Hmm....Amana-chan's mother asked you to take care of her?

　Once we regained our composure, we revealed to Kuro-One in the room not only the reason why Amana was home, but also the whole story of how it all came to be.

　I asked Amana if there were any lies along the way, but since I only told the truth, there was no such thing as a lie.
　I'm sure that Amana is the most honest person in the world to encourage me to talk, so the conversation went on smoothly and without complications.

　After listening to the whole story, Kuroon's reaction is one of doubt and suspicion.

"You still doubt me.....
It's my fault for being so careless, but I think it's also my fault for trying to hide it.　You just said you're usually keeping the kids of someone you know, and now you're getting more suspicious as a result of your deception, right?
Ggh.....

　I could barely let out a gagging sound because I knew it was true if the black sound told me so.

It's a good idea to hide it, considering that you'll be treated like a pedophile if you flaunt it.
''Yes... so you're going to stay here after all, Black Sound?''
Mochi. I'm here with that intention in mind, so it's only natural.　There's no way I'm going to stop you just because there's a girl I wasn't expecting.
Huh, well, I've got a futon, you can stay the night.
Yes!

　After getting permission to stay the night from me, Kuroone-sensei strikes a gut pose and lets out an overtly happy smile.

"You're going to stay in the same room?
That's right~

　During the explanation, Amana-chan missed Kurone and began to call her 'onee-chan'.
　Kuroone-san also seems to have forgiven Amana-chan, who smiles carefree, and her tone is a bit soft.

　The word "Amana-chan" can only be used to describe this.

　As I was admiring that, Kurone stood up.

I've received your permission, so let's get started. Aniki, can I take a look at the refrigerator?
Oh. Otherwise, there's no point in letting him stay.
You're renting your own bedroom, of course you're going to do this.
"?　What are you going to do, Onii-san?

　The brother-sister relationship between me and Kurone was established without words, but there was no way Amana could understand that.
　She has a questioning look on her face, and I tell her what Kuroone-san is trying to do.　

'Kurone is going to make me dinner,'
'Wow!　Can you go all the way down, oneechan?　Amazing!
''Hmmm... You can praise me more! Some animator says it's a substitute for rent, but as far as the taste is concerned, you can count on it!

　Otherwise, there's no benefit to staying even if you're my sister, and I'll return to the black-toned complaint that was casually vented to me in my mind.
　But it's true that the food that Kurone makes helps me.

　It's a good thing that you can't get away with it.
　So the food lined up at my parents' house tonight will be my mother's.
　And unfortunately, my mother's housekeeping skills are inherited by me.

'Onee-chan, that's neat,'
'Didn't I once show you a picture of a black sound in your homework when you looked at everyone's homework?　He said the same thing then.
'Oh!　Come to think of it, I've seen it before!

　Amana, who seemed to be convinced by the vague sense of déjà vu that she was feeling, made a surprised expression on her face.
　Cute.
　Well, it was only once, and even smart Amana-chan can't help but forget about it.

'How old are you, Onee-chan?'
I'm a freshman in high school and I haven't had a birthday yet, so I'm fifteen.
Hey, you're six now, so you're nine up!
''That's right. It'll take another nine years for Amana-chan to be the same age as Kuroone-chan now.
Mmmm.........I can't wait to be a grown up.......

　Amana muttered in frustration at the age difference between her and Kurone.

　From Amana-chan's point of view, who has only been in elementary school for two months, the first year of high school, Kurone must look like an adult.
　Even if she didn't, with Amari, a true female role model, around her, it wouldn't be surprising if she longed to become an adult as soon as possible.

　In the meantime, the food seems to be ready, and the apron-clad Kuroon sets the meal on the table.
　What my sister made as tonight's dinner was stir-fried vegetables.
　The white rice is something you heat up in the microwave to save time, but I think the simplicity of the dish makes it easy to notice the difference in flavor.

　Amana-chan sat next to me and Kuro-One sat down in front of her.
　In an effort to quickly satisfy this hunger, we began to eat.

''Itadakimasu!''

　I put the bean sprouts and cabbage between them with chopsticks and bring them to my mouth to chew.
　The flavor of the vegetables and the pepper tossed in the frying process is delicious.

　Even if your taste buds have been completely enriched by Amunashi's cooking, you are more than satisfied.

'As usual, on your front. You've improved your skills again, haven't you?
Yeah?　It's not going to be the same as usual.

　Her mouth is bare, but from the way her gaze is turned in the direction of the day after tomorrow, she's just hiding her happiness at receiving the compliment.

'O-nee-chan's ori-ri, yummy!
Oh, yeah?
'Yes!　It's just as awesome as my mom!
Hmmm... yeah, right...

　Ah, you look so happy.
　Amana-chan's straightforward praise had even Kuroone-she couldn't hide her embarrassment and was chewing with a grin.

　Not long after, the meal was over, and when I finished washing the dishes I used, I saw Amana and Kurone chatting with each other.

　The two beautiful girls, despite their different ages, laughing at each other in harmony is a sight to behold.

'I was thinking at the dinner, Amana-chan loves Aniki~'
'Yes!　I love it!

　And it's this doozy of a favor.
　Oh no.........I can't stop grinning.......

Do you like onee-chan?
Hmm, it's nothing out of the ordinary.

　In contrast to such Amana-chan, Kuroon's reply is very straightforward.

　Hmmm, if you say so, it can't be helped.

You can't be a liar. When you were little, you used to say things like, 'I'm going to marry my sister and her sister.

　Kurone Hayakawa, at the time, was four years old when he said this.
　She's a bit cocky now, but she used to be a superb big brother.

　At my coming out, Kurone's face instantly turns bright red.

''Gaaaahhhh!　Wait, what, how can you remember something so long ago, you f*cking animator!
The way you put it, you remembered it too...
"Oh, wait.........ah~.....

　There was no need to dig a grave........
　Kuroone-san, whose sense of shame was limited by her own gaffe, buries her face in the cushion beside her and shuts up.

''Ehehe, Onii-chan likes Onii-san a lot too~!
'What?　Ngaaaaah!

　And then Amana's pure and innocent impressions became a tome and she began to writhe and writhe on the spot....
