The Reincarnated Assassin is a Genius Swordsman

“That is…?”

Raon swallowed hard, echoing Sloth’s words.

“…….”

Sloth started to continue, then blinked vacantly.

“What was it…?”

He tilted his head slowly, as if he had suddenly forgotten.

》”That pathetic wretch!”

Wrath gnashed his teeth as he looked at Sloth.

》”He is bringing shame upon all Demon Kings single-handedly! Smash his head in this instant!”

He shouted for Raon to let him out so he could personally pummel Sloth.

“Ah… I remember now….”

Sloth tapped his forehead and nodded.

“In… my current state… when fighting an Archangel… it’s hard to… exert my full power….”

Sloth lightly curled and unclenched his fist with a hand that seemed completely drained of strength.

“Hard to use your full power? Weren’t you using your full power when you fought me?”

Raon lowered his brows, looking at Sloth.

‘He was definitely serious at the end, wasn’t he?’

When Sloth had wrapped himself in those black shadows, Raon had felt certain that victory was impossible. That must have been his full power; he didn’t understand why Sloth suddenly couldn’t use it.

“Fighting… an Archangel… is different….”

Sloth slowly raised his gaze to look at the dim sky.

“In the Human Realm… which is neither Heaven… nor the Demon Realm… if I fight an Archangel… the rules of the world… will be distorted….”

He closed his eyes, explaining that if a Demon King and an Archangel fought at full strength in the Middle Realm—a place where the Celestial and Demon races were not originally meant to exist—causality would collapse.

“Moreover… it’s a fight… that doesn’t suit… my instinct of Sloth… so I need a medium… even more….”

“So you’re saying you need a medium to bear the causality so you can draw out your full power?”

Raon understood Sloth’s words and immediately provided the answer.

“Correct….”

Sloth nodded, confirming it was accurate. However, he did not open his eyes again.

“A medium…”

Raon ran a hand through his hair, his brow furrowing.

“Where do I find such a thing?”

To bear Sloth’s causality, one would likely need compatibility with Sloth, but Raon had no idea where or what to look for. (T/N: Runaan?)

‘If this is the case, I won’t be able to call the other Demon Kings besides Sloth.’

Sloth’s words applied not only to himself, but to the other Demon Kings as well. If he wasn’t careful, his entire plan could fall apart.

‘If the Demon Kings don’t help…’

It would be a certain defeat.

No matter how much the Sword Monarch and Blade Monarch participated, the seven Archangels and countless Celestials would launch an assault in the final war. Without the strength of the Demon Kings, victory was impossible.

“That’s… simple….”

“Wait a second.”

Raon raised his hand, cutting Sloth off.

“If you need a medium, wouldn’t the Archangels and Celestials also need someone to bear the causality?”

The world was foreign not only to the Demon Kings, but to the Archangels as well. To fight the demons with their original power, they would inevitably need a medium just like Sloth.

“True….”

Sloth murmured in agreement and nodded. Even in such a critical moment, he seemed to want nothing more than to sleep.

“Then they’d both be in a state where they can’t use their original power… no, that’s probably not it.”

Raon bit his lip and shook his head.

‘If it’s Derus, he’d sacrifice humans to create a power that allows the Archangels to ignore causality.’

Knowing Derus Robert, he would undoubtedly distort causality by killing ten thousand—no, hundreds of thousands of people—just so the Archangels could exert their original martial power on this continent.

》”Correct.”

Wrath nodded heavily.

》”As you said, it is difficult for Demon Kings to use their full original power in this world. However, there are many other ways to achieve it.”

He twisted his lips, explaining that human souls or blood could be offered as sacrifices to unlock an Archangel’s martial power.

“Haa…”

Raon let out a hollow sigh.

‘The more I think about it, the more it feels like the Demon Kings and Angels have been swapped.’

The Archangels wanted to annihilate humans, while the Demon Kings, conversely, wanted to protect them. He wondered what idiot had come up with the concept that angels were good and demons were evil.

》”I told you! Humans have such severe prejudices!”

Wrath shook his head vigorously.

》”It’s true there are many bad ones among the Demon race, but the Celestial race and humans are no different!”

He bared his teeth, arguing that it was a matter of individual character, not racial difference.

“The method… is simple….”

Sloth raised a finger and pointed to the black flower bracelet wrapped around Raon’s wrist.

“The bracelet?”

“The… bracelet… I gave you… contains… the Sloth of this world… that you created…. With that power… I should be able to… draw out… my full strength….”

He nodded, explaining that he could draw out his martial power using the power of Sloth imbued in the black flower bracelet.

“What? That’s simple.”

Raon smiled and touched the bracelet.

“However….”

Sloth’s pupils flickered with a black light, just as they had when he fought Raon.

“After using that power… the Authority of Sloth you’ve built up… will all disappear.”

He shook his head, stating that this was the price for using the power.

“A price…”

Raon looked down quietly at the second black flower bracelet on his wrist.

“Still, it’s not a big deal.”

》”N-Not a big deal?!”

Wrath’s eyes widened.

“What…?”

Sloth’s eyebrows twitched, and he slightly turned his body. It was the most intense reaction he had shown all day.

“Unexpected….”

He lowered his brows as if he hadn’t anticipated such a response.

“What is?”

Raon tilted his head.

“While sleeping here… I have seen… many humans…. Humans… have a very… strong obsession… with power…. They are more… vicious than demons. Yet, you’re showing… such a reaction… even though the power… already in your hand… is disappearing….”

Sloth spoke the longest sentence since they had met, sounding genuinely surprised.

“It wasn’t my power to begin with.”

After completing his revenge against Derus, Raon intended to return all the abilities he had gained thanks to Wrath. Since he also harbored the desire to become the greatest sword master through his own strength, he didn’t feel like he was losing anything.

“You… are truly… a human….”

Sloth let out a sincere expression of admiration.

“Actually… regardless… accepting it… is right…. The only other way… is to find a human… whose wavelength matches mine….”

“A human whose wavelength matches?”

Raon narrowed his eyes at Sloth.

“Just as… you became the vessel for Wrath… and twisted causality… if there is a human whose wavelength matches… I could use… all my Authority… without taking… all your power….”

Sloth nodded, unable to resist the drowsiness.

“But… the humans… I’ve seen… were all… too diligent…. A human like me… would be hard to find….”

He sighed, noting that there were no humans who slept twenty-four hours a day.

》”He’s right. Where in this world would you find a sleepyhead who loves sleeping as much as this guy… Gasp!”

Wrath stopped mid-sentence, his eyes widening.

》”T-There is one!”

He seemed to have thought of someone who would get along well with Sloth.

“Evelyn!”

Raon called out Evelyn’s name, having thought of the exact same person as Wrath.

“Can you go to Zieghart right now and bring someone back?”

“Of course!”

Evelyn nodded, stating she would do anything Raon asked.

“Who should I bring?”

“From Zieghart…”

Raon curled his lips into a smile as he looked at Sloth, who had already begun to doze off.

“The person who sleeps the most.”

As soon as Evelyn left for Zieghart, Sloth declared he had finished saying everything and crawled under the covers. It was an enviable ability to fall asleep the moment his head hit the pillow.

“D-Did it work out well?”

Dorian blinked, covering Sloth’s face with the blanket. Despite saying he was scared, he was quite efficient at covering the face.

“I think a better result will be possible if things go well.”

Just as Raon nodded with a faint smile—

Thump!

The Sword Monarch and the Blade Monarch arrived at the summit of Stehrin Mountain using their movement techniques.

“We have handled the parts we broke for now.”

The Blade Monarch nodded, stating they had tidied up what they could.

“We’ll leave the rest to Parateus when he arrives.”

The Sword Monarch smiled brightly, intending to hand over the tedious parts to Gold Dragon Parateus.

“Ah, is this person Raon-nim’s friend?”

She tilted her chin toward Sloth, who was covered in blankets.

“That’s correct.”

Raon nodded, lightly tapping the bed where Sloth lay.

“He is incredibly strong. However, his energy is peculiar. It’s almost as if he’s not human….”

The Blade Monarch narrowed his eyes, seemingly sensing the aura of Sloth emanating from him.

“Whatever the case, we should apologize first.”

The Sword Monarch approached Sloth’s bed and bowed her head.

“I’m truly sorry for waking you up and destroying the mountain.”

She clasped her hands, saying it wasn’t intentional.

“I heard you were unable to sleep because of us.”

The Blade Monarch let out a thin sigh and stood before Sloth.

“I offer my sincere apologies.”

He also spoke a solemn apology from the heart.

“I am the Blade Monarch, and this person is the Sword Monarch. If there is anything we can do for you, please tell us.”

The Blade Monarch nodded, promising to grant any request.

“Ummm….”

Sloth’s thin voice drifted from beneath the blanket. It seemed he had been awakened by the energy waves of the Sword Monarch and the Blade Monarch.

Ssssh.

Sloth lowered the blanket slightly and looked into the eyes of the Sword Monarch and the Blade Monarch.

“It’s fine now…. Just… don’t do it… again….”

Having received their apology, he waved his hand as if telling them to leave and closed his eyes.

Zzzzz.

The moment he closed his eyes, Sloth fell back into a deep sleep, letting out a cute snoring sound.

“Ha…”

The Sword Monarch let out a bewildered laugh.

“We revealed our epithets, and he asks for nothing?”

Her eyes widened as if something completely unimaginable had happened.

“He is a kind soul.”

The Blade Monarch nodded, watching Sloth smack his lips in his sleep.

“Both Raon-nim and this gentleman… to think such people still remain in this world, it is a blessing.”

He wore a warm smile, believing Sloth would do good things for the continent.

“Uh…”

Raon let out a hollow sigh, looking at the Sword Monarch and Blade Monarch, who were gazing at Sloth with affectionate eyes.

‘This actually worked?’

The Sword Monarch and Blade Monarch had never met a Demon King, and since Sloth had fallen asleep without releasing his Sloth, they only thought his energy was strange and didn’t suspect he was a Demon King.

[Heyyyy!]

As Raon scratched his head in disbelief, a massive shout echoed from the sky. It seemed Gold Dragon Parateus had finished clearing the glacier and followed them.

[Are you guys really going without me! You stingy humans!]

Parateus growled at the Sword Monarch and Blade Monarch, sounding irritated.

“Why are you so late!”

The Sword Monarch, however, frowned at Parateus.

“Dragons aren’t omnipotent after all.”

The Blade Monarch also sighed, noting that he had become much weaker.

[You told me not to damage nature! That meant I had to do it by hand!]

Parateus trembled his wings, explaining that it had taken a long time because he had to tidy up with his own body instead of using magic.

[You guys really… huh?]

He stopped abruptly while frowning at the Sword Monarch and Blade Monarch.

[W-What? Why is a Demon King here!]

Parateus gnashed his teeth as he looked at the sleeping Sloth. It seemed he had recognized Sloth’s identity through dragon instinct.

[Everyone move! I’ll kill him!]

Parateus opened his mouth, preparing to fire a breath to annihilate Sloth in one blow.

“Is he crazy!”

“Stop!”

The Sword Monarch and Blade Monarch leaped into the air and smacked Parateus’s snout just as he was preparing his breath.

Bam!

Without even a single groan, Parateus’s mouth was slammed shut, and he plummeted to the ground.

Kaboom!

Because of Parateus’s massive physical body, the entirety of Stehrin Mountain shook.

Zzzzz.

However, Sloth did not wake up, as if it were all completely irrelevant to him.

[W-What are you doing!]

Parateus screamed, glaring at the Sword Monarch and Blade Monarch.

“How could such a kind soul be a Demon King!”

The Blade Monarch shook his head vigorously, telling him to cast aside his doubts.

“Exactly! He’s the kindest person I’ve ever seen!”

The Sword Monarch wrinkled her nose, warning him not to even show his claws toward Sloth.

[No, I’m telling you, he’s a Demon King! Look at that wicked aura!]

Parateus pointed at Sloth, urging them to look properly.

“Hmm….”

Sloth smacked his lips briefly and turned his body to the left. A smile of pure happiness was drawn on his lips.

“That?”

“A Demon King?”

The Sword Monarch and Blade Monarch clenched their fists, telling him to stop talking nonsense.

[No, really! You don’t believe me? I’m Parateus of the Gold Clan!]

Parateus shook his massive tail wildly, pleading for them to trust him.

“I’d rather trust the Demon King than you.”

The Sword Monarch waved him away.

“If you say one more word of nonsense, I’ll rip those horns out.”

The Blade Monarch also drew his blade, telling him to stay still.

[Aaaaagh!]

Parateus screamed toward the sky, devastated that he couldn’t capture a Demon King right before his eyes.

[He really is a Demon Ki—Gah!]

He shouted that Sloth was a Demon King until the very end, only to be hit with a flick to the forehead by the Sword Monarch and Blade Monarch, sending his head crashing back into the ground.

》”Hey, ask him.”

Wrath tapped Raon’s shoulder.

》”Why on earth is that lizard being kept captive!”

He was now dying of curiosity, flopping around like a fish.

‘I’m curious too, but…’

Raon shook his head as he looked at Parateus, who was sniffing sorrowfully.

‘I don’t think now is the time.’

Vroooom!

A blue dimension opened, and Evelyn popped out.

“I’m back!”

Evelyn waved her hand, announcing her return from Zieghart.

“It really is far. I’m exhausted.”

She wiped the sweat from her forehead, saying it was tiring to ride dimension doors consecutively.

“Good job. The person I mentioned is…”

“Here.”

Evelyn smiled brightly and extended her right arm, which was still inside the dimension door.

“Ugh….”

From behind her, Runaan walked out with a low groan.

“Did you really call me…?”

Runaan was dressed in pajamas, clutching a blanket tightly while her wrist was held by Evelyn. She looked to be in a foul mood, having been dragged away while sleeping.

“I did.”

Raon nodded with a smile.

“How much do you usually sleep? On days you don’t train?”

“Continuously….”

Runaan didn’t mention a specific time, but used the word continuously.

“Continuously?”

“Yeah. Until I want to eat bead ice cream.”

She nodded, explaining that she didn’t wake up until then.

》”Perfect.”

‘Perfect.’

Raon muttered that he had found the right person and snapped his fingers.

“Then, would you be interested in gaining a new power?”

Although Sloth wasn’t a bad power, Raon asked first in case Runaan was reluctant.

“What kind of power…?”

Runaan blinked sleepily.

“If you want, you’ll gain the Authority of Sloth. The power of a Demon King.”

Since Runaan was someone he trusted, he told her honestly.

“Gasp!”

Dorian’s mouth fell open, and he fell flat on his backside.

“Hmm.”

Evelyn looked at Raon and Runaan with interested eyes.

“Will that help Raon?”

“Not just me, it’ll be a great help to you as well.”

He wasn’t just saying it. If it were Runaan, she could grow through Sloth and exert martial power on a completely different level than before.

“Then I’m okay with it….”

Runaan nodded, trusting him.

“Thanks.”

Raon smiled faintly and gripped Runaan’s shoulder.

“Sloth. Wake up for a second.”

Since the Sword Monarch and Blade Monarch had gone to comfort the still-crying Parateus, he figured now was the best time.

“Ummm….”

Sloth slowly opened his eyes and locked gazes with Runaan.

“…….”

“…….”

Sloth and Runaan said nothing, simply staring at each other with vacant eyes.

It looked as if two masters were recognizing one another.

“…….”

Sloth blinked slowly, then fell back asleep.

“…….”

Runaan likewise rolled herself up in the blanket she had brought and began to sleep.

》”Eh?”

Wrath’s lips trembled as he looked back and forth between Runaan and Sloth, who had fallen asleep simultaneously as if in a competition.

》”W-What is this! What kind of test is this!”
