In a World Where Chastity is Reversed, I Ended Up Working as a Hot Spring Attendant - Chapter 83-84

Chapter 83: Day 1 – on the Coastal Road (Tsubame’s Perspective)

In this world, having half-sisters is quite common. With a 1/100 male-to-female ratio, it’s not unusual for a single father to have 100 children. This is a given.

Generally, genetic testing isn’t emphasized after the fact; knowing from the start is what matters. The sperm used with government-backed pregnancy and childbirth assistance is usually selected blindly and randomly to prevent inbreeding and maintain genetic diversity. The producers of the sperm remain anonymous. Occasionally, foreign sperm is used, so sometimes there are girls who don’t look typically Japanese.

Therefore, the half-sibling issue only arises when the father acknowledges and claims the child as his own.

This often happens in small, harem-like communities, resulting in very close-knit sisterly relationships.

Our genetic father is a man called Kohaku Umino, a legendary helper known to have 2,000 recognized children through direct insemination.

He had a hobby of birdwatching, so our names are all bird-related. When we introduce ourselves, it’s usually obvious who our father is—whether that’s good or bad.

Sadly, he has passed away, so there will be no more additions.

Beep

While driving around, I spotted a very familiar face and honked the horn softly, calling out.

“What are you doing, Misago?”

I got out of the car and approached her in a casual, flirtatious manner, as usual.

“Giving directions. If you’re going to be a nuisance, leave…”

Her tone was full of annoyance.

“Oh, is that hostility?”

I played it up as usual. She might have some intensity, but it’s nothing compared to the cuteness of a younger sister. Although we’re in the same grade, there’s enough of a difference in maturity in six months.

“Sorry, but I’m on a date right now, so maybe another time?”

A low voice I didn’t recognize made me blink.

“What…?”

Both Misago and I voiced our surprise in unison. This is where our sisterly connection shows—we’re annoyingly similar in some ways.

I looked for the source of the voice and found a small boy in a white yukata hiding behind Misago. A boy? Really?!

I did a double-take.

“Did I surprise you?”

The boy’s voice had a hint of mischief and a mature tone that seemed odd for a child.

Meanwhile, Misago blushed deeply in response to his words. My sister is so innocent.

“Where did you find him, Misago?!”

I shouted out loud on the coastal road. I wasn’t angry—Misago wasn’t startled, proving that.

What had happened was, while out on an errand, I saw Misago, stopped the car, and struck up a conversation. Suddenly, she had a boy with her, holding hands.

The boy even said they were on a date. My same-age half-sister on a date.

Of course, I’d shout.

“I found him over there.”

She made a shushing gesture and pointed to the beach below the cliff.

Looking down, I saw the rough waves crashing against the rocks, making a rattling sound as they washed the shore—a local feature known for its deadly history.

“Can we call it an emergency evacuation?”

Misago looked troubled. The situation was too mysterious.

“Not really my responsibility?”

As a lower-level government employee, my job is mostly miscellaneous tasks.

Today, I was out running errands, dealing with vacant houses due to severe depopulation.

Misago bringing along a boy might be a job for the police.

“I’ll tell anyone who asks that it doesn’t seem like a criminal matter.”

At my words, Misago’s face brightened.

“Thanks.”

“Just remember to share any benefits.”

I replied lightly, waving my hand and indicating my stomach area.

“Fine, if things go well.”

Misago smiled wryly and whispered.

That was how I met Hisui-san on this very day.

Chapter 84: Day 2 – Marriage Registration and Commemorative Photo (Right Before Going to the Hospital) (Tsubame’s Perspective)

“Good morning. How can I help you today?”

Seeing familiar faces at the entrance, I called out to them first.

It was Misago and Hisui-san, whom I saw yesterday, along with the rare sight of Hachikuma, who had recently returned after transferring from a Self-Defense Officer to a Security Officer. It had been a while since I last saw her, so it was nostalgic.

“Please process these,” they said, handing over the marriage registration form and national ID cards for three people plus one.

“Oh, congratulations…”

I reflexively started to respond, but then did a double take at the documents and the people in front of me.

“Wait, what?”

I couldn’t help but double-check the papers and the group.

“Isn’t this a bit fast?” I muttered to Misago.

“It might be fast, but my grandmother always said that these things need to be decided quickly. Otherwise, you lose out and it becomes a hassle later on.”

“Yeah, I get that. There will definitely be all sorts of meddling.”

I nodded seriously, not specifying who might interfere.

“Please wait a moment.”

I excused myself lightly, signaled to my colleagues that I would handle this, and took over the entrance duties.

The names and IDs were all correct.

I scanned the documents, ID cards, and vein authentication on the readers. There were no signs of fraud. Hisui-san’s ID had no logs, which was odd, but since there were no errors, it seemed legitimate. Hachikuma’s ID was also linked, so it wasn’t my place to question it.

To make it easy to identify, the system assigns a matching background color to the IDs of security officers and their charges. The displayed color was a translucent white-green, the color of jade.

Their income records showed millions, indicating they would refuse government subsidies and interference. I understood.

The presence of Grandmother Yata as a guarantor was overwhelming.

Legally, there’s no income requirement to get married, but low income can invite government interference under the guise of support. They might dictate where you live or connect you with influential people.

Internally, I marveled at Grandmother Yata’s thorough preparations while processing the paperwork.

As a government official, I can read various details from ID cards and numbers, but confidentiality rules prevent me from disclosing any of it.

“With that, the process is complete. Congratulations.”

I stamped the documents with a casual tone, befitting the familiarity.

Despite digital advancements, some parts of the process remain analog.

I handed the copies back to Misago and the others.

“Shall we take a commemorative photo?”

“What for?” Misago tilted her head.

“To post it prominently on the notice board at the counter!”

I pointed energetically to the currently barren notice board.

It was filled with vacant house listings and job vacancies due to depopulation.

“Good news should be celebrated by everyone.”

I grinned exaggeratedly.

I wanted to brighten the gloomy atmosphere of this area.

No one could oppose this idea here, especially given the influential people involved.

We took a commemorative photo with the three of them awkwardly smiling.

It’s great having a boy around. He brings a certain charm.

Before I knew it, all the staff joined in for a photo session, and we also took some pictures together.

I felt a deep joy for Misago and her happiness.

Unexpectedly, my own eyes welled up.

Why am I crying too?

Everyone else was feeling the same; even though Misago is the youngest sister, we should be smiling more.

“So, maybe share some of your luck with me, like seeds or something?”

I teased Misago lightly.

“So, did you do it?”

I leaned in and whispered in her ear.

“Yeah, perfectly,” she said, blushing and patting her belly.

I was genuinely happy for her.

Later, the whole community brought gifts to see Hisui-san, turning it into a big celebration. I felt a bit guilty about it.

~Postscript

I’m a bit older than Misago, though we are in the same grade. Suzume is one grade above, and Misago is 170 cm tall, while I’m 160 cm.

Misago is the youngest sister, being the last child born directly. That’s why everyone dotes on her, despite her being an ultimate virgin but quite spirited, which boosted her self-esteem.

There are many other half-siblings with the same father but different mothers. Most of the staff are like family, making it an at-home workplace for the bird group. I, the 20-year-old newbie, have quite a big attitude due to this. That’s why I was doing the lower-level tasks like fieldwork along the coast.
