My Little Sister Suddenly Confessed to Me, but What Am I Supposed to Do by Dating My Little Sister? - Chapter 51 & 52 & 53

Chapter 51: Student Councils Always Appear in School Stories, Don’t They?

It was mid-June, and outside, the rain drizzled (jito jito). The atmosphere in the student council room was also sticky (jittori).

Having held this meeting several times now, nothing had been decided at all.

If things continued like this, we’d go past the summer vacation deadline, so last time we agreed that everyone would think of something. But in the end, no one thought of anything—because all the ideas had already been exhausted.

When an idea was proposed, its flaws were pointed out. Without trying to fix those flaws, the idea was rejected the moment it appeared. They wouldn’t try to move forward from there.

For example: “That would require too many people,” “That would need a budget,” “That would take too long to implement,” “Who would get permission?” “Who’s responsible…?”

What? Are they doing this on purpose? The student council members were so dysfunctional it was unreal, and all my opinions were completely denied too.

My sister just watched in silence, and the Secretary as always only said “that’s good” or “that’s no good.” I had absolutely no idea what they were trying to do.

“President, since we’re running out of time, I think we should hold meetings every day starting next week.”

At the Vice President’s proposal:

“You’re right. At this rate, it’ll be summer vacation.”

The President agreed while glancing at the Vice President.

“That’s right.”

The Secretary only ever says “that’s good” and “that’s no good.”

“Is that all right with you two as well?”

With a feeling of do whatever you want, I gave my approval for now, and today’s meeting was adjourned.

When we tried to leave the school building, it had become a downpour. I was about to walk with my umbrella when my sister grabbed my sleeve and stopped me.

“Onii-chan, I don’t have an umbrella, so let me in.”

“Shiori, it was raining this morning, and we came to school together, so there’s no way you don’t have one.”

“Ehhhh, but I don’t have one. It’s fine, right?”

Even though I knew she was absolutely lying, I couldn’t refuse when my sister made that face.

“Can’t be helped. Here.”

“Yaaay!”

“Don’t wrap your arm around mine. You’re too close.”

They’re touching, they’re touching.

“Ehhhh, but I’ll get wet!”

“Yeah, yeah.”

I gave up and asked my sister while our arms remained linked.

“So, what do you think about the student council?”

“Hmmmm, the President was pretty troubled.”

“With nothing being decided at all, that would be troublesome—even for that President.”

“No. The Vice President is deliberately troubling her, so she’s troubled.”

My sister shook her head in denial.

“Eh?”

The Vice President is deliberately troubling the Student Council President?

“Yeah. She’s deliberately troubling the President.”

“Really?”

“Yeah.”

“Why?”

“Who knows? I don’t really understand the Vice President. Her emotions are complicated, or something.”

“Even you don’t understand, Shiori?”

“Yeah. What I understand is just Onii-chan. I don’t know everything—just about Onii-chan.”

“Why did you rephrase that?”

“That’s why I thought we should leave it alone, but starting next week, every day? I don’t want every day. My time for flirting with Onii-chan at home will decrease.”

“No, we’re not flirting. But yeah, what should we do…?”

While I was worrying, my sister abruptly took out her smartphone from her bag.

“Hold my bag for a sec, Onii-chan.”

Saying that, my sister used both hands in the rain and typed on her smartphone at an incredible speed.

“I don’t really want to do this kind of thing.”

Even while saying that, her typing speed didn’t drop.

After about five minutes, my sister raised her face from her smartphone and looked at me.

“Done. Let’s go home.”

Saying that, she started walking as if nothing had happened.

“What did you do?”

I moved the umbrella closer to my sister and asked.

“Hmmmm, I guess it’s a favor for now? After that, I’ll manage it this weekend.”

She clung to my arm again with her whole body.

My sister started something, but I have no idea what…

Monday, in the student council room—everyone’s faces, including mine, were incredible.

“These are the documents. All the student council has to do now is compile them.”

My sister had decided everything: the plan, implementation method, personnel, their placement, and report submitters—everything.

For example, volunteering at a kindergarten: the people going there were friends who wanted to become kindergarten or school teachers in the future. It listed the kindergarten near those kids’ homes, permission, the person in charge, implementation date, report submitter—everything was documented.

For example, fundraising at a station: this also had station permission, donation destination, participants, implementation date, station manager, person responsible for the money—everything was documented. What was amazing was that since everything was near the cooperators’ homes, there was almost no budget for transportation costs. Even the donation boxes had volunteers prepared to make them.

She probably requested cooperation from her friends and then their friends, selecting those who were available from there—but I couldn’t even imagine how many people were involved.

The content was perfect, all permissions had been obtained, and there was nothing to criticize. The attention to detail included requesting multiple report submitters in case something happened.

“All that’s left is to compile the submitted reports, but there are tons of people who want to do it even though that’s all there is. What should we do?”

In other words, she was saying: There’s nothing left for the student council to do—is that okay? Scary!

“We will handle that.”

The President answered while glancing at the Vice President.

“Ah, if you don’t have enough people, there are more than double the number currently helping, but sorry, the volunteer sites couldn’t prepare fast enough.”

She apologized in a tone that showed she didn’t feel bad at all, and furthermore:

“If you give me two more days, I can do double what we have now. What do you want to do?”

“Hii!”

At that outrageous proposal, the Secretary, Machiya-san, let out a small scream.

“It’s fine—this is plenty. Thank you so much.”

The Vice President answered with a smile in a hurried tone.

“If there’s no problem, I’ll send everyone a request, and I’ve asked them all to go on those days.”

My sister threw a questioning look at the Vice President—not the President—asking What will you do?

I didn’t miss the Vice President’s face showing a dubious expression for an instant.

The Vice President instantly returned to a smile:

“Well, there don’t seem to be any particular problems. President, what do you think?”

“Yes, that’s right. Then, Shiori-san, we’ll leave it to you. You’ve really helped us. Thank you very much.”

Confirming the President’s answer, my sister operated her smartphone:

“Sending the request from the other day… sent!”

I could see responses flood in all at once on my sister’s smartphone—acknowledgments.

Among them were messages like “Lucky!” “I wanted to do it!” “Ask me next time too!”

My sister looked at Shiroi-sensei:

“I’ve told them to hand the reports to Sensei, so please receive them.”

“Yes!”

The teacher responded in a strained voice.

“Well then, the meeting is over. Let me know if anything comes up.”

Saying that, my sister stood up.

“Let’s go home, Onii-chan.”

At those words, I left the student council room with my sister.

Just before closing the door, while the student council members looked at us, I caught sight of the Vice President—the only one with a terrible expression, looking down—but I quietly closed the door as is.

Chapter 52: A Serious Date

The student council uproar has finally subsided.

Neither my sister nor I could just sit back and do nothing after making others work, so we spent the weekend putting our all into volunteer activities.

Once everything was wrapped up and the reports were submitted—since it was Shiori’s request—the volume of reports was apparently staggering. Right now, the student council is likely buried under a mountain of data entry and organization.

However, the President, the Vice President, and even that Secretary each had their own quirks. Between the President’s dual personality and the Vice President’s final attitude, I have a bad feeling we’ll be entangled with them again in the future.

Now, as final exams approach, we were having our usual tea party in the living room when my sister suddenly raised her voice.

“Onii-chan! This is a disaster!”

“Hmm? What is it? Did something happen?”
Not the student council again? I’ve had enough for a while. I sipped my coffee and asked back as calmly as possible, given how flustered she was.

“We haven’t gone on a date at all lately!”

“……”

Well, I figured it was something like that.

“If this keeps up, it’s going to be a ‘title scam’!”

“Look, the moment we dissolved the ‘lover relationship,’ it already became a scam. What are you even talking about?”

“I want to go on a date.”

“I think using that specific person’s catchphrases too much is risky, but… a date, huh?”

“Ehhhh, come on! I worked really hard this time, didn’t I? Where’s my reward?”
Like a puppy that brought back a ball begging its owner for praise, Shiori made a dog-like pose on the sofa, staring at me with puppy-dog eyes. Cute. She’s really cute. Just… please stop shaking your butt instead of a tail.

“I mean, you didn’t just ‘work hard,’ you were too amazing. It was practically cheating. It wasn’t ‘I’m OP’ (Ore TUEEEE), it was more like ‘My Sister is OP’ (Imouto TUEEEE). It feels fresh, yet like something you’d definitely find if you searched for it on Narou.”
I tried to gloss over it by patting her head.

“I don’t know what you’re talking about, Onii-chan! Just take me somewhere!”
I guess just a head-pat wasn’t enough to distract her…

“Fine, fine. Where to this time?”

“Hmm, Akihabara?”
Running out of ideas already?

“I want to go on a trip with just the two of us.”

“If it’s a day trip, sure.”

“And then the last train leaves, and the two of us… ehehehehe.”

“Yeah, yeah. Try not to go to ‘another world’ and make the author depressed again.”

“But you promised a trip with an overnight stay!”

“Shhh! That’s the secret one. The one you aren’t supposed to say. The one we have to save for later!”

“I want to elope with you to a place where no one else is, Onii-chan.”

“Right, right. So just a long-distance outing.”
The “place where no one is” part is a problem. An uninhabited island?

“Um, I heard the ‘suspension bridge effect’ is good, so somewhere high up or dangerous would be great.”
She’s actually started Googling it.

“Just don’t fall off.”

“Then let’s fall in love together, Onii-chan!”

Personally, just sitting here talking nonsense with my sister is the best thing for me.

My sister tilted her head and put a finger to her lips in her usual calculatedly cute pose.
“I want a classic high schooler date.”

I’ve never dated anyone but my sister, so I don’t know what ‘classic’ is…

“A classic date, huh? Let’s try Googling that.”
I searched on my phone.

“……”

“Where did it say, Onii-chan?”

“Each other’s houses…”

“Yeah, we’re already there.”

“Bowling.”

“We did that the other day. I wanted to do it a bit more, though.”

“Having tea at a café.”

“If it’s a ‘sister café,’ we do that almost every day. We even did a maid café.”

“We’re doing them! We’re totally doing ‘classic dates’ already!”

“U-um, yeah. We’re totally ‘normies’ (riajuu).”

“Hmmmmmmm.”
The two of us crossed our arms and groaned in a cliché pose of worry.

“Onii-chan, if you had a girlfriend, for example, is there nowhere you’ve ever thought about wanting to go?”

“Hmm… her room?”
Every healthy young man thinks that. Probably…

“We did that last time too…”

“What about you, Shiori? Don’t you have anywhere?”
My sister answered with such force it was like she was biting back, as if saying Why are you asking me that now?

“My only ‘imaginary boyfriend’ is you, Onii-chan! Wherever you take me, even if it’s hell, I’ll have fun!”

“There she goes again, saying stuff like that with a straight face. Fine! Then let’s go to hell.”

“Okay, but where is it?”

“Isn’t there one around 3-chome?”

“Definitely not. I walked through there the other day.”

“Could this be… a ‘rut’ in our relationship?”

“It means we’re practically a married couple already, ehehehehe.”

“Man, you never give up, do you?”

“I don’t care where it is! Just take me! I want a daaaaaate!!”
She started flailing again. Lately, her selfishness has been accelerating.

I guess she’s feeling completely secure because of that “we can’t be separated” thing. But thinking that this might be her true self, I honestly feel like it’s a good thing…

Still, I should probably… that’s it!!

“Alright! I get it! I’m going all out too, Shiori. On our next date, I’m going to date you while thinking of you as my actual girlfriend!”

“Eh? You weren’t thinking of me as your girlfriend…?”
She slumped down in shock.

Well, because you’re my sister…
I pulled myself together.

“Shiori, you worked really hard on that student council thing. This time, I’ll work hard for you.”

“Yeah! …If Onii-chan is going to be in a ‘lover mood,’ then maybe… not just this once, but forever… this might be my critical moment… I’ll take this chance to make him…”

Hearing her start to mutter something under her breath, I’m already starting to regret this…

A “serious date”—I don’t even know what being “serious” about a date means. Am I going to be okay? Is this bad? I already said it. Will I be able to withstand my sister’s attacks? Maybe I should have set this to 15+ after all?

Chapter 53: A Serious Date

That night, after the date had been decided for the next day, Shiori was ecstatic.

“Kyaaaaaaaaa! Onii-chan… Onii-chan is… fi-finally, finally going to treat me like a girlfriend!”

The moment she entered her room from the living room, Shiori threw a victory pose toward the heavens.

“He said he’d date me as a lover tomorrow… that’s basically a confession, right?!”
She pressed her hands to her cheeks, swaying her body back and forth in a “no-you-didn’t” fit of delight.

“Lately, he’s seen me as nothing but a little sister. Even when I say I love him this much, he’s just been giving me ‘yeah, yeah’ responses. But maybe he was actually listening a little bit.”

Shiori crossed her arms, reflecting on everything up until now.

“Finally… finally, Onii-chan is getting serious. I did it!!”
She didn’t care at all about the mountain of work she’d done for the student council; Shiori was praising herself solely for securing the date invitation.

“But I can’t be satisfied with just this. I have to appeal to Onii-chan more and more tomorrow!”

“Plus, Onii-chan is super motivated. This is a huge chance. Right… maybe I should just go ahead and create a fait accompli…”

“No, that’s no good. I can’t be satisfied with just a fait accompli. I have to make Onii-chan my captive all at once, to the point where he thinks he can’t live without me…”
She hadn’t noticed that she was already the one who was a hopeless captive.

“Ah, but do I have that kind of charm? A way to make Onii-chan my captive… I wonder how you draw a magic circle?”
She started Googling on her phone. Hey!

She spent a while researching magic, curses, and hypnosis… but then she remembered there was something she had to do before all that.

“That’s right, I have to pick out what to wear tomorrow first.”
Shiori stripped on the spot and stood before the closet in nothing but her underwear. Her reflection appeared in the mirror, and she gazed at her own slender, beautiful body.

“Uu, it’s the same as always…”
She sighed as she touched her own chest. Though they were by no means small, she selfishly felt they weren’t enough to satisfy her brother’s preferences.

“I wonder what Onii-chan likes? Hmmm, the ‘femme fatale’ look? The cute look? Wearing nothing at all?”
She pulled out underwear from the second and third drawers under her clothes in the closet, holding them up against herself while looking in the mirror.

“Ah, that’s why I wanted to ask him which ones he liked the other day! Maybe I should go to Onii-chan’s room right now and have him pick which one is best?”

“Ah, but that’s no good, right? Since it’s the first time he’ll see them, he won’t be as happy if I show him beforehand.”

A wise decision. If you did that under the assumption of showing him, tomorrow’s date would be cancelled.

“Alright, for now, I’ll go with something new, something cute, and a matching set.”
Finally having decided on the underwear, one would think the clothes would be next…

“Ehehehehe. Onii-chan as my lover… maybe… ehehehehe.”
The moment the underwear was decided, her usual delusional habits kicked in.

She went back to “another world” known as Delusion for a while. When she returned, the “Shiori Collection” fashion show began.

“What would be good? It looks like it’ll be pretty hot tomorrow, so a bit of skin is okay, right?”

“I just don’t know Onii-chan’s taste. No matter what I wear, he just says ‘it’s cute.’ ‘Cute’… Onii-chan said I’m cute… ehehehehehehe.”

— Please wait a moment —

“Hah! No, no, I still have tons to do! Clothes… well, there’s always a chance we’ll run into someone we know, and Onii-chan might not feel safe making a move… so maybe a hat and glasses… Eh? Onii-chan… making a move? E-eh?”

“That’s right, yeah! Declaring we’re lovers means that kind of thing, doesn’t it? E-eh, what should I do? What do I do? Should I just keep my eyes closed? But it’s Onii-chan’s first time too, right? E-eh, what do I do?!”

I’ll leave the extent of Shiori’s imagination to yours.

“Wait, hold on. I wonder if they’ve set this to 15+, or maybe 18+?”
Not at all.

“F-for now, I have to go to the bath. Maybe I should re-select the underwear? Ahhh, I haven’t finished researching the magic circles yet!”

After that, she spent several hours in the bath and several more hours picking out clothes. By the time she was done, it was late at night.

“Ah, what should I do? Onii-chan… ufu, ufufufu, ufufufufufu, ufufufufufufufufufufu…”

Like the tempo of a certain vampire’s laughter, an eerie laughing voice echoed through the room in the dead of night.
