Gate Zero

Chapter 3: The Wrong Rodent

Morning light cut through the half-drawn blinds, striping the conference table with thin bars of white. Kang Jisoo stood near the door. He hadn't slept. Inside his jacket, the case file pressed its edges against his ribs through worn lining.

Seo Min-jun occupied the head of the table, unreadable. Pressed suit, cufflinks aligned. The Anchor Core's secured case rested at his elbow; the mana residue fragment sat beside it in its evidence pouch. Neither had shifted since the previous night.

Park Hana entered last and stopped. “What's happening?”

“Waiting,” Min-jun said.

“For what?”

Sirens answered. Not the distant wail from Yongsan—those had droned in the background for two days—but close. Building-front close.

The guild lobby doors slammed open two floors below. Boots on marble. A voice Jisoo didn't recognize barked an order.

Min-jun stayed seated. His silver-gray eyes cut toward the door. “They're early.”

The conference room door swung inward. Three Association enforcers filed through in black tactical gear, mana-suppression bracers glowing faint blue at their wrists. Behind them strode a man in a charcoal suit—investigator's badge on his lapel, hair slicked flat, smile already in place.

Yoon Seok-ho. Association Internal Affairs. The face was familiar from another life; in 2029 this man had personally signed dissolution orders for three mid-tier guilds, every one of them investigating the Circle of Seven.

“Guild Master Seo Min-jun.” Yoon's voice was pleasant. “Apologies for the hour. We have a warrant.”

Min-jun's expression didn't shift. “Grounds.”

“Leaking classified gate data to an unauthorized contractor.” Yoon's gaze slid to Jisoo. “Kang Jisoo. E-rank. Skill: Appraisal, registered as utility-grade F. You're under arrest for violating the Hunter Information Security Act, Article Seventeen, Section Three.”

Hana stepped forward. “That's absurd. He's been inside this building for two days.”

“Which is when the leaks occurred.” Yoon gestured. The enforcers moved.

Two men bracketed Jisoo. One gripped his left arm above the elbow; the other fastened suppression cuffs around his wrists. Cold metal clicked against skin. His mana—what little an E-rank possessed—went quiet.

“I asked for evidence,” Min-jun said, rising.

Yoon produced a tablet. Its screen displayed a data log: timestamped file transfers from a guild-registered terminal to an external server. The terminal ID matched the third-floor conference room.

“These records show classified gate data was accessed and transmitted at two-fourteen this morning. The external recipient is flagged as an unregistered data broker. Kang Jisoo was the only person logged into the guild network at that time.”

“I wasn't on the network.” Jisoo's voice came out flat. “I was in the medical bay. Ask the duty staff.”

“The log shows your hunter ID authentication.” Yoon's smile didn't waver. “This isn't a debate. It's an arrest.”

“Someone spoofed the credentials.” Hana's voice climbed. “That's a setup—”

“Hana.” Min-jun's tone stopped her cold. “Don't.”

She turned. “You can't let them—”

“The warrant is valid.” Min-jun's eyes hadn't left Yoon. “For now.”

Yoon gave a small nod. “Your cooperation is noted, Guild Master. A secondary order has been issued: this guild is sealed pending a full investigation. All personnel are to vacate within the hour. Operations are suspended.”

The enforcer's grip on Jisoo's arm tightened.

Min-jun lifted the Anchor Core's case. A small, deliberate motion. “And this?”

“Association evidence locker. All guild assets are frozen.”

“I see.” He placed the case back on the desk. His expression remained composed, almost bored. “Seems the Association has finally found a mole—unfortunately, it's the wrong rodent.”

No one reacted. Yoon's smile stayed fixed. The enforcers kept their eyes forward. Hana's jaw clenched, but she said nothing.

The case file pressed against Jisoo's ribs. The seven-pointed star burned in his mind.

“Take him,” Yoon said.

The enforcers marched Jisoo out. He glanced back once. Min-jun was already on his phone, dialing with quick, economical movements. The desk lamp flickered. Hana stood frozen, fists at her sides.

Downstairs, the lobby smelled of ozone and old stone. A handful of guild staff clustered near reception, faces pale. Someone had already started packing files into a box.

Outside, gray morning waited. A transport van sat at the curb, rear doors open, two more enforcers flanking it. Across the street a small press contingent had gathered—three reporters, two cameras.

Yoon walked ahead. “Make sure they get the shot.”

The enforcer on Jisoo's right angled him toward the cameras. Flash. Flash again.

He kept his head up. The cuffs bit into his wrists. Then a shove into the van and the doors slammed.

Through tinted glass he watched the guild building recede—reinforced windows dark, lobby emptying. Min-jun hadn't come down.

Eight feet by eight. Gray walls, gray floor, one bench bolted to concrete. A single mana-lamp buzzed overhead. No windows. The air carried the recycled staleness of a system that hadn't been serviced in years.

Jisoo sat. His wrists ached where the cuffs had been before they'd swapped them for a monitoring anklet. The case file was gone—confiscated at processing, locked in an evidence bag with his hunter ID. His jacket hung open; the right cuff was more frayed than it had been that morning, a torn thread catching the lamp's buzz in its vibration.

He'd been here before. Not this cell, not this year. But in the timeline that ended with fire and collapsing gates he'd spent three weeks inside an Association holding facility while the world fell apart. By the time they released him, half of Seoul was gone.

He rubbed his jaw. The scar along it felt tighter than usual.

Footsteps in the corridor. A guard's voice: “Five minutes, Guild Master. Protocol.”

“I recall the protocol.” Min-jun's voice, dry as ever.

The cell door opened.

Min-jun stepped inside, same suit from the morning but tie loosened half an inch—for him, practically undressed. The guard sealed the door and stayed visible through the small observation window.

“Guildmaster privilege,” Min-jun said, as if answering a question. “Provisional clause. It buys me five supervised minutes before the Association director vetoes it.”

Jisoo didn't stand. “They took the file.”

“I assumed.” Min-jun stood in the center of the cell, not leaning. “The embezzlement angle is already in motion. Yoon filed the sealing order too quickly—he left a paper trail. My people are tracing it.”

“Not fast enough.”

A twitch at Min-jun's eye. “Meaning?”

Jisoo looked at the observation window. The guard watched, but the cell wasn't wired for audio; the mana-suppression field scrambled recording devices—the one advantage of being locked in a box designed to neutralize hunters.

“Director Yeom,” Jisoo said, his voice level. “Association Director Yeom will be arrested within twenty-four hours. Embezzlement of gate-clearance funds. The evidence sits in a shell account under his brother-in-law's name. The Hunter Audit Division already has the file—they're just waiting for the right moment to execute.”

Silence stretched.

Min-jun's expression didn't change, but his left hand—the one with the signet ring—went still at his side. “That's a remarkably specific prediction.”

“It's not a prediction.”

“Then what is it.”

Jisoo met his eyes. “Appraisal has layers.”

“Your registered skill is F-grade utility. It reads surface data from monsters and items. It doesn't predict arrests.” Cold precision edged Min-jun's voice. “Try again.”

“No.”

The word landed like a door slamming.

Min-jun stepped closer, the single lamp throwing his shadow across the wall. “You saved Hana from a trap set three days before anyone knew to investigate. You identified the Anchor Core as manufactured before the lab results came back.

You recognized the Circle of Seven's sigil from a file that hasn't been opened in seventeen years. And now you're telling me the Association's director will be arrested tomorrow for a crime that hasn't been publicly charged.“ He paused. ”I don't believe in prophets.“

“Good,” Jisoo said. “Don't start.”

“Then give me something I can verify.”

“Call your contact in the Audit Division. Wait twenty-four hours. If Yeom isn't arrested, I'm wrong and you walk away.” Jisoo leaned back against the concrete; cold seeped through his jacket. “If I'm right, you have a window. Use it.”

“A window for what.”

“The Anchor Core isn't a power source.” Jisoo's voice stayed flat, but his hands tightened on his knees. “It's a disarmament key. The gate-cascade weapon the Circle built—it needs seven Anchor Cores to fire. The one in your vault is the first Core they manufactured. Reverse-engineer it before they secure the other six, and you can shut the whole system down.”

Min-jun stared.

The observation window fogged slightly from the guard's breath.

“You're describing a weapon that doesn't exist,” Min-jun said.

“It exists. It just hasn't fired yet.”

“How do you know.”

Silence.

Min-jun waited. Ten seconds. Twenty. The quiet thickened until the buzzing lamp seemed loud.

“I've answered three questions,” Jisoo said finally. “That's more than you'd get from any asset I've ever run. You want more—verify what I gave you first.”

“That isn't how this works.”

“It is today.”

Min-jun's jaw tightened. The scar across his eyebrow looked pale in the harsh light. Something flickered in his expression—frustration, or the edge of a decision he didn't want to make.

“I could leave you here,” he said. “Let the investigation run its course. You're an E-rank with no guild backing and a suspicious data trail. They'll bury you.”

“Probably.” Jisoo's tone didn't shift. “But you won't. You need the Core's activation sequence. I'm the only one who can read it.”

Another silence, shorter.

Min-jun turned toward the door. “The guard will note this visit as a standard legal consultation. Nothing unusual.”

“I assumed.”

At the door frame his hand paused. He didn't look back. “If Yeom isn't arrested by noon tomorrow, I won't come back.”

“Understood.”

The door opened. The guard stepped aside. Min-jun walked out without another word, footsteps fading down the corridor—measured, even.

The guard glanced in. Jisoo sat exactly as before, hands on his knees, gaze fixed on the far wall. The monitoring anklet blinked green. The observation log, when filed, recorded nothing out of protocol.

The lamp buzzed. Jisoo closed his eyes.

Twenty-four hours. He'd given Min-jun the name, the crime, the window. Whether the guild master used it—whether he trusted it—was out of Jisoo's hands now.

Somewhere above ground, the city kept turning. The Yongsan gate's emergency broadcast looped on public channels. The Association headquarters in Yeouido hummed with meetings and memos and the quiet machinery of a conspiracy seventeen years in the making.

And in a gray cell eight feet square, an E-rank hunter with a worthless skill and a dead man's memories waited for the future to catch up.

The coffee in Min-jun's cup had gone cold hours ago. Dregs left a bitter film on his tongue as he stood before his desk, staring at nothing. Headquarters around him had fallen silent, the last footsteps long faded. Only the single lamp still burned against the deep night pressing at the windows.

Half the lamp's oil was gone. The file lay open where Jisoo had left it, the seven-pointed star still visible on the yellowed page. Hana had moved to the window. Her reflection in the dark glass showed her worrying the strap of her satchel.

Min-jun hadn't sat since they'd closed the file. He stood behind the desk, jacket still on, the silver signet ring catching light as he turned a pen between his fingers.

“Director Yeom,” he said. “Association Finance. He signed off on the original Gwangjin gate budget seventeen years ago.”

Jisoo looked up. “You're sure.”

“The file lists the approval chain. His name is on three separate disbursements for 'containment logistics.'” The pen clattered onto the desk. “A containment that never happened, because the gate was already cleared.”

Hana turned from the window. “Guild Leader-nim, that's—if Director Yeom was involved in covering up the tampering, then he would have access to the medical licensing registry. Healers, potion suppliers, mana-core transport permits. All of it.”

“Exactly.” Min-jun's gaze shifted to her. “You have a Class D medical license. That gives you query access to the Association's health division financials. Cross-reference Yeom's approved disbursements against the registry. Find me a paper trail that doesn't match the official reports.”

Hana's hands stopped fidgeting. “That's a restricted-access query, Guild Leader-nim. If the Association audits the license, I could lose my certification.”

“Yes.”

A beat. Then Hana straightened her shoulders. “What am I looking for specifically?”

“Payments to shell clinics. Supply contracts that loop back to the same three vendors. Anything routed through a medical front that predates the Seoul Accord.” Min-jun pulled a blank card from his desk and wrote a frequency number on it. “When you find it, don't send it through guild channels. This line only.”

Hana took the card. Her fingers trembled once, then steadied. “And if Director Yeom notices the query?”

“He won't.” Min-jun's tone was flat. “He'll be busy.”

The rival faction's intermediary arrived at eleven. Min-jun received him in the ground-floor conference room—no windows, one door, a single recording-suppression field humming from a portable unit on the table. The intermediary was a gaunt man in a gray Association adjudicator's coat, silver trim of a mid-level prosecutor. He didn't sit.

“Guild Leader Seo. You requested a priority channel.”

Min-jun stayed seated. “Director Yeom has been embezzling from the Association's gate-containment fund for over a decade. I have the original approval chain, the altered decay-rate data from Gwangjin, and residue samples linking the tampering to a prohibited sigil. You'll have the financials within the hour.”

No change in the prosecutor's expression. “And you're giving this to my office rather than Internal Affairs because…?”

“Because your faction has been trying to unseat Director Yeom's patron for three years. This puts Yeom in an interrogation room. His patron will distance himself. You get the credit and the vacancy.”

A long pause. The suppression field crackled once.

“What do you want?”

“My guild is under investigation for the Yongsan break. The investigation is a smokescreen. I want the Association to announce Yeom's arrest as a corruption case—publicly, with financial misconduct as the charge—and I want the E-rank provisional observer in my custody released from Association detention. House arrest under my supervision.”

“The observer. Kang Jisoo.”

“Yes.”

The prosecutor's jaw tightened. “You're asking me to trade a high-level corruption arrest for one detainee.”

“I'm asking you to win.” Min-jun stood. “The arrest happens tomorrow morning or the evidence goes to the press. Your choice.”

The prosecutor left without another word. The suppression field died. Min-jun stood alone in the silence for a full minute, then walked back upstairs.

Hana's hands were shaking again when she returned to the office, but her voice came steady. “Three shell clinics. Same vendor registration number across all of them.

The payments go back fourteen years. Total routed is just over eight hundred million won in unaccounted disbursements. I cross-referenced with Yeom's approval codes. They match.“

She set a sheaf of printed records on the desk. The top page was a transfer ledger, columns of numbers bleeding into each other.

Min-jun scanned it. “Send the digital copies to the frequency I gave you. Then burn the physicals.”

Hana nodded. She didn't ask why.

The call came at two in the morning.

Min-jun was still in his office. Jisoo occupied the corner chair, arms folded, the Anchor Core's sealed case on the low table between them. He hadn't slept. The shadows under his eyes were deep enough to look bruised.

Min-jun's phone buzzed once. He answered without speaking.

A voice on the other end, clipped and official: “Director Yeom was taken into custody at twenty-three hundred hours. The Association will issue a public statement at zero-eight hundred. Your observer is being released to your custody as of now. A Guild transport detail is en route.”

The line went dead.

He laid the phone face-down on the desk. His gaze found Jisoo.

“You predicted this,” Min-jun said. “Three days ago, before Yongsan, you told me the Association would come after the guild for a gate break it couldn't explain. You said the financial angle would be the weak point. You named Yeom's division before you could possibly have seen the file.”

Jisoo didn't move. “I told you I read the patterns.”

“You told me you were an E-rank with an appraisal skill.” Min-jun's voice hadn't risen, but the temperature in the room dropped. “E-ranks don't read patterns across seventeen years of classified disbursements. They don't predict arrest windows.”

Silence.

Jisoo's hands stayed at his sides. He didn't look away.

“You saved Hana. You identified the Anchor Core. You found the sigil.” Min-jun listed each point like evidence tags on a crime scene. “And now a man I've been hunting for a decade sits in a cell because you told me where to look.”

“You want an explanation,” Jisoo said.

“I want to know if you're a weapon someone aimed at me.”

Another silence, longer. The lamp flickered.

Jisoo leaned forward, voice low and rougher than before. “I'm not your enemy. I can't explain why I know what I know—not yet.

But the people who killed your father are still operating. They have a weapon. The Anchor Core is part of it. And the cascade it's built for will make Yongsan look like a drill.“

Min-jun studied him. The scar across his eyebrow caught the lamplight, bisecting his expression into something unreadable.

Then he picked up the Anchor Core's case and removed the lid.

“Show me.”

The resonance scan took an hour. Hana calibrated the diagnostic array while Min-jun held the Core under the mana-lens. Jisoo stood at the display terminal, reading output faster than the machine could render it.

“There.” He tapped the screen. A waveform spiked at a frequency that matched no natural gate signature. “That's not a boss core. That's a relay. It's meant to receive a signal.”

“From what?” Hana leaned closer, exhaustion forgotten.

“A second device. Same design, different location.” Jisoo traced the frequency line backward. “The cascade isn't one gate breaking. It's multiple gates linked. This Core is the receiver. Activate it, and every gate within range goes critical at once.”

Min-jun's jaw tightened. “Range.”

“Hard to say without the transmitter's location. But based on the decay data from Gwangjin—” Jisoo paused, numbers assembling behind his eyes, fragments of a future that no longer existed translated into a guess he could justify. “Seoul metropolitan area. Minimum.”

Hana's face went pale.

Min-jun closed the Core's case. Precise, unhurried movements. When he spoke, his voice was completely level.

“So my father's death was a footnote in a budget report.”

The line hung in the air, dry and terrible. No one moved. No one responded. Min-jun continued without waiting.

“We locate the transmitter before they activate it. Hana, map every gate within fifty kilometers that's been cleared in the last five years. Cross-reference with Yeom's disbursement records. Jisoo, you're going to tell me how you know what this Core does and I'm going to stop asking until you're ready to answer.”

Jisoo opened his mouth.

Min-jun's phone buzzed.

The screen lit with a message from an unknown number. No sender ID, no routing data—just a block of encrypted text that decrypted itself the moment Min-jun picked it up.

You've killed one rat. The nest will now bury you.

He read it twice. Then he turned the screen toward Jisoo.

The guild's security alarms tripped.

Red lights pulsed along the hallway outside. The lock on the office door engaged with a heavy metallic thud. Hana flinched. The diagnostic array flatlined with a high, thin whine.

Min-jun placed the phone on the desk, face-up, the message still glowing.

“They're early,” Jisoo said.

From his inside pocket Min-jun pulled a keycard and tossed it to Hana. “Down the hall. The mana-lock room behind your office. Seal yourself in. Don't open it for anyone but me.”

Hana caught the card. Her knuckles were white. “Guild Leader-nim—”

“Now.”

She bolted. Footsteps hammered down the hallway just as the first impact hit the outer gate. The building shuddered.

Min-jun looked at Jisoo. The case file, the Anchor Core, the residue sample—all of it sat on the desk between them, evidence of a conspiracy seventeen years in the making.

“Your knowledge,” Min-jun said. “Is it enough to get us through the next hour?”

Jisoo met his eyes. The exhaustion in his face had given way to something harder, a clarity that had no business sitting behind the eyes of an E-rank observer.

“Yes.”

Min-jun held his gaze for one beat. Two. Whatever he found there, he didn't question it.

“Then we use it.”

The alarms screamed. The lights died. And in the dark, the counter-offensive began.
