Rengoku Shinjuro's Shock × Mugen Train's Luxurious Ambush

Kyojuro would never forget the words his mother spoke to him on her deathbed, "Helping the weak is the inherent duty of the strong."

"And Kyojuro, your mission is to take responsibility and fulfill it."

What is weakness, and what is strength?

His mother, Ruka, didn't explicitly tell him, but Kyojuro knew that people like him and his father, Shinjuro, were by no means "weak" compared to ordinary people struggling to make a living in a cruel era overrun by Demon.

Kyojuro also knew that his father had read the "Book of Successive Flame Hashira" and had personally heard him complain angrily and dejectedly, saying, "A person's abilities are predetermined at birth. There are only a very few geniuses; the rest are nothing but worthless dregs."

There was a time when Kyojuro thought the same way. His younger brother, Senjuro, thought the same way, as did those so-called "genius swordsmen" who wanted to be his "stepsons." They lacked "Swordsmanship skills," but... that didn't mean that Senjuro and the others couldn't contribute their share to the "demon-hunting cause" in other ways!

Rengoku Kyojuro, sword in hand, pushed open the door and stepped into the courtyard. He could vaguely see his younger self in that familiar space, playing with his brother, catching butterflies with his mother, and being patted on the head by his father... He took a deep breath, drew his sword, and pointed it at the man holding a sake jug on the wooden veranda. He shouted, "Father, please pull yourself together!"

Fire is meant to burn, it's meant to be outspoken... Hearing the door open, a small, timid-looking Kyojuro peeked out... Shinjuro tilted his head back, took a swig of sake, and coldly looked at him. "Get out!"

Rengoku Kyojuro stepped forward, his Nen Qi infusing his Nichirin Sword, which surged with flames. His gaze was resolute as he declared, "Father, please pull yourself together!"

"Crack!" The sake bottle flew over, grazing Kyojuro's ear and smashing against the wall behind him, shattering on the spot!

Sake spilled onto the wall... Shinjuro glared angrily at Kyojuro and yelled, "You think you're so great just because you became a pillar with a few pages of tattered paper, huh?"

"Senjuro, bring me your sword!"

The alcohol fueled his anger, and Shinjuro stood up coldly, seemingly regaining some of his former imposing manner in that instant!

Senjuro clung to the doorframe, cautiously glancing at his elder brother, then at his father. His already sour face immediately contorted into a wide, awkward expression...

"Give it to him." Kyojuro tilted his head and smiled kindly, "Trust me."

"Yes." Senjuro swallowed hesitantly, then handed his sword to Shinjuro with a hint of worry.

Shinjuro reached out and grabbed it; it felt so unfamiliar. After swinging it around a bit, he gradually regained his feel for it... Kyojuro waited quietly until he stopped, took three steps in two, stepped off the wooden corridor, and casually swung his sword, wreathed in flames, at him... For the first time, he understood why Lord Eiichiro had been so unfazed by his full-force "sword technique" in the Wisteria grove outside the Master's courtyard... It was too weak, too slow, and the temperature of the flames was too low!

Rengoku Kyojuro was disappointed. With the word "Entangle" on his body, he faced Shinjuro's angry attack, which was meant to teach him a lesson. He swung his sword back and easily knocked the sword out of Shinjuro's hand. Then, he placed his Nichirin Sword against Rengoku Shinjuro's neck.

"This..

The confrontation ended in a mere instant.

Senjuro expected his elder brother's sudden "admonition" to provoke a strong backlash from their father... but the result told him... his father actually lost!

While it's true that a disciple doesn't necessarily have to be inferior to his master, and a master doesn't necessarily have to be more virtuous than his disciple... Senjuro, who had been personally trained by Shinjuro, was deeply ingrained with his father's strength... Was he the former "Flame Hashira," or the true "Flame Hashira" who had fully mastered all the sword techniques of "Flame Breathing"?

He wasn't the older brother who had only learned "Breathing Style" from three incomplete pages of a scroll—a half-baked attempt.

But today, this "half-baked" guy defeated his powerful father in a head-on, one-round battle!

"Hiss—" A maid secretly witnessed this scene and stared wide-eyed in disbelief...

In the courtyard, two strikingly similar faces stared at each other, one disappointed, the other shocked.

The latter seemed to finally come to his senses, and said in a hoarse voice, "You're not the son I know."

Rengoku Shinjuro seemed to have finally pulled himself together from his despondency, looking intently at Kyojuro and saying, "Your power, your fire, is beyond what ' Flame Breathing ' can achieve."

"Who... who taught you?"

The reason why Shinjuro has been depressed all these years, besides the death of his wife Ruka, is mainly because... he clearly knows that the upper limit of "Flame Breathing" is simply not enough to fight against Muzan Kibutsuji. As it turns out, the <Book of Successive Flame Hashira> also records... that "Flame Breathing" at its limit cannot even kill some powerful Upper Rank. This is another important reason why, after Ruka, it dealt a heavy blow to Shinjuro's spirit.

"It's the sun." Kyojuro sheathed his sword, clasped his hands together, and looked up at the sky. The evening sun was setting, not yet sinking Heavenly Abyss, its brilliant rays painting half the sky red, draping him in a Rosy Garment...

The Sun-Earring Boy smiled at the stunned Shinjuro and said, "Father, I saw the sun."

Zhen Shinjuro:

As if a fishbone were stuck in my throat, I was momentarily speechless.

"Whoosh~"

The wind stirred the blond hair of the father and his two sons, causing them to sway, and the courtyard fell silent once more...

After a moment, Shinjuro asked, "What is the name of the sun?"

Kyojuro replied truthfully, "Kamado Eiichiro."

The tip of his white haori was tinged with red. Rengoku Kyojuro smiled and passed on the words Roy had given him to Shinjuro, saying, "The sun can be me, you, him, or anyone who holds a righteous and positive heart."

After a long pause, Shinjuro laughed. Beside him, Senjuro was stunned. This was the first time the Sun-Earring Boy had seen a smile on his father's face since his mother's death. Then... Shinjuro's laughter grew louder and louder, more unrestrained, until finally he was laughing with his hands on his hips, a few tears even welling in his eyes...

"Interesting, very interesting, Kyojuro. Ask him if I can really do it too?"

"If I can do it, you can too, and Senjuro certainly can as well."

J

"Hahaha...

On this day, a few joyful auras filled the air above the Rengoku Family... The servants who knew the situation of their master's family were all as if they had seen a ghost, dizzy and incredulous.

They whispered among themselves, or inquired quietly about Lord Kamado Eiichiro...

Little did they know, the mysterious and unpredictable Kamado Eiichiro, whom they spoke of, had already stepped onto a speeding train.

That night.

Passing through the colorful Dream Passage, we arrive at the familiar Sea of Cognition.

Without lingering, he pushed open the "Demon Slayer" gate and entered the Demon Slayer world again. Following the clues provided by Ubuyashiki Kagaya, he arrived at Carriage 7 and plopped down opposite Enmu, Rui, and... Upper Rank Three Akaza.

Smiling at the group, he said, "Three of you, would you mind if we had an extra seat?"
