Shadow Born

The Crimson Threshold

The days rolled by quickly at Blackridge Academy. Despite their contrasting personalities, Juno and Jaemin had become an unlikely but inseparable duo. Their bond wasn’t forged by laughter and lighthearted moments, but by shared danger, unspoken truths, and the mutual understanding that neither of them truly fit in with the others.

After school, they trained together in the gymnasium or ventured into low-level dungeons—some registered, some not. Jaemin had a sharp tongue and endless energy. Juno had precision, silence, and purpose. Together, they were a storm.

“Seriously, I should start charging people to watch us work,” Jaemin joked as he sat atop a broken pillar, brushing monster dust off his hoodie.

Juno just nodded, surveying the remains of the dungeon beasts they had dispatched.

But one night, the system intervened.

[System Notice: Solo Mission Assigned] [Objective: Clear Evolving Dungeon (C → B Rank)]

Juno’s brows furrowed. “Solo?”

Jaemin noticed the change. “What’s up?”

“I have to go alone.”

Jaemin’s smirk faltered. “You sure?”

Juno nodded. “System’s orders.”

The dungeon was a suffocating maze of obsidian halls and crimson mist. The mana in the air was dense, oppressive. The creatures here were smarter, faster, and organized like a hive. Juno moved quietly, slaying lower-level beasts, conserving his strength.

Halfway through, the shadows began to whisper—something ancient and powerful lurked ahead.

Then it struck.

The dungeon king emerged—a towering, panther-like creature with obsidian armor plating, fangs like daggers, and molten red eyes that pierced through the gloom.

Juno barely dodged the first strike. The beast’s claw cleaved into the wall behind him, leaving a deep scar in the stone.

He rolled to the side, unsheathing his system blade, and retaliated, slicing across the creature’s leg. But the blade skidded off the armor with a clang.

The king roared, a deep, reverberating sound that shook the ground. It pounced, jaws wide open.

Juno ducked and slashed upward, catching the beast across the chin. It flinched but retaliated by whipping its tail like a spiked mace, sending Juno flying into a column. The impact knocked the wind out of him.

Blood trickled from his nose. His vision blurred.

[Vital Signs Critical] [System Alert: Shadow Energy Unstable]

He coughed, wiping the blood from his face, forcing himself upright.

The system pulsed again.

[Activate Shadow Combat Mode? Y/N]

“Yes,” he hissed.

Black tendrils erupted around him, crawling over his skin like armor. His strength surged, his vision sharpened, and time seemed to slow.

Juno dashed forward, blade glowing with dark energy, and plunged it into the beast’s leg joint—finding a weak spot. The panther screeched and countered with a swipe that tore through Juno’s shoulder.

They exchanged blow for blow. For every strike Juno landed, the beast answered with ferocity. It became a brutal dance—precision versus instinct.

Juno leapt onto its back, stabbing down. The blade punctured the armor slightly—but not deep enough.

The beast thrashed, throwing him off, and he hit the ground hard. His ribs ached, and his limbs trembled. The king charged.

At the last moment, Juno rolled aside and slashed at its exposed underbelly. The blade finally sank deep.

The beast wailed and stumbled, but it wasn’t dead.

Juno summoned his last ounce of strength and vaulted onto the beast’s back again. This time, he drove the blade into the back of its skull.

The dungeon king let out one final, shuddering roar before collapsing.

Juno collapsed too, gasping, body broken but alive.

[Victory: Dungeon King Defeated] [Extract Shadow?]

“Extract.”

A swirling dark mist engulfed the beast’s corpse, pulling at the remnants of its soul. A new shadow emerged—sleek, armored, and snarling at Juno’s side.

[New Shadow Acquired: Obsidian King]

He passed out next to it, exhaustion claiming him.

The next day, Juno was summoned by the guild.

“You’ve been matched with a group for a D-rank dungeon raid,” the coordinator said. “You’ll recognize someone in the party.”

Juno turned to find Jaemin leaning against the wall, sipping a smoothie.

“Told you I’d be back.”

The party consisted of six hunters: Juno, Jaemin, and four others—two swordsmen, a healer, and a scout.

The scout, a short girl with bright copper hair and hawk-like eyes, stepped forward.

“Hanni. New to the guild but not new to surviving,” she said confidently.

Jaemin leaned toward Juno. “She’s sassy. I like her.”

The team entered the dungeon, a labyrinthine structure filled with traps, illusions, and beast-infested halls. Juno and Jaemin moved as a unit, their synergy unmistakable.

In one encounter, a beast lunged from the ceiling—Hanni’s quick reflexes saved Jaemin’s life.

“Watch the ceilings, smoothie boy,” she quipped.

“Rude,” Jaemin said, “but fair.”

They continued deeper into the dungeon, their movements sharper, their roles clearer.

As they reached the boss chamber, the air thickened. The dungeon king emerged—a centipede-like creature with steel plating and bladed limbs.

Juno’s eyes narrowed. He summoned the Obsidian King. The shadow beast leapt into action, drawing attention while Juno and Jaemin coordinated the final blow. Hanni supported from the rear, slinging blades at the creature’s weak spots.

Together, they triumphed.

[System Notice: Party Victory | New Bond Formed: Hanni]

As they exited the dungeon, bloodied but victorious, Hanni looked at the boys and smirked.

“You two are something else,” she said.

“Tell me something I don’t know,” Jaemin replied.

Juno glanced at Hanni, nodding once.

A new ally had joined the shadows.

Juno stood still, his breath shallow, the soft hum of the system vibrating through his bones. [System Mission Assigned: Solo Dungeon—B-Rank. Accept or Forfeit. Penalty for Refusal: Vitality Drain 10% daily.]

He had barely recovered from the last raid with Jaemin and Hanni. The weight of the sword he recently purchased from the system still felt foreign in his hand. Yet the moment he clicked “Accept,” the world twisted again, and he was swallowed into darkness.

The dungeon felt wrong. The air reeked of dried blood and rusted metal. The walls of the cave pulsed like a living being, veins of glowing red tracing along the walls. Juno activated his system vision and watched as several heat signatures scattered in the distance.

"Shadows... stay alert."

His voice echoed low, and two shadows responded—ghostly specters in humanoid forms. They were from his previous kills, but he hadn’t yet mastered commanding them.

A beast charged—a grotesque panther with bone spikes and three red eyes. Juno dodged, barely. The system chimed:

[Stat Check: Agility too low to dodge effectively. Recommended: Strengthen physique.]

“No time for lectures.”

The beast pounced again, catching Juno by the side. Pain flared, his ribs cracking. Blood pooled at his lips. He screamed and countered, slicing upward as his shadow moved with him—one distracting, the other stabbing.

He barely survived wave after wave of beasts. Bones cracked, tendons tore, his stamina bar dipped into red. Finally, at the heart of the dungeon, the King emerged.

A ten-foot monster made entirely of molten stone and ash with magma running like veins across its arms. [Dungeon King: Vulkaros. Rank: B+.]

“System, I need backup.”

[You are alone. Adapt. Or die.]

The ground ruptured beneath Vulkaros’s roar. Juno summoned both shadows again, each charged. He activated his new skill: [Shadow Surge]—temporary enhancement of all shadow abilities for 60 seconds.

The battle raged. His blade shattered halfway through. Vulkaros slammed him into a wall. Juno coughed blood and spit out a tooth. The system activated emergency life support.

[Auto-Regeneration: Activated. Shadow Pool Consumed: 50%.]

The pain didn’t stop. Vulkaros summoned molten spears. Juno barely rolled away. Fire scorched his legs.

His vision blurred.

“No... I won’t die. Not again!”

With a roar, he surged forward, shadows mimicking his motion. The shadows held Vulkaros’s limbs briefly—just long enough. Juno vaulted off a boulder and drove the broken blade hilt-first into Vulkaros’s molten skull.

Silence.

Then:

[Victory. Dungeon King Slain. Level Up x2.]

[Shadow Extraction Possible. Proceed?]

He stabbed his hand into the molten remains. “Extract.”

The shadow twisted, rippling out. The shape of Vulkaros rose behind him—tall, burning eyes replaced with empty voids. It bowed before him.

Juno collapsed.

When he woke up, Jaemin was leaning against the hospital doorframe with arms folded and a dangerous smirk.

“Yo. You nearly died. Again.”

Juno blinked. “How—how did you even know I was—”

“I have my ways.”

Something changed in Jaemin’s gaze. It wasn’t playful this time.

“You ever wonder how I joined that last raid?” Jaemin asked, tossing Juno an energy drink.

Juno frowned. “You said you were applying to my school.”

Jaemin shrugged. “That wasn’t a lie. But I also didn’t say that my dad is Han Jaewon. You know… the guildmaster of the Silver Fangs.”

Juno froze.

“You’re… the heir to one of the five major guilds?”

Jaemin chuckled. “Yeah. I didn’t want to say anything. I wanted to see if you’d treat me differently. Guess what? You didn’t.”

Juno’s hands clenched. “Why tell me now?”

Jaemin’s smile faded. “Because I saw what you did. I know you’re different. The others forgot the raid… I didn’t. I saw you command shadows. I saw you change.”

Juno stood slowly. “So what now?”

“Now,” Jaemin said, leaning in, “we keep secrets. Yours. Mine. We’re in this together.”

Two days later, a formal invitation arrived.

[International Guild Mission: Gate Activity Detected in Belgium. High-priority team requested. Assigned: Juno (Rank E+), Jaemin (Rank B), Hanni (Rank C). Mission: Scouting and First Contact.]

Juno looked at the envelope, then at his system notifications.

[Special Reward Unlocked: Guild Compatibility Boost. New Weapon Shop Tier Available.]

He grinned slightly. “Looks like the world’s finally noticing.”

Jaemin popped his head into the room. “Ready for Europe?”

Hanni followed, polishing her dual daggers. “Hope you boys can keep up.”

Juno’s eyes burned with purple light. “Let’s go.”
