Seven Sins System Chapter 778. Babysitting Demonic Nobility

Luci lifted his head slowly, staring at him like he might throw a decorative lamp.

I pinched the bridge of my nose.

Yes.

This semester was absolutely going to kill me.

I shut Luci’s door gently behind me, letting the muffled sound of his ongoing existential crisis fade into the hallway.

I caught fragments as I walked away. Something about “pressed wood betrayal” and “cotton tyranny.”

Algan’s door clicked shut more quietly. He at least had the decency to suffer in silence. Or inventory his room like it was a bunker inspection. Probably both.

Back in my room, the quiet felt earned.

I peeled my coat off first, draping it over the chair like muscle memory from a hundred other nights that ended with too much blood or too many decisions. The desk lamp hummed softly when I turned it on, casting a warm circle of light across paperwork I had already memorized.

I sat.

For half a second, it was peaceful.

Then my system flared.

Not a gentle ping. Not a warning chime. A full body awareness spike that slid down my spine like ice water.

[High intensified angelic power detected.]

[Source identified: Goddess of Kindness, Lumira.]

I leaned back in the chair and stared at the ceiling.

“Ah,” I murmured. “She came.”

Kindness herself. Lumira. That explained the sensation. Angelic power always felt sharp, but hers wasn’t blinding or oppressive. It was… warm. Heavy in a different way. Like sunlight filtered through stained glass. Beautiful. Distracting. Dangerous in its own way.

Which meant Puriel was involved.

Kindness didn’t operate solo. Not anymore. She would be Puriel’s teammate in this investigation, whether I liked it or not. That also meant she was staying here. On campus. Probably temporarily. Probably already making mortals feel inexplicably safe just by existing.

I frowned slightly.

I hadn’t heard Red mention accommodations for a goddess.

“Fine,” I muttered. “Puriel’s dorm it is.”

I had already warned Luci and Algan about this. Luci would absolutely make this worse. Algan would stand very still and pretend not to understand why angels made him uncomfortable. Same as always.

I stood and headed to the bathroom.

The shower water was hot enough to steam the mirror, washing the lingering scent of infernal ash and hallway stress off my skin. I let it run over my shoulders longer than necessary, hands braced against the tile while my mind sorted priorities.

Mission first.

Blending second.

Babysitting demonic nobility unfortunately constant.

I dressed in clean clothes afterward. Simple. Dark shirt. Slacks. No coat. No aura. Just Dr. Allen again. The reflection in the mirror looked… normal. Too normal. Sometimes that unsettled me more than horns ever had.

Back at the desk, I opened my laptop.

The familiar glow grounded me. Case files loaded one by one, filtered by keywords I had been tracking since before this semester even began. But now… I added more keywords. Cult activity. Summoning residue. Hybrid instability. The usual mess left behind when mortals played with forces they didn’t understand and then acted surprised when consequences showed up wearing teeth.

Half angel and half demon constructs were unstable by nature. Most of them burned out. Some escaped containment. The dangerous ones learned to hide.

I skimmed reports quickly.

A “possessed influencer” in a coastal city that turned out to be smoke machines and staged hysteria.

A supposed “fallen angel sighting” that ended up being a drone with LEDs and a bad soundtrack.

Bullshit.

So much bullshit.

Mortals loved pretending they were special. Loved borrowing divine language to justify their own hunger for attention. It made real cases harder to spot. Louder lies drowned out quiet truths.

Then there was the new permission from my father.

I scrolled to that file, jaw tightening slightly.

Summons.

We were allowed to answer them now. Limited. Conditional. But allowed. This time, we didn’t just appear and solve the problem. We observed. We recorded. We traced who called us and why.

And if those people were connected to the ones who had collected infernal remains…

I closed my eyes briefly.

We would pull them apart until they confessed. Slowly. Methodically. No glamour. No mercy.

I found one flagged report that hadn’t been fully cleared.

A demon appearance. Alleyway. Specific location. Patterned around intoxicated targets. Late hours. Witness accounts inconsistent but overlapping enough to be annoying.

I snorted quietly.

“Sounds like another bullshit case.”

But my cursor hovered.

Bullshit sometimes hid real things underneath.

I marked it.

“Hmm,” I said softly. “We’ll see.”

For now, though, the campus demanded attention.

I closed the laptop and leaned back, letting the chair creak quietly beneath me. My gaze drifted toward the window. Night had settled fully now. Campus lights dotted the grounds like fireflies trapped in glass. Students moved in small clusters, laughter echoing faintly up from the paths.

Then I noticed the rooftop.

Female mentor building. Rooftop. One figure standing near the edge.

White.

Not glowing. Not blazing like before. Her wings weren’t fully manifested. Just the faint suggestion of light pressed close to her back. Controlled. Intentional.

Puriel.

She wasn’t glaring this time.

No judgment. No challenge.

Just presence.

An invitation.

I sighed through my nose.

“Of course.”

I stood, crossed the room, and vanished.

The teleport was tight and precise. No ripple. No spectacle. I reappeared a few steps away from her on the rooftop, boots landing soundlessly against concrete still warm from the day’s sun.

The air up here smelled cleaner. Night breeze. Ozone. Something faintly floral drifting from the gardens below.

Puriel turned toward me slowly.

Her expression was calmer than the last time we spoke. Guarded. Tired. Honest in a way angels rarely allowed themselves to be.

The wind brushed across the rooftop, cool and steady, carrying the scent of night flowers from the gardens below. Her hair shifted with it, catching moonlight in soft strands. No blaze of judgment. No divine pressure. Just her, standing there like she had chosen this moment carefully.

“I see Kindness has arrived,” I said.

She nodded once. “Yes.”

A pause.

“So have Luci and your lieutenant.”
