High School DxD Fanfic: Chapter 5 - The Awakening of the King
(POV: Kai)
---
The cold night of the Underworld brushed against my skin.
A low, frozen mist floated along the marble floors of the Gremory estate, whispering promises of power... and destiny.
Today was different.
Something inside me was stirring — like a sleeping beast stretching for the first time in centuries.
Rias had called it a simple training session, but even she didn't realize the storm that was about to be unleashed.
I stood alone in the Gremory training grounds, under the blood-red moon, eyes closed.
Memories of my life before flickered behind my eyelids — the betrayal, the loneliness, the helpless death.
That life was over.
This world was mine now.
I will not be weak again.
Clenching my fists, I reached deep into myself.
Into the unknown void inside my soul.
Thump... Thump... Thump.
My heartbeat quickened.
The air grew heavier.
Suddenly, my chest burned — an icy fire that felt like it was ripping apart my very being.
"Agh...!" I gasped, falling to my knees.
Cracks spread across the ground beneath me, spider-webbing outward like glass shattering under pressure.
My magic flared wildly, uncontrollable.
"Calm down!"
I heard Akeno shout from a distance, but her voice was muffled, like it was coming from underwater.
No. I couldn't stop.
I wouldn't stop.
The fire in my soul exploded outward—
—And the world froze.
A layer of crystalline frost shot across the training ground in a massive blast, covering the land in an instant.
Even the air itself froze into tiny shimmering particles.
And then...
Golden Portals opened behind me.
Hundreds of them.
Perfectly circular, glowing with divine light —
each one humming with untold power.
Weapons.
Swords, spears, axes, bows, staffs — weapons of all shapes and kinds floated inside the portals, shining with an ancient, dignified aura.
The feeling was overwhelming.
Like holding history itself in my hands.
---
"You have awakened, young king."
A voice spoke inside my mind — ancient, proud, powerful.
"You are now the Master of the Vault of Babylon, the Collector of all Might, the Keeper of Lost Epochs."
"Own it. Dominate it. Rule it."
---
My body moved on instinct.
I reached into one portal — and out came a massive silver broadsword glittering with frost, its blade radiating pure dominion.
Another portal opened — a long black spear that pulsed with cursed energy fell into my other hand.
I could feel them — not as tools, but as extensions of my will.
Gate of Babylon — no,
MY Vault of Dominion — had accepted me.
And then, the second explosion hit.
My back erupted with icy light — massive crystalline wings burst from my shoulder blades.
Dragonic scales rippled across my skin briefly before fading into shimmering tattoos.
A new symbol carved itself across my chest in pure silver — the sigil of my Sacred Gear:
> "Frost King of Dominion - Tyrannis Glaciera"
---
The ground rumbled.
Frost mist spiraled around me.
The golden portals roared.
---
Far away, from a watchtower at the estate...
Sirzechs Lucifer stood silently, arms crossed, watching the scene unfold.
Beside him, Grayfia's usual calm face cracked into one of awe.
"...He really might surpass even Ophis one day," Sirzechs muttered under his breath.
Grayfia nodded solemnly. "He was born to rule."
---
(POV Back to Kai)
I could feel it all now —
the Devil Fruit coursing through my veins,
the Sacred Gear slumbering beneath my skin,
and something deeper...
Haki.
It was faint.
Like a flickering candle in the dark.
But it was there — the will to fight, the power to dominate without touching.
It would only be a matter of time before I mastered it too.
---
A soft pair of footsteps approached me.
Rias.
She stood there, a mix of fear and awe in her crimson eyes.
"Kai..." she whispered.
"You... you're... incredible."
I smiled faintly, frost mist escaping my lips.
"No," I said.
"I'm just getting started."

Chapter Summary:
Kai awakens both the Gate of Babylon Fruit and his Frost King Sacred Gear.
Golden portals (Gate) + massive frost explosion = stunning show of power.
He instinctively draws two mythic weapons immediately.
Sirzechs and Grayfia watch, realizing his insane potential.
The faint first feeling of Haki appears (setup for future training).
Kai declares his journey has only begun!
