Devil Slave (Satan system)

...From beneath a mountain of shattered stone and burning rock, a low chuckle echoed, deep and mocking.

Uriel rose, golden blood still dripping from the corner of his mouth, wings torn but his poise untouched.

The rubble crumbled around him like dust, and he dusted his palm across his chest where one of Enel's slashes had nearly cleaved his armor.

"Impressive," Uriel said, voice smooth, almost amused. "Very impressive."

He floated higher, locking eyes with Enel whose breathing was calm but tense, his sword still pointed forward, unwavering.

Uriel smirked.

"You can learn a lot about a person from the way he fights… And in every blow you landed, I could feel it—you are scarred, child. Deeply."

Enel's expression darkened, jaw tightening.

His grip on the hilt shifted slightly.

"I'm not scarred," he said coldly.

Uriel tilted his head, as if studying him.

"Then why didn't you end it?" he asked softly. "You had me. One more strike—just one—and I wouldn't be standing."

A tense silence settled in the cosmos.

Uriel's eyes glowed with a dangerous understanding.

"I'll tell you why. Because your goal isn't my end."

His voice sharpened.

"You didn't come to win. You came to preserve. If you kill me here—now—you alter your future. You erase it. Everything you know, everyone you've met, every loss you've endured… would be unwritten."

Enel growled, eyes narrowing.

He knew it.

Damn it, he knew it. This was the paradox effect taking place.

Enel flashed back to knowledge of one such instance of a paradox.

'If a child who hated his grandfather built a time machine and went back in time, to the point of hid birth to kill him, would he then be born and build the time machine?'

Paradoxes we're too dangerous to mess around with.

It coikd even collapse the cosmos.

Uriel smiled wider, his voice now taunting.

"You were always cautious. But now I see the full picture. You never aimed to kill me… because you couldn't afford to."

He took a step forward in midair, golden light simmering around him.

"But that's not the only reason, is it? You've also been holding back."

Enel's eyes twitched. His stance shifted. He said nothing.

Uriel's grin widened to something almost predatory.

"That's right. You've been going easy on me. And still—you were winning. What a surprise. To know that we were both holding back."

The truth bit like a blade. And Enel cursed under his breath.

"Tch—Damn you, Uriel."

Without another word, Enel flicked his sword aside, the magic flaring and vanishing into stardust. He shot forward—a blur of cosmic force—grabbed Allison by the waist, and with a burst of energy that cracked space behind him, took off into the distance, streaking across the heavens like a meteor fleeing death.

From the rock bed, Uriel blinked.

Then he laughed.

Loud, amused, and unstoppable.

"Not bad," he said, lifting into the sky. "A wise choice… you could even tell that i have called for reenforcements. You are cery wise.."

His eyes glinted with something darker.

"But not against me."

BOOM!

Uriel vanished, trailing starlight, launching into the sky after them.

He tore through the heavens with terrifying speed, a golden blur weaving past floating meteors, shattered asteroids, and fragmented debris drifting in the starlit expanse.

Each rock he passed vibrated under his divine presence. He was a predator unleashed, unrelenting.

"You won't escape me," he whispered into the void.

But what he didn't know… was that one of those very rocks—massive, cracked, and hovering in a gravitational lull—hid his prey.

Tucked tightly behind its jagged side, Enel, Allison, and a third figure crouched in tense silence.

A young woman, no older than nineteen by human appearance, stood calmly with her hand raised in a gesture of quiet. Her eyes flickered like galaxies contained within small glass orbs.

Uriel streaked by with fury in his wake—oblivious.

Only once his light was gone did Enel exhale slowly.

He turned to the strange girl beside them.

His eyes narrowed. "You… you're an Entity."

The girl nodded softly, brushing a lock of glittering white-blue hair behind her ear.

"Yes. Now shhh. The hologram I cast is convincing, but it won't fool a Cherubim forever."

Her voice was calm and melodic, yet every word seemed to carry immense weight.

Then she waved a delicate hand, and a swirling portal shimmered open beside her.

"Come. Quickly. Before he doubles back."

Allison held back. Her eyes, narrowed in suspicion, never left the strange girl.

She heard what Enel had said. This was an Entity. And earth in their own time had history with entities. It was not good history.

In fact, it was very terrible history.

"I don't trust this... Entity. Especially Not in this time."

But Enel stepped forward without hesitation.

"I know. It's strange… but I do trust her."

Allison looked at him sharply. "How? Why?"

Enel's eyes glowed faintly with memory.

"Since we came to this era, I've been hearing whispers. A voice… her voice. She was the one who told me to take you and run. The direction, the timing—everything. It was all her. And she kept her word."

The Entity smiled faintly—almost shyly—as though unused to praise.

She waved again, and the portal solidified like liquid glass.

Without further delay, she stepped through it.

Enel turned to Allison, who still looked hesitant—but followed.

Together, they passed through the shimmering veil… and emerged in a realm unlike any they had ever seen.

It was a world painted in radiant hues—a bridge of light stretched across the stars, shimmering with flowing rivers of colors that danced through the air like ribbons. Soft music sang from the wind itself, and flowers bloomed in midair, their petals whispering peace with each gentle flutter.

The entire place felt alive, as though the very fabric of its creation pulsed with joy, peace, and emotion. One step in it, and Enel's burdens felt lighter. Even Allison's tension eased, if only slightly.

The strange girl turned to them, her glow now far more pronounced.

She was ethereal—as if she was more presence than flesh. Her hair rippled like a veil of stars. Her skin was pearlescent, kissed by every color of the bridge they stood on. She did not glow… she radiated, and the world around her responded with joy. When she smiled, even the mist glittered.

But as she turned to speak, she tripped on her own foot, gasped, and caught herself on a floating petal.

"Oops! I, um… meant to do that," she said, flushing.

Enel blinked, then chuckled softly.

"You are… her, aren't you?"

Allison turned, confused. "Her? Who is her?"

The girl bowed her head politely, placing a hand over her chest.

"Yes, I am. I am known as the Entity. The embodiment of the strongest force in creation."

She raised her head, eyes twinkling with kindness.

"I am Love."

Allison's eyes flew open wide in realization—and for a moment, she looked like she might fall to her knees. Her breath hitched.

"Wait… if you're Love—then this place… this can't be…"

Enel turned, a smile tugging at his lips as he stared into the ever-stretching prismatic beauty around them.

"The Rainbow Bridge," he said, finishing her thought.
