Black clouds filled every corner of the sky, red-tinged black smoke mixed with blood rose into the air.

It was a truly chaotic place. If imagined with a sane mind, this would be hell. But it wasn't hell.

A young man lying on the ground, face up, began to regain consciousness.

His name was Kenshiro, a sword master on a mission. His mission was to win a war between humans and the demons of hell.

Kenshiro was a half-demon human; his head was just a skull, and his right hand consisted only of bones without flesh covering them.

As Kenshiro regained consciousness, he slowly sensed the atmosphere around him. Strangely, even though he had no eyeballs, he could understand his surroundings and vividly imagine the scene and everything around him in his mind.

Slowly, Kenshiro felt the air around him, saw with his mystical eyes, and finally, Kenshiro fully grasped the situation and environment.

In an instant, Kenshiro realized he was on a battlefield.

Kenshiro began to awaken and quickly sat up, gathering a bit of natural energy to recharge himself.

He sat silently with his body upright, both legs folded as if preparing to run, his left hand touching the ground.

But unlike his left hand, Kenshiro placed his right hand right in front of his skull face, as if reciting a mantra with that hand.

In a matter of seconds, he absorbed all the natural energy. Kenshiro then grabbed the sword and shield beside him.

When Kenshiro had fully absorbed the natural energy, something strange happened when he held his sword.

The sword, usually pitch black, turned into a blazing blood-red color.

Kenshiro felt the immense power of the red sword.

However, due to its great power, Kenshiro, who was originally standing upright, now almost fell back.

But Kenshiro prevented it by planting his sword into the ground, using it as support to prevent his body from falling back.

•••••

In another corner, there lay a demon, sprawled on the ground.

Unlike Kenshiro, Lucifer was a full-fledged demon originating from hell.

In an instant, Lucifer awoke and summoned hellish energy to recharge his life force.

Lucifer fully recovered in a flash and regained his strength completely.

Then, Lucifer summoned the spear and shield nearby, and like a magnet, his weapons instantly came to him.

After Lucifer woke up and was ready to fight again, he was startled by the sight before him.

Lucifer then said, "What is this sight? Why are none of my warriors left, and they have all even lost consciousness?"

It seemed that something had happened to cause all of this. However, Lucifer still couldn't remember the events just before.

Lucifer then spread his wings.

Wushh...

Wushhh...

Wuushhhhh...

It turned out that his wings were functioning normally as usual.

"I will make sure first, before I return to hell, that all of my enemies are also dead," said Lucifer.

Then Lucifer flew back to the center of the battlefield.

•••••

It turns out Lucifer is Kenshiro's enemy; previously, they had clashed amidst the human and demon forces.

At one point, Kenshiro had truly exerted ninety-nine percent of his power.

And it turned out Lucifer had also unleashed all the power he possessed at that moment.

Eventually, Kenshiro and Lucifer clashed weapons, and BOOOM...

Moments after their weapons clashed, a loud buzzing sound was heard by the entire army.

Suuuiiiiiiiiinggggg.....

Kretakkk...

Kretekkk...

The sound of their weapons echoed in the ears of all the soldiers.

Suddenly, all the troops, both from the human and Luciferian factions, covered their ears and momentarily ceased fighting.

It seemed that neither Kenshiro nor Lucifer was willing to give up, and neither wanted to stop.

Both of them exerted all the energy they possessed.

Until finally, suddenly, the sky, which had been ordinary or clear, turned into a sky filled with dark, thick, overcast clouds.

Several seconds passed, and their weapons continued to clash.

As Kenshiro exerted one hundred percent of his strength, so did Lucifer. Thick black and red flames erupted from their weapons.

Like the wind, the blazing black and red flames circled and expanded, aiming at all the troops present.

Unnoticed, Kenshiro and Lucifer were also thrown back by it.

And finally, Kenshiro and Lucifer both collapsed unconscious.

Not only Kenshiro and Lucifer, but all the dark forces and all the human troops also fell unconscious.

•••••

Returning to the present, Lucifer flapped his thick black wings and flew back to the center of the battlefield.

Upon arriving at the exact spot where he and Kenshiro clashed with one hundred percent of their strength, Lucifer finally remembered.

It turned out that the reason all the troops fell without a trace was the tremendous friction between his weapon and Kenshiro's.

"Wait a minute, if all these troops fell without a trace, did that bastard Kenshiro also perish by his own doing?" Lucifer said, looking around.

"But why is Kenshiro nowhere to be found? Did he get incinerated by the thick black and red flames earlier?" Lucifer grew even more curious about Kenshiro's whereabouts.

Then Lucifer paused at that point for a moment, ceasing the flapping of his wings.

Lucifer set aside his spear, then he sat for a moment, attempting to emit a black aura that slowly spread in all directions.

Quickly, the entire battlefield was shrouded in his black aura.

Finally, Lucifer pinpointed Kenshiro's location with his black aura.

However, as Lucifer sensed Kenshiro's presence, there was a strange energy that he had never seen before, and it enveloped Kenshiro's weapon.

Lucifer immediately retrieved his spear and stood up, spreading his wings once again.

Without hesitation, Lucifer flew towards Kenshiro at lightning speed, driven by a strong desire to kill.

•••••

Meanwhile, on the other side, Kenshiro was still puzzled by the blazing blood-red sword that he had never seen before.

"What kind of sword is this, why does it seem to have a soul of its own, and is this really the sword I usually use?" Kenshiro asked the blazing blood-red sword.

But another strangeness occurred here.

Kenshiro felt an aura suddenly emanating from the blazing blood-red sword.

Then the aura of the sword appeared to be like a demon's aura with a wide grin.

Before Kenshiro could delve deeper and inquire further into the aura of the sword, he was startled by a black aura approaching him.

Kenshiro was reminded once again that he was now fighting Lucifer, who was incredibly powerful.

Not long after Kenshiro sensed the black aura, a vaguely discernible black figure, cloaked in thick black aura, dashed towards him at lightning speed.

The figure, with wings, wielding a spear, sporting a tail, and emanating an aura of immense bloodlust, was Lucifer.

Without much time to spare, Kenshiro realized that the figure was indeed Lucifer.

Kenshiro quickly stood up and attempted to lift the blazing blood-red sword again.

Struggling and full of difficulty, Kenshiro lifted the sword with all his strength.

However, with his unwavering fighting spirit and determination, he overcame the difficulty of lifting the sword.

Finally, Kenshiro managed to lift the sword with his right hand, while his left hand held the shield, standing tall, facing the direction from which Lucifer was approaching.

For a moment, Kenshiro absorbed the remaining natural energy around him and channelled it throughout his body.

Once enveloped in the energy, Kenshiro immediately ran towards Lucifer's direction.

"LUCIFERRRRRRRRRR...."

•••••

Not to be outdone, Lucifer, upon hearing Kenshiro's shout, was also ablaze with fervor and eager to engage Kenshiro once again.

"KENSHIIIIROOOOOO..."

Wwuuuuuuushhhhhhh.....

As quick as lightning, Lucifer surged towards Kenshiro and thrust his spear forward.

With his full strength, Kenshiro was equally determined not to be defeated. He swung his sword with a confident arc, "hyaaatttttt...."

An extraordinary explosion occurred as the two weapons collided, and Boooooommmmm....
