The Greatest Assassin Gets Reincarnated in Tensura

I was sitting in my home, my mind racing.

These mysterious visitors… Who were they really?

No information. No data. Even Great Sage couldn't analyze them.

That alone was enough to make me uneasy.

My instincts told me they were beyond powerful.

And yet, despite that overwhelming presence, they were simply enjoying themselves in Tempest—shopping, eating, laughing—as if they were on vacation.

It didn't make sense.

Should I be worried? Should I just let them be?

I was stressing out.

Then, suddenly—

Souei appeared.

He knelt before me, his usual calm demeanor… slightly off.

That alone made me pause.

This was Souei—the silent specter, my most skilled shadow operative. He never showed emotion, never displayed uncertainty.

But now?

There was the faintest trace of hesitation.

"Souei?" I asked, my brows furrowing.

He lifted his head slightly and spoke, his voice as composed as ever—but with a noticeable weight behind it.

"My Lord, the visitors… They have decided to extend their stay in Tempest."

I blinked.

"...Alright? And?"

Souei hesitated.

Then, after a brief pause, he continued.

"He… played a trick on me."

I frowned. "What do you mean?"

Souei took a slow breath, as if recalling the moment in perfect detail.

"I was watching them from the shadows, undetected as always. My presence was completely hidden."

"Yet in an instant—without any warning—I felt a tap on my shoulder."

My eyes widened slightly.

"I didn't see him move. I didn't feel his aura. One moment he was with his group, the next… he was behind me."

Souei clenched his fists slightly, his pride clearly shaken.

"I didn't even realize he had disappeared until after he spoke to me."

I stared at him, my mind processing what he just said.

That's impossible.

Souei wasn't just some random scout—he was a master assassin, one of the best at detecting presence, reading movements, and sensing threats.

And yet, this man—this visitor—had moved behind him without a single trace.

Not even Great Sage noticed.

That wasn't just speed.

That wasn't just skill.

That was something far beyond comprehension.

Souei continued, his voice steady, but I could tell the experience had unnerved him.

"From my perspective, my Lord… it was as if time itself had stopped."

A chill ran down my spine.

Time stopped?

I immediately turned to Raphael.

("Great Sage, is that possible?")

"…Insufficient Data. No explanation available."

Damn it!

I sighed, rubbing my temple.

This was a problem.

These visitors were already beyond mysterious, and now they were playing with reality itself?

I leaned back in my chair, exhaling.

"...Souei, what's your opinion?"

Souei bowed his head slightly. "They are beyond us, my Lord. If they wished to take Tempest… there is nothing we could do to stop them."

I felt a weight settle in my chest.

I already suspected as much.

But hearing Souei—of all people—confirm it?

That made it very real.

I looked out the window, toward the bustling city where my people laughed and enjoyed themselves.

These visitors weren't hostile.

Not yet.

But their power was immeasurable.

And I had no idea what they truly wanted.

For now, I'd have to tread carefully.

----_____-----

In the Ice Continent, within the vast crystalline palace that served as his domain, Guy Crimson, the Primordial Demon, sat on his throne of ice, his piercing crimson eyes glowing with power and irritation.

The air around him was tense, a suffocating weight pressing down on everything within the chamber. Even the flickering torches seemed dimmer, as if they, too, feared the wrath of the Demon Lord who sat before them.

Standing in front of him were Clayman, Frey, and Carrion—three Demon Lords who had, not a long ago, waged a massive war that threatened the balance of the Cardinal World.

Guy had summoned them after the devastation their conflict had caused. Too many people had died. Too many cities had been reduced to rubble.

And if there was one thing Guy Crimson wouldn't tolerate—it was unnecessary destruction that threatened the world's delicate balance.

Now, the three Demon Lords stood before him, their postures tense.

Guy spoke first.

"Tell me," his voice was deceptively calm, yet layered with an unspoken menace. "What exactly possessed you three to start an all-out war? What justification do you have for the destruction you've caused?"

His eyes narrowed, the temperature in the room dropping dangerously low. Even Frey, who had a natural resistance to the cold, felt a chill run down her spine.

There was a brief silence.

Then—Clayman, the most cowardly of the three, stepped forward first.

Clayman, always one to weave a story to his advantage, bowed deeply before Guy, trying to look as humble as possible.

"Oh great Guy Crimson, I assure you, I had no intention of causing widespread destruction. I was merely seeking to expand my domain—"

SMASH!

Before he could finish, a shockwave erupted from Guy's throne as he slammed his fist against the armrest.

The force alone was enough to crack the ice beneath them.

"Bullshit." Guy's voice was now ice-cold, his crimson eyes glowing with fury. "Expanding your domain? You waged war, Clayman. Don't sugarcoat it."

Clayman flinched, sweat forming on his forehead.

But he quickly recovered and forced a nervous smile.

"I… admit, I may have been a bit ambitious." He straightened, regaining some of his composure. "But I had my reasons. Carrion has always been a wild beast with no regard for order, and I thought it was time someone put him in his place."

Carrion growled, but before he could lash out, Frey stepped in.

Frey, the Harpy Queen, took a step forward, her expression calm but firm.

"I won't lie to you, Guy. I joined this war because I saw an opportunity." Her golden eyes were sharp, unyielding.

Guy leaned back, unimpressed. "Elaborate."

Frey crossed her arms and continued.

"I knew that whether I got involved or not, Clayman and Carrion would fight. That's just the kind of people they are." She shot them both a glance. "If I stayed out of it, the balance of power among the Demon Lords would shift unpredictably. So I intervened—to ensure that no one came out too strong."

Guy raised an eyebrow.

"So, you're telling me that you threw yourself into a war—not for personal gain—but to maintain balance?" His tone was mocking, skeptical.

Frey smirked. "I wouldn't say I had no personal gain. But yes, that was part of it."

Guy studied her for a moment, then turned to Carrion.

Carrion, the Beast King, was not one to make excuses.

Unlike Clayman, who tried to manipulate the conversation, and Frey, who calculated her involvement, Carrion was straightforward.

He crossed his arms and met Guy's gaze head-on.

"I fought because I had to."

Guy's eyes narrowed. "You had to?"

Carrion nodded.

"Clayman provoked me, and I wasn't going to sit back and let him take what's mine. The Beast Kingdom is my responsibility. My people are my responsibility. If I let some arrogant puppet master push me around, then I don't deserve to rule."

Guy tapped his fingers against the throne's armrest. "So, your answer is simply pride?"

Carrion smirked. "Call it what you want. But I wasn't about to let Clayman walk all over me."

Guy listened to each of their explanations carefully.

Clayman was power-hungry and reckless.

Frey was calculating and opportunistic.

Carrion was stubborn and prideful.

Each had their own reasons, but none of them justified the sheer scale of destruction they had caused.

Guy let out a long, deep sigh, rubbing his temples.

"You three are ridiculous."

They flinched.

"I don't care about your excuses. What I care about is balance. And because of your little war, the balance of the Cardinal World was thrown into chaos."

The temperature in the room plummeted again.

"So, here's how this is going to go."

He pointed at Clayman.

"You're going to compensate for the destruction you caused. Your army wrecked cities, and I expect you to make amends—personally."

Clayman swallowed hard but nodded rapidly. "O-of course! Anything you say, Lord Guy!"

Guy then turned to Frey.

"Since you claim you were only 'maintaining balance,' you'll help restore it. That means you will oversee the rebuilding of the cities affected by your war."

Frey sighed but didn't argue. "Fine. I'll do it."

Finally, Guy's gaze locked onto Carrion.

"And you. Beast King. If you're so proud of your people, then you'll be responsible for protecting the lands affected by the war. Until they are stable again, you'll personally oversee their safety."

Carrion grunted. "Tch. If that's what it takes, then fine."

Guy leaned back, satisfied.

"Good. Because if any of you dare to start another war like this again…"

His crimson eyes flared, and a monstrous pressure filled the room.

"…I won't bother asking for explanations next time."

Silence.

Then, slowly, the three Demon Lords nodded in understanding.

The War Had Ended.

Balance had been restored—at least for now.
