Part 1

"Hey—you said that you wanted a little sister, right?"

The night of a certain day near the middle of summer vacation.

Toujou Basara heard his father say that so resolutely.

It was during their dinner—just as Basara stood up to get a second serving of

curry.

"I didn't say that. Did the spice get into a bad place of your brain?"

Basara said so wearily over his back, then opened the lid of the rice-cooker.

"Such a weak reaction...it's a little sister, you know, a little sister. It's

something guys want so bad that they start drooling."

"I'm afraid that a little sister doesn't fill my stomach."

Like he would go along with his father's antics. He had a great appetite. The

stomach of a high school boy wasn't to be underestimated. Once he finished

loading his plate with the rice, Basara moved in front of the pot with the

curry on the stove. He poured the substantial sauce over his rice, then

returned to his own seat.

"Huh? Where are the pickled vegetables?"

The bottle filled with the curry's relish had disappeared from atop the table.

In front of him, his father that sat across of him held the bottle with the

pickled vegetables in one hand and said with a triumphant look on his face,

"Hey, let's talk a bit more enthusiastically about a little sister."

He showed a smirk. Basara made a sigh of resignation and looked at his own

father—Toujou Jin. That father at a good age, tried to discuss the merits of a

little sister with his son over dinner.

Putting it into words was quite painful. He felt a slight killing urge.

"Enthusiastic...actually, did I really say I wanted a little sister?"

"What...you don't remember?"

Jin said astonished.

"You said 'I want a little sister', which sounded like a light novel title, with

sparkles in your eyes—about ten years ago."

"Like I would remember that!"

Ten years ago, Basara was still 5 years old. Without a doubt, it had only been

childish nonsense. However, Jin put up a hand with "Calm down".

"A little sister is nice, cute, kind and soft. She'll wake you up in the

mornings."

"Well, that might be..."

"Yeah. Besides—you can do all the perverted stuff you want."

"Don't tempt your son into crimes! Actually, it would be scary instead if there

was such a little sister!"

Such a little sister only existed in 2-D.

"What's up with you, dad...? You wanted to talk about a little sister that's

likely to fall under the metropolitan regulation that bad?"

[1]

"I wasn't really talking about fiction. Though the perverted stuff was certainly

a joke."

Jin forwarded the bottle with pickled vegetables by sliding it over the table.

"Well, in short, what I want to say is: Do you like or hate a little sister?"

"What kind of survey is this? Well...a little sister from a drama or manga

aside, I heard that a real little sister isn't all that great. Like they're cheeky and

crude."

"Then, in other words, you would be fine with a cute little sister."

"Well... Guess so. —Actually, where are these questions leading to here?"

On Basara's words, Jin replied shortly with, "Yeah, well", then showed a

suggestive smile.

And then, he spoke the words that would change Toujou Basara's fate.

"Aren't you glad—to get a cute, little sister?"

Part 2

Blue, wherever you looked. That was the colour of the sky on that day.

The weather was nice. The cicadas were chirping like a scream of the heat, as

the temperature reached a new record high in history. It was an early

afternoon in midsummer. Basara had come to a family restaurant in front of

the station with Jin.

"I mean, seriously...?"

Toujou Basara mumbled in a still doubtful tone.

—Last night, Jin brought up the topic of a little sister. That was a flag for his

second marriage.

Because he had picked, "If it's a cute little sister, I like her," from the choices,

they came to meet her right away today.

"Stop sulking... When I called them, they said they wanted to meet and greet

you as soon as possible. Besides, I asked you if today would be fine with

you."

"Well, yeah..."

Certainly. Basara had told Jin, who had asked with his cell phone in one

hand, "I don't mind," as he still couldn't comprehend the situation and was

going with the flow.

However, after taking counsel with his pillow, he ought to think about it once

more after all. Jin getting remarried meant that Basara would get a new

family. And not just a little sister, but he might also get a mother.

...But.

Yes—that was still theoretical.

Along with Jin, the other family and the girl who was to become Basara's

little sister were also sympathetic to the remarriage. But, despite that, Jin's

remarriage was not yet set in stone. In other words,

...I'm the last one to get convinced, huh...

With the final conclusion resting on his shoulders while all other obstacles

had been cleared, it was a somewhat annoying topic. When Basara thought of

what kind of predicament he was in, an electronic sound suddenly sounded

from the entrance of the restaurant. It signalled the arrival of a customer.

While inadvertently putting himself on guard, Basara looked towards the

entrance and made a sigh of relief. It had obviously been a different family.

"What are you getting tense for every time a customer comes in?"

"Wh-What does it matter to you…really."

While placing his cheek on top of his palm, Basara looked at the newly

arrived family.

—A father, a mother and a child.

It was natural happiness. Thus, something really precious.

Toujou Basara wondered if he could get that happiness, which was what he

wanted at that time.

—But what were the actual conditions?

He didn't know. A family of females was something unknown to him. But—

he might get an answer to that now. By meeting with the people that might

become his family in the future.

—And, he didn't even know himself why he did so.

It wasn't because of the electronic sound that signalled a new customer, nor

was there really anything drawing his attention. Despite that, as if he was

being controlled, Basara—suddenly shifted his gaze towards the entrance of

the restaurant.

"——"

With leisurely steps, two girls entered the restaurant.

One of them was around the same age as Basara, likely a high school girl.

The other one was younger than Basara. Because she was rather short, she

looked both like an elementary and middle school girl. Those two were likely

sisters, but—

"...Uwah."

He unconsciously leaked a voice out of surprise. So far, he had seen a cute

girl on the street before. He also had inadvertently stopped and turned around

to her.

But—the girls who had come in, completely surpassed that basic level.

After all, the other customers who had noticed the girls, also had their gazes

pinned down on the two of them. Soon enough, the girls were led away by an

employee to a table on the opposite side of Basara and Jin.

When he looked at their backs—another new customer entered.

It was a woman in her twenties with a peaceful aura together with her

daughter in elementary school.

...Were they finally here?

Inadvertently, Basara stiffened up and at the same time, the two came closer

like they had noticed him.

No doubt. Basara stood up from his seat with attitude to the coming mother

and daughter.

"N-Nice to meet you... I'm Toujou Basara!"

However, the woman in front of him looked at Basara in bewilderment. She

might have been surprised by the sudden greeting. Basara hastily tried to save

the situation. Suddenly, a fist hit the back of his head.

"Oww! Wh-What are you…huh!?"

"Sorry about my idiot."

Before Basara could turn around, Jin forcibly grabbed his head and lowered

it.

Basara got his body forcefully lowered until he was bending forward, but still

managed to shake off Jin with force.

"Who are you calling an idiot!? To smooth out your sudden remarriage, I just

tried to—"

Then, the mother and daughter passed by in front of Basara.

"Eh…?"

When Basara followed their backs with his eyes, the pair sat down at the next

table—beside a man that was likely the husband. The husband welcomed his

wife and child with a smile, but towards Basara, who had called out to his

wife, he sent a short, strict glare.

…Ehm, in other words.

It was a misunderstanding. To Basara, who was about to explode out of

awkwardness from his painful mistake, Jin spoke.

"You're too nervous...go wash your face and calm down."

"...Sorry. I'll do so."

He said so wearily, whereupon Basara unsteadily headed for the toilet in the

back.

...Just what am I doing?

Getting nervous by himself, blowing his fuse by himself, getting elated by

himself.

At that rate, it was unknown what kind of failure he would pull on the

meeting. Like Jin had said, he ought to calm down a bit. While looking down,

he opened the door to the toilet and set a step inside.

"Eh—?"

Toujou Basara raised his face and froze up.

In the opened room—stood a girl.

At that moment, an awkward silence fell onto the small room.

The girl in the toilet was the beautiful older sister from the pair of sisters that

had entered the store earlier.

The girl had bent slightly forward, had rolled up her skirt and had both her

thumbs in her white panties, as she was either pulling it down or pulling it up.

With all thoughts stopped from the sudden happening, she looked at him

dumbfounded.

But it was a misunderstanding. Basara had by no means opened the door of

the female toilet.

The toilet merely was for both genders. She likely had used that double

gender toilet, as the female toilet was occupied. However, that double gender

toilet had a defect that was known to the usual guests—the lock didn't close

properly. Therefore, the girls who knew of that, avoided using that toilet if

possible. The restaurant had even posted a small paper saying "Please lock

the door properly" inside to avoid any troubles. But even if one thought it was

properly locked, it could happen that it actually wasn't—yes, just like right

now. Basara hastily tried to close the door and turn on his heels—but

suddenly he heard a 'certain sound'. It was the sound of the girl taking a deep

breath. An action taken before a scream.

"—Hey, wait!"

"Mmg!?" Basara narrowly managed to quell the scream and made a sigh of

relief for now.

...Wait, what am I doing!?

Before he had noticed it, Basara had completely stepped into the toilet and

covered the mouth of the girl.

That wasn't good. It should have been an unfortunate accident due to a

misunderstanding, but the situation had worsened so much that even excuses

were useless now.

"Sorry for scaring you, but please—listen to me without making a ruckus.

This wasn't on purpose. It's an unfortunate accident, a misunderstanding…"

That the occupied toilet door opened from the outside meant that the person,

who didn't lock the door properly, was at fault. In other words, the girl. On an

emotional level, she was a victim. Therefore, Basara explained about the

defect of the lock and about the paper on the door. He desperately tried to

convince her.

That there was no assailant here. And that there were only—two victims here.

Upon that—as Basara's explanation worked, the girl relaxed her body soon

enough. "Ehm...I take it that you understand now?"

On his question, the girl gave back a nod. When Basara timidly removed his

hand, the girl corrected her posture and laughed a 'Fufu'. A bright smile that

seemed like a proof of friendship.

Good. Apparently his sincerity was conveyed and she comprehended the

situation calmly. Hooked on, Basara also showed a smile with "Haha…"

—At that moment, he received an attack to the cheek and was blown off to

the side.

It was a slap. Needless to say, the initiator defect door was unlocked. Basara

bumped into the door and tumbled outside. There, he fell on his backside.

"Wh-Why…?"

"…Come again?"

While pressing on his cheek, Basara looked up dumbfounded. The girl had

twitched the edges of her mouth.

"First you peek on a girl in the toilet, then you get inside, cover her mouth

and try to make excuses… Put a hand on your heart and think well about

what you have done—in the other world."

As if to give Basara the finishing blow, the girl raised her leg and it was then.

"—Hmm? What are you two doing there?"

That a familiar voice sounded from the side. He had probably come to check

up on Basara as he was late.

Jin had come to the toilet at some point in time.

"Dad…" "Jin-san…"

Basara and the girl called out to Jin at the same time, then looked at each

other with an, ""Eh?"".

And then—as Basara returned to his seat, now two girls sat in front of him.

The taller one was Naruse Mio. The shorter one Naruse Maria. Like Basara

had imagined, the two of them were sisters. When they finished ordering

drinks,

"Ahaha, sorry, Basara-san."

Maria showed a friendly smile.

"We properly told the waitress that we are meeting up with someone. But

apparently, the one who guided us to the table didn't know about you two."

In other words, the shop assistants didn't speak with each other. It was an

elementary mistake.

The puzzle had been solved. However, it didn't necessarily solve the

'problem' as well.

"..."

In contrast to the smiling Maria, Mio was puckering her lips wordless for a

while now.

...Well, understandable.

To tell her to brighten up when someone interrupted her on the toilet earlier,

would be asking too much. It left the worst first impression at the important

meeting for the two remarrying families.

The remarriage wouldn't be cancelled because of this, but——Basara once

again checked upon the expressions of Mio and Maria, who sat in front of

him. And he thought,

…Still, they're cute.

Not the appearance alone, but their aura and casual behaviour made him

excited. Specially Mio, who apparently was also a first year in high school

just like Basara, albeit with a later birthday. In other words, right now, when

their parents hadn't remarried yet, she simply was a girl of the same age as

him. Of course that accelerated his heartbeat. Then,

"—But, I'm glad that you're a nice person, Basara-san."

Maria, sitting diagonally opposite to him, faced him and laughed with an

'Ehehe'. She looked very young for a girl only one year younger than Basara

and Mio and in her third year of middle school. Her cuteness stimulated a

boy's protective instincts gravely.

"As a boy of your age, I was worried about what to do when you were a guy

sharp like a knife."

"Ha, Haha…"

An age where you were sharp like a knife, just what kind of age was that?

The one of a national reaction entertainer?

[2]

"No need to worry. I mean, he seems to fancy a cute little sister."

"Seems so. I mean, he came into the toilet occupied by a girl."

On Jin's light joke, Mio in front sent off a cold glare.

"I said, that was a misunderstanding, an accident. How often do---"

"Hmp, still making excuses?"

When Basara declared with a sigh, Mio bended slightly forward.

A distance that made his heart skip a beat unmeant. She looked at him with

superb upturned eyes that emphasized their height difference.

"…..I'm sorry."

So weak. When Basara, unable to endure her destructive force, apologized,

Mio nodded "Mm, I forgive you" satisfied and finally brightened up her

expression. Basara made a sigh of relief.

"Oh right… ehm, excuse me, there's something I want to ask."

There Basara suddenly spoke out a simple question.

"Where's your mother? Will she come later?"

The prospect of getting a little sister, and even these two cute ones, had

surprised him.

But well. Jin never had said that it would only be one.

However, their mother, who Jin was going to marry, was absent, which made

this meeting pointless.

"Yeah, reminds me, I didn't tell you…"

Jin said.

"Their mother--- Chihaya-san is currently overseas for her work."

"...…Huh?"

Wait a moment. What did his father said just now? As bad as it sounded, the

marriage partner was currently overseas?

"…. Aw… Dad, lend me your ear for a sec."

Grabbing Jin's arm, Basara moved to a place where their voices wouldn't

reach Mio and Maria--- to the corner of the passage.

"…Sorry, but can you say that again?"

Basara crossed his arms and tapped with the index finger of his right hand on

his left upper arm.

"Mh? 'Hey---You said, that you wanted a little sister, right?' That one?"

"How far are you going back! I meant about the stuff about your marriage

partner being overseas!"

"So you heard it after all. So, what about it?"

"It's weird! That on a meeting for a remarriage, she herself wouldn't show

up!"

Even more so, when they were the ones that wanted to meet as soon as

possible. He wasn't going to blame her about going on a business trip, but a

meeting without her was pointless. Actually,

"I hope I'm wrong, but… you're not getting tricked, are you?"

"Haha. No, don't worry. Besides, do you really think I could be tricked?"

Certainly. If anything, he was the type to trick. This phony father.

"But--- then we could just have done the meeting once she came back…."

"I'm afraid there's a reason as to why we better hurry up."

Jin changed his expression from a smile into a serious one.

"Basara… Now that you saw these two, what do you think?"

"What are you asking… Well, cute, I guess."

At any rate, he thought they were some kind of idols when he saw them at

first. So…

…A reason as to why to hurry up, huh…

Judging by the conversation, Basara finally came to understand that reason.

The prospect of remarriage meant that they were a family of just mother and

daughters. And that mother was currently overseas on a long time business

trip.

"I'm sure, a parent would worry, if these two are all left by themselves… Is

that why?"

"Yeah. Actually, the two of them seem to be under the attack of some

suspicious person. To begin with, when I first met them at the city, a weird

guy was picking on them. Besides, there also seems to be a persistent

stalker."

"For real…"

The world sure was dangerous, but to think there were actual casualties. It

certainly was a pressing matter. The police didn't interfere with personal

matters. They wouldn't move unless something happened, which would be

too late then.

"I heard that Maria-chan stopped going to school, because of that stalker.

Those who want to go to school should just do so, but for someone who can't,

it's painful. Even if she's smiling so brightly right now."

Jin said.

"Well, for these reasons, I would like us to start living together already, if you

have no objections. They also say a remarriage is more likely to work out if

you know each other better beforehand."

"You mean to temporarily take care of them and see if it's possible to live

together as a family?"

"This is some kind of destiny. If we can protect them, then you would like to,

right?"

On Jin's words, Basara fell silent. It was a silence of affirmation. And-

…Mh?

Suddenly he made eye-contact with Mio on the other side. Like the earlier

forceful attitude had been a lie, she had a worried expression. Basara

narrowed his eyes and asked Jin besides him.

"---For how long?"

"For starters, a year. It might turn out we're totally unsuited to live together or

reach a conclusion about the remarriage, but--- They will only get back to

living alone, once a certain level of their safety is guaranteed. After hearing

all this, I wouldn't be able to sleep anymore later when I know that something

happened to them."

He had a point. When their mother comes back in a year and it was time to

decide about the remarriage, it would all fall apart if something had happened

to Mio or Maria.

More importantly--- Basara himself didn't want Mio or Maria to suffer.

"But where are we going to live? Our house doesn't have any rooms to

spare."

"We'll rent a suitable one. I already have my eyes on one. We should create

an environment as close as possible to a family, since we're trying to find out

if we're compatible. And it'll quicken things if we actually do get married."

"…Do these two know about the living together?"

"Yeah. They would gladly do so, if you agree."

On Jin's words, Basara stayed quiet for a while. But, soon enough he

mumbled slowly.

"...Okay. It's something you decided, Dad. So I'm fine with it."

He wasn't really casual about it. It was his true feelings.

"I see. Sorry for not telling you anything and proceeding on my own."

"It's fine. You must have your reasons for doing so."

He should just tell him everything once he was able to.

He and Jin were blood-related child and father, but their trust in each other

was far beyond just that.

Ever since the time when Basara had caused that problem--- the time when

he threw away everything to protect him.

"Let's get back, Dad… Or they will worry."

Saying so, Basara returned to their table with Jin. When they sat down on

their seats,

"…Uh- Uhm,"

with a timidly tone, Maria tried to confirm their state of affairs.

"Ah, sorry… Just some talk amongst men."

"He made such a serious face that I wondered what it's going to be about, but

then he said 'These two are so cute that I can't suppress my arousal'. Geez,

boys in their puberty sure are horny."

"Hahaha. Dad, that will have an afterpiece."

An afterpiece about fists at night. Just with him and his father.

And then, to Mio, who looked just as worried as Maria,

"I was surprised by all the stuff I heard yesterday… But, it's all right now."

Basara said.

"Until your mother gets back and even though we still don't know if the

remarriage will work out… I think it's a good idea to try out living together as

a family before instead of just suddenly remarrying. Let's slowly get to know

more about each other."

"…Really?"

Mio asked uneasily, whereupon Basara nodded with a "Yeah."

"We're a men's household, so having girls around really helps… Right, Dad?"

"Right. Besides, I always wanted a cute daughter. Basara also pestered me

forever about wanting a little sister. So don't show any reservation, you two."

"Thank you." "Yay, please take good care of us."

Mio and Maria quickly lowered their heads. And then-

"Well then, take care of me, Basara-kun."

Raising her head, Mio gave him a smirking smiling face.

"But--- if you happened to come into the toilet again, I'll kill you a hundred

times then."

"...Yes."

Her eyes were serious. When Basara's expression stiffened up, Jin said

summing up.

"Okay then…. let's get along as family from now on."

This declaration made with a smile, was the beginning of a new life-style.

"Issues might arise, but--- let's become happy together."

Therefore--- even though prospects for a grim future hang somewhat in the

air, it still felt peaceful.

Same for Toujou Basara's every day life----and for the world.
