Editing Seirei Tsukai no Blade Dance:Volume19 Chapter11 (section)

===Part 1===

The top-tier wide-area destructive magic of the darkness element.

The jet-black magic lightning released by the Demon King kept destroying buildings in the town.

The ground was punctured and left with countless craters.

"...Damn it... Are you okay, Claire!?"

"Y-Yes... Why is this so crazy...?"

Kamito and Claire crawled out from the collapsed debris.

Were it not for the Vorpal Sword, whose darkness element allowed it to act as a lightning rod to absorb the magic lightning, the two of them would likely have been scorched to ash in an instant.

Although Hell Blast was also a type of spirit magic that Restia used&mdash;

The firepower demonstrated here far surpassed what the top-tier spirit could use.

"...Living up to his name as the most powerful elementalist in history, the real Demon King himself."

Muttering, Kamito wiped fresh blood off a corner of his lip. The amount of divine power was extraordinary.

"How do we handle that monster...?"

"Just go all out and take a gamble. The enemy looks all fired up."

Kamito poured divine power into his two swords and stood up.

(...Est has finished analyzing. At least, there won't be any nullification again.)

The Demon King extended both hands this time. The skull mask glowed with eerie light.

"...!"

Hastily, Kamito and Claire jumped to the sides.

"Eternal... sleep&mdash;Cocytus."

One could hear air freezing.

Shrouded in white mist, everything within a radius centered on the Demon King was frozen&mdash;

From the ground, countless arms of ice reached out for Kamito and Claire.

"Incinerate until nothing remains, O scorching conflagration&mdash;Fireball!"

With the sound of an explosion, Claire chanted flame spirit magic, shattering the generated ice.

However, the endlessly appearing ice covered the flames, surging towards them like a giant wave.

"Absolute Blade Arts, Third Form&mdash;Shadowmoon Waltz, Double Moon Turn!"

With a mighty shout, Kamito released divine power all at once.

Countless black and white flashes of the sword.

Leaving sword afterimages one after another, Kamito rushed in as a whirlwind.

Confronted with ice arms attacking from all directions, he shattered, severed or broke them with his every motion.

Stepping on a giant piece of ice fallen on the ground, he leaped into the air and&mdash;

"Absolute Blade Dance, Second Form, My Style&mdash;Double-Hit Comet!"

A dual-sword move of the Absolute Blade Arts, modified from Comet, was unleashed against the Demon King.

BOOOOOOOM!

The impact of the comet crash shook the air.

Together with the black garment, the Demon King's body was sliced into two. A gigantic crack appeared on the ground.

"...!"

Kamito did not feel the move connect.

He immediately jumped to the side. At the same time, a black blade swept by, just above his head.

(...Shadow spirit magic, huh?)

That magic was Ms. Freya's specialty.

The Demon King lifted a skinny black hand.

The golden ring on his finger instantly glowed ominously blue.

(...That ring is!?)

'&mdash;Kamito, beware. He is about to summon a spirit!'

Restia issued a warning.

That ring was the Ring of Solomon.

A legendary artifact capable of controlling seventy-two archdemon-class spirits.

(The spirit magic earlier was just a welcome greeting, huh?)

A terrifying voice sounded under the Demon King's mask.

"From underground, come... My minion&mdash;Midgardsormr."

Rumble rumble rumble rumble rumble...!

"W-What's going on!?"

Accompanied by a violent earthquake, the land on Ragna Ys split opne.

Appearing out from the crevasse in the shattered and frozen ground&mdash;

A gigantic serpent all covered in countless steel-like scales. Compared to the Holy Kingdom's militarized spirit, Kerykeion, which was also a snake, it was several times larger.

'Earth dragon spirit Midgardsormr. It is the prototype for the strategic-class militarized spirit Jormangand that was sleeping in the mining town of Gado, you know&mdash;'

"...What did you say!?"

The gigantic earth dragon spirit opened its jaws and crushed buildings in the street.

"...Even the Demon King's contracted spirits can materialized?"

'Yes, what the angel summoned are the Demon King's complete powers&mdash;'

To this, Est replied.

"Kamito, I will come up with a way to handle this spirit!"

Claire shouted.

Kamito took a closer look and saw that Flametongue had entangled Midgardsormr's horn.

"Don't overdo it, Claire!

"Don't worry and focus on the Demon King, kyahhhhhhhhhhhh!"

The enraged giant serpent rampaged, causing Claire's petite figure to get thrown around in circles.

The gigantic writhing body swept across the land of Ragna Ys.

(...At this rate, the whole underground will be all dug up!)

Kamito jumped aside, dodging a strike from the tail.

He rushed up the earth dragon's back in one go, pouring all of his divine power into the swords in his hands.

His left eye began to hurt again.

He remembered Rubia's warning to him, but&mdash;

"Absolute Blade Arts, Destructive Form&mdash;Bursting Blossom Spiral Blade Dance, Eighteen Consecutive Strikes!"

Unleashing numerous slashes simultaneously, he destroyed Midgardsormor's scales of steel.

'It's not over, Kamito&mdash;!'

Restia called out.

Midgardsormr raised its head and widened its jaw.

(...! I can't believe it can still move after taking an Absolute Blade Arts move for countering archdemon-class spirits!)

Kamito kicked the ground and jumped, evading the attack, then plunged the jet-black demon sword into the monster's eyeball.

"O darkness, pierce&mdash;Vorpal Blast!"

The magic lightning of darkness erupting from the demon sword's blade shattered Midgardsormr.

However...

"From the ends of the sky, respond to my call... Minion&mdash;Fafnir."

The Demon King's ring glowed and summoned a spirit from thin air.

It was a dragon spirit with jet-black wings.

The dragon's claws attacked from overhead. Kamito blocked the attack with the Demon Slayer.

The heavy attack almost dislocated his shoulder&mdash;

"Absolute Blade Arts, Seventh Form&mdash;Biting Dragon, Double Strike!"

With a back handed strike of his sword, Kamito decapitated the dragon spirit.

"Huff, huff, huff...!"

He panted and pressed his hand against his aching left eye.

(If he keeps summoning archdemon-class spirits...)

"From the dimensional gate, respond to my call... Minion&mdash;Ymir."

"...!

"You wish&mdash;Flame Chain!"

Claire swung Flametongue.

Enveloped in a conflagration, the long whip immobilized the Demon King's right arm.

Instantly, the Demon King's right arm carbonized and turned into ash.

"Kamito, do it now!"

Accompanied by Claire's shout&mdash;

Kamito dashed in one breath, executing a violent slash.

However&mdash;

It was easily deflected.

A jet-black demon sword appeared in the Demon King's hand and blocked the attack.

"What!?"

Kamito was speechless.

The demon sword held in the Demon King's hand was almost like&mdash;

"...I see. Indeed, ''that'' is the strongest spirit employed by the Demon King."

With anger in his voice, Kamito spoke.

Feeing the pain in his left eye, Kamito gripped the Vorpal Sword tightly.

"But, ''that's my sword'', Demon King Solomon!"

Kamito stepped forward and slashed.

The demon sword of darkness clashed violently with the Vorpal Sword.

Ohhhhhhhhhhhhhhhhhh!

The Demon King roared.

It was a howl of joy for encountering a formidable foe.
