I Became A Ghost In A Horror Game-Chapter 4: A Small Monster vs. A Tall Monster

Slender Man prowled the mansion, his elongated arms sweeping through furniture as he searched for the hidden children.

Dust billowed with every movement, but with no nose—no face at all—the creature showed no sign of concern.

Then, suddenly, a voice echoed from behind him.

"Hey, mister. You must not know that rummaging through someone else’s house is pretty rude."

When Slender Man turned, all he saw was a lone mirror reflecting his distorted silhouette.

His movements grew erratic.

A child's voice. A child's voice!

"Over here. What are you looking at?"

The voice came from the first floor.

Without hesitation, Slender Man teleported to the mirror-filled hall.

Mirrors.

The number had increased—there were more mirrors now than before, especially near the entrance to the second floor.

"You're fast~"

Slender Man turned.

Inside one of the mirrors, a girl stood.

Smiling.

-----

It was my first time seeing a monster other than myself.

With my small frame, Slender Man’s towering presence was suffocating.

Twice the size of an adult man.

But then I remembered—he was nothing but a pathetic freak obsessed with children.

Somehow, that thought made me feel a lot better.

In the game, there was no system for monsters to fight each other.

So what would happen?

I was genuinely curious.

And the fact that I could feel curiosity in a moment like this... Maybe I was actually enjoying this situation.

"Since we’re here, let’s play a game, pedo-mister. The rules are simple. If I slash, you get slashed. If I stab, you get stabbed."

There was no need for his consent.

From within the mirror, I gripped my knife like a brush and slashed through space itself.

The edge of my blade cut across dimensions—striking Slender Man.

A wound opened across his throat.

Crimson blood dripped down his suit.

If he were a regular person, his head would’ve been severed.

Damn, he's tough.

"!!!!"

Slender Man reeled back in rage.

At the same time, he seemed to have realized how my attack worked.

He lunged—charging straight for the mirror where I was reflected.

His elongated arm slashed through the air.

CRASH!

The mirror shattered into shards of glass, scattering debris and dust into the air like a rising fog.

Did he think that was enough to stop me?

I had already moved to another mirror behind him.

I swung again.

Slice—

"!!!!"

This time, the gash ran across his back.

He had no mouth, but his trembling frame told me he desperately wanted to scream.

A chuckle escaped my lips.

"Heh."

Hearing my laughter, Slender Man lashed out again.

Another mirror shattered.

At the same time, I slashed across his side.

This is a hall filled with mirrors.

With that lanky body of his, there’s no place to hide.

Which means—

He has no choice but to take every hit.

I zipped through the mirrors at a speed no human eye could track.

No matter how fast he teleported, his reaction time couldn’t match my movements.

Slender Man flailed wildly, attacking every mirror in sight.

But it was useless.

Every time he destroyed one, I struck him three more times.

Slash! Slash! Slash!

Left. Right. Up. Down. Down-up. Right-left. Left. Left. Up-center. Mid-down. Up-center. Down. Left. Right. Right.

A storm of blades rained down in unpredictable patterns, striking him over and over.

Blood filled the air, the scent thick, overwhelming.

For the first time in ages, I felt alive.

Whenever he showed an opening, I struck.

Whenever he let his guard down, I cut him deeper.

Some mirrors had broken, but he was covered in wounds.

His once-imposing suit was now in tatters.

And yet—he wasn’t dying.

Despite everything, he remained standing.

Even as his figure trembled, even as his arms barely moved.

Shit.

This bastard’s even tougher than I thought.

This method wasn’t going to kill him.

Which meant it was time to move to the next phase of my plan.

"Clap!"

The sharp sound of my hands meeting echoed through the mansion.

That was the signal.

From the distance—

A deafening noise erupted.

Metal clashing against metal. The clatter of pots and pans.

The children were making as much noise as possible, just as I had instructed them.

Slender Man’s head snapped toward the sound.

And in an instant—he vanished.

"Not so fast."

This was my mansion.

A place filled with mirrors. My domain.

The moment he reappeared, Kyung-min was there.

And so was I.

He reached for Kyung-min—

I sliced through his hand.

Kyung-min, terrified but determined, screamed louder.

A giggle slipped out of me.

"Kikiki~"

"!!!!"

Slender Man was furious.

Ignoring me, he teleported again—this time targeting another child.

The source of this c𝓸ntent is frёeweɓηovel.coɱ.

But I followed.

With [Mirror Travel], I could match his speed.

There—Soo-ho.

I slashed again, intercepting him before he could strike.

"I told you—it’s pointless."

Slice!

Every time he moved to attack a child, I cut him down.

I had matched his teleportation speed.

He couldn’t ignore me anymore.

For the first time, Slender Man hesitated.

Then—darkness pooled around him.

A writhing, unnatural energy coalesced at his feet.

I knew what was coming.

"Phase Two."

Black tendrils erupted from the shredded remains of his suit.

They wriggled ceaselessly, filling the air like grotesque vines.

Disgusting.

The tentacles lashed out at the mirrors, shattering them as I tried to cut them down.

At the same time, I aimed for his body.

Tch.

Not a scratch.

How is he this strong when he’s not even a boss monster?!

Slender Man pressed forward, destroying mirrors faster than I could move.

But I had already planned for this.

His Phase Two wouldn’t last forever.

All I had to do was stall.

I kept retreating through the mirrors, baiting him further.

Eventually—he reached the second-floor corridor.

And broke nearly every mirror there.

Which meant he had no choice but to follow me back downstairs.

"It's almost time, isn't it?"

His energy was depleting.

His movements were slower.

And yet—

The tentacles remained.

This was the densest part of the mansion.

A place filled with mirrors.

In his second form, he could easily shatter all of them.

The tendrils extended—reaching the ceiling, the walls, crushing everything.

Slender Man stood, basking in his so-called victory.

Even though his Phase Two had ended, the damage was already done.

The remaining mirrors on the ground were few.

Even without his tendrils, he could break them with his bare hands.

And if that happened—

I would have nowhere left to go.

Slender Man knew this.

He stood, composed, confident.

But I simply raised my hand and held up three fingers.

"You made three mistakes."

And as the last mirrors rained down like broken glass from the ceiling—

I smirked.

First mistake.

"Do you really think all these mirrors fell on their own?"

Slender Man didn’t notice it.

Didn’t see the massive mirror hurtling straight toward him.

I had used telekinesis to launch it.

And as the glass made contact, I activated one of Ella’s hidden ✪ Nоvеlіgһt ✪ (Official version) abilities—[Mirror Consumption].

The mirror swallowed him.

From the head down to his shoulders, his body was pulled inside.

Second mistake.

"You overlooked something in the children’s noise, didn’t you?"

This translation is the intellectual property of Novelight.

There were three voices.

Kyung-min. Soo-ho. Eun-jung.

But there was one child who hadn't spoken.

Ha-rim.

She had been hiding.

And now—she lunged from behind, wielding a metal candlestick.

Slender Man tried to teleport.

It didn’t work.

I had realized something while using [Mirror Travel]—

To teleport, not only do you need a destination, but you also need a clear point of origin.

Right now, Slender Man existed both inside and outside the mirror.

His location was uncertain.

And without proper coordinates—teleportation became impossible.

Third mistake.

"You assumed I couldn't deal a fatal blow."

And for that miscalculation—

You will pay with your life.

Slender Man thrashed, struggling to free himself.

But with his upper body trapped in the mirror, his arms couldn’t reach it to lift himself out.

To make matters worse, his second phase was over.

The tentacles were gone.

He had no means of escape.

I wrapped my arms around his trapped torso.

Leaning close, I whispered:

“Here’s a question. What do you think happens when someone is halfway inside a mirror... and the mirror breaks?”

CRASH!

Ha-rim’s candlestick struck the mirror.

Shattered it.

The part of Slender Man inside the mirror vanished.

The rest of him—

His lower half—collapsed, lifeless.

From another mirror, I whispered mockingly:

"The correct answer is... ‘You get split apart.’"

"How pathetic~"

I traced my fingers over Slender Man’s remaining torso.

His faceless, mutilated form.

"......Hah!"

My mind snapped back into place.

What... what the hell did I just do?

I had been excited by the scent of blood.

I had mocked him.

And worst of all—

I actually said ‘how pathetic’ like some smug brat.

Was I turning into a damn gremlin?!

Maybe...

Maybe Ella’s body was influencing me more than I thought.

I was still human—but in this world, I was also a monster.

Still, to actually say ‘how pathetic’ like some cringey anime villain...

I needed to throw this thing away.

But just as I was about to discard Slender Man’s remains—

His body... dissolved.

And turned into smoke.

The black fog seeped into me.

"?!?!"

I felt it.

Power.

Flowing into me.

Could it be...

No—

I would think about that later.

For now, the fight was over.

A complete victory.

Just a while ago, I was an ordinary person.

And now, I was fighting to the death with supernatural entities.

What the hell happened to my life?

The children, cautiously stepping over shattered glass, slowly approached me.

They hadn’t run yet.

Perhaps because Ha-rim was standing in front of me, blocking their escape.

I could feel their fear.

They had witnessed Ella’s true power.

Understood that if she wanted to, she could tear them apart like paper dolls.

The scene of carnage still reflected in the mirrors.

And at the center of it all—

I was smiling.

"Now then, it’s time to keep your promise~"

How long did I have to keep up this cutesy, third-person Ella act?

It felt ridiculous.

But changing my speech pattern now would only make things more suspicious.

I had demanded a playmate.

But they all knew what that really meant.

A ‘playmate’ was just another word for a disposable toy.

I didn’t actually need to threaten them anymore.

But if I suddenly became too kind, they would definitely notice something was off.

So, I maintained my Ella-like tone.

"Ella needs a new friend to play with. Since I helped you so much, I’ll be nice and only ask for one person~"

"We can’t... we can’t just leave someone behind."

"Oh my! How wonderful! That means... you’ll all stay and play with me?"

Ha-rim trembled.

She was no different from a mouse cornered by a predator.

She kept answering, kept talking, but she needed to act fast.

Or else—

One of them would end up as a broken toy.

"We’ll play with you... but... we’re exhausted. Can’t we rest first? Please?"

Oh? So that’s the angle you’re taking?

Smart kid.

Even knowing they could die at any moment, she was still bargaining.

"Hmmm..."

Gulp.

I could hear Ha-rim swallowing nervously.

She was probably picturing me suddenly rejecting her request and slashing them down.

If it were the real Ella—

She might have.

But I wasn’t her.

"Well~ since we played so much tonight, I suppose I’ll let you rest~ Just don’t do anything sneaky, okay~?"

"!! Y-Yes! Of course!"

Relief washed over Ha-rim’s face.

Good.

You’ve been through enough, kid.

You need to rest.

I led them to the second floor.

On purpose, I picked a room without any mirrors.

They were already traumatized enough as it was.

"Ah~ guiding you guys is so hard with all the mirrors broken~"

"......!"

I let that line slip casually.

But I knew they would understand.

The second floor still had a few remaining mirrors.

If they destroyed the rest, chasing them would be much harder.

This is your best chance to escape.

Make good use of it.

I vanished into the mirrors, leaving them behind.

And, silently—

I told them goodbye.

-----

Behind the closed door, the children finally exhaled.

Even standing near Ella had made breathing difficult.

They had bought themselves time.

But next time they played—

Someone would die.

"Is everyone okay?"

Eun-jung asked.

Everyone nodded.

Kyung-min checked the room.

"There are no mirrors here. We’re safe."

Hearing that, the group finally relaxed.

"Ha-rim, thanks to you, we bought some time."

"No, I should be thanking you all for staying strong."

They comforted each other.

Ha-rim wiped the tears from Eun-jung’s eyes.

For now—they were all still alive.

"What do we do now? Just wait for morning?"

"Probably. There might be more monsters in the forest..."

"Wait! What about our phones? Maybe we can call for help!"

They had completely forgotten.

There had never been a chance to make a call.

Soo-ho pulled out his phone.

No signal.

Same for Kyung-min, Eun-jung, and Ha-rim.

"Damn it. Just like a horror movie."

"And this time, the ghosts are real."

They agreed.

They would escape at dawn.

Using blankets, they began tying ropes.

But as exhaustion hit—

One by one, they fell asleep.

Except for Ha-rim.

She searched the room.

And there, hidden within the shadows—

She found [Ella’s Diary].
