Our house is a ten-year-old single-family home built in a concession in a residential neighborhood a little further from downtown. I can still miss the tension in my newly built home when I was in first grade.

The interval is 4 LDK, with the living room and guest room on the ground floor, the parents' room and sister's room on the second floor, and my room.

How many men live in this house were my father, my mother Yukiko, one younger sister Yuna, and then my four? I've been to different worlds, so the status quo should be three.

Most of the time, my dad was flying around overseas at work and he wasn't home.

For the first time in a year, my home was reassured first, almost as I remember it.

When it came to the difference between the eyes, the paper of the faded searcher was affixed to the block walls. The sticker had my name and features on it, and then my mother's mobile number, and my chest ached when I found out that I was worried about my family for a long time.

And the other thing that had changed was the intercom, which became a monitored object.

I press the call button on the intercom.

... I hope someone is here.

"... Yes, who is it?

The person who answered was my sister Yuna.

The voice was quite surprising.

I can't do it if I'm what I am. You should think he just wasn't staying.

"I know where your brother is. Can I talk to you for a second?

"……… Religion is on time."

I was cautious. I've heard stories of religious solicitations coming to houses where misfortunes have occurred. There must be a lot of stories like this.

... I have no choice, let's use my wife's hands.

"I heard an interesting story from your brother...... On a summer night in sixth grade, you couldn't sleep with a sudden thunder you visited your brother's room. And you couldn't go to the bathroom with ringing thunder..."

When I told her about my sister's biggest black history, which I only know, there were signs of her voice trembling across the intercom.

"Hey!? Wait a minute!

The front door opened with momentum when the noise of turning around was heard from inside the house. It was Yuna in my high school uniform who came out of there.

"…… In the meantime, come inside"

It was the living room on the ground floor that was put through. Looks like my parents aren't here to see my front door shoes. It's careless of you to give a stranger a home without family, sister, but if you look like me now, you can't help but relax your guard.

"This is Mr. Ikto's house, isn't it?"

I haven't heard Alicia in a long time. By the way, we've been awkward and silent with each other since the bathroom earlier.

And I miss it......

The living room placement hasn't changed much since I left last year... enough to say that my lower vision is the discomfort I feel the most.

"Oh. And in front of me is my sister Yuna."

The last time I was in junior high school, Yuna had a slightly young impression that she was a soiled high school girl.

Her hair, which was dark to her shoulders, grew slightly brighter brown with stretches around her waist.

The height, which was about the average for women, had also grown by nearly 10 cm, and the legs stretching out of the uniform skirt were much longer and supple.

There seems to be somewhere out there as my body grows, and my sister has a good style.

"Is this man Mr. Yuna? She's younger than me... '

By contrast, I, Alicia, who should be a year older, have the perfect toddler shape to go through even in elementary school, so I guess there's something to think about.

"… Alicia will grow up soon."

"Mr. Ikto. I'll tell you what, it's not human resources at all, is it?

Yuna prompted me to sit at the dining table. The seat surface was high and I couldn't sit without jumping. I'm not comfortable with my legs hanging out on the floor at all.

Yuna sat across from me across from the dining table and observed me dressed in cosplay like a frigid.

"… so what do you know"

"I was only in elementary school, and I don't think you have to worry about me being scared of thunder and taking a leak, okay?

"Why did you do that......!? Brother, you promised me you wouldn't tell anyone......!

... You look amazing, sister.

"He said if I told someone, he would kill your brother and I would kill myself too, I wonder if your brother forgot...... hey? You said you knew where your brother was..."

It's time to figure out the misunderstandings. First of all, yes.

Or what are you going to do when you hear about your brother's whereabouts!?

"There seems to be a misunderstanding, but your brother didn't divulge any secrets."

"... Huh? Then why...?

"'Cause there's a couple of me."

Yuna hardens into my words.

"... no, no, no, that's crazy. That's How can I be your brother? [M] You're lying to me, Ole Ole Scam."

Well, I guess so.

In the opposite position, I would think the same.

"Then you should ask what only your brother knows. Then you can believe it, right?

"... Okay. What's your brother's favorite food?

"Hamburg."

"Then..."

Then the question pops up early in the arrow succession, and I answer it. There was also a mix of hooking issues inside that I couldn't possibly know about, and I sighed at my sister's intransigence. I don't know what my sister's three sizes are, I...

"……… Where and with whom did you go on your junior high school graduation trip?

"A night or two at the Hot Springs Inn, which Ethereal and Emerald and your four relatives do. It was really a plan for the three of us to go together, but you had no choice but to go with the four of us because you cheat and cry... even though you had nothing to do with graduation"

"……… I can't cry."

"Well, that's good. It was fun for all of us to go. We haven't had a chance to do anything together since then..."

And as soon as I got into high school, I was summoned to another world.

"Are you sure, brother......?

With this, Leo will be able to establish himself as the fourth faction in the current three-ways succession war.

"What have you been doing for a year? My dad, my mom, me, everybody, I was so worried. Besides, why are you looking like that...?

"It's gonna be a long story, and I think it's gonna be an unbelievable story, okay?

"Yeah… let me hear it all."

Then I explained after I fell off the ferry on a school trip.

About the other world, and about me and Alicia.

"Oh well... then I guess I'm really your brother..."

"...... you believe me?

"I wonder if I have to believe more than I have a real thing in front of me... I'm a complete brother to the way you talk and the habits you have when you do something"

When I look back calmly, I think it's absurd as I am.

... It's good to keep Yona dyed in fantasy and reincarnated comics and cartoons.

"Whatever... Welcome back, brother"

Soon there were tears in Yuna's eyes.

Feeling the familiarity that was always directed at me, my brother, by that gaze, I finally got the feeling that I was back at my house.

"... Ooh, I'm home, Yuna"
