Both humans were shrouded in immense and highly concentrated Mana.
For the boy, a sphere of flames covered him. His entire body was also glowing amber—as though covered by a thin layer of flames, rather than skin.
His previously brown hair now floated in the air, brimming bright red like flames.
The 'Elemental Chamber' he mentioned earlier had caused him to adopt this transformation. Even from where she stood, Rheas felt the intensity of his Mana.
It was terrifyingly hot.
However... that was nothing compared to the person beside him.
Her entire outfit had changed and a Grimoire now appeared before her.
The blue, black, and white energy swirling around her matched the apparel she now wore.
This was Mage Mode—the greatest state a Mage could achieve—allowing them a massive amount of power, though temporarily.
Why did such a young individual possess such strength?
Compared to the boy beside her, she was far more dangerous.
However, since they both emitted great power, it was difficult to ignore any of them. They had to be eliminated together.
Rheas, despite looking cunning and acting sky, was quite straightforward in situations like this.
"Demon Beasts, kill them both!"
All she had to do was order all the monsters to attack them at once until they grew exhausted and fell.
Their transformations wouldn't last forever, and the reason they probably adopted them was so they could boost their power.
'That means if they're out of that state... these two will stop being threats.' That was what she concluded.
And so, using her minions as sacrifices, Rheas observed from the rear.
'Now then, let's see how long you—'
>BOOOOOOOOOOOOOOOMMMMM!!!<
In a brilliant burst of fire and wind, several Demon Beasts met their instant end.
"E-eh...?"
>WHOOOOOSSSSHHHH<
The boy coated in flames flew high into the sky, using the intensity of the fire on his body to propel him to each target—taking down one Demon Beast at a time.
His capabilities were beyond normal! How could a single strike of his engulf giant monsters in flames?
At a point, he leaped high up and then descended with ferocious speed—like a meteor—decimating the fee dozen monsters around him.
He was like a god that punished Demons—purifying their darkness with his intense flames.
But... his actions were still nothing compared to the girl.
>BOOOOOOOOMMMMM!!!<
>BOOOOOOOOMMMMMMMM!!!<
>BOOOOOOOOOOOMMMMMMMM!!!<
Unlike the boy who flew up and about to defeat his prey, exerting himself beyond the limits of normal people, the girl never left her position.
From where she now levitated, she was launching highly destructive blasts toward the Demon Beasts.
It was crazy, but she was a literal one-man army.
A single blow could decimate a hundred Demon Beasts in a go—yet she did so effortlessly.
It was a pitiable sight, and Rheas could feel a terrible sense of dread befall her.
In a minute—no, maybe less—it was possible that her entire army would be done for.
'I haven't even... done anything yet...!'
Her eyes were fixated on the girl who was smiling playfully as she destroyed the Demon Beasts that were meant to devastate the Northern Border with her.
Fear coursed through Rheas' body. Still, a greater fear of disappointing her master made her unable to back down at this point.
"Y-you bitch... you ruined my plans." The Lamia growled, glaring at the human girl.
At this point, she too stared at the Demon General. She must have sensed her bloodlust.
"Oh? So you want to play too? Why not wait your turn?"
Rheas couldn't understand the human's words, but she felt like the girl was mocking her.
Her gaze was enough to tell the Lamia that much.
"You... you..." Rheas raised her staff, causing the black crystal atop it to glean even more malevolently.
She hadn't wanted to go this far yet—especially since they hadn't invaded the great walls—but the Lamia could not contain her rage.
She would suffer further disgrace if she didn't resort to her full strength.
—Peak Level Magic
'I'll use that to decimate this little girl!'
Yes, that was the fastest and easiest solution.
"Jerry, take care of the rest for a bit. I'm handling the boss." Even as Rheas began chanting the Spell, the girl had the audacity to look away.
'How dare she? How dare she?! How dare sheeee?!!'
In a few moments, she would be consumed in a flood of Miasma-infused acid. Screaming in despair and agony, the girl would suffer endlessly.
"H-hey, don't start without me!" The boy called out from a distance, still fighting the couple of Demon Beasts that were left.
"Too late. Hehe." The human girl was now looking in her direction.
The expression on her face was so full of confidence that it frightened the seemingly superior Lamia.
'Why are you smiling? You'll die, you know? I'll make sure to kill you and everyone else you care about!'
"What did you just think? You'll kill who I care about?" The air around the girl changed instantly.
Rather than her playful smile, a serious—murderous—look was now evident on her face.
It was frightening, so scary that Rheas didn't even ponder how the human girl was able to read her thoughts.
Still, the Lumia was almost down with her Spell. Any moment now, and—
"I wanted to take my time playing with you, but what you've thought is unforgivable."
The human girl made a pose as if to snatch something, and then spoke words that shouldn't have been uttered by someone so young.
"[Original Magic: Phantom Link—Brain Dead]."
Suddenly, something broke inside Rheas.
Her mind snapped, and she couldn't feel anything and anyone. Her vision darkened and her body helplessly fell.
Before Rheas could even make a final thought, or complete her Spell—before the Demon General could even realize it—she was dead.
As her neural links and core were completely destroyed by the human girl's Original Magic, she was now nothing more than a lump of meat.
"Nooo! You're already done?" The human boy sharply glided to the girl, undoing his transformation in a flash.
"Yep. I see you've finished up too. About time." The girl glanced around and saw that the Demon Beasts were all decimated.
Not a single one was left standing.
