The Greatest Assassin Gets Reincarnated in Tensura

The clatter of hooves thundered against the dirt track, the scent of sweat and desperation thick in the air. The stadium erupted in cheers and curses, a chaotic symphony of fortune and despair. A young girl, barely ten, sat on a hard, splintered bench, her small fingers curled tightly around the hem of her faded dress. Her dark violet eyes bore into the spectacle before her—not out of fascination, but out of dread.

Beside her, a man gripped his betting slips with trembling hands, his entire body tensed like a coiled spring. He was a wreck of a man—clothes unkempt, eyes bloodshot, the stench of cheap alcohol clinging to him like a second skin.

"Come on… Come on!" he muttered under his breath, his teeth grinding as his chosen horse lagged behind. And then, in one cruel instant, the race ended. His horse did not win.

The slips fluttered to the ground like dead leaves. The man—her father—let out a guttural scream of rage and slammed his fists into the bench, startling Hinata. Without looking at her, he stood and staggered away, pushing through the crowds, muttering to himself.

Hinata knew what this meant.

That night, she and her mother sat in the cold, dark apartment, the single flickering bulb casting long shadows across the peeling wallpaper. Her mother, a frail woman with hollow eyes, sat at the dinner table, staring at the empty plates. There was no dinner tonight. There had not been for days.

Then the door slammed open.

Her father stood there, his breathing ragged, eyes wild with fury. "Where's the money?" he snarled.

Her mother flinched. "I… I don't have anything left."

That was the wrong answer. He lunged at her, gripping her by the hair and yanking her down to the floor. Hinata didn't scream. She didn't cry. She simply watched as he rained blows down upon her mother, who no longer fought back.

That night, as her father passed out in a drunken stupor, Hinata sat in the corner of the room, knees drawn to her chest. Something inside her snapped.

There was no justice. No salvation.

There was only one way out.

The wind howled as the ocean raged below, waves crashing against jagged rocks. The sky was overcast, casting a gray pallor over the world. Hinata's father swayed slightly on the edge of the cliff, his head still fogged with the liquor he had consumed earlier.

"Why the hell did you drag me all the way out here?" he grumbled, rubbing his temples.

Hinata stood behind him, hands clenched into fists. "I wanted to talk."

He snorted. "Talk? What's there to talk about? If you have money, hand it over."

Hinata took a deep breath, then stepped forward. Her voice was calm. "Actually, there's something else."

He turned, an irritated scowl on his face. "What—"

She shoved him.

The moment stretched into eternity. His eyes widened in shock, his arms flailing. He tried to grab onto her, but she took a step back, watching as he tumbled over the edge. His screams were swallowed by the roar of the ocean.

Silence.

Hinata stood there, the wind whipping at her hair. Her heart did not race. Her hands did not shake.

It was done.

Now, all that was left was to claim the life insurance money.

But there was still one more problem.

Her mother did not grieve. Not truly. She sat in a trance, whispering prayers, her fingers clutching onto a worn-out rosary.

"God is watching," she murmured. "He will cleanse our sins."

Hinata narrowed her eyes. "Sins?"

Her mother looked up at her, for the first time in days. There was something different in her gaze—something unhinged. "You think I don't know?" she whispered. "I saw you push him."

For the first time, Hinata felt a pang of unease.

Her mother smiled—an eerie, broken smile. "But it's alright. God will forgive you."

A chill ran down Hinata's spine. She had been careful, meticulous. But if her mother spoke of what she saw…

Her grip tightened around the kitchen knife she had been hiding behind her back.

Just one more. One more and I'll be free.

She took a step forward.

And then—

The world around her warped. A blinding light engulfed her, a powerful force pulling her in.

Hinata barely had time to react before she felt herself being dragged through an unseen abyss. It was as if reality itself had been torn apart, swallowing her whole.

When she opened her eyes, she was no longer in her home.

The air was thick with the scent of damp earth and smoke. Towering trees surrounded her, their branches like skeletal fingers stretching toward the sky.

And then, the voices came.

"Look what we have here, boys."

Three men stepped out from the shadows, their grins predatory.

Hinata's mind snapped into focus. She was in danger. Her instincts screamed at her to move, but her body—frail from years of malnourishment—was slow.

The first man lunged. She barely dodged, stumbling back. The second one swung a blade at her.

And then, something awakened.

A rush of information flooded her mind, calculations forming in an instant. Angles, trajectories—everything became clear.

[Unique Skill: Mathematician] Acquired.

Hinata's eyes sharpened. She ducked, twisted, and grabbed a rock from the ground. In one fluid motion, she hurled it at the man's temple. He collapsed instantly.

The remaining two hesitated.

She felt another shift within her—a dark power bubbling beneath her skin.

[Unique Skill: Usurper] Acquired.

The moment stretched, and then she moved. With newfound strength, she grabbed the fallen man's dagger, twisting it into the stomach of the second attacker. Blood sprayed, his eyes wide in shock as he crumpled.

The last man turned to flee.

Hinata was faster.

With a single, precise strike, she silenced him.

And then, there was only silence.

Hinata stood over the bodies, her chest rising and falling. The scent of blood filled the air. But she did not tremble.

She had been ready to kill her mother that night.

Instead, she had been given a new world to shape in her image.

And this time, she would not be weak.
