When We Found Out We're Not Blood-Related, My Little Sister Became Seriously Love-Brained ~When a Little Sister Stops Being a Little Sister, the Ultimate Heroine Emerges!~

Chapter 10: Fetish Little Sister Appears in the Bath

—Morning changing room.

Squeak.

When I turned off the shower and opened the bathroom folding door, Suzune was there.

“…I like this smell.”

Suzune was pinching the sleeve of my hoodie and bringing her nose close.

Our eyes suddenly met.

Suzune’s gaze wandered unsteadily, and she swept up her bangs. Her left earlobe, briefly visible, was red.

“I-It’s not like… I just had business here… that’s all.”

“You’ll be late.”

I heard Mom’s voice.

“Mooom! I’m coming!”

Suzune left the changing room as if nothing had happened.

The lingering citrus scent drifted.

Scent and memory are connected—the warmth of Suzune from last night revived in my head.

※

6:00 AM

“Good morningg. Fwaaah~”

When I came out of my room, Suzune called out to me.

Suzune is in fluffy loungewear with her hair tied up in a scrunchie.

A morning no different from usual.

It seems I’m the only one feeling flustered, which is embarrassing.

※

“Suzune.”

I want to praise and nurture this girl in front of me who lacks confidence. But suddenly doing that in the morning would probably put her off.

“What?”

She responded naturally.

“C-cu-… never mind.”

Even though it’s right at my throat, the word “cute” won’t come out.

I patted Suzune’s head to cover my embarrassment.

“Mmm. Do it more.”

Then Suzune rubbed against me like a cat.

She’s happy with just this?

Then I’ll give her head pats every day.

Next time I’ll work hard so I can say “cute” too.

※

Sliding closer, Suzune brought her nose near my chest area.

“Ow!”

When I flicked her forehead, Suzune covered her forehead with both hands. She’s pursing her lips with a dissatisfied face.

“What are you trying to smartly sniff?”

“Because. I like your smell. It’s the start of the day.”

The start of the day—this isn’t a forest bath. As usual, Suzune is honest with her desires.

But if the quality of smell is relative evaluation, using Suzune as the standard, most men in the world would be smelly.

“I just woke up, so I smell like sweat.”

When I said that, Suzune sniffed.

“No, that’s good in its own way. I mean, if it’s yours, Yuuma, I actually prefer it around that level…”

Even as my little sister, she’s quite the fetishist.

“You should hide that kind of thing a bit.”

Suzune put her arms on her hips.

“What’s wrong with it? Your smell is part of you. It’s natural I like it. If you say it like that, it’s like I’m some kind of pervert. Fine, I’ll endure it, so give me your underwear instead.”

No, you actually are a pervert.

Does this girl not know the phrase “shelving herself”?

“Then will you give me your underwear in exchange?”

Then Suzune glared at me.

“Die. Pervert!”

Too unreasonable.

“You…”

I made eye contact with Suzune.

Thump.

Oh no. My heart is racing. My face is getting hot.

But Suzune’s face was even redder.

“I-I’m not forcing you… but. Oh no. I need to redo my hair. Mooom. Do you have my uniform?”

Suzune ran down the stairs.

“Right. School starts today.”

Well then.

I should brush my teeth too.

※

Suzune insists she doesn’t remember anything from that night.

Well, fine.

If that’s the case, ignoring it is an older brother’s kindness.

I’m glad our parents came home that day.

Far from protecting Suzune, I almost hurt her.

Suzune’s slightly fetishistic side was unexpected, but I don’t dislike that she’s interested in me.

“Even though we’ve been siblings all this time, there are still sides I don’t know.”

I looked at the clock.

I should get ready soon.

Suzune has club activities, so she leaves home early.

Our high school has blazers for both boys and girls, but even from my perspective as her brother, the uniform suits Suzune well. So it’s unfortunate I can’t see it.

When I entered the changing room to shower, heat still remained in the bathroom.

“Did Suzune just get out?”

When I looked at the laundry basket, black panties were carelessly placed there. Suzune’s.

…Is this girl planning to put those in the laundry normally!?

Too brave.

If Mom sees those, she’ll probably misunderstand that Suzune has a boyfriend, right?

Suzune has had surprisingly careless aspects since childhood.

※

That said, I can’t hide them or wash them for her. I reluctantly decided to leave them as is.

As I was washing my hair, someone entered the changing room. Who is it?

“Mom?”

“…It’s me.”

Suzune. Apparently she’s still home.

She’s rummaging through the laundry basket.

“Hey, I’m showering though.”

I opened the folding door and stuck just my head out.

Then I made eye contact with Suzune in her uniform.

Suzune glanced at around my neck for a moment, then looked away.

My hoodie fell from Suzune’s fingertips.

“It’s fine, right? I just forgot something. Oh, I have club today so I’m leaving first!! See you at school.”

Suzune threw a bath towel at me.

“Mooom. I’m leaving now~”

Saying that, she hurriedly left.

…Or so I thought, but she came back.

“I properly like you, that’s all!”

Saying that, the door slammed shut. This time she really left.

※

What’s with that girl?

I feel like confessions are supposed to be done at decisive moments. But since that day when she ran away and we made up, she tells me almost every day.

Well, that’s nice in its own way though.

When I got out of the bath, Suzune’s panties were gone. Did she come to retrieve those?

Somehow, since that incident the other day, I feel like I’m being strangely conscious of. Is that girl giving up pretenses?

Her smell fetish is completely exposed too.

Well, but.

I’m glad I got to see Suzune in her uniform.

※

I ate breakfast and put on my uniform.

How should I say this? I have incredibly zero motivation.

At the closing ceremony, the homeroom teacher said “let’s refresh and work hard from second semester,” but because I refreshed, my motivation disappeared instead.

Why is that?

I actually understand.

When school starts, my time alone with Suzune will end, and Suzune might be looked at strangely by the people around her because of me.

…I’m anxious that Suzune might be troubled because of me.

※

The morning news program is playing on TV.

If I don’t leave before this ends, I won’t make the train.

I should eat breakfast and leave soon.

Breakfast is fried eggs with bacon and sausages. Toast and salad. Maybe because it’s a new semester? It feels a bit luxurious.

I feel silent pressure from this luxury.

“Too lazy to go” probably won’t work.

As I was spacing out drinking coffee after the meal, Mom called out to me.

“Yuuma, is it okay to be leisurely?”

“It’s fine. Unlike Suzune, I don’t have club activities.”

Mom said while cleaning up the dishes.

“Yuuma, are you not doing… club activities anymore? You were strong, so it’s a waste. Even Suzune…”

I know.

I did karate since I was a kid. But various things happened and I quit in my third year of middle school. Suzune often came to cheer, so I think she was disappointed when I quit.

That’s why Suzune said I was “too lame” when I didn’t fight back when protecting her at the park after she ran away.

“I’ll leave soon.”

When I stood up, Mom stopped me.

“This.”

Mom handed me a drawstring bag.

A bento?

“That’s unusual.”

When I said that, Mom grinned.

What? That’s meaningful.

“Suzune said to give you this. You two really made up. I’m glad.”

Suzune’s handmade?

Is she telling me to bring dark matter to school?

If it’s too terrible, I can eat alone on the rooftop.

I went back to my room and looked inside the drawstring bag—there were two rice balls, a boiled egg, marshmallows, and a memo. The rice balls were normal.

“I made these. I’m not good at it yet, so sorry it’s just rice balls. Want to have lunch together? I’m looking forward to seeing you. Let’s work hard at school together. Don’t skip, okay? Suzune”

What is this?

It’s like a couple who just started dating.

Oh no.

My little sister is too cute.

※

Somehow I’m getting courage.

Should I put some spirit into it and go to school!

I shouted while putting on my shoes at the entrance.

“Mom, I’m leaving!”

※

—The tower leading to the rooftop.

A small memo at the bottom of the bento wrapping.

“We had an indirect kiss… didn’t we?”

When I looked up, Suzune’s gaze stopped.

Ding-dong. The start-of-class chime.

“Abyss Eye” announces the new semester.

T/N: Dem I kinda like this fluff.

Chapter 11: “Abyss Eye” Peers into True Feelings

The wind blows through.

Suzune held down her hair as it flew up.

Lunchtime on the rooftop.

A lunch for just the two of us.

Tomorrow and the day after, an unchanging scenery.

Suzune said:

“Tomorrow at lunch, I have first dibs.”

※

8:45 AM

Private Saginotani Academy High School, Year 2, Class 3.

“Hey there.”

I looked around the classroom.

The first day after summer vacation inevitably exposes the results of summer youth whether you like it or not. In that sense, there’s no crueler vacation than summer.

That brown-haired guy over there at that seat.

He had normal black hair before, right? Something good must have happened during summer vacation.

My summer vacation this year started with my little sister running away. It was quite tough.

When I sat down, a classmate in the seat behind me spoke to me. His name is Shouta Saitou, one of my few friends.

“Hey. Shinomiya. Did you have your first experience? I seriously came so close.”

Saitou’s face isn’t bad, but his character is twisted, so he’s not popular. In a word, he has eighth-grader syndrome, does karate, claims to be an introvert but is pointlessly energetic.

In short, annoying.

Girls often call him gross.

…Yet apparently Saitou came close.

“Did you get a girlfriend?”

At my question, Saitou made a solemn face.

“No, I worked really hard at my summer job. I saved up about 50,000 yen.”

“Saved up… Ah, I get it. You showered a girl with gifts, right?”

“Completely wrong. I went to a shrine clutching that money.”

“Huh?”

I have no idea where this conversation is going.

“You’re dense. I’ve been interested in a girl lately.”

“Who?”

So spring came for Saitou too.

Well, it’s already fall though.

“Well, at the shrine… the busty one. She said she likes people with faith.”

Is his target a shrine maiden?

“You’re being evasive.”

“Well, anyway it didn’t work. She’s probably a college student. She was out of my league.”

“You still have the money, right?”

“No, I don’t at all.”

The fact that such a large sum disappeared means nothing about this is normal.

“Why?”

“To appeal my faith. Manly and boldly, I dunked the money all balled up into the offering box.”

“But it’s an offering. There’s definitely divine favor, right?”

Saitou made a face like he bit into a bitter bug.

“Rather the opposite effect. She said ‘that’s sacrilegious.'”

I knew it.

This guy is too unfortunate.

“By the way, Suzune-chan is the subject of rumors.”

Saitou shook his head and continued talking.

“What kind of rumors?”

Suzune is popular after all.

“She’s in such a good mood, people think she got a guy.”

A guy? Could it be she got a boyfriend?

…That can’t be, right?

We were together every day during summer vacation.

She told me she liked me almost every day.

She sniffed me this morning too.

So does that mean she was in a good mood because of me?

Saitou held his right hand in front of his face and somehow produced a marble and placed it on the desk.

“Wait, my abyssal Abyss Eye shows that Suzune-chan had a summer experience.”

He suddenly went into his mode.

As expected of severe eighth-grader syndrome.

Also, abyssal and abyss mean the same thing…

Is the experience referring to that chocolate night incident?

If so, it’s not entirely wrong. Fearsome abyssal Abyss Eye.

Saitou is an idiot but humanly trustworthy, so I’ll tell him about Suzune later.

“A summer experience, I think that’s probably wrong?”

“No, wait. Alice Eye is starting to shine.”

Hey hey.

Wasn’t it Abyss?

Saitou continued.

“Suzune-chan will be confessed to soon. The other party is ‘Book.’ Muoh. That evil magic society. They’ve interfered with my evil eye.”

I don’t need that, so please say it properly to the end. Stop doing things like anime that say “see you” and never get a sequel.

※

But Suzune is quite popular.

A confession is a possible story.

If so, who’s the other party?

Book doesn’t seem like a person’s name though.

A book? Could it mean book?

In our class, there’s only one person who starts with that kanji. Honda Sou. A tall, handsome guy at the center of the popular group.

Moreover, he’s on the soccer team and top in grades among boys. Worst of all, his personality is good too. That’s why he’s periodically rumored with Suzune, who’s also top in grades among girls.

But no way.

Not Suzune.

※

Saitou is looking at me.

“The abyssal Abyss Eye reacted again. Shinomiya, you got a girl you like, didn’t you? No, rather you’re being liked?”

I felt my heart skip for a moment.

Could it be about Suzune?

It’s true that my cheeks get hot when Suzune stares at me. …But she’s my little sister, right?

“Also, don’t say it in a confusing way.”

It sounds like it’s about another girl. If that jealous little sister misunderstands, who knows what will happen.

※

Ding-dong.

The start-of-class chime.

“Look. Class is starting.”

We were warned by our homeroom teacher.

When I looked at Suzune, she was glaring this way.

She’s definitely misunderstanding.

The class after a long time ended in a flash while I was sound asleep, and it became lunch break. I thought Suzune would be clingy even at school, but surprisingly, she was distant.

That’s a bit lonely in its own way.

※

I felt a gaze and looked at the classroom entrance to see Suzune there. She’s beckoning me over.

“Let’s go to the rooftop.”

Saying that, Suzune started walking.

With each step up the stairs, there was a clicking sound. Suzune stopped several times and glanced at me.

Is she still angry?

※

On the landing going up to the third floor, first-years were taking photos. Three of them taking selfies together.

Our girls’ uniforms are popular with students.

Apparently, the gold embroidery on the navy ribbon. That apparently goes viral on SNS, so I often see similar scenes.

(Suzune is cuter after all.)

Suzune is dressed casually but follows the basics and properly wears her blazer. The color is almost black, so it suits fair-skinned Suzune well.

And Suzune’s thighs are going up the stairs in front of me, swaying her gray skirt. Honestly, I can’t look away.

But now seems like a bad time. If I peeked, I’d probably go past anger and disappoint Suzune.

Phew.

I decided to obediently follow without doing anything unnecessary.

※

When we went out to the rooftop, the wind blew through.

Suzune’s skirt lifted up softly.

Holding it down with her hands behind her, Suzune glared at me sharply. She’s gripping the edge of her skirt tightly.

I’m glad I didn’t peek on the stairs.

※

The silence is painful. I have to say something.

“U-um. About Saitou’s talk earlier.”

When I broached the subject, Suzune played with her left earlobe. She narrowed her eyes looking at me.

“The other girl, could it be Kei?”

“Huh? Why Kei?”

“Nothing. Kei was interested in you before, so I thought maybe…”

Is that about when I eavesdropped?

It’s true that Kei said things like ‘Shinomiya seems really nice’ but.

No no, that can’t be.

“It’s not. What about you, don’t you have a guy?”

Wait, am I maybe jealous?

“Huh?”

Suzune became even more displeased.

“What’s wrong?”

“That means you don’t believe me.”

Ah, this is my fault.

“Sorry. You convey your feelings so much, there’s no way that’s true.”

Suzune crossed her arms.

“Hmph. I can’t think of anyone but you. Even kisses, and beyond that, I’ve decided to give them to you. Though in front of the person, it’s honestly embarrassing.”

Suzune’s cheeks turned slightly red.

“I’m innocent too.”

“‘I’m innocent’ is usually what bad people say though.”

Suzune giggled.

Apparently she’s back in a good mood.

Thank goodness.

Getting so jealous, getting so anxious.

These were things unthinkable before summer vacation.

※

We sat side by side on the external stairs by the tower.

There are no tall buildings on the west side, so the view extends to the distant mountains. Maybe because the weather is good today, the greenery looks more vivid than usual.

“Amazing. I can see so far.”

Suzune held down her bangs blowing in the wind.

“Saitou’s prediction, weird flags are troublesome though. Well, I don’t have anyone but you.”

“H-hmm. That’s good then. I-It doesn’t matter who you like anyway!”

Suzune pursed her lips.

Those eyes were staring far into the distance.

I also stared in the same direction and spent some time.

※

A swallow is flying with its tail feathers flowing.

It looks comfortable.

※

Suzune started unwrapping her bento.

“Let’s eat our bentos soon♪ Um, you know.”

“Hm?”

“…Actually it does matter.”

While spreading her bento on her lap, Suzune continued speaking.

“I was jealous. Sorry. I apparently can’t stand you liking another girl. It’s the first time I’ve felt this way about a boy, so I don’t know what to do. But I like you that much, you know?”

After saying just that, Suzune smiled and opened her bento box lid.

(First time huh. That’s nice.)

Wait, Suzune’s bento has lots of side dishes and is well-made. Don’t tell me she just brought Mom’s bento?

I have two rice balls, a boiled egg (with shell), and marshmallows.

Suzune made an apologetic face.

“Um. Sorry only I have Mom’s bento. I wanted to make yours. But I’m clumsy, so it turned out like that. Mom will teach me, so I’ll be able to make it properly.”

It’s true that a wife’s cooking being good is better, and having her train during this opportunity isn’t bad either.

Wait, wife?

Wasn’t I hoping that someday Suzune would realize her feelings were a misunderstanding?

“Thanks. But why isn’t yours a bento you made yourself?”

Oh, I see. Could it be

To avoid suspicion from Mom?

If our parents suspect us, it’ll get complicated. Did she think about me?

Suzune answered.

“Because two rice balls aren’t enough for me. Peeling the egg shell is hard. And I hate marshmallows.”

“…”

This brat.

“You selfish thing.”
