"Hey, Serika-chan. Now I'll be able to be with Hii-chan again."

Saying this while staring intently at the geometric pattern writhing on her palm, Nanami-senpai.

Her eyes were soaked with passion, radiating something far more intense than the gentle feelings of a lovesick girl.

Having just watched her brother's video, she probably thinks she can reclaim him from those women.

Still, I don't think she's that foolish...

Maybe I should bring her back down to reality a bit.

"Big sister. I know you understand, but the other world is vast, right? Meeting up with your brother might be a good final goal, but surviving day to day is more important. To be honest, you'd be better off forgetting about your brother for now."

"Forget...? Then what am I supposed to do? Just survive enough to not die over there?"

"Don't twist it like that. Then, big sister—what exactly happens if you stay like this and reunite with your brother? Will you just sit at home alone while everyone else ventures into the labyrinth? Can you really compete with someone like Rifa, the legendary beauty of the other world, or Jeanne, a model-level beauty, like that?"

"……What are you trying to say?"

A spark ignites in her sister's eyes.

It might sound harsh, but the only way to get through to Nanami-nee is to confront her directly. Otherwise, her stubbornness will prevent her from understanding.

"If you don’t grow stronger, even if you reunite with your older brother, you’ll just be slowly worn down. Your brother is kind-hearted, so he’ll surely protect you if you’re with him, right? But that’s all. The bond built through standing side by side in battle—those are the ones like Reflair and Jeanne. You, on the other hand, might end up being a difficult presence to handle. You’re not strong at all, yet you’re consumed by jealousy more than anyone else."

"Serika-chan, you—"

"Isn’t that right?"

It might be a bit too blunt.

Nanami bites her lower lip, searching for a rebuttal.

But it’s the truth.

With just a little imagination, she must have already pictured that scene herself.

…In the first place, my brother doesn't see Nanami-san—of course, nor me, nor Karen—as women.

They're certainly the closest family members.

But that's all.

He doesn't view any of us as romantic partners.

Sister must know that perfectly well.

He does perceive Reifrea-san as a woman, yet believes himself merely a childhood friend in her eyes.

The competition is already far beyond reach.

"Besides… my appearance is a complete loss. A beauty like Reifrea-san is rare—hardly ever found even if you search the entire planet."

"Ugh…! That really stings… But Hei-chan isn't the kind of guy who chooses based on looks."

"Sweet! So sweet, big sis! My brother’s totally weak to women who exude motherly warmth—maybe because he grew up without his mother’s love! He doesn’t really fall for Jeanne, but he’s already head-over-heels for Refreia… actually, I’d say it’s better to just admit defeat and plan accordingly!

The reason I and Karen have been working so hard on our bust-up exercises since childhood is because we’ve known my brother’s weakness all along.

Whether it’s thanks to our efforts or just natural inheritance, we’ve developed decently—but against Refreia’s natural charm, I don’t stand a chance.

That girl’s a weapon.

'So what should we do? Just live lonely in another world without even meeting up with Hii-chan?'

"It's not like that. I already contacted the training facility a moment ago, so for the next twenty days until the transfer, you're going to train with everything you've got. Forget completely about your old life—think of yourself as having time-traveled to the Stone Age. Otherwise... you might actually die, or suffer terribly. Since you're a young woman, you have to be ten times more careful than a man, and to do that, you ultimately have to become strong."

"I see... yeah, that makes sense. Thank you, Serika-chan."

"No, actually, I regretted not preparing myself properly when I was chosen first. I didn't really understand what interworld transfer even meant back then."

At least, it seems my sister finally understands.

To transfer to another world just hoping to reunite with my brother would inevitably lead to a miserable fate.

That god is fundamentally fair. Yet, three hundred people have died in just one month.

A fair number of them have gone insane.

It's cruelly equal—perhaps you could even call it innocent.

Either way, I don't want my sister to end up like that.

"…………Selica-chan. But you know, I've already died once. So dying doesn't really scare me much."

Maybe she still doesn't understand.

My truly hopeless sister.

"You should be afraid. Be afraid—for me, for Karen."

"Mmm. Such troublesome little sisters…"

Swallowing those words meant for me, I sent another email to the private military company.

She'll need to train both her body and her mind.

Could she kill an animal? I'll have her go through a program, but it'll probably be difficult. She really likes animals, after all...

Still, whether she can do that or not will make a big difference in how easily she survives in the other world. After all, humans live by killing and consuming other creatures.

In that world, where spirit power exists, it's even more important.

"By the way, about what we're taking over there—this one thing, I'm going to decide for myself, sister."

"Eh, really? What about the photos?"

"You can retrieve them when you reunite with your brother. He'll definitely keep them, so don't worry."

"That's true..."

As I typed an email to a major firearms company in Connecticut, I was thinking about the equipment my sister would be taking with her.

The company I emailed is headquartered nearby where we live and is the world's most famous manufacturer of carbine rifles. They'd be the ideal choice for commissioning a custom firearm.

God allows carrying a single item that can be held in one hand.

If it's a firearm, accessories like scopes and magazines are naturally permitted, and even add-on grenade launchers are acceptable. However, forcibly attaching extra magazines is not allowed. The key point is that it must remain a single, unified tool. The balance is a bit tricky, but modifying the magazine to be unusually large for a custom piece should be fine.

A standalone firearm typically doesn't carry many rounds. Even a standard assault rifle usually holds around thirty rounds at most. Since ammunition can't be replenished in the other world, bullets become the most critical resource.

In short, conditions like "more ammunition," "greater power per shot," "reliable performance," and "easy to handle even for women" come into play. Maybe a gun that fires slightly larger rounds than standard would be better.

Well, in any case, my knowledge in this field is only at a common-sense level.

Time is short, but if I just throw money at it, they could probably make a custom firearm right away. Probably.

Just as I finished typing the email, the phone rang sharply—Karin calling.

Another problem must have come up again.

"…Serican, you saw it!?"

"What? Wait—oh right. It's been updated already?"

"It's updated, so look at it…"

I immediately understood what Karin was trying to say.

The list of people transferred to the other world had been updated.

This transfer involved 300 individuals.

Considering the world population has surpassed seven billion, three hundred people is truly a small number.

The chance of someone you know being selected—

"Wait, you were the one chosen!?"

Come to think of it, I never considered the possibility of Karen being selected.

I assumed neither of us had been picked—

"No, that's not it. Hurry up. You'll see when you look."

"S-so, don't scare me like that..."

While talking, I operated the tablet.

And immediately, I understood why Karen let out a voice like she was dying.

"G-God... you did it..."

"Why... why would something like this happen...?"

"—Maybe I believed that message after all..."

I sent a fake message pretending to be God through LINE when summoning that man.

"I am god. I've seen your desire to go to another world. I'll prioritize guiding you to the next one. ...But that was a mistake. If you continue like this, you'll be arrested by the police and sentenced to death. I've ordered my subordinates to hide you. They'll arrive shortly, so go outside with the blood-stained clothes and the knife used in the crime."

"Leave a note for your family saying you're on a training journey to another world. There's a need to gather some energy before the next transfer, so it will take time."

"Leave your smartphone behind—it might be traced by the police. We'll provide another device here."

That's what it should have said.

And we haven't bothered to explain to you each time that this was a fake email.

If... that man had continued believing that content was 'real,' and had solely dreamed of being transported to another world, convinced that no matter what circumstances he faced, he would eventually make it there— if he had clung to that dream as his only source of strength, even when suffering greatly— then... "Is this also my mistake?" A serious-faced, chestnut-haired boy appeared on the screen. Transfer Candidate No. 1133, OZAWA YUICHI. The man who had killed Nanami-sister and her family, and had once taken my brother's life, had been chosen as a world transfer candidate.
