Dawn came cold over Outer Ruin Sector 9.
The transport platform overlooked a dead stretch of broken road, collapsed towers, and jagged stone ridges that looked like giant claws ripping out of the earth. Beyond them sat the mission zone—a low-sinking industrial ruin swallowed by ash, rust, and old beast tracks. Wind moved through cracked structures with a hollow whistle that made the whole sector sound empty.
It wasn't.
Xairen knew that the moment he stepped off the transport.
A mission officer in a dark field coat stood by a floating display board, calling names while four candidates waited nearby with travel gear, sealed weapons, and expressions that already said enough.
They were all young.
They were all ahead of him.
And they all knew exactly who he was.
"Provisional Field Team Seven," the officer said. "You move in, locate the nest, clear hostile presence, confirm no deeper corruption, and return before sunset."
His eyes shifted to Xairen for half a second too long.
"No hero behavior. This is a field evaluation, not a stage."
The tallest one in the group let out a dry laugh.
That was Daigo Kuren—the broad-shouldered red-haired candidate from the arena. Heavy gauntlets. Heavy stare. Built like somebody who solved most problems by hitting through them.
"Funny," Daigo muttered. "That advice came a little late for him."
A girl standing beside him adjusted the straps on her twin blades without looking up.
Renka Tsukishiro.
Calm face. Focused eyes. No wasted movement anywhere.
On the other side of the squad stood a slim girl with short dark hair, a data wrap around one forearm, and a colder, more tactical expression. Shiori Amagane barely glanced at Xairen before going back to the mission file projected above her wrist.
The fourth was Jin Arakiba, the youngest-looking of the group. Spear user. Nervous shoulders. Trying to look tougher than he felt.
The officer finished the briefing and dismissed them.
No speech. No comfort.
Just a mission.
That was the world.
As the transport lifted back into the pale morning sky, silence sat over the team for a few steps until Daigo finally broke it.
"Level?"
He didn't say it like a question. He said it like a challenge.
"Two," Xairen answered.
Jin nearly choked. "You're only Level 2?"
Daigo gave a humorless grin. "Told you. One arena kill and everybody loses their mind."
Renka kept walking. "He still got the kill."
"That was an accident inside a sealed test," Daigo shot back. "This is a real mission."
Xairen said nothing.
Because Daigo wasn't fully wrong.
The mission tracker on Shiori's forearm lit up.
BEAST NEST CLEANUP
Recommended Range: Levels 4–8
Team Average: 6.2
Xairen Kurogami: Lowest Level in Unit
Jin winced when he saw it.
Shiori finally spoke. "You're dragging our average down."
Xairen looked at the broken skyline ahead. "Then don't let me."
That got Renka's attention for the first time.
They moved through the outer ruins in formation. Daigo at point. Renka floating between front and flank like a blade waiting to be drawn. Shiori in back-center tracking movement patterns. Jin guarding the rear, trying to keep his spear steady.
Xairen was placed off-angle.
Not trusted enough for the core line. Not weak enough to babysit.
The message was clear.
Earn your space.
The first beasts came twenty minutes later.
Three of them dropped from a collapsed overpass—long-limbed scavenger creatures with bone ridges along their backs and split jaws that opened too wide. Standard ruin beasts. Fast. Pack-minded. Not titan blood, but still dangerous for undisciplined fighters.
Daigo moved first with explosive force, smashing one sideways with a gauntlet strike so hard it broke against a concrete wall. Renka blurred through the second in a silver flash, both blades cutting clean in an X across its throat.
The third came low toward Jin.
He panicked for half a step.
Xairen was already moving.
The chain axe snapped into his hand in a compact smoky form, smaller than the version from the arena but still ugly, heavy, alive. He whipped it once. The chain hissed forward, wrapped the beast's forelimb, and yanked it off line before it could hit Jin. Xairen stepped in, pivoted with the pull, and buried the axe edge into the side of its skull.
The body hit the ground hard.
A chime sounded in his head.
RUIN SCAVENGER ELIMINATED
EXP GAINED: 18
Small.
But real.
Jin stared. "You summoned that way faster than yesterday."
"Because yesterday almost killed me," Xairen said.
Daigo snorted, but didn't argue.
They kept going.
By midday, the mission had already become more valuable than the briefing suggested. The nest was bigger than expected, with multiple collapsed chambers under the industrial sector and signs of repeated migration. Dead beasts. Fresh claw marks. Bones stripped too clean.
Shiori crouched near a fractured tunnel entrance, studying the residue.
"This is wrong," she said.
Renka's hand moved to one blade. "Corruption?"
"Not full corruption." Shiori touched a black smear along the stone. "Something pushed these beasts out of their normal pattern. Too much nesting pressure. Too much aggression."
Daigo cracked his neck. "So we clear deeper."
Xairen looked into the tunnel.
The air coming out was warmer than it should've been.
And heavier.
That same invisible tightness brushed the skin along his weapon arm.
His Black Mark didn't ignite, but it stirred.
He felt it.
Shiori noticed him noticing. "What?"
"Something in there."
Daigo folded his arms. "Yeah. The nest."
"No," Xairen said. "Something else."
For the first time, nobody laughed.
The team descended.
The lower chambers were tighter, darker, and louder with distant scratching. Beast eyes flashed in pockets through the dark before vanishing. Pipes ran along the walls like dead veins. The floor sloped downward into an old loading basin filled with bones, broken crates, and half-eaten carcasses.
Then the whole chamber moved.
Not the floor.
The thing sleeping under it.
A massive beast dragged itself upright from the center of the nest—a plated alpha with iron-colored bone growths, scarred limbs, and a head split by old embedded metal. Its size dwarfed the others they'd fought. Its roar shook dust from the ceiling.
Shiori's face hardened instantly. "That wasn't in the mission file."
Daigo grinned like he'd been waiting for this all day. "Good."
The alpha charged.
Daigo met it head-on, gauntlets slamming into its skull with a shockwave that cracked the ground. Renka flashed left, carving at the exposed joints behind its foreleg. Jin drove his spear into its flank and barely dodged the counter-swipe that shattered a steel support behind him.
Xairen moved with the chain.
He wasn't the strongest here.
Not the most experienced.
Still the lowest level.
But when the alpha reared up to crush Daigo under its weight, Xairen's chain shot around a hanging beam, then snapped across the beast's neck. He used the recoil to launch himself past Renka, swung around the creature's blind side, and buried the axe into a weak seam behind its jaw.
The alpha screamed.
Renka's eyes narrowed.
Daigo roared, drove both gauntlets into its chest, and Jin thrust upward through the softened opening.
The monster convulsed, staggered, then collapsed into the basin in a thunder of bone and metal.
For a second, all five of them just breathed.
Then the system chimed again.
ALPHA NEST LEADER ELIMINATED
TEAM CLEAR BONUS APPLIED
EXP GAINED: 130
Xairen exhaled slowly, smoky axe hanging at his side.
Still behind.
Still climbing.
But now the others had seen something important.
He wasn't just the arena accident.
He could fight.
And deep in the tunnel behind the dead alpha, where the dark dropped farther underground than the mission map had shown, a warm corrupted draft continued to rise.
This mission wasn't over.
Not even close.
