I Thought It Was a World Where Chastity Norms Were Reversed, But It Turns Out I Was Just Surrounded by the Overly Intense Girls in My Class - Chapter 14: My Big Sister’s Sense of Chastity Is the Most Broken One

Chapter 14: My Big Sister’s Sense of Chastity Is the Most Broken One

“…I went through hell.”

When I stepped out of school, the sky had already turned a deep orange from the sunset.

“We did break up the club for the day, at least…”

The yankees’ visit had barely ended before practice was called off.

After that, Yukimi and Kagurazaka Kana hardly spoke a word to each other. They got dressed without even looking at one another and practically fled the clubroom.

Nothing actually happened to me, so personally I was relieved, but the root problem still wasn’t solved.

The clubroom key aside, Yukimi is still holding onto my necktie.

“More than that, the real shock is that I didn’t get to play a single game of shogi…”

I muttered to myself on the way home.

In the end, no club members showed up, I never touched a board, and I got attacked by girls. What a disaster.

Will the day ever come when I can finally play shogi with them?

I have no idea. But at this rate, it’s hard to imagine.

“Sigh…”

I let out a long breath and dragged myself home.

“Welcome home, Tatsuya-kun.”

The moment I opened the front door, Big Sis was waiting for me in the entryway.

Pink hair tied back, wearing an apron. She’s a full head taller than me, with long, model-like limbs.

She’s a brand-new university freshman this year, yet she’s always home to see me off in the morning and greet me when I get back.

You’d almost doubt she actually goes to classes.

And she can’t cook to save her life—so bad that Mom literally banned her from the kitchen.

Yet for some reason she was wearing an apron today. It felt completely out of place.

“Why the apron?”

“For the vibe!”

I had no idea what she meant, but I’ve long since stopped trying to understand anything Big Sis says, so I let it slide.

“Tatsuya-kun, did something happen? You look exhausted.”

She peered at my face with worry while I washed up at the sink.

“Just… some stuff at club.”

“You started the shogi club, right?”

“Yeah. And it’s been kind of a mess…”

As I headed to my room she naturally followed. The second I sat on the bed she plopped down right beside me and leaned in close.

Then she pressed her face to my neck and sniffed.

“Were girls involved?”

“How did you—”

“Because I can smell another girl on you. A girl who isn’t your big sister.”

She put her hands on my shoulders and stared at me from inches away.

“Are you going through hell because of girls?”

“It’s less the shogi club and more the girls in my class…”

“Tell me everything.”

“That’s kind of…”

There’s no way I could explain that I suggested we play shogi, two classmates immediately stripped and started fighting, and then yankees burst in and saved me.

Why is a single day turning into this much of a nightmare?

This world is insane.

“Come on, tell me, tell me! Tatsuya-kun.”

“It honestly makes no sense. You probably wouldn’t even believe me.”

“But you’re suffering, right? You should let your big sister help.”

“…Fine.”

Worn down by her barrage of questions, I gave in and told her everything that happened today.

That I only want to play shogi, yet girls keep coming on to me.

That two of them started battling each other.

That the yankees ended up rescuing me.

When I finished, Big Sis openly pouted.

“Hmm… So lately you haven’t been spoiling your big sister at all because you’re too busy with the girls in your class.”

The moment she said it she scooted closer.

The instant she grabbed both my shoulders I was enveloped in something soft—

“…Huh?”

And immediately found myself pushed down onto the bed.

“I told you, didn’t I? Girls are dangerous.”

“They are, but that’s not the issue right now!”

If anything, the dangerous one here is you, Big Sis.

You’ve pinned me to the bed and you’re straddling me.

“Tatsuya-kun, I’ve said it over and over: girls are dangerous. They fall for you instantly, and the moment you’re alone they attack.”

“That description fits you perfectly!”

“Nope. I’m holding back because I’m your big sister.”

“Where exactly⁉︎”

She puffed out her cheeks in a sulky way.

Her breath brushed my cheek and sent little ticklish shivers across my skin.

This is exactly why Big Sis is impossible.

There are plenty of people in this world with broken ideas about chastity—Yukimi, Kagurazaka Kana, and others—but personally I think Big Sis is the most broken of all.

Ever since I was born she’s apparently never left my side, treating me like an extension of herself.

That warped sense of distance hasn’t changed even now that she’s in university.

She sneaks into my room every day, gives me lap pillows, and frequently pins me down like this.

No matter how you slice it, in a world where chastity norms are reversed, this is way beyond normal.

Because right now our noses are practically touching while she whispers sweet nothings.

“How about your big sister teaches you instead?”

“Teaches me shogi?”

“I have zero interest in shogi. The only thing I care about is Tatsuya-kun.”

With that she buried her face in my chest.

“You smell like another girl.”

Maybe the scent bothered her, because she pinned my shoulders hard and rubbed her cheeks against me again and again.

As if trying to erase every trace of the other girls from school.

As if overwriting me with her own scent.

She nuzzled intensely.

This is bad.

When Big Sis is in a bad mood she gets unbelievably clingy.

It wouldn’t be strange if she kept this up all night.

“Tatsuya-kun⁉︎”

I reflexively twisted my body free and bolted from the room.

“Why are you running away⁉︎”

“Because you’re attacking me!”

I heard her voice behind me but didn’t look back, just dashed out of the house.

I ran full speed into the cold night air.

※

“…I went through hell.”

Utterly worn out, I collapsed onto a bench in the nearby park.

Getting my chastity threatened at school and then again at home—this has truly been the worst day ever.

What exactly did I do to deserve this?

All I think about is shogi.

“Big brother!”

While I was busy pitying myself, I heard a voice from the slide area.

When I looked over, a brother and sister were happily playing tag.

“Big brother, why were you talking to another woman at school?”

“I couldn’t help it, okay? It was part of class.”

“Even if it was class I won’t allow it.”

“You can’t just stay silent the whole group discussion!”

“There are people at my school who never speak during discussion time.”

“That’s because they’re shy!”

“Anyway, unforgivable things are unforgivable. I really should have kept you locked up after all.”

“If you lock me up I won’t have enough attendance days!”

It sounded like innocent tag at first.

But in a world where chastity norms are reversed, nothing is that wholesome.

The sister chasing him looked like a middle schooler; the brother was probably in high school.

In other words, they weren’t little kids, and the scene wasn’t cute in the slightest.

Right in front of me, a pair of siblings in the middle of puberty were playing tag in the park—an utterly bizarre sight.

“…Huh?”

The brother’s uniform looked familiar.

Specifically, it was the same as my high school’s.

Wait—isn’t that Wakabayashi from my class?

His expression was so different from in the classroom that I wasn’t completely sure, but it felt like him.

He’s got it rough too, huh.

Me getting attacked by my big sister, him facing potential confinement by his little sister.

Looks like we’re in the same boat. I was feeling a random sense of camaraderie when—

“We’re going home now, big brother.”

“You mean ‘going to lock me up,’ right?”

“Don’t worry, I’ll make sure your attendance record stays perfect.”

“I’m not trusting that at all!”

Well, at least my situation probably isn’t that extreme.

I get attacked a lot, but I’ve never actually been confined.

Seriously though, confinement?

That’s straight-up a crime.

Thinking that, I stood up and stepped out of the park.

At that moment a night breeze blew past, gently lifting my hair.

The pleasant scent of the sea tickled my nose and reminded me I lived near the coast.

The land, the town, the values—everything is different from my previous life.

But the biggest difference by far is the concept of chastity.

“This world really does have reversed ideas about chastity.”

There’s no denying it.

Yukimi, Kagurazaka Kana, and Big Sis—

The only way to explain their words and actions is that chastity norms are completely flipped.

Even so, I’m going to keep living in this world.

In this ridiculous world where chastity is reversed.
