Awaken the Sharingan, kill Muzan and open your Mangekyō!

"The tenth pillar of the Demon Slayer Corps, Uchiha Isha!"

Uchiha Isha responded lightly.

"That's really great."

"This is my first time facing the 'Sun Pillar'!"

""Let me see how strong you are, the... Sun Pillar of the Demon Slayer Corps!"

Akaza showed a grim smile on his face.

After saying that, he took his own fighting stance.

His snowflake-shaped technique was already unfolding under his feet.

Destruction Killing·Luo Needle!

This is the core of Akaza's blood demon technique.

Luo Needle can sense the opponent's fighting spirit like a compass, making its own attack and evasion actions as accurate as being attracted by a magnet. The stronger the opponent's fighting spirit, the stronger the reaction of Luo Needle, and the higher the corresponding strength and accuracy.

However, for opponents without fighting spirit or who have reached the supreme realm (transparent world), Luo Needle cannot sense them.

"How pathetic!"

Facing Akaza who was performing the technique, Uchiha Isha felt sorry for him.

Unlike other upper-rank demons, Akaza forgot everything about his human life after becoming a demon.

He became stronger, and also forgot what goal he wanted to protect.

However, his blood demon technique and attire were filled with everything he cared about most when he was a human.

The snowflake pattern of Akaza's Nara needle technique was the pattern of his lover Koyuki's hairpin.

And his pink hair color was exactly the color of Koyuki's favorite kimono.

The name of his blood demon technique was the name of the fireworks he and Koyuki had seen.

But Akaza himself had forgotten all of this.

Isn't this a kind of irony?

"Do you still have time to sigh?"

Akaza snorted coldly.

Uchiha Isha's inexplicable sigh made him subconsciously feel a little unhappy

""Destruction Kill·Air Style!"

Akaza immediately punched the air at the position where Uchiha Isha was.

In an instant, six huge punches turned into powerful shock waves and were about to hit Uchiha Isha heavily.

Facing the fierce attack, Uchiha Isha had no intention of resisting at all.

Under the dynamic vision of the Sharingan, coupled with the transparent world that had already opened up when Akaza attacked.

Akaza's attack route has been completely seen through by him.

He took small steps like this, twisting his waist with some ease, and narrowly avoided the incoming punches one by one.

"How is it possible that he dodged my attack so easily?"

Seeing this scene, Akaza was shocked.

His attack was clearly launched by locking Uchiha Isha's fighting spirit. There was no reason for Uchiha Isha to dodge.

The most he could do was to launch a powerful attack to block his attack.

Hmm?

No!

Akaza suddenly found something wrong.

At this moment, the fighting spirit he detected from Uchiha Isha seemed to have changed.

The fighting spirit on Uchiha Isha's body has been completely restrained, and no trace of fighting spirit can be seen.

This change can only have one reason.

He has only seen it in one person.

That is... Upper Moon One Kokushibo.

This is a powerful existence that he has challenged several times over the past few hundred years but was defeated every time.

And the reason why the other party was able to defeat him was because he had reached the supreme realm that he had never reached.

So, did Uchiha Isha also reach that realm?

When Akaza was shocked. At this moment, Uchiha Isha was... Very happy.

The source of his joy lies in his harvest at this moment.

His Sharingan seems to have successfully copied Akaza's blood demon art.

This is the first time in history.

Previously, when he copied the blood demon art of other lower-rank demons, he basically ended in failure.

But this time, he succeeded.

It seems that his previous guess was not wrong.

His Sharingan can copy abilities such as fighting techniques and breathing techniques that humans can master from demons.

There is no need to kill demons and get the opponent's energy, so that the opponent's blood demon art can be obtained directly or indirectly.

Even if there are differences between the moves he used and the original blood demon art copied from Akaza.

But in terms of power, there will not be much difference.

As long as he is strong enough and his fighting spirit is strong enough.

At this point, his physical fitness, which is so strong that it can be compared with that of demons, also played a significant role.

"Have you reached the highest realm?"

Akaza didn't know that his blood demon art was successfully copied by Uchiha Ixia, a human.

After making a certain guess, he clenched his fists at this moment, with shock and jealousy in his eyes.

It was ok that the highest realm that he had spent hundreds of years to reach was reached by Kokushibo early.

Now even Uchiha Ixia, a human, has surpassed him.

This makes him like a clown.

His efforts over the past hundreds of years seem to have become useless.

"What do you think?"

Uchiha Isha held the Sun Blade in front of him and chuckled.

"Just try and you will know."

Akaza's eyes turned red.

Whether Uchiha Ixia really reached this supreme realm, his next attack could further prove it.

And even if Uchiha Ixia really reached the supreme realm, it did not mean that he would lose to Uchiha Ixia.

Even if they both reached the supreme realm, there was still a gap in strength.

He did not think that Uchiha Ixia would be another Kokushibo.

This was impossible!

""Destruction Killing·Annihilation Style!"

Akaza punched again.

He threw a destructive punch.

The air exploded due to the huge pressure of the punch, and there was a roar.

At this moment when the compass needle was ineffective

, Akaza could only rely on his own eyes, combat experience and judgment.

He didn't think that Uchiha Isha could easily dodge this punch.

In fact, it was true.

The powerful power and range attack of the Destruction Killing·Annihilation Style also forced Uchiha Isha to counterattack.

""Sun Breathing Type 5: Train!"

Uchiha Isha launched a counterattack.

The next moment, his body jumped high and spun in the air.

However, rather than saying that he took the initiative to jump up, it would be better to say that his body followed the attack of the Sun Blade.

And this jump also allowed him to cleverly avoid the incoming Destruction Killing Type.

When his body fell, he had already appeared behind Akaza.

The Sun Blade in his hand had already slid across Akaza's back, leaving a huge wound.

This was when Akaza reacted and dodged immediately.

Otherwise, this knife would have split him in half.

"Well——"

""Damn it!"

Akaza let out a hoarse roar.

He had never expected that his sure-win attack would be easily avoided by Uchiha Isha.

He himself was even hurt by Uchiha Isha's attack.

Fortunately, he sensed the fatal danger and did not let his body be split in half by Uchiha Isha's Sun Blade.

Even so, the knife wound on his back made him feel extremely painful and miserable.

"Is this the red sword that Lord Muzan mentioned?"

"It is indeed... It is indeed an extremely dangerous existence."

Akaza's eyes flashed with ferocity.

There was a trace of fear and dread in his eyes.

In addition to informing Uchiha Isha of the existence and the Sun Breathing he used, his immediate superior, Muzan Kibutsuji, also mentioned the so-called 'Red Blade' to him, asking him not to be hit by the Red Blade's attack because of carelessness.

Otherwise, even if he is an upper-rank demon, he is not strong enough to be chopped.

His current situation is indeed the case.

The burning sensation and destructive power brought by the Red Blade made it impossible for the minor injuries on his back to heal.

The surrounding flesh and blood were also affected. Even if this would not affect him as a whole, it would become a considerable hidden danger.

If there were a few more such moves, his own strength would suffer huge losses.

"Do you still have time to be shocked?"

Seeing that Akaza did not continue to attack because of the wound left by the red sword on his back,

Uchiha Ixia, who once again copied Akaza's blood demon art, took the initiative to attack.

He used the Sun Breathing Seventh Type: Flying Wheel Yangyan to slash at Akaza's neck.

The Sun Wheel Sword in the red sword state was about to fall on Akaza's neck with flaming sword energy.

"Don’t even think about it!"

""Destruction Killing·Foot Style·Flowing Flash Group of Lights!"

Akaza dodged Uchiha Isha's slashing blow with his head bent down.

Then, he lifted his right foot and launched a series of fierce kicks at Uchiha Isha behind him.

Just like the previous Destruction Killing·Air Style.

Every kick brought by the Destruction Killing·Foot Style·Flowing Flash Group of Lights brought an extremely powerful shock wave. At such a close distance, even if Uchiha Isha could see Akaza's attack with the help of Sharingan and the Transparent World, he would still be affected.
