Transmigrated into Fairy Tail with a ChatGPT

Chapter 4: Chapter 4 – Shadow Codes on Galuna



The Mission:

Investigate a cursed island where demons roam, villagers mutate at night, and forbidden magic lingers.

The Party:

Natsu, Lucy, Happy… and now Ryan.

The small sailboat rocked on the waves beneath a crescent moon.

"So you snuck onto the mission?" Lucy scowled at Natsu, arms crossed.

"We were gonna go anyway!" he grinned. "If you didn't come, I was gonna drag you."

Happy chimed in. "Aye! And Ryan too!"

Ryan, clinging to the edge of the boat with a pale face, muttered, "I hate boats. I hate water. I hate cursed islands. I hate all of this."

Would you like a quick tutorial on debuff cleansing?

"Please… yes."

Arrival – Galuna Island

By the time they reached the island, Ryan's spell had kicked in and he no longer felt like vomiting his soul into the ocean. The group stepped onto shore, the air thick with unease.

Dark trees loomed. The stars were dimmer here. And something buzzed in Ryan's head—not physical, not magical, but... syntactical.

Environmental Warning: Code Contamination Detected

Location: Ruins of the Moon Temple

Status: Corrupted Memory Fragments Present

Advise: Proceed with caution. Reality is unstable in this zone.

"Wait—did you say memory fragments?" Ryan asked aloud.

"What memory?" Natsu asked.

"…Nothing."

The Village and the Curse

As in the original story, the team encountered the villagers—kind-hearted people with demonic transformations under the moonlight.

Lucy clutched her keys tighter. "They're cursed... just like in the story."

But Ryan wasn't listening. His eyes were locked on a strange shimmer above one of the huts—floating lines of transparent text, like ghost code, barely visible unless you looked directly at them.

He blinked. "Is that… a memory file?"

Fragment Identified: [ShadowDump.v1]

Playback?

He nodded.

The world around him shifted.

Corrupted Memory – Playback

Ryan stood alone in an illusion.

The village was burning. Screaming. Not humans—but demons.

A shadowed figure stood over the temple. Not Deliora. Not Lyon.

Himself.

"Unauthorized user detected," said a voice behind him. "Scriptweaver anomaly. Purge initiated."

Ryan turned—something faceless and made of fragmented code lunged at him—

And then he was back in the real world, gasping.

Team Tension

"You okay?" Lucy asked. "You spaced out."

"I… I saw something," Ryan said. "Something bad."

"You sure you're not cursed too?" Natsu asked.

> [ChatGPT]: Fragment confirmed.

You witnessed a false future. A potential outcome overwritten.

Warning: Someone—or something—is tampering with the timeline.

Target: You.

"I think…" Ryan whispered, "someone's rewriting reality."

Ruins of the Moon Temple

They reached the temple just as Lyon and his followers prepared to unseal Deliora.

Ryan's eyes widened. "This is it. The turning point."

As Natsu charged forward to confront Lyon, something in the ruins twitched—not the ice, not the demon—

The Code.

> [ChatGPT]:

WARNING: System Intrusion

Entity Signature: "Voidwalker"

Accessing Ruins Core...

Countermeasure Available: Deploy Spellforge Lockdown?

Ryan didn't hesitate.

[SpellForge: Lock('Codebase.Root', barrier=True, duration=60s)]

A glowing hex-lock web spread through the temple, freezing the code pulses—but just for a moment.

From behind the seal… a shape began to push through.

Not Deliora. Not the original demon.

A creature made of void, half-data, half-flesh. Its form flickered between demon and human—between Lyon's face… and Ryan's.

The real Deliora was still frozen.

This was something else.

New Threat Detected

Name: Shadow Patch

Type: Memory Clone / Script Parasite

This isn't just magic.

It's a test.

Of you.
