“–n. Wake up, Asumi Onii san.”

“Fwuee !?”

She whispered in my ear and I woke up.

“Oh, you’re awake. Good morning, Onii san. Well, it’s still nighttime.”

“Eh? Huh? Aoi chan?”

When I woke up, what I saw in front of me was a girl wearing a middle school uniform.

Her expression did not move much, but she was a beautiful girl with lovely silver hair.

This girl’s name is Shinryuuji Aoi chan.

Rumor has it that she has an IQ of 300, and that she conducts suspicious experiments at night.

She is Akane san’s younger sister and the fifth daughter of the Shinryuuji family.

“Um, Aoi chan. Where am I?”

Scurrying around, I found myself in a place I didn’t know.

It’s like a luxury hotel room.

The bed was a single size, there was a sofa and other furniture, and there was what appeared to be a shower room.

Aoi chan looked at me with a stern gaze and tilted her head in a cute way.

“Don’t you remember?”

“Erm, I remember that Akane san took over my debt for me…….”

I went back to my memory and recalled what had happened just before I lost consciousness.

“Right, Akane san made me snort some kind of strange medicine.”

“Yes, a sleeping spray I made. And locked you up, Onii san.”

“Ah, that mysterious medicine. Did you make that, Aoi chan? That’s amazing. ……Eh? What did you just say?:

“You’re confined.”

Confined? Eh, confinement?

I repeated the same word in my head, puzzled.

“What does that mean……?”

“It means exactly what it says. Do you have any questions?”

“No, I only have questions ! Eh !? What do you mean by confinement !?”

“Confinement is [an act of restraining a person’s physical freedom and keeping him or her locked up in a certain place and not letting him or her out.] that’s about it.”

“I didn’t ask what the word means though !?”

The conversation was not engaging.

“Erm, why am I being locked up? If it’s the 5 million that Akane san paid, I’ll work part-time to pay her back, okay?”

“It’s not a matter of money. For now, I’ll remove the chains in Onii san’s hands and feet.”

“Eh? Whoa, you’re right.”

I realized after all this time that my hands and feet were bound with sturdy chains.

Apparently, I was forced to sit in a chair while being restrained.

Aoi chan carefully removed the chains one by one by sticking a key into the lock.

“Ah, I’m going to tell you first, you can’t run away.”

“……I won’t.”

“I’m glad to hear that. Okay, I removed the chain.”

I got up and ran as fast as I could toward the door that I thought was the exit.

Putting my hand on the doorknob, I was about to rush outside then–

“Ouuch !?”

The door didn’t open, probably because it was locked, and I hit the floor head first.


Aoi chan looks into my face, which has fallen to the floor, with quizzical eyes.

“I’m glad I locked the door just in case.”

“……What are you going to do to me?”

“I’m not doing anything. I, no, we just like you, Onii san.”


You like me? I mean, who are ‘we’?

“……I knew you didn’t notice. I appealed to you every time I saw you, but…… I’m a little shocked.”

“Um? Sorry?”

“I don’t need an apology. Anyway, we don’t mean any harm to you, Onii san.”


“Yes. We just want to take care of you. From morning to night, we’ll take care of everything.”

Her gaze didn’t change, but for some reason, Aoi chan’s straight eyes sent a chill down my spine.

No, let’s take comfort in the fact that there is no fear of harm now.

“Well then, I’ll leave you with this. Now all the sisters will go and decide who will be in charge of taking care of Onii san. It will only be for a short while, but goodbye.”

“I’m not a dog though……”

‘……True. I’m not going to call it “caretaking duty,” I’m going to call it caring for Onii san.”


I don’t think much has changed.

“Oh, and then.”


“I’m sure everyone will try to seduce you in any way they can…….”

Suddenly, Aoi chan whispered in my ear.

“You can’t get flustered with anyone other than me, okay♡”


“Fufu. Onii san, your ears are weak. I found a good weak point. I’m one step ahead of my other sisters. Well then.”

After saying this, Aoi chan left the room.

I put my hand on the doorknob again, but it was firmly locked.

It seemed impossible to get out of the room.

“Somehow, something terrible happened.”

Without panicking, I first checked my belongings.

My phone–not there.

Well, I’m locked up, of course they’re going to confiscate it.

I opened the closed curtains, hoping to escape out the window.

But my guess is off.

“The windows are locked. And it’s an iron bar. It’s too tight. Oh, I can see my house…….”

The view from the window was not much different from the one I knew so well.

The house I used to spend time in is in the distance, and I know that this is the inside of the mansion next to the house.

There is no way to contact the outside and there is nothing that could be an exit.

This appears to be a full-scale confinement.

“….Okay. There doesn’t seem to be anything I can do now, let’s sleep.”

Now I’m going to sleep and get a little bit of energy.

If there is a chance to get out of here, I want to be ready to take action immediately.

If I don’t get out of here, I feel like I’m going to be a useless person for some reason.

Fortunately, the TV seems to work, and I’m not completely cut off from outside information.

I’ll try to get information frequently and look for a chance to escape.

I decided to go to bed, cover myself with a blanket, and sleep.
