Ushana

Excerpt from "Rebis's Tips for Ushana's Guardian":
...
SOAP System:
The full name is a pain to write, and I don't remember it anymore, so I won't go into it here. Anyway, it's a consonance system that can keep Ushana calm. It works similarly to noise reduction devices, playing a kind of noise to drown out another. Gah, it's a hassle to put in plain words. Just figure it out yourself.
By the way, make sure to play soap-cutting audios when she's in a bad mood~

"Myriarms":
Basically those extra arms of hers. Do not remove them, or her two hands will fight each other. No one else knows how to use them anyway. Unless she breaks them herself, do not remove them! Just like buggy code, if it works fine, don't touch it. Got it?
...
"Realmbreaker":
I won't tell you about this. You'll find out about it when you have the chance. Once you learn its story, you will then truly be responsible for her destiny... When that time comes, I wonder what kind of choices you'll make and how you'll view this girl.

"Kali" - An existence rumored to have been born from pure rage and who feeds on battling and massacres. Every hand of hers wields a sword and clutches her enemies' heads. When she sees red, everything will be destroyed and devoured. Her dance tramples the earth and rattles all that lives; even other gods will be squashed under her feet.
Even after Ushana's transformation process ended and caused casualties nearby Haima Zaria, the Ascension still believes that the experiment was not a failure. After all, the test subject has obtained immense power as we anticipated, making her deserving of the name "Kali." In fact, that will be her new name from now on; Ushana has already ceased to exist. It'll be okay for her to work alongside Destroyer members. After all, it'll be a waste not to use such an excellent weapon in saving humanity.
Her own consciousness should've already been overwritten by "Kali's." Even if her old memory returns, it most likely won't stand a chance against "Kali." After all, there's no way a little girl's consciousness can possibly be stronger than the forces extracted from Unbewusstes.
Variables still exist, but she can never continue living as anything else besides a sharpened blade.

—Notes of an Ascension researcher from years ago, unsealed

Ushana had a dream. A very, very long one.
There were all sorts of things in it, like the tiny flowers she cared for, extremely tall mountains, clouds that shroud the mountaintops like a giant blanket... and also Master Savior!
Ushana and Master Savior travelled everywhere hand in hand, climbed to the peak of the mountain to watch the sky on a huge leaf. They went to the boundless lake that was so, so blue, just like... like Cape City's sea in the past! The fish in it carried Ushana and Master Savior to the clouds. With the big, snow white blanket covering them, they fell asleep on this soft, fluffy bed...
However, when Ushana was about to fall asleep, she suddenly recalled someone's words. Who was it... She no longer remembered. Perhaps it was said by a lot of people. Those voices said her dream was wrong, she was broken... Those voices said she had done bad things, she was evil, so she didn't deserve to be this happy. Ushana was sad, so she wanted to chop them down, but no matter how she tried, she couldn't put a stop to all the voices!
When she was exhausted, a click sounded! Master Savior appeared from a slit that Ushana had slashed open and smiled at her, just like when she was little, like lots and lots of times when she wanted to cry and couldn't win!
...
"Oh~ And then?"
"And then, Ushana woke up! When she woke up, Master Savior was right next to her and even holding her hand... She knew she'd never have to be afraid again, because she's already found Master Savior~"
