Alpha staggered, his once-imposing figure now reduced to a battered wreck. His armor, designed to withstand dungeon-tier devastation, was cracked and seeping energy from the deep gouges Renji had carved into it. His breath came in ragged heaves, the weight of his own failing body dragging him down.
Renji loomed over him, his shadow distorted by the flickering emergency lights. His form was no longer entirely human—his arms lengthened slightly, veins pulsing with a dark, unstable energy. His fingers, now resembling curved talons, flexed as if still hungry for more destruction.
Alpha tried to lift his weapon, but Renji's foot slammed down on it, crushing the reinforced barrel like paper. The suppression team leader looked up, meeting Renji's predatory gaze.
"You were strong," Renji admitted, tilting his head, voice carrying an unsettling mix of admiration and something else—something primal. "But not strong enough."
With one final, decisive motion, Renji's clawed hand plunged into Alpha's chest, gripping his core energy as if it were something tangible. A surge of power exploded through Renji's body, overwhelming his senses with a flood of stolen strength, skills, and knowledge. His mind reeled as Alpha's combat instincts, tactical awareness, and dungeon-honed resilience burned into him.
And then, just like that, Alpha was gone. A hollowed corpse remained, crumbling into nothingness as Renji absorbed everything he was.
For a moment, silence.
Then, the changes began.

Renji staggered forward, clutching his head as unfamiliar memories flashed through his mind. Training regimens, battlefield calculations, strategies meant to counter beings like him—all now his to wield. But more than that, his body was mutating at an alarming rate.
His muscles tightened, their density shifting in ways that felt both exhilarating and horrifying. His skin shimmered momentarily, as if adjusting to newfound resilience. His perception of time sharpened; he could see micro-movements in the air, sense the tremors of distant footfalls. And then there was the raw, unshackled power. His blood boiled with an intensity that made it difficult to breathe.
But something was wrong.
His hands trembled as he examined them. They were changing too fast. The fingers lengthened further before snapping back, as if his body was fighting the transformation. His heartbeat was erratic, a wild rhythm that no longer felt entirely human. It was as though he was standing on the edge of something vast and abyssal, a precipice of power that threatened to consume what little remained of his humanity.
Was this the price of taking from others? Each new ability, each stolen strength, pushed him further from himself. How much longer before Renji Kuroya ceased to exist, leaving only the monster behind?
He clenched his fists. There was no time for fear.

The facility was in chaos. Alarms screamed across the complex, warning of containment failure, but no reinforcements arrived. The soldiers who had once fought with unwavering discipline were now hesitant, their fear palpable. They had seen what had happened to their strongest. They knew what was coming for them.
Renji moved with newfound purpose, his body adjusting to the stolen power as he stalked through the corridors. He no longer needed to rely on brute force alone—Alpha's strategic mind had integrated seamlessly into his own. He saw pathways where before there had only been obstacles. He anticipated enemy movements before they even made them.
A group of desperate soldiers tried to barricade one of the hallways, setting up an ambush with automated turrets. Renji didn't slow. He merely lifted his hand, palm outward, and let the absorbed suppression energy surge. A crackling pulse erupted from his fingers, disrupting every electronic device in a ten-meter radius. The turrets went dead. The soldiers barely had time to react before Renji was among them, striking with lethal precision.
No wasted movement. No unnecessary bloodshed.
Just execution.

The Command Center.
Ahead, reinforced doors loomed—the entrance to the command center. Behind them, Matsuda and the remaining high-ranking officers would be watching, frantically trying to salvage what remained of their operation. Renji could almost hear the tension in the air, feel their desperation.
He exhaled slowly. His grip tightened. There was no turning back now.
With a single step, he prepared to breach the final stronghold.
The endgame had begun.

Renji's Progression
The clang of metal rang through the corridor as Renji's claws scraped the walls. His bloodied and bruised form moved with terrifying purpose, each step heavy with the weight of power he didn't fully understand, but could no longer ignore.
He had defeated Alpha—no small feat—but it came with a cost. With every battle, Renji absorbed more of his enemies' strength, and now that power was pulsing through his veins like wildfire. The S-Class Suppressors, the most formidable foes he had ever faced, had all fallen in the face of his relentless assault, but the true price of their defeat was something Renji hadn't accounted for.
Each of their abilities—the plasma blades, destabilizing pulses, enhanced strength, and tactical awareness—had become his own. They were no longer just the weapons of his enemies; they were a part of him, intertwined with his mutations, amplifying the monstrosity within.
Renji staggered for a moment, his mind racing. The dungeon energy was more than he had ever experienced before. It wasn't just a tool to amplify his abilities—it was consuming him. He felt it gnawing at his thoughts, pulling him deeper into a state where he barely recognized the man he used to be. Was he even human anymore?
A crackling, unstable surge of power shot through him as he moved forward. He clenched his fists, but they weren't just hands anymore. They were weapons—extending claws like blades, each swing capable of cutting through steel. His vision flickered, and the walls seemed to pulse with an unnatural rhythm, reacting to his presence. The dungeon energy was not just something to wield—it was something that connected with him, bending his form and mind, reshaping him.
Renji's senses were heightened beyond comprehension. He could feel the hum of energy beneath the floorboards, the electrical pulses in the walls, the faintest tremors in the distance that signaled the movement of other soldiers. His heightened perception made him feel omnipotent, a predator aware of everything around him, yet it came with a sickening undercurrent of panic. He was losing himself to it. He was becoming the very thing he feared.
The hallway stretched endlessly before him, but he could hear the rapid footsteps of reinforcements closing in. They would be ready. The government wouldn't send anything less than their best to stop him now. Yet, Renji wasn't afraid. He was fueled by a new sensation: power. Raw, untapped power that surged through him like a river breaking through a dam.
He was on the edge of something dangerous, something monstrous. And for the first time in his life, he welcomed it.

Renji rounded a corner and saw the next wave of defenders—a squad of elite soldiers dressed in sleek, black armor, their weapons raised, prepared to neutralize him. There was no hesitation this time. Renji didn't need to plan. His instincts were already guiding him.
The first soldier fired, a barrage of high-caliber rounds tearing through the air. Renji didn't flinch. His body moved before his mind even registered the danger, leaping into the air with inhuman grace. The bullets missed by inches, but the force of their passage left scorched marks in the air, a warning.
He landed behind the squad with a predator's precision, and before they could react, his claws were outstretched. The first soldier dropped without a sound, his throat sliced open in a single fluid motion. The others attempted to turn, but Renji was already upon them, his claws tearing through their armor with ease, skin and metal alike yielding to his ferocity.
In the chaos of the fight, Renji felt something new. He wasn't just defeating these soldiers. He was absorbing their strength—their experience, their training, their weapons. It wasn't a conscious decision. It was an instinctive, almost desperate act of survival.
The first soldier he killed—his enhanced speed and strength were now Renji's. The second—his tactical awareness and precision had merged with Renji's mind, calculating the next move before it was even made. The third—a sniper—had granted him the ability to focus his energy, to heighten his senses to an absurd degree. His next move was no longer dictated by the limitations of the human body. Renji was now faster, stronger, more intuitive.
It wasn't just the physicality of the abilities he was absorbing. It was something deeper—an undercurrent of cold precision that made him feel less human with each passing second. The thirst for power, the need to survive at all costs, was stripping away his connection to his former self. He was no longer Renji Kuroya, the office worker turned rogue. He was a force of nature—a monstrous being who devoured the strengths of his enemies, growing more uncontrollable with each victory.
---
Renji pressed forward, his mind now a chaotic web of absorbed tactics, combat maneuvers, and elemental power. His mutated form had transcended human limitations. He was becoming something else entirely—something far more dangerous.
When the next group of soldiers arrived, Renji didn't even need to think. He dropped to the floor, rolling with unnatural speed and precision. The soldiers, caught off guard, opened fire, but Renji's heightened senses allowed him to dodge the barrage effortlessly. With a flick of his wrist, he summoned an energy pulse from his hand, destabilizing the air around him and disorienting the soldiers.
One soldier, attempting to flank him, found himself struck with a plasma bolt from Renji's fingertips, the energy tearing through his armor with ease. Another tried to engage with a high-frequency blade, but Renji's enhanced reflexes had him countering in a blur, his own claws raking across the soldier's defenses.
The more he fought, the more Renji understood the flow of power. He had become a symphony of destruction—his strikes, his movements, his absorption of power all synchronized into a lethal dance. His opponents were no longer threats; they were mere instruments in his evolution.
But with every fight, Renji's body became more grotesque. His claws grew longer, sharper. His skin, once human, now shimmered with the glow of dungeon energy. His eyes burned with an intensity that bordered on madness. He could hear the thoughts of his enemies, their fear, their realization that they were no longer fighting a man but a monster.

Renji reached the command center—his destination, his goal. He stood before the reinforced doors, his body radiating with the overwhelming power of the abilities he had absorbed. But as he reached out, the familiar tingling sensation of dungeon energy surged through his body, making him pause.
His reflection caught in the metallic surface of the doors. What he saw shocked him. His body was no longer recognizable. The claws, the glowing veins beneath his skin, the inhuman glow in his eyes—all of it made him appear less like the man he once was and more like a creature from the depths of the dungeons he had once feared.
A bitter laugh escaped his lips, but it was hollow, empty. "Is this what I've become?" he muttered to himself.
The door slid open, and Renji's eyes sharpened as he stepped forward into the command center. The remaining soldiers inside paused, looking at the towering figure before them, now far beyond anything they could have anticipated.
The air in the room thickened with tension, and Renji felt a surge of power from within, his body brimming with the energy of countless fallen soldiers. But it wasn't enough. It would never be enough.
He had crossed a threshold now—a point of no return. And though he was stronger than he had ever been, a gnawing fear took root within him. He was losing himself. The power, the strength, it was taking him further and further from the man he used to be. And for the first time in his life, he wasn't sure if he cared anymore.
With a roar that shook the room, Renji advanced toward the remaining forces, his mind fully consumed by the need to conquer, to devour, and to rise higher. There was no going back now.
