White-Haired Siblings

Earth-land, a world brimming with magic.

Three continents faced one another across the sea, forming the main body of this world.

In a valley somewhere along the border of the Kingdom of Fiore, on the eastern continent of Ishgar, a fierce battle was underway.

A dark purple magic circle rapidly spread from the white-haired girl's left hand, covering her entire body.

"Take Over Magic: Satan Soul!"

When the magic circle vanished, Mira's presence changed completely. Her gaze turned cold, and a violent aura escaped her unconsciously. Her whole appearance matched the magic she had unleashed, as if a female Demon King had descended upon the world.

The giant beast, feeling its dignity had been insulted, roared in anger. Its heavy stomps cracked the ground, and the hillsides around them crumbled beneath its bellow. The tremors sent rubble and deadwood rolling down the slopes.

And yet this terrifying beast, capable of splitting the earth and toppling mountains, was locked in an even match with a human girl five times smaller than it.

Not far away, a heavily built young man and a petite, adorable girl watched the scene tensely. They shared one feature with the girl on the battlefield: all three had white hair.

The petite girl watched the figure nimbly darting around beneath the beast's fists, her expression tense and admiring. "Brother Elfman, Sis is amazing. She can take on an S-Class Beast King all by herself. I heard the other guilds need to send at least two S-Class Mages to deal with a Beast King, and even then, they might not manage it."

"That's right, Lisanna. Big Sis Mira really is that strong. If only I had half her courage... no, a third of it."

Despite the young man's well-developed muscles, he was still underage. And unlike his burly appearance, the boy named Elfman was gentle and somewhat timid.

All three siblings used Take Over Magic.

The upper limit of this magic depended on the strength one received. Mira had taken on this S-Class Mission to hunt the "Beast King" for the sake of her younger brother, Elfman.

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

The magic power in the valley grew increasingly turbulent and oppressive.

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

Mira narrowly dodged a crushing punch, her expression grave. The target of this mission was stronger than she had expected. No wonder it was a mission that might take two or more S-Class Mages working together to complete.

The stronger it was, the greater the Beast King's potential. If Elfman received this power, perhaps he'd finally start acting like a real man.

Fighting the Beast King alone was difficult, but Mira had no intention of retreating. She had earned her title as the "Demon" through hard work.

If she backed down because of some mere beast, that red-haired freak would definitely mock her when she got back.

Manipulating darkness was Satan's most basic and central ability.

Mira flicked one hand through the air, drawing out a raging torrent formed entirely of dark magic. It surged toward the Beast King.

The attack was powerful enough to shatter a boulder.

But to the Beast King, it was nothing more than a harmless blow. It left only a faint mark on its body and did no other damage.

As an S-Class monster, the Beast King couldn't speak, but it was no unintelligent beast. It looked at Mira with mocking eyes, its provocation unmistakable.

Seeing the Beast King withstand her magic with its body, Mira didn't let herself be provoked. It was only a minor spell, after all. Plenty of guildmates could take it head-on.

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

Next came the real attack.

The Beast King's shadow loomed over her like a small mountain. Its enormous fist carried the force of a thousand tons, engulfing Mira completely.

Mira's demonic wings suddenly spread behind her. She nimbly dodged the ferocious attack, then raced up the Beast King's arm and faced its terrifying, tusked maw.

Before the giant beast could pull back its arm to defend itself, Mira unleashed her full power. Darkness gathered in both her hands, forming a frenzied vortex of magic that engulfed the Beast King's head.

The air compressed at tremendous speed until it was exhausted, and a suffocating sensation rushed over them. Unable to breathe, the Beast King's survival instinct drove it to move far faster than usual.

The giant beast's hand lunged at her. Mira instinctively dodged, but maintaining the magic vortex slowed her down. Its enormous hand closed around her body and squeezed her tightly in its palm.

As the Beast King tightened its grip, Mira's bones began to creak. Against its mountain-splitting strength, the physical durability granted by Satan Soul was nowhere near enough.

Her body was crushed beneath the immense force, as if she would be pulverized at any moment. The intense pain made Mira cry out.

"Ah!!!"

Lisanna grew frantic at the sight, but she was too weak. If she rushed into the battle, she'd only distract her sister.

"Brother Elfman..."

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

At the bottom of the valley, a burly figure threw himself at the giant beast, several times his own size. It was Elfman!

Elfman's Take Over Magic had never received any power before. Right now, he was nothing more than a strong underage boy. Thinking he could shake the Beast King was sheer fantasy.

Elfman knew he was like an egg thrown against a rock, but he couldn't stand by and watch his sister suffer!

A sting in its calf, like an ant bite, alerted the Beast King to the man clinging to its leg and biting it. Teeth were the only weapon Elfman had that could hurt the Beast King.

He hadn't even broken the skin, but the Beast King was furious that such a weak human had interrupted its fun.

It flung Elfman away and raised its enormous foot high, ready to grind him into Elfman paste.

Just then, a fierce gust of wind rushed toward it from ahead. The sudden sense of danger made the Beast King's heart clench. Terrifying dark magic condensed into a dangerous blade and sliced through the massive hand holding Mira.

"Roar!!"

The Beast King clutched its wrist and retreated, unable to understand how the human it had nearly crushed to death could suddenly unleash such terrifying power.

"Good job, Elfman."

Forcing herself to unleash her magic power had worsened Mira's already serious injuries, but she was happy. Her timid little brother had finally found the courage to save her.

Though charging in blindly hadn't been very clever...

"It's time to end this."

Her wings beat, carrying Mira into the sky. She looked down at the howling Beast King without a trace of emotion as the purple-black magic circle appeared again, covering her body.

Full-Body Take Over: Demon God Halphas!

Pale blue horns sprouted from her head, and pale blue scales covered her hands and feet. Her demonic wings transformed into matching wings of the Demon God.

Her Demon King form disappeared.

The Demon God appeared!

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

"This is the power the guild master forbade me from using."

"To die by this power is an honor!"

A pair of feathered wings spread as Mira hovered in the air. Beneath her calm gaze, she unleashed an extraordinarily violent aura and killing intent.

The Beast King, infamous for its overwhelming strength and physique, didn't retreat despite losing a hand. Instead, its wild instincts surged to the surface.

It leapt into the sky with a push of its legs and roared as it swung a powerful punch.

This time, Mira didn't dodge. She clenched her fist and met the Beast King head-on.

A ring of white air exploded around them, kicking up howling winds. Elfman peered out from his hiding place in the corner, only to witness a scene he would never forget.

The mighty Beast King crashed heavily to the ground, coughing up mouthfuls of blood. The arm it had used to trade blows with Mira had been blasted into a bloody pulp, and streams of its blood poured from the stump as its life faded before their eyes.

She'd killed the Beast King with a single blow!

As expected of Big Sis Mira!

Elfman gazed up at Mira in admiration, failing to notice the golden light slowly fading from the clouds above.

Mira slowly descended. Seeing her younger siblings running toward her, she gave them an affectionate smile—then spat out a mouthful of blood.

Her Demon God form vanished, and Mira collapsed.

"Sis!"

Elfman and Lisanna stared in alarm and hurried toward her.

"I'm fine. They're only minor injuries. I'll be better after a little rest."

But even an ordinary person could see how serious her injuries were, no matter what Mira said.

Nearby, the Beast King gradually stopped breathing.

Mira nudged her brother. "Elfman, go on. Go claim the power that belongs to you."

A look of determination appeared in Elfman's eyes. His sister had suffered such serious injuries for his sake. He couldn't let her down.

He walked toward the giant beast's still-warm corpse. While it was still fresh, Elfman activated his magic circle and began drawing the Beast King's power into himself.

"Ghh... Aaaaaaah!"

Pain filled his strong body. Enduring the agony in his mind, Elfman successfully received the "Beast King Soul." If he trained well, he'd be able to wield the Beast King's power one day—and might even surpass it.

"Sis! I... Ugh!!"

His joyful expression instantly twisted into a grimace. Before Elfman could finish telling them the good news, his eyes filled with savagery, and he let out a pained roar.

The sudden change startled the sisters, Mira and Lisanna.

Seeing the way Elfman looked at her, Mira thought, This is bad. The Beast King that had just died was now controlling Elfman!

Although she had defeated the Beast King, Mira had overlooked one thing: how could her brother have received the power so easily when she herself had struggled so much to defeat the giant beast?

In both spirit and will, Elfman was still far weaker than the Beast King.

"Lisanna, run!"

Mira was too badly injured to fight again. She knew the Beast King hated her, so Lisanna might have a chance to escape.

"Heh heh heh heh~"

"Human, do you really think she can get away?"

The Beast King controlling Elfman spoke viciously. It was going to make the human who had defeated it suffer—and it would start with her family.

As the "Beast King" approached step by step, Mira couldn't help regretting what she had done.

If she hadn't been so overconfident and careless, things wouldn't have reached this point. Now she and her siblings were all in danger.

Just then, the "Beast King" stopped. A struggle showed on his face. It was Elfman's will! Just as he'd found the courage to charge at the Beast King for Mira, how could he hurt his own family?

Seeing this, Lisanna walked toward her brother of her own accord.

"Brother Elfman, don't lose to that monster! You can do it!"

At the sight of the girl's innocent, radiant smile, "Elfman" froze for a moment. Then his expression twisted into a cruel grin.

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

Take Over Magic activated, and "Elfman's" right arm transformed into the Beast King's enormous claw. Having received the Beast King's power, the beast used this body with ease.

The terrifying transformation and murderous intent left the innocent Lisanna frozen in place. She stared blankly as "her brother" bared his claws at her.

If that claw struck her, the girl would be dead or grievously injured.

At that critical moment, a figure moved at incredible speed and rescued the terrified Lisanna from beneath the giant claw.

Boom!

A huge claw mark several meters deep appeared in the ground. The lingering force even cracked the surrounding earth in several places.

The figure set the terrified Lisanna down beside Mira. Then came a taunting voice: "You're facing a human controlled by a monster, and you actually think you can reach him with love? What foolish naivety."

As the dust settled, Mira finally got a good look at the newcomer. He was a white-haired boy, just like her. For some reason, she felt as if she'd seen him somewhere before.

"Hey~ beautiful, if you keep looking at me like that, are you hoping I'll marry you? I'm not that kind of guy, you know~"

Noah chuckled, but he didn't notice the madness filling "Elfman's" eyes behind him.

Mira saw it clearly and hurriedly warned him.

"Look out!"

But it was too late. The Beast King's massive arm had already reached above Noah's head. "Elfman" could practically see the next moment, when Noah's brains would splatter everywhere.
