Seven Sins System Chapter 776. Economically Tragic

He studied her for a moment, then hummed thoughtfully.

“I still think he looks ridiculous,” Luci said.

I adjusted my collar calmly. “You will be wearing slacks and sweaters by tomorrow.”

His expression froze in horror.

“…I would rather fight Heaven again.”

“You will be teaching mortal teenagers,” I reminded him.

“That is arguably worse.”

Red cleared her throat sharply.

“We are not debating wardrobe trauma,” she said. “We are discussing infiltration protocol.”

Luci exhaled dramatically. “Fine. What else?”

“Mortal habits,” Penelope chimed in cheerfully. “You eat cafeteria food. You use technology without breaking it. You socialize.”

“I do socialize,” Luci said.

“You flirt and insult people simultaneously,” I corrected.

“That is advanced socialization.”

Algan raised his hand slightly.

“Question,” he said.

We all looked at him.

“If a student challenges me to physical confrontation… what is acceptable response level?”

“De-escalation,” Red said immediately.

“What if they persist?”

“De-escalation with authority.”

“What if they attempt lethal force?”

Katrina sighed. “They are mortal students, Lieutenant.”

“…Understood.”

Luci leaned closer to him and whispered loudly, “You are going to hate this place.”

I rubbed my temples.

“Welcome to the mortal realm,” I said.

Red clapped her hands once, crisp and efficient, like she had just concluded a corporate onboarding meeting for two extremely dangerous demonic dignitaries and one emotionally attached war lieutenant.

“Great,” she said brightly. “So…”

She reached into the drawer of the desk and pulled out two sleek metallic keycards. They shimmered faintly under the fluorescent office lighting, each embossed with academy security sigils disguised as ordinary access chips.

She handed one to Luci and one to Algan.

“Dr. Allen will take you to your room,” she said smoothly.

Luci stared at the card in his hand, turning it over like it might explode or insult his lineage. Then he looked up.

“Who is Dr. Allen?”

I raised my hand lazily.

“Me.”

He blinked.

“…I beg your pardon.”

“That is my name here,” I said. “In the mortal realm.”

He physically recoiled.

Not subtly.

Full recoil. Shoulders pulling back. Nose wrinkling. Eyes narrowing like he had just smelled expired mortal dairy.

“Ew…” he muttered.

Penelope coughed to hide laughter. Katrina didn’t even try to hide her smirk.

Luci looked me up and down, taking in the coat, the slacks, the very deliberately neutral human aura I was wearing like a perfectly pressed disguise.

“Just… Ew…” he repeated. “I feel like I don’t know you, El.”

“Shut up,” I said flatly.

I pointed at him.

“You also have a new name. Luci is fine. Or Professor Luci.”

He froze.

“Professor?” he repeated slowly, like he was tasting poison.

“I am a lord,” he corrected. “A sin lord.”

I gave him a flat stare that could have peeled paint.

He held my gaze for three seconds.

Four.

Five.

He exhaled dramatically like someone surrendering a royal decree.

“…Fine.”

Penelope stepped forward then, tapping Luci’s keycard lightly with her nail.

“I already placed some clothes, uniform options, and normal necessities in your rooms,” she said cheerfully. “Nothing fancy.”

Luci’s eye twitched.

“Some food, a basic phone, and your class schedules. There are also digital maps of the academy on the devices,” she added.

Algan nodded like she had just issued combat logistics.

“Understood.”

Katrina lifted one finger.

“Oh, right. One more thing.”

They both looked at her.

“No teleportation in public places.”

Luci nodded immediately. “Right. Of course.”

He paused.

“…Now, let us proceed to this pathetic room.”

I sighed.

“You are both still in demonic form.”

They looked down at themselves instinctively.

“Be human,” I said.

Luci groaned. “Fine. Human. Dammit!”

Both of them shimmered.

The transformation wasn’t flashy. Just a controlled dimensional compression of presence and anatomy.

Algan shrank first. His shoulders lost a few inches of war-bred breadth. His height dropped enough that he no longer looked like he could personally bench press a siege tower. His claws softened into human nails. His amber eyes dulled slightly, though the intensity never left.

Luci shifted next. His form slimmed elegantly, hair falling perfectly across his forehead like he had personally negotiated gravity. His aura muted but never disappeared. He still radiated that unmistakable ‘I am a royalty’ energy even as a mortal disguise.

I nodded.

“Great. Let’s go.”

I turned toward the door.

Neither of them moved.

I glanced back.

Luci stared at me in disbelief.

“…Walking?”

“Yes,” I said. “Walking.”

He looked personally betrayed.

“You can observe the academy environment,” I continued. “It helps with blending in.”

Algan stepped forward immediately, falling into position half a step behind my shoulder like muscle memory had rewritten itself into civilian escort mode.

Luci followed reluctantly, posture screaming royal inconvenience.

We stepped out of the principal office into the main administrative hallway. The polished floors reflected overhead lighting in long golden streaks. Student chatter echoed faintly from distant corridors. The scent of cafeteria food drifted faintly through the ventilation. Overcooked noodles and questionable soup.

Luci wrinkled his nose.

“…Is that edible?”

“Technically,” I said.

We exited the main building through the front lobby.

It was past dusk. But the sun hadn’t completely disappeared yet.

The academy courtyard spread out in front of us, alive with mortal normalcy. Students walked in clusters, laughing, arguing, scrolling through phones, dragging backpacks that looked heavier than their life choices.

The park stretched across the center grounds. Trimmed hedges. Flower beds bursting with seasonal color. The air smelled like grass, sunscreen, and optimism. Mortals always smelled like optimism. It was oddly fragile.

I gestured toward the east wing path as we walked.

“There are separate dormitories for male and female students,” I explained. “Faculty and mentors stay in a separate residential complex.”

Luci scanned the buildings critically. “They appear… small.”

“They are comfortable,” I corrected.

“They are dollhouses," he complained.

“They are functional," I added.

“They are economically tragic.”

Algan leaned closer to me slightly. “…He is adjusting poorly,” he murmured.

“I am hearing that,” Luci said without looking at us.

We continued along the paved path. Birds chirped in the trees overhead. A group of students ran past us laughing, one of them nearly colliding with Luci before swerving away apologetically.

He froze like someone had almost brushed a museum artifact.

“…Did that mortal just almost touch me?”

“Yes,” I said. “That will happen here.”

He looked horrified.
