Mine Alone: A Yandere's Devotion

The Hunter Association’s anomaly division operated out of the fourteenth floor of a glass tower in Yeouido that had been, until seventy-two hours ago, a mid-tier financial consulting firm.

The Association had acquired it on Tuesday afternoon — emergency requisition, standard new-world protocol, the consulting firm’s staff arriving Wednesday morning to find their keycards deactivated and a very apologetic letter of compensation waiting in their emails.

Speed over courtesy. That was the operating principle of the first week.

Floor fourteen was now three rows of analysts, six server towers running continuous panel data, and one woman who stood at the floor-to-ceiling window with her hands clasped behind her back and looked at Seoul like she was already responsible for it.

Her name was on the organizational chart as COMMANDER YUNA VALE — ANOMALY ASSESSMENT DIVISION, TIER 1.

She was thirty-one. She had the posture of someone who had decided very early that rooms arranged themselves around her rather than the other way around. Her Hunter rank was SS — one of eleven SS-ranks confirmed globally in the seventy-two hours since registration, a number so small that each one of them had already become a geopolitical variable.

She hadn’t entered a Gate yet.

She didn’t need to. What she was doing here was worth more than anything she’d accomplish clearing Gates.

”Pull it up again,” she said.

Behind her, an analyst complied without comment. The main display screen populated with a panel data readout — anomaly flagged, tier two review, name at the top.

DILLAN RUREN. AGE 22. RANK: F—. ABILITY: UNCLASSIFIED.

Below it, three Gate clear records in three days. D, C, B. Solo or near-solo. Time stamps. Essence absorption metrics that the system had recorded automatically and flagged because the numbers were wrong — not wrong like an error, wrong like a scale applied to something that didn’t fit the scale.

”Essence absorption rate,” she said.

”Thirty-one times the B-rank average for the third Gate,” the analyst said. ”And accelerating. Each Gate the rate increases proportionally to the previous — not linearly, exponentially.”

”So by the time he hits an A-class Gate—”

”The projection models break down. The curve goes vertical.”

She was quiet for a moment.

”Unclassified ability,” she said. ”The system can’t assess him.”

”Correct. Every scan returns an error. We’ve tried manual reclassification three times. It won’t hold — the system rejects the override and returns to error state within minutes.”

”Because the ability is growing faster than the classification can update.”

”That’s our working theory.”

Vale looked at the name on the screen.

Dillan Ruren. Former guild admin. No combat training on file. No prior Hunter registration. An F-minus rank that the system had apparently invented specifically for him, which she found — not funny exactly, but something adjacent to it. The algorithm encountering something it couldn’t process and deciding the correct response was a new punctuation mark.

”Current status?” she said.

”Unaffiliated. Had contact with a B-rank Hunter from Sentinel Guild this morning — they exchanged credentials. No affiliation confirmed.” A pause. ”He does have a consistent partner showing up in Gate entry logs. A-rank healer, name Sera Voss. No prior relationship on record — first contact appears to be day two.”

”Voss.” Vale filed the name. ”Assessment?”

”Clean record. No red flags. Standard A-rank healer profile.” Another pause. ”She’s fast though. Very fast, in terms of establishing proximity to the subject.”

Vale said nothing.

”Ma’am, the division chief wants a recommendation by end of week. Whether to approach the subject for—”

”I’ll handle the approach,” she said.

Silence behind her.

”Personally,” she added, in a tone that closed the topic.

She looked at Dillan Ruren’s panel data on the screen.

The curve went vertical.

Interesting, she thought.

Mira Chen had been streaming for six hours straight when she found the clip.

Not unusual. She streamed Gates, she streamed prep, she streamed the spaces between — the road to the checkpoint, the queue, the post-clear cooldown where she sat on whatever surface was available and talked to her chat with the easy fluency of someone who had grown up speaking to cameras. Ten million followers didn’t maintain themselves. They needed feeding, and Mira was good at feeding things.

She was good at most things, which she knew without arrogance — arrogance implied insecurity underneath and she didn’t have that either. She was simply accurate about her own capabilities in the same way she was accurate about everything else. S-rank combat Hunter, age twenty-four, top-fifty globally on the new ranking boards, guild-affiliated but functionally independent because Stormfront Guild had learned within the first year that attempting to manage Mira Chen was like attempting to manage weather.

Her stream setup was a converted bedroom in her apartment — three cameras, professional lighting, a secondary monitor for chat, a primary monitor for her panel and Gate data. Clean, minimal, ruthlessly functional.

She’d been reviewing B-class Gate footage from this morning for a future video breakdown when the clip appeared in her recommended feed.

A short one. Forty seconds. Posted by a forum account called @GateFreaks_KR with the title: F-MINUS SOLO CLEARS B-CLASS?? WATCH THE ABSORPTION (INSANE)

She clicked it without particular expectation.

Forty seconds later she rewound it and watched it again.

Then again.

The footage was checkpoint camera — low angle, slightly grainy, the kind of automatic recording that Gate sites used for liability purposes and that inevitably leaked to forums within hours. It showed the Gate interior’s outer zone. It showed a figure — male, average height, no gear worth mentioning — moving through a cluster of B-class monsters with the fluid non-technique of someone operating entirely on instinct and something else.

The something else was the part she watched four times.

Contact. Dissolution. The monsters didn’t die — they unmade. Like watching a sandcastle hit by a wave, except the wave was invisible and coming from his hands and he was doing it to things that had killed fully-equipped C-rank teams that morning three districts over.

”Chat,” she said, out loud, to her stream.

Her chat was currently four thousand people discussing her earlier Gate run.

”Chat, I need you to find everything about this person.” She screenshot the forum post. Held it up to the camera. ”F-minus rank. Solo-cleared D, C, and B in three days. This morning’s B footage just leaked. His name is apparently Dillan Ruren. I want — no, chat, I don’t want your speculation, I want information. Forum threads, Association data, anything. Go.”

Chat went.

She watched the clip a fifth time while they worked.

The way he moved — not skilled, not trained, but oriented. Like a compass. Like something that always knew where north was and moved toward it without consultation.

She’d been an S-rank for eight months. She’d cleared Gates that had hospitalized entire A-rank teams. She knew what capability looked like from the inside, the texture of it, the specific gravity of someone who carried more than their rank suggested.

This was different.

This wasn’t hidden capability. This was something that didn’t have a category yet.

Her chat exploded.

@StreamKing_99: FOUND HIM — forums have his full profile@HunterWatcher: He’s unaffiliated!! No guild!!@MiraSimp4Ever: MIRA GO GET HIM@GateAnalyst_KR: The absorption rate in this clip doesn’t match ANY known ability class@StreamKing_99: he has a partner tho — A-rank healer, been with him since day 2

She read the last message twice.

Partner.

She looked at the clip again. At him. At the way he moved through the Gate with that compass-needle focus, consuming everything the B-class interior threw at him, entirely unbothered by the scale of what he was walking into.

”Interesting,” she said, to no one in particular.

Her chat took that as significant — it was, in the Mira Chen streaming vocabulary, approximately the strongest positive assessment she made on stream — and erupted accordingly.

She closed the clip. Opened her Gate schedule for tomorrow.

There was a B-class projected in Mapo district. A second one in Yongsan.

She pulled up the Hunter Association’s public entry logs.

Cross-referenced Dillan Ruren’s last three Gate entries with district and time patterns.

Smiled.

”Chat,” she said. ”I think I know where I’m going tomorrow.”

Her chat lost its mind.

She turned the monitor off and sat in the quiet of her apartment for a moment, one leg folded under her, looking at the dark screen where the clip had been.

F-minus, she thought.

Sure.

Dillan didn’t know about the stream.

He was sitting at his kitchen table at 9 PM with his panel open and a list he’d been building for the past hour — every stat transfer, every essence absorption, every anomaly flag from the past three days — trying to construct a picture of what was happening to him from the data points available.

The picture was not entirely reassuring.

[CURRENT STAT OVERVIEW — UNOFFICIAL ESTIMATE]

Speed: Significant increase. Baseline human + D-class x1 + C-class x3 + B-class x12.

Strength: Moderate increase.

Reflex: Significant increase.

Endurance: Unknown — no clear transfer yet.

Ability: [DEVOUR] — passive, unclassified, no ceiling confirmed.

The numbers were getting harder to ignore. Three days ago he couldn’t run a mile without his knees complaining. This morning he’d moved through a B-class Gate engagement that should have killed him and the only physical evidence was a shoulder that had stopped hurting somewhere around the third absorption.

It’s healing me too, he thought. The essence. It’s not just building stats. It’s fixing things.

He added that to the list.

His phone buzzed.

Unknown number. He almost ignored it. Looked at it anyway.

A text, no name attached, just a number he didn’t recognize:

Saw your B-class footage. Clean work for someone with no technique. — M

He stared at it.

Typed back: Who is this.

The reply was immediate:

Someone who’s going to find out anyway. Thought I’d give you the courtesy of a heads up. See you tomorrow, Dillan.

He looked at the message for a long time.

Set the phone down.

Looked at his panel.

Looked at the Sentinel Guild card from Jung Hana, sitting on the table.

Looked at the Association anomaly flag still blinking in the corner of his display.

The checkpoint officer said someone in data division flagged my file, he thought. The Association is watching. A B-rank Hunter gave me her card this morning. A stranger just texted me like they already know my schedule.

He thought about Sera. You have me. That’s sufficient.

He thought about the Gate tomorrow.

Three days, he thought. It’s been three days.

He went to bed.

He did not sleep particularly well.

Across the city, in an apartment she’d chosen specifically for its sightline to the Mapo district Gate site, Sera Voss sat at her desk at 11 PM.

Open on her primary monitor: Dillan’s public Hunter profile. She’d been reading it for an hour — not because it contained new information, she had all the information, but because looking at it felt like proximity. Like a form of presence.

Open on her secondary monitor: the contact list she’d pulled from a guild admin database she shouldn’t have had access to.

She did have access. She’d acquired it six months ago for reasons unrelated to this, filed the credentials away under future use, and forgotten about them until tonight.

Dillan’s old contacts at Ironspire Guild — former coworkers, the kind of low-level social infrastructure that people maintained without thinking about, that provided the texture of ordinary life. Three of them had tried to reach him in the past two days. Checking in. The way people did.

She read their messages — she shouldn’t have been able to, she could, she had — and assessed them with the quiet precision she brought to everything.

One was harmless. Pure check-in, no real investment.

One was a former female coworker. Warm tone. More than check-in. A history in the subtext.

She opened the guild admin system.

Found the notification settings for guild-adjacent messaging.

Made a small adjustment. Quiet. Invisible. The kind of thing that looked like a system glitch if anyone ever noticed — a routing error that would bounce Dillan’s incoming messages from that specific contact to an unmonitored folder.

Not deleted. Just — redirected. She wasn’t cruel.

She closed the system.

Opened the lock screen photo.

”You don’t need distractions,” she told it softly. ”Not right now. You need to focus. I’ll help you focus.”

She set the phone face-down on the desk.

Opened tomorrow’s Gate schedule.

Smiled.
