World had grown up in inhumane conditions, confined since childhood in a cold, metallic room surrounded by steel walls without windows. Scientists entered and exited, some in white lab coats, others with masks, all speaking to him clinically, as if he were nothing more than an experiment. His only memories were saturated with routines of endless tests, pain, and fear.

Day after day, World's mental health deteriorated. He was subjected more frequently to cruel tortures and horrifying scenes: forced to witness animal executions, scenes that would haunt most people. And always, they repeated the same phrase: this was real life. If he wished to "awaken," he had to accept it.

But World had one thought repeating in his mind: "What a load of crap."

Among the scientists, one stood out. Her name was Yui. Unlike the others, she seemed gentle and compassionate, always there to ease World's pain after his torture sessions. She would come to bandage his wounds, whispering comforting words. To him, she was the only light in this dark and cruel world.

One day, however, everything changed. Bound as usual, World expected to see another animal suffer before him. But this time, a man was brought before him. The scene unfolded in chilling silence. They tortured him, executing him with inhuman coldness, then approached World, showing him the severed head up close.

Something shattered inside him. Faced with this horrific vision, the emotional shock filled his mind, plunging his gaze into emptiness. But this emptiness only gave way to a burning, immeasurable rage he had never felt before. He felt a new energy rising in his body, a latent power boiling within, threatening to explode.

And for the first time... World broke the chains holding him.

Anger was etched on World's face, black with rage, his eyes emptied of humanity. The feeling of powerlessness had transformed into an untamable fury. He focused on the first scientist in his view, a man with thick glasses frozen in fear. In an uncontrollable burst, he hurled himself at him, smashing his skull against the glass panel with a deafening crash. Glass shards flew around him, fragments of a reality he no longer wanted to confront. With the sharp fragments in hand, he turned toward the door, an insignificant barrier to his liberation.

With a primal scream, he kicked the door, which shattered with a resounding crash, revealing a hallway bathed in harsh light. A scientist, alerted by the noise, turned and fired without hesitation. But World was faster, slipping behind the man with newfound agility, and snapped his neck with deadly precision. The body fell to the floor in oppressive silence, and the taste of blood in his mouth only heightened his sense of power.

This was just the beginning. World embarked on a true massacre, a macabre dance to the rhythm of terror. The screams of the scientists, who had once been his tormentors, echoed in his mind like a symphony of retribution. Every man, every woman he encountered, he cut down mercilessly. He used whatever he could find: torture instruments, tools, even his own fists, now weapons of destruction. The experimentation chamber, once a symbol of his hell, was now the theater of his liberation.

The hallway, once sterile and cold, gradually turned a dark shade of red. Each life he took fed his rage, transforming his past suffering into an unstoppable force. He felt no pity or remorse. For the first time, he had become the predator. The roles had reversed, and he was no longer the victim at the mercy of his tormentors. In this frenzy, he discovered a poignant truth: suffering could breed unimaginable power.

In a state of frenzy, World moved toward the exit, his hands still stained with the blood of his oppressors. Rage pulsed through his veins like a consuming fire. But as he reached the threshold of freedom, a movement in his peripheral vision stopped him cold. It was Yui, the only person who had shown him kindness, who had cared for him through the worst trials of his life.

In his fury, he saw only an obstacle to his freedom. In a desperate, impulsive act, he turned and stabbed her with a violence he hadn't known he possessed. Time seemed to freeze. Yui's gaze, filled with confusion, quickly shifted to a mix of pain and sadness. Her face, usually gentle, darkened as she collapsed slowly to the ground, shock etched on her features.

Tears began to fill her eyes as she looked at World. His once vacant gaze, now shrouded in rage, gave way to a horrifying realization. He had just wounded the only person who, despite the cruelty of their environment, had always been a glimmer of hope in his life. His heart pounded painfully in his chest as the gravity of his act sank in.

"Why…" Yui murmured, her voice broken by pain. Each word felt like a dagger in World's soul. She raised a trembling hand, gently touching his bloodstained cheek, a surprising tenderness in such a tragic moment. "World, I wanted to help you… I wanted… you to find peace."

At that moment, the world around him faded, leaving only the palpable suffering of his pain. He was lost, trapped in a whirlwind of contradictory emotions. Yui, in her final breath, spoke words that echoed like a death knell in his mind. "The man behind your suffering is Lennard."

These words clung to his mind, and a deeper, more profound rage began to stir. Who was Lennard? Why was he tied to his suffering? Yui closed her eyes slowly, her breath fading, leaving behind an immense void. The warmth of her body vanished, and the room, already marked by death, seemed even colder.

World fell to his knees, his rage mingling with unbearable sorrow. Every moment of pain he had endured, every torture, every humiliation, now weighed on his heart. He had killed the only person who had dared to treat him with compassion. A horrifying reality filled him, consuming him with despair.

With the last spark of hope extinguished within him, he swore to uncover the truth behind Lennard. That name, now etched into his mind, became a promise of vengeance. World rose, tears streaming down his face, marked by the weight of his actions. The path of redemption and revenge lay before him, and he knew he would not turn back. He would bear the burden of his deeds, but he would do everything to make the name Lennard synonymous with fear and suffering.

Taking a moment, World explored the laboratory, a place that had been the backdrop to his suffering for so long. Every corner, every instrument, every room held memories of his despair. But now, with rage boiling within him, he no longer saw this lab as a prison; it was a battlefield where he would exact his revenge.

His hands, still trembling from the adrenaline of the massacre, ran over the cold surfaces of metal tables. At the back of the room, he discovered a concealed compartment containing neatly stored explosives. A gleam of excitement crossed his eyes, and a sinister smile spread across his lips. The tools of his liberation and revenge were right there within reach. With meticulous precision, he placed the explosives in strategic corners of the lab, a tribute to the destruction of his former world.

Once the task was complete, he walked out slowly, heart pounding, a mix of adrenaline and anticipation pulsing in his veins. His hands were shoved in his pockets, his bare torso stained with the blood of scientists, revealing a body sculpted by pain and survival. Every drop of blood on his skin told a story, a tale of suffering, rage, and now freedom.

He walked quietly through the corridor, his footsteps echoing like a funeral march. With each step, he shed a piece of his past. The walls, once witnesses to his distress, seemed to fade behind him as he moved toward the outside world, toward the light waiting for him.

Behind him, the lab began to tremble, then an explosion shattered the silence. The walls shook, and a shockwave slowed him briefly before a deafening detonation followed. The sound resonated like a symphony of destruction, a liberation hymn marking the end of his nightmare. Shards of glass and metal fragments flew in all directions, illuminating the dark sky with sparks of light.

World did not look back. He knew each explosion confirmed his victory over his former oppressors. His gaze empty yet resolute, he continued forward, his heart beating to the rhythm of his new destiny. When he finally reached the outside, he stopped. He stood there, feet firmly planted on the ground, as the dust slowly settled around him.

For the first time, he looked up at the sky. A vast blue canvas stretched above him, dotted with brilliantly white clouds. The sun, bright and warm, bathed him in golden light, washing away the shadow of the lab. It was a sight that moved him. He had lived so long confined, in the shadow of terror, that he had forgotten the beauty of the outside world.

Standing on solid ground, a new life began. Tears of rage and pain mixed with those of joy and relief. Yui's memory, her sacrifice, and her final message resonated within him as a call for vengeance. He knew he would carry her memory in his heart, an eternal flame guiding him on his path.

World closed his eyes for a moment, taking in the fresh, pure air, promising himself never to return to darkness. This chapter of his life was closed, and another opened, full of promises and dangers. With renewed determination, he moved toward the horizon, ready to face the world waiting for him, determined to uncover the truth about Lennard and to transform his pain into strength.
