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

Yosuke gently comforted him, "There's no need to be so serious right now. Kibuyaku Muzan hasn't found that blue spider lily yet, and even its existence is questionable."

Yosuke had also searched for the blue spider lily. In his memory, the blue spider lily only blooms during the day and for a very short time. Yosuke specially hired some humans to search for it, but he found nothing.

Even with Yosuke's comforting words, the expressions on everyone's faces did not lighten.

Naosai Ubuyashiki said solemnly, "We must prepare for the worst in everything. If Kibuy Muzan finds the Blue Spider Lily, it will be too late. We must put the encirclement and suppression of Kibuy Muzan on the agenda!"

"Ancestor Yosuke, you fought Kibu Y Muzan head-on, so do you have a general understanding of Kibu Y Muzan's strength?"

Yosuke began to explain Kibuy Muzan's abilities to everyone.

"Muzan's body contains multiple vital organs. By possessing a brain and heart that exceed the capacity of an individual, Muzan has an extremely abnormal regenerative speed and unlimited stamina. Muzan can regenerate the moment an ordinary Nichirin Blade cuts into his body."

Furthermore, his body generates spikes filled with Muzan Kibutsuji's blood; a single strike can destroy an opponent's cells, thus killing them.

The only known Blood Demon Art by Muzan Kibutsuji is called Blood Demon Art: Black Blood Thorns. It can create a large number of black thorns using blood, and also generates a powerful, wide-area shockwave centered on himself, possessing extremely strong physical destructive power.

Upon hearing Yosuke's description of Kibuy Muzan's strength, everyone's faces darkened, and the atmosphere became extremely somber.

Chapter 15 Bait

Inside the main house of the Ubuyashiki family mansion, everyone fell silent after hearing Yosuke's explanation of Kibuy Muzan's abilities.

Fighting the demons created by Kibuy Muzan was already difficult enough, let alone Kibuy Muzan himself.

When the battle begins, the Demon Slayer Corps will inevitably face a large number of demons created by Muzan Kibutsuji. So, who will face Muzan Kibutsuji?

Naosai Ubuyashiki, the lord, encouraged him, "Don't be so discouraged. Since our ancestor Yosuke chose to come here, he must have a plan in mind, right?"

Yosuke nodded: "The key to this battle is Yoriichi Tsugikuni!"

Everyone turned to look at Yoriichi Tsugikuni, who had been sitting quietly to the side.

As the water pillar appeared, Eriko Hon's face turned ashen. "Are we going to leave Yoriichi-san to face Muzan alone? Absolutely not! Yoriichi-san is, after all, a human; it's far too dangerous!"

When no one in the Demon Slayer Corps knew how to use Breathing Techniques, it was Yoriichi Tsugikuni who taught him everything without reservation. To the Water Pillar Eriko Tokimoto, Yoriichi Tsugikuni was like a master, and as a disciple, Eriko Tokimoto didn't want Yoriichi Tsugikuni to face danger alone.

Yosuke shook his head and said, "Of course I'm not letting Yoriichi face Kibu Muzan alone. I will face Kibu Muzan with him. Right now, the most important thing is you!"

"Us?" The pillars asked, puzzled.

“Yes, when Yoriichi and I were fighting Kibu Muzan, we needed an environment where no one would disturb us, so we needed you to hold off Kibu Muzan’s army of demons. But you are too weak to do it.”

Upon hearing Yosuke's assessment of them, all the Pillars were unconvinced. Since mastering the Breathing Technique, they had been able to deal with demons with ease, so how could they be as incompetent as Yosuke described?

"Don't be so angry. I'm just stating the facts. On the day of the battle, there won't be just one or two ghosts, but an entire army of evil spirits, hundreds or even thousands of them. Ask yourselves honestly, could you have done that?"

The crowd fell silent once again, a picture flashing through their minds: hundreds or thousands of evil spirits charging towards them. Could they really stop them?

"Therefore, before the final battle with Muzan Kibutsuji, you should try your best to improve your strength, and it would be best if you could activate your Demon Slayer Mark and Crimson Blade to enter the Transparent World."

Everyone was puzzled when they heard new terms from Yang Jie.

Yosuke sighed inwardly. The five people in front of him were the forerunners of the Demon Slayer Corps in later generations. Terms like Demon Slayer Marks, the Transparent World, and the Crimson Blade were completely unfamiliar to them now.

When the final battle begins, how many of those present will survive?

"I think Yoriichi is most familiar with the markings and the transparent world, after all, he is a born marking warrior."

Yosuke shifted the topic to Yoriichi Tsugikuni and explained, "I don't actually know much about the markings and the Transparent World. When my body temperature exceeds 39 degrees and my heart rate exceeds 200, the markings on my forehead will expand and my physical fitness will greatly improve."

The Transparent World requires activating the Mark to enter. The Transparent World greatly enhances the speed of predicting movements and dodging attacks, and also allows you to clearly see the rise and fall of your opponent's lungs and the flow and contraction of blood vessels, as well as the speed of your own muscle contraction.

As for the Crimson Blade, by exerting tremendous force in the grip or through the collision of weapons, raising the blade's temperature, it can be transformed into a "Crimson Blade." The Crimson Blade significantly increases the damage inflicted on demons, and the regeneration rate of parts of demons struck by it decreases.

After hearing Yoriichi's explanation, the Pillars were completely confused except for how to activate the Crimson Blade.

Ubuyashiki Naosai smiled slightly and said to the Pillars, "In that case, everyone should focus on your training recently. When everything is ready, the encirclement and suppression of Kibu Muzan will officially begin!"

Apart from Yosuke and Ubuyashiki Naosai, everyone else left the main house.

"Ancestor Yang Jie, do you have a plan on how to seduce Kibu Muzan?"

Yosuke's lips curled into a smile: "What Kibuy Muzan wants most is the Blue Spider Lily. Since that's the case, let's spread the news that we've already obtained the Blue Spider Lily to lure him here!"

Naosai Ubuyashiki shook his head: "The Demon Slayer Corps has been entangled with Muzan Kibutsuji for over a hundred years. I understand his personality quite well. Muzan Kibutsuji is a very cautious person. He won't fall for a trick unless he's certain that the Blue Spider Lily is indeed in our hands."

Yosuke frowned, somewhat guessing what Ubuyashiki Naosai was thinking: "Naosai, you don't mean to..."

"That's right, let's use me as bait. Kibu Muzan has always wanted to exterminate the Ubuyashiki clan, who formed the Demon Slayer Corps, but thanks to our clan's ability to 'foresee the future,' we have avoided the crisis and are living in seclusion in these deep mountains. I believe that as a thorn in Kibu Muzan's side, he will be happy to end my life with his own hands."

Yosuke immediately rejected Naosai Ubuyashiki's suggestion: "No, if you die, who will command the Demon Slayer Corps?"

Naosai Ubuyashiki smiled slightly, showing no concern for his own life or death: "My son, Terusai Ubuyashiki, will succeed as the head of the Ubuyashiki family and continue to command the members of the Demon Slayer Corps in battle."

I could sense my impending death. In the final moments of my life, to contribute my last bit of strength to the Demon Slayer Corps would be a fitting end.

Yosuke remained silent, still pondering whether there were other ways to replace becoming bait for Kibuy Muzan.

“Ancestor Yang Jie, this is the best way. We cannot afford the slightest mistake in the final battle, and it is also time to end this centuries-old karmic entanglement.”

Although Naosai Ubuyashiki's eyes were lifeless, his firm voice moved Yosuke deeply.

Yosuke sighed dejectedly, "Naozai, you address me as an ancestor, yet I am powerless to help you. I, as your ancestor, have truly failed in my duty..."

“Everyone has their own destiny. As long as I can kill Kibu Muzan and end this tragic chain of fates, I can die without regrets.”

Naosai Ubuyashiki smiled slightly, took out a bottle of sake and two cups, filled them, and placed one of the cups in front of Yosuke.

Concerned about Naosai's health, Yosuke advised, "Naosai, you can't drink alcohol because of your health."

"It's alright, Ancestor Yang Jie. In the final stage of my life, I also want to indulge myself once in a while and have a good drink with Ancestor Yang Jie. Just this once, okay?"

Naosai Ubuyashiki's last words had a childlike, coquettish tone, and Yosuke stared blankly at Naosai's face.

That's right. Even as the leader of the Demon Slayer Corps, Naosai is only in his early twenties.

Yosuke raised his wine glass, clinked it with Naozai's, and drank it all in one gulp.

"Okay, just this once."

Chapter 16 Blood Breathing? First Form? Crimson Corruption

Time flies.

All members of the Demon Slayer Corps were training under a tense atmosphere.

Yosuke wasn't idle either; he found Yoriichi Tsugikuni and asked to learn the Breath of the Sun.

Yoriichi Tsugikuni did not refuse Yosuke's request out of embarrassment because Yosuke was a demon, but instead gladly accepted Yosuke's request and imparted all his knowledge of the Breath of the Sun.

However, when Yosuke obtained the complete method of practicing Sun Breathing, he felt as if his meridians were being scorched and melted by the sun when he tried to practice it on his own, causing him immense pain.

Yosuke was terrified because when he practiced Sun Breathing, he felt the presence of death. His sixth sense told him that if he continued to practice Sun Breathing, he would definitely die.

When Yosuke practiced other breathing techniques, they were very smooth, but their power was indescribable, not even one-tenth of the power of Sun Breathing, and they did almost no improvement in his combat power.

Yosuke summoned the long-lost system and asked why he could not practice the Breath of the Sun.

"Ding, host, please cherish your life. Sun Breathing imitates the power of the sun, and the sun is your weakness. Practicing Sun Breathing is not conducive to suicide."

Yosuke was filled with regret at missing out on the world's strongest breathing technique. Even if he obtained a breathing technique through the system, it wouldn't improve him at all if it wasn't the Breath of the Sun.

"Ding, system notification: If the host is not satisfied with the breathing method in the system, he/she can develop a breathing method that suits him/her through his/her own efforts. The system only assists the host to become stronger and does not mean that the host has to rely on the system completely."

The system's words rekindled Yosuke's hope. The system was right. He couldn't learn the Sun Breathing technique, and other breathing techniques were too weak for him. So why not create his own breathing technique?

Even Kokushibo has his own unique Moon Breathing technique, so there's no reason why I can't do it.

And so, Yosuke began to cultivate and create a breathing method that suited him.

Seeing Yosuke's hard work, the other pillars worked even harder so as not to be outdone.

Even Tamayo, in order to play a role in the final battle, began researching a poison specifically targeting demons.

In the small Ubuyashiki mansion, everyone began to engage in fierce competition.

A month has passed, which is just a blink of an eye for Yosuke.

One evening, Kenjiro Kazeshiro, who had always regarded Yosuke as a thorn in his side, found Yosuke.

Although he no longer resorts to violence at the slightest provocation like before, Kento, the Wind Pillar, still doesn't give Yosuke a friendly look.

Kento Kazehachi looked at Yosuke with a provocative expression: "Judging from your appearance, you're thinking of creating a derivative breathing technique of Sun Breathing, right? How about a spar?"

Yosuke, who had already begun to get inspiration for the new breathing technique, naturally wouldn't refuse the challenge proposed by the Wind Pillar, Kento, and immediately agreed.

Kento Kazehachi stared fiercely at Yosuke, slowly drawing his Nichirin Blade: "If I kill you in this sparring match, don't blame me!"

Yosuke gave a disdainful smile: "If you can do it, then give it a try!"

Kento Kagami gripped the Nichirin Blade with both hands, the pale green blade slowly turning red.

Yosuke chuckled, still wondering why the Wind Pillar, Kento, would challenge him. It turned out that Kento had mastered the Crimson Blade.

However... I can easily raise the temperature of my Nichirin Blade by gripping it!

Yosuke also drew his Nichirin Blade, its powerful grip transforming the blade into a striking red.

"Wind Breathing? First Form? Dust Whirlwind? Slash!"

Kento Kazekage made the first move, rapidly approaching Yosuke. His Nichirin Blade, accompanied by spinning wind blades capable of easily slicing through the ground, charged towards Yosuke.

Yosuke held his Nichirin Blade horizontally in front of his chest, and Kento Ueji's Nichirin Blade tipped against Yosuke's blade. The powerful wind pressure caused a strong gust of wind to sweep through the entire courtyard.

The commotion attracted the attention of the pillars who were cultivating nearby.

"What's going on? Why are Kento and Yosuke fighting?"

Watching Kento Kamijou and Yosuke fighting each other, Eriko Motomoto, the Water Pillar, asked Raiki Sakatani, the Lightning Pillar, with a puzzled look.

"I didn't arrive much earlier than you, so I don't know the specifics either." Although Raikage Sakatani answered Eriko Tokimoto, his eyes never left the battlefield.

"I think the two of them are probably sparring, since neither of them is showing any killing intent!" With his arms crossed over his chest, Rengoku Shinzuka Sho was most sensitive to the aura and noticed that neither of them was showing any killing intent.

Eriko Tokimoto nodded, "I see," and then continued, "Who do you think will win this battle?"

"Ubuyashiki Yosuke!" x3

"Hey, why doesn't anyone think Kento will win?"

Daigo Iwahashima explained, "Although it seems like Kento is overwhelming Yosuke Ubuyashiki, if you look closely, Yosuke Ubuyashiki isn't using any special abilities other than basic swordsmanship. He's still managing to easily defend against Kento's attacks. It's only a matter of time before Kento is defeated."

The perspective shifts back to the battle between Yosuke and the Wind Pillar, Kenji.
