Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 102 The Roar of Hell Opening

Moonlight shone into the bedroom.

Kagaya Ubuyashiki lay there quietly, with only his wife kneeling beside him.

In the eyes of Muzan, a monster who has lived for thousands of years, Kagaya Ubuyashiki is now like a broken lantern that could be extinguished at any moment.

"You're so arrogant and ignorant, ruining my plans for a thousand years." Muzan's tone was icy, and he didn't feel as furious as he had expected.

Perhaps seeing that the head of the Ubuyashiki clan had fallen to such a state, he felt it was not worth getting angry with a dying man.

Perhaps it's because the millennia-old feud is finally coming to an end tonight, and I've entered a state of sagehood.

"Ubuyashiki, you're even starting to smell like a corpse; you look like you're about to rot completely."

"Heh...of course..." Kagaya forced himself to sit up, his festering wounds tearing open with his movement, blood seeping from the bandages. "After all, half a year ago...the doctor said I was going to die...I've held on until today...all because I wanted to see you die, Muzan..."

"This is ridiculous. You're the one who's going to die, not me."

'

...If I kill you...the curse of the Ubuyashiki clan...can finally end...?

"I understand less and less what you're saying. What does your curse have to do with me?"

"It is precisely because...because of a monster like you...that our Ubuyashiki family...has been dying out generation after generation."

The family has been plagued by illness for generations... the only way to neutralize the curse is through the bloodline of the priests...

'

Kagaya Ubuyashiki was out of breath and spoke in broken sentences, which made Muzan frown deeply.

He looked impatiently at Kagaya's dying, rotting body, pointed to his head, and said, not knowing if the other could see it: "Nonsense, disgusting."

"Can your illness also infect the brain?"

"What you're saying has absolutely no causal relationship."

Muzan sighed. This was probably the first time in a thousand years that he had heard such an absurd accusation: "There are no gods or Buddhas in this world, so where does this divine punishment and curse come from?"

"Even if I killed hundreds or thousands of people, I never faced any punishment. Doesn't that prove you're talking nonsense?"

He watched silently as the head of the Ubuyashiki clan coughed up blood incessantly, feeling a profound emptiness in his heart.

It's so strange. We could have ended it all by now. The repulsive leader of the Demon Slayer Corps is right in front of us.

I felt nothing at all.

"Heh—Muzan, you don't know, do you—there are gods in this world—"

"Speaking of which... your dream is eternal, isn't it..."

'

"It's a pity... this dream has to end today... true immortality is not in the physical body, but in the continuation of the spirit..."

"Once you die... all the ghosts will die, right..."

'

What?

Muzan snapped out of his daze and saw Kagaya Ubuyashiki wearing a smug smile.

And the dazzling, blazing firelight rising from beneath his feet...

"Gah!! Gah!! Emergency! Emergency!"

The mournful cawing of crows instantly shattered the solemnity of the night.

Dozens of crows seemed to have been prepared, rushing swiftly to various training grounds, forest paths, and the Pillars' usual routes.

Their voices were hoarse and shrill, filled with unprecedented terror: "Headquarters under attack! Muzan Kibutsuji has appeared! All Pillars, assemble immediately! Head to the Ubuyashiki mansion at once!"

"Encircle them! Encircle them at full speed!"

Has it finally arrived?

The bird's silhouette flashed across the land, its gray-white feathers fluttering in the gale.

His speed was extremely fast, and with each step he took, his toes were accompanied by subtle bursts of spiritual pressure.

He transformed into a black lightning bolt, frantically weaving through the dense forest and jumble of rocks.

In the distance, several powerful auras were also converging on the same core at the same frantic speed.

"That bastard Muzan! He's finally here!" Shinazugawa Sanemi's roar echoed through the forest.

His mind was still replaying the plan to lure the enemy with false information, which Kiriya had described at the meeting earlier.

"My lord, you absolutely cannot be harmed... As long as we successfully encircle him, that bastard will definitely not escape!"

On the other side, Giyu Tomioka remained silent, like a withered tree, but his deep blue eyes shone with an unprecedented fervor.

He gripped the hilt of the knife tightly, his breathing rate adjusted to its limit, a state of resolute readiness to activate the markings and overdraw his life force at any moment.

Gyomei Himejima, Kyojuro Rengoku, Obanai Iguro, Mitsuri Kanroji, Muichiro Tokito... all the Pillar-level swordsmen capable of fighting, at this moment, summoned by the cry of a crow, cast aside all distractions and rushed towards the mansion.

Their motivations and experiences differed, some driven by revenge, others by a desire to protect, and still others by a mission that had endured for millennia.

But at this same moment, they had only one goal:

Slay the Demon King!

Just as the pillars were less than two hundred meters from the mansion, and the outline of the outer walls could be vaguely seen, a deafening rumble echoed—!!

A golden orb of destructive light suddenly erupted from the core of the mansion!

That was a violent explosion powerful enough to shake the entire valley!

The bird that was at the forefront was forced to stop and put its arms in front of it.

A wave of heat hit him, and he felt like his skin was being burned.

Before the horrified eyes of all the Pillars, the Ubuyashiki mansion, which had been the core of the Demon Slayer Corps for a century and was filled with the fragrance of wisteria, was reduced to dust in an instant!

Flames shot into the sky, illuminating half of the night sky.

"No! My lord!!"

Kanroji Mitsuri let out a mournful cry, stumbled, and nearly fell.

At that moment, the presence of Kagaya Ubuyashiki, along with his wife Amane and their two children, Hina and Hinatsu, who had always been by his side, completely vanished from the world of the living.

As a sacrifice to open the gates of hell.

That man used his own flesh and blood, the lives of his family, and this sense of mission that has lasted for thousands of years.

He personally detonated the massive amount of explosives buried under the tatami mats, all to deliver a devastating blow to Muzan on this fateful night of ending!

Amidst the sea of ​​fire, smoke and dust filled the air.

"Cough... Ah... Damn it!! Ubuyashiki—!!!"

A distorted, hoarse voice, filled with extreme anger, came from the center of the ruins.

Muzan's once elegant human body was now a gruesome sight.

Half of his head was blown off, all four limbs were severed, and the newly formed flesh buds writhed wildly like maggots in the firelight.

To his surprise, the explosives seemed to have been mixed with countless specially made barbed wire spikes and wisteria poison.

These tiny foreign objects invaded Muzan's blood vessels at the moment of the explosion, greatly slowing down his regeneration.

He had considered that Ubuyashiki might set a trap, but he never expected him to go this far!

"Wait... these toxins are meant to slow my regeneration... He knows he can't kill me? He has a backup plan!"

"He actually used his own life and his family's lives as bait... Did his family know? Did they know and still play along?"

"To be able to conceal such intense killing intent at such a young age, I didn't even notice! What a family of insidious bastards!!"

No, calm down, now is not the time to think about these things.

"Muzan—!! You've finally met your match!!"

A woman's voice suddenly rang out from the shadows of the rubble.

It's Tamayo!

That was a female demon who was once Muzan Kibutsuji's close attendant, but escaped his control and has been searching for a way to fight him for hundreds of years!

I can't believe that bastard Ubuyashiki actually collaborated with that bitch!

Using the aftershocks of the explosion and her Blood Demon Art to conceal herself, she got close to Muzan and plunged her fist into his writhing abdomen.

"This is the medicine that turns demons back into humans!" Tamayo's face appeared exceptionally resolute in the firelight, her once elegant and noble features now twisted into a monstrous demonic grin: "For this moment... I've waited four hundred years! Muzan, come to hell with me!!"
