The Greatest Assassin Gets Reincarnated in Tensura

Velzard sat alone on the balcony, the wine glass resting between her fingers. The moonlight bathed her in an ethereal glow, the Ice Dragon's elegant form radiating an aura of majestic indifference.

But her brows furrowed slightly, annoyance flickering in her ice-blue eyes.

"That bastard demon…" she muttered under her breath, swirling the wine in her glass.

Guy had just vanished.

No explanation. No warning.

One moment he was beside her, and the next—gone.

"What kind of nonsense is this?"

She took a sip, but then—

The atmosphere changed.

A subtle shift in reality.

Not cold, not warm, but something… new.

Velzard's entire being tingled with awareness.

Her instincts screamed something was off.

Even though she was still seated, the world felt different.

Then—

A hand touched her shoulder.

Soft. Confident. Effortless.

A touch that sent a shiver down even her spine.

Velzard jumped, turning swiftly—expecting Guy.

But it wasn't him.

It was someone else.

Someone she had never seen before.

And when her ice-blue eyes locked onto him, she froze.

Before her stood a man.

No—something more than a man.

A being of absolute perfection.

Tall, graceful, radiating an aura of unshakable supremacy.

His features were impossibly refined, almost unreal.

Velzard had seen many beautiful creatures in her long existence.

But this…

This was different.

Her breath hitched.

She had never seen a man more handsome.

No—not even Veldanava, her own elder brother.

His golden eyes gleamed with a calm, knowing amusement, as if he could see every thought racing through her mind.

A smile touched his lips.

A smile that felt dangerous.

"Velzard."

His voice was smooth, deep, and perfect.

Her face burned.

She never blushed. Never.

She wanted to speak—to demand who he was, what he wanted.

But her throat tightened.

Her heart pounded.

She was still processing what she was seeing.

For the first time in her existence…

The Ice Dragon was at a loss for words.

Arion sat down gracefully, his movements smooth, deliberate—effortlessly commanding.

The moonlight reflected off his flawless form, making him look almost ethereal, as if he was something beyond reality itself.

He leaned back slightly, eyes never leaving her, and spoke in a calm, velvety tone.

"Hello, Velzard. I believe this is the first time we are meeting officially."

His voice carried an undeniable authority, yet there was warmth in it—like a ruler addressing someone special.

Velzard's mind raced.

"Officially…?"

Had they met before?

She narrowed her ice-blue eyes, trying to place his presence.

Then—she remembered.

That energy.

The unseen force that had intervened when Guy faced Milim.

The unfathomable pressure she sensed when they fought Ivarage.

Her lips parted slightly as realization hit her like a storm.

"So… it was you."

She didn't need to ask. She already knew.

Velzard, now composed, crossed her legs and folded her arms, regaining her usual regal demeanor.

Her voice, once hesitant, now held confidence.

"Who are you?"

Her gaze hardened, attempting to mask the lingering flustered feeling inside her.

"And it is rude to just barge in without being invited."

She expected intimidation, or at least an arrogant response.

But instead—

Arion simply chuckled.

A deep, amused chuckle.

It was low, smooth—dangerously mesmerizing.

His golden eyes gleamed as he tilted his head slightly, watching her with quiet amusement.

Then he spoke—words that sent Velzard's mind spiraling.

"Indeed, Velzard. You are very cute when you're blushing."

Velzard's entire body stiffened.

Her eyes widened slightly, the words hitting her like a spell she wasn't prepared for.

"N… No… I'm not blushing."

Her voice wavered—damn it.

She wasn't used to this.

Was this embarrassment?

Fluster?

Velzard, one of the primal dragons, a being feared and respected across the world—was now fumbling over her own words.

Before she could regain control, Arion moved.

Effortless. Smooth.

His hand reached out, fingers brushing through her long, silky blue hair.

A gentle caress.

Not rushed. Not forceful.

Just… natural.

Velzard's breath hitched.

She felt the warmth of his touch, the contrast to her naturally cold body.

No one had ever touched her like this.

Not even Guy.

"You have very beautiful hair."

His voice was soft, but the depth in it made her heart pound.

Velzard, still unable to meet his golden gaze directly, lowered her eyes slightly.

Her lips parted, but the words came out softer than she intended.

"T…Thank… you."

Why was she acting like this?

Why couldn't she control this feeling?

Arion's smile deepened.

He knew.

He knew exactly what he was doing to her.

Arion's expression changed.

The teasing warmth in his gaze vanished, replaced by something stern, something absolute—as if the very fabric of reality had shifted to accommodate his will.

He leaned forward slightly, his golden eyes locking onto Velzard's, but this time there was no amusement—only unwavering certainty.

"Guy Crimson is no more."

His voice was calm, final.

"He will resurrect in a few years."

The words hung in the air, heavy like an unspoken decree.

Velzard's hand froze mid-motion as she was about to reach for her wine glass.

Her eyes widened, shock flashing across her face.

"What…? You killed Guy?"

Her voice wasn't just filled with surprise—it carried disbelief.

Guy Crimson—the Strongest Demon Lord.

Unrivaled for eons.

Yet, Arion had said it so simply, so effortlessly.

Had he truly been defeated?

Arion met her gaze, unshaken.

"He was supposed to be the mediator of this world," he stated, his tone holding an edge of cold truth.

"But he and Rudra have turned their game into something far more reckless. It has gone too far."

Velzard's mind raced.

She clenched her hands, nails slightly pressing into her palm.

She knew Guy had a tendency to toy with things—to push limits, to let his demons rampage when he deemed it amusing.

But this?

This was the first time someone had acted against him.

Velzard took a deep breath, trying to process it.

And then—the realization struck.

"That's why he suddenly vanished… Without a word…"

Her voice lowered, almost as if she were speaking to herself.

The memory replayed—Guy, sitting beside her, drinking wine, his usual smirk in place—then gone in an instant.

She had assumed it was one of his many whims.

But instead—this had happened.

She lifted her gaze back to Arion, her cold determination returning.

"What gives you the right to decide that?"

Her voice was sharper now, more demanding.

"My brother, Veldanava, was the one who gave Guy that role. He has always acted this way—even when my brother was still alive."

Her heart pounded in her chest as she said those words.

Veldanava.

The Creator.

The one who set all things in motion.

She stared at Arion, waiting for his answer, expecting resistance, maybe even anger.

But instead—he merely nodded.

"Yes," Arion said, voice steady, undisturbed.

"He has."

He leaned forward slightly, his presence overwhelming, yet not in a way that suffocated—rather, it was like he commanded existence itself.

"But Veldanava is no more."

He let the words linger.

A beat of silence.

Velzard felt an unnatural chill creep through her, despite her very nature being ice itself.

Then—he spoke the next words.

"And I am his successor."

The Moment of Realization

Velzard froze.

Her entire body went still, as if the world itself had momentarily stopped.

Her mind screamed at her to react, but she couldn't—she just sat there, staring at him, feeling as if she were being swallowed by something vast, something beyond comprehension.

Successor.

Veldanava's… successor.

It didn't just mean power.

It meant authority.

It meant purpose.

It meant—

Her breath hitched.

"Then that means…"

Her voice was barely a whisper.

Her thoughts spiraled, searching for answers.

No wonder.

No wonder he was this strong.

No wonder he carried himself with such certainty.

No wonder—

Her brother never mentioned him.

Was this the hidden will of the Creator?

Was this always meant to happen?

She gripped her dress, fingers trembling slightly.

Not from fear.

From awe.

From the sheer magnitude of the revelation.

She slowly lifted her gaze, staring into Arion's golden eyes—seeking truth.

And what she saw there was undeniable.

Absolute.

The will of a being who had surpassed even the Divine.

Breaking the silence, Arion leaned back slightly in his seat, eyes locking onto Velzard with an unsettling intensity.

"I have been watching you for quite some time now, Velzard."

The way he said her name sent a shiver down her spine. It wasn't possessive or threatening. It was something more subtle, more intriguing. He seemed to see her in a way no one ever had—completely.

His golden eyes never left hers, piercing, reading every unspoken thought, every hesitation in her expression.

"You've picked my interest," he continued, his voice smooth like silk. "So, Velzard… what will you do now? Will you stay here, waiting for Guy to resurrect? Or will you come with me?"

Velzard's mind felt overloaded with questions.

The years of following her brother's will, the endless days spent in loyalty to Veldanava, now felt like a distant memory.

The world felt shifting, and everything was beginning to tilt in ways she had never expected. Arion, this enigmatic being, who claimed to be Veldanava's successor, had shown a strength and charisma that was undeniable. She could feel his power—it was palpable, like an unspoken promise of something far greater.

But could she trust him?

Was his path the right one?

Her eyes flickered briefly towards the horizon, as if she were searching for something, perhaps an answer to the turbulence in her soul.

She had always been loyal to her brother, Veldanava, the Creator, but now, that loyalty felt fragile—as if it was no longer grounded in anything solid. The world had changed.

She thought for a moment, then glanced back at Arion, her face softening, but her eyes still sharp with discernment.

"I will follow you," Velzard said, her voice steady and confident, though it carried a hint of uncertainty—the last vestige of her doubt.

"To make sure you stay on the right path."

Velzard's decision surprised even herself. The weight of it was heavy, but there was something about Arion that demanded it—something about his absolute presence that made her feel like it was the only possible choice.

"And if what you're saying is true—that you are my brother's successor," she continued, "then it is my duty to help you."

Arion's expression softened for just a moment. There was no arrogance in his smile now, only the warmth of someone who knew they had just gained an ally—someone who would walk with them through the uncertainties to come.

Velzard stood still as Arion extended his hand, his golden eyes glinting with an unreadable expression. She hesitated for only a moment before taking it. The moment her fingers brushed against his, the world around them began to blur, dissolving into light.

When the light faded, Velzard blinked, suddenly finding herself in an unfamiliar landscape. She could feel the strange energy surrounding her, a hum vibrating in the air.

"This place..." Velzard murmured, taking in the sight of the city in front of them. The towering buildings stretched high, each crafted with a unique architectural style, modern yet timeless, like a living, breathing entity. The streets were bustling with life—strong demons walking in every direction, conversations drifting in the air, and even the faint scent of food from nearby restaurants.

There was even amusement to be found, vibrant lights flickering in the distance, but there was something more—something alive in the very essence of the city.

Arion smirked as he watched Velzard take it all in.

"Impressive, isn't it? Welcome to the City of Eternal Nights, hidden deep in the Jura Forest," he said, his voice calm but filled with quiet pride. "It's a place where time shifts constantly. It evolves with the needs of those who live here."

Velzard's eyes narrowed in curiosity, stepping forward to take in the sights more closely. "I never imagined something like this existed… How can a city like this exist so secretly?"

"Ah," Arion's smile grew more mysterious. "That's one of its secrets. The city changes with the flow of time itself. The people here are constantly shaping it, as are the forces that govern this place."

Velzard was silent for a moment, processing the information, but her attention was drawn to something else.

As they walked deeper into the city, Velzard could feel the eyes of the Primordials upon her. There was a sudden shift in the atmosphere, a power that made the air heavy and thick. As she looked up, she saw them—Diablo, Testarossa, Ultima, and Carrera—kneeling before them in perfect unison.

They had appeared so quietly that Velzard hadn't even sensed them approaching. Each of them radiated immense power, their eyes lowered in reverence.

Arion turned to face them, his expression soft but authoritative.

"Rise," he said, his voice steady. The Primordials stood up, their eyes now focused on him.

Testarossa, with her usual composed grace, spoke first. "Master Arion, we welcome you and Velzard to the City of Eternal Nights."

Diablo gave a respectful nod. "We have prepared for your arrival."

Velzard's gaze shifted between the four figures, her mind racing. "You... serve him?" she asked, her tone cautious, though curiosity lingered beneath it.

Arion chuckled softly, turning back to Velzard. "Of course they do. These are my most loyal aides, the ones who keep the city alive and functioning. Diablo, Testarossa, Ultima, and Carrera are all responsible for its growth and protection. And they are here to serve both me and the world I intend to shape."

Velzard couldn't hide the surprise on her face. "They... they are powerful. I can feel their strength, but even more than that, I sense they have an attachment to you. How did you gain such loyalty?"

Arion's smile didn't falter. "By proving I am worthy of it. By showing that I am not only a successor but someone who can reshape everything." His eyes met Velzard's, holding them with a quiet intensity. "And that's why you're here. To witness it."

Velzard felt the weight of his words. Her thoughts turned to her brother, Veldanava, and the path he had left behind. Could this truly be the future of the world? Arion's power, his vision... was it something she could trust?

She blinked, feeling a sudden warmth in her chest. Maybe, just maybe, she was beginning to understand what Arion was truly offering.

"Where do we go from here?" she asked.
