"Boom——"

When the Magic Power erupted like a volcano in the sky, blowing away the clouds and dyeing the dusk dark, the roar of the Polluted Dragon, betting everything, finally vented violently towards the boy wielding the black blade.

"Pierce through! Alondate!"

The newly reborn Fairy Sword Alondate had transformed into Melusine’s claw, into Melusine’s spear, gathering unexpectedly dazzling light under her roar, forcefully thrown in Reiger’s direction.

This strike, in terms of power and speed, far exceeded the state when Melusine previously unleashing her Noble Phantasm.

It was no longer a white comet, but a light cannon capable of destroying everything.

"Hmm?"

Reiger originally intended to rely on the invincibility of [Infinity Curse] to take Melusine’s attack head-on, but a twinge of warning in his heart made him raise his eyebrows and decisively abandon the idea of a direct clash, opting to evade instead.

"Boom——"

The Light Spear brushing past Reiger’s body exploded with a tremendous force, its dazzling light piercing through Reiger’s invincibility, unexpectedly hitting Reiger.

Suddenly, Reiger’s figure retreated violently, as if plowing a trench in an invisible floor, sliding rapidly backward in midair, raising a turbulent air wave.

"Finally hit you!"

Melusine extended her hand to catch the returning Alondate, and a naive smile appeared on her young face, which seemed wickedly darkened.

However, Melusine then raised the black spear again, throwing it out forcefully. 𝙧𝙚𝙚𝔀𝒆𝓫𝓷𝙤𝓿𝒆𝙡.𝒄𝙤𝓶

"Boom——"

The spear, flying out like a missile, gathered impressive light once more, transforming into a light cannon with an astounding momentum, roaring towards Reiger.

"Crash——"

Still sliding backward, Reiger’s eyes flashed with transparent radiance as he watched the incoming Light Spear, raising the black blade in his hand, which immediately sparked with black-red electricity.

"Boom!"

The black blade capable of severing space collided heavily with the approaching Light Spear, instantly unleashing terrifying power, the shockwaves resembling a category thirteen typhoon, sweeping in all directions.

Momentarily, an unusual phenomenon occurred between the black blade and the Light Spear.

On the black blade, where the black sparks passed, space shattered inch by inch, countless space fragments were ground into particles, forming a particle stream, erupting in the sky.

Surprisingly, the light shone from Melusine’s thrown spear quickly repaired the broken space, restoring it to its original state.

Under this light’s impact, Reiger’s foolproof [Dimensional Slash] returned void for once.

"Boom——"

At that moment, another roar erupted.

No, it was not a roar, but rather a familiar sonic boom.

Melusine unfurled her inorganic black wings, stirring the airwaves, carrying the sonic boom, and shot towards Reiger.

At this moment, she seemed as if shedding a layer of restraints, casting off invisible shackles, relying solely on her wings to fly at an astonishing speed.

"Clang!"

Reiger raised his blade to block it, the black Alondate slammed heavily against his blade.

The force erupted from the clash had a vast difference compared to before, so much so that Reiger’s feet stepped repeatedly in mid-air, retreating a significant distance before dispelling the power.

"Boom——"

"Boom——"

Melusine did not pursue, instead grasping her twin spears, transforming into a freely soaring black dragon in the sky, her wings constantly stirring up sonic booms, making her figure inexplicably appear like a fighter jet.

Each of her flights triggered a violent sonic boom.

Her flight trajectory was not linear either, but revolved around Reiger, circling and lingering like a satellite.

Then, every time she reached an ideal point for artillery bombardment, Melusine would immediately throw the spear in her hand, which always gathered dazzling light. Even if Reiger calmly responded, dodged in time, the light erupted during passing would penetrate his invincibility, impacting him.

If not for Reiger’s current "Endurance" parameter being frighteningly high, and his ability to consistently dodge the direct impact of the light burst precisely, he might have been injured by now.

"This power..."

Reiger silently felt the power impacting him, his transparent eyes continuously turning, firmly locking onto the rapidly flying Melusine.

Having reclaimed her true name, reverting to her original form, Melusine now exuded a dragon’s aura that fairies could not possess with every movement, her current form no longer calling for the term ’fairy’ but identical to the strongest entity of the term "Dragon".

Through meticulous observation of the world, Reiger could clearly perceive that in her current state, Melusine’s heart had transformed into the so-called Dragon Furnace Heart, the erupting Magic Power metamorphosing into tangible light.

Enhanced by this light, Melusine’s spears, contrary to their cold weapon appearance, seemed akin to a wide-range destructive weapon like a turret.

Her every throw not only unleashed terrifyingly powerful forces but gradually suppressed the invincibility of [Infinity Curse], finally able to reach Reiger’s body.

"Is it because of her unique nature?"

In the legends of England, Albion is also considered the guardian of the horizon and boundary dragon believed to be the gate to an alternate world.

Therefore, as a being born on the left claw of Albion, Melusine’s original duty is to guard the "boundary" itself.

Although neither in the human history nor in the imaginary realm did Albion ever manage to return to the stars, resulting in a tragic ending, Melusine nonetheless retains the power to manipulate the horizon and boundary, embodying this legendary tale.

Thus, the light bursting from her Dragon Furnace Heart can be seen as a rainbow crossing boundaries, or a key to opening the door to another world, another dimension.

In the face of such power, even the invincible domain of the Unlimited Sorcery Technique would be interfered with.

That power can cross boundaries, even alternate worlds, let alone merely cross a space controlled by a technique.

It is precisely for this reason that Melusine is able to break through Reiger’s invincible domain, genuinely causing him harm.

"Very good."

Reiger did not feel heavy-hearted because of this; instead, he smiled happily.

Just as he said, for him now, only those who can break through the invincible domain of the Unlimited Sorcery Technique are qualified to be his opponents.

Otherwise, no matter how strong the opponent is, if they cannot touch him or cause him harm, then defeating him is utterly out of the question.

Much like Gojo Satoru, who considers himself unrivaled, never regards those unable to penetrate his invincible domain as opponents.

Those who genuinely pose a threat to him are all capable of breaching the invincible domain.

To deal with Reiger and Gojo Satoru, a basic condition one must meet is the ability to disregard the invincible domain.

Only by being able to do this can one be considered their opponent.

"Since you’ve shown enough power, I should return the gesture,"

Reiger swiftly retreated like the wind, suddenly reaching his empty hand toward Melusine soaring in the sky.

"......!"

As Melusine was catching her returning spear, ready to continue searching for a projection point to launch an "explosive attack" at Reiger, her expression suddenly changed, and her figure abruptly halted.

An astonishing gravity force acted on her, pulling her fiercely towards Reiger’s direction.

"What?"

Although startled, Melusine did not struggle; instead, she used the gravitational pull to swiftly approach Reiger, raising Alondate high as she arrived to slash at him.

But still maintaining his backward flight, Reiger changed his palm into a seal, his index and middle fingers together, manipulating the gravity with a sideward wave.

The direction of the gravity acting on Melusine abruptly changed, shifting from towards Reiger to the side.

Thus, Melusine’s strike missed.

Because she was dragged by gravity in the direction Reiger pointed, her figure completely lost balance.

"You have such an ability...?!

Melusine began to desperately resist the force acting on her, her dragon wings beating furiously, causing the atmosphere to explode repeatedly.

"This is just the beginning,"

Reiger grinned at Melusine.

"Whether you’ll see all my capabilities depends on your next performance."

Saying this, Reiger changed his hand seal, then pointed upward.

"Swoosh!"

As Melusine was resisting the gravity, she was forcibly pulled upward, shooting into the sky.

"Jutsushiki hanten Aka."

Between Reiger’s upward-pointing index and middle fingers, a red light symbolizing repulsion began to gather, transforming into a pinpoint of light that shot out violently.

The seemingly small supernova-like Aka pierced through the air, hitting Melusine, who was being dragged by gravity, shooting her into the sky.

"Boom!!!"

The red pinpoint of light, seemingly glass marble-sized, exploded as if a missile had struck its target when it hit Melusine, erupting in a colossal explosion.

"Guh...!"

Melusine, like a fighter jet hit by a missile, shrouded in rolling black smoke, plummeted from high above, resembling a downed aircraft.

"Swoosh!"

Reiger’s figure instantly appeared before Melusine, his empty hand again formed a seal turning into a fist, shimmering with fierce black sparks.

"Black Flash!"

The strike carrying black sparks hit Melusine heavily, smashing her down to the ground completely.
