Coin’s Edge: Reincarnated as a Extra

His heartbeat thumped relentlessly.

And so did his head.

His entire body felt like it was about to ignite.

"Damn it! The real culprit is my hormones in this young body."

Even though he carried the soul of a 25-year-old man, he couldn't resist the waves of emotion and desire that overwhelmed him.

But it was understandable. After all, a man was still just a man.

While Hector remained in this awkward state, Berry, who stood nearby, began her next move.

"If you surpass me, you'll receive a gift from me," she said in a seductive tone that could persuade any man to agree.

Of course, Hector was no exception.

Standing before the massive stone, Hector's expression shifted slightly.

A strange urge was pulling him forward, as if her earlier words were a kind of potion.

He sighed, trying to clear his thoughts.

"Damn... that girl is dangerous... I have to keep up with her somehow."

However, his body refused to obey that calm reasoning.

He immediately dropped into a fighting stance and took a deep breath. It was obvious—he wanted to uncover what she truly intended for him.

"This is the first time I've used the new mana with a clear mind."

Then, his skin began to stiffen and swell as it was coated in red mana.

"Urgh!"

Suddenly, a wave of pain struck his head, flooding his mind with dark thoughts.

He struggled to regain control while sweat trickled down his forehead.

His breathing grew uneven, but after a few moments, he finally stabilized.

He exhaled slowly, as gently as he could, and muttered through heavy lips:

"Just negative thoughts... as long as not that kid."

So, he stopped digging into the darkest parts of himself, just dark enough to be average.

"Yeah! Just think about that damn lunatic! Remember, I want to kill him just as much as I want anything else."

"Damn patient nearly strangled me to death."

While he was absorbed in his own thoughts, he hadn't noticed that the prisoners around him had already backed far away to avoid being crushed by the force of his unleashed mana.

All of them stared at him with horrified expressions.

"That's too strong! Way more than any of us!" one prisoner grimaced, watching the mana swirl around.

"Yeah. It's even stronger than before."

Everyone kept their eyes fixed on Hector, waiting to see what grade he would receive.

Could it surpass Berry's grade—the one currently regarded as the strongest?

Eventually...

Every prisoner held their breath, anticipating Hector's next move—until a deafening noise suddenly echoed across the area.

BAAM!

It was the purest sound they'd ever heard… like metal colliding with metal.

Once again, Hector shocked everyone as his punch slammed into the huge stone—

And almost instantly, the massive stone cracked nearly to its core.

Countless fracture lines ran across its surface, deep dents left by the sheer force of his blow.

But now, this had caused a new problem.

"So... what grade will he get?" a nearby prisoner asked, narrowing his eyes at his companion.

"Who knows… but does it even matter now? No one here can top him anymore," the fellow prisoner shrugged, shaking his head as he expressed his opinion.

While the prisoners murmured among themselves, the jailer silently scribbled something into his notebook, eyes locked on Hector with a tight, unreadable gaze.

Each stroke of his pen marked the page until he paused, then stopped altogether.

"Done... You really are a special product," he muttered. "Perhaps… our experiment could come to an end soon."

He slowly closed his notebook and let out a light sigh, glancing around the room with a bored expression.

After several seconds, he took a deep breath—

Then shouted loudly:

"Prepare for the second experiment!"

***

One hour later.

All the prisoners were ready — their minds as steady as possible in the face of death — for what was rumored to be the most dreadful experiment of the day.

The torture chairs stood before their eyes.

None of them wanted to ever see those things again in their lives.

To them, it was the worst kind of nightmare — something they would be forced to confront directly.

However, one person didn't seem to share that fear.

"I don't see anything related to danger or death," Hector muttered, eyes fixed on the torture chair as he casually chewed on the capsule — the reward he had just received.

And honestly, Hector wasn't wrong.

It was just an ordinary-looking chair.

No threatening parts, no blood, no grotesque decoration.

Anyone who glanced at it from the outside would never guess it was a torture device for prisoners.

And yet… everyone here stared at it as if it were some kind of monster.

"Haha…" Tyrone chuckled in a way that barely resembled a smile.

"You're right — but that's just the shell... The horror lies inside the chair."

He added in a firmer tone: "It's a C-rank artifact."

"The artifact has the ability to link emotions — everyone will experience the same feeling simultaneously!"

Tyrone said, his face glowing with excitement as he stared at the torture chair, clearly eager for the show to begin.

Hector narrowed his eyes slightly, unsettled by Tyrone's twisted enthusiasm.

"What's wrong with this guy?" he thought, then sighed. "Ah, right… I forgot. He's a lunatic, too."

He looked back at the torture chair, now even more suspicious, and asked,

"So... who's sitting in it next?"

Hector's question made sense.

Only two chairs stood before them, connected by a strange steel cable — yet their purpose remained unclear, especially to someone who hadn't experienced it before.

Silence.

"Haha… Buddy, you're the one sitting in it," Tyrone said, shaking his head slightly while curling the corners of his mouth.

Then he slowly pointed his finger toward Hector.

And this time, all the prisoners turned their eyes to him as well.

A heavy, fearsome silence hung in the air until Tyrone smiled again and continued:

"Because you're number one."

"You possess the strongest mana of us all."

"Your mana... will kill everyone."
