Gremory Mansion – Private Training Grounds

Naruto stood alone in the expansive training grounds behind the Gremory mansion, his breath slow and steady. The sky above was clear, but there was a pressure in the air, an unnatural stillness.

His mind was a storm.

The revelations in the Leviathan Archives had left him shaken—but not broken. If anything, he felt stronger than ever.

"The Catalyst of Chaos…"

It wasn't just a title. It was something fundamental to his very being. A power so vast that the gods and devils alike erased it from existence.

But now?

He was back.

And he wasn't about to let the past dictate his future.

He extended his hand, summoning his Demonic Compression Blade, but instead of the usual black-red energy, the sword flickered between void-like darkness and something else—something ethereal.

"My power is changing."

His system interface glitched, struggling to process the unknown energy surging through him.

[System Warning!]

Anomaly Detected: Unstable Catalyst Energy Manifesting.

• New Ability Unlocked: "Aetheric Destruction"

• Status: Unstable. Immediate Training Required.

Naruto smirked. "Looks like we're finally getting somewhere."

Before he could push further, a portal of golden energy shimmered to life behind him.

A new voice spoke.

"You always find new ways to make trouble, don't you?"

Naruto turned, eyes narrowing as a tall man with raven-black wings stepped through.

Azazel.

The Governor of the Fallen Angels, ex-leader of Grigori, and one of the few beings who knew more about the supernatural world than anyone else.

And right now? He was smirking like he knew something Naruto didn't.

Meeting With Azazel

Naruto crossed his arms. "Let me guess—you're here to tell me not to poke the ancient cosmic bear?"

Azazel chuckled. "Oh, hell no. I'm here because you're doing exactly what I hoped you'd do—breaking the rules of reality."

Rias and Akeno arrived just in time to hear that.

"Azazel?" Rias frowned. "What are you doing here?"

Azazel ignored her, his golden eyes locked onto Naruto. "I've been watching your progress, kid. And after that little revelation in the archives, I figured it's time we had a chat."

Naruto raised an eyebrow. "About what?"

Azazel's smirk faded slightly. "About why the gods feared you enough to erase you."

Silence.

Akeno's eyes widened. "You knew about the Great Fracture?"

Azazel nodded. "I didn't just know about it—I was alive when it happened."

Naruto's mind reeled. "Wait, what?"

Azazel sat on a nearby boulder, stretching lazily. "Long before the current factions existed—before the Devils, Angels, and Fallen split apart—there was a force even older than the gods themselves. It wasn't good. It wasn't evil. It was… chaos."

Naruto felt a chill run down his spine.

Azazel pointed at him. "And you, my friend? You were the embodiment of that force."

[System Notification]

New Lore Unlocked: "The First Catalyst"

• The Catalyst of Chaos wasn't just a warrior—it was a cosmic force given form.

• Its existence shattered balance, forcing all pantheons to unite against it.

• Naruto's soul is a reborn fragment of that lost power.

Rias's voice was barely above a whisper. "So… Naruto isn't just reincarnated. He's something beyond reincarnation."

Azazel nodded. "Bingo. And that's why the Night Reaper is after you."

Naruto clenched his fists. "Because he was one of the ones who erased me."

Azazel's eyes gleamed. "Exactly."

Silence hung in the air before Naruto grinned. "Then I guess it's time I start getting my power back."

Training the Unstable Power

Azazel stood, cracking his knuckles. "You're on the right track, but raw power alone won't cut it. If you're serious about unlocking the Catalyst's true potential, you need to train in a place that can handle it."

Rias narrowed her eyes. "And where exactly would that be?"

Azazel's smirk turned dangerous. "The Abyssal Rift."

Naruto tilted his head. "Never heard of it."

Azazel chuckled. "That's because no sane person goes there. It's a fractured realm—a place that exists between reality and nonexistence."

Akeno frowned. "And you think that's a good place for Naruto to train?"

Azazel shrugged. "If he wants to access the power of chaos, he needs to step into the void from which it came."

Naruto grinned. "Sounds like fun."

New Quest: "Journey into the Abyssal Rift"

• Objective: Enter the Abyssal Rift and survive its trials.

• Bonus Objective: Unlock a sealed fragment of your past power.

• Rewards: 8,000 XP, Evolution of Destruction Magic (Tier 3), ??? (Unknown Power).

Rias sighed. "This is insane."

Naruto turned to her, his grin softening. "That's kinda my thing."

A flicker of worry crossed her eyes, but she nodded. "Then I'm going with you."

Naruto blinked. "What?"

Rias crossed her arms. "If this is who you are—if this is the path you have to walk—then I won't let you walk it alone."

Akeno stepped forward, her usual playful smirk returning. "Ara~ If Rias is going, then I can't just stay behind."

Kiba chuckled. "Besides, someone has to keep you from getting yourself killed."

Koneko just nodded. "Tch. If you die, I'll kill you."

Naruto stared at them for a moment before grinning. "Guess we've got a field trip."

Azazel laughed. "Well then, let's not waste any time. The Abyssal Rift isn't going to wait for you."

With a flick of his wrist, he opened a swirling portal of violet-black energy.

Naruto stepped forward, the power within him thrumming in response.

"Time to meet my past."

And with that, he stepped into the unknown.
