My Little Sister Suddenly Confessed to Me, but What Am I Supposed to Do by Dating My Little Sister? - Chapter 81 & 82 & 83

Chapter 81: The Strongest Enemy Joins the Fray!!

‘…It smells really good… And something… a collaboration between something hard and something impossibly soft… It’s a bit hot for midsummer, but it fits so well. Um, when did I buy a body pillow…?’

“Onii-chamaaa! Shiori-neechamaaa! Morn—what are you two doinggggg?!”

‘Huh? Why do I hear a child’s voice? Wait, oh right, I’m not at home right now…’

“Guehhhh!”

“Kyahhh!”

Mitsuki jumped onto me—wait, why do I hear my sister’s voice too…?

“…Uahhhhhhh!”

My sister had crawled into my futon and was clinging to me like a koala. And I, mistaking her for a body pillow, had been hugging her back…

“Shiori-neechama!! That’s unfairrrr!! Let gooooo!!”

“Ehehehehehehe.”

“H-hey, Shiori, when did you…?”

“Let gooooo!”

“No, Mitsuki, don’t get in my futon either!”

“No way! I’m not letting go, Onii-channnn!”

“No fair! Then Mitsuki too—Onii-chamaaa!”

“Wait, let go! This is bad! Mornings are dangerous! Seriously dangerousss!”

###############

“I-I’m exhausted…”

After being attacked by both of them this morning, I’m riding the train in a state of physical and mental exhaustion.

“So we rushed to the station, and I didn’t say anything then, but Mitsuki, what’s with that outfit?”

After that chaos, we jumped up, leisurely ate breakfast, and then my aunt drove us to the station.

“Ehh, Gothic Lolita style?”

Ultra-long twin-tails in braids with red ribbons, a black one-piece dress with frills at the chest. The skirt portion is short with a flared hem, and gathers accent it. She’s wearing black knee-highs with the area near her absolute territory in a fishnet-style pattern. Isn’t this outfit dangerous for a fourth grader?

“More than Gothic Lolita, Mitsuki, you’re already a loli.”

“Hehe, how is it, Onii-chama? Am I cute?”

“Yes, yes, cute, cute… And Shiori, what’s with your outfit?”

I asked my sister, who was sitting across from Mitsuki.

“Ehh, white Gothic style?”

My sister had her hair in a side-tail with a small ribboned hat. She wore a white one-piece dress with a slightly open chest area, covered in frills—more frills on the chest, and even more on the skirt. If this were a light novel with an illustrator, the sheer tedium of drawing this outfit would probably start a fight. Good thing there isn’t one. White knee-highs and what looks like a garter belt in her absolute territory make my heart race.

“So that’s why you went back to change after seeing Mitsuki…”

“Ehehe, am I cute?”

“Yes, yes, cute, cute. I can’t believe you brought all that…”

She had a slightly large carry-on bag, but how much did she pack from home?

“I’m copying Shiori-neechama!”

“I brought it from the start, so it’s not copying!”

“And this morning you hugged Onii-chama! That’s not fair!”

“Onii-chan was hugging me and I couldn’t escape!”

I mean, I thought you were a body pillow—a premium-grade sister body pillow. With that hugging comfort, you could easily sell it for 100,000 yen…

“That’s unfairrr! Then Mitsuki should have hugged you and not let go when we were sleeping together last night!!”

“Sleeping together?! Onii-chan, you slept next to an elementary schooler?!”

“No, no, no, no!”

It’s before noon, so it’s not completely packed, but there are quite a few people on the train. And in rural Azumino, a gorgeous high schooler and elementary schooler in white Gothic and near-Gothic Lolita outfits are drawing a lot of stares. Some are even whispering things like, “Isn’t that Mitsuki-chan from the Yamanoi family?”

And then came Mitsuki’s comment just now.

“Eh? Who’s that? He’s too young to be Mitsuki-chan’s father, right?”

“Right? Did she even have an older brother…? And that cute girl just now looked like she was clinging to him.”

“Should we call the police just in case…?”

Suspicious whispers are rising around us…

“Alright! My cousin, Mitsuki! My sister, Shiori! We’re getting off soon!!”

I’m scared of being reported! Scared of being banned! Thank god it’s close—if this had been all the way to Matsumoto, it would’ve been really bad. There might have been people waiting at the station to question us.

We took a bus from the station and arrived quickly at the Daio Azumino Wasabi Farm. Wasabi requires large amounts of clean water and apparently doesn’t grow well in high temperatures.

Though called a farm, it’s been turned into a tourist attraction, with souvenirs and food seeming to be the main focus. In the center of the facility, a beautiful clear stream flows where wasabi is cultivated. Maybe because it’s sensitive to sunlight, it’s covered with black netting, so you can’t see it very well from above. There are stairs leading down, and when you descend, it becomes like a walkway where you can observe the wasabi cultivation.

“Wow, the water is so clean!”

My sister let out a voice of admiration at how clear the water was. The wasabi appears to be planted in gravel rather than soil, so the water is completely clear, making the green wasabi stand out. The flow of water becomes somewhat complex due to the gravel, creating a slightly geometric landscape.

You can walk all the way around the farm, and we walked to the edge while sightseeing.

“The water wheel is over here!”

Mitsuki, having been here before, guides us. We climb the stairs, cross a somewhat quaint bridge, and a river with abundant water flow comes into view a short distance from the farm.

“Th-this is so classic… but it’s nice. It’s calming.”

A clear stream flows, water plants reflected in it, and there’s the rattling water wheel. The water wheel is covered in moss, creating a really nice atmosphere.

“Wow, this is lovely!”

“No matter how many times I see it, this scenery is wonderful…”

Their words make my heart flutter. Most high schoolers and kids would probably find this boring. I don’t like crowds or downtown areas, so I suppose I really am an outlier.

It was the same in Ishigaki Island—when someone shares my values, when they’re moved by the same scenery I am, I feel an overwhelming tenderness toward them.

The two of them link their arms with mine, and together we gaze absently at this scenery.

Shiori, Asami, Michiru, Mitsuki—having people close to me who share in the emotion of the landscapes and scenery I witness… feeling grateful for that happiness, the three of us quietly gazed at the view for a while.

Chapter 82: The Strongest Enemy Joins the Fray!

“I wanted to look a little longer…”

We had finished sightseeing the water wheels and were now having lunch.

“Shiori-neechama, being next to Niichama is unfairrrr!”

“It’s not unfairrr! First come, first served!”

The bickering started again. I can’t tell if my sister is becoming an elementary schooler or if Mitsuki is a high schooler, but they’ve been fighting on the same level since yesterday.

At the water wheels, a struggle for my arms broke out.

Being fought over by two girls in such conspicuous outfits felt like a constant “social death” check.

I guided them here to escape, but the arguing just resumed.

“Anyway, it’s lunch. What should we order?”

I thought about the famous wasabi-don, but the shop was crowded, and the photos showed a bowl of rice with just bonito flakes and raw wasabi.

It felt a bit much, so we entered the Soba shop next door.

However, the way these two stood out…

They were attracting so much unwanted attention that the staff and other customers were staring.

“Ugh, I feel so out of place…”

I realized that I, sandwiched between them, was looking extremely suspicious.

We just got here, but I already want to eat and leave.

“Niichama, what are you having? Mitsuki wants tamagoyaki~”

“Dashimaki tamago is a side dish, isn’t it? Is that enough for you?”

“Yeah, and then I’ll have a little of yours~~”

“Eh? Then maybe I’ll order a large portion.”

“Mutter mutter… doting on Mitsuki-chan again… Onii-chan really is a loli…”

My sister started grumbling beside me. I’m not a lolicon! …Right?

“You’re wearing loli fashion, what are you talking about?”

“I only matched the preferences of the books Onii-chan usually reads! Also, the spot behind the bookshelf is too easy, it’s boring. You should find a different hiding place!”

“…Again… it was found againnn! Did I overthink the ‘secret’ too much?!”

I have no more hiding spots left… Maybe I should buy a PC… but Shiori would probably find a hidden folder or password easily.

“Niichama!! You have such a wonderful hobby? If you had told Mitsuki…”

“Waaaa! Waaaa! Waaaa!”

Stop itttt! I’m at my limit! Mitsuki, you’re saying something totally different from yesterday!

The stares from around us are painful… I’m seriously going to be reported.

…Yes, we ate. Wasabi Soba. It came with wasabi on the side and was delicious.

They say Soba isn’t great in summer, but it was good here.

Honestly, I can’t really tell the taste in this situation.

We finished quickly and went outside.

“Alright, let’s buy souvenirs, eat soft-serve, and go home…”

I’m at my limit. I’m tired.

“Soft-serve~ wa-sa-bi soft-serve~”

My sister skipped toward the shop while singing.

“Neechama is such a child~~”

Well, she is still a child by age, and Mitsuki is even more so, though I don’t even know anymore with her.

Shiori got wasabi soft-serve, Mitsuki got regular, and since the Soba wasn’t quite enough, I ordered a minced meat cutlet.

It had wasabi stems and leaves in it—very tasty.

“Onii-chan, here, ‘ahhh’~”

The bite of wasabi soft-serve I got from my sister had a hint of flavor but wasn’t spicy. It was actually good.

“Ahhh! Unfair again! Niichama, have some of Mitsuki’s too, ‘ahhh’!”

Yep, it’s regular soft-serve. I’ve gotten used to the “ahhh” treatment.

Am I a normie? I remember seeing high schoolers sharing soft-serve in a park once and wishing a meteorite would hit them…

Afterward, we went to the souvenir area and bought some wasabi snacks.

I noticed raw wasabi is quite expensive—one root could easily be 2,000 yen.

“Alright, let’s head back.”

“Ehhh, already?”

They complained, but we were standing out too much.

I wanted to visit one more place, but it was getting late, so I decided to save it for another day.

“Now!! Shiori-neechama! It’s time for the showdown!!”

You’re actually doing this…

As soon as we got home and changed, Mitsuki demanded a match.

“Fine, I won’t lose!!”

And you’re accepting it… You never learn, sister…

“Let’s bet a genuine, solo date with Niichama for tomorrow, Shiori-neechama!!”

“…Fine. I’m getting serious!!”

I mean, you were pretty serious until now…

“Niichama, you pick the game!”

Seriously? What’s left? Go, Shogi, Animal Shogi, Gaiter, Ohello…

Go/Shogi feels like Mitsuki’s territory. Gai*ter is psychological, so that’s Shiori.

What about Animal Shogi or Othello?

“Then, Othello…”

The moment I said it, both their eyes lit up.

“Tomorrow will be a solo date with Niichama, hehehe~”

“Tomorrow will be a solo date with Onii-chan, ehehehe~”

Both seem very confident.

Othello: a simple game played on an 8×8 grid where you flip stones by flanking them.

If you get 34 out of 64 stones, you win.

“Niichama, hide a stone in your hand. Neechama, guess if it’s black or white.”

They’re deciding turn order. Apparently, it’s debated which side is more advantageous.

“Black!”

Shiori guessed. I opened my hand—it was white.

“Mitsuki gets the choice! Mitsuki chooses ‘Victory in case of a draw’!”

“Huh? It’s not black or white?”

“Niichama, it’s in the official rules. You either choose the color or choose to win if it’s a draw.”

There’s such a rule…? Mitsuki is declaring she won’t let it be a draw. She’s serious!

“Fine. Then I’ll take white and go second.”

Fittingly, it’s a match between today’s Gothic Lolita and White Gothic styles!

Wait, what am I even saying?

“Then let’s begin, Shiori-neechama!!”

Mitsuki placed a black stone and flipped.

Shiori quietly placed a white stone and flipped.

For a while, only the rhythmic sound of stones flipping echoed in the room.

Their serious faces made me tense up too.

In the beginning, the strategy is to flip as few stones as possible to keep your options open.

Both knew this and were flipping the minimum.

The mid-game arrived. Stones started hitting the edges.

The key is not letting the opponent take the four corners, but if they do, the edges become the turning point.

The stone count fluctuated back and forth. Space was running out.

“It’s over, Shiori-neechama!!”

Surprisingly, Mitsuki placed a stone in a spot that practically begged Shiori to take a corner!

“Kh, it might be a trap… but if I run now, Onii-chan will laugh at me! I have to go for it!”

Honestly, your serious face is already a little funny…

Shiori took the corner!

“You fell for it…”

Mitsuki placed a stone right next to the one Shiori just played.

She had intentionally given up the corner to increase her own move options on both sides.

“Kh… but if I take the opposite corner, I’ll likely win!!”

The end-game began. A scramble for the corners!

“Ah!”

“Ah!”

They both cried out. Shiori ran out of moves.

“Pass…”

A potentially fatal pass. But Mitsuki froze.

“Wait, this means…”

Yes. If Mitsuki played in any of her available spots, it would inevitably give a corner to Shiori.

Victory was approaching for Shiori, who already held one corner.

Mitsuki’s eyes were moving at high speed. Was she calculating every remaining move?

“I can do this!!”

Mitsuki made her move…

And the match was decided. The difference was a single stone.

The winner is…

Next time! The author decides if they like sisters or lolis… maybe?

Chapter 83: The Strongest Enemy Joins The Fray!

“29, 30, 31… 1, 2, 3, 4…”

“Mitsuki-chan~ It’s the same no matter how many times you count it~~”

My sister stood up in front of the board, folding her arms as she looked down at Mitsuki.

“…Wh-why…? I read so many strategy books! I never lost online!!”

“Strategy books are useless in the face of the power of love. Right, Onii-chan?”

She says such embarrassing things so boldly right in front of Mitsuki…

“Uuuuu, uaaaahhh! I lostttttttt!”

Mitsuki slumped onto the table and began to cry. I told you to stop…

“Crying won’t help youuuu! Tomorrow, Onii-chan and I are going on a dateeee!”

She lifted her head, but there were no tear tracks. Fake crying, huh…

In the end, it was a one-point difference: 31 to 33. The “Loli vs. Sister” battle ended in my sister’s victory. (What, you’re surprised? Look at the title of this series.)

“Onii-chama!”

Mitsuki pulled herself together and looked at me. What now? Is she going to say something troublesome again…?

“Yes?”

“You’re not going to say it’s only until midnight today, are you?!”

“Ah? Oh, well…”

Mitsuki was the one who made me say that yesterday, though.

“Then tonight, Mitsuki… it’s okay if we sleep together, right!”

“Sure. Then let’s all three sleep in the guest room. We used to sleep together all the time back then.”

We often used to have big group sleepovers with the other cousins. They aren’t here now since it’s not Obon.

“Yeah! And since today is the day the three of us are together…”

“Since…?”

“The bath should be for the three of us too!!”

“…………No no no no no no no no.”

What is this elementary schooler talking about now…?

“Come on! Let’s go, Niichama! Wash my hair today too!”

“No way. We did that bit yesterday. People get bored of the same pattern.”

Is she out of material? This “self-proclaimed author” (if I get caught, will the news call me a “self-proclaimed author”?).

“Sigh… Niichama, do you know the word tendon? Repeating the same thing is what makes it comedy.”

“No, that’s not how it works… Ugh, Shiori, say something to her.”

She was quiet, so I thought she might have drifted off to another dimension imagining tomorrow’s date. But when I looked at my sister…

“Onii-chan!! Wash my hair too!!!”

No way… she’s completely fired up with competitive spirit… Give me a break…

“Shiori-neechama, Mitsuki said it first, so Mitsuki goes first!”

“Unfairrrr! Mitsuki-chan went in with him yesterday, so today it’s my turn!”

“Shiori-neechama, you said ‘first come, first served’ at lunch today!”

“That’s different from thissss!”

Wait, that’s not even the point! Is it already decided that we’re going in together? I haven’t said a word! I’m not getting in the bath with a high schooler and an elementary schooler. Yesterday’s intrusion was bad enough… What, are they testing how far they can go before I get banned?

After endless persuasion—and even a literal kowtow—I begged them to let me go in alone because I was exhausted. They finally let me. Why do I have to go that far?!

I went into the bathroom alone. Fortunately, this one has a lock, so I could relax without any intrusions. Though I did hear noises outside the door twice…

“Ehehehe, it’s been a while since our last date~”

The next morning, as promised, I head out alone with my sister.

Last night, I slept sandwiched between the two of them in an atmosphere of intense, mutual surveillance. However, my sister soon drifted off to her usual “other dimension,” and Mitsuki—perhaps thinking of tonight—started devouring books like Inoe’s Divine Move* or Hab Magic*. Thanks to that, I actually got some sleep.

“Mitsuki sent us off surprisingly well…”

I thought she’d make a fuss, but she even waved her hand and said “have a good time.” It’s almost scary…

“Onii-chan, where are we going today?”

“Ah, there’s a place I’ve wanted to go to.”

“Oh? Where?”

“The Chi*hiro Art Museum Azumino.”

“Chi*hiro?”

The name alone sounds a bit suggestive, doesn’t it? Iwasaki Chihiro. She’s famous for watercolors and children’s illustrations—most notably the cover of Kuro*yanagi Tetsuko’s Totto-chan: The Little Girl at the Window. It’s often in art textbooks, so everyone’s probably seen her work at least once.

“Oh, so it’s that illustrator. Do you like her, Onii-chan?”

Surprisingly, my sister didn’t know her. Well, art isn’t usually a major subject for exams. By the way, the painting of Reiko Standing by Kishida Ryusei in the textbooks was a trauma for me… Google it at your own risk.

“Her work has this soft, nice feel. And the scenery outside looked beautiful online, so I wanted to come here with you, Shiori.”

“Ehehehehe.”

I can’t possibly tell my sister that my first impression of Asami was, “Oh, she looks like a girl from a Chi*hiro painting…”

“There’s a museum in Tokyo too, but this one is larger and has lots of picture books. I’ve wanted to visit for a while.”

“Heeh, picture books? Has it been here long? I wish Mom had brought us when we were little.”

“Well, maybe it’s because it’s usually closed during the New Year’s holidays?”

By the way, it is open during Obon.

“Ah, I see. So that’s why we didn’t do much sightseeing before.”

That, and the fact that Mitsuki was always stuck to me like glue…

The route is almost the same as the wasabi farm yesterday; only the bus from the station is different. I wanted to come yesterday, but it was too late in the day. The reason being…

“Wow! It’s beautiful! It’s like a park! There’s even a pond!”

Yes, this place offers a panoramic view of the Alps. It feels quintessentially “Azumino.” I wanted to take my time and see everything, including this scenery.

“It looks just like the photos online. No, it’s even better in person.”

You can feel like you’ve been there just by looking at the internet, but no matter how well a photo is taken, it can’t beat the real thing. You don’t truly understand something until you go and see it. I was reminded of that once again.

“Alright, Shiori! Let’s have a relaxing Azumino date today!”

“Yeah! Onii-chan! Ehehehe.”

A date alone with my sister after such a long time. I wonder if it will actually end normally today?
