Earth Land, a world brimming with magic.
Three continents gazed at each other across the ocean; they were the main body of this world.
In a valley on the border of the Fiore Kingdom, in the eastern continent of Ishgar, a battle was raging.
A dark purple magic circle rapidly expanded from the white-haired girl's left hand until it covered her entire body.
"Take Over Magic: Satan Soul!"
Once the magic circle disappeared, Mira's aura changed drastically. Her eyes were cold, and a tyrannical presence was unconsciously released. Her entire demeanor, like the magic she unleashed, was as if a female Demon King had descended.
The giant beast, feeling its authority challenged, let out a furious roar. The ground beneath its feet cracked from its powerful stomps, and the surrounding hillsides crumbled under its roar. Crushed rocks and dead trees continuously rolled down from the tremors.
Yet, this terrifying beast, capable of cracking the earth and collapsing mountains, was locked in an intense battle with the human girl, who was five times smaller than him.
Not far away, a burly man and a small, adorable girl watched this scene nervously. They shared one common trait with the girl on the battlefield: all had white hair.
The small girl watched the figure deftly weaving under the giant beast's fists with a mix of nervousness and adoration. "Eli, Big Sister is so amazing! She can fight an S-Class Beast King all by herself. I heard other guilds need at least two S-Class Mages, and even then, they might not be able to defeat a Beast King."
"Yes, Lisa. Mira is just that strong. If only I had half… no, even a third of Big Sister's courage, that would be great."
Despite the burly man's developed muscles, he was actually underage. And contrary to his tough exterior, the boy named Eli was gentle and somewhat timid.
The magic of the three siblings was all Take Over Magic.
The upper limit of this magic was closely related to the power that was Taken Over. This S-Class mission to subjugate the "Beast King" was taken on by Mira for her brother, Eli.
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 mountain walls to burst open again.
Narrowly dodging a heavy punch, Mira's expression was solemn. The strength of this mission's target was somewhat beyond her expectations. It was indeed a mission that required two or more S-Class Mages to team up to complete.
The stronger the Beast King, the more it spoke to his potential. If Eli Took Over this power, he should become more of a man, right?
Fighting the Beast King alone was difficult, but Mira had no thought of retreating. Her title of "Demon" was earned through real battles.
If she backed down because of a mere beast, she would surely be mocked by that red-haired freak when she returned.
Controlling darkness was Satan's most basic and core ability.
Mira gently pulled her single hand in the void, condensing a torrent of pure dark magic that surged towards the Beast King.
The power of this strike was enough to shatter a boulder.
But for the Beast King, it was merely an innocuous attack, leaving only a faint mark on his body with no other damage.
As an S-Class Magical Beast, the Beast King, though unable to speak human language, was not a beast of low intelligence. He looked at Mira with mocking eyes, full of provocation.
Seeing the Beast King withstand her magic with his bare body, Mira didn't get agitated by his provocation. It was just a minor skill, and many of her guildmates could withstand that move.
The test of the Beast King's defensive capabilities was over.
Next, it was time for the real offense.
The Beast King's shadow was like a small mountain, his giant fist carrying immense power, engulfing Mira entirely.
Mira's demonic wings on her back suddenly spread, deftly dodging the fierce attack. She rapidly spiraled up the Beast King's arm, facing his terrifying fanged maw.
Before the giant beast could retract his arm to defend, Mira unleashed her full power. Two masses of darkness gathered in her hands, creating a chaotic vortex of magic that enveloped the Beast King's head.
The air was rapidly compressed and depleted, and a sense of suffocation washed over him. The Beast King was temporarily unable to breathe, and his survival instinct made him burst out with speed far exceeding his usual.
The giant beast's palm struck. Mira subconsciously dodged, but because she was maintaining the magical vortex, she was still a step too slow. The huge palm directly grabbed Mira's body, holding her tightly in its grasp.
As the Beast King's large hand exerted force, all of Mira's bones began to creak. Against the Beast King's mountain-splitting power, the physical strength provided by Satan Soul was completely insufficient.
Her body was compressed by the immense force, as if she would be crushed the next moment. The intense pain made Mira cry out in agony.
"Ah!!!"
This scene made Lisa anxious, but her strength was low, and rashly entering the battlefield would only distract her sister.
"Eli…"
Lisa turned her head, but there was no sign of her brother, Eli.
Only at the bottom of the valley, a burly figure lunged at the giant beast, which was several times larger than himself. It was Eli!
Take Over Magic had not yet Taken Over any power. The current Eli was just a strong teenager. Trying to shake the Beast King was simply a pipe dream.
Eli also knew he was trying to crack a stone with an egg, but he couldn't stand by and watch his sister suffer!
A stinging pain in his calf, like an ant bite, made the Beast King notice the man biting his calf. His teeth—that was the only weapon Eli had that could harm the Beast King.
Although his skin wasn't even broken, the Beast King was furious at having his fun interrupted by such a weak human.
Shaking Eli off, the Beast King's huge foot lifted high, about to crush Eli into Eli paste.
Just then, a fierce, evil wind suddenly struck from in front of him. A strong sense of crisis made the Beast King's heart suddenly tighten. Terrifying dark magic condensed into a dangerous blade, slicing through the giant palm that held Mira.
"Ow!!"
Retreating with his wrist clutched, the Beast King didn't understand why the human he was just about to crush could suddenly unleash such terrifying power.
"Well done, Eli."
Forcibly unleashing her magic made Mira's already severe injuries even worse, but she was very happy because her timid brother had finally mustered the courage to save her.
Although blindly charging was brainless… "It's time to end this."
Her wings flapped, carrying Mira into the sky. She looked down emotionlessly at the wailing Beast King, and the purple-black magic circle reappeared, covering her entire body.
"Full Body Take Over: Demon God Halphas!"
Pale blue horns grew on her head, her hands and feet were covered with pale blue scales, and her demonic wings also transformed into matching colored Demon God wings.
The Demon King's posture receded.
The Demon God appeared!
Mira, in her "Demon God" form, possessed incredible speed, and her magic and destructive power overwhelmingly surpassed Satan Soul.
"This is the power the Master forbade me to use."
"To die by this power is your honor!"
With a pair of wings spread, Mira stood in mid-air. Beneath her calm eyes, she released an unusually violent fluctuation and killing intent.
The Beast King, infamous for his formidable strength and physique, not only did not retreat despite losing a hand but also completely unleashed his wild nature.
Pushing off with his legs, the Beast King leaped into the sky, roaring as he swung a powerful, heavy fist.
This time, Mira did not dodge. Instead, she clenched her five fingers and engaged the Beast King in a head-on battle.
A circle of white waves directly exploded in the air, stirring up raging winds. Eli, peeking out from his hiding spot, saw a scene he would never forget in his life.
The powerful Beast King was now slammed heavily to the ground, spitting out large mouthfuls of blood. The arm that had punched Mira was pulverized into a bloody mess, and large gushes of beast blood sprayed from the severed limb. His life force dissipated at a visible rate.
He killed the Beast King with one blow!
As expected of Big Sister Mira!
Eli looked up at Mira in adoration, not noticing the golden light gradually fading in the clouds above.
Mira slowly descended, and seeing her younger siblings running towards her, she smiled dotingly, then coughed up a mouthful of blood.
The Demon God form dispelled, and Mira collapsed weakly.
"Big Sister!"
Eli and Lisa looked at this scene in dismay, rushing towards her.
"I'm fine, just some minor injuries. I'll be fine after some rest."
Although Mira said so, even an ordinary person could see how serious her injuries were.
Not far away, the Beast King gradually stopped breathing.
Mira nudged her brother. "Eli, go. Go get the power that belongs to you."
A resolute look emerged in Eli's eyes. His sister had suffered such severe injuries for him; he absolutely could not disappoint her.
Walking towards the still-warm body of the giant beast, Eli struck while the iron was hot, activating his magic circle and pulling the Beast King's power towards himself.
"Hmph… Ah ah ah ah ah!"
His strong body was filled with pain. Enduring the intense mental agony, Eli successfully Took Over the "Beast King's Soul." If he developed it well in the future, he would be able to exert the Beast King's power in life, and even potentially surpass him.
"Big Sister! I… Ugh!!"
The joy on his face was instantly replaced by savagery. Eli's words of good news were not yet finished when his eyes were filled with violence, and he let out a painful roar.
The sudden change startled Mira and Lisa.
Feeling Eli's gaze on her, Mira inwardly cursed. The one controlling Eli now was the recently deceased Beast King!
Although she had defeated the Beast King, Mira had overlooked one thing: how could her brother so easily Take Over the power of a giant beast that she herself had struggled so much to defeat?
Whether in spirit or will, the current Eli was far from comparable to the Beast King.
"Lisa, run quickly!"
Severely injured, Mira was unable to fight further. She knew the Beast King resented her, so Lisa had a chance to escape.
"Hehehehehe~"
"Human, do you think she can escape?"
The Beast King, controlling Eli, spoke with a vicious tone. He wanted to thoroughly torment this human who had defeated him, starting with her loved ones.
Watching the "Beast King" approach step by step, Mira couldn't help but feel regret.
If she hadn't been so overconfident and underestimated her opponent, things wouldn't have escalated to this point, putting herself and her siblings in danger.
Just then, the "Beast King" stopped, a look of struggle on his face. It was Eli's will! Just like the courage he showed earlier when he charged at the Beast King for Mira, how could he harm his own family?
Seeing this, Lisa, surprisingly, walked towards her brother on her own.
"Eli, don't lose to that monster! You can do it!"
Looking at the girl's innocent and bright smile, "Eli's" expression froze, then turned into a cruel, sinister grin.
"Sorry, your brother can't hear you right now! Hahaha!"
Take Over Magic activated, and "Eli's" right arm transformed into the Beast King's giant claw. The Beast King found it easy to use this body that had Taken Over his power.
The vicious transformation and terrifying killing intent left the innocent Lisa stunned in place, staring blankly as "Big Brother" bared his claws at her.
If that claw strike landed, the girl would be dead or crippled.
Just at this critical moment, a figure, moving at an extremely fast speed, rescued the terrified Lisa from beneath the giant claw.
Boom!
A huge claw print several meters deep appeared on the ground, and the residual force even created several cracks in the surrounding earth.
That figure placed the scared-witless Lisa back next to Mira, and a mocking voice spoke: "Facing a human controlled by a monster, yet foolishly wishing to move him with love. Truly foolish innocence."
As the dust settled, Mira finally saw the newcomer. It was a young man with white hair, just like her. For some reason, Mira felt as if she had seen this person somewhere before.
"Hai~ Beautiful, looking at me like that, you're not thinking of offering yourself to me, are you? I'm not just anyone, you know~"
Noah chuckled, but he didn't see the madness filling the pupils of "Eli" behind him.
But Mira saw it clearly and quickly warned him.
"Watch out!"
But it was too late. The Beast King's giant arm had already reached Noah's head. "Eli" seemed to see the scene of brains splattering in the next second.
