White-Haired Siblings

Aslant, a world brimming with magic.

Three continents gazed across the oceans at one another, forming the body of this world.

On the eastern continent of Ishgar, in a valley on the border of the Kingdom of Fiore, a battle raged fiercely.

A dark purple magic circle rapidly expanded from the white-haired girl's left hand until it enveloped her entire body.

"Take Over Magic: Satan Soul"

When the magic circle vanished, the girl's demeanor shifted dramatically—her gaze turned icy, and a brutal aura unconsciously radiated from her. Her appearance, like the magic she had unleashed, was as if a Demon Queen had descended in person.

The giant beast, feeling its dignity affronted, let out a roar. The ground beneath its feet cracked under heavy stomps, the surrounding slopes shattered from the roar, and rubble and dead branches tumbled down from the tremors.

Yet this terrifying beast, capable of splitting earth and shattering mountains, was locked in a deadlock with a human girl five times smaller than itself.

Not far away, a burly man and a petite, adorable girl watched the scene tensely. They shared one trait with the girl in the fray: all three had white hair.

The petite girl watched the figure weaving nimbly beneath the giant beast's fists, both nervous and awestruck. "Elfman, big sis is so amazing. She can take on an S-class Beast King all by herself. I heard other guilds need at least two S-class Mages to even have a chance against one."

"Yeah, Lisanna. Big sis Mira is just that strong. If only I had half... no, a third of her courage."

Despite his muscular build, the burly man was genuinely underage. And contrary to his tough-guy appearance, the youth named Elfman had a gentle, somewhat timid personality.

The magic of all three siblings was "Take Over Magic."

The ceiling of this magic was closely tied to the power one took over. This S-class mission to hunt the "Beast King" was taken on by Mira for her brother Elfman's sake.

She hoped her brother could take over the Beast King's power.

The magical fluctuations in the valley grew increasingly violent and oppressive.

The giant beast roared, and the heavy sound waves caused the surrounding cliffs to burst open once more.

Dodging a heavy punch by a hair's breadth, Mira's expression turned grave. The target of this mission was stronger than she had anticipated—truly a task that required at least two S-class Mages working together to have a chance at completion.

The stronger it was, the more it proved the Beast King's potential. If Elfman took over this power, maybe he'd finally show some manliness.

Fighting the Beast King alone was tough, but Mira had no intention of retreating. Her title "Demon" was earned through hard-fought battles.

If she backed down because of some mere beast, that red-haired freak would never let her hear the end of it.

Manipulating darkness—the most basic and core ability of "Satan."

Mira raised a hand and lightly pulled at the void, conjuring a wild torrent of pure dark magic that surged toward the Beast King.

The power of this strike was enough to shatter a boulder.

But to the Beast King, it was nothing more than a ticklish attack, leaving only a faint mark on its hide without any real damage.

As an S-class magical beast, the Beast King couldn't speak human language, but it was no low-intelligence animal. It cast a mocking glance at Mira, brimming with provocation.

Seeing the Beast King tank her magic with its bare flesh, Mira didn't let the taunt get to her. It was just a small spell—plenty of her guildmates could take that hit.

The test of the Beast King's defenses was over.

Now came the real attack.

The Beast King's shadow loomed like a small mountain, its massive fist carrying immense force, enveloping Mira entirely.

Mira's demonic wings snapped open, and she nimbly dodged the ferocious strike, spiraling up along the Beast King's arm to face its terrifying, fanged visage.

Before the giant beast could pull back to defend, Mira unleashed her full power. Two clusters of darkness gathered in her hands, whipping up a chaotic magical vortex that engulfed the Beast King's head.

The air was rapidly compressed and drained, a suffocating pressure crashing down. The Beast King, unable to breathe, was driven by survival instinct to move at an unnatural speed.

The giant beast's hand swept toward her. Mira dodged instinctively, but maintaining the magic vortex slowed her just enough. The massive hand seized her body, gripping her tightly in its palm.

As the Beast King's hand tightened, Mira's bones began to creak. Against the earth-shattering force of the Beast King, the physical resilience granted by "Satan Soul" proved utterly inadequate.

Her body crushed by immense pressure, on the verge of being ground to pulp, the searing pain forced a scream from Mira.

"Ahhh!!!"

This sight filled Lisanna with panic, but her own strength was too low—rushing into the battle would only distract her sister.

"Elfman..."

Lisanna turned around, but her brother Elfman was nowhere to be seen.

Down in the valley, a burly figure lunged with all his might at the beast several times his size—it was Elfman!

His Take Over Magic had yet to absorb any power; for now, Elfman was just a strong minor. Trying to shake the Beast King was a fool's dream.

Elfman knew he was a pebble hurled at a mountain, but he couldn't stand by and watch his sister suffer.

A sting like an ant bite on its calf alerted the Beast King to the man biting its leg. Teeth—that was the only weapon Elfman had that could harm the Beast King.

Though it didn't even break the skin, the Beast King was furious at being bothered by such a weak human.

Flinging Elfman aside, the Beast King raised its massive foot high, about to crush him into paste.

Just then, a fierce gust of wind surged from in front of it. A sharp sense of danger tightened the Beast King's gut. A deadly blade of dark magic formed, slicing through the hand gripping Mira.

"Oww!!"

Clutching its wrist, the Beast King retreated, bewildered that the human it had nearly crushed moments ago could unleash such terrifying power.

"Well done, Elfman."

Forcibly bursting out with magic power only worsened Mira's already severe injuries, but she was happy nonetheless, because her cowardly little brother had finally found the courage to save her.

Even if his blind charge was reckless...

"It's time to end this."

Flapping her wings, she carried Mira into the sky. Gazing down at the howling Beast King without a trace of emotion, a purple-black magic circle appeared once more, covering her entire body.

"Full Takeover: Demon God Halphas!"

Pale blue horns sprouted from her head, her limbs were covered in pale blue scales, and her demon wings transformed into demon god wings of the same hue.

The Satan form faded.

The Demon God manifested!

As the "Demon God," Mira possessed unbelievable speed, and her magic power and destructive force overwhelmingly surpassed that of "Satan Soul."

"This is a power the Master forbade me from using."

"To die by this power is your honor!"

Spreading her pair of wings, Mira stood aloft in the air. Beneath her calm eyes, she released an exceptionally violent surge of power and killing intent.

The Beast King, infamous for his formidable strength and physique, did not retreat even after losing one hand. Instead, it fully ignited his wild nature.

Pushing off the ground with his legs, he leaped into the sky, roaring and swinging a powerful, heavy fist.

This time, Mira did not dodge. Instead, she clenched her fist and met the Beast King head-on in a clash of brute force.

A ring of white air exploded directly in the air, kicking up rolling gales. Elfman, hiding in a corner, poked his head out and saw a scene he would never forget for the rest of his life.

The mighty Beast King now crashed heavily to the ground, vomiting blood in great gushes. The arm that had clashed with Mira's fist was blasted into a bloody mist, and torrents of beast blood sprayed from the stump. His life force dissipated at a visible rate.

One strike had killed the Beast King instantly!

As expected of Mira-nee!

Elfman looked up at Mira with admiration, not noticing the gradually fading golden light in the clouds above.

Mira descended slowly, looking at her younger siblings running towards her. She gave a doting smile, then spat out a mouthful of blood.

The Demon God form dissolved, and Mira collapsed weakly.

"Onee-chan!"

Elfman and Lisanna were horrified at the sight and rushed towards her.

"I'm fine, just some minor injuries. I'll be better after resting a while."

Even though Mira said that, even an ordinary person could see how severe her injuries were.

Not far away, the Beast King gradually stopped breathing.

Mira pushed her brother. "Elfman, go. Go obtain the power that belongs to you."

A look of firm determination surged in Elfman's eyes. His sister had been so badly injured for his sake; he absolutely could not let her down.

Walking towards the still-warm corpse of the giant beast, Elfman struck while the iron was hot, unfolding his magic circle and pulling the Beast King's power towards himself.

"Hngh... Aaaaaaah!"

His strong body was filled with pain. Enduring the excruciating agony in his spirit, Elfman successfully took in the "Beast King Soul." As long as he developed it well in the future, he could also unleash the power the Beast King had in life, and even had the potential to surpass it.

"Onee-chan! I... Ugh!!"

The joy on his face was instantly replaced by ferocity. Before Elfman could finish his happy report, his eyes were filled with brutality, and he let out a pained roar.

The sudden change startled the sisters Mira and Lisanna.

Feeling the look Elfman gave her, Mira thought, This is bad. The one controlling Elfman now was the Beast King who had just died!

Although she had killed the Beast King, Mira had overlooked one thing: how could a giant beast that had given her such a hard time be so easily taken over by her little brother?

Whether in spirit or will, Elfman was far from a match for the Beast King right now.

"Lisanna, run!"

Severely injured, Mira had no strength left to fight. She knew the Beast King's hatred was directed at her, so Lisanna had a chance to escape.

"Hehehehe~"

"Human, do you think she can escape?"

The Beast King, controlling Elfman, spoke with a cruel tone. He was going to torment this human who had defeated him, starting with her family.

Watching the "Beast King" approach step by step, regret couldn't help but rise in Mira's heart.

If she hadn't been too confident and underestimated the enemy, things wouldn't have come to this, with her and her siblings all trapped in danger.

Just then, the "Beast King" stopped in his tracks, a look of struggle on his face. It was Elfman's will! Just like the courage he had shown earlier when he charged at the Beast King for Mira's sake, how could he hurt his own family?

Seeing this, Lisanna actually walked towards her brother on her own.

"Elfman-nii, don't lose to that monster! Hang in there!"

Looking at the girl's innocent, radiant smile, "Elfman's" expression froze for a moment, then twisted into a cruel sneer.

"Sorry, but your brother can't hear you right now! Hahaha!"

Take Over Magic activated, Elfman's right arm transformed into the Beast King's massive claw. The Beast King wielded this body that had taken in its power with practiced ease.

The ferocious transformation and terrifying killing intent froze the naive Lisanna in place, staring blankly as her "brother" bared his claws at her.

If that claw came down, the girl would be crippled at best, dead at worst.

In that critical moment, a figure moved with incredible speed, snatching the paralyzed Lisanna from beneath the giant claw.

Boom!

A massive claw mark several meters deep appeared on the ground, the residual force even cracking the surrounding earth with several fissures.

The figure set the terrified Lisanna down beside Mira, then a voice rang out in complaint: "Facing a human controlled by a monster, you actually thought you could move them with love. What foolish naivety."

As the dust cleared, Mira finally saw who it was—a young man with white hair just like hers. For some reason, she felt like she had seen him somewhere before.

"Hey~ beautiful, staring at me like that, you're not thinking of offering yourself to me, are you? I'm not that kind of guy, you know~"

Noah chuckled lightly, but didn't see the madness flooding Elfman's pupils behind him.

Mira, however, saw it clearly and quickly called out a warning.

"Watch out!"

But it was too late. The Beast King's massive arm was already above Noah's head. Elfman could almost see the scene of brains splattering in the next second.
