What do you mean my cute disciples are Yanderes?
chapter-1236

(MC POV)

Ok, I know her naming sense has never been great but did she really have to call it that of all things?

Thank everything that I don't need to worry about the existence of this thing being spread anywhere else since this universe I created would be isolated here.

"Wahahahaha!! What do you think, Onii-sama? It's perfect isn't it?!"

I looked up at the giant mecha that Elaria most definitely used her divinity to create a few moments ago.

"I've seen it during the battle royale earlier, if you forgot," I reminded her.

"Ah! But this one is much better! It's made of a stronger material, it has more weapons, moves faster and I made the likeness more similar to Onii-sama!!"

Sure enough, the head of the mech had more defined features than the previous one where it just had a really basic head shape.

I turned to my little sister, "Ok… Ummm… I'm just going to say this before we start… But we're actually on a time limit here so if this campaign takes longer than two days, we'll have to go back home once the time is up."

"Ehhh? Why, Onii-sama?"

"Did you forget that the others are also waiting for their turn to go on a date too?"

"Doesn't Onii-sama pause time for the rest of the Universe while we are here?"

"I don't… Otherwise why do you think I would take a few days before coming back?"

"Ehhh… But why wouldn't you, Onii-sama? Wouldn't it be better if we just pause time and enjoy ourselves?"

I gave her a wry smile, "Well… If I did, I'd think that quite a number of you would be content to just stay like this for several years before going back. Maybe you might not even want to go back at all?"

"Unn… That is true I suppose… I guess we'll have to destroy all of them in two days then! Leave it to me, Onii-sama!!"

Eh? Unless we're using our powers again, I don't think we would be able to destroy all of them in just two days…

Can we?

You know what, I actually think with Elaria, something like this was actually possible… Considering we did eradicate the Inktyr Republic in one day and that was just us taking our own sweet time.

If she were to just create an entire fleet of this mech alone and send them out, that would be possible… But was this what she wanted to do? I'm sure she wanted to be in the cockpit to watch the planets and ships get blown up, wouldn't she?

She pointed at the mech happily, "Alright then! Let's go, Onii-sama!"

We had to teleport ourselves into the cockpit since Elaria did not create a platform or scaffolding for us to climb into the mech.

She even designed the cockpit to be more of a room than an actual cockpit. There was even a coffee maker by the side and a fully stocked fridge…

And despite all that, there was only one seat again.

I already knew what she was expecting from me so I took my place on the seat without saying anything. Elaria let out a yelp of glee before settling herself on my lap.

She stretched out her hand and multiple holographic screens appeared around her while the walls became transparent, displaying the view outside with full clarity.

That was when I noticed something was missing.

"Where are the controls?" I asked.

Elaria looked confused at my question before letting out a gasp, "Oh!! I forgot about that! Ummm… Let me just… There we go!"

Two sticks made out of pure light appeared in her hands.

She really forgot to create a way to control the mech…

"Alright!! Let's go!!"

At first, I thought we would start flying into the air, but instead, the mech directly teleported itself into space.

It wasn't a random teleportation either, since the place we appeared in had a planet that was surrounded by a horde of warships of an alien design.

A screen materialised in front of us and a very surprised six eyed alien appeared on the screen.

With how he's dressed, I assume he's most likely the fleet Admiral or at least someone important around here.

"Greetings! We're from the Oni Empire! Time to die!!" Elaria greeted chirpily.

The mech we were piloting raised its hands and two beams of light shot out from its palms. Instead of travelling in a straight line, the light curved and bent as though it was homing in on its targets, piercing through everything in its path.

Every ship that the light passed through was instantly vaporised, burning through shields and matter instantly.

One of the beams also hit the planet itself and it burned through the planet too, leaving a gaping hole at where the core of the planet should have been. The surface of the planet then spontaneously combusted, burning everything that had been on it into ash.

It held for a moment before the entire world crumbled into pieces, leaving nothing but the blackened shell of the planet behind.

Elaria seemed to have intentionally left only the ship with that six eyed alien intact as a lone ship floated awkwardly amongst the debris.

Shewaved at the screen where it showed the alien looking around with wide eyes fear, "Hope you enjoyed our greeting! Here's a present for you!"

She moved one of the sticks in a pattern and a missile shot out from our mech's shoulder, hitting the back of their ship and destroying their engines while leaving the rest of the ship intact.

"Ok, bye!"

Elaria pressed another button and our location shifted again, this time to another part of space that belonged to the same faction.

Just like before, another screen materialised in front of us with a similar looking alien on the screen, although this one looked like it was naked and also in the middle of a shower as well.

"Oh hello! It's me, Shogun of the Oni Empire!! Time to die!!"

This time the beams of light were shot from the mech's eyes instead, cutting apart all the ships and stationary defences that had been around us like hot knife through butter.

The planet itself was not spared either as the laser cut the world and its moons into two.

There was a split second of silence before everything that had been cut by the light exploded including the planet itself.

This time, the screen fizzled out into static as the alien in the screen was killed alongside everything else.

Elaria tapped her chin, "Oh, that guy must be a senator on the planet or something. Oh well, moving on!"

We teleported again just for Elaria to repeat everything in the next location, which led to me questioning why she was doing it like this. More specifically, simply rushing around to destroy everything.

She tilted her head at me, "Eh? Of course I have to do it fast, Onii-sama, or else I won't be able to destroy this entire galaxy in two days!"

I coughed, "You know… When we leave here, the flow of time for this place is suspended right? That means we can just enjoy ourselves casually and leave once the time is up and come back to the same exact point whenever we want later…"

A figurative light bulb seemed to go off inside Elaria's head, "Ohhh! That's genius, Onii-sama! Then we can enjoy a casual destruction of the galaxy! This is great!! Onii-sama is a genius!!"

Only you would call the destruction of the galaxy as something casual… And didn't I mention this before? I guess I didn't… My bad.
