What do you mean my cute disciples are Yanderes?

(MC POV)

So… I ended up being dragged out of my room without a shirt on.

In case you were wondering, we're currently on Elaria's flagship travelling towards a nearby star system on the outer fringes of the galaxy.

Unfortunately, I'm more concerned about Elaria's mental state right now since she went to forcibly combine her two selves together like that…

"Elaria… Could you stop for a moment?"

"Hmmm? What's wrong, Onii-sama?"

"Well… I'm just a little concerned that you forcibly merged the two memories of yourself into one. You should not have done that…"

"Eh? What are you talking about, Onii-sama? What two versions of me?"

You see? Elaria now thinks that the two versions of her are one and the same person. That's definitely not a good thing at all.

"Elaria, are you a galactic dictator or a newly ascended goddess with the domain of 'Work'?"

My little sister tilted her head at me, "Hmm? Of course I am a galactic… Eh? No, no… I should have ascended that day… But… But I was also attending a ceremony that day too… I…"

I gave her a chop on her head which made her crouch down on the floor while grabbing her head in pain.

"Owwww!! What was that for, Onii-sama!"

"Are you feeling less confused now?"

"Confused? Eh? Oh right. We're here for our date. What happened?"

I helped her get back up on her feet, "Well… You tried to forcibly combine the memories of your two alternate selves together just so that you could one up Tsuki. Please don't do that again."

"Whoops~ Ehehehe~ But I did something that she didn't do right?"

"That doesn't make this any better, Elaria… Anyway, I can pause time for you to get used to the two memories you know? There's no need to rush at all if you want to take it slow."

"Kuh… That would be like admitting defeat! I won't accept that! I'll do it the normal way instead! Ah… But umm… Could we go somewhere private first?"

I raised an eyebrow, "We can… But why?"

"I want Onii-sama to hold me while I do it~"

Why is my little sister so cute? Of course I can do that~

In the end, I brought her back to our room and sat her down on my lap while she integrated this World's memories with her own.

She even made me do it while I was still half naked too.

It took her about two minutes before she managed to get her memories in place, though she still seemed a little out of it at the end.

It's not like one could just instantly adapt to living multiple lives so quickly after all, so only needing two minutes is already quite a feat.

"Unngghh… So I'm a galactic dictator in this universe and we're currently at war with some stupid aliens that think they were big enough to fight us… I don't care about that… What I want to know is Onii-sama is… Oh~ Onii-sama is still my Onii-sama! Then this place is perfect~"

Glad to see that the fact that we were at war or even the fact that she was a galactic dictator weren't points that were considered important to her, but whether or not I was her brother was a more important point of consideration…

Although… There is one thing about that she doesn't seem to realise yet but I guess I'll just let her find out about it herself later.

She leapt back up on her feet with her hands planted on her hips, "Alright! I'm ready, Onii-sama! Let's start our date!!"

I finally managed to put on a simple dress shirt before nodding at her, "I'm ready."

Instead of moving towards the exit, Elaria gave me a really confused look, "Eh? Is that all you're wearing, Onii-sama?"

I looked down at my shirt, "Yes? What else would you expect me to wear?"

She gestured to her own uniform, "You know, something like this? I was fully expecting Onii-sama to be wearing a uniform like mine too! You even wore one at Kiyo-- Err… I mean… Why aren't you wearing one?!"

I feel like she was about to mention me wearing a uniform with Kiyomi? Though I would question how she knew about that?

Deciding it didn't matter, I shook my head, "I don't wear one in this alternate World, Elaria."

"Ehhhh! That's so not fair!! Why don't you, Onii-sama? Do you not want to?"

"Mmm… Not exactly… It's more like I can't, you see. Anyway, we should really get going. You were expected on the bridge like half an hour ago. I don't think we should keep the staff waiting any longer."

She looked like she wanted to protest but she decided it could wait so the two of us made our way to the bridge. With our memories, we manage to get there without too much trouble.

"Shogun on the bridge!" Someone called out the moment we entered.

Ah, that's right. Elaria gave herself that title despite the fact that she's practically the Empress. But well, when you're at the top, you get to call yourself whatever you want.

She made her way towards the centre of the room before stopping suddenly.

Elaria then looked around the place as though she was searching for something and everyone was looking at her nervously, obviously a little concerned that she was doing something out of the norm for them.

My little sister then turned back to me, "Onii-sama? Where is my chair?"

I blinked at her, wondering if she was trying to joke around but the way she asked me told me she was serious. That's weird, did her memories not show her this?

I went ahead to point at the plush throne in the middle of the bridge that sat on an elevated platform, ensuring that everyone here would need to look up at the person seated on the throne to see them.

"Eh? Oh! I get it! What are you waiting for? Onii-sama? Come on!" She beckoned to me.

I went towards her and since I already knew what she wanted me to do, I didn't need to ask before I stepped up to the platform and sat down on that throne, causing almost everyone in the room to widen their eyes in surprise.

Several people in the room even let out a gasp of surprise at my action, though Elaria did not seem to notice it.

None of them had even remotely recovered from the surprise before Elaria turned and sat down on my lap.

"Wahaha! I can't believe the me of this world would do something so genius! Alright, what's the news?!"

For the first time within this World, no one actually answered Elaria's question as everyone was too shocked by what they've seen to say anything.

My little sister turned to look at me, "What's wrong with them, Onii-sama?"

Before I could answer, several of the guards below us suddenly rushed to surround us.

"Get away from the Shogun right this instant!"

"How dare you?! You're only just a brother!"

"The audacity!!"

"Get down from there right now!"

Welp, I guess now she should be able to know what's going on?

The two of us actually do not have a really good relationship in this universe, I'd thought she had seen that by now…
