The Invincible Full-Moon System

Demon Lord Kirgil was petrified, his body took a still pause like a statue.

He had hoped that some of the other Demon Lords survived so that he could reunite with them and join forces to defeat the enemy forces, or at least make a tactical retreat to fight another day, and as expected, the others were still alive.

But he wasn't expecting to see them in this kind of state.

Reality slapped him across the face as he regretted being an obedient slave to his own pride.

If even he was defeated, then what chances do the others have?

"W- Who did this...?" Demon Lord Kirgil asked, his voice trembling in utter fright.

Upon hearing this, Aructh and Mazel averted their gazes elsewhere, clear humiliation could be seen on their faces, "It's the leader of the new era's rising power. We tried to fight him and his forces, but we hardly put up any fight"

"It's the Werewolf... It's him, right?" Another question slipped out of his mouth.

Demon Lord Kirgil remembered the conversation he had with Flunra, about his new master, and he was now certain that the one that defeated and turned Aructh and Mazel was definitely this supposed new master.

Surprised, Aructh glanced at Demon Lord Kirgil with raised brows, "You knew him?"

"Yes, Arnulf the Special served a new Prince, and I suspected that it was him" Demon Lord Kirgil nodded, but he quickly shook his head. "Enough with this small talk, let's head back to the kingdom. I'm sure we can revert both of you back to normal"

"Elder Tilrith knew the forbidden ritual, she must be able to do it" He added firmly.

But he noticed a change in Aructh and Mazel's faces.

None of them moved from their spots and their expressions were that of hesitation and fear.

It surprises Demon Lord Kirgil as this kind of meek-natured reaction is not something Aructh and Mazel usually do, especially Aructh, "What's wrong? Come help me and leave this place! Caraptaros is definitely sabotaged, so we'll have to go by foot"

As he said that, another question then appeared in his mind.

"What about Olgaroz and Ranath? Where are the two of them?" Demon Lord Kirgil asked.

Upon hearing this, Aructh and Mazel looked at each other with a troubled look.

Looking at this, Demon Lord Kirgil could already feel a bad premonition that both of them were already dead. But instead of answering, Aructh and Mazel stepped to either side to Demon Lord Kirgil's confusion.

Only when the two of them stepped away that Demon Lord Kirgil realize his situation.

"How did I reach here?" Demon Lord Kirgil muttered in doubt.

Even though he was quite sure that he was going in the opposite direction of Caraptaros, using the wind that blew the rain as an indication of direction, he was surprised to find himself beside an open glade.

Relentless downpours still adorned the place alongside occasional bright lightning in the sky.

It was still dim and hindered the vision.

However, each of these intermittent lightning strikes illuminated a vast, dark lake at the heart of the glade, which jutted a colossal, round boulder in the middle. It's round and massive in size, a sight that Demon Lord Kirgil recognized instantly.

The colossal boulder in the lake was in fact, Caraptaros.

Compared to the time he left it here, the cracks on Caraptaros' skin are not glowing anymore.

Almost as if it was dead, devoid of demonic energy.

Demon Lord Kirgil gulped harshly as it turned out he lost his sense of direction and somehow reached here, the place that he wanted to avoid at all cost, trusting his guts that were telling him that this place was no longer secure and had become dangerous.

From the view of the glade, it seemed his guts were correct.

Not one Rastrikan Demons who were supposed to be revived here could be seen.

Adding to his distress, he noticed a silver sword thrust into the ground beside the lake, radiating an aura of thick holy energy. It was a grim indication that the remnants of his once-mighty legion had been wiped out again.

Moreover, none of them will be revived again, all of them died permanently.

But as he was in a horrified trance, a haunting voice pierced the rain and reached his ears.

"Are you looking for these two...?"

Thud!

Out of nowhere, Demon Lord Kirgil saw two headless bodies landing right before him.

A single glance revealed the grim truth, the headless corpses before him were unmistakably those of his kin and comrades, Olgaroz and Ranath. Both of their lives had been permanently extinguished, with no hope of resurrection.

Demons are known as an immortal and fierce force.

In ancient times, this nickname lingers because not all have access to Holy energy.

With the presence of Holy energy, killing Demons permanently is plausible.

Averting his gaze away from the lifeless forms of Olgaroz and Ranath, Demon Lord Kirgil's attention was drawn to a figure perched atop Caraptaros. He didn't notice this figure earlier, but now that he does, his danger senses instantly scream at him.

Cloaking in an enigmatic veil of darkness, the figure's full form is hidden.

It was almost as if the relentless rain served to further obscure and diminish his presence.

Moreover, this figure should be the one who spoke the words from earlier.

"No matter who you think you are, this offense will be paid by blood. For interfering with our vengeance, you had committed an extreme offense against the Demon race!" Demon Lord Kirgil tries to probe his way out using words.

Even though this figure is definitely strong, the Demon race has a reputation of its own.

If he played it right, he could still survive. Or at least that's what he thought.

Seeing that the figure doesn't reply with anything and only keeps gazing onward, Demon Lord Kirgil becomes even more daring, assuming that the threat is working, "You've done enough barbarity, and if you wish to be pardoned, then come with us to our kingdom and I'll guarantee your amnesty"

"You may not know me, but I am close with Elder Tilrith" He added, smirking pridefully.

Upon hearing the threat from Demon Lord Kirgil, Rex tilted his head slightly as his lips trembled, in the break of laughter. But he kept a steady gaze and raised his shrouded hand before flicking his fingers.

Swish...

Almost in an instant, the downpour immediately stopped, leaving only dark clouds in the sky.

Demon Lord Kirgil looked around with a frown.

Even though he couldn't see Rex due to the shrouding darkness, he could already tell that he was talking with the supposed leader of the new era's rising power that Aructh and Mazel mentioned before.

"Good, now, escort us back to th-"

Bam!

Just before he could finish his sentence, something hit the back of his knees.

It was strong enough to put the unsuspecting Demon Lord Kirgil to his knees, the gesture angered him and forced him to turn his head to the side. Only then that he saw a similar figure with glowing white eyes, a white-furred Werewolf.

Not giving him any chance to say anything, Adhara grabbed him by the nape.

She then pushed his head to face down to the ground.

Subsequently, Demon Lord Kirgil observed the approach of another figure, catching sight of a pair of legs advancing toward him from the opposite direction with a pinned head. Despite being puzzled, he knows that their attention is definitely bad.

It was then that the second figure, Ryze came to a halt directly in front of him.

Unknown to Demon Lord Kirgil who wasn't able to raise his gaze to see Ryze properly thanks to Adhara's gripping hand, Ryze turned around to look at Rex, seemingly asking if he really had to do this.

Rex returns the gaze, remaining motionless which is an answer enough.

Having no other choice, Ryze took a deep breath to follow through with his instructions.

He lifted the two daggers he held, Adhara's weapons, and then breathed fire into them, imbuing them with the potent power of Zaddrass. With a swift and forceful motion, he brought them down, piercing Demon Lord Kirgil's remaining hand and firmly securing him in place.

"Kaarggh!! Curse you!! You won't get away with this, bastards!" Demon Lord Kirgil yelped.

But no matter how much he struggled, he couldn't do anything.

Only when he's fixed on his spot that Adhara let go and head back to the edge of the lake alongside Ryze, letting the stage be taken over by Rex who was going to be the one to decide the fate of Demon Lord Kirgil.

"Everybody feared you, Demon Lord Kirgil" He started, jumping off of Caraptaros.

Landing gracefully on the ground, he began advancing, his eyes alight with a malevolent crimson glow that represents death. "Many have doubted my ability to defeat you," he sneered, "and it's going to be a hassle to be needing to show everyone about my power. So I'll have you volunteer to be a permanent testament to my formidable might, a lesson for all to witness"

Upon hearing this, Demon Lord Kirgil growled.

His burly body tries to break free, but the dagger doesn't budge at all from the earth.

Seeing his struggle, Rex chuckled in ridicule as he could already tell that Demon Lord Kirgil had been completely exhausted of his demonic energy. If it weren't for that, he would be way more than capable of freeing himself.

Is this Flunra's doings or is it the Slave Mark's doings? Either way, this is very good.

Rex nodded his head before he squatted before the pitiful Demon Lord.

"Fear nothing, Demon Lord Kirgil. After I'm done with you, you will be more legendary than ever" Rex's lips curled into a devilish smile, depicting the fierce punishment he would do to Demon Lord Kirgil. "Though you'll no longer remembered as a conqueror, nevertheless, your infamy will be unparalleled"

Upon hearing this, Demon Lord Kirgil gritted his teeth, "Do you not fear rex?!"

"Do you not fear rex from the Demon's wrath?! If you do this to me, then you will be humiliating the entire Demon race. You and the entirety of your forces would be doomed by then! All of us will come for you and stop at nothing!" He roared, realizing that his threat was useless.

It should've worked, so he was really confused as to why Rex was not fearful of them.

Despite his strength, the Demon race is not to be underestimated.

But as soon as he finished venting out his frustration, his eyes slightly widened when he realized what he had said, "R- Rex...? Why did I say that? I want to say D-Rex...?! What's happening to me?"

Realizing that he couldn't say what he wanted, and say Rex's name instead, he was puzzled.

However, in the next second when he raised his gaze to look at Rex, he gasped as Rex's appearance changed entirely. Now, he was adorned in sinister white clothing that was oozing with an insurmountable of holy energy.

A dense holy energy that terrified his entire being, almost like an Angel.

Upon seeing the horror in Demon Lord Kirgil's eyes, Rex frowned before his forehead ceased in realization.  Oh, is it the Minor Oustification taking effect? The bleak energy coming out of him suddenly grew more intense.

"Since you are going to die already, I'll give you the answer" Rex suddenly said.

Smirking wickedly, he then stares into Demon Lord Kirgil's soul and continues, "Just like you, I also happen to be close with Elder Tilrith. She and I were quite closer lately, and I suppose you don't know that"

"W- What do you mean by that...?" Demon Lord Kirgil asked, trembling.

Rex's wicked smile stretched even wider when he saw this reaction, he then dropped the news that would shatter Demon Lord Kirgil's entire mind, "In this world, the Rastrikan Demons, you are chaotic and unrestrained. Everyone hates you more than anything. So, I was given permission..."

"Do you want to guess who gave the permission to slaughter all of you?" He added.

Watching the dread on Demon Lord Kirgil's face grow more evident, Rex continued with a sinister chuckle, "Indeed, it was Elder Tilrith who offered you up... making a deal with me to exterminate all of you, regardless of the cruelty it would entail"
