Reborn as Eren Yeager: The Gacha System

Morning sunlight filtered through the curtains as Eren quietly slipped out of bed.

The house was silent.

Carla was still asleep.

Grisha had left before dawn to visit a patient in a nearby village.

Perfect.

Grabbing a small wooden backpack, Eren stepped outside.

His destination wasn’t the training field.

Nor the market.

Instead, he headed toward the abandoned storage district near the edge of Shiganshina.

Most people avoided the area.

Old warehouses, broken fences, and collapsing buildings filled the district.

Children believed it was haunted.

Adults simply thought it was unsafe.

To Eren...

It was perfect.

"No one comes here."

He pushed open the rotten door of a forgotten warehouse.

Dust danced in the sunlight.

The smell of old wood lingered in the air.

Months ago, he had discovered the building while exploring with Armin.

Since then...

It had become his secret base.

Walking toward the back wall, Eren removed several loose wooden planks.

Behind them lay a small hidden compartment.

Inside rested neatly stacked supplies.

Dried meat.

Clean water.

Blankets.

Medical herbs.

Candles.

Rope.

Simple knives.

None of it looked impressive.

But if Wall Maria fell tomorrow...

These supplies could mean the difference between life and death.

Eren carefully added today’s contribution.

A small bag of dried potatoes.

Then replaced the wooden boards.

"Ding."

A familiar notification appeared.

Emergency Supplies

Reward:

2 Rare Gacha Tickets

Current Evaluation:

Bonus Objective Added.

Store medical supplies.

Random Utility Item.

Eren smiled.

"Medical supplies..."

That wouldn’t be difficult.

With Grisha as his father, obtaining herbs and bandages over time wouldn’t attract suspicion.

Later that afternoon...

"Eren!"

Armin waved excitedly from across the street.

"I found another book!"

Eren laughed.

"You always do."

"This one’s different!"

Armin opened the worn notebook.

"It’s about old military logistics."

Military logistics?

Eren immediately became interested.

The two boys sat beneath a large tree while Armin enthusiastically flipped through the pages.

"There."

He pointed toward a rough illustration.

"When soldiers transport supplies, they hide emergency stockpiles along their route."

Eren’s eyes widened slightly.

Emergency stockpiles...

His hidden warehouse.

The idea was almost identical.

"Why are you smiling?"

Armin asked.

"I was just thinking."

"About what?"

"You’re smarter than you realize."

Armin blushed.

"N-No, I’m not."

"You are."

Eren answered honestly.

"One day...

People will depend on your ideas."

Armin laughed awkwardly.

"I don’t think that’ll ever happen."

Eren remained silent.

One day...

Humanity itself would depend on Armin.

That evening...

Eren returned home to find Mikasa helping Carla prepare dinner.

Although she had been living with the Yeagers for quite some time now...

She still spoke very little.

Carla looked up and smiled.

"Perfect timing."

"Eren, can you chop these vegetables?"

"Sure."

As they worked together, Carla suddenly spoke.

"You’ve been growing up so quickly."

Eren froze.

Had she noticed something?

She smiled warmly.

"You’re always helping people."

"Helping your father."

"Helping Armin."

"Helping Mikasa."

"I’m proud of you."

For a brief moment...

Eren couldn’t answer.

Instead...

He simply nodded.

His chest felt strangely heavy.

Every kind word from Carla made the future hurt even more.

Noticing his silence, Carla gently rubbed his hair.

"What is it?"

"...Nothing."

"You can tell me."

Eren looked at her.

Then smiled.

"I was just thinking..."

"I’m lucky."

Carla laughed softly.

"No."

"We’re the lucky ones."

That night...

Unable to sleep, Eren climbed onto the roof of the house.

The stars filled the sky.

Beautiful.

Peaceful.

A world untouched by Titans.

For now.

"Ding."

Daily Login Reward.

Claim?

"Claim."

A small wooden chest appeared.

Opening it revealed...

Reward:

Common Item.

Traveler’s Water Flask.

Quality:

Excellent.

Description:

Keeps water fresh significantly longer.

Eren chuckled.

Another survival item.

The system really wanted him prepared.

He wasn’t complaining.

Every useful tool increased his chances.

No matter how small.

The next morning...

Grisha invited Eren to accompany him on house calls.

Normally, Eren accepted gladly.

Today was no different.

As they walked through Shiganshina, Grisha spoke.

"Being a doctor isn’t about curing everyone."

"It’s about doing everything you can."

"Sometimes..."

"...even your best won’t be enough."

Eren quietly listened.

Those words struck deeper than Grisha intended.

Because Eren already knew there would be people he couldn’t save.

No matter how hard he tried.

No matter how prepared he became.

The question wasn’t whether someone would die.

The question was...

Who?

As they turned a corner, Grisha greeted another family.

Eren followed behind—

Then suddenly stopped.

Danger Sense activated.

A faint pulse.

Weak.

Almost unnoticeable.

Someone...

Was watching them.

Eren subtly glanced around.

Merchants.

Children.

Soldiers.

Nothing unusual.

Yet the feeling remained.

He resisted the urge to use Observe immediately.

Instead, he continued walking beside his father.

A few seconds later...

The sensation disappeared.

"...Interesting."

Eren murmured.

This was the third time Danger Sense had reacted without revealing a clear target.

Either someone inside Shiganshina possessed exceptional awareness...

Or the system was warning him about something much larger than a single person.

Whatever the answer...

One thing was certain.

The countdown to disaster wasn’t the only clock ticking anymore.
