The laugh echoed through the darkness—a staticky, unnerving sound that belonged to the Shadow Demon alone. As the darkness finally settled, the destruction became clear: windows were either shuttered or shattered, doors hung crooked on broken hinges, and walls bore deep gouges like claw marks. Lights flickered weakly overhead, struggling against the encroaching shadows that seemed almost alive.
In the middle of a pool of writhing, shadowy mass, Sin stood motionless. His red eyes had turned black, leaking wisps of shadow like smoke from dying embers. Shadow armor encased his body in plates that shifted and reformed with each breath. An uncanny smile stretched across his face—too wide, too knowing. This was the Shadow Demon, fully manifested.
The system cascaded with errors, warnings flashing faster than he could process them. Red mixed with black in the notifications, their colors no longer separate but intertwined like poisoned blood. The two system pieces were fusing themselves together, merging in ways that should have been impossible. Usually, red notifications signaled blood, while black ones indicated shadow. But now they merged, their hues weaving together like threads in a dark tapestry, creating something entirely new.
Sin looked down at his hands, his smile faltering for a moment. Something felt different. This wasn't normal. Usually, the transformation would knock him unconscious, sending him back into the mindscape where he and the demon battled for control in an endless struggle. But it looked like he and the Shadow Demon had become one entity. It looked like he had finally seized control instead of being controlled, though the thought brought more uncertainty than triumph.
Shadows writhed around his entire body like living serpents. He raised one hand, testing his newfound power with cautious fascination. With a thought, he created a shadowy blood spike that materialized from the ground, its surface gleaming wetly in the dim light, pulsing with dark energy.
When he spoke, his voice emerged staticky and distorted, layered with multiple tones. "I could get used to this," Sin said, flexing his fingers as dark energy crackled between them like miniature lightning.
But before he could explore his new evolution further, the shadows began to flicker erratically. His eyes shifted from black back to red, the transformation reversing. The smile faltered and died on his lips. His shadowy armor dissolved, and the writhing mass around him absorbed back into his body like water into parched earth. Sin collapsed to the ground, unconscious, his face peaceful despite the chaos surrounding him. Whatever had just happened, it had drained him completely.
**Meanwhile**
A young boy ran through the forest, his breath coming in ragged gasps that tore at his throat. He appeared to be seventeen or eighteen years old, his face pale with exhaustion and fear, sweat streaming down his temples. He carried a young man on his back—Aaron, who had a wooden sword strapped across his shoulders. Aaron was unconscious, barely clinging to life after his encounter with the S-rank demon. His breathing was shallow, each exhale barely audible. Fortunately, the demon hadn't pursued them, though Noah couldn't understand why. Perhaps it had lost interest, or perhaps it was toying with them.
Eventually, Noah spotted a nearby cabin through the trees, its weathered walls a welcome sight. Relief flooded through him as he stumbled toward it, his legs trembling with the effort of each step. He was panting hard when he finally reached the door, his vision swimming. He dropped Aaron as gently as his exhausted arms would allow, and Aaron's wooden sword clattered beside him with a hollow sound.
"Hopefully we lost him," Noah said between gasps, his voice hoarse and cracking. He looked around the forest, scanning the shadows between the trees with wide, fearful eyes. The S-rank demon was nowhere to be found, but that brought little comfort.
"All right, looks like we made it," Noah whispered, wiping sweat from his forehead with a shaking hand. His fingers came away wet and cold. "Now time to find the teleporter and get out of here."
The young man quickly caught his breath, forcing air into his burning lungs. He picked up Aaron, slinging him over his shoulder once more with a grunt of effort. He grabbed the wooden sword with his free hand, its weight familiar and reassuring.
"Maybe try not to rely on your time stop too much," Noah muttered as he carried Aaron inside, pushing the door open with his shoulder. The cabin was small but sturdy, with dust motes dancing in the shafts of light that pierced through the windows. It smelled of old wood and abandonment.
He laid Aaron down on a nearby couch, adjusting his friend's position to make him more comfortable. He positioned Aaron's wooden sword beside him within easy reach. "Just in case you wake up and something happens, you can defend yourself," Noah said softly, though he knew Aaron couldn't hear him. The words were as much for his own comfort as Aaron's.
Now, where was the portal? Noah looked around the cabin, his eyes searching every corner with growing desperation. There was no portal to be found, no telltale shimmer of dimensional energy.
"Come on, come on. Don't tell me someone took it," Noah said frantically as he searched the cabin again, his movements growing more desperate with each pass. His hands trembled as he moved furniture aside, checked behind curtains, peered into dark corners. He had searched nearly five times, checking behind furniture, under tables, in closets—anywhere a portal device might be hidden. Each search yielded nothing.
Eventually, after the fifth round of searching, he gave up, sinking onto a chair with his head in his hands. The teleporter was supposed to be their way back to the Hunter Association. It was how they were supposed to report their findings, how they were supposed to survive. But now they were stuck here, trapped in this dimension with a demon that could kill them without effort.
At first, when Noah realized this, he hadn't been truly affected by it. His mind had been too focused on survival, on getting Aaron to safety. But as he pondered the idea more, the full weight of their situation finally settled on his shoulders like a crushing burden. He would never go back to his friends, never share another laugh with them over training exercises. His family—he would never see them again, never hear his mother's voice or his father's advice. The hunters he had brought with him to this dimension were all dead, killed by the S-rank demon in moments. Their faces flashed through his mind, frozen in their final expressions of terror.
Suddenly, a thought struck him, and with it came a flicker of hope that pushed back the despair. Someone would eventually come to this place via teleporter. They would be saved. People came here to hunt demons all the time, so surely someone would come after them and help. After all, many hunters used portals regularly, and many came to this dimension to hunt demons—either bringing them back dead or alive, or simply returning and leaving the demon corpses in the forest. This was a popular hunting ground.
"Surely someone will come," Noah whispered to himself, clinging to that hope like a lifeline. His voice sounded small in the empty cabin. "Right?"
**In a large building**
A young man stood inside his office, exhaustion etched into every line of his face. Dark circles shadowed his eyes, and his shoulders sagged with weariness. A teleporter sat against the wall beside him, its surface gleaming faintly with residual energy. He was still working at his computer despite not having slept for around two days, sustained only by coffee and determination. He was too consumed by a project he had to complete, his eyes bloodshot and his fingers moving mechanically across the keyboard, typing code he barely registered anymore.
"All right, upload," the man said, clicking the final button with a sense of relief.
The loading bar appeared on screen: 1%... 2%... 3%. It crept forward with agonizing slowness, each percentage point taking what felt like an eternity.
"It's going to take a while for this thing to fully load to one hundred percent," he muttered, rubbing his tired eyes until spots danced in his vision. "So I might as well go to one of the most popular places to hunt demons. Clear my head a bit."
The man stood from his chair, his joints protesting after hours of sitting in the same position. He stretched, feeling his spine crack, then walked toward the teleporter. He began entering the coordinates for Dimension 10, his fingers moving automatically through the familiar sequence. He frowned when nothing appeared on the screen.
"What? It's not showing up." He tried again, carefully typing in the coordinates for Dimension 10, double-checking each digit. Still nothing. "Usually Dimension 10 would have shown up by now, and I could just click it and teleport. But it's not here." He scratched his head, puzzled and slightly annoyed. "Has it been blocked off from this particular portal's access? Maybe if I go to another one, I'll be able to get there."
He walked out of his office, his footsteps echoing in the quiet hallway. Most people had gone home hours ago.
"Ryan, what are you doing out of your office, man?" One of his colleagues approached with a friendly smile, genuine concern in his eyes.
"Tim, what do you mean?" Ryan replied, managing a tired grin despite his exhaustion. "Am I not allowed to walk out of my office?"
Carl—not Tim—just smiled warmly, used to his friend's confusion when sleep-deprived. "Of course you are, but I'm surprised. You haven't left your office in like two days. You haven't hunted demons in like a week. Just trying to make sure you're all right, buddy."
Lucas—not Ryan—smirked, appreciating his friend's concern even as he struggled to remember names correctly. "Yeah, I'm fine. There's a problem with my teleporter. Maybe I lost access or something. I don't know, but I can't seem to access Dimension 10."
Carl looked at him thoughtfully, his expression shifting to one of professional interest. "Dimension 10? Oh yeah, that one." He paused, considering the possibilities, then shrugged. "Look, you can access my teleporter if you want. I'll give you free access—you don't have to pay, you don't have to give me any of your credits. You can just use it for free. If you can't find Dimension 10, it might be blocked off from this brand of teleporters. Just come to my office and we'll see if your teleporter's just broken."
Carl walked his friend down the hallway to his office, which was only a few doors away. He opened the door and gestured inside with a flourish. Multiple computers lined the walls, and several monitors were scattered here and there, displaying various data streams and portal coordinates in shifting patterns of light.
Carl looked at his teleporter and walked over with purpose, his movements confident and practiced. "All right, Dimension 10," he said, beginning to type in the coordinates with quick, efficient keystrokes. Finally, he pushed the enter button and stepped back.
Nothing happened.
"What in the world?" Carl muttered under his breath, his confidence faltering. "I can't find it either." He glanced at Lucas, confusion clouding his features. "I think it might be all teleporters. They might have cut off access to Dimension 10 for some reason. That's unusual."
Then, suddenly, Dimension 10 finally appeared on the screen, the coordinates materializing as if they had been there all along.
"There it is!" Carl exclaimed, relief evident in his voice. "Maybe yours is still loading or something. Could be a system-wide delay." He pressed enter, and a shimmering blue portal opened before them, its surface rippling like water disturbed by an invisible breeze. The air around it hummed with energy.
"All right, see you when you get back," Carl said, clapping Lucas on the shoulder with genuine warmth. "Be careful out there."
Lucas nodded, took a deep breath to steady his nerves and clear his foggy mind, and stepped through the portal. The sensation of dimensional travel washed over him, and everything went blue.
