My Dark Devil System

The rain had quieted into a gentle drizzle, but Kael's mind was a thunderstorm. Each drop against the stonework of the ruined city sounded like a ticking clock—every second slipping toward the day his soul would be claimed.

He sat across from the boy, Tenn, in the collapsed cellar. The crimson lantern flickered between them, casting shadows that didn't move quite right.

Tenn hugged his knees, glancing every few seconds at the shard he'd stolen—the Shard of the Worldforge—now sealed inside a black veil Kael conjured using the System.

Kael watched him quietly, reading more than the boy let on.

System Alert:

[Sin Detection – Failed]

Reason: Subject's soul resonance is… incomplete.

Kael's Thoughts (Internal Monologue)

No sin signature. No moral echo. He's like a hollow vessel… or a sealed one.

Either way, he's not normal. But that makes him useful. Maybe even necessary.

Kael stood, his cloak sweeping the dust off the stone as he walked to a corner and traced a sigil into the floor.

The symbol pulsed with red and gold—a mix of Wrath and Greed.

[Vault of Gluttony: Accessed]

Stored item retrieved: Mask of Echoes

He tossed the relic to Tenn.

"Wear this," Kael said. "It will hide your presence. No more wandering priests sniffing you out like bloodhounds."

Tenn caught it but didn't put it on. "Why are you helping me? You don't look like the saving kind."

Kael smirked. "I'm not. I'm the burning kind."

Scene Transition – Echo of the Forgotten Chapel

Kael and Tenn slipped through the underground ruins, eventually reaching a broken church on the city's edge. The ceiling was gone, replaced by a tangle of overgrown vines and shattered glass.

This was once Chapel Lucis—a training ground for sacred exorcists… and a forgotten site of Kael's early days.

He clenched his fists as memories flooded in.

[Memory Triggered – Passive Gluttony Skill: Digest Memory – Local Anchor Recognized]

Flashback Sequence – Age 10

Kael knelt in prayer. Bleeding palms. Broken ribs. The priest behind him held a whip of holy light.

"You failed the Rite of Chains," the priest hissed. "You let doubt crawl into your soul. Doubt is filth."

"I only wanted to understand why…" young Kael whispered.

The whip came down again.

"Wanting is a sin."

Back to Present

Kael opened his eyes. They glowed dim crimson.

[Fury Meter: 34% – Memory Trauma Boost]

[System Whisper – Lucivar Interjection]:

You keep digging into the past like it owes you closure. But you'll only find ruin. Or worse… roots.

Kael ignored him.

He activated [Sin Detection] again—and this time, the chapel floor lit up.

A hidden glyph.

A sigil of binding. Arcane. Ancient.

Beneath this chapel… Project Heirlock's Prototype Vault.

New System Quest Unlocked!

Quest: Unseal the Vault of Heirlock

Objective: Break the triple-bind seals placed on the chapel foundations.

Danger Level: Deadly!!! Proceed with Caution!

Reward: Forbidden Evolution Tree Fragment, +25 SP, Potential Devil Contract (High-Value Target)

Kael turned to Tenn. "There's something under us. Something they buried. And I'm going to dig it up."

Tenn nodded but his eyes darted toward the glyphs. "What if it's dangerous?"

Kael cracked his knuckles. Flames danced on his fingertips.

"That's what makes it worth it."

Scene Transition – Seal One: The Grave of Names

The first seal wasn't locked by magic, but by memory.

Dozens of names carved into black stone. Faded. Almost unreadable.

One stood out. "Kael V." Crossed out.

System Interjection:

To break this seal, you must reclaim what was denied: Your name.

[PRIDE Tree Skill – Overlord's Stance: Activated]

Kael stepped forward, eyes burning.

His voice echoed in the tomb:

"I was never yours to erase."

With a roar, he plunged his hand into the stone, shattering it.

[Seal One Broken]

[PRIDE +2]

[SP Gained: +10]

Seal Two: The Trial of Sin

Three stone guardians rose from coffins—statues animated by divine wrath. Each represented a sin Kael had embraced: Wrath, Greed, and Envy.

To break the seal, he had to survive all three forms of himself.

[WRATH: Wrathbone Guardian Activated]

[ENVY: Shadowclone Protocol Initiated]

[GREED: Phantom Leech Deployed]

It was chaos. Fire met illusion. Kael dodged a mimic of his own [Hellfire Pulse], only to be struck by [Golden Fangs] from the phantom.

But Kael had evolved.

[Seething Core Activated]

[Blazing Ruin Fist – Empowered]

He punched through his WRATH clone, then lured the ENVY shadow into a mirrored wall, where it destroyed itself in confusion.

Finally, Kael unleashed [Devour Essence] on his GREED mimic.

All three shattered.

[Seal Two Broken]

[SP Gained: +15]

[Greed Tree: Skill Fragment Unlocked – "Fortune Hook"]

[Sin Alignment: Tilted Further into Damnation]

Seal Three: The Choice

The final seal was not a fight.

It was a mirror.

Kael saw himself—not as he was, but as he could have been. Pure. Devoted. Forgiven.

The image spoke:

"Walk away. Deny the pact. You still have time. Redemption awaits."

Tenn looked at Kael. "Are you gonna listen?"

Kael's hand clenched into a fist.

"I didn't survive to be someone else's salvation. I survived to become retribution."

He spat on the mirror.

It cracked. Then shattered.

[Seal Three Broken]
