A Heroine who connects to a Collar and is confined in the Basement

"Azusa is not spoiled by Onii-chan. You misunderstand me a little, Shimotsuki-san!"

 

"Why are you getting so worked up about it? It doesn't matter. A sister lives to be spoiled by her brother, so there's nothing to be ashamed of. Oh, I envy you...... And by the way, Kotaro-kun? I'm going to be your little sister now, so take care of me, okay?"

 

I don't want to be flattered.

Well, Shiho is a bit of a weakling, but she's the type of person who gets a little carried away with people she lets her mind wander, so even if I told her I didn't want to, she wouldn't be convinced.

 

Yeah, so I guess I don't have a choice.

 

"Azusa, I'll accompany you for a bit. Shiho, no offense, either."

 

"You're too soft on her! Look at that smug look on her face! Stop making that face, it's disgusting!"

 

"Uh-huh. I'm sorry to hear that, Kotaro-kun is on my side no matter what. I'm going to be your little sister like that, okay? Azusa-nyan, is your position ......? Well, what do you say in a situation like this?"

 

 

Maybe 'threatened'?

It seems like she's trying to force herself to use difficult words and is not quite sure what she wants to say.

 

"Anyway! That's why, from now on, I am Kotaro-kun's younger sister♪. I want you to call me by my nickname like my family. Shi-chan."

 

"Yeah, nice meeting you....... Shi-chan?"

 

..... I'm kind of embarrassed.

But Shiho is very pleased with herself.

She sat down next to Azusa, laughing happily.

 

"Kotaro Onii-chan, please clean my ears."

 

And the demands are too hard from the very first move.

 

"Wait a minute! My sister wouldn't do that! I don't want people to get the wrong idea that my sister is this kind of creature."

 

"Well, is that so? I always thought we would be doing this all the time....... What a pity. I imagined a life of snuggling at night, waking up together in the morning, sitting on your lap during the day, and being spoiled all the time."

 

"...... That's not true, shh, shh, shh, shh, shh. Hey, Onii-chan!?"

 

Hmmm.

Azusa, looking a little impatient, asked me to agree.

It's true that such things don't happen these days, though.

Thinking back to my junior high school days, I felt that Shiho's fantasy was not far off the mark.

 

"......You know, a few years ago, we slept together."

 

I am not good at lying, so I told the truth.

When I did so, Azusa's face turned bright red, and then Shiho looked pale.

 

"No, no, no. At that time, I was young, or rather, I was just a child, but I had no other intention."

 

"That's not fair. I had never been cuddled before either, but I guess she was taking advantage of her position as a younger sister to get all the spoils! No, he's my personal treasure, and you can't touch him anytime in the past, present, or future."

 

Jealous of past deeds too? ...... Well, I can't help it. Shiho is just being affectionate, so let's give up.

 

"I want to be your only sister. I will be your sister, Kotaro-kun, so you don't have to worry. I'm sure I can make the most of my sisterhood better than she can."

 

"....... Onii-chan, she's absolutely crazy! As a family member, let me tell you, you probably shouldn't get married or anything...... Onii-chan, one day you'll be locked up in a basement with a collar!"

 

That's not true - and the fact that I can't say that is also a charm of Shiho.

If that happens, well, ...... yeah. It's just that it can't be helped.

 

"Then it will happen."

 

"I knew you were too soft on her! Azusa doesn't like it!  I don't want to see Onii-chan killed because he was loved so much that he turned into a skeleton!"

 

"Ufufu. I'm so happy to hear that. I think I can love you to the bone, Kotaro-kun."

 

"Look! You heard that, right! She's definitely going to make a mistake someday. Azusa warned you, right? I don't know you two anymore, okay?"

 

--And so it has been since the summer break.

Shiho and Azusa are somehow able to communicate with each other, or ...... they are so open to each other that they can complain without hesitation to each other.

 

Thanks to this, Azusa has recovered enough to be able to speak out loud like she does now.

 

To be honest......, right after the overnight learning program ......, it was so painful that I couldn't even look at her, so compared to that time, Azusa is so much brighter now.

 

After all, as her older brother, I want this girl to be happy.

Although I was once cut off, I couldn't hate her enough to cut her off as a brother and sister.

 

Whether that is right or wrong, I still can't give an answer to that question.

But one thing I could say was that I was glad to see Azusa back on her feet again...
