The Child in the Sword

No! You devil!
It's bad enough being dragged into another world by some strange girl.
No way I'm suddenly becoming a married man without knowing what's going on!
All responsibility and none of the fun? Hard pass!
I'm not a devil, Daddy! I'm Omega!
Omega's been asleep for sooo long! And waiting even longer!
Did Omega do great? Hmm? Omega's such a good daughter, right?
Then can Omega go outside now? Can Omega go play?
I'm telling you, I'm not your dad...!
...You're not?
That's weird... You smell just like Daddy...
The girl's face fell with a hint of disappointment.
I felt a twinge of guilt.
But... I really wasn't her dad...
Okay...
Guess Omega will just go back to sleep then.
Good night...
W-wait!
Where is this place?
Here? This is the Star Piercer. And Omega's home.
I'm inside the Star Piercer...?!
Yup! It's also called the database.
Oh? This is the first time Omega has seen anyone come in here.
That's so cool!
Database?
Yep!
Aren't there tons of books here?
More like... bundles of data than actual books...
Daddy made this for Omega to read! ...Probably.
So Omega wouldn't get bored while waiting.
But most of them are locked, so Omega can't actually read them...
Maybe they're just too old.
I see.
...So what were you doing here?
Well, about that!
...
Omega doesn't know!
...You don't know?
It's just... It feels like Omega promised to help someone...
But Omega's head is totally empty. Even if you hit it, it just goes clang, clang.
That's why Omega got so excited earlier. Because you smelled like Daddy.
If you were Daddy, you could tell Omega.
What Omega's been waiting for... And whom Omega's supposed to help.
...
...But it's okay. Omega can wait longer.
Omega's the best at waiting, you know!
I looked at the girl for a moment.
Given this place, she was clearly no ordinary child.
I'd never seen her before... yet somehow, I couldn't bring myself to leave her here alone.
...Then why don't you come with me?
Huh? But...
We can search for your missing memories together.
And I think I'm going to need your help.
...Heh.
Okay! Omega will go! Omega will go with you, Mister!
Oh, can Omega call you Mister? You kinda smell like Daddy, so it feels like you're my big brother!
...Big brother?
...Then uncle?
Or maybe grandp—
Let's go with big brother! I like that!
Okay, Mister!

What do you want to do? What can Omega help with?
First, we need to get out of here...
Okay, let's go! Let's go!
Omega wonders what it's like outside! Will the sun be blazing? Will it be snowing? Will there be a nice warm breeze?
Omega's got a million questions!
Ah...
About the situation outside...
Huh? Something just went ping outside.
This is... the Cube Palace?
You know the Cube Palace?
Yeah! He's Omega's friend whom Daddy made.
One time, while Omega was snoozing, a book fell right on her head!
And it was about the Cube Palace!
See? Look, Omega's got a bump now. Can you see it? It's huge, right?
When Omega pointed at her forehead, there was a burst of static-like interference.
And then, a small bump actually appeared.
...I decided to stop thinking too hard about it.
Anyway, just get me out of here.
My members might be in danger.
Okay! Got it.
Count to three with your eyes closed.

One, two... Three!
KABOOM!!
When I opened my eyes, I saw the saintesses sprawled out from an explosion.
Kyaaah! A saintess is dying here! Save me!!
I-I knew it! This must be Lord Gaph's divine punishment for shattering the sacred relic!
T-to calm his wrath, I must become a fallen saintess and offer people as sacrifice...
Admit it! You just want to do that, don't you?!
Captain! Captain, are you okay?
You suddenly collapsed and we got worried!
What's... going on right now?
Multiple unidentified hostile entities emerged from the shattered sacred relic the saintesses broke.
Entered combat immediately and now engaging the enemy.
Assumed with high probability that this is a trap set by the saintesses.
N-no! We didn't set this up!
Why would I set a trap that'd catch me in it too?!
S-Saintess Muriel... In the end, this might all just be the result of your own karma...
Or maybe... it wouldn't be wrong to say this was your scheme all along...
Shut it! You traitor!
You think I'm going to die alone here?! We're in the same boat now!
Eh?
It's total chaos...
...Kind of a mess, huh?
Take a deep breath and calm down...
Hahaha! So many people! And so noisy!
Omega's super duper excited!
You're excited about this...?!
Eek?! Where'd this kid come from all of a sudden?!
It's dangerous here with all these weird things popping out! Get out of here, kid!
Omega's not a kid! Omega is Omega!
And these are just clones!
Clones? What do you mean by that...?
I'll explain later.
More importantly, Omega, do you have any ideas?
Yup! Omega does!
Cube Palace is my friend.
So he's not bad, just broken.
And Omega can fix anything that's broken!
You have a way to repair it?
Yep! Omega just gives it a whack!
A whack?!
A long time ago, someone told Omega broken things get fixed if you hit them!
So if Omega gives the Cube Palace a whack, he'll be nice again!
Seriously?!
Yeah! Trust Omega!
