Chapter 3 : Profound Truth!

"This kind of regenerative ability is something I desire more and more." Orochimaru extended his tongue and licked his lips, his eyes filled with greed.

"Swift regeneration? Or a similar capability?" Aizen pondered thoughtfully, acknowledging that the other party's level wasn't of low caliber.

Inside the Butterfly Estate, Tanjiro's forehead glistened with sweat, his anxiety palpable. "Is this the pressure emitted by Kizuki? It's intense pressure!"

Zenitsu quivered, while Inosuke clenched his fists silently.

[Continuing the scene!]

[Rengoku Kyojuro remarked, "Why attack those who can't move?"]

[Akaza wiped the remaining blood off his arm and calmly explained, "I figured he'd hinder my conversation with you. That's all."]

[Following that, Akaza tried to recruit Rengoku Kyojuro as a demon, only to be firmly declined.]

[After introducing himself, Akaza elaborated, "Do you know why you can't reach the highest level? It's because you're not a demon. You can't attain eternal life. Otherwise, if you lack a hundred years, it will take two hundred. If you can't achieve it in two hundred, it'll take five hundred. Success will come eventually!"]

"Eternal life??" Orochimaru was thoroughly excited; his body trembled, and he yearned to enter this world at that very moment.

People across various realms were equally astonished.

Even though their own world boasted higher power levels, the allure of immortality remained undeniable!!

"To think a small world harbors secrets of immortality. I wish to conquer it!" exclaimed a certain blond figure from a certain World.

[Rengoku Rengoku raised his longsword. "I decline!"]

[Noticing a faint smile on Akaza's lips, he raised his hands. "So be it! The technique unfolds!!"]

["Destruction and slaying, Rending Flash!!"]

[Suddenly, an icy crystal-like pattern gleamed beneath his feet, erupting with intense and rich demonual energy.]

[A thunderous boom followed as the two figures clashed, stirring countless plumes of smoke.]

[On screen, the figures became entirely indistinct.]

[A cacophony of roars resonated as red and blue flashes darted like lightning in every direction.]

"I underestimated it. The physical prowess is comparable to a Jōnin, if not stronger. And I doubt the flames on his blade are ordinary."

Kakashi felt a tinge of fear. Judging by the opponent's speed, typical Jōnin techniques were nearly ineffective, unable to make contact.

The power level of this world wasn't as low as initially thought.

[Whistling through the air, blocking, slashing, twisting and turning—each sought the other's weaknesses. The two perfectly showcased the essence of Taijutsu!]

[Akaza suddenly leapt, his fists enveloped in ice-blue demonual power, fiercely descending in a flurry of blows.]

"Destruction and killing, Void Form!"

[Innumerable invisible fists hurtled towards Rengoku Kyojuro!]

[Unfazed, Rengoku Kyojuro quickly discerned the threat, exhaling through his mouth, infusing his sword technique.]

"Breath of Flame, Form of Stubbornness, Dance of the Sacred Flame!"

[Sudden surges of flames erupted from his blade, akin to a massive wave countering the transparent fists.]

[Observing this, Akaza ceased his barrage and landed on the ground.]

[In the next instant, Rengoku Rengoku traced a fiery arc, appearing before Akaza and slashing down with his blade.]

[Thunderous, echoing booms resounded!]

[Two colossal forces collided anew!]

[Akaza paid no mind to using his fists against the razor-sharp blade, his third form, the Breath of Winding, showcasing remarkable regenerative abilities.]

[From the ground, they dashed into the forest, emerging seconds later, leaving two afterimages in their wake!]

In the world of Ninja, Naruto's blood surged.

In the realm of pirates, Luffy eagerly awaited a personal fight, bouncing with excitement.

"Such bodily control has reached perfection. If he were to study at the Marines, he could become a Vice Admiral!" Sengoku lamented, wishing that such a noble individual would join their ranks.

Akaza's eyes were a mix of complexity. "Why not become a demon? Then the two of us could continue to clash."

[Continuing the scene, after dozens of exchanges, Akaza remained unfazed, whereas Rengoku started to falter.]

Anyone discerning could see their different constitutions.

A demon's physique far exceeded that of a human!

[Rengoku did not yield, the flames from his Breath of Flame continued to surge towards Akaza.]

[However, after a few rounds, Akaza punched Rengoku Kyojuro's left eye!]

[Blood dripped as Rengoku Kyojuro's left eye lost sight entirely.]

[Undeterred, he pressed on, relentlessly attacking!]

"Breath of Flame, Five Forms: Flame Tiger!"

[A fierce, fiery tiger materialized, roaring and lunging at Akaza!]

"Destruction and killing, Chaotic Void!"

[A massive explosion of icy-blue demonual power manifested before Akaza, promptly neutralizing the flame tiger.]

[The two collided in an instant, swords and fists interweaving before separating once more.]

[The battle abruptly halted; the two stood opposite each other.]

[Suddenly, a long gash appeared on Akaza's upper body, swiftly healing before their eyes!]

[On the other side, Rengoku stood rigid, blood trickling from his mouth. His grip on the blade trembled, and his energy waned!]

In this round just concluded, humanity had lost!

In the world of Demon Slayers, Tanjiro leaped off his hospital bed, urgently crying out, "Mr. Kyojuro! Run! Leave us behind!"

Within the Demon Slayer Corps headquarters, Mitsuri was already sobbing.

But Rengoku Kyojuro remained composed and unshaken, as if the person in the video wasn't himself.

Inside Hueco Mundo, Aizen leaned on his hand, speaking lightly, "Is this the victor?"

In the livestream, Naruto clenched his fists, wordless!

"So feeble, a mere failure…" Kizaru murmured, eyes unmoving.

Many were disappointed.

Although the battle was exhilarating, it wasn't unexpected.

But just then…

[Boom!]

[Severely wounded, Rengoku ignited an immense aura again, flames enveloping him in a blaze of glory!]

[It was like a sun bursting forth in the darkest night!]

[Rengoku Kyojuro raised the Sun Breathing sword once more!]

[At that instant, his eyes ignited anew! That spark represented the absence of fear, a determination to triumph regardless of death!]

[The music crescendoed!]

["I am Flame Hashira, Rengoku Kyojuro!"]

["I shall fulfill my duty! None here shall perish!"]

["Breath of Flame, Profound Truth, Ninth Style: Rengoku!"]
