Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 238 Follow-up examinations are still necessary after surgery.

Is Metastacia dead?

Dead, yet still alive.

That night, he resided in Haiyan's body, and their souls were already in sync, the two of them infinitely approaching the same existence.

However, Shinobu's arrival disrupted his plans.

The tiny insect, capable of entering the microscopic world, severed the connection between Metastacia and the petrel's souls, forcibly separating them from the very source of death.

His power was devoured and obliterated by the spirit insects, and his consciousness fell into endless darkness.

He didn't know how much time had passed before he could feel the breath of life again.

At first it was just a tiny glimmer of light, and then it became the whole world.

Perhaps a fragment of her own soul had completely merged with Kaien, or perhaps Shinobu Kocho's Zanpakuto ability could not completely eliminate the effects of the parasitic connection.

In short, on a sunny afternoon, Metastacia was resurrected.

But he dared not reveal himself and remained quietly lurking deep within Shiba Kaien's body.

It wasn't until one day, when Kaien tried to tame his Zanpakuto and attempt to train in Bankai, that he finally found his chance.

Taking advantage of the opponent's weakness, he launched another attack and almost managed to take over the body.

Unfortunately, Haiyan not only suppressed his consciousness, but also absorbed the power of the void.

Although Metastascia was extremely angry, he was helpless.

Kaien, who has awakened his Bankai, is a powerful Shinigami with second-class spiritual power, and he is completely unable to resist.

He could only occasionally curse and insult Haiyan with vicious words in his mind, trying to provoke him, but to little avail.

Now, Haiyan has been drawn into this chaotic world, and is finally losing her mind and may even be going crazy!

And he was finally able to see the light of day again, slowly separating from his body!

The berserker's body began to contort, and shadowy tentacles of whiskers emerged from beneath his Death Armor.

A crack appeared in the bone mask, revealing crimson tentacles wriggling inside.

Metastasia realized that Master Kariya Matou's magical energy was about to run out.

The flame of life flickered precariously, and the supply of magic was intermittent.

If this continues, Yan Ye will be drained dry and become a dried-up corpse.

Once Kariya dies, or his magic is completely cut off, the spirit of Berserker Shiba Kaien, as a Servant, will slowly disappear.

Haiyan is a pseudo-follower who doesn't belong to this world. Where will his soul go?

Will Metastasia, who is parasitic in Haiyan's body, be able to enter the spacetime rift with him as before?

He was unsure and dared not gamble.

"...I haven't become a Vasto Lorde yet! I haven't stood at the pinnacle of Hueco Mundo!"

[He finally recovered, how could he die here!]

His gaze, through the shattered mask, was fixed on the man radiating golden light.

As long as it can parasitize that body...

You can then become the king of this world!

But how can we get close? The enemy's firepower is too intense; the attacks from that treasure vault behind them are endless, making it impossible to get close.

We must find a way to create a weakness... We must... gamble with our lives!

In order to prolong his existence and to fulfill his inner ambitions, he began to fight back desperately!

"roar--!

""

The berserker let out a deep roar, and black energy surged around him.

He opened his mouth, and red energy condensed within it—a sign of a holographic flash.

Gilgamesh, however, was unaware of this, and merely frowned as he looked at the red light: "Still has power left?"

Before the words were even finished, a beam of red light carrying destructive power shot out!

"An anti-personnel weapon? Or magic? Your tricks are really something... huh?"

To Gilgamesh's surprise, the Cero didn't shoot directly at him.

Instead... it split apart.

The thick red beam of light suddenly exploded in mid-air, transforming into hundreds and thousands of tiny red beams that indiscriminately covered the entire space around Gilgamesh like a rain of flowers!

"What?!" Gilgamesh was stunned.

These beams of light are not very powerful; they might not even be able to penetrate one's own armor.

What is the point of this attack?

The King of Heroes waved his hand, ordering the King's Treasure to unleash a powerful weapon to suppress the attack.

Boom boom boom—!

A barrage of holographic beams and Noble Phantasms collided, causing continuous explosions and billowing dust in the sky!

Seeing this, he suddenly understood.

Just as Gilgamesh instinctively tried to disperse the smoke and dust, a dark figure, like a ghost, pierced through the flames of the explosion and appeared in front of him!

It's a berserker!

At this moment, he had completely abandoned his defenses.

He was covered in wounds from the aftershocks of the explosion, with only his left arm remaining intact.

His body was riddled with fragments of Noble Phantasms, and he was covered in blood, looking like a demon crawling out of hell.

But his speed was incredibly fast!

Using the recoil from those Cero explosions, he used his body as a bullet, propelling himself right in front of Gilgamesh!

The distance was less than five meters.

His body flowed like liquid, and the tentacles beneath his mask stretched out, wrapping around the other's spirit.

"Bastard! Get out of here!" Gilgamesh roared, instinctively raising the sword Ea, but the berserker's speed had already reached its limit in that instant.

With Metastacia already disregarding everything, she didn't care what happened to Haiyan's body, and she became even faster and more ruthless!

Finding an opening in the Noble Phantasm's attack, the tentacles suddenly stabbed at Gilgamesh's spirit body's side!

Gilgamesh's body stiffened, and shock flashed in his red eyes.

These barbed tentacles actually carried some kind of toxin that could corrode spirits, instantly corroding a large hole in the golden armor.

There was a wound on his side.

Golden particles splashed out, and for the first time, pain appeared on the King of Heroes' face.

"You...!!"

Before he could react, Metastacia's tentacles had already burrowed into the wound, probing into the spirit like parasites.

He attempted to shatter the tentacles with his Noble Phantasm, but Metastasia had already dissipated into dark currents, and the ethereal power began to spread within Gilgamesh's body...

Hehe, got you!

Metastasia's voice rang directly in Gilgamesh's mind, filled with boundless ecstasy.

"You monster!!" Gilgamesh roared in fury, but then felt a wave of dizziness wash over him.

The golden, glittering King of Heroes began to flicker.

His body shuddered, and he fell from the sky.

Even Tokiomi Tohsaka, who had just defeated Kariya Matou and was preparing a large-scale magic spell in the distance, sensed the unusual movement in the King of Heroes's spiritual core and his expression changed drastically!

"Was it interfered with by berserk magic?! How is that possible?!"

"That's the King of Heroes! The most ancient king with divine powers!"

Tokiomi's shock was not without reason.

Gilgamesh is a legend who transcends ordinary heroic spirits and is the prototype for almost all heroic spirits.

"Its spirit is not a copy of the Throne of Heroes, but rather the spirit itself appeared on its own initiative after being invited by the Grail system."

In other words, his arrival was not a summoning by Heaven's Feel, but rather he was willing to participate in the war in Servant form for fun.

He is a demigod born from the heavenly god Anqi and Queen Ningsong of Uruk, and possesses a natural high resistance to magic, pollution, and magical artifacts.

How could something like this be contaminated again and again?!

If it were a normal Holy Grail War, Tokiomi's shock would be understandable.

The problem is that this war has summoned people who shouldn't exist.

Influenced by the birds, the world responded to Metastacia's wish.

He was not originally capable of breaking through Gilgamesh's defenses, let alone using his rudimentary parasitic methods to interfere with the demigod's core.

The problem is that, in order to find out about the Berserker's condition these past few days, Asuka has had too much contact with him and has become tainted by the aura of karma.

Gilgamesh's body fell into Vimana and was rapidly plunging into the river.
