Death, Dragons and Dimensional Displacement

Summary:

Harry Potter — immortal Master of Death after fifty years alone in a nuclear wasteland — approaches the Veil and demands Death let him stop existing. Instead, Death dissolves the three Hallows into him and flings him through dimensions. He lands in Kuoh City, Japan, with a sentient black gauntlet housing Vritra, an ancient Dragon King.

DISCLAIMER
I don't own Harry Potter. That's J.K. Rowling's thing. I don't own High School DxD either. Ichiei Ishibumi gets credit for that beautiful, chaotic, suspiciously-perverted mess.
What I do own is this story, Harry's new cosmic situation, and Vritra's deeply unimpressed attitude toward everything.
No profit. No copyright infringement intended. Just a broke writer having an absolutely unhinged amount of fun.

Chapter 1: Prologue

Chapter Text

Look, I know what you're thinking.

*"Harry Potter, aren't you supposed to be the Chosen One? The Boy Who Lived? The guy who saved the Wizarding World?"*

Yeah, well, about that.

Turns out "saving the world" has an expiration date. And that date was approximately forty-seven years, three months, and sixteen days ago when some absolute *genius* decided nuclear warfare was a proportionate response to... honestly, I stopped keeping track of what people were fighting about.

The point is: everyone died.

Everyone except me.

Because apparently when you collect all three Deathly Hallows like they're Pokémon cards, Death himself goes, "You know what? This guy? He doesn't get to log off."

Thanks, Death. Really. You're a pal.

---

So there I was, standing in the ruins of the Department of Mysteries—which, let's be honest, was mysterious even *before* it became a radioactive wasteland—staring at the Veil of Death.

You remember the Veil, right? That creepy archway that ate my godfather? Yeah. That one.

It was still standing.

Everything else had crumbled. The Time Room? Sand and broken glass. The Brain Room? Don't ask. The Love Room—

Actually, I'd rather not talk about the Love Room.

But the Veil? Pristine. Not a scratch on it. Just hanging out, whispering its creepy little whispers like it was auditioning for a horror podcast.

*"Come home, Harry..."*

*"End it, Harry..."*

*"Stop talking to yourself, Harry, people are starting to worry—"*

Wait, that last one was my inner monologue.

Hard to tell the difference anymore when you've been alone for five decades.

"Right," I said, rolling my shoulders. My left arm was still healing from this morning's radiation burn. The flesh rippled and knit itself back together with the sound of wet paper tearing. Lovely. "Let's do this."

I pulled out the Elder Wand.

**[AUTHOR'S NOTE: In case you're wondering, yes, Harry Potter just pulled out the most powerful wand in existence like it was a Swiss Army knife. Keep up.]**

The thing hummed in my hand. It had been doing that more lately. Less "obedient magical tool" and more "ancient artifact that's getting ideas."

I didn't like it when magical objects got ideas.

That's how you end up with horcruxes.

Or me.

"Death?" I called into the Veil, my voice echoing in the empty chamber. "You there, buddy? Pal? Potentially-fictional-anthropomorphic-personification-of-mortality?"

Silence.

Then—

Laughter.

Not the fun kind. The "oh-no-the-villain-has-arrived" kind.

I spun around, wand up, and came face-to-face with Death.

Actual, literal Death.

Tall. Skeletal. Wearing robes that looked like they were cut from the fabric of "nope" itself. His face was a skull, because of course it was, and his eye sockets glowed with pale light that made my skin crawl.

Or they would have, if my skin wasn't currently regenerating from mild radiation poisoning.

"You know," I said, because apparently my trauma response is sarcasm, "I pictured you differently. More... Ryan Gosling, less Halloween decoration."

Death tilted his skull. **YOU CALLED ME FRIEND.**

His voice wasn't a voice. It was the sound of every last breath ever taken, compressed into words.

I lowered my wand. Slightly.

"Yeah, well. You've been more consistent than most of my relationships. And that's including the Weasleys' Christmas dinners."

**YOU WISH TO DIE.**

"I wish to *stop,*" I corrected. "Dying implies I can. Stopping implies I get a choice." I gestured at the ruins around us. "This? This isn't living. This is just... continuing."

Death considered this.

**THE HALLOWS MADE YOU MASTER OF DEATH.**

"Yes, and I'd like to speak to the manager about that."

**I AM THE MANAGER.**

"Then I'd like a refund."

**NO.**

"Come on—"

Death reached out with one impossible hand—seriously, the fingers were too long, way too long—and *touched* my chest.

Right where the Resurrection Stone hung on its chain.

"Wait—" I started.

Too late.

---

Pain isn't the right word.

Pain is when you stub your toe. Pain is when Hermione hits you with a Stinging Hex for being an idiot.

This was *worse*.

The Elder Wand in my hand didn't break—it *dissolved.* Like it was made of sugar in water, except the water was my nervous system and the sugar was *pure concentrated agony.*

I felt it thread through me. Into my bones. Through my bones. *Becoming* my bones.

The Resurrection Stone *shattered* against my chest. I heard it break—that crystalline crack—and then I felt each piece burrow into my heart like shrapnel made of memory.

The Cloak of Invisibility—my father's Cloak, the one inheritance I had left—*unraveled.*

Not into thread.

Into shadow.

Into the space between seconds.

Into *me.*

I tried to scream but my mouth wasn't where it should be.

I tried to run but I didn't have legs anymore.

I tried to *die* but—

**YOU CANNOT.**

Death's voice was everywhere. Inside my skull. Inside my chest. Inside the space where I used to be Harry James Potter and was now rapidly becoming something with significantly fewer OSHA safety certifications.

**THE HALLOWS WERE LIMITS, HARRY POTTER. BOUNDARIES. RULES.**

**YOU BROKE THE RULES.**

**SO REALITY BREAKS YOU.**

"THIS IS—" I managed to choke out, "—THE WORST—CUSTOMER SERVICE—"

The Veil *tore open*.

Not like a door.

Like reality had just received a strongly-worded letter of complaint and decided to quit on the spot.

And I *fell*.

---

There's no good way to describe falling through the space between worlds.

Imagine every bad trip you've never taken, combined with that dream where you're falling and you wake up just before you hit the ground.

Now imagine you *don't* wake up.

You just keep falling.

For what might be seconds or centuries—time means nothing when you're experiencing ALL of it simultaneously—I was AWARE.

Aware that my bones were the Elder Wand now. Every skeletal inch humming with the ability to command magic itself.

Aware that my heart was the Resurrection Stone. Still beating. Each beat a memory of everyone I'd ever lost. Mum. Dad. Sirius. Remus. Fred. *Everyone.*

Aware that my skin was the Cloak. Here and not-here. Visible only when I wanted to be.

**THIS IS YOUR PUNISHMENT,** Death said, his voice the only stable thing in the chaos. **AND YOUR GIFT.**

"I don't—want—"

**ANOTHER WORLD NEEDS A MASTER OF DEATH.**

"FUCK YOUR—"

The void *clenched.*

Like a fist.

And spat me out.

---

I hit the ground like a meteorite having a really bad day.

For a moment, I just lay there, face-down on concrete that was definitely *not* London concrete (yes, concrete has regional variations, shut up), trying to remember how to breathe.

My body was *mine* again.

Mostly.

Twenty years old, maybe? The age I'd been when everything went to hell in a handbasket made of nuclear fire.

The scars were gone.

But I could *feel* them. Written in the code of whatever I was now.

I pushed myself up—

And saw my left hand.

"Oh, *bollocks*."

A gauntlet covered my hand and forearm. Black as the Veil, with silver edges that caught the light of a moon that was *definitely* not Earth's moon (wrong size, wrong color, possibly sentient—hard to say).

Runes crawled across the surface like beetles made of light.

The gauntlet *pulsed*.

Once.

Twice.

Like a heartbeat.

And then a voice—gravelly, ancient, and deeply unimpressed with *everything*—echoed in my skull.

**[Kid,]** the voice said, like Clint Eastwood had been asked to narrate a cosmic horror story, **[you look like hell.]**

I sat up. Slowly.

"I'm sorry," I said. "Did my hand just *talk* to me?"

**[Your hand? Boy, I'm a five-thousand-year-old Dragon King sealed in a Sacred Gear that your weird death-god situation just created. Show some damn respect.]**

I stared at the gauntlet.

The gauntlet stared back.

(Could gauntlets stare? This one was managing it.)

"I've had a *really* long fifty years," I said carefully. "So I'm going to need you to back up and explain—slowly—what the *hell* is happening."

**[You died,]** the voice said flatly. **[Became Death. Got shoved into a new universe. The system took one look at you and went 'we don't have a classification for this clusterfuck' and turned you into a Sacred Gear.]**

"A what now?"

**[And I'm Vritra. The Prison Dragon. The Black One. The Dragon King who makes the other Dragon Kings nervous at parties.]**

"There are *parties*?"

**[Not anymore. I ruined them.]**

A pause.

**[Also, you've got about ten seconds before the local supernatural community realizes a Longinus-class Sacred Gear just spawned in their territory, so you might want to—]**

Black wings *erupted* from my back.

Not feathered.

Not scaled.

Made of *nothing.* Of the spaces between things. Of the Veil itself.

I looked at them.

Looked at the gauntlet.

Looked at the sky, which was starting to fill with *things*—glowing figures, winged shapes, entities that made my Hallows-enhanced senses scream warnings.

"Vritra," I said calmly.

**[Yeah?]**

"I'm going to need therapy."

**[Kid, we ALL need therapy. Now get moving before the Angels show up.]**

"Angels are *real*?"

**[So are Devils. And Dragons. And Gods. Welcome to the deep end of the pool.]**

"I can't swim."

**[Then you better learn quick.]**

Somewhere in the distance, a school bell rang.

I looked down at myself. Gauntlet. Wings. Probably glowing with eldritch power or whatever.

"This is fine," I muttered. "This is *totally* fine."

**[Kid,]** Vritra drawled, **[you're full of shit.]**

"I know."

And then I ran.

Because apparently, that's what Harry Potter does.

Even in new dimensions.

Even with a cowboy-dragon in his hand.

*Even when he's completely, utterly, magnificently screwed.*

# THE SHOCKWAVE (OR: HOW TO BECOME SUPERNATURALLY FAMOUS IN UNDER FIVE MINUTES)

**Chapter Two: In Which Everyone Has Opinions About The New Guy**

---

## GRIGORI HEADQUARTERS - FALLEN ANGEL TERRITORY

Azazel was having what could generously be called a "decent" day.

Not *good.* Let's not get crazy.

But decent.

He'd managed to finish his morning coffee without anyone declaring war, inventing a catastrophe, or asking him deeply uncomfortable questions about his life choices. As Governor-General of the Grigori—the Fallen Angel organization—this counted as a *win.*

He was elbow-deep in Sacred Gear components, tweaking a new Twice Critical prototype, humming something that might have been music if you were very generous with the definition—

When every Sacred Gear in his workshop *screamed.*

Not literally.

Worse.

The sound bypassed his ears entirely and went straight for his *soul.*

"Oh, *come on*—"

Golden light erupted from every crystal, every half-assembled Balance Breaker component, every carefully calibrated magical circuit he'd spent *weeks* building. His twelve black wings snapped open reflexively as the workshop became less "laboratory" and more "natural disaster in progress."

Tools clattered. Blueprints combusted. His favorite coffee mug—the one that said "World's Okayest Fallen Angel" in Comic Sans—*exploded.*

"NOT THE MUG!"

But the mug's sacrifice was meaningless compared to what Azazel was *feeling.*

Power.

Not normal power.

Not "oh hey, another Sacred Gear awakened" power.

This was *"someone just downloaded an expansion pack into reality itself"* power.

And underneath it—woven through it like DNA through a cell—was something that made his ancient, jaded, seen-it-all Fallen Angel instincts sit up and pay *attention.*

Dragon.

Old dragon.

*Sealed* dragon.

"No," Azazel whispered. "Nonononono—"

The door burst open.

Shemhazai—his second-in-command and the living embodiment of "I'm surrounded by idiots"—stood there with a tablet and an expression that suggested he was reconsidering every life choice that had led him to this moment.

"Azazel-sama," he said, because even in crisis mode, Shemhazai was *formal.* "We're detecting—"

"A new Longinus-class Sacred Gear, yeah, I'm *aware.*" Azazel was already moving, grabbing his coat, his phone, his emergency flask of "dealing with cosmic bullshit" whiskey. "Where?"

"Japan. Kuoh City."

Azazel stopped. Turned. Stared.

"You're *kidding.*"

"I am not."

"Of *course* it's Kuoh. Why is it *always* Kuoh?" Azazel threw his hands up. "What does that town have? Is there a sign? 'Welcome to Kuoh City, Home of Supernatural Clusterfucks Since—'"

"Azazel-sama."

"Right. Focus." He pulled out his phone, already dialing. "Get me a full workup. Ley line activity, magical signatures, any witnesses—*everything.*"

The phone rang once.

**"Michael-sama speaking."**

"Yo, Mike, we've got a situation."

**"Azazel-san."** The leader of Heaven's Seraphs sounded tired. Which, fair. Running Heaven after God died was basically a full-time job with no vacation days. **"How many times must I ask you not to—"**

"New Longinus. Manifested five minutes ago. Kuoh City."

Silence.

The kind of silence that meant someone very powerful was thinking very hard about whether to panic.

**"...I see. I'll contact Sirzechs-sama immediately."**

"Already sent him a message. Conference call in ten." Azazel paused. "Michael-sama? This one's different."

**"Different how?"**

"It made every Sacred Gear I own scream like someone was torturing them. And I *felt* it. Like reality opened a door that had a big sign saying 'DO NOT OPEN' in every language including the dead ones."

Another pause.

**"I'll mobilize the Seraph-class Angels."**

"Good call. Because Mike? I think we just got a new player in the Great War. And I don't think they know the rules."

**"That's what concerns me."**

The line went dead.

Azazel looked at Shemhazai. "Get me everything on Kuoh. Student registries, supernatural residents, ley line convergence points, recent magical anomalies—even that weird report about the perverted trio."

"Azazel-sama, if I may—what kind of Sacred Gear could cause this reaction?"

Azazel remembered the sensation. Death and Dragon wound so tight together they might as well be the same entity. Power that didn't just *exist* but *imposed itself* on reality.

"The kind that could end the war," he said quietly. "Or start a new one that makes the last one look like a schoolyard fight."

"Is that... good?"

"Shemhazai, I've been alive for thousands of years. You know what I've learned?"

"What?"

"Anything powerful enough to end a war is usually powerful enough to end everything else too. Including us."

---

## HEAVEN - THE SEVENTH LAYER

Michael-sama—leader of Heaven's Seraphs and the guy stuck with the *fun* job of running things after God died—stood in the throne room and tried not to have a complete breakdown.

This was harder than it sounded.

Because the System—the massive divine infrastructure that kept Heaven running, blessed the faithful, and generally prevented reality from collapsing like a badly-made soufflé—was *freaking out.*

Golden light pulsed erratically through the crystalline architecture. Angels fled their posts as holy energy surged uncontrollably through the ley lines. And the *prayers*—

Oh, the prayers.

Every Saint. Every martyr. Every holy soul who'd received even a *fragment* of God's power—

They were all screaming.

Not in pain.

In *recognition.*

"This is fine," Michael muttered, even though it definitely wasn't. "This is *totally* fine."

"ONII-SAMA!"

Gabriel-chan burst into the throne room, her twelve golden wings disheveled in a way that would have been adorable if the situation wasn't *terrifying.* As Heaven's most beautiful Angel and chief messenger, Gabriel-chan usually looked *perfect.*

Right now she looked like she'd been electrocuted.

"I know," Michael said, hands moving in complex patterns as he tried to stabilize the chamber. Holy light poured from his wings. "What are the diagnostics showing?"

"The System is trying to classify something. A Sacred Gear manifestation. But it *can't*, onii-sama." Gabriel-chan's violet eyes were wide. "It keeps running the same analysis over and over. It's like... it's like it found something it doesn't have words for."

Michael felt something cold settle in his stomach.

The System was *God's* creation.

It had words for *everything.*

Angels. Devils. Fallen. Dragons. Gods. Eldritch abominations. That one weird thing in the Pacific that everyone pretended didn't exist.

If the System didn't have words for something...

"Show me."

Gabriel-chan waved her hand. A holographic display materialized—all crystalline complexity and divine mathematics that made mortal brains bleed.

At the center was a single entity.

The readout made Michael's blood run cold.

**[CLASSIFICATION: ERROR - UNKNOWN ENTITY TYPE]**

**[SACRED GEAR DESIGNATION: LONGINUS-CLASS (UNCONFIRMED)]**

**[THREAT ASSESSMENT: MAXIMUM]**

**[CONCEPTUAL AUTHORITY DETECTED: DEATH, VOID, SEVERANCE, ENDING]**

**[DRAGON PRESENCE CONFIRMED: VRITRA (PRISON DRAGON KING)]**

**[WARNING: ENTITY DOES NOT REGISTER AS HUMAN/DEVIL/ANGEL/FALLEN/DRAGON/YOUKAI]**

**[WARNING: ENTITY POSSESSES INDEPENDENT AUTHORITY OVER DEATH CONCEPT]**

**[WARNING: SYSTEM CANNOT ADJUDICATE - AUTHORITY CONFLICT WITH DIVINE MANDATE]**

**[RECOMMENDATION: EVACUATE REALITY]**

Michael read it once.

Twice.

Three times.

"This is impossible," he said finally.

"The System doesn't lie, onii-sama."

"Independent authority over Death?" Michael's voice was sharper than he intended. "Kami-sama was the only one with that dominion. When He fell in the Great War, Death became an autonomous concept—something that existed but couldn't be *wielded*."

"And yet." Gabriel-chan gestured at the display. "Here we are."

Michael looked at his sister. Gabriel-chan, the messenger who'd announced God's will to prophets, who'd comforted dying saints, who could face down Satan-class Devils without flinching—

She looked *scared.*

"Location?"

"Kuoh City, Japan. The same territory where—"

"Where Sirzechs-sama's imouto operates her peerage. Where Azazel-san conducts his Sacred Gear research." Michael's mind raced. "The ley lines there are already destabilized from the recent—"

The throne room *shuddered.*

Every Angel in Heaven felt it.

A presence that *should not exist* pressing against the fabric of reality like a hand against wet paper.

Michael made his decision.

"Send an observer team. Seraph-class, experienced, *non-aggressive.* I want intelligence, not a fight."

"And if they're hostile?"

Michael thought about the System's recommendation.

*Evacuate reality.*

"Then we pray," he said quietly, "that Kami-sama left us enough power to survive."

## THE UNDERWORLD - LUCIFER'S PALACE

Sirzechs Lucifer was not easily surprised.

When you're one of the Yondai-Maou—the Four Great Satans who ran Devil society—you saw a *lot.* Political intrigue. Rating Game drama. His imouto Rias's increasingly creative attempts at cooking (which somehow violated thermodynamics *and* Geneva Conventions).

But this?

This was *sugoi* in the worst possible way.

He stood in his study, crimson hair falling around his face, as the Hakai no Chikara—the Power of Destruction, his unique Devil ability—*resonated* with something in the human world.

Not harmoniously.

*Antagonistically.*

His power wanted to destroy things. Unmake them. Reduce matter and energy to nothing.

Whatever had just manifested *was* nothing.

Or commanded it.

Or—

"Sirzechs-sama."

Grayfia Lucifuge, his Queen and wife, appeared in the doorway. Her silver hair was perfect as always, but her normally composed expression had cracks in it.

Not good.

Grayfia-san could face down Elder-class Devils without blinking. If *she* was shaken...

"You felt it too," Sirzechs said. Not a question.

"Every Devil in the Makai felt it, Sirzechs-sama. The Yondai-Maou have convened an emergency council."

"Let me guess. Ajuka-kun wants to study it, Serafall-chan wants to befriend it, and Falbium-kun wants to go back to sleep?"

"Accurate assessment." Grayfia's lips twitched. Almost a smile. "Ajuka-sama's exact words were 'fascinating and potentially apocalyptic in equal measure.'"

"Sounds like him." Sirzechs moved to the window. The Makai sprawled below—impossible architecture, demonic beauty, the accumulated power of Devil-kind. "What do we know?"

"The manifestation occurred in Kuoh City. Rias-sama's territory."

Sirzechs went very, *very* still.

His imouto.

His precious little sister.

*His territory.*

"Rias-chan."

"She's reported no hostile activity yet. However, the Sacred Gear that manifested is—" Grayfia consulted a report that looked like it had been written by someone having a panic attack. "—unprecedented. Our analysts believe it's either a fusion of multiple Longinus-class Gear, or something that *transcends* the Longinus classification entirely."

"That's impossible. Sacred Gears are bound by God's System. Even Longinus-class Gear can't exceed those parameters."

"Nevertheless, Sirzechs-sama."

He turned. "What about the wielder?"

"Unknown. No birth records. No magical signature in any database. No registration with any faction." Grayfia's expression was carefully neutral. "It's as if they simply... *appeared.*"

"Devils don't just appear."

"No, Sirzechs-sama. They don't."

Sirzechs felt the Hakai no Chikara coil in his chest. Eager. *Interested.*

His power had never been *curious* before.

It destroyed things. That was its entire purpose.

But now? Now it was responding to this unknown entity like a predator recognizing another predator.

"Contact Rias-chan. Tell her observe only, no engagement. And send backup—experienced members. If this Sacred Gear user is as strong as the readings suggest—"

"Reinforcements may be... problematic, Sirzechs-sama."

"Explain."

"According to Ajuka-sama's analysis, this entity doesn't register on our detection systems. It exists *outside* the normal supernatural hierarchy."

Understanding hit like a truck.

"They're not bound by the treaty."

"Correct."

The treaty between the Three Factions—Angels, Fallen, and Devils—had ended the Great War. It established rules. Boundaries. Systems of accountability.

But those rules only applied to *recognized members.*

If this entity wasn't recognized...

"They could attack Angels without Heaven declaring war on the Makai," Sirzechs said slowly. "Or Devils without triggering the treaty's retaliation clauses."

"Hai, Sirzechs-sama."

"Which means every faction will want to either recruit them or eliminate them before their rivals can."

"Also correct."

Sirzechs sighed. "I miss the old days. When our biggest crisis was scheduling conflicts in the Rating Games."

"Shall I contact Rias-sama?"

"Yes. And Grayfia-san?" He looked at his wife. "Tell her to be *careful.* If this entity truly has authority over Death itself..."

He didn't finish.

He didn't need to.

## KUOH ACADEMY - OCCULT RESEARCH CLUB (ORC)

Rias Gremory was doing paperwork when reality decided to have a seizure.

One moment, she was reviewing territory reports, sipping tea, living her best Devil heiress life.

The next, her Hakai no Chikara *surged.*

Papers disintegrated. The teacup exploded. Akeno Himejima—her Queen, best friend, and resident sadist—yelped as Raijin no Chikara (Lightning God's Power) crackled across her skin involuntarily.

"Ara ara!" Akeno gasped. "What was—"

"Did you feel that?" Rias was on her feet, crimson hair blazing with demonic power. Her blue-green eyes glowed.

"Hai, Buchou." Akeno's expression was caught between arousal and terror. "That was... *sugoi.*"

Sugoi was an understatement.

Rias was a High-Class Devil. Heiress to the Gremory Clan. Trained since childhood to recognize power signatures, classify threats, navigate Devil politics.

This?

This was *wrong.*

Her Hakai no Chikara had *responded* to whatever manifested.

Not like "oh, there's something powerful nearby."

Like it had recognized a *rival.*

An *equal.*

"Akeno-san, contact everyone. Full alert status. I want Koneko-chan, Yuuto-kun, and Gasper-kun here *immediately.*"

"Do you think it's an attack, Buchou?"

"I think—"

The ORC door slammed open.

Sona Sitri stood there, glasses askew, her normally perfect Student Council President composure *shattered.*

Behind her, Tsubaki Shinra—her Queen—looked equally shaken.

"Rias-san." Sona's voice was tight. "Tell me you felt that."

"I did."

"And?"

Rias met her fellow Devil heiress's eyes. Sona was one of the smartest tacticians she knew. Calm. Analytical. Unflappable.

Right now she looked like someone had just told her thermodynamics was optional.

"Sacred Gear," Rias said. "Has to be. Nothing else generates that kind of power spike."

"Longinus-class?"

"At minimum." Rias moved to the window. Kuoh Academy sprawled below—peaceful, normal, completely unaware of the supernatural forces controlling it. "Sona-san, whatever just manifested... it's *here.* In Kuoh."

"Impossible. We monitor all Sacred Gear users in our territory. We would have detected an awakening—"

"Unless they're new."

"An awakening? Here? *Now?*" Sona adjusted her glasses with shaking hands. "With the peace talks scheduled, the ley line instability, and Issei-san's recent power boost—"

"The timing is terrible."

"The timing is *always* terrible."

Fair point.

"Mobilize your peerage," Rias decided. "I'll mobilize mine. We sweep the city systematically, find this Sacred Gear user before—"

Her phone rang.

The ringtone was *specific.* "Crimson Air" by Garnidelia—assigned to exactly one person.

Rias answered. "Onii-sama."

**"Rias-chan."** Sirzechs Lucifer's voice was calm. The kind of calm that meant someone very powerful was working *very hard* not to panic. **"I assume you felt the manifestation."**

"Hai."

**"Good. Listen carefully, imouto. A new Longinus-class Sacred Gear has appeared in your territory. The wielder is unknown. Potentially extremely dangerous. I'm sending reinforcements, but until they arrive—"**

"Observe but don't engage. I know the protocol, onii-sama."

**"This isn't protocol, Rias-chan. This is *survival.*"**

The seriousness in his voice made her blood run cold.

**"The entity that manifested has independent authority over Death. Not death as killing. Not death as a concept. *Death* as a fundamental force that can end anything. Including Devils. Including immortals. Including *concepts themselves.*"**

The room went silent.

Even Akeno looked pale.

"Onii-sama—"

**"If you encounter them, do NOT attack. Do not threaten. Do not even *irritate* them, understood?"**

"Understood."

**"I'm serious, Rias-chan. This isn't a Rating Game. This isn't training. If this entity decides you're a threat—"** He paused. **"—there's a non-zero chance they could erase you so completely that your Evil Pieces wouldn't trigger. Your reincarnation wouldn't activate. You would simply... *stop.*"**

Rias felt something cold settle in her chest.

"I'll be careful."

**"And Rias-chan? Your Pawn—Hyoudou Issei-kun, the Sekiryuutei (Red Dragon Emperor)—keep him away from this. Far away."**

"Why?"

**"Because this new Sacred Gear contains Vritra. The Prison Dragon King."**

Oh.

*Oh no.*

"Ddraig-san and Vritra-san... they're rivals."

**"Hai. Which means if Issei-kun and this wielder meet, one of two things happens. Either they become best friends and team up to cause apocalyptic levels of property damage..."**

"Or they fight to the death trying to prove whose Dragon is stronger."

**"Exactly. So keep them separated until we know more."**

The call ended.

Rias looked at Sona. "You heard?"

"Every word." Sona adjusted her glasses, her analytical mind already working. "This is... *yabai.* (This is bad.)"

"That's one way to put it."

"What do we do, Buchou?" Akeno asked.

Rias moved back to the window. Somewhere out there, in *her* territory, was an entity powerful enough to make the Yondai-Maou nervous.

An entity with power over Death itself.

An entity that was probably confused, possibly hostile, and *definitely* dangerous.

"We find them," Rias said. "Before anyone else does."

"And then?"

"And then we hope they're reasonable."

"And if they're not?"

Rias's smile had no humor in it.

"Then we *improvise.*"

## KYOTO - YOUKAI TERRITORY

Yasaka-sama, leader of the Kyoto Youkai faction and nine-tailed Kitsune of considerable power (and, let's be honest, *assets*), was meditating when the ley lines *sang.*

She'd been deep in elemental communion, feeling the pulse of spiritual energy through Japan's ancient network—the natural power grid that connected shrines, sacred sites, and supernatural territories—

When something *crashed* into the system.

Not entered gracefully.

*Crashed.*

Like a meteor made of concentrated "oh shit."

The sensation hit her *directly.*

Youkai—especially Kitsune—were naturally connected to the ley lines. It was how they sensed disturbances, drew power, maintained their territories.

But this?

This was like someone had plugged a nuclear reactor directly into her nervous system.

The pleasure hit like a *tidal wave.*

Her nine tails flared golden. Her kimono flickered with foxfire. The meditation chamber—carefully warded, pristinely maintained—*cracked down the middle.*

"Ara?" she gasped, and then the second wave hit.

*Oh my.*

It wasn't just power.

It was *Death.*

The kind that made her ancient Youkai instincts scream warnings.

But also—and this was the concerning part—the kind that made something *else* in her respond.

Something primal.

Something that recognized a *predator* and thought "hmm, *interesting.*"

The ley lines carried the signature through her body. Into her spirit. Through her *essence.*

It was... *ara ara* didn't even begin to cover it.

"YASAKA-SAMA!"

Her attendants burst into the chamber. The youngest—a Nekomata named Kuroka's cousin (the extended Youkai family tree was *complicated*)—stopped dead.

"Yasaka-sama, are you—your tails are—the chamber is—"

"I'm *fine,*" Yasaka managed, forcing her tails to settle. Her breathing was uneven. Sweat beaded on her forehead. "What is the status of the ley lines?"

"Unstable, Yasaka-sama! Something has entered the network. Something with *immense* power."

"Location?"

"The signature is strongest in... Kuoh City."

Of course.

*Of course* it was Kuoh.

The city where Devil heiresses played Rating Games. Where ley lines converged like supernatural highways. Where apparently every crisis in Japan decided to hold conventions.

Yasaka stood, smoothing her kimono with shaking hands. "Prepare a delegation. We're going to Kuoh."

"Yasaka-sama, is that wise? The Devils—"

"The Devils are the *least* of our concerns." Her golden eyes glowed. "Whatever just manifested has direct access to Japan's ley lines. Which makes it *our* problem."

"What do you think it is?"

Yasaka remembered the sensation. Death and Dragon and something else—something that felt like *loneliness* so profound it had weight.

"I think," she said slowly, "it's someone very powerful and very, *very* lost."

"Should we be concerned?"

Yasaka's smile was complicated.

"Concerned? Perhaps. But also..." Her tails swished. "*Intrigued.*"

She didn't mention the other thing.

The way her body had *responded* to that presence.

The way every Youkai instinct screamed that whoever—*whatever*—had manifested...

They were going to change *everything.*

And possibly be very, *very* handsome.

A Kitsune could hope.

**[RANDOM ALLEY IN KUOH CITY]**

Right.

So.

I'd just crashed into a new dimension, acquired a sarcastic dragon roommate in my hand, grown wings made of existential dread, and apparently sent every supernatural entity within a hundred-mile radius a notification that read: "NEW PLAYER HAS ENTERED THE GAME."

And I sneezed.

Because *of course* I did.

My life is a sodding comedy sketch and I'm the only one who didn't get the script.

**[Kid,]** Vritra rumbled in my head—and let me tell you, having Clint Eastwood's voice narrating your thoughts is *weird*—**[why do I get the feeling we just became real popular?]**

"Because," I said to my gauntlet-covered hand (yes, I talk to my hand now, we've established I'm mental), "my life is a cosmic joke and the universe has a *terrible* sense of humor."

**[Can't argue with that.]**

I looked around the alley. Japanese characters everywhere—on signs, vending machines, what looked like a poster advertising something I couldn't read but involved a lot of exclamation points and a girl with improbably large eyes.

"Brilliant," I muttered. "Just *brilliant.* Survived the apocalypse, became Master of Death, got yeeted through dimensions, and landed in—" I squinted at a street sign. "—I have absolutely no idea where I am because I CAN'T READ JAPANESE."

**[You want help with that?]**

"Can you help with that?"

**[Kid, I'm a five-thousand-year-old Dragon King. I've been sealed, summoned, worshipped, and weaponized across half of Asia. You think I don't speak the local languages?]**

"...Can you teach me?"

**[I can do better than that. Hold still.]**

"Wait, what does 'hold still' mean—OH BLOODY HELL—"

It felt like someone poured hot sake directly into my brain.

Not painful, exactly.

Just *deeply uncomfortable.*

Knowledge flooded in. Characters. Grammar. Pronunciation. Cultural context that I definitely didn't ask for but apparently came with the package deal.

When it stopped, I was leaning against the alley wall, breathing hard.

"That," I gasped, "was *unpleasant.*"

**[You're welcome.]**

"I didn't say thank you."

**[You were thinking it.]**

"Was not."

**[Were too.]**

"This is already the worst roommate situation I've ever had, and I once shared a dorm with Ron Weasley, who kept a *rat* in his pocket for three years."

**[The rat was a person, wasn't it?]**

"...Yes."

**[Your world was *weird*, kid.]**

"Says the dragon currently living in my hand."

**[Fair point.]**

I pushed off the wall, testing my new language skills. Read a nearby sign.

*"Takoyaki—500 yen."*

"Huh. It worked."

**[Of course it worked. Now can we focus on the fact that every major supernatural faction in Japan just felt your arrival?]**

"About that." I paused. "Did someone just—" I made a vague gesture. "—you know. Through the ley lines?"

**[Kid, a nine-tailed Kitsune just had what I can only describe as a *spiritual experience* because your power signature hit her directly through the natural energy grid of Japan.]**

"That sounds like a 'me' problem that I'm going to ignore."

**[Healthy coping mechanism.]**

"I learned from the best." I looked down at the gauntlet. The runes were still crawling across the surface like they couldn't decide where they wanted to be. "So. Angels, Devils, and apparently amorous fox spirits. What else should I know about?"

**[Dragons. Gods. Youkai. Fallen Angels—they're different from regular Angels, don't ask. Various pantheons. The occasional Eldritch abomination. Your standard supernatural clusterfuck.]**

"Fantastic."

**[Oh, and High School.]**

I stopped walking.

"I'm sorry, what?"

**[This is Kuoh City. Major supernatural territory. Also home to Kuoh Academy, where a significant portion of the local supernatural community pretends to be students.]**

"You're telling me—" I turned slowly to look at what appeared to be a school building in the distance, "—that the Angels and Devils and whatnot are going to *high school?*"

**[Devil heiresses run the local territory through school clubs. It's efficient.]**

"It's *mental.*"

**[Says the guy who went to wizard boarding school.]**

"That was different! We weren't pretending! We were just... aggressively British about magic!"

**[Kid, I'm gonna be honest with you. This whole dimension runs on anime logic.]**

"On *what* logic?"

**[You'll figure it out. Usually involves a lot of yelling, power-ups in the middle of fights, and improbable bust sizes.]**

I stared at my hand. "Vritra-san—"

**[Don't call me that. Makes me sound like a salaryman.]**

"*Vritra*—are you telling me I've landed in some kind of... supernatural anime dimension?"

**[Technically it's a light novel series, but yes.]**

"And everyone's going to want to either recruit me or kill me?"

**[Probably both. Possibly at the same time.]**

"Brilliant. Just *brilliant.*" I ran my non-gauntleted hand through my hair. It was longer than I remembered. And black. Still black. Still messy. Some things transcended dimensions. "Right. Okay. I can work with this."

**[Can you?]**

"No. Not even remotely. But I'm going to pretend I can because the alternative is having a breakdown in an alley, and I've already had my breakdown quota for the century."

**[That's the spirit.]**

In the distance, sirens wailed.

Or maybe those were supernatural entities mobilizing to investigate the weird power spike.

Hard to tell.

"Vritra?"

**[Yeah, kid?]**

"This is going to get worse, isn't it?"

**[Kid, we haven't even hit hour one. *Much* worse.]**

"*Yabai,*" I said, testing out my new vocabulary.

**[Now you're learning.]**

I did what any sensible person would do when every major supernatural faction in Japan suddenly became aware of your existence:

I found a 24-hour convenience store.

---

## INSIDE THE KONBINI

The automatic doors chimed as I walked in.

The cashier—a tired-looking bloke who'd clearly worked one too many overnight shifts—looked up, saw me (gauntlet, weird wings that I'd *thankfully* managed to dismiss, general aura of "I've had a day"), and went right back to his phone.

"Welcome," he said in Japanese, utterly unbothered.

I loved him immediately.

"Cheers," I replied, also in Japanese, which was *still weird.*

The convenience store was bright. Aggressively bright. Like someone had decided that 2 AM needed the same lumens as the surface of the sun.

Rows of snacks. Drinks. Magazines with covers I definitely wasn't going to examine too closely. And—*thank God*—instant ramen.

I grabbed three cups. Curry flavor, because I was feeling adventurous.

**[Three?]**

"I haven't eaten proper food in fifty years. I'm getting three."

**[Fair.]**

I added onigiri. Pocky. Something that might have been a meat bun. A bottle of tea that promised to be "refreshing" in seventeen different fonts.

The cashier rang me up without comment.

"2,480 yen."

I reached for my wallet.

Which didn't exist.

Because I'd fallen through dimensional barriers and my wallet—along with everything else from my old dimension—was *gone.*

"Ah," I said intelligently. "Bollocks."

**[Kid. You're the Master of Death. You have a Longinus-class Sacred Gear. You literally made every supernatural entity in Japan sit up and pay attention. And you're worried about *money?*]**

"I can't just *steal* from the nice shopkeeper!"

**[Why not? You're already wanted by multiple factions.]**

"That's different! That's politics! This is *theft!*"

**[Your moral compass is *fascinating.*]**

The cashier was staring at me now.

Right.

I'd been having an argument with my hand.

In public.

"Sorry," I said. "Just—hang on—"

I looked at the gauntlet. At the runes crawling across its surface. At the concentrated cosmic power that apparently made Gods nervous.

"Can you... I don't know... *magic* me some money?"

**[Are you seriously asking me to counterfeit currency?]**

"I'm asking you to *help* me not look like a tosser!"

**[Fine. But you owe me.]**

"I owe a *dragon* who lives in my *hand?*"

**[Yes.]**

The gauntlet pulsed. Black and silver light flickered.

A wallet appeared in my other hand.

I opened it.

Japanese yen. A *lot* of Japanese yen.

"Where did this come from?"

**[Don't ask questions you don't want answered.]**

"Did you steal this?"

**[I *created* it. From ambient magical energy. It'll last about a week before it destabilizes.]**

"That's literally counterfeiting."

**[And?]**

I looked at the cashier. At the snacks. At my gauntlet.

"Sod it."

I paid.

The cashier handed me my change and a plastic bag without blinking.

"Thank you for your patronage," he said, monotone.

"Cheers," I said, and left.

## BACK IN THE ALLEY

I sat on a relatively clean bit of concrete, back against the wall, and opened the first ramen cup.

The smell hit me like a Memory Charm.

*God,* I'd missed food.

Real food. Not irradiated mystery meat. Not whatever I'd managed to scavenge from the ruins.

*Food.*

I added hot water from a thermos the shop had (brilliantly) provided, waited the requisite three minutes (longest three minutes of my life), and took the first bite.

It was *glorious.*

"Oh my God," I mumbled around noodles. "Oh my *God.*"

**[You're crying.]**

"Sod off, I'm not crying."

**[You're definitely crying.]**

"It's the *steam.*"

**[Sure it is, kid.]**

I ate in silence for a moment. Savoring it. Trying not to think about the last fifty years. About the loneliness. About watching everyone die over and over and—

Nope.

Not going there.

"So," I said, shoving those thoughts into the mental box labeled "DO NOT OPEN," "what's the play here?"

**[The play?]**

"Yeah. The play. The plan. The 'how do I survive in this new dimension without getting murdered by Angels or seduced by fox spirits' strategy."

**[First: don't get murdered. Second: the fox spirit thing might not be avoidable.]**

"Not helpful."

**[You want helpful? Fine. Here's the situation: You're a Longinus-class Sacred Gear user with power over Death. Every faction wants to either recruit you, study you, or eliminate you before you become a problem.]**

"Lovely."

**[The Devils will probably try to recruit you first. They're pragmatic. They'll offer you resources, protection, maybe a peerage position if you're lucky.]**

"A what?"

**[Devil nobility thing. Basically magical chess pieces that reincarnate you as a Devil and bind you to a master. It's complicated.]**

"Hard pass."

**[Smart. The Angels will want to observe you. Make sure you're not a threat to Heaven. They're less likely to attack outright but also less likely to help.]**

"And the Fallen?"

**[Azazel—their leader—will want to study your Sacred Gear. He's obsessed with them. Invented most of the modern ones. He's also surprisingly reasonable for a guy who rebelled against God.]**

"This is *barmy.*"

**[You haven't heard the best part yet.]**

"There's a *best* part?"

**[The Dragons.]**

Oh no.

"What about the Dragons?"

**[There are two other Longinus-class Dragon Sacred Gears in this city. The Boosted Gear—contains Ddraig, the Red Dragon Emperor. And the Divine Dividing—contains Albion, the White Dragon Emperor.]**

"And let me guess. They're going to want to fight me."

**[Ddraig will want to fight *everyone.* He's a battle maniac. Albion's more reserved but equally proud. And me?]** Vritra's voice took on a distinctly smug tone. **[I'm the one they *sealed* because I was too dangerous to kill.]**

"Fantastic. So I've got the equivalent of a nuclear weapon in my hand."

**[Kid, you're not the nuclear weapon. You're the guy who can *turn off* nuclear weapons. That's worse.]**

I finished the first ramen cup. Started on the second.

"Right. So. Recap: Multiple factions want me. Dragons want to fight me. I can't die but can definitely be imprisoned or sealed or otherwise inconvenienced."

**[Yep.]**

"And I'm eating convenience store ramen in an alley at 2 AM because it's the first actual food I've had in fifty years."

**[Also yep.]**

"And somewhere out there—" I gestured vaguely at the city, "—is a school full of Devils pretending to be teenagers."

**[Don't forget the perverts.]**

"I'm sorry, the *what?*"

**[Kuoh Academy has a notorious group of peeping toms. The Perverted Trio. They're legendary.]**

"This dimension is *mental.*"

**[You're just figuring that out now?]**

I ate more ramen. Tried to process.

Failed.

"Vritra?"

**[Yeah, kid?]**

"I think I need therapy."

**[Kid, we *all* need therapy. But therapy's for people who have time. We've got about—]** he paused, **[—six hours before the Devils send a delegation. Maybe three before the Fallen show up. Angels are harder to predict.]**

"How do you know that?"

**[I can feel them moving. Ley lines are like a giant supernatural GPS if you know how to read them.]**

"Of course they are." I finished the second ramen. Opened the third. "Right. Okay. New plan."

**[You have a plan?]**

"I'm going to finish this ramen. Then I'm going to find somewhere to sleep that isn't an alley. Then—*maybe*—I'll deal with the supernatural crisis."

**[That's a terrible plan.]**

"You got a better one?"

**[...No.]**

"Then shut it and let me eat."

I finished the third ramen cup in silence.

And tried very, *very* hard not to think about the fact that somewhere in this city, multiple factions were mobilizing.

Coming for me.

To recruit, study, or kill the weird dimension-hopping Master of Death who'd crashed into their world like a meteor made of poor life choices.

"Vritra?"

**[Yeah?]**

"This is going to be a *long* week, isn't it?"

**[Kid, you have *no* idea.]**

Somewhere in the distance, I heard wings.

Big wings.

"Oh *bollocks.*"

**[And so it begins.]**

I stood up, ramen cups abandoned, gauntlet glowing with black-and-silver light.

"Right then. Let's see which faction found me first."

**[My money's on the Devils. They're persistent.]**

"Brilliant. I've always wanted to meet actual Devils. Really rounds out the 'worst apocalypse survivor origin story' experience."

**[You're being sarcastic.]**

"I'm *always* sarcastic. It's a coping mechanism."

**[Fair enough. Ready?]**

I looked at my gauntlet. At the wings of void and shadow that spread from my back. At the power thrumming through me—Death and Dragon wound so tight they were basically the same thing.

"No," I said honestly. "Not even remotely."

**[That's the spirit.]**

And then I walked out of the alley.

Toward whatever fresh hell this dimension had prepared for me.

Because apparently, that's what Harry Potter does.

Even in new worlds.

Even with cosmic powers.

Even when he's *absolutely, completely, magnificently unprepared.
