Seven Sins System Chapter 604. Divine Union

Seven Sins System Chapter 604. Divine Union

The magic around us shifted.

There was a ripple—an unseen pulse, like the cave itself was reacting again, only this time it wasn’t testing us.

It was recognizing us.

And then—

-Ding!

[Puriel Crystalglow de Dawnlight, Goddess of Chastity, has become your Partner.]

[Partnership Type: Divine Union]

[Bond Rank: Mythic – Irreversible]

[Bonus Effect: All Seven Sin Affinities +1000]

[Passive Bonus: +10% Resistance to Holy Magic, +5% Divine Pressure Immunity]

[Level up!]

[You are now level 267!]

The glowing thread between our wrists shimmered bright gold for a second, then shifted—warped into a double helix of light and shadow, spinning together in perfect unity before fading softly into our skin.

Our bodies trembled together.

Still locked.

Still breathing hard.

Still pressed against the wall of a forgotten cave that now felt like the center of the damn universe.

I felt her chest rise and fall against mine. Her legs, still wrapped tight around my waist, shook softly. Our sweat mixed, holy and hellish, as if it was always meant to.

But even as the aftershocks faded, something else pulled at me.

My attention flicked to the system prompt, still floating faintly in the corner of my vision.

[Partnership Type: Divine Union]

[Bond Rank: Mythic – Irreversible]

And I froze.

Not in fear. Not in regret.

No. I’d never seen this kind of notification before.

‘Divine Union.’

‘Mythic.’

‘Irreversible.’

My heart pounded hard—too hard for a devil used to being numb to everything except rage and blood.

Maybe… This wasn’t just a system acknowledgement.

Maybe it was fate laughing in my face.

I looked at her. Really looked. Her flushed cheeks, her breathless lips, her eyes still soft and dazed and warm. The Goddess of Chastity, wrapped around me. No conflict. No walls. Just us.

I was a devil.

She was a divine.

Enemies by nature.

And now… this.

Am I fuckup as the prince of the underworld?

Or…

Is this going to be something else?

Something I can’t define.

Something bigger.

My thoughts scattered when her forehead touched mine.

Still holding me.

Still gripping my horns like they belonged to her now—like she’d earned them, claimed them, knew exactly what they meant and didn’t give a damn. And I didn’t stop her.

“I love you,” she whispered again. No hesitation this time. Just truth.

And I smiled—weak, breathless, full of everything I never thought I’d have.

“Yeah,” I murmured, eyes closing as I leaned into her touch. “I know.”

And for once…

That didn’t sound like arrogance.

It sounded like the truth. The kind that settled deep in my chest and wrapped around my ribs like a chain made of warmth instead of weight.

She released my horns slowly, her fingers trailing down their length like she wasn’t quite ready to let go. And even when her hand fell away, I could still feel it. That touch. That permission. That quiet claim.

But instead of pulling back, she leaned forward again—resting her head gently against my core.

Her cheek pressed to the cracked, glowing surface right at the center of my chest. That fragile spot that pulsed with the essence of everything I was. Wrath. Memory. Power. Pain.

She listened.

Just listened.

As if the rhythm of my demonic core was a melody meant for her ears alone.

“You are listening to it as if it’s heavenly,” I murmured, breath uneven, voice still raw from everything we’d just done. “It’s corrupted mana held together by spite and fury.”

She didn’t move.

Didn’t argue.

She just whispered back, “It’s beautiful.”

And that? That messed me up more than I was willing to admit.

I wrapped my arms around her tightly, holding her against me, not wanting to move—even though my body had other plans.

Because yeah…

I could still feel it.

My erection.

Still hard. Still twitching deep inside her like it refused to accept this was over.

‘Dammit…’ I cursed internally, head tilting back to rest against the wall, horns brushing the cold stone. ‘I feel like Asmo already.’

That thought alone made me cringe.

I wasn’t like him. Not that kind of demon. I didn’t take without restraint. I didn’t lose control. And I sure as hell didn’t let lust dictate me like some feral beast.

Except… right now?

Right now, I wasn’t so sure.

Because I could still feel her heat wrapped around me. Still feel how tight, how perfect she was. My core was still burning, the magic in the air still humming, and every instinct I had screamed at me that this wasn’t enough.

Not yet.

Not nearly enough.

I remembered what I told her that day—back in the mortal world, when we crossed paths again and this cursed thread between us reactivated.

“I want to rape you and bathe you in my cum, so no low demon even thinks about touching you.”

It was crass. Brutal. Wrong.

But also… honest.

Because I was the most possessive bastard the underworld had ever known. I didn’t share. I didn’t lend. And once someone became mine—that was it.

No second chances.

No escape.

And Puriel?

She was mine now.

Fully.

And the idea of stopping here—after everything? After she gave herself to me, trusted me, told me she loved me?

No.

No way.

I wanted more.

More than her body.

I wanted to claim her so thoroughly that every divine being above and every cursed demon below would know she was untouchable—marked in ways that even gods couldn’t undo.

I wanted to see her carry my child.

Our child.

That thought hit harder than any climax. It settled in my gut like a storm waiting to explode.

And I didn’t even hesitate.

My hands slid under her thighs, lifting her just slightly against the wall again. Her head rose from my core, eyes fluttering open as she looked at me—still flushed, still glowing faintly with divine aftermath.

“Azrael…?”

Her voice was soft, hoarse, but there was no fear in it.

Only knowing.

And maybe even anticipation.

I didn’t answer.

Not with words.
