Demon Slayer: The Naruto Hashira is a pure villain!

Doma looked down at his arm; his skin was gradually turning bluish-purple.

It's poison.

The short female swordsman had her blade coated with wisteria poison.

"That's really going too far... to resort to such underhanded tactics." Douma chuckled, but he could no longer muster enough Blood Demon Art.

Logically, a demon poisoned by wisteria should be in great pain, but Doma, who was fighting and reminiscing about Kotoha, was completely unaware that he had been poisoned.

Or perhaps, Doma feels this pain every time he thinks of Kotoha.

"You and your mother really look alike."

Knowing he was about to die, Doma faced Inosuke and left behind his last words.

Kyojuro seized this opening, his blade wreathed in raging flames, and slashed down fiercely.

"Breath of Flames - Final Form - Purgatory!"

Doma's head fell to the ground with a thud, and before the smile on his face could fade, he was completely silent.

Having lost two Upper Moon demons in succession, Muzan's rage nearly engulfed the Infinity Castle.

He forcibly suppressed his anger and turned his gaze toward the kendo dojo.

He breathed a slight sigh of relief when he saw Kokushibo and Tamamo-no-Mae standing side by side, with more than a dozen Demon Slayer Corps members lying at their feet.

Fortunately, there are still two that are usable.

Although Tamamo-no-Mae has a terrible personality and is as annoying as Doma, her professional skills are truly outstanding.

He can tolerate this bad temper.

"Kill all those Demon Slayer Corps bastards at all costs!"

"Okay, Master Muzan~"

Only Tamamo-no-Mae responded to him, her tone lazy and irritating.

In the kendo dojo, sword energy crisscrossed.

Upon hearing Muzan's order, Kokushibo turned to leave.

Akaza and Doma are both dead. If this drags on any longer, the situation will become even more passive. He must go out and deal with the swordsmen who have broken in.

"stop."

Yayoi drew her sword and blocked Kokushibo's path.

"Tamamo-no-Mae, do you know what you're doing?" Kokushibo's eyes were full of impatience. "Now is not the time for you to act out."

"I wasn't being temperamental."

Yayoi smiled and slowly drew her Nichirin Blade, the blade gleaming coldly. "I'm going to have a bloody battle with you, Master."

"Nonsense!" Kokushibo's face darkened. "What time is it now? Why are you telling me this?"

He tried to bypass Yayoi and leave, but Yayoi didn't move, and the blade was pointed directly at his throat.

"I'm not joking."

"You will not leave here before you kill me."

He spoke honorifics all the time, but Yayoi could not see a trace of respect in his eyes.

"You really think I won't kill you?" The air pressure around Kokushibo suddenly dropped.

Just as the two were about to clash, the sound of a pipa rang out.

Several figures appeared out of thin air at the other end of the dojo.

Sanemi, Muichiro, and Kaigaku were all supposed to "die" at the hands of Tamamo-no-Mae.

The three men simultaneously drew their swords, the blades all pointing at Kokushibo.

Kokushibo's face darkened completely.

"Tamamo-no-Mae! I need an explanation!"

"What's there to explain? He's not dead, so he's not dead."

Yayoi shrugged, casually tossed the scabbard aside, and assumed a fighting stance.

"You've been lying to me all along?!" Kokushibo's voice was filled with overwhelming rage.

“You can’t say that.” Yayoi shook her finger, her smile smug and irritating. “You were the one who lied to me first.”

"I am not Tamamo-no-Mae."

“I am Yayoi Kuwashima, and I am your father.”

"Wow."

Hei Shimou was furious and wanted to curse, but he didn't know how.

"Since you insist on courting death, then I will grant your wish."

"Breath of the Moon - First Form - Dark Moon - Evening Palace!"

Countless crescent-shaped blades of wind swept towards the four of them.

"Breathing of Thunder - Fourth Form: Far Thunder!"

"Wind Breathing - Third Form: Sunny Breeze Tree!"

"Breath of Mist, Second Form: Yae Mist!"

The four figures acted simultaneously.

Lightning, wind blades, and rosy shadows intertwined and collided fiercely with the moon blade.

The clanging of metal reverberated throughout the entire temple grounds.

Sanemi and Muichiro quickly acquired numerous wounds, large and small, their uniforms soaked in blood.

But Shimi didn't even flinch. Instead of using breathing techniques to stop the bleeding, she deliberately deepened the wound on her arm.

The sweet, metallic scent of rare blood instantly filled the entire dojo.

"You bastard, you accidentally shot friendly fire!"

Between attacks, Yayoi wiped the corner of her mouth, suppressed the urge to pounce and bite, and laughed and scolded.

"Sorry." Sanemi smiled at Yayoi, panting. "I'll make sure you're satisfied after tonight."

"You're shameless for saying dirty jokes at a time like this." Yayoi rolled her eyes and casually blocked a crescent blade that was thrust at her from the side for Sanemi.

"It's alright, one of them doesn't understand and the other is too scared to listen."

Kaigaku, who was listening nearby, couldn't stop his mouth from twitching.

What kind of time is this to be flirting with these two!

Have you no shame?!

Taking advantage of Zenitsu's absence, Kaigaku launched into a tirade of sarcastic remarks.

Kokushibo is indeed strong.

That's ridiculously strong.

He had seen every possible attack method and every possible coordinated move the four could think of in his hundreds of years of swordsmanship.

Dismantle, counterattack, and suppress—the movements were fluid and seamless, leaving no room for error.

After a half-hour battle, neither side could gain the upper hand.

Fortunately, Yayoi's Blood Demon Art and Sanemi's rare blood kept interfering, causing Kokushibo's movements to pause very slightly.

Every time Kaigaku or Muichiro was about to be struck, either Yayoi would rush in to block the blow or she would speak up to interfere, and they would always manage to avoid it.

Yayoi, who had taken the blow, suffered one wound after another, yet they healed rapidly at a speed visible to the naked eye.

Aside from the pain, there was nothing wrong.

After a prolonged and unsuccessful attack, Kokushibo's patience gradually wore thin.

He took a deep breath, preparing to unleash an even stronger attack.

Just then—

A lightning bolt struck suddenly from the side and behind!

It was so fast that only a blur remained.

"Thunder Breathing - First Form: Thunderclap Flash!"

With one hand gripping the crimson Nichirin Blade tightly, Ichiro used the extreme speed of Thunder Breathing to force his way into Kokushibo's blind spot, the blade piercing straight through his waist and abdomen!

"what?!"

While Kokushibo was looking down, Muichiro, who was facing him, seized the opportunity.

The boy gripped the sword with both hands, the crimson blade gleaming with a dazzling red light, and plunged it fiercely into Kokushibo's chest.

Attacked from both sides, two crimson blades simultaneously pinned down Kokushibo's body.

Not letting the opportunity created by the two children slip by, Yayoi gripped the hilt of the sword tightly with both hands, channeling all her strength into the blade. The blade gradually glowed with a crimson light, and she forcefully wielded the Crimson Blade!

The crimson blade slashed towards Kokushibo's neck.

"Oh."

Kokushibo suddenly let out a cold laugh.

"This knife of yours is a derivative of my Blood Demon Art."

"You actually want to use it to cut my neck?"

"ridiculous."

With a thought, he was about to unleash the Blood Demon Art to dissolve the knife in Yayoi's hand.

The knife remained completely still.

It did not dissipate, nor did it collapse.

The scorching heat of the crimson blade struck his neck squarely.
