Tokyo is a city that never sleeps. Bright lights flicker through the night, reflecting off the wet pavement from a constant drizzle. Skyscrapers tower as if trying to pierce the sky, creating a majestic yet cold view. Beneath this glittering surface lies a hidden darkness, a world unseen by ordinary people. A place where laws hold no power, where strength, intrigue, and lives taken without mercy define authority.

At the top of one of the tallest buildings, a man stands watching the bustling city far below. His face is hidden behind a black mask, leaving only a pair of sharp, empty eyes visible. He is a shadow moving between light and darkness, known only by the name Raven. In Tokyo's criminal underworld, Raven is not just an ordinary person he's a legend, a hitman who never fails to complete his assignments.

Tonight, his mission is to eliminate a businessman who has played with fire for too long with the city's biggest crime organization. His target is a powerful man living in luxury on the top floor of an elite building, surrounded by wealth and tight security. But to Raven, these are merely minor obstacles he's used to overcoming. He's never failed a mission, and tonight will be no different.

Raven takes a deep breath, savoring the cold night air before leaping off the rooftop. His body cuts through the wind swiftly and silently, like an owl hunting prey in the darkness. With perfect precision, he lands on the balcony of the adjacent building without making a sound. The balcony overlooks a living room with large glass walls, offering a wide view of the city below. The view is beautiful, but to Raven, it's just a backdrop for his performance. His focus is solely on one thing eliminating his target quickly and cleanly.

Inside, the room is adorned with expensive artwork, and the floor is covered in thick carpet that muffles footsteps. In the center of the room, a heavyset man in an expensive suit sits on a sofa, a glass of red wine in hand as he talks casually on the phone. The man is completely unaware that his death is just a few steps away.

Raven moves slowly toward the security panel that controls the glass door. With practiced motions, he connects a small wire to the panel and enters a code known to only a select few. Within seconds, the security system is disabled, and the glass door opens quietly. Raven enters without a sound, like a shadow undetectable to the naked eye. Every movement is filled with caution, every step meticulously planned.

But as he draws closer to his target, a strange feeling creeps into his mind. The room feels too quiet, too orderly. Instincts honed over years as an assassin give him a bad premonition. His eyes scan the room, searching for anything out of place. And there it is a tiny flash of red light in the corners of the room. Hidden cameras, more than what would typically be installed in a place like this. Realizing something is wrong, Raven presses himself against the wall, but it's already too late.

Suddenly, alarms blare loudly, shattering the silence. Red lights flash from the ceiling, signaling that a trap has been sprung. His target turns with a smug smile, setting down his wine glass and speaking with a voice full of triumph.

"I've been expecting you, Raven," the man says through hidden speakers in the room. His tone drips with mockery, as if he's relishing the suffering he's about to inflict on the assassin who has taken too many lives.

Raven wastes no time. He leaps behind a large sofa, shielding himself from a hail of bullets suddenly fired at him from the door, which bursts open with armed guards. They enter swiftly and in formation, each wielding automatic weapons, ready to unleash a relentless barrage. But Raven is not an easy target. Moving with agility, he draws two silenced pistols from under his jacket and begins returning fire with deadly accuracy. Every bullet he fires finds its mark, hitting the guards right between the eyes.

Despite Raven's lethal counterattack, the number of enemies keeps increasing. More guards flood in from the corridor, filling the room with gunfire and shouts. But Raven does not relent. His body moves like a deadly dance, scaling walls, leaping from one spot to another, dodging bullets while methodically targeting each enemy. Every time he closes in on a guard, his blade flashes swiftly, striking the throat or heart with a smooth, clean motion.

The rain outside intensifies, as if joining the chaos unfolding inside the room. The large windows that once offered a stunning view of Tokyo are now cracked and shattered by gunfire, letting in cold night air mixed with the smell of gunpowder and blood. But none of this distracts Raven. He's accustomed to scenes of destruction like this. For him, this is just another day on the job.

Yet, in the midst of the battle, fatigue begins to set in. Minor wounds start to accumulate gunshot grazes on his arms, cuts on his face, bruises from small grenade blasts used by his enemies. Although Raven remains composed, he knows the situation is getting worse. There are too many enemies, and they all seem to know exactly how to counter his moves.

"This is too well-planned," Raven thinks as he analyzes the situation. "They were waiting for me. Someone leaked this plan."

But there's no time to ponder the possibility of betrayal. Raven's focus is on one thing completing his mission and getting out alive. He sees his target trembling behind a large desk, trying to shield himself from the chaos. The once confident face now shows fear. He knows that this defense may not be enough to stop the assassin standing before him.

But before Raven could get closer, the large door at the back of the room swung open, and a massive figure entered. A giant man, dressed entirely in black with lightweight armor, wielding a large automatic weapon. This man wasn't an ordinary guard he was clearly a professional, likely another hired assassin brought in to ensure Raven wouldn't leave this place alive. His gaze was cold, filled with complex hatred. Two predators stood facing each other, knowing only one would walk away victorious.

Raven took a deep breath, gritting his teeth against the pain from wounds that were becoming increasingly unbearable. He knew this fight would determine his fate. Quickly, he pulled a small grenade from his belt and tossed it at the giant man. The explosion shook the room, shattering the remaining glass. The sound of the blast was followed by the crackling of broken glass falling to the floor, cold wind rushing in, and the roar of the rain growing louder.

Amidst the smoke and shards of flying glass, Raven moved swiftly. He leaped toward his target, who was hiding behind a desk, determined to finish the job. With a steady hand, he aimed his pistol at the man's head, catching a glimpse of the fear in his eyes before pulling the trigger. The bullet shot out quickly, striking the man's skull, ending his life instantly.

However, the victory was fleeting. Raven's body jerked back as bullets from the automatic weapon tore into him. Excruciating pain radiated from the wounds across his body. Blood flowed profusely from his injuries, staining the luxurious carpet beneath him with deep red. His breathing grew ragged, vision blurry, yet he showed no fear. Even on the brink of death, his sharp eyes remained focused on the large man approaching with heavy steps, weapon still poised to finish him off.

Raven knew this was an inevitable end. His body had reached its limit. Every muscle felt weak, and a cold sensation began creeping through his veins. But he had never learned to surrender. With the last bit of strength he had, he tried to rise, clenching his teeth against the searing pain. The large man stopped a few steps away, looking down at Raven with a disdainful gaze.

"So this is how a legend ends?" the man said, raising his weapon for the final shot.

Raven didn't respond. He simply gave a faint smile, blood seeping from the corner of his mouth. To him, death was merely the end of one journey leading to another. His life had been filled with blood and death, and if this was the end, he would accept it with his head held high. Yet, before the trigger could be pulled, something strange happened.

The world around Raven suddenly felt different. The sound of rain, the clinking of shattered glass, and the heavy breathing of his enemy began to fade away, replaced by a deep and eerie silence. Darkness crept in from the corners of the room, swallowing every bit of light. The pain that had dominated Raven's body started to fade, replaced by a cool, soothing emptiness. He felt his body growing lighter, as if being drawn out of this world.

Then, a foreign voice echoed, like a whisper coming from every direction, yet not from any human mouth. The voice was deep, authoritative, yet strangely inviting.

"It is not your time to rest... Your time is not over yet."

Raven tried to comprehend what was happening, but his consciousness slowly slipped into darkness. He felt like he was floating in an endless void, falling into nothingness. Yet, despite losing control, his awareness remained, trapped in shadows that continued to engulf his mind.

The darkness wasn't just empty but filled with something indescribable—as if thousands of eyes were watching him from behind a black curtain. The whispering voice returned, this time clearer, as if speaking directly within his mind.

"Rise, incomplete being... You will receive a new life, one more suited to your purpose."

Flashes of images started appearing in his mind. Cities crumbling, strange creatures he had never seen before, a world filled with magic and powers beyond human imagination. But it all felt foreign, disconnected from the reality he knew. In the midst of this void, a transparent window suddenly appeared before him, floating in the darkness.

...[System Initialization]...

...[Entity: Undefined]...

...[Fusion Process Commencing]...

The window looked like a computer interface, something familiar to Raven from his old life. But before he could process what was happening, his body felt like it was being squeezed by an immense force, as if pushed through a narrow crack in space and time.

Suddenly, a bone-chilling cold greeted him. He was no longer floating in emptiness but somewhere real. Yet his body was no longer as it was before. Raven's consciousness awakened inside a completely different form. He no longer felt tied to flesh and bone. Instead, he was something smaller, more fluid... and far more dangerous.

He had become a virus, a tiny entity capable of infiltrating and infecting anything. His consciousness flowed within this form, sensing every molecule, every minute movement penetrating the cells of his host. At first, confusion overwhelmed him. How could an assassin transform into something like this? But amidst the confusion, a new awareness dawned a realization of incredible potential.

The system that had appeared earlier re-emerged in his mind, now more complete.

...[Name: Undefined]...

...[Entity: Primordial Virus]...

...[Initial Skills: Infection, Replication, Skill Copying]...

...[Status: Development Stage]...

Raven or now more accurately, the viral entity felt a surge of information flowing into his consciousness. His new abilities allowed him to infect hosts, steal their skills, and grow increasingly powerful. This wasn't just a rebirth this was an opportunity to become something more than human.

Yet there was something more than mere survival in this form. A mission was etched into his mind, as if commanded by the force that had given him this new life.

"I will conquer this world... And this time, I am no longer bound by morality, limitations, or humanity," he thought with newfound determination.

In a world full of magic and strange creatures, his new power was not something to be underestimated. With every host he infected, he could become stronger, smarter, and deadlier. And behind every move, there was a system constantly guiding him, offering missions and rewards, as if he were playing a game designed to make him even more formidable.

In the wilderness where he was first reborn, a gentle breeze rustled through the fallen leaves and damp earth. No one knew that among the decaying foliage, a new threat had emerged not from man, not from ordinary life, but from something far more lethal.

Raven's new adventure had begun, no longer as a hitman in the human world, but as a virus bringing devastation to a world filled with fantasy. In this world, he would no longer fight with bullets and weapons but with infection and manipulation. And this time, he would start from the bottom, slowly rising until nothing could stop him.
