The Useless Extra Knows It All....But Does He?

I crouched in the shadows, just out of sight, heart hammering in my chest. The air here was wrong—dense with corrupted mana, thick enough to taste. I could feel it pressing against my skin like oil, seeping into my bones. I shouldn't have been here. No one should have.

But I had to know the truth.

The whispering strand of blue hair—enchanted minutes ago—had latched itself to the hem of Emeron's cloak. From this distance, it carried every sound around him back to me in a whisper only I could hear.

Below, Emeron knelt inside a hidden cavern.

The red glow of twisted ley lines lit his figure in monstrous silhouette, casting jagged shadows that danced across the cursed stone walls. The floor itself pulsed—jagged runes flickering like wounds in the world's mana stream, ancient and angry. I recognized none of them. That terrified me.

Emeron wasn't trembling now.

He was reverent.

In his gloved hand hovered a dark communication crystal—oval, obsidian black, threaded with flickers of violet and crimson. It pulsed faintly… like a living eye.

Then I heard it—through the whisper-spell in my strand:

"Report."

The voice was inhuman. Cold. Hollow. It sent a chill through my entire body.

Emeron bowed lower, forehead nearly touching the cursed runes.

"Sabotage is in place, my lord. By tomorrow, the regulators will fail. Beasts will frenzy. The failsafes on student wristbands will not activate. The dungeon will devolve into chaos."

My breath caught. The words didn't make sense. No, I didn't want them to make sense.

But I couldn't stop listening.

The crystal pulsed harder now. I saw the way Emeron's hands trembled when the voice asked again:

"And the Blood Crystal?"

His fingers hesitated.

Then he reached into his cloak and withdrew it—a jagged shard, red as fresh blood, beating like a second heart. The corrupted mana around it warped the air, turning it sticky, toxic.

I'd seen relics like that before. In history books. Sealed vaults. Places meant never to be touched.

"It is here," he said. "Unused."

"Use it."

He paused. I could almost hear the fear in his breath through the strand.

"My lord… that would cause massive destabilization. The magic grid will fracture. The entire illusion may collapse. It could draw suspicion—"

"Do. As. You. Are. Told."

The voice changed—sharper now, molten with fury. The crystal shrieked, black veins of raw mana splintering across its surface, leaking something that felt more like malice than magic.

Emeron collapsed fully to both knees, gasping.

"I will obey. As you command, my lord."

And just like that… silence returned.

The crystal dimmed. The shadows stilled. The cavern exhaled.

Emeron… what have you done?

I swallowed hard, forcing down the rising bile and fury clawing at my throat. My hand trembled, not out of fear—but rage. Betrayal. I wanted to scream, to attack, to drag him into the light and make the world see what he had become.

But I couldn't.

I needed to warn the Vice Dean. I reached for my communicator crystal, fingers numb. Nothing. Static. A wall of silence greeted me. A jamming ward? No—it was more intricate. Specialized. Probably tied to that corrupted crystal he used. Damn it.

As I tried to gather my thoughts, I noticed movement. Emeron was heading upward—toward the dungeon dome.

I followed him, teeth gritted, every nerve on edge.

And then— I realized where we were.

The passage led to the very boss chamber itself. He could enter the dome from here? Gods… that's how he planned it.

He approached the sleeping dungeon boss. The moment he raised the Blood Crystal—

I stepped out. I couldn't stay silent anymore.

"Emeron."

He froze.

Then slowly turned. His figure stiffened for a fraction, but he wore that same placid smile.

"Ah, Professor Seraphina. What a surprise. What are you doing here?"

My voice came out ice-cold. "Enough with your crap. I know what you're doing."

His smile twitched. Then it twisted.

"You shouldn't have gotten involved, Seraphina. You always were too curious. Now I have no choice... I'll kill you here—and the students, too."

His words hit me like a hammer to the gut.

I charged.

We fought.

I gave it everything—every spell, every drop of mana I could conjure. But his magic… it wasn't his. It was corrupted. Rotten. Infused with something darker.

He was stronger.

My attacks twisted in the air. The very mana betrayed me. The corrupted field warped everything.

Still—I didn't stop.

I screamed at him.

"I won't let you touch them! I won't let you lay a finger on my students!"

But it wasn't enough.

I fell.

Pain tore through me. Blood spilled from my lips.

I could barely see—but I saw him.

I saw him embed the Blood Crystal into the dungeon boss's core.

I couldn't let him win. I forced my legs to move.

I turned and ran.

Not out of fear—never fear.

I had to warn them.

But the path… The path was gone. Or changed. Redirection glyphs. Illusions. Curses.

That bastard. He knew. He knew I'd run.

That's why he let me.

I was lost in a maze of cursed stone, bleeding out with every step. No potions. No scrolls. Nothing.

Because I didn't expect this. Gods, I didn't expect this. My legs shook. My lungs burned.

I thought—maybe I could go back. Maybe I could destroy the boss. Destroy the crystal.

But even breathing hurt. Even standing hurt.

I couldn't. Damn it. Damn it all.

Was there nothing I could do?

…No. I could at least clear the monsters.

Even if I was dying—I could do that much.

If I could thin the herd… maybe I will be able to save some students.

So I fought.

I don't know how many fell. I don't remember their shapes, their faces, their screeches.

I only remember the blood. My own. Theirs. The pain. The fire in my limbs.

Then—Black. I collapsed. I don't know how long I was out.

But when I woke—

I heard them. Fighting. Shouting. Students. They were here. They were facing it. No. They couldn't win alone. I had to help them. Even if it killed me. I rose, staggering, bleeding, weak—but I moved toward the sound—and then I heard it...

"Professor Seraphina has betrayed us. She was the one behind this entire attack."

Emeron's voice, clear and venomous, rang out across the clearing.

For a moment, I thought I had misheard. That my battered mind was playing tricks on me. But no.

He had said it. He had painted me the villain.

Gasps followed. Murmurs. Doubts.

"No… That can't be," Kyle's voice, trembling.

"Professor Seraphina…?" Aiden.

"She would never—" Selena.

"She trained us… she protected us…" Lilliane.

Each word drove deeper into my chest, carving a pain I hadn't felt even when Emeron struck me down.

Their disbelief… their hesitation…

It shattered me.

I wanted to scream—to cry out and tell them the truth, to shake them until they understood I would never harm them. That I had bled for them. Fought for them.

But I couldn't.

My throat burned. My lungs felt like they were collapsing with each breath. I couldn't force the words out.

I took another step forward, but my knees buckled, and the world blurred.

I saw weapons rise.

Students—my students—raising their swords against me.

Some trembled. Some hesitated. But they all believed him.

He had twisted everything.

Emeron stood tall, commanding, righteous. And I—I looked like the monster.

Gods… how had it come to this?

And then…

He moved.

Luca.

Not toward Emeron. Not toward the others.

Toward me.

He caught me before I could fall, his arms steady around me. His scent was sweat and iron, his hold gentle but firm.

I blinked up at him, barely able to focus—and saw no fear. No confusion.

Only concern.

From his satchel, he pulled out a potion and held it to my lips. "Drink," he said, voice low.

His hand supported mine, guiding it. My fingers barely had strength to hold the bottle.

Behind him, voices rose in outrage and disbelief.

"LUCA?!"

"What are you doing?!"

"She betrayed us!"

"She's the enemy!"

But he didn't flinch.

He didn't listen.

His eyes never left mine.

"Are you alright?" he asked.

And in that moment—

I broke.

Because no one had asked me that. Not since this nightmare began. Not once.

I had fought in silence. Bled in darkness. Watched everything I believed in collapse.

And yet… he asked.

I could see the concern in his eyes.

A tear slipped from my eye, trailing down a face smeared with blood and dirt.

I was too exhausted to smile.

Too shattered to speak.

But I held his gaze.

And for the first time in what felt like forever…

I didn't feel alone. He ..he believed in me , but why?

****

I rummaged through my pockets, fingers trembling, searching—anything, anything that could help. Another potion, a salve, a healing charm. Seraphina needed to recover, even just a little. Because I knew… without her, in the fight that was coming next, we wouldn't survive.

Shouts rained down on me—accusations, confusion, anger. But I didn't move. I kept kneeling beside her.

And then—

"Do you know what you're doing, Luca?"

Vincent's voice cut through the chaos.

I looked up.

His gaze was unreadable. Cold. Sharp.

But I didn't flinch. "I do."

For a heartbeat, silence.

Then… Vincent stepped forward. His body shifted slightly—just enough to stand between us and the others. From his cloak, he pulled a small glass vial and handed it to me without a word.

A stronger potion.

Then he raised his shield and stood tall—facing everyone, protecting us.

I blinked.

Vincent… He believed in me that much?

Something stirred inside my chest. A strange, unfamiliar tightness. Heavy and warm.

I glanced back at Emeron—so composed, so commanding. If I hadn't known the truth… if I hadn't seen it myself…

Maybe even I would have stood by him.

But I did know.

And now—

Now they did, too.

"Elowen," I heard someone say.

She stepped forward, a soft glow in her hand—an herbal tincture, a spell-wrapped poultice—and knelt beside Seraphina, offering it gently.

Kyle strode up next, arms folded. He nodded once and muttered, "Hmm… I believe in my brother-in-law too."

I blinked. "Huh?"

Did he just—

No, no. Stress. I'm hearing things. Definitely not the time.

Aiden lowered his weapon.

Selena's wand dipped slightly.

Lilliane stepped back, biting her lip.

One by one, they moved away from Emeron.

No fanfare. No dramatic declarations.

Just trust.Trust in me.

I had rehearsed so many things in my mind—speeches, truths, logical breakdowns—to convince them. Prepare for every doubt, every denial.

But none of them came.

They believed.

In me.

And for the first time in my life… I didn't feel like I was in this world alone.

I felt seen.

Trusted.

It hit me harder than I expected.

Warmth bloomed deep in my chest—burning away the loneliness I didn't know I still carried.

But the moment shattered.

Emeron's smile twisted.

Then he laughed.

Low, unhinged, venomous.

"Good. Good! I was planning to let you all turn on each other first… make it easy. Pick you off one by one…"

He stepped forward, mana surging like a storm cloud around him.

"But now—you leave me no choice."

From the tall grass at his side, he reached down and pulled something out.

A figure.

A student.

Bound, unmoving, barely breathing.

My heart sank.

My eyes sharpened.

"E....eric"
