The Greatest Assassin Gets Reincarnated in Tensura

Years passed. The Archdemon remained hidden in the shadows, moving from place to place, growing stronger in secret. He avoided unnecessary confrontations, especially with the other Primordials—not out of fear, but out of strategy. He knew he wasn't ready to face them yet, and he refused to reveal himself before the time was right.

Seated atop a desolate cliff under a starless sky, he gazed into the abyss before him. The wind howled, carrying whispers of distant battles and shifting power. His hunger for growth had not waned. If anything, it had only intensified.

"Lara." His voice was calm but firm, carrying the weight of his ambition. "What is my next evolution? How do I surpass my current self?"

A moment of silence passed as Lara, his ever-loyal analytical system, processed the question. Then, her voice echoed in his mind, smooth and unwavering.

<>

A pause. Then, the answer came.

<>

His crimson eyes flickered with curiosity. "Demon Lord?" He leaned forward slightly. "Explain."

Lara wasted no time.

<>

The Archdemon absorbed every word, his mind already spinning with possibilities. "And how does one become a Demon Lord?"

<> Lara's voice remained methodical. <>

He frowned. Depending on others to acknowledge his power? That was not his way.

<>

His interest piqued. "Go on."

<>

A dark smirk formed on his lips. "So, I must harvest souls… interesting."

Lara continued.

<>

His eyes gleamed with newfound excitement. "Then it's perfect for me."

He leaned back, staring into the vast darkness of the sky. A Demon Lord, huh? A being who can shape the world with their will.

He clenched his fist. "I will do it. I will ascend."

Lara's voice remained steady, but there was a hint of something akin to approval in her tone.

<>

His smirk widened. "I wouldn't have it any other way."

And so, his next goal was set.

Then Lara told him, <>

The Archdemon's crimson eyes gleamed with interest. "Go on."

Lara's voice remained steady and precise. <>

His expression darkened slightly. "A name? Why?"

<>

He exhaled slowly, processing the information. "And who exactly could name me?"

<>

His then remembered Veldora, huh? And where is he?"

<>

His smirk faded slightly. "Why is that?"

<>

His expression sharpened. "Summoned? You mean by a human or some sorcerer?"

<>

He crossed his arms, thinking deeply. "So, I need to find a way to get summoned."

<>

He let out a low chuckle. "How amusing. A being like me, waiting for a human's call."

<>

His crimson eyes glowed with anticipation. "Then all I have to do is wait. When the right moment comes, I will enter that world and claim my place among the strongest."

Lara's final words carried a tone of certainty. <>

His eyes darkened as he recalled the divine being who had granted him this second life. "The God who reincarnated me gave me a mission—to control the Cardinal World and maintain its balance."

Lara processed the revelation instantly. <>

He chuckled. "Of course not. But I was never meant to do it openly. No grand thrones, no banners waving in my name." His voice dropped to a near whisper. "I will rule from the shadows, shaping the world without anyone realizing it."

Lara remained silent for a moment before responding. <>

His smirk widened. "The way of an assassin. I will strike where needed, remove obstacles without leaving a trace, manipulate events from behind the scenes. Kings, nobles, Demon Lords, even gods… none of them will realize the strings I'm pulling until it's too late."

<>

He nodded. "Which is why I need to evolve further. I need more power, more experience, and more connections. Becoming a Demon Lord is just the beginning."

<>

His crimson eyes gleamed with determination. "Exactly. I will become the unseen hand that controls everything."

Lara's voice carried an edge of approval. <>
