The air inside the dungeon was heavy with the smell of blood and the lingering scent of decay. The silence was unnerving after the violent battle, the only sounds the soft thuds of Renji's breath as he stood over the lifeless body of the tiger monster. Its massive form lay in a pool of its own blood, its chest rising and falling with the final tremors of death, before it stilled entirely.
Renji stood there for a long moment, his gaze fixed on the creature's remains, his chest heaving with exhaustion. His limbs were heavy, his entire body screaming for rest. The battle had taken everything out of him—his strength, his will, even his sanity had been pushed to the edge.
But as he looked at the monster, something else stirred inside him—an unsettling feeling, like a tremor deep within his chest. A strange tugging sensation gripped him, an instinct he couldn't control.
Before he could comprehend what was happening, the energy from the tiger monster surged through him—unbidden, uncontrollable. His skin shivered as the monstrous vitality seeped into his very being, filling the void left by his earlier exhaustion. It wasn't just physical strength—it was something more primal, more feral.
His body responded in ways he couldn't fully process. The changes were subtle at first, but when he looked down at his hands, they trembled slightly, claws twitching as if drawn to something deep within him. The energy of the tiger was now embedded in his cells, like an additional layer of power beneath his skin.
It was more than just an energy transfer. It was an absorption of the very essence of the tiger's abilities—its strength, its speed, its predatory senses. Renji's breath caught in his throat, his pulse quickening as he realized what had just happened. He had absorbed more than just the tiger's physical energy; he had taken its essence into himself.
He didn't want to believe it at first. The thought of becoming even more monstrous, more like the very beasts he hunted, repulsed him. But the surge of power was undeniable. His heart pounded in his chest, and his mind raced as he processed the new energy within him. He had grown stronger. Faster. More dangerous.

"We need to rest," Renji muttered, turning away from the tiger's corpse. His teammates, exhausted and battered, began to gather around, leaning against the walls and taking shelter in the small, dimly lit chamber. Their faces were drawn with fatigue, their eyes hollow from the battle that had just transpired.
Takeshi, though still wincing from the pain in his side, nodded. "We can't push further without getting some rest. That tiger... it was a nightmare. I don't think any of us were prepared for that."
Renji gave a short nod, though his mind was elsewhere. He could feel the new power coursing through his veins, but the last remnants of his humanity still clung to him. He glanced at his team—at Yumi, Takeshi, and Mika—all of them battered from the fight. Their injuries were minor compared to his, but the exhaustion in their eyes was the same.
"We'll rest for an hour," Renji said, his voice low, almost detached. "Everyone heal what you can, and we'll move on."
As they settled, Renji took a seat in the far corner, his eyes scanning the shadows of the dungeon. The energy from the tiger still buzzed beneath his skin, like a constant, pulsing reminder of what he was becoming.

Renji's self-regeneration was unlike anything he had ever experienced. His body seemed to defy the limits of what should have been possible. Where his teammates' wounds took hours—sometimes longer—to heal, his injuries were already closing up within minutes. The deep gashes across his chest, where the tiger's claws had raked through him, were fading as if they had never existed. His body hummed with vitality, the familiar sensation of his accelerated healing rushing through him.
He had always known his mutation was different. It had been years since the initial infection had taken hold of him, but even then, he hadn't fully understood just how much it would alter his physiology. His healing rate was far beyond that of any normal infected. It wasn't just faster—it was almost unnatural, like his body had been designed to withstand and recover from extreme trauma at an accelerated rate.
The energy he had absorbed from the tiger only seemed to amplify this ability. His muscles, once strained and sore, now felt renewed. His bones, cracked and bruised from the earlier blows, were already mending. He flexed his fingers, feeling the strength returning to his limbs.
In just a matter of minutes, the wounds he had sustained from the tiger were barely visible. It was like he had never fought at all. But as his body recovered, Renji couldn't ignore the growing unease inside him. His regeneration wasn't just fast; it was terrifyingly efficient, more so than any infected he had encountered. Was this the price of his mutation? Would he continue to grow stronger, more monstrous, with every battle?
His gaze lingered on his teammates, watching as they fumbled through their own attempts at self-regeneration. Unlike him, their bodies healed at a much slower rate. They were not infected to the degree that Renji was, and it showed.

Yumi, her arm still wrapped in a torn cloth, winced as she tried to push herself to her feet. Her injuries were minor compared to Renji's, but they still left her shaken. The bite marks from the tiger were healing, but it would take hours before they were fully gone. The blood-stained bandages around her arm were slowly turning a darker shade, indicating the slow process of her healing.
"Damn it," she muttered, gritting her teeth. "This is taking too long."
Takeshi, who had been nursing a deep gash on his leg, gave a soft groan as he shifted on the floor. His wound, which had been large and bloody, was now little more than a faded scar, but it would still take some time before he could move freely again.
"It's the damn mutation," Takeshi said, glancing up at Renji. "We're not like you. We'll be out of commission for longer."
Renji gave a quiet nod, the truth of it sinking in as he observed them. They were strong, but not like him. His regeneration was a gift—and a curse. His body healed faster, but at the cost of his humanity. And yet, as his teammates struggled to recover, Renji couldn't shake the feeling of being alone, even amidst the team that had fought beside him.
Mika was sitting against a wall, her head tilted back, eyes closed in rest. Her injuries were deep, but she was managing them as best as she could. However, even her healing wasn't enough to speed the process. It was clear that the group would need more time before they could continue.
Renji knew they couldn't afford to rest for too long. Every minute in this dungeon was a minute closer to the danger that lurked deeper within. But the team needed time, and they weren't going to make it out without some form of recovery.
"We rest until you're ready," Renji said quietly, his voice low as he turned back to the shadows of the dungeon. "But once you're healed, we move fast. I won't wait for any of us to be left behind."
The words were harsh, but Renji knew they were true. They couldn't afford delays. Not in a dungeon like this.
And as he sat there, the energy of the tiger still humming through his veins, he couldn't help but wonder how much longer he could maintain his grip on his humanity before it was overtaken by the beast inside him.

Despite his words, Renji knew rest was an illusion. His body was still, but inside, something stirred—something more insidious than exhaustion. The energy he had absorbed wasn't just making him stronger; it was doing something to him. Changing him.
His fingers twitched involuntarily, the slight prickle of retracting claws making his stomach churn. His senses sharpened in ways that felt unnatural. The darkness around them wasn't just empty shadows anymore—he could hear the faintest rustling, sense the subtle changes in air pressure, even smell the fear and adrenaline lingering in his teammates' sweat.
The tiger's instincts had become his own.
Renji clenched his fists, forcing himself to remain calm. He had been through this before—every absorption brought changes, some minor, some irreversible. The trick was to stay in control. To remain himself.
But what if, one day, he couldn't?
His thoughts were interrupted by a sudden noise—a scuttling, faint but distinct. His head snapped to the side, eyes locking onto a passage in the distance. It was barely a whisper of movement, something even the others hadn't noticed.
Something was watching them.
"Takeshi," he said quietly, his voice steady despite the creeping unease. "You hear that?"
Takeshi looked up, eyes narrowing. He strained to listen, but after a moment, he shook his head. "Nothing."
Renji frowned. He could hear it, clear as day.
Another change.
"Stay on guard," he muttered, his body tense. Whatever lurked in the depths of the dungeon hadn't attacked yet, but that didn't mean it wouldn't. They were vulnerable, and he refused to let them be caught off guard.
Yumi shifted beside him, her breathing slow, controlled. "You sure you're okay?" she asked, studying him carefully. She wasn't stupid—she had noticed something off about him, even if she didn't understand what.
Renji exhaled sharply. "I'm fine." It wasn't entirely a lie, but it wasn't the truth either.
For now, his instincts told him to stay alert. Because if he could feel the dungeon watching him, then that meant one thing:
Something stronger was waiting ahead.

An hour passed in uneasy silence, the only sounds the distant echoes of the labyrinth and the occasional murmurs of his teammates tending to their wounds. Renji stayed awake, unmoving, listening. His body might have recovered, but his mind was far from rested.
Then, the air shifted.
A deep, guttural growl reverberated through the tunnels, low and ominous, vibrating in his bones. This was no ordinary dungeon beast. It was something intelligent. Something aware.
The others jolted upright instantly, weapons at the ready.
"What the hell was that?" Mika whispered, gripping her dagger tightly.
Renji didn't answer. He was already standing, already moving toward the darkness.
The monster had felt him.
It was drawn to him.
And as the shadows twisted, revealing a pair of glowing, inhuman eyes in the distance, Renji finally understood:
The dungeon wasn't just a battlefield.
It was a hunting ground.
And tonight, he wasn't sure if he was the hunter or the prey.
