Seven Sins System Chapter 854. Monsters Under The School

A pressure rolled over us from below. Heavy. Thick. Wrong. Not visible. Not audible. But every instinct in my body recognized it.

Something was there.

Not physically present.

But the aura rose like a giant opening its eyes beneath the building.

My system flared.

[Warning]

[Massive Entity Signature Detected]

[Classification: Unknown Hybrid Composition]

[Threat Scale: Large-Class / Concealed Manifestation]

[Physical Body: Not Detected]

[Presence Projection: Active]

[Possible Anchor: Living Host Network]

[Priority Alert: Children Detected Within Threat Radius]

Mamon’s tablet buzzed violently.

His face changed.

Puriel and Lumira felt it too without any system. Their wings spread slightly, light pulsing. Luci’s mask wrinkled as his expression twisted beneath it.

That aura…

It was like something gigantic stood before us.

A creature.

A huge one.

Not seen.

Not shaped.

But felt.

A hybrid. Artificial. Layered. Something stitched together from residue, souls, maybe children’s fear, maybe living mana, maybe something worse. It towered in the invisible space above that cheerful elementary school like a monster wearing the building as skin.

And there was nothing there.

No visible enemy.

Just pressure.

A grin pulled across my face before I could stop it.

Adrenaline rushed through me, hot and violent.

The thing that made Wrath wake up properly.

Not investigation.

A threat.

A big one.

My fingers flexed. My tentacles stirred behind me, hungry. “Shit…” I muttered, smiling wider. “Let me destroy them all.”

Puriel immediately looked at me. “No.”

That single word cut through my rising aura like a blade.

I looked at her.

She didn’t flinch. “They’re using the children as their shield.”

My smile thinned.

I knew.

That was why my hands itched worse.

Luci slowly reached up and grabbed the edge of his skincare mask. For one dramatic second, he peeled it from his face. Then he crushed it in his hand.

Violet flame swallowed the wet sheet instantly, burning it into elegant ash.

His real face appeared again. Perfect, furious, beautiful in the kind of way that made mortals make bad choices and devils start wars. “They…” His voice dropped. “Are challenging me.”

His smile split open.

Pride offended at a cosmic level. “They hid behind children.” His wings opened wider. “They dared build ugliness under education.” His eyes glowed. “They think I will hesitate.”

I stared at him. “Will you?”

He looked at me.

We both grinned.

Mamon moved between us immediately. “Hey.”

No response.

“Calm down, you two.”

Still no response.

He sighed sharply and snapped his fingers. Golden coin chains appeared in the air between us, not binding, just enough to block our forward movement.

“First,” he said, voice cold, “we get in peacefully.”

I slowly turned my head toward him. “Peacefully?” I hated that word.

Luci looked insulted. “Infiltration? That is disgusting.”

Mamon adjusted his glasses. “Everything today is disgusting. Adapt.”

Lumira nodded immediately. “Mamon is right.”

All three devils looked at her.

She looked deeply pained by the sentence but did not retract it.

“We need to know where the children are,” she continued. “If there is a hidden clinic below or inside the school, we cannot attack from above.”

Puriel’s gaze stayed on the building. “I can sense fear. But it’s muffled. Something is dampening emotions inside.”

Mamon’s tablet projected a schematic, not complete, more like a financial crime map pretending to be architecture.

“School above. Underground extension below. The residue marker is under the east wing. There are energy dampeners along the walls.”

I stared at the school.

Children moved in the courtyard below.

Small figures in uniforms.

Laughing.

Running.

Playing.

My anger changed shape.

Sharper.

The invisible giant aura pressed down again, as if daring us.

My jaw tightened. “I wonder if they know about our peace agreement and are using it against us. As long as they hide behind mortals, we can’t kill them recklessly.”

Mamon nodded. “Probably.”

Lumira flew slightly lower, eyes glowing softly. “I can create a kindness veil to calm the children if panic starts.”

Puriel nodded. “I’ll separate civilians from hostile energy. But I need a few seconds once we’re inside.”

Mamon looked at both angels. “If it turns worse…”

He paused, then his eyes shifted to Puriel and Lumira. “You know what to do.”

Lumira’s face became serious. “Evacuate the kids.”

Puriel nodded once. “And after that?”

Mamon looked at the school. His voice went flat. “Then we, the devils, will destroy the building.”

Luci smiled.

I smiled.

Puriel didn’t.

Puriel looked at both of us like she could already see the future headline.

“ELEMENTARY SCHOOL EXPLODES AFTER DEMONIC INCIDENT.”

We moved.

Not flying down like dramatic celestial meteors because apparently we were trying to avoid panic. So we teleported. One moment we hovered above the school like a group of extremely suspicious birds, and the next, shadow and gold folded around us.

The sky vanished.

The rooftop appeared beneath our feet.

Flat concrete.

Air-conditioning units.

A water tank.

A faded painted line where some mortal maintenance worker probably once smoked during lunch and contemplated quitting.

Below us, children laughed in the yard.

A school bell rang.

The white van continued toward the side entrance.

I crouched near the roof edge and watched.

“Angels first,” Mamon murmured.

Puriel and Lumira nodded.

They didn’t hide what they were completely.They descended from the roof in softened angelic form, wings visible but veiled, faces covered with pale cloth and golden light. Not masks like ours. More like gentle obscuration. Holy anonymity.

Smart.

Because children liked angels.

Not in the complicated adult mortal way with religion, desire, fear, worship, media, and annoying questions.

Children liked angels because angels looked safe.

Kind.

Bright.

Like someone who would protect them from monsters under the bed.

And today?

There really were monsters under the school.

Lumira landed first near the yard, light spreading softly from her feet. The children froze for half a second.

Then several gasped.

One small girl pointed. “Angel…”

The teachers panicked faster than the kids.

Adults always ruined wonder with liability concerns.

Puriel raised one hand gently, and the air calmed. Not domination. Not control. Just emotional pressure turning fear into trust.
