Sakai──no, as a thank you to Maou for saving Amana-chan, I decided to call her by her first name, which I had been calling her by her last name until now.
　Since I had always called her by her last name, I was strangely nervous to call her by her name again.

　How many times can you say that guy from Saniya........

　At any rate, even though I asked him if it's okay to do that, Marao is all about this.
　She looks uncomfortable when Miya calls her, but she looks happy when I call her, so I don't know what women are thinking.

　This is why you can't get a girlfriend, but... well, as long as you're happy with yourself, it's fine.

　When I contacted Kurone with these thoughts, it seems that she was shopping for Amana-chan, and she's finished that too.
　Or rather, there was some very interesting information at the end of the sentence called 'Amana-chan's apron'.
　I can't wait to see it, but I can't bear to disparage Maou for it.

　The message from Kurone also said that I could come slowly to the meeting place, and I walked along while chatting with Mao.

　And so I arrived at the meeting place, where I found Kuroone-and Amana-chan with a bag that must have contained the things I bought.

　When Amana-chan sees me, she waves her hand out in a big gesture, as if to show off the vitality hidden in her small body.　
　Cute.

'Onii-san!'
Amana-chan, I'm glad you're feeling better this time.
One of the girls was helping me with my mana.

　He tells me why with a look of real happiness, but I'm very jealous.
　But even if I held her hand like a black sound, it's obvious that she'd have to choose between parent and child or a suspicious person, so I quiet my envy and jealousy quietly.

''I won't make a second attempt.
'It's not that I don't trust the black sound. Thanks.
Hmm. You're welcome.

　Hearing the words of thanks, Kuroon returned with a cheeky response with a bit of tongue.
　You're happy, but you're not honest.....

''So?　Was he able to thank Sakai-san properly?
Oh. Well, you were supposed to call me by my first name but what's with that smirk on your face?

　For some reason, Kuroone-she just answered normally, but for some reason, Kuroone-she started to give a warm, lukewarm look.
　A sense of regret is drifting in the air, despite the fact that she is such a beautiful girl.

''Betsy~?　I'm glad to see you've gotten a little closer~?
Oh, um, Kurone?　I don't want you to tease me too much...?
I'm sorry, Mr. Sakai. But can I talk to you for a second?

　When Kuroone-who was saying and doing things in an agitated manner-Mao, who was red-faced, called out for restraint.
　At the sight of this, Kuroone-sense immediately uttered words of apology, but continued to pull away from Mao's hand and move away.

''......... .........
"....!　..........

　Because of the distance and I'm not a hell-eared person, I can't hear the conversation at all.
　However, Marao is returning to Kuroone-s comments while blushing every single time.
　What on earth is my sister talking to her colleague about?

　If it's my black history or something, I'm confident I'm going to strike out of work.
　As soon as I do, though, I'm going to lose my place in the Umineko Transport.

Onii-san?　I almost squeaked by Kyu, but are you OK?
'Oh, yeah. It's not as bad as you're worried about, Amana-chan.

　I'm devastated by the state of society that literally treats anyone who is out of line with the group as a boil, and Amana-chan, as angelic as ever, calls out to me.
　I'm not good at this, I'll be scolded by Amagashi if I do something that would cause her to worry.
　While I was regaining my composure, their conversation seemed to be over, and while Kuroone-she seemed to be having a lot of fun, I felt that Marao's expression was somewhat contrasting, with a glimpse of fatigue on her face.

　What did I really talk about........
　A mental image of near dismay came to mind.

''It seems Kurone teased you quite a bit, are you okay, Maao?
'What?　Yeah, well I've got a reassuring ally rather than being teased, but I don't have a problem with it anyway.
'I see. Feel free to let me know if there's anything I can do to embarrass you, okay?　As your brother, I'm going to scold you as a colleague of Mao's.
Yeah, thanks.

　I tried to say a few words of encouragement to Mao, whose bewilderment hadn't cooled down, but for some reason, she gave me a look that included a look of dismay.
　I don't understand.
　Anyway, it's a good time to dismiss the group.　

Maou. Once again, thank you for finding Amana-chan today.
It just so happened, and you don't have to be so awed.
'But it's true that if it wasn't for Sakai-san, who knows Aniki, I wouldn't have been able to thank him so much. Thank you on my end as well.

　To the humble Mao, the black sound adds more gratitude to the humble Mao.
　And if this guy was right, if it wasn't Maou, it would have most likely been just words and yes goodbye.

'Thank you for saving Amana, onee-san!
Well, you're welcome.

　And to Amana-chan's genuine words of thanks, Mao also replied honestly without showing any modesty.
　I should also thank her the day after tomorrow, when we meet at work.
　While secretly thinking that, we parted from Mao.

　===.

Aniki. Look at me.
Hmm?

　I was waiting for a traffic light when I was waiting for a traffic light and was approached by a black sound in the back seat.
　As I turned my face back as I was told........

"...

　Amana-chan, who was cheerfully talking to her sister earlier, is sleeping soundly.
　Her usual innocent smile is good, but seeing her innocent sleeping face like this makes me feel more juvenile.

We walked and talked a lot today, and I'm sure she's tired.
Yeah. Let's give them some privacy until we get home.
Yeah. Oh, but I'll just take a quick one.

　Hey, what the hell are you doing taking pictures of a little girl's sleeping face?
　It's true that she's cute enough to want to save a picture of, but there are limits to what she can do!
　Well, that's it.

"Black sound. Can you send me a picture of that later?
What are you going to do with it?

　Why do you give your brother such a quizzical look?　

"Even on days when you can't see Amana-chan, I thought it would be soothing to see her sleeping face.
Well, there's no way that's a good idea.　No, no, no, I don't want to be soothed by looking at a little girl's sleeping face on my phone, and I don't want to be a donkey!
Hey, be quiet. You'll wake up Amana-chan.
'Don't make it sound like it's my fault!

　Even though I replied with a perfectly sound mind, Black Sound didn't send me the photos for what I didn't agree with.
　Finally, we managed to negotiate a deal to rent a room for the summer vacation as well, and he reluctantly sent it to me.

'Okay, we're at the apartment.'
Bye, guys. We're here, Amana-chan.
Hmm...　Whew........

　We made it home safely, and Amana woke up with a really cute absent-mindedness when Kuroon woke her up.
　I get out of the car with my luggage and open the door of room 201 that I'm renting.

'I'm home~!
What?

　Then Amana-chan started to greet me to come home with a cheerful voice sound that I couldn't believe she was getting out of bed.
　It was so sudden and unexpected that I couldn't hide my surprise and said it out loud.

　Noticing my reaction, Amana-chan looks at me with an expression that doesn't question her words.

''Ah, Amana-chan?　This isn't just a house for Amana-chan...
"?　But when I get back from my outing, I have to say I'm home!
..........

　I can't find the words to reply to his stagnant and straightforward argument.
　While I was at a loss for an answer, Black Sound, who was similarly letting loose, suddenly erupted.

'Hahaha, yes, yes. You're right. I'm home~

　I say 'I'm home' with a smile on my face.

'See, Onii-san too!
Yeah, I'm home.

　Then, at Amana's urging, I said the greeting to come home.　
　It's nothing out of the ordinary, just an ordinary greeting.
　Especially since I've been living on my own, I've gradually stopped saying it.

　The natural behavior of the girl who's staying with me for three days only made me aware of that fact once again.

　When Amana-chan heard my words, she smiled with satisfaction and....

''──Welcome back!　Heh.

　It was in this apartment, where I had come back many times, that I heard the word 'welcome home' for the first time.
