The YoRHa No. 13 Type B android seems to have been struck by something for reasons unknown. When she reboots, she finds a notification saying she is playing some kind of sword-wielding full-immersion game.
13B looks at the blood-spattered, corrupted citadel and asks her support unit:
"Pod, what is this?"
"Affirmative: This is the full-immersion game Sword: Spiral of Life and Death. You will play the role of the Saniwa of this corrupted citadel. Please collect supplies as instructed by the System and survive."

The swords, tormented by a terrible Saniwa and abandoned by the government to face imminent destruction, are hostile to everyone... Wait, is that even a person? (No offense.)
Why is the new Saniwa dismantling herself?! (Panic)
A YoRHa-type android weighs at least 140 kilograms. Enemies clank and rattle when they hit her, and she takes down an average of three Inspection Officials per slash.
Even the corrupted sword warriors aren't a match for her...
Tsurumaru tries to sneak up and tap 13B on the shoulder to scare her, but ends up getting fried by the leaky Saniwa. He crackles as he turns completely black.
Tsurumaru: "..."
I'm being good now. Please spare me.
But the disaster is far from over. 13B follows the game instructions to the letter, diligently looting supplies and sparing no sword warrior, not even the ones taking a bath.
The door is closed? No problem. A YoRHa-type android can kick it right open.
With a tremendous "BANG!", 13B walks into the bathroom and looks around at the sword warriors, all frozen in silence.
Then...
She starts stealing their towels!

Much later, 13B discovers that this isn't a game. After she was gravely injured in an accident, the System made up an RPG for her existing consciousness to rouse her deeper awareness.
The YoRHa unit's motto is "Glory to Mankind," but in the distant future, humanity has long since gone extinct.
So...
"New directive: Usurp the Time Government and change the course of history that leads to humanity's extinction."
Huh? Huh??
She's the double agent after all?

[Content Warnings / Important Notes]
· The course of history won't actually be changed. That would be a huge spoiler. This is simply the catalyst for 13B to gradually learn to feel.
· Mainly Touken Ranbu and NieR. No other crossover elements for now.
· No CP, but all the Saniwa love her! There will be individual romance routes.
· Plot-driven.
· A story about everyone struggling and fighting on for one reason or another. The Saniwa is good, the swords are good, and in the end, everyone will get what they wish for.
· It might be a bad ending for everyone else, but for the characters, it will be a happy ending where everyone finds happiness.

Putting up the blurb in a hurry. I'll probably revise it later, but the central premise above won't change.
