The abandoned Shinjuku line subway tunnel lay beneath the city like a forgotten scar. The entrance was sealed years ago—rusted gates chained shut, graffiti covering the concrete. But the chains had been cut. Recently.
Haruto, Miya, and Yuki stood at the top of the cracked stairs leading down. Flashlights cut through the darkness. The air smelled of mold, rust, and something sharper—old blood mixed with Aether.
Miya drew her sword halfway. Blue-white sparks danced along the blade.
"Joker's ping said this is the source. If Nox is forcing Gates, this could be his anchor point."
Yuki formed a thin layer of ice over his fists—protective, ready.
"Or a trap."
Haruto stared into the black.
"It's both."
He stepped down first.
The stairs descended thirty meters. Echoes bounced off the walls—distant drips, faint whispers. The tunnel opened into a wide platform. Trains long gone. Tracks rusted. Pillars cracked.
In the center: a faint purple glow.
A makeshift altar.
Black stone. Carved with runes—identical to the mark on Haruto's palm.
Purple mist rose from it, forming thin tendrils that snaked toward the ceiling.
Haruto's rune burned.
**[System Alert: Resonance detected. Nox Anchor Point. Destroying it will sever one link in the forced Gate network.]**
**[Warning: Guardian entity inbound.]**
The mist coalesced.
A new Echo rose—taller than the last. Nox's silhouette, but twisted further: multiple arms, purple flames coiling like serpents, eyes everywhere.
It spoke—layered voices.
"You brought friends this time. How touching."
Haruto stepped forward.
"They're not here to die for me."
The Echo laughed—Nox's laugh.
"They will. Just like the others."
It attacked.
Purple tendrils lashed out—fast, sharp.
Miya moved first.
**[Lightning Palace – Full Domain (partial activation).]**
Storm clouds gathered in the tunnel ceiling. Bolts chained across the space, striking the tendrils.
They burned, but reformed.
Yuki flanked.
**[Cryogenic Freezing – Wide Area.]**
Ice spread from the floor—locking tendrils in place, slowing the Echo's movements.
The Echo roared.
Multiple arms swung.
Haruto charged.
**[Dragon Variant – Azura Dragon (full partial).]**
Blue scales covered him. Speed blurred. He dodged an arm, leaped onto another, and drove his fist into the Echo's chest.
**[Crimson Flames – Lv.3.]**
Fire exploded inward.
The Echo staggered.
But its eyes focused on Haruto.
"You still carry my mark. You're mine."
The rune on Haruto's palm flared—pain lanced up his arm.
**[HP: 6800/11000]**
**[Debuff: Nox Resonance – 20% reduced stats for 60 seconds.]**
Haruto gritted his teeth.
"No."
He raised his other hand.
**[Tenebrae – Lv.2 (Max Selective Devour).]**
The black sphere formed—huge now, edges razor-sharp.
Miya and Yuki poured power into it—lightning chaining around the darkness, ice reinforcing the core.
The sphere grew.
Haruto hurled it.
It struck the altar.
Darkness exploded.
The purple mist screamed.
The Echo's form cracked—arms dissolving, eyes flickering out.
It reached for Haruto.
"You can't erase—"
The darkness swallowed the words.
The altar shattered.
Purple light died.
The Echo vanished.
Silence.
The tunnel trembled once—then stilled.
**[Anchor Point destroyed.]**
**[Forced Gate network weakened by 8%.]**
**[EXP +3200]**
**[Level Up! Level 11 → Level 13]**
**[New Skill Evolution: Tenebrae → Lv.3 (Void Dominion – partial control over absorbed essences).]**
**[Memory Fragment 4 Unlocked: The Divine Bargain.]**
A brief vision flashed.
The golden light in his dying moments.
The voice—calm, ancient.
"I will give you power. But you will carry the mark. And one day… you will choose."
Haruto blinked it away.
Miya lowered her sword.
"It's gone."
Yuki reformed from ice.
"But it'll come back."
Haruto looked at the shattered altar.
"Not the same way."
He turned to them.
"We cut one thread. There are more."
Miya nodded.
"Then we find them. All of them."
Yuki smirked faintly.
"Team effort, huh?"
Haruto's lips curved—just a little.
"Yeah."
They walked back up the stairs.
The city lights waited above.
But below, in the dark, something watched.
A faint green glow.
Joker's mask—cracked but smiling.
The web tightened.
And the players moved.
