The Invincible Full-Moon System

Radiel pushed forward, desperate to hit Mavenna with his spell, but his efforts were in vain.

He couldn't budge from his spot.

Both of his arms were trembling hard with both muscles and veins bulging with strength, but there was absolutely no chance that he could overpower Rex's grip. Realizing that sheer fact—he decided to pull his lance back and leap away.

In this position, he wouldn't be able to do anything.

His best chance of actually doing something was to restart the battle, back to square one.

Clank!

Despite his strong pull, Radiel gritted his teeth and turned to look at Rex again.

'I can't push through him, and I also can't pull my weapon, I'm stuck!' He thought in vexation.

Once again, he failed to retrieve his lance from Rex's pinch.

Unprepared for such a formidable opponent, much stronger than him, he had no other choice but to abandon his weapon—and leaped back. His feet slid across the sandy stone ground of the castle, coming to a halt near the staircase.

Raising his gaze, Radiel saw Rex remain standing in place with the same wicked grin.

'He's not a Demon—then is he a Human? He must've had that Demoness as his slave,' Gazing at Rex intently, Radiel began assessing his appearance. 'But I thought the Humans are not, as they used to be anymore...'

Appearance-wise, Rex looked like a Human, but there was something off about him.

Radiel couldn't tell what, but Rex somewhat also looked inhuman.

'The Evil's End spell is a spell made to counter Demons, entirely—they wouldn't be able to be revived if they got killed by that spell, but the work of the spell, is not that simple,' He shifted his gaze to look at Rex's fingers—finding them unscathed. 'It's a holy spell that utilizes evil or bad karma as punishment.

Since the Demons were intrinsically evil, this spell is effective, but this person... he's unscathed'

Despite the spell being made for Demons, it would also punish those who are evil.

From a glance, Radiel could feel evilness radiating from Rex.

It should work on him, but it didn't.

Such a thing was impossible, and he sweat at the thought of the possible strength Rex had.

Darting his eyes left and right—Radiel could also see that alongside Rex and Mavenna, there was also another one, who appeared out of nowhere. Each one of them looked strong, much stronger than anyone he encountered on this continent.

Radiel was in a tight position, but he didn't want to leave Catherine with these people.

"Who are you? And what do you want?" He eventually asked demandingly.

Upon hearing this, Rex paused for a second as he had some thoughts inside his mind.

I wanted to ask if he knew anything about the Angel Legion's intention to confirm Catherine's answer, but I'm curious, what was that spell he used just now...? An Origin Holy Spell? Was he really able to use an Origin-rank spell despite his meager power? Or did he borrow that spell?

<Notice: the user's bad karma was being tampered with by a foreign power!>

<Dispelling the foreign power...>

<Completed!>

As he blocked Radiel's attack from earlier, this series of notifications appeared.

It seemed like the System intervened the spell somehow incited the System's intervention.

Because of that sudden event, Rex became curious about Radiel's extent of power.

Since this was his first time fighting a proper Angel, who didn't instantly give up like the way Catherine did—he wanted to keep this going and see what other powers an Angel has—Rex might find other interesting powers.

Let's call it a warm-up before confronting the Angel Legion.

Focusing back on Radiel, his grin widened. Now... What should I do to make him go all out?

"Me? I don't have anything I want from this, in particular..." Rex mused nonchalantly—making his way over to Catherine. "But now that I think about it, I think I want to finish my collection. I heard the Ancient Humans had many slaves. I was not particularly invested in having slaves but that Demoness changed my mind..."

As he said that, Rex wrapped his arm over Catherine's shoulder, smiling dauntingly at Radiel.

Upon hearing this, Catherine's expression paled, "E- Eh...? Pardon?"

It was not mentioned directly, but from the questions Rex asked, Catherine got the gist that he was particularly interested in the Angel Legion. He was hostile towards the Angel Legion and might be a great ally for the rebellion forces.

Currently, Rex was searching for the other Angels to make sure Catherine was not lying.

Despite not wanting the others to get into this, Catherine thought of this as a possibility.

Had Rex formed some trust in her words, that's the first step to make Rex an ally.

But she was not expecting it to turn out this way at all.

On the other hand, Radiel's blood began to rush faster when he heard this, his entire body from head to toe was trembling in anger. Flashes of the ancient past appeared in his mind, and he was becoming angrier with each passing second.

Seeing this, Rex savagely pulled Catherine closer and tapped her head condescendingly.

"I heard there weren't many Angels left—a lot of you weaklings were slaughtered in the past," Rex continued—instigating Radiel even further. "then doesn't that mean she's a rare item? I'm probably the only one who has an Angel as a slave right now, lucky me"

At Rex's vile words, treating Catherine, an Angel, as an object just like the Ancient Humans did in the past—the last straw of sanity in Radiel's mind snapped. Hs heart pounded with a final, powerful beat before adrenaline and holy energy surged through him.

His eyes bulged with anger as he glared at Rex.

"Vile being! I'll do the world a favor by vanquishing you!"

Swoosh!

Unleashing a violent shout, a pair of wings sprouted from Radiel's back, flaring to the sides.

Not wasting a single second, he dashed at Rex with blinding speed.

Despite being an Angel, a holy being of good, his gaze was dripping with murderous intent.

Before Catherine could react, and stop Radiel from doing what he was doing right now, he was already before her—his glowing brilliantly fist, heading toward Rex's face. Despite the sudden increase in strength, Rex still caught the punch effortlessly.

Bam!

Anticipating this, Radiel expertly twisted his hand and gripped Rex's arm firmly.

<Notice: The White Feather teleportation mark has been branded on the user!>

Upon doing that, Radiel's wings flared, shooting a feather each at both Evelyn and Mavenna.

It flew like a bullet, hitting both of them on their arm.

Looking down at their arms, both saw a glowing white feather mark, also branded on them.

As he successfully did what he intended to do—his resolute eyes turned towards Catherine, who was still processing, what had happened, "Run! I'll buy you time to escape! Don't worry, I'll catch up to you later!"

In an instant after that, the four of them turned into energy, disappearing from the scene.

From Rex's point of view, his vision was suddenly assaulted by a bright light.

He was blinded for a second but remained completely calm.

Moments later, the scene came back to him again, and he was now outside in the desert.

Scanning the surroundings, he realized that he was now right outside the castle.

Feeling concentrated energy from below, Rex looked down and saw a glowing white mark, the exact same one, Radiel had branded on him earlier. I was not expecting him to do this, and I was worried he might bring us far, but that was not the case. It was a short-distance teleportation spell.

Rex glanced to the side and saw Radiel standing stiffly, his energy swirling around violently.

I assumed teleporting three people at once was also hard for him to do.

On the other side—Evelyn, who was observing the exchange between Rex and Radiel from a safe distance shook her head and sighed. She slapped the dust off of her clothes before she gazed back ahead.

Mavenna on the side also fixed ahead, "Finish him already, why play with his food?"

"He's not playing with his food," Evelyn replied.

She already knew what Rex was doing from the start.

It was clear, at least for her that he was trying to make Radiel angry for some reason.

"What is he trying to accomplish with this...?" She mused to herself.

Rex, retaining his leisurely demeanor, headed over and stopped a distance away from Radiel.

He held his chin high, taunting Radiel even further.

"Because of people like you, my race has averted from the path of the Great Light," Radiel, in a wrathful state, muttered whisperingly. "Had you not followed your inner darkness like some animals, my race... the Angel race would still retain its light"

Upon hearing this, Rex tilted his head undisturbed, "So, what are you going to do about it?"

"I'm standing right here, still alive and well" He added condescendingly.

Eventually—Radiel raised his eyes to look into Rex's eyes, his wrathful glare had transformed into a cold and calm gaze. Not responding with words, his eyes began to glow, and suddenly a whistling, rampaging sound of wind arose from afar, pulling Rex's attention.

Looking to the source of the sound, Rex saw a powerful sandstorm barreling towards them.

An event clearly orchestrated by Radiel from the looks of it.

Hmm...? An Angel controlling a sandstorm? No, I don't think that's the case.

Reaching his hand to the side, Rex summoned Devo, who instantly created a black lightning field to protect both Evelyn, and Mavenna. Devo managed to finish the field right before the sandstorm reached them.

Swoosh!

Pheew~

Instantly, the sandstorm assaulted the senses with its irritating windy sound.

But Rex stood rooted, undisturbed by the storm that could shatter rocs and lift buildings.

As he fixed his eyes on Radiel again—curious as to what he was planning to do since it didn't seem like an attempt to escape—Radiel began to flap his wings, and ascend from the ground in a slow manner, his eyes glowing with bright white energy, determined to take Rex down.

"I'll teach your prideful self," He said raspingly. "Picking a fight with an Angel is a mistake!"

Upon saying that, Radiel flapped his wings, propelling him backward.

He was submerged in the swirling mass of the sandstorm, only his glowing eyes visible until he vanished entirely. Finding that Radiel's trace of energy, disappeared, Rex frowned, "Stick close to me, don't get too far away" He said to the others.

Even though turning into his Werewolf form would help him locate Radiel, he didn't do that.

If I do that, where would the fun be? I wanted to see what he was capable of.

Coming from the side, Evelyn asked lightly, "He disappeared, can you locate him?"

"Normally, I wouldn't be able to locate him unless, I take this seriously," Rex muttered, both of his eyes darting left and right. "But he knows how strong I am, he's only acting tough, he was scared inside, and that's not a good thing. If you ever faced me—Evelyn... do not be afraid or you will lose"

Listening to this, Evelyn hits him on his shoulder, "Do you really have to say it like that?"

"I'm just saying," Rex replied, chuckling lightly.

Blitz!

Just then, however, Rex's right hand began to crack with powerful sizzles of black lightning.

He controlled his spirit energy and created a black lighting javelin.

Even though the powerful sandstorm, obscured his senses—Rex had other means to locate his enemies. One of them was the bleak energy radiating from a fearful foe, allowing him to have a predatory sense to anyone who acted like prey regardless of the situation.

Grinning lightly, his eyes flickered with vicious lightning streaks as he gripped the javelin.

In one fluid motion, he turned abruptly and gazed to his behind.

Peering through the thick sandstorm, he hurled the javelin with great strength and precision.

Swoosh!

Blitz!

Cutting through the wind easily, the javelin crackled fiercely, as it pierced through the dense sandstorm like a wheezing cannonball. On the other side, Radiel, hiding within the storm and preparing his next move widened his eyes.

His eyes saw a blitz of lightning speeding toward him, faster than his perception.

Before he could react, his head was yanked back violently.

As if Rex could see through the sandstorm, the black lighting javelin struck, stabbing through Radiel's forehead, and propelling him backward. Seeing that he hit his mark—Rex's smile was stretching wider.
