing again, he would completely lose his fighting ability. Therefore, he could not waste his limited fighting power on Doma and the other two.

However, Muzan Kibutsuji, who had been watching the battle from the sidelines, had successfully regenerated his brain, which had been destroyed by Kokushibo.

Even though Muzan Kibutsuji lost one brain, his strength wasn't weakened much. However, he didn't want to experience being driven to the brink of despair again, so even though Kokushibo's Sun Breathing was inferior to Yoriichi's, he was unwilling to take the risk.

For Muzan Kibutsuji, the Twelve Demon Moons are merely tools that can be discarded at any time; their ability to utilize them is an honor.

The sword held by Kokushiro Iwakatsu lost its crimson blade form due to insufficient grip strength, and the flames on his body also weakened considerably.

Kibuy Muzan sarcastically said, "Although I don't know why you can use the Breath of the Sun, it seems that your Breath of the Sun can only be performed through external force, right?"

Yoriichi Tsugikuni is already dead, and you are about to die too. Now only that brat named Tanjiro Kamado knows the Breath of the Sun. As long as I kill him, the lineage of the Breath of the Sun will be completely severed. Who can stop me then?

The Demon Slayer Corps and Yosuke Ubuyashiki are no match for me now. Yosuke Ubuyashiki has always wanted to take me down with him, but I won't give him that chance. Once I become the ultimate being, I will settle accounts with them one by one. As my former right-hand man, I've been merciful to you. Kokushibo, they will all go to hell to join you."

Tanjiro Kamado, Kokushibo, had heard of the name but had never met him.

Upon hearing Muzan Kibutsuji say that Tanjiro Kamado had inherited the Breath of the Sun, Kokushiro Tsugikuni's heart calmed down.

Now, Kokushiro Tsugikuni had only one thought in his mind: "As long as the Breath of the Sun doesn't stop... Although we've never met, I believe that this child chosen by Yoriichi will definitely inherit Yoriichi's will and realize the vision that Yoriichi hoped for..."

Katsumi Tsugikuni gripped the blade tightly in his right hand and looked resolutely at Muzan Kibutsuji: "The Breath of the Sun will never cease, for it is not merely a breathing technique, but a spirit, a will to annihilate the evil spirits of the world!"

"Breath of the Sun? Twelfth Form? Flame Dance!"

Despite his battered and broken body, Kokushiro Kujo, with unwavering determination, unleashed two arc-shaped slashes wreathed in flames at Muzan Kibutsuji.

Despite his unwavering will, Kokushiro Tsugikuni was already exhausted, and the Sun Breathing sword form he managed to use was extremely weak in both power and speed.

Kibuyaku Muzan's hands transformed into whips, easily piercing through Kokushiro Tsugikuni's body and disrupting the sword form of his breathing technique.

Jiguo Yansheng collapsed to the ground, the flames on his body extinguished, and his body began to carbonize. It wouldn't be long before Jiguo Yansheng died completely.

Just as Kibu Muzan was about to kill Tsugikuni Iwakatsu completely, he suddenly sensed an aura that was the same as his, rapidly approaching the area.

Kibuyaku Muzan looked at Tsugikuni Iwakatsu, whose hands and feet were completely carbonized, and a disdainful smile appeared on his lips: "Ubuyashiki Yosuke, you're too late this time. When you arrived, there was only a pile of charred remains waiting for you."

A wooden door appeared in front of Muzan Kibutsuji, and Doma, Hantengu, Inatama Kaigaku, and the trapped priests disappeared on Sabetsu Island.

Chapter 107 Treatment

Yosuke is rushing to Sabetsu Island as fast as he can.

Yosuke had a moment of doubt when Yoriichi Tsugikuni suddenly appeared, wondering if it was Kibuy Muzan's unique trick to deceive him, wanting to lure him to Sabetsu Island and then ambush him.

However, this sliver of doubt was immediately extinguished. Kibuyaku Muzan, who had not yet overcome the power of sunlight, would never attack him. He knew that neither of them could kill the other unless one of them recklessly held the other down and exposed themselves to the sun together.

The most important point is the figure of Yoriichi Tsugikuni that appeared. If everything else can be faked, then the aura on his body is definitely not fake.

Pure, simple, calm, and gentle—that's how Yosuke views Yoriichi Tsugikuni's personality.

Regarding the soul, Yosuke has more than once doubted that the souls of humans in this world do not perish after death, because Yosuke has seen phantoms of people who were important to him in the past many times.

For example, Yosuke's parents, Kaori.

If what Yoriichi Tsugikuni said is true, then Yosuke can be certain that souls with strong obsessions did not reincarnate, but instead remain as souls, accompanying the people most important to them.

When Yosuke arrived at Sabetsu Island, the first thing he saw was a raging fire burning in the center of the island, with thick smoke and a pungent smell covering the entire island.

Yosuke entered the burned-out building and found a charred body lying on the ground.

Upon closer inspection, if it weren't for the six eyes on Katsuyuki Kokushi's face, Yosuke wouldn't be able to recognize him at all based on his appearance alone.

At this moment, Tsugikuni Iwakatsu was left with only a breath of life. His limbs had been completely carbonized and turned into powder, and his skin was charred black. If Yosuke had arrived a little later, Tsugikuni Iwakatsu's body would have been completely carbonized as well, and then it would have been too late to save him.

In order to stop Tsugikuni Iwakatsu from continuing to carbonize, Yosuke kept injecting his own blood into Tsugikuni Iwakatsu's body.

Thanks to the protection of Yang Jie's blood, Ji Guoyansheng's carbonization has temporarily stopped, but the situation is not optimistic.

Yosuke picked up Tsugikuni Iwakatsu and, without delay, flapped the blood wings on his back and flew towards the Butterfly Mansion.

When the Butterfly Sisters and Tamayo saw the charred remains that could barely be identified as human, they were startled.

Shinobu asked in confusion, "Master, who is this person? How did he get so badly injured?"

Yosuke replied, "Tsugikuni Iwakatsu, also known as Kokushibo."

"Kuroshibo, one of the Upper Moons of the Twelve Demon Moons? Master, why did you bring him along? Are you here to be our research material?"

Yosuke shook his head and said, "No, it was Kokushiro Iwakatsu who betrayed Kibu Muzan, and I rescued him."

Kanae asked in surprise, "Betrayal? Shouldn't the curse within him have corroded his body and killed him on the spot? How could he be burned so severely?"

Yosuke guessed, "If nothing unexpected happens, Kokushibo should have broken free of the curse within him, just like Nezuko."

Tamayo carefully examined the injuries on Tsugikuni Iwakatsu's body and said solemnly, "These injuries... they look like they were caused by Sun Breathing?"

Shinobu asked in surprise, "Really? How is that possible? Besides Yoriichi Tsugikuni in the past and Tanjiro now, who else could use the Breath of the Sun? Could it be Tanjiro who did it?"

Yosuke shook his head and said, "Tanjiro didn't do it. Kokushibo's injuries weren't caused by external wounds. They look more like a backlash."

Tamayo's pupils dilated, her face filled with disbelief: "Backlash? So, it was Tsugikuni Iwakatsu who used the Sun Breathing? How is that possible?! He's a demon, he couldn't possibly use the Sun Breathing!"

Yang Jie spread his hands and said helplessly, "I don't know the specifics either, so you'll need to do your best to treat him before we can find out the cause."

The treatment of Ji Guoyansheng has officially begun.
