Where Did She Come From?

Clang! Clang! Clang! Clang!

Four Nichirin Blade slashed at Akaza 'Akaza limbs, causing him to pause slightly.

The next instant.

Swish! Swish! Swish! Swish!

The Nichirin Blade, still blazing with flames, once again slashed through Akaza's limbs.

Finally!!

Except for Tanjiro, whose eyes remained devoid of emotion, the other four couldn't help but reveal a hint of joy in their eyes.

If we've fought this far, things will get easier from here on out, as long as we don't let Akaza regrow his limbs and head!

But, the next moment.

Amidst the puzzled gazes of the crowd, only the main body of the torso trembled slightly, and then...

"Quick, hide behind me!"

Giyu shouted, and Obanai, Inosuke Zenitsu beside him immediately slashed at his back.

On the other side, Tanjiro also took a step backward.

The next instant.

Swoosh! Swoosh! Swoosh! Swoosh!...

Hundreds of fist-shaped shockwaves shot outwards from Akaza as the center.

Giyu continued to retreat while lowering his sword downwards.

" Eleventh Form ·Nagi!

When the shockwave reached Giyu, it seemed to be affected by an unknown force, and they all dissipated one by one.

But there were just too many shockwaves. One dissipated, two dissipated, but what about ten, twenty, fifty?

"Serpent Breathing - Fourth Form: Twin-Headed Reptile!"

"Beast Breathing..."

"Thunder Breathing..."

Obanai, Inosuke, and Zenitsu all raised their swords to help block the attack.

But there were just too many shockwaves, and the people were too close together.

With each 'bang' sound, shockwaves struck the group.

On the other side, Tanjiro retreated while using the Transparent World to dodge the shockwaves through the gaps. Only when he couldn't dodge them did he swing his sword to fight back. For a time, he was in better shape than the others on the other side.

A moment later, everyone finally retreated to a relatively safe area, and the shockwave gradually subsided.

"Cough cough..."

Zenitsu coughed twice, took a breath, and then slowly raised his head, looking ahead with a sense of despair.

There, Akaza twisted his newly grown head and said:

"Ah! Ever since I discovered that Lord Muzan, Kokushibo, and Teiichi all have attack techniques that don't require moving, I've also improved my final form, Blue Silver Chaotic Remnant Light!"

"Originally, after it was developed, I felt it was useless because it was too physically demanding, but now it seems..."

Akaza looked at the group, a smile spreading across his face.

"Sometimes, this kind of move can be quite useful!"

Another location in Infinity Castle.

Clang! Clang! Clang! Clang!...

The sound of intense metal clashing echoed continuously.

The dark red figure remained stationary, while a cyan figure continued to crash into him.

The two exchanged blows quickly, and as the cyan figure retreated and the dark red figure tried to give chase, another pale green figure would rush up and entangle that figure.

Clang! Clang!

Sanemi Shinazugawa raised his sword to block two blows, but was then sent flying by Kokushibo's attack once again.

His feet touched the ground, and he dragged himself along the ground for more than ten meters before his figure slowly came to a stop.

He steadied himself, raised his head, and stared intently at the figure of Kokushibo.

"Unforgivable, absolutely... unforgivable!!"

Sanemi gritted his teeth and spoke each word carefully; he still couldn't forget what had just happened.

Clearly... clearly, I and Genya only made up not long ago...

"Hateful!!!"

Sanemi roared, ignoring his physical discomfort, and charged forward once more.

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

The Wind Blade slashed straight down.

Kokushibo frowned slightly as he watched Muichiro prepare to retreat once again, then raised his sword to meet him on the other side.

Muichiro retreated to a distance of more than ten meters to ensure that he could provide reinforcements at any time.

His hands, hidden beneath his wide sleeves, twitched slightly, easing the discomfort caused by the disparity in strength between them. His gaze remained calm as he watched Sanemi towards Kokushibo once again.

At least I was able to control my fight against Upper Rank One before!

Now, to prevent Upper Rank One from chasing Shinazugawa, they have no choice but to keep going up.

It's as if I'm here all by myself!

Shinazugawa's actions are truly irrational!

Thinking of this, Muichiro slashed at the body that had been cut in half to the side.

Is it because of this person?

The person who just called him "Big Brother"—is he the younger brother of Shinazugawa that Master mentioned before?

Muichiro turned to look at the two combatants and saw that Shinazugawa was about to give up. He moved his feet and charged forward again.

Repeat this process twice.

Clang! Clang! Clang! Clang!...

The dark red blade slashed down, leaving afterimages in its wake.

Sanemi struggled to keep swinging his sword to defend himself.

Blinded by rage, he didn't realize that this time he had held out longer than ever before.

Even if they discover it, they might just assume it's because they were brave and daring.

But Muichiro was on the periphery, keenly noticed the problem, and he frowned.

Upper Rank One's attacks seem weaker?

Is he worried that he might Shinazugawa flying like before, only to get entangled with him again and be constantly worn down?

What should I do then?

Soon, Kokushibo helped him make a choice.

Sizzle! Sizzle!

The blade cut through the gap in the Nichirin Blade, slicing through Sanemi's body twice.

However, this seemed to ignite Sanemi's fighting spirit, and he swung his Nichirin Blade even faster.

Seeing this, Muichiro didn't have time to think about anything else. He pushed off the ground and rushed over quickly.

With two clanging strikes, feeling the immense force transmitted from the Nichirin Blade, Muichiro's brows furrowed slightly.

He glanced in the direction of the Shinazugawa, but said nothing.

Clang! Clang! Clang! Clang!...

The three figures crisscrossed the battlefield.

At one point, Kanao also came to the rescue.

However, even though Kanao's current strength has reached or even surpassed that of the previous Pillars, she still appeared somewhat powerless in her battle against Upper Rank One.

Time flowed by, little by little.

Sanemi's body gradually accumulated more wounds, Muichiro's arms gradually became numb, and Kanao combined the characteristics of both of them, having both wounds on her body and numbness in her arms.

If this continues, will they all be killed?... A sudden realization dawned on Muichiro's mind.

At that moment, a clear, crisp sound suddenly rang out.

"Flower Breathing - Sixth Form: Whirling Peach!"

Taking advantage of a gap in Kokushibo's attack, Kanon leaped out from behind Kokushibo, her Nichirin Blade slashing straight at Kokushibo's neck.

Clang!

The Nichirin Blade didn't break the skin!

Suddenly, his neck was subjected to force, Kokushibo's body tilted slightly. At that moment, only one big question remained in his mind.

Where did this person come from?
