"Boom!"
A heavy burst of air exploded just before the prison barrier, causing the Valkyrie, engulfed in rainbow-colored flames, to unleash a terrifying magical storm.
"What... what is that...!?"
The ancient city was almost blown away by the sudden magical storm. Hastily, it raised its arms to block the powerful winds and lowered its body to stabilize its stance, barely avoiding being swept away. However, it was still shocked by the appearance of the Valkyrie from behind No. 6.
"That's the beast vassal of No. 6..."
Even Rozen couldn't help but raise a hand in front of himself, watching the majestic Valkyrie. He felt the blood within him boiling, resonating with the beasts connected to the Valkyrie.
No. 6, summoning its beast vassal, released its maximum magical power while its voice echoed loudly.
"To lift the seal of the prison barrier, one needs both exceptional spatial manipulation techniques and immense magical power surpassing the ley lines. Both are indispensable. Even though the prison barrier has already manifested, breaking it and entering requires an attack with magical power surpassing the ley lines."
After all, the prison barrier was constructed using the ley lines flowing through Itogami Island. Without magical power surpassing the dragon veins, how could it be broken?
However, under normal circumstances, it would be impossible for an individual to meet such conditions.
Even the three Primogenitors might not possess magical power surpassing the ley lines; at most, they could match the ley lines. Only the magical power of the Fourth Primogenitor, known as the strongest vampire in the world, could meet this requirement.
Therefore, to lift the seal of the prison barrier, LCO originally planned to sacrifice the citizens of Itogami Island, using the lives of a hundred thousand people to forcibly break the seal.
But now, with the assistance of No. 6, there was no need for such trouble.
"My beast vassal is the Valkyrie of Severance, governing the severance of authority. It can sever all physical forms and their causality with a single stroke."
No. 6 spoke as if introducing its abilities to someone.
"In front of my beast vassal, Minelauva Iris, even the seal of the prison barrier cannot escape being severed."
With that, the Valkyrie behind No. 6 turned around.
"Stop... stop it...!"
Avrora, held by No. 6, immediately shouted.
But No. 6 ignored her pleas, controlling its beast vassal to raise the light sword in the Valkyrie's hand high and fiercely sweep it down.
Suddenly, there was a burst of air and magical power, as the Valkyrie's strike, capable of severing even causality, swept towards the direction of the prison barrier.
The next moment...
"In the dimness, the cloud flickers and sways, the flickering fate, the intense fate, the pouring force, the swaying moment, observe-style formation, violently swaying, interrupted in the flicker..."
A voice chanted a solemn spell at an astonishing speed.
In that instant, an invisible and terrifying impact pierced through space, crashing into the Valkyrie preparing to attack the prison barrier.
"Boom!"
Accompanied by a frightening explosion, the Valkyrie's strike did not land smoothly. Instead, it was blasted back by the sudden and terrifying impact, stirring up a pair of flaming wings and retreating violently for quite a distance, stabilizing its stance only when it soared into the air.
"Do you think I'll let you?"
Rozen stared at No. 6 with cold eyes, maintaining his clapping posture as his magical power transformed into blood mist.
Within the blood mist, countless silver-white chains appeared like agile dragons.
It was the magical tool, the "Lawbinding Shackles," which had already formed an absolute contract with Rozen, transformed into beast vassals, and fused with ten Valkyries. Now, it was a fully-fledged living weapon - the "Injunction Shackles."
The chains, like living beings endowed with the will of ten Valkyries, had completely transformed into weapons capable of automatic restraint, attack, and defense. With just a thought from Rozen, they would all turn into agile dragons and surge towards the direction of the enemy.
And at this moment, the chains were aimed at the Flaming Valkyrie in the air.
As the Valkyrie had not yet reacted, the agile chains swiftly entwined around her, tightly binding her and suspending her in mid-air.
"Is that also your beast vassal?"
No. 6 looked at this scene, her eyes burning with flames, slightly stirred by the sight of the chains.
"No, that should be the magical tool of the Witch of the Void."
Tokoyogi Yuuma seemed to have been instilled with knowledge about that moon, staring at the chains with a slightly changed expression.
"What exactly is that, a Beast Vassal or a Magical Tool?"
"LCO hasn't given us any information about this!"
Even the Meyer sisters couldn't help but exclaim.
Only Kojou and Avrora couldn't help but show a pleased expression.
Rozen's body was trembling with magic, and his voice sounded extremely cold.
"—————"
Rozen quietly chanted a spell.
It was the immovable king's subjugation method————the Fire Realm Incantation.
The surging flames were immediately awakened and turned into raging flames, sweeping through.
The flames, like a storm, surged towards No. 6 and Tokoyogi Yuuma's group.
"...!"
Tokoyogi Yuuma immediately reacted, grabbing No. 6, and together with No. 12, using Space Manipulation Magic, they instantly merged into space, avoiding the oncoming waves of fire and appearing in the sky instead.
But as Tokoyogi Yuuma and the others evaded, the Meyer sisters immediately faced the raging flames.
"No... no!"
"Guardian...!"
Seeing Rozen release the flames, the psychological trauma in the Meyer sisters' hearts was immediately awakened, causing them to scream simultaneously and summon countless tentacles, layer by layer in front of them, to block the oncoming flames.
But this was just the beginning.
"——————"
Rozen immediately continued to chant the spell without hesitation.
This time it was the technique of Indra's Water Heaven————the Water Heaven Technique.
The awakened vast water vapor formed into huge waves around Rozen, rushing towards Tokoyogi Yuuma's group in the sky.
"〈Le Bleu〉!"
Facing the surging torrent, Tokoyogi Yuuma shouted loudly.
"Hum!"
The next moment, a knight emitting a ominous aura, with his body showing a blue color, appeared in front of Tokoyogi Yuuma.
It was Tokoyogi Yuuma's guardian————〈Le Bleu〉.
The guardian named 〈Le Bleu〉 raised his great sword high and swung it towards the oncoming waves, not shaking the atmosphere, but shaking the space.
"Boom————!"
The collision of the surging torrent and the shaking space caused a thunderous roar.
The roar was like an explosion, spreading through the air.
Endlessly.
