I Just Wanted a Peaceful Life After Transferring, but I Fell into a Rom-Com Trap and a Hidden Battlefield No One Knows About - Chapter 06: The Misaki Siblings' Daily Life – A Chaotic Morning from the Get-Go?

Chapter 06: The Misaki Siblings’ Daily Life – A Chaotic Morning from the Get-Go?

As a proper older brother, it’s only natural for me to dote on my little sister.

I may be an otaku obsessed with anime and games, but I always strive to be the best big brother for her.

Let me introduce her real quick.

My little sister, Misaki Umika, is fifteen years old and a third-year middle school student. At the same time, she’s also a newly debuted idol who has recently gained popularity and is quite famous in DARK City.

Having a famous idol for a sister might sound enviable, but honestly, I just wish she could stay an ordinary girl.

Fame brings scrutiny—every little action can cause unnecessary trouble, and she constantly has eyes on her.

As an idol, she has to endure the harsh gaze of the public, but for a fifteen-year-old like Umika, that kind of social pressure must be overwhelming.

That’s why, even though I don’t want her to be a popular idol, since it’s her dream, all I can do as her brother is silently support her from the shadows and act as her shield.

…Man, I’m actually a pretty amazing big brother, aren’t I?

After preparing breakfast and hanging out all the laundry from last night on the balcony, I headed to Umika’s room.

“Umika, time to wake up. You’ll be late for school.”

I gently shook her body… huh? Empty? Did she just disappear into thin air?

“Heh, Agent 001, you’re still too naive.”

A low voice came from the corner of the room. Ah… she’s playing one of her weird games again.

I cautiously surveyed the room. The bed was neatly made, the curtains were tightly shut, and the whole room was eerily quiet… too quiet.

“Come on, Umika, quit playing these weird games… just come out already.”

“No can do! The mission has already begun. Brother, I’m now in my ‘Spy Stealth Mode’!” (T/N: The brother is similar to how Yuki called Masachika, literally ‘Buraza’)

“…Huh?”

“If you don’t find me within three minutes, enemy forces will steal vital intel, and the mission will fail!”

“Huh? Huh???”

“Do your best, Agent 001… Timer, start!”

…Where does she even come up with this stuff?

But I’m used to it. Ever since she was little, she’s always been coming up with new pranks to pull.

Alright then, no way I’m losing this!

I swiftly scanned the room and began my search.

Bookshelf? Not here…

Closet? Empty…

Behind the curtains? Nothing…

Where the hell is she hiding!?

Just as I was starting to feel stumped, I suddenly heard a faint sound from behind me.

Beep…

Wait… this sound…

I turned around and spotted a small timer on the desk, displaying “00:58”.

“You actually set a countdown!?”

“Fufu, gotta have some tension, right?”

No… there’s zero tension here…

But thanks to that, I realized something—this game is different from her usual hide-and-seek.

She’s definitely hiding somewhere visible, just enjoying watching me struggle to find her.

If that’s the case…

I immediately peeked under the bed!

Gotcha!

A barely contained giggle leaked from beneath. Without hesitation, I reached out and yanked up the bed sheets.

“Ah! You found me!”

Umika, who had been hiding under the bed, let out a startled cry and scrambled out in a panic, like a spy whose cover had just been blown.

“No running!”

I lunged forward and grabbed her arm.

“Hmph, Agent 001, you really aren’t just some ordinary guy.”

“Cut the spy talk already… now get up!”

“Damn… I lost this round…”

Pouting, Umika stood up and dusted herself off.

“Brother, wasn’t that fun?”

“Fun, my ass. You’re always playing these childish games—”

Before I could finish, Umika grabbed my collar and shouted angrily.

“Hah!? You idiot! Who cares if it’s childish!? We’ve been playing like this since forever, haven’t we!?”

“I-I can’t breathe—let go!!”

She was practically strangling me, but I somehow managed to wriggle free from her grasp.

After taking a deep breath, I reluctantly gave in.

“Yeah, but… we’re grown up now…”

“Tch! You’re such a boring big bro! Not fun at all!”

“Well, sorry about that! But we don’t have time, so hurry up and get changed!”

“Che! Fine, fine!”

Unless there’s some special reason, taking her to school is one of my daily “missions.”

Of course, she could walk to school by herself, but her classes start earlier than ours, and since my school is a bit farther away, I have to leave home earlier.

Since our departure times are close, my route to school always passes by hers. That’s why I end up taking her almost every morning. Today is no exception.

After urging Umika to change her clothes, I left her room and carried the already-prepared breakfast to the dining table.

By the way… does this make me kinda like a housewife? If I get married in the future, will my wife be the one working outside while I handle things at home?

…That doesn’t sound so bad!

“Onii-chan, I’m done washing my face!”

“Oh, then let’s eat… Huh? Wait, you’re still not dressed?”

“Huh? Ah—oh, you’re right! I totally forgot! Ehehe~”

Umika scratched the back of her head with a big grin and, without hesitation, started taking off her pajamas right in front of me.

In an instant, her body was almost fully exposed, with only a pair of pink underwear covering her private areas.

There’s a difference between boys and girls, sure, but I’ve long since gotten used to this kind of thing.

Umika’s figure stands out even among girls her age. Especially in that area—she’s already surpassing most adult women. Many would probably be jealous.

But I don’t feel anything about her body.

Her so-called perfect proportions, the curves that could rival grown women—none of that means anything to me. To me, it’s all just “soft-looking objects.” Even her so-called girly underwear is nothing more than scraps of fabric in my eyes.

Maybe it’s because we’re siblings. We’ve lived together for years, after all.

“Hey, why do you always change right there on the spot?”

“It’s fine, it’s fine! Onii-chan sees me all the time anyway, right?”

“Well… yeah, but I am a guy, you know?”

I mean, sure, I’m not interested, but this is still pretty bad. If our older brother were here, he’d definitely get mad.

Oh yeah, speaking of which—Umika and I have another older brother: Misaki Takeru.

Our parents passed away in an accident a long time ago, so he’s been taking care of us by himself.

His job involves taking on assignments from organizations all over the world. Basically… he’s like a spy.

He’s rarely home, but at the beginning of every month, he sends us living expenses and supports our daily lives.

For the record, I sometimes tag along on missions in DARK City that he takes on. So in a way… does that make me half a spy too?

Hehe, that sounds kinda cool!

“So what if you’re a guy? We grew up together! Or wait—do you not like my E-cup?”

“It’s not about liking or not liking—wait, what? You’re an E-cup?”

“Ehh~? Want me to measure it for you?”

Saying that, Umika moved her hands in front of her chest. Just in case, I quickly stopped her.

“Hold it right there! Don’t do anything stupid! Just get dressed and eat, or you’ll be late.”

“Hmph. You used to look at it when we were little.”

“That was when we were little!“

“Eh, not much has changed, right?”

“It’s completely different…!”

Umika finally started getting dressed while I waited at the table.

“Oh yeah! Onii-chan, can you grab a milk from the fridge?”

She asked while still in the middle of changing.

“Got it…”

I was about to go get it when she suddenly smacked her forehead with a pat!

“Ah!”

“What now?”

“I just remembered—I drank all the milk yesterday…”

Jeez, don’t scare me like that… I thought maybe she had some important homework left or something, but it was just about milk…

…Wait. Hold on. Maybe for her, milk is important?

After all, that area of hers has changed dramatically over the past year. A year ago, she was completely flat.

Now that I think about it, she drinks milk every morning and night. Maybe she’s been doing it on purpose to make them grow?

…Who knows. Either way, we’re out of milk.

“I’ll buy some on the way home, so hurry up and finish changing.”

“Almost done!”

While getting dressed, Umika started fixing her hair. She looked pretty busy. If I’m not mistaken, next she’s going to put on makeup.

Can’t she just finish one thing before starting another?

“Don’t rush so much. Just finish dressing properly, and I’ll tie your hair for you.”

She’s already a popular idol, yet her daily life is a complete mess…
