Chapter 9: Obligation

“First, the purpose is to address the declining birthrate and prevent the gender imbalance from worsening. It also serves to provide sperm to women who have no opportunities to meet men, including families of women only. Is everything clear up to this point?”

“Yes.”

It still feels unreal.

Declining birthrate, reversed chastity world, gender imbalance…

“This procedure is carried out only at large hospitals with specialized facilities.”

I see.

“We also take the highest possible measures to ensure safety. The area used is restricted so that general patients cannot enter, and even staff are prohibited from entering while the procedure is in progress. Two guards are stationed at the entrance at all times, and entry requires biometric authorization. Security is airtight.”

“They even have authorization to open fire on intruders.”

“Correct.”

“I’m very good with firearms too.”

“You can just shoot that easily…?”

“If a man’s safety is threatened or the collected sperm is stolen, that is the worst-case scenario for the extraction department. Most judgment calls are left to the guards on-site.”

Her serious tone matched the seriousness of the situation.

“Well, that makes sense. If a crime happened while someone is defenseless…”

“Yes. If that happened, no man would agree to provide anymore. That is why security is even stricter than a prison or a bank.”

Much more extreme than I expected.

“Basically, you will enter the room alone and provide it yourself.”

That makes sense for safety. I nodded.

“After the extraction, strict security continues. The collected sperm is immediately transported to a designated cryogenic storage room, which also requires biometric authentication to enter.”

“It’s like something out of a spy movie.”

That was the impression I got.

“There was a case where an employee tried to steal extracted sperm.”

“Ah, I remember that being in the news.”

“So things like that really happen.”

“Yes. You could call it… a woman’s nature. In any case, because of that incident, security was reinforced.”

“And now, regarding compensation.”

Tachibana flipped to the next page and showed it to me.

Finally.

“This is the part I was most curious about.”

“Really?”

Haruka asked.

“Yeah. I’m living off money borrowed from the police right now. I need an income. And when I tried to look for a job, everyone stopped me.”

Seriously, everyone desperately stopped me.

“First, the basic compensation is 500,000 yen per extraction. Additionally, bonuses are given if the sperm quality is high.”

“Quality?”

“Yes. For example, a high motility rate or favorable genetic traits. Also, those who provide regularly receive additional bonuses.”

“Ho… bonuses.”

“However, there are certain requirements. You will undergo a medical examination and psychological evaluation beforehand. Depending on the results, you may not be eligible.”

Tachibana added with a small smile.

“Well, it’s rare to be rejected.”

“That should be all of the explanation. Do you have any questions?”

“After I provide it… is there anything I need to do?”

“No, nothing. Your involvement ends after the extraction. Everything after that is handled by the institution.”

“I see.”

“Any other questions?”

“No, I’m fine.”

“Understood. Then please sign these documents so we can proceed.”

She handed me the form labeled Application.

I reviewed it carefully and signed.

“All preparations are now complete. Good work.”

“Ahh, I’m exhausted!”

I stretched my arms overhead to loosen my shoulders.

Once I lowered my arms, I noticed the three of them were red-faced.

…Huh? Why is everyone blushing?

“What’s wrong?”

“You really don’t have any sense of caution, do you?”

“Yes, this is beyond excuses.”

“I agree.”

They’re having their own conversation.

That’s sad, okay?

What are they talking about?

“Um… what are you talking about?”

“To think you weren’t wearing an undershirt.”

Haruka said, sounding genuinely shocked.

Undershirt? Ah, right, I didn’t wear one today…

“I only have one, and it’s in the wash. But does it really matter if I’m not wearing one?”

I really didn’t understand.

Maybe my shirt rode up when I stretched and exposed my stomach?

…Wait.

Or could it be… the cultural value of clothing is reversed too?

That idea flashed through my mind.

How to confirm it…

“To wear only a T-shirt with nothing under it… are you trying to tempt me?”

Yep.

Confirmed.

Haruka’s eyes were sparkling.

“Yes. Like I’ve said before, women are beasts.”

“Well, if you’re okay with being attacked, then sure, go ahead and stay like that.”

“No, I wouldn’t want that… probably.”

“See? That’s exactly the problem. You don’t say no clearly.”

Tachibana sounded tired.

Well, when everyone you meet is beautiful…

If it’s someone I know, I’d say yes…

I won’t say that out loud though.

“For now, we’ll leave that to Haruka. That concludes today’s meeting. Thank you for coming.”

Oh, it’s over!

“Regarding the extraction, it must be done when you’re in optimal condition, so it will be scheduled after you meet with Hiiragi. You’ll be contacted later.”

Yamaguchi explained the timing.

“Got it!”

“Then for the return trip, Haruka will escort you. We’ll take our leave now.”

“What, I don’t get to drive him anymore…?”

Yamaguchi looked devastated.

“Of course not. We only escorted him because he had no guard officer. Now that he does, there is no need.”

“Yeah… I know but still…”

Haruka smiled slightly and delivered a finishing blow.

“Your job here is done. Leave the rest to me.”

So this is a woman’s battle…

Soon after, Yamaguchi was dragged away by Tachibana.

“Now then, let’s go home.”

Haruka smiled softly.

“There’s a dedicated car. We’ll head to the parking area.”

“Okay.”

◆◆◆

 

In the car.

I was told not to sit in the passenger seat because it stands out, so I’m sitting in the back.

I checked my phone and saw a message from Tachibana.

It seems Hiiragi will be coming to my house tomorrow.

“Kokuryuu-san.”

“Mm? What is it?”

“It looks like Hiiragi-san will be coming tomorrow.”

“Oh, I see. Understood. And also… I’d like you to call me Haruka or at least don’t use my surname with honorifics.“

She added, “You are my employer, after all.”

“…Alright. Haruka-san.”

In the rearview mirror, Haruka smiled in satisfaction.

“That will do. You called me by name, so I’ll accept it.”

I looked out the window.

The night scenery was beautiful.

After a moment, a question came to mind.

“By the way, Haruka-san, are you going to commute to my house every day?”

“No? I’m going to live with you.”

She said it like it was completely obvious.

“Eh… EHHHHHHHHHH!?”
