Transmigrated into Fairy Tail with a ChatGPT

Ryan's first night back from Caelum's Rest was supposed to be peaceful.

Instead, he woke up in a cold sweat, eyes wide, breath ragged.

The dream had been too real—white space, floating error windows, an infinite void, and a shadowy voice whispering code in reverse. Somewhere in the haze of it, something watched him. Not Fairy Tail. Not Earth Land.

Something older.

"Wonderful," Ryan muttered, rubbing his eyes. "It's not even breakfast and I'm being hacked."

Fairy Tail Guild Hall – Morning

As usual, someone had already smashed a table.

"Gray, put on some clothes!" Lucy shouted from across the room.

Cana was drinking. Natsu was asleep upside-down on the rafters. Elfman was declaring a potted plant manly.

Just another day.

Ryan made a beeline for Makarov's office.

The Guild Master, all 3 feet of terrifying power, was floating on a magic cushion behind his desk, reading a newspaper.

He didn't even look up when Ryan knocked.

"I heard you survived a job with Lucy," Makarov said. "Did you break anything expensive?"

"No. Just almost got deleted by a malware beast. No big deal."

Now the old man looked up.

"Explain."

Debrief with the Master

Ryan told him everything—from the glitched creature to the system alerts to the weird dreams. He left out the "I'm from another world" part. For now.

Makarov listened in silence, arms crossed.

When Ryan finished, the old man leaned forward. "Scriptweaver Magic isn't native to this world. And magic that uses logic syntax? That's technology masquerading as sorcery."

> [ChatGPT]: Note: That was a compliment and a veiled threat.

Ryan chuckled nervously. "So I'm... an anomaly?"

"Let's call you a 'feature' for now," Makarov said. "But keep your guard up. If something is reaching across dimensions to find you, then your presence here might have consequences."

Ryan frowned. "You think it's connected to why I transmig—uh, arrived here?"

Makarov smiled faintly. "I think it's time we ran a diagnostic on you."

The Sync ended with a sharp jolt, sending Ryan stumbling back.

"I know how this works," he muttered. "Cool upgrades… and something bad's coming."

Lucy & the Rift

Later that afternoon, Lucy dragged Ryan into a side street.

"Did your system pick up anything weird just now?"

"Define 'weird,'" Ryan said.

She held up her Celestial Key—it shimmered, flickering between solid and translucent. The space around it bent like heat waves in the air.

> [ChatGPT]: Rift Detected – Minor Dimensional Bleed

Source: Astral Plane interference

Severity: Moderate

Signature: Celestial Gate Distortion

"Oh no," Ryan whispered. "It's spreading."

From the cracked cobblestones, a thin thread of glowing black code rose into the air—and suddenly, a shape tore out of it.

It looked like a shadow version of Virgo, twitching, fragmented, eyes glowing like broken data.

"Ryan!" Lucy shouted. "That's not one of mine!"

> [ChatGPT]: Enemy Identified: Astral Phantom – Infected Spirit Construct

Weakness: Anchor Stabilization | Emotional Resonance

"On it!"

The Battle – Code vs Phantom

Ryan jumped forward, typing mid-run.

[SpellForge: "Chain.Stabilize(Key) + Purify.Sequence(channel='Astral')"]

A chain of glowing code wrapped around the phantom. It screamed—not like a creature, but like corrupted audio warping through space.

Lucy took the opening. "Open! Gate of the Water Bearer: Aquarius!"

Aquarius launched a tidal wave, washing the construct into a wall—then vanished before she could yell at Lucy.

Ryan pressed both hands together.

[Override.Command("Debug")

→ Target: Infected Entity]

The phantom burst into shards of white and blue light, dissolving into a quiet hum.

Then silence.

Aftermath

"Thanks," Lucy said, breathing hard. "That wasn't in the job description."

"It never is," Ryan replied. "But I've got a feeling we're just getting started."

> [ChatGPT]:

Dimensional instability confirmed.

Multiple Rifts Detected across Earth Land.

New Quest:

[Patch Protocol – Track the Glitches]

Goal: Investigate dimensional rifts, seal anomalies, uncover source.

First Location: Galuna Island

Reward: XP, Spell Blueprint: "Sanity Lock", and maybe a few more near-death experiences.

Ryan grinned. "Galuna Island, huh? That's where canon gets crazy."

Lucy blinked. "What?"

"Uh—I said, sounds crazy."
