OVERLORD Transmigration

Previously:

Izuku didn’t glance their way. His focus was locked on Bakugou, who was pushing himself up from the rubble, his gauntlets sparking erratically. Blood trickled from his temple, but his grin was feral. "About damn time you stopped pulling punches," he spat, flexing his fingers. The air around them crackled with the scent of nitroglycerin and ozone. Izuku exhaled, feeling the weight of his borrowed instincts—the ones Momonga had honed through endless and tireless nights.

NOW:

The first thing Izuku noticed was the smell—not decay, not blood, but stale air thick with the residue of old disasters. The USJ's dome stretched overhead like a ribcage picked clean by time, its artificial sky flickering between pale blue and static gray. He flexed his fingers, feeling the phantom weight of guild rings that weren’t there anymore. Some habits died harder than others.

Bakugou's voice cut through the silence like a detonation. "The hell is this?" He wasn’t asking about the architecture. Across the ruined plaza, figures emerged from the warp gate’s inky spill—not NPCs, not raid bosses, but living, breathing villains with quirks instead of class skills. Izuku’s pulse didn’t spike. That was the problem. Momonga’s instincts recognized the scenario: an ambush, predictable, almost nostalgic.

SUMMARY^1: Izuku, still carrying instincts from his time as Momonga, assesses the USJ's decayed state with eerie detachment. Bakugou reacts with aggression to their sudden displacement, while villains emerge through a warp gate—familiar yet different without game mechanics. Izuku remains unnervingly calm, recognizing the ambush through borrowed experience.

Thirteen was shouting evacuation orders, but Izuku was already moving toward the nearest cluster of students. His body remembered distances better than his mind did—three meters to Uraraka, five to Iida—and he positioned himself between them and the approaching thugs without breaking stride. One of the villains lunged, his arms elongating like rubber. Izuku sidestepped, grabbed the stretched limb, and used the man’s own momentum to slam him face-first into a shattered concrete slab. The crack of cartilage was louder than he expected.

"You—" A rasping voice from behind. Izuku turned just enough to see the knife aimed at his kidney. He didn’t block it. Let it land. The blade snapped against his reinforced uniform with a sound like a twig underfoot. The would-be assassin gaped. "Bullshit," he wheezed. Izuku kicked his legs out from under him and kept walking.

Aizawa was a whirlwind of capture scarf and precision strikes ahead, but the numbers weren’t adding up. Too many enemies, too many variables. Izuku’s fingers twitched toward a nonexistent staff. Then the warp gate pulsed again, and the air went thick with the promise of something worse.

SUMMARY^1: Izuku instinctively protects classmates by neutralizing attackers with effortless precision, his reinforced uniform deflecting a knife strike. While Aizawa fights ahead, the situation escalates as the warp gate reactivates, signaling impending danger.

The warp gate convulsed like a dying star, its edges fraying into tendrils of black mist. A hush fell—even the villains hesitated, their instincts screaming before their brains caught up. Then the pressure hit, a gravitational wave that sent dust spiraling upward in reverse. Izuku’s knees locked. He knew that presence. Not the stench of decay or cheap theatrics, but the quiet, inevitable weight of a world bending to someone’s will.

A boot clicked against rubble. The sound shouldn’t have carried, but it did, crisp as a gunshot. Tomura Shigaraki stood there, scratching his neck absently, his eyes scanning the students with the disinterest of a gamer scrolling through NPC dialogue. Then his gaze landed on Izuku. Stopped. His fingers stilled. "Huh," he said, voice cracking like dry kindling. "You’re not supposed to be here."

Izuku didn’t answer. He was too busy counting heartbeats—his own, steady at 60 bpm; Uraraka’s, rabbit-fast behind him; Aizawa’s, somewhere in the chaos, skipping every third beat from exhaustion. The math was off. Shigaraki’s fingers twitched toward his face, and Izuku moved before the command left his lips. He grabbed Uraraka’s wrist and yanked her sideways as the ground where she’d stood crumbled into dust.

"Interesting," Shigaraki murmured. His head tilted, red eyes gleaming through the fingers of the hand mask. "You didn’t even look. How’d you know?"

SUMMARY^1: Shigaraki emerges with overwhelming presence, immediately fixating on Izuku with unsettling recognition. Izuku, hyper-aware of allies’ vitals, preemptively saves Uraraka from decay without visual cues, provoking Shigaraki’s intrigued scrutiny.

Izuku exhaled through his nose. He could lie. Should lie. But Momonga’s instincts coiled in his ribs, restless. "Pattern recognition," he said. "You always lead with Decay on the right."

Silence. Then Shigaraki laughed—a sound like glass breaking. "Oh, that’s *good*." He took a step forward. The Nomu landed behind him with a wet thud, its exposed brain pulsing. "Let’s see if you know this one."

Aizawa’s scarf lashed out, aiming for Shigaraki’s throat. The Nomu moved faster, intercepting the fabric with a hand that could crush steel. Erasure activated—but the Nomu didn’t falter. Its regeneration kicked in before Aizawa’s quirk could take hold. Izuku saw the exact moment Aizawa realized his mistake.

"Don’t!" Izuku shouted. Too late. The Nomu backhanded Aizawa into a pillar hard enough to crack stone. Izuku’s fingers spasmed. His HUD—no, his *vision*—flared with damage assessments he hadn’t programmed. Aizawa’s ribs: two fractures, maybe three. Blood loss: 12% and climbing.

Bakugou’s explosions lit up the periphery, keeping the lesser villains at bay. "Deku!" he snarled. "Plan. *Now*."

Izuku’s mouth was dry. He had no staff. No spells. Just a body that remembered being more than human and a mind that knew exactly how outmatched they were. Then he saw it—the warp gate, still active, its edges shimmering where Kurogiri’s control frayed under the Nomu’s presence.

"Uraraka," Izuku said, low and urgent. "When I say *now*, float me."

She nodded, fingers twitching. Shigaraki was strolling toward them now, humming tunelessly. The Nomu flexed its claws.

Izuku crouched, coiled, and prayed his borrowed strength would hold.

The Nomu lunged.

"*Now.*"

Uraraka’s fingertips brushed his shoulder. Weightlessness hit like a drug. Izuku kicked off the ground—not forward, but *up*, straight into the Nomu’s path. At the apex, he twisted, grabbed the beast’s wrist, and let momentum do the rest. The Nomu’s own force carried them both backward, straight into the warp gate’s event horizon.

Shigaraki’s scream was pure static. "NO—!"

Then the gate swallowed them whole.

The darkness tasted like ozone and iron. Izuku’s lungs burned—not from exertion, but from the absence of anything *to* burn. The Nomu’s wrist was still clamped in his grip, its regeneration struggling against the void’s hunger. For a heartbeat, they hung suspended in the nothingness, two puppets with severed strings. Then gravity reasserted itself with a vengeance.

They crashed through the ceiling of what might’ve been a tavern in another life. Wood splintered. Plaster rained down. Izuku rolled to his feet, coughing dust from his throat, and barely dodged the Nomu’s retaliatory swipe. Its talons sheared through a support beam like butter. The building groaned. Outside, voices shouted in a language that prickled the back of Izuku’s skull—*familiar*, but wrong, like a song played half a step off-key.

The Nomu lunged again. Izuku pivoted, driving his elbow into its ribs. Bone gave way with a wet crunch, but the creature didn’t stagger. Its wounds knit themselves shut before Izuku could follow up. He backpedaled, scanning the room for anything resembling a weapon. A broken chair leg. A shattered tankard. *Pathetic.* Momonga’s instincts supplied a dozen spells he couldn’t cast.

Then the door burst open.

“What in the—*augh!*” The man who’d entered barely had time to register the Nomu before it grabbed him by the face and flung him through the wall. More shouts erupted outside. Izuku didn’t wait. He dove through the new hole, landing in a marketplace in chaos. Stalls overturned. People running. And towering over them, a figure in obsidian armor, his greatsword already drawn.

“*You*,” the knight growled, helm tilting toward the Nomu. “Who dares bring abominations into my city?”

Izuku didn’t answer. He was too busy recognizing the crest on the knight’s pauldron—the symbol of the Baharuth Empire. His stomach dropped. *Not just isekai’d. Isekai’d wrong.*

The Nomu didn’t care about geopolitical crises. It charged. The knight met it mid-stride, his sword cleaving through its shoulder with a spray of black ichor. The Nomu screeched, regenerating instantly, and lashed out. The knight blocked with his vambrace, but the force sent him skidding backward.

Izuku moved. He snatched a fallen dagger from the cobblestones and drove it into the Nomu’s spine. No effect. The creature backhanded him into a fruit cart. Something in his ribs *clicked*. Pain flared, sharp and bright—human pain, not the dulled feedback of an avatar. He gritted his teeth. *Think. Adapt.*

The knight was regrouping, his sword humming with a faint blue light. Magic? No—*martial arts*. Izuku’s mind raced. If quirks didn’t exist here, the Nomu’s regeneration might’ve been designed with Erasure in mind. But without Aizawa’s quirk to nullify it…

“Oi, tin can!” Izuku yelled. The knight’s head jerked toward him. “Its brain! Aim for the—”

The Nomu spun, faster than should’ve been possible, and punched a hole through the knight’s chestplate.

Silence. The knight coughed, blood speckling his visor. Then he grinned. “*Finally*,” he wheezed, and drove his sword through the Nomu’s exposed cerebellum.

The creature spasmed. Its limbs twitched erratically, like a puppet with half its strings cut. Then it collapsed, motionless.

Izuku exhaled. The knight yanked his blade free and promptly keeled over.

“...Shit.”

A shadow fell over him. Izuku looked up. A woman in a cleric’s robe loomed, her staff glowing an ominous gold. “You,” she said sweetly, “are going to explain *everything*.”

Behind her, the marketplace’s survivors were forming a very concerned, very armed semicircle.

Izuku swallowed. “Ah.”

Somewhere in the distance, a dragon roared.

The cleric's staff hummed against Izuku's sternum, pressing just hard enough to promise broken ribs if he moved wrong. Up close, her smile had too many teeth. "Start talking," she said, "or I start breaking things."

Izuku's ribs throbbed in agreement. Behind her, the crowd's mutters sharpened into distinct threats—*"spy," "demon summoner," "Bahamut's balls, did you see that thing's face?"*—none of which helped his case. He exhaled through his nose. Momonga's instincts whispered *diplomacy first*, but the only words that came were, "I'm as lost as you are."

The staff glowed hotter. "Try again."

"*Literally.*" Izuku gestured at the Nomu's corpse, its flesh already bubbling into black sludge. "That thing chased me through a—" He bit down on *warp gate*. These people wouldn't know Kurogiri from a hole in the ground. "A portal. I didn't bring it here."

The knight groaned from where he'd face-planted in the mud. "Liar," he slurred, pushing himself onto one elbow. His breastplate gaped open, revealing a mess of muscle and shattered bone that should've killed him instantly. "That abomination reeked of *magic*—and so do you."

Izuku's pulse hiccuped. *Magic.* Not quirks. The distinction mattered. He glanced at his hands—no Guild Rings, but the calluses were all wrong, too smooth for someone who'd supposedly trained his body to the brink. His stomach twisted. *I'm not even in my own skin.*

The cleric followed his gaze. Her nostrils flared. "Interesting," she murmured. Then, louder: "Bind him. The Emperor will want to interrogate this one personally."

Hands grabbed Izuku's arms. He let them. Resisting now would only cement their suspicions—and with the knight's sword still dripping Nomu gore, he wasn't keen on testing their patience.

As they dragged him upright, something clattered from his pocket. A coin. No—*a Guild Piece*. Izuku's breath caught. It was duller than he remembered, its edges worn smooth by time, but the symbol was unmistakable: Ainz Ooal Gown's crest.

The cleric snatched it up before he could react. Her eyes widened. "Where did you get this?"

Izuku opened his mouth—and the sky *screamed*.

Every head jerked upward. A shadow blotted out the sun, vast as a thunderhead, wings spread like the end of the world. The dragon circled once, then plummeted toward the marketplace with the grace of a falling guillotine.

"*DOWN!*" the knight roared.

The crowd scattered. Izuku hit the dirt as the dragon landed with enough force to shatter cobblestones. Its scales gleamed like polished obsidian, each one etched with runes that hurt to look at. The cleric's staff clattered to the ground, her fingers spasming around the Guild Piece.

The dragon's head swung toward her. "*That*," it rumbled, "*is not yours.*"

Its tail lashed out. The cleric flew backward, skidding through a merchant's stall in a hail of splinters and silk. The Guild Piece tumbled through the air—straight into Izuku's outstretched hand.

Heat seared his palm. The crest glowed crimson, pulsing in time with his heartbeat. A voice that wasn't his own whispered through his skull: *"Player detected."*

The dragon's nostrils flared. It leaned in, close enough that Izuku could count the serrated edges of its teeth. "*Ah,*" it breathed. "*You.*"

Izuku's mouth went dry. "Do I... know you?"

The dragon laughed—a sound like boulders grinding together. "*Not yet.*" Its claw closed around him, careful as a jeweler handling a precious stone. "*But you will.*"

The marketplace blurred. Wind howled past Izuku's ears as the dragon launched skyward, its wings beating hard enough to uproot trees. Below, the knight's curses faded into the distance.

Izuku clutched the Guild Piece tighter. It burned now, branding his flesh with the mark of a guild that shouldn't exist here.

The dragon's voice cut through the chaos: "*Hold on, little player. This will hurt.*"

Then it banked sharply—straight into a stormfront of crackling violet energy.

Izuku had exactly half a second to think *oh shit* before the lightning hit.

The lightning didn’t kill him. That was the first surprise. It *should* have—crackling violet tendrils wrapping around his limbs, searing through muscle and bone with the precision of a scalpel. Instead, the energy *pulsed*, synchronizing with the Guild Piece’s crimson glow. Izuku’s vision whited out. When it cleared, the dragon was gone, replaced by an endless void where gravity had no meaning. He floated, weightless, surrounded by fragments of broken architecture—a crumbling tower here, a shattered bridge there—as if someone had dropped a world and forgotten to pick up the pieces.

A voice echoed from everywhere and nowhere at once: **"Authorization required."**

Izuku’s fingers convulsed around the Guild Piece. The burn had spread up his forearm now, etching Ainz Ooal Gown’s crest into his skin like a brand. He gritted his teeth. "Let me out."

**"Insufficient permissions."** The void rippled. Shapes emerged from the darkness—figures in tattered robes, their faces obscured by shifting static. One stepped forward, its voice a distorted whisper: *"Player Midoriya Izuku. Guild affiliation: Ainz Ooal Gown. Last login: 2138. Time discrepancy detected."*

Izuku’s breath hitched. *2138?* That was centuries before his birth. Before quirks. Before *everything*. "What is this?"

The static figure tilted its head. *"Emergency protocol. Guild assets cannot be left unclaimed."* It gestured to the floating ruins. *"Your guildhall awaits."*

A city materialized beneath him—Nazarick’s spires, but wrong. Smaller. Human-sized. The Tomb of Nazarick, scaled down to fit a world without magic, its defenses stripped bare. The static figure pointed to the central tower. *"The Throne Room holds your answers."*

Izuku’s legs moved before his brain caught up. The ground solidified underfoot, cold marble biting through his soles. The doors to the throne room loomed ahead, carved with familiar runes. He pushed them open.

Inside, a single figure sat slumped on the throne—skeletal fingers steepled, red pinpricks of light flickering in hollow eye sockets. Momonga. No—*Ainz*. But not the Ainz Izuku knew. This one’s armor was cracked, his cape frayed, as if he’d been waiting for centuries.

The skeleton’s jaw creaked open. **"Ah. You’re early."**

Izuku’s throat tightened. "Early for *what*?"

Ainz chuckled, the sound like dry bones rattling. **"The reckoning, of course."** He gestured to a rusted mirror propped against the throne. **"Look."**

The glass didn’t reflect. It *showed*—UA’s ruins, smoke curling from collapsed buildings, a skyline Izuku knew by heart twisted into something grotesque. Pro Heroes lay broken in the streets. Bakugou knelt in the wreckage, his gauntlets shattered, blood dripping from his chin as Shigaraki loomed over him with all five fingers extended. Uraraka was screaming. Aizawa wasn’t moving.

Izuku recoiled. "This isn’t happening."

**"Yet,"** Ainz corrected. He tapped the mirror’s frame. Rust flaked away, revealing more scenes—Japan’s cities reduced to graveyards, oceans boiling under a black sun, Nomu with wingspans like skyscrapers blotting out the sky. **"Your world lacks the levels to resist them. Without Nazarick’s defenses, without *players*—"**

"Bullshit." Izuku’s hands shook. "Quirks can—"

**"Quirks are *glitches*."** Ainz’s voice cut like a guillotine. **"The system wasn’t designed for them. And now *they*’ve noticed."** The mirror’s surface rippled, revealing a figure wreathed in shadows—tall, faceless, its outline pixelating at the edges. Data corruption given form.

Izuku’s Guild Piece burned hotter. "What is that?"

**"The Admin."** Ainz’s eye lights guttered. **"Or what’s left of one."**

The static figures reappeared, circling the throne. One spoke, its voice layered with a hundred others: *"Guildmaster Momonga designated you successor. Authorization pending."*

Izuku’s laugh bordered on hysterical. "I’m not even level 100!"

**"Levels don’t matter here."** Ainz leaned forward. **"This isn’t Yggdrasil. It’s the *back end*—the code that runs beneath reality. And right now, your world is a bug about to be patched out."**

The mirror cracked. Shigaraki’s grin split the glass, his fingers brushing the surface like he could reach through. The Admin’s shadow loomed behind him, tendrils creeping into his veins.

Ainz stood abruptly. **"Decision time."** His cloak billowed, revealing a rift swirling beneath the throne—a gateway back to the marketplace, the dragon, the waiting empire. **"Stay here, claim the guild, and fight a war you aren’t ready for."** Another rift opened, showing UA’s cafeteria, the chatter of students oblivious to the coming storm. **"Or go back, play hero, and die with the rest."**

Izuku’s mouth tasted like copper. "There’s a third option."

Silence.

He grabbed the mirror’s largest shard. "You said this was the back end. That means I can *edit* things."

The static figures recoiled. *"Unauthorized access—"*

"*Override.*" Izuku slammed the shard into his Guild Piece. Crimson light erupted, searing his vision. The void shattered into cascading code—lines upon lines of commands, variables, *player IDs*. He saw All Might’s name tagged [HERO: DEPRECATED], Shigaraki’s crawling with [ERROR: CORRUPTED], and his own, flickering between [QUIRKLESS] and [PLAYER: ADMIN].

Ainz’s laughter echoed through the chaos. **"Oh, *that’s* cheating."**

Izuku ignored him. He scrolled frantically until he found it—the root file, the one labeled [WORLD SEED: EARTH-2149]. His fingers hovered over the delete key.

The Admin’s shadow surged from the mirror, swallowing the throne whole.

*No more time.*

Izuku input a new command instead: **[FUSION: EARTH-2149 & NEW WORLD]**

The void screamed. The throne room dissolved. Ainz’s skeletal hand clasped his shoulder, voice barely audible over the crashing code—

**"Wake up."**

—Izuku gasped awake on cold marble, the dragon’s claws still wrapped around him. The marketplace lay in ruins below. The cleric groaned into consciousness nearby, her eyes widening at the sight of him.

The dragon’s grip tightened. "*What,*" it hissed, "*did you do?*"

Izuku looked down. His Guild Piece was gone, replaced by a tattoo—the crest of Ainz Ooal Gown, throbbing with every heartbeat.

Far above, the sky flickered. For half a second, UA’s silhouette bled through the clouds—smoke and broken glass superimposed over the marketplace’s wreckage. Then it was gone, leaving only the dragon’s labored breathing and the scent of charred meat.

The cleric scrambled backward, her staff forgotten. "Emperor’s mercy," she whispered. "What *are* you?"

Izuku flexed his tattooed hand. The dragon’s claws trembled around him, its scales dulling where they touched his skin. Energy siphoned. *Not me*, he realized. *The crest.*

"Put me down," he said.

The dragon recoiled as if scalded. Its wings faltered. They dropped like stones, crashing through a thatched roof into a hayloft thick with dust. Izuku rolled to his feet, hay sticking to his sweat-slick skin. The dragon—smaller now, barely larger than a warhorse—hissed through needle-sharp teeth. "*You overwrote the partition.*" Its voice had lost the reverb of divinity, cracking like cheap theater. "*That’s impossible.*"

Izuku’s tattoo pulsed. A notification flickered at the edge of his vision—**[SYNCHRONIZATION: 12%]**—in Yggdrasil’s crisp font. He blinked. It didn’t disappear.

Outside, the cleric’s voice rose in a chant. Golden light seeped through the cracks in the wall. The dragon sneered. "*Foolish child. You’ve stranded us between two dying worlds.*" It lashed its tail, sending up a storm of chaff. "*Enjoy your last breaths.*" Then it *twisted*, folding inward like origami, until only a smoking sigil remained on the floorboards.

Izuku didn’t have time to process that. The hayloft’s door burst open, revealing the knight—his chestplate hastily repaired with what looked like tavern napkins and sheer spite. Blood matted his beard, but his sword gleamed with fresh polish. Behind him, a dozen crossbows clicked in unison.

"Last chance, demon," the knight growled. "Speak plain. Did you call that wyrm?"

Izuku’s tattoo burned hotter. **[SYNCHRONIZATION: 17%]**. He exhaled through his teeth. "It called *me*."

The crossbows creaked. The knight’s eye twitched. Then, from the street below, a new voice cut through the tension—brittle, amused, and horribly familiar.

"My, my. What a mess."

Every soldier froze. The knight paled. Even the cleric’s chanting stuttered.

Izuku knew that voice.

He lunged for the hayloft’s window just as the knight bellowed, "DOWN, ALL OF YOU—"

The wall exploded.

Splinters rained like shrapnel. Izuku hit the cobblestones rolling, his ears ringing. When he looked up, a figure stood amid the rubble—tall, impeccably dressed, crimson eyes gleaming behind a monocle. His smile was a scalpel’s edge.

"Ah." Albedo’s gaze settled on Izuku. "There you are."

The knight swung first. His greatsword arced toward Albedo’s spine with enough force to cleave stone. It shattered on contact.

Albedo didn’t turn. "How *rude*." She flicked a finger. The knight rocketed backward through three buildings.

Izuku’s tattoo flared—**[SYNCHRONIZATION: 24%]**—as Albedo stepped closer. Her heel crushed the dragon’s sigil to ash. "You’ve been very naughty," she murmured, cupping Izuku’s chin. Her gloves were softer than they had any right to be. "Merging worlds? Without *permission*?"

Izuku swallowed. "You’re not real."

Albedo’s laugh was a bell’s chime. "Oh, darling. Nothing here is." She plucked a silver pocketwatch from her vest. The face showed no numbers—only a pulsing red **[ERROR]**. "But that won’t save you."

The watch clicked.

Izuku’s vision split—the marketplace overlaying UA’s entrance gate, Albedo’s smile melting into Shigaraki’s sneer. Pain spiderwebbed through his skull. He tasted copper, ozone, *static*.

Albedo’s voice cut through the noise: "Run."

He ran.

Crossbow bolts hissed past his ears. The cleric’s golden light lanced overhead, searing a stall to cinders. Izuku dodged sideways, vaulting a collapsed cart, and nearly collided with a figure in a hooded cloak.

The cloaked figure moved before Izuku could react—one hand snapping out to grip his wrist, the other pressing a dagger to his ribs. "Not that way," a woman's voice hissed. Her breath smelled of gunpowder and mint. "Unless you *want* to be Albedo's new footstool."

Izuku's tattoo pulsed a warning. **[SYNCHRONIZATION: 31%]**. The dagger's tip pricked through his uniform. "Who—?"

"Shut up." She yanked him into a narrow alley, where the shadows clung thick as tar. Behind them, the marketplace erupted in screams—the wet *thunk* of flesh meeting armor, the sizzle of spells gone awry. The woman didn't look back. She dragged Izuku through a maze of backstreets, her boots silent on the cobblestones.

They skidded to a halt at a dead end. The woman whipped around, her hood falling back to reveal close-cropped silver hair and a scar that split her left eyebrow clean in half. "Show me the crest," she demanded.

Izuku hesitated. Her dagger twitched.

"*Now.*"

He rolled up his sleeve. The Ainz Ooal Gown tattoo glowed faintly, its edges shimmering like wet ink. The woman exhaled sharply. "Shit. You really *are* him." She sheathed her dagger and slapped a rusted manacle around his wrist. The metal hissed, clamping down with a sound like a lock engaging. **[SYNCHRONIZATION: 29%]**. The percentage *dropped*.

Izuku jerked his arm back. "What did you—?"

"Insurance." She grabbed his collar and shoved him toward the wall—which wasn't a wall at all, but a painted illusion. His shoulder passed through the brick like mist. "Move. She'll scent you soon."

Beyond the false wall stretched a cavern lit by bioluminescent fungi. The air reeked of damp earth and something sharper—ozone, again, but layered with the acrid tang of alchemical reagents. A workbench dominated the center of the room, littered with half-disassembled artifacts Izuku recognized from Yggdrasil: a fractured Gate Stone, a ring of Lesser Resistance missing its gem, and—

His breath caught. A Guild Ring. Cracked, but unmistakable.

The woman followed his gaze. "Yeah. We've been collecting what's left." She kicked the manacle's chain, which trailed back to an iron spike driven deep into the stone. "Sit. You're not the first player to wash up here."

Izuku's fingers brushed the Guild Ring. A static shock leapt from the metal to his tattoo. **[SYNCHRONIZATION: 34%]**. The jump was sharper this time, like the system was recalibrating. "How many others?"

"Enough to know that crest's a death sentence." She tossed a canteen at his feet. "Drink. You're leaking mana like a sieve."

The water tasted of iron and lemon. Izuku's vision swam for a heartbeat—then cleared, sharpening to impossible detail. The cavern's shadows resolved into lines of drifting code, the fungi pulsed with health-bar green, and the woman...

Her stats hovered above her head in crisp white text:

**[??? - Level 87  

Class: Rogue Artificer  

Affiliation: Independent (Formerly: Ainz Ooal Gown)**

Izuku's canteen hit the floor. "You're a *player*."

"Was." She peeled back her sleeve to reveal a tattoo far older than his—the crest faded to gray, its edges scarred over. "This world *eats* us. Drains us dry until we're just... ghosts with fancy titles." She tapped her manacle. "That slows it down. Not much. But enough."

A tremor shook the cavern. Dust rained from the ceiling. Somewhere above, Albedo's laughter echoed through the streets, sweet as poisoned honey.

The woman's jaw tightened. "She's close." She snatched a satchel from the bench and threw it at Izuku. Inside: a tarnished silver dagger, three vials of cerulean liquid, and a cracked monocle. "Take these. The dagger's got one charge left—Dimension Slash. Use it on the eastern gate's guards. The potions are mana blooms. They'll burn like hell, but they'll jack your sync rate long enough to—"

Another tremor. Closer. The cavern's entrance collapsed in a shower of rubble.

Albedo's voice purred through the dust: "Little mouse~ You stole something of mine."

The woman paled. She grabbed Izuku's shoulders. "Listen carefully," she hissed. "The eastern gate leads to the ruins of Carne Village. Find Enri—tell her 'the pumpkin moon rises twice.' She'll—"

A section of the cavern wall dissolved into golden dust. Albedo stepped through, her pristine dress untouched by debris. She tsked. "Naughty little thieves." Her gaze locked onto Izuku's manacle. "Oh, clever girl. Too bad it won't help."

The woman shoved Izuku backward into a fissure he hadn't noticed—narrow, barely wider than his shoulders. "GO!"

Albedo's hand shot out. The woman intercepted it with her dagger. The blade shattered on contact, but the distraction bought Izuku half a second to squeeze into the crevice. He barely dodged the whip-crack of Albedo's tail as it gouged the rock where his head had been.

The tunnel twisted downward sharply. Izuku slid more than ran, jagged stone tearing his uniform. Behind him, the woman screamed—not in pain, but in raw defiance. A detonation shook the earth, followed by Albedo's enraged shriek. Then silence.

Izuku's manacle vibrated against his wrist. The sync rate flickered: **[SYNCHRONIZATION: 41%]**. He stumbled into a subterranean river, its black water stinking of sulfur. The satchel had survived, barely. He fumbled for the cracked monocle.

The world shifted into wireframe. Hidden paths glowed blue beneath the water's surface. One led to a crumbling archway marked with three overlapping circles—the eastern gate's sigil. Izuku waded in, the icy current numbing his legs.

Something brushed his ankle. A hand. No—dozens of hands, skeletal and grasping, rising from the depths. **[WRAITH SENTRIES - LEVEL 32]**. Their jaws gaped soundlessly.

Izuku jammed the monocle onto his nose. The overlay pulsed red, highlighting weak points. He kicked, his heel connecting with a wraith's temple. It dissolved into smoke. The others recoiled.

He surfaced gasping at the archway. The gate was sealed with a rusted portcullis, its bars too narrow to squeeze through. Izuku's fingers found the silver dagger. One charge left.

A wraith's claws raked his back. Pain flared hot and sudden. He spun, driving the dagger upward in a desperate arc. Space itself split along the blade's path—a jagged violet tear that swallowed the wraiths whole. The portcullis sheared apart with a metallic scream.

Izuku lunged through just as the rift collapsed behind him. He emerged into blinding daylight, rolling down a grassy slope. The dagger crumbled to dust in his grip.

He lay panting at the edge of a wheat field. The eastern gate's ruins loomed behind him, now half-submerged in the riverbank. Ahead, smoke curled from the chimneys of a village that shouldn't exist—not here, not now. Carne. But not the Carne from Yggdrasil. This one had UA's broken clock tower jutting from its central square like a knife wound.

His tattoo burned. **[SYNCHRONIZATION: 53%]**. The fusion was accelerating.

A child's voice piped up: "Mister, you're bleeding."

Izuku looked down. A girl no older than six stood there, holding a basket of wildflowers. Her stats read **[ENRI - LEVEL 1]**, but her eyes held centuries of weariness.

He swallowed blood. "The pumpkin moon rises twice."

Enri's smile didn't reach her eyes. "Took you long enough." She plucked a petal from her basket and pressed it to his wound. It stuck like a bandage, glowing faintly. "Come on. The others are waiting."

"Others?"

She pointed to the village. Figures moved in the shadows—some armored, some robed, all bearing the ghostly afterimage of player tags above their heads. The last survivors of Ainz Ooal Gown.

One stepped forward, his crimson cloak fluttering in a wind that didn't exist. The hood shadowed his face—except for the grin. Too wide. Too many teeth. **[PAULDRON - LEVEL 94. CLASS: BERSERKER CLERIC. STATUS: CORRUPTED]**. His voice rasped like nails on slate: "Well well. The guild's favorite chew toy finally shows up."

Izuku's fingers twitched toward the satchel's remaining vials. "You're not Pauldron." The real one had died years before Yggdrasil's shutdown—screaming into voice chat as his avatar dissolved in the Sixth Floor's acid traps.

The figure chuckled. "Neither are you." He flicked his wrist. A health bar materialized above Izuku's head, half-empty and pulsing erratic crimson. "Look at that sync rate. You're glitching *hard*, kid."

Enri tugged Izuku's sleeve. "Don't mind him. He's always cranky after respawns." She pointed to the village's central well, where the water shimmered with unnatural violet hues. "The others are downstairs."

Downstairs turned out to be a cavernous sublevel beneath the well—part Yggdrasil dungeon, part UA maintenance tunnel, the walls a patchwork of medieval brick and reinforced concrete. The air hummed with displaced magic, prickling Izuku's skin like static.

A woman materialized from the shadows, her form flickering between a sleek hero costume and flowing mage robes. **[MOMOKO - LEVEL 89. CLASS: PHANTOM ARCHER. STATUS: STABILIZING]**. She tossed Izuku a rusted canister. "Drink. Before your code unravels completely."

The liquid tasted like battery acid and nostalgia. His sync rate spiked to **[67%]**, overlays blooming across his vision—Yggdrasil's UI grafting onto UA's shattered skyline. He glimpsed the ghostly outlines of his classmates mid-battle, frozen in time like a corrupted save file.

Pauldron leaned against a crumbling pillar. "Here's the fun part." He tapped the wall. The stone dissolved, revealing a pulsating rift where two worlds ground against each other like broken gears. "Your little fusion hack? It's tearing both realities apart at the seams."

Through the rift, Izuku saw it—UA's courtyard buckling under the weight of a medieval siege tower, the Nomu's corpses twitching with necrotic magic. Shigaraki stood atop the rubble, his right hand fused with Albedo's obsidian gauntlet. They turned in unison, their mismatched eyes locking onto Izuku through the dimensional divide.

Momoko's bow materialized in her hands. "We've got maybe ten minutes before that rift widens enough for them to crawl through." She nocked an arrow made of condensed starlight. "So. Plan?"

Enri piped up: "The Pumpkin Moon."

The veterans froze. Pauldron's grin vanished. "No. That's a *guild* ritual. We're not—"

"We're all that's left of the guild," Momoko interrupted. She nodded to Izuku's tattoo. "And he's carrying the crest."

Izuku's stomach dropped. Guild rituals required two things: a World Item, and eight original members. They had neither. Just six half-dead players and a child who shouldn't exist.

Enri pressed her tiny hand against the rift. The skin peeled back, revealing circuitry beneath. "I'm more original than you think." Her voice deepened, glitching between frequencies. **[SYSTEM OVERRIDE: ADMINISTRATOR PRIVILEGES DETECTED.]**

The cavern shook. Albedo's talons punched through the rift, each claw tip dripping molten code. Shigaraki's fingers curled around the edges, decay spreading in jagged pixelated patterns.

Pauldron spat blood. "Fuck it." He ripped a pendant from his neck—a tiny pumpkin charm that pulsed with sickly orange light. "World Item: Harvest Moon. Last charge." He tossed it to Izuku. "You're calling the ritual, newbie."

The charm burned in Izuku's palm. Guild protocol flooded his mind—chant requirements, mana channels, the precise tonal harmonics needed to stabilize dimensional collapse. But rituals also required *sacrifice*.

Momoko nocked another arrow. "We'll buy you time." Her form solidified into full armor, UA's insignia merging with Yggdrasil's crest. "Just scream real loud when you're ready."

They charged the rift without hesitation. Izuku barely had time to process Enri's small hands guiding his into the correct mudra—left pinky crossed over right thumb, guild-sign for *temporary authority*—before the cavern erupted in spellfire.

The charm's glow intensified. His sync rate hit **[89%]**, the tattoo searing through muscle to bone. Through the pain, Izuku heard it—the ritual's opening verse, whispered by forty-one voices long turned to dust:

*"By blood and byte we bind thee—"*

The rift screamed. The sky cracked. And far away, in two worlds ending, a dragon laughed.
