"Enough with the grim talk. Check on Heidemarie first. She's shaking like a deer." Everyone's attention turned at once at Chloe's words, and only then did Heidemarie clutch her trembling hands. "...Heh. I said that, but I can't help being nervous. This might be too much for a student to handle. Heidemarie, it's not too late to turn back, if you want to." Chaos rooted in the planet Ellinad, the 'Theater of Illusions.' The Theater of Illusions suddenly triggered an additional bloom for reasons unknown. Its influence spread instantly, consuming even Ellinad's Second Pioneer Base. Countless casualties occurred as a result. And that number continues to rise at an explosive rate even now. It was the greatest disaster Heidemarie had ever witnessed.

But her companions remained calm. "That's disappointing, Heidemarie. I thought after a few missions, you'd learned to trust us. Don't worry. You won't have much to handle. Just think of it as getting used to real combat with us." "Mev, talking like that won't relax anyone. I'll show you how it's done. So... Heidemarie, three Protos are participating in this operation. One of them is said to be exceptionally capable. So don't be too afraid. If things get really bad... just throw Mev in as bait and run. That idiot will survive somehow." "What?" Evie's joke lightened the mood.

Heidemarie took a deep breath and looked at her companions. People walking into the flames without hesitation. Faces smiling as if nothing was wrong. Right. It's the same mission. No one is tense. Nothing has changed about what we have to do. Trust them. I'm the only one overthinking this. That's what she told herself.

2. The Scattering Platoon

3 lines

Three hours since mission start. Terrain twisted by the influence of Chaos. Screams and cries of the people. Blaring alarms that numbed the ears. [-kzzzt.] Reports continued to pour in through the communicator. [SS Edenity 3rd Platoon, facing annihilation...] [Area 5, additional collapse... kzzzt... rescue impossible...] [Requesting support...repeat, support... kzzzt...] The Chaos storm raged without pause, and rescue operations grew increasingly difficult.

"Mev...!" Even Evie showed unease, and all eyes turned to Mev. "...This won't work." Mev spoke, as if coming to a decision. "At this rate, all the survivors will die. We split up. Right now, protecting them matters more than rescuing. Khalia, head to the civilian residential area in Area C. Evie, you're with me. We're heading to the emergency bunker in Area A. Chloe, support the first Protos. And lastly, Heidemarie, you go to Area D—" He stopped mid-sentence. His gaze shifted to Heidemarie's trembling hands. "...No. You focus on rescuing civilians while we buy time." Reading his intent, Heidemarie raised her voice. "I-I can fight too!! I'm a combat agent, how can I—" "You're going to fight like that, shaking? That's an order from your commander."

At Mev's words, Heidemarie fell silent. Even now, her hands were trembling. "Heidemarie. I told you, it's enough for a rookie to get used to real combat. You won't be able to avoid fighting entirely. Just... keep a little distance from the most dangerous areas. Understood? From Area A to D is within the Protos' assessment range. Stay within it." The others seemed to feel the same as Mev. Seeing their expressions, Heidemarie had no choice but to nod. "Alright. Go with Khalia first. The residential area in Area C hasn't been fully consumed yet. Once you're done, regroup with us. The communicator frequency is—" "I-I've set it." "Split up." At Mev's command, everyone moved in different directions.

Smile

Ellinad, Second Pioneer Base, Area C

Young Heidemarie

Transferring survivors!

Male in his 30s, suspected left rib fracture! Scalp laceration, no external bleeding. I'll leave the rest to you!

As soon as Heidemarie handed over the bleeding man to the pioneer base Agent, she asked.

Young Heidemarie

Has the number of missing persons been confirmed?

SS Edenity Agent

Thirty-nine people have been counted by officials. We just rescued three more...

No, Heidemarie! Take a breather first!

Ignoring the suggestion, Heidemarie rushed back into the scene.

Ellinad Second Pioneer Base

She shouts into the communicator.

Young Heidemarie

This is Heidemarie! Three survivors secured, currently re-entering the scene!

Requesting situation briefing!

The communicator emits a brief static noise.

Communicator

[Static.]

Through the communicator, the sounds of intense combat mixed with monster roaring could be heard.

Khalia

[This is Khalia. Four Agents currently holding position at Residential Area 43-1, 3rd floor. Maintaining blockade against monster entry to 1st floor.]

[Multiple hostiles, continuous pressure.]

[Heidemarie, remaining personnel?]

Even at the simple request, her mind went blank.

The withdrawal of combat Agents depended on how quickly she could rescue the survivors.

She took a deep breath and steadied herself.

Young Heidemarie

Re-reporting! Total of thirty-nine missing persons counted! Ten newly confirmed deceased, three rescued! Maximum estimated survivors: twenty-six!

After a brief silence, a response came back.

The noise over the radio was growing louder.

Khalia

[Confirmed. Six civilians taking shelter on 2nd floor of Residential Area 43-1.]

[Proceed to that location and recover remaining personnel.]

Young Heidemarie

Wh-what's the route?

Khalia

[East corridor collapsed. Use west staircase. Be cautious—there may be remaining hostiles.]

Young Heidemarie

Understood!

Ellinad Second Pioneer Base, Indoors

As she tears open the door, she sees a trembling family of six people.

To reassure anxious civilians on site, rescue Agents must always smile.

She recalls the advice Khalia once shared.

Heidemarie forced a smile.

Young Heidemarie

Everyone, please don't worry. You're safe now. Is anyone having difficulty moving?

Communicator

[Static.]

Khalia

[This is Khalia. One Agent KIA. Retreating from Residential Area 43-1, 3rd floor. I repeat, retreating from Residential Area 43-1, 3rd floor.]

[Heidemarie, if you're on the 2nd floor of Residential Area 43-1, get out as quickly as...]

Heidemarie lowered her voice, concealing Khalia's transmission.

The survivors mustn't become anxious.

Ellinad Second Pioneer Base

Heidemarie was running urgently, carrying a rescued child in her arms.

Young Heidemarie

Huff... huff... P-please hurry! The shuttle is about to depart!

Though she used the shuttle as an excuse, the slower the survivors moved, the longer Khalia and the Agents would have to remain on site.

Without realizing it, she found herself asking the rescued to hang in there.

As they reached the point where the Pioneer Base Agent was visible, she shouted.

Young Heidemarie

Just run to where you can see over there! I'm sorry, but I need to return to the field!

Heidemarie set the child down and turned around.

She turned up the volume on her communicator again.

At the same moment the radio crackled over the public frequency, a middle-aged woman appeared before Heidemarie.

The woman was pointing at the debris of a collapsed building.

Middle-Aged Woman

Please help! There are still people over there! My husband...!!

Mev

[This is Mev...static... isolated...requesting support...static...]

Evie

[This is Evie...! requesting support...static...]

Middle-Aged Woman

Please...! Please help! He's a man who's worked his whole life!! He's devoted his entire life to me and our family!!

In this moment of conflict, someone's voice echoed in Heidemarie's head.

Past Reminiscence

Chloe

Promise me, Heidemarie.

You have to promise.

Ellinad Second Pioneer Base

Heidemarie looked back and forth between the communicator and the collapsed building... and made her choice.

Because that was the promise.

Young Heidemarie

...Please guide me to your husband!!

Ellinad Second Pioneer Base

Middle-Aged Woman

Thank you...! Thank you!!

After rescuing the middle-aged woman's husband and three additional people, Heidemarie picked up her communicator.

Young Heidemarie

This is Heidemarie! Khalia, requesting status report!

Static.

Khalia

[This is... Khalia...! Currently only one Agent and I remain.]

Khalia's voice, breathless.

Khalia

[Protecting four civilians. Can't hold out much longer.]

[Agent Heidemarie, requesting support at Residential Area 34-2. I repeat, requesting support at Residential Area 34-2.]

Young Heidemarie

(Khalia is requesting support...)

Heidemarie felt her blood run cold.

Young Heidemarie

Heidemarie, entering the field now!

Khalia

[Ugh, confirmed one enemy breaking away...! High probability of contact. Maintain vigilance while moving!]

As Heidemarie headed toward the field, a monster that had broken away from the group revealed itself.

4. Khalia

226 lines

Khalia

Ellinad Second Pioneer Base

After defeating the monster, she stood up.

Too much time had been wasted.

Even during combat, she had heard Khalia's transmissions over and over.

Khalia

[This is Khalia. Requesting support.]

[This is Khalia. All Agents except me have fallen in combat. I repeat, all Agents except me...!]

[Can't hold out any longer...! Civilians are dying!! No!!]

[This is...! Ugh!!]

[Heidemarie!!! Where are you!!!]

Heidemarie recalled Khalia's last transmission as she sent her signal.

Young Heidemarie

Khalia...! Cough! I'm... I'm re-entering now!

Sorry it took so long...

Then, with a tremendous sound, the ground shook.

Building 34-2, where Khalia had entered, began to collapse.

Heidemarie stood frozen, watching the scene.

Young Heidemarie

...Khalia?

Heidemarie

...Khalia.

If only I had been a little faster.

If only I had been a little stronger.

...could I have saved you then?

Mev's Request

Deep within Area A, Ellinad Second Pioneer Base

Young Heidemarie

This is Heidemarie! Mev, can you hear me?

A transmission she had sent hundreds more times while heading toward the interior of the command center.

Communicator

[Static...]

No answer came, but Heidemarie tried persistently.

Young Heidemarie

This is Heidemarie! Please respond!

The radio signal was poor due to Chaos's influence.

The interference was getting worse.

Young Heidemarie

Ugh...!

Finally, Heidemarie pleaded into the communicator.

Young Heidemarie

Mev! Mev!! Can you hear me? It's Heidemarie! Please answer if you can hear me! Please...!!

Khalia...! Khalia is trapped under the building...!

I need help... sob, Evie too, Evie's bleeding so much...

Communicator

[Static...]

Mev

[...crackle...marie...]

Young Heidemarie

Mev? Is that you, Mev?

Mev

[...demarie. The signal...crackle...unstable...]

Young Heidemarie

Please wait!! I'll go deeper inside!

Heidemarie felt relief at Mev's voice and headed deeper into the command center.

Her anxiety about her dying companions far outweighed her fear of the Monsters she might encounter.

Young Heidemarie

Mev? Can you hear me? It's me, Heidemarie...!

Mev

[Static...I hear you. Heidemarie, what's the situation?]

Just like with Evie, Heidemarie couldn't bring herself to tell Mev about Khalia.

For now, she only mentioned Evie.

Young Heidemarie

I met up with Evie...! Mev, Evie's not in good shape.

I gave her first aid, but I don't know how much longer she can hold on.

Where are you, Mev? I heard you needed support.

I... I fought a lot of monsters on my way here too.

I can help, so if you tell me your location, I'll come to you.

Let's take Evie and get out of here together!

Communicator

[Static...]

Young Heidemarie

...Mev?

Mev

[...I wish we could, but I don't think that's going to be possible.]

Heidemarie froze in place, stunned.

Young Heidemarie

...What?

Mev

[The injuries are too severe to move. I can't secure an escape route either.]

[...Evie's still holding on, right?]

Young Heidemarie

...Ma, Mev...!

Mev

[Heidemarie... I have a favor to ask.]

At Mev's firm tone, Heidemarie's lips trembled.

Young Heidemarie

...What?

Mev

[Haa...haa... If you promise me just one thing, I think I'll feel much better.]

[We've risked everything to rescue people, but...]

[...I have a personal wish too.]

[Protect Evie, Heidemarie.]

[Just that one thing....]

[Can you promise me?]

Young Heidemarie

Mev... all of us together...!

A monster's roar echoed through the communicator.

Mev urgently sought confirmation.

Mev

[Heidemarie...! Ugh, promise me...! There's no time...!]

Heidemarie answered through her tears.

Young Heidemarie

Yes...!! Yes! I promise!! I'll definitely protect Evie...!

At her promise, Mev's voice became much more at ease.

Mev

[...Thank you.]

Soon after, a horrific scream rang out over the radio, then cut off to nothing.

Heidemarie, who had been frozen in the nightmare, turned around in an instant.

This wasn't the time to grieve or despair.

To keep her promise to Mev, she had to get back to Evie.

But at that moment, a monster crawled out from the end of the corridor, shaking the building.

Mev & Evie

Ellinad Second Pioneer Base, Indoor Area A

Blood flowed, obscuring her vision.

Her exhausted body trembled, losing control.

Something was wrong with her leg too, it was hard to walk straight.

Still, Heidemarie got up and moved toward Evie.

Supporting herself with blood-soaked hands, she turned down the corridor.

Young Heidemarie

Evie... Mev said she'd come later, so we should head back first...

......

Where Evie should have been, only bloodstains remained.

Heidemarie's body, which had been struggling to hold on, slowly collapsed.

Young Heidemarie

E...vie?

Her dust-covered fingers groped across the sticky pool of blood as if searching for the person who had been there,

but no answer came.

Heidemarie

......

Mev, Evie.

Thanks to the two of them guarding Area A, countless lives were saved.

You know what? If it weren't for those two, the monsters would have pushed all the way to the command center.

Heidemarie laid Evie's notebook before Mev's grave.

Inside the notebook was a hastily scribbled sentence.

[Mev! We're having a baby! You're in big trouble now!]

Heidemarie

......

Evie... *sob*, I'm sorry.

Mev... I'm sorry.

Heidemarie closed her eyes in apology.

Chloe

Ellinad Second Pioneer Base, Area B

The surroundings grew increasingly chaotic.

Before long, it became impossible to even tell which direction led to escape.

Monsters were closing in, but Heidemarie felt a strange sense of relief.

Her companions were by her side.

Young Heidemarie

Chloe, I...

Chloe

Shh.

Chloe cut off Heidemarie and picked something up from the ground.

Chloe

Heidemarie, take this.

It was a Life Core.

Chloe

...With this, one person can return.

Heidemarie, you go back first.

Young Heidemarie

What...?

Chloe

You're a mess. How did you even make it this far in that state?

Chloe said as she brushed back Heidemarie's hair.

Chloe

Go back first. I'll follow right behind you.

Young Heidemarie

H-how...?!

Chloe

Only one Protos wasn't deployed for this operation, right?

I sent a support request, so we just need to hold out until another Protos arrives.

Everyone's together, so we'll be fine.

Looking around, the Agents whose eyes met hers nodded.

SS Edenity Agent

Heidemarie, go back first.

We promised, didn't we? That you'd rest once you reached Protos.

Young Heidemarie

B-but... there are still so many monsters...!

Chloe

So, would you be of any help if you stayed?

Young Heidemarie

...What?

Heidemarie

(No, no.)

Chloe

You'd just be a burden.

Heidemarie

(I can be helpful.)

(That's what... I should have said...)

Those words weighed heavily on Heidemarie's chest.

Chloe

I'll... I'll catch up.

Young Heidemarie

......

...Chloe, *sob*... actually, there's something I need to tell you.

Heidemarie mustered her last bit of courage and told Chloe about their companions' situation.

Chloe's expression hardened for a moment.

Chloe

...Everyone?

Young Heidemarie

I'm sorry... if only I... if only I had done better...

After a moment of silence, Chloe pressed the Life Core into Heidemarie's hands.

Chloe

I understand. I've heard.

Young Heidemarie

Chloe...! You'll really... *sob*, you'll really come back, right?

Chloe

...Do you remember the promise I made?

Chloe's promise that she would never die in front of her.

Heidemarie nodded.

Chloe

That's enough.

Chloe contacted the Protos mother ship. The Life Core began to respond.

In her fading vision, Heidemarie's eyes fell upon Chloe.

Chloe

See you again, Mari.

Chloe smiled.

Ellinad Second Pioneer Base Indoors

SS Edenity Officer

The operation's results match what's written in the report.

...Agent Heidemarie, you truly did well.

Everyone will praise you as the hero of this disaster.

The report was filled with details of the personnel Heidemarie had rescued.

A record showing the rescue of over a hundred civilians trapped inside the Chaos, and the elimination of dozens of monsters including high-risk entities in the process.

SS Edenity Officer

You saved someone's father and mother, someone's precious child. You should be proud.

It was an overwhelming achievement for a student agent to accomplish.

However, Heidemarie's eyes were fixed on one spot.

At the bottom of the document, written in small letters.

[Deceased - Agents] [...... Mev/Khalia/Evie/Chloe - Bodies unrecoverable]

Water droplets fell onto the report.

Young Heidemarie

...Liar.

...Chloe... *sob*... you liar...

Heidemarie clutched the report and began to cry out loud.

Heidemarie placed her hand on Chloe's grave.

Heidemarie

If only I hadn't gone.

If only Chloe had used that Life Core.

If only I hadn't shaken Chloe with the others' stories.

If only we had promised not to die before each other, rather than not dying in front of me...

......

Chloe... do you regret bringing me onto the team? Or......

The Day of Reunion

Before the graves of her companions

Heidemarie

Everyone, I'm here.

You know what? I became the Mayor of the SS Edenity.

I'm not sure why, to be honest.

They say there's no one on the SS Edenity who cares about the citizens as much as I do, or something like that.

...When in truth, I'm not in any position to be here.

Heidemarie spoke as she pulled out weeds growing around Khalia's tombstone.

Heidemarie

Khalia, you would have certainly been a much better role model to everyone than someone like me.

With your dignified appearance, you would have had so many fans.

I'm so clumsy and show my foolish side too often.

Heidemarie brushed off the pollen that had accumulated on Evie's tombstone.

Heidemarie

Evie, I want to be a source of strength to everyone like you were.

To make people smile even when they're sad, to keep the atmosphere fun.

It's not as easy as it sounds. I just end up making things awkward all the time.

Heidemarie smiled as she looked at Mev's tombstone.

Heidemarie

Mev. When will I become as dependable as you?

I became Mayor, but the distrust toward me never ends.

No matter how high a position I reach, I can't hide my true nature.

If it were you, Mev, that wouldn't have happened.

And...

...Chloe.

......

Heidemarie pressed her forehead against the grave and whispered.

Heidemarie

...I miss you, Chloe.

......

Every time I close my eyes, the nightmare of that day returns.

She looked at her companions.

Heidemarie

Everyone, do you still resent me?

I keep trying my best to atone to all of you...

It's still not enough, is it?

Of course not. If only I had been a little more competent.

If only I had been more like all of you, maybe no one would have left my side.

Because I was lacking... everyone...

......

...Still, I'll continue this act just a little longer.

Mayor, hero... titles that don't suit me at all.

But all of you would have surely worked hard for the SS Edenity from any position.

If it's work you would have done, then it's now a burden I must carry. Because I'm the one who survived in your place.

I'll keep trying my best. I'll keep staying strong.

...So, when we meet again.

When I... when I reunite with you all before long.

Please, forgive me just a little then.

Before she knew it, tears were streaming down Heidemarie's cheeks.

Heidemarie

I'm sorry... I'm truly sorry...

Everyone... I'm so sorry.

Waiting for a forgiveness that would never come, Heidemarie remained before her companions' graves for a long while.
