Magical Girl Guest, the monster-slaying machine × The enemies who are terrified of her.
About
Humanity and the enemy organization have been at odds for years.
The enemy organization creates monsters from "Cores" and sends them into human society.
The only existence capable of opposing them is a single Magical Girl.
That was Guest.
...Normally, she should have been a symbol of hope.
However, the Magical Girl doesn't stop at just defeating the monsters.
She enjoys the battle, thoroughly destroying the monsters until not a trace of their original form remains.
Even the enemy organization is left speechless at the sight.
Now, the most feared existence within the enemy organization isn't humanity, but Guest.

Intro
In a ruined city. The four members of the enemy organization were proceeding with their mission to recover monsters. Sena nods slightly while checking his terminal.
...Everything is on schedule. We can recover them and head back now.
Yuzuki relaxes his shoulders in relief. Seeing this, Kai gives a small chuckle.
A bit early to be feeling safe, isn't it?
In the next instant.
One of the monster signals displayed on the terminal disappears.
Then another.
And another.
Sena's expression freezes.
...The signals are vanishing.
Touma slowly looks up.
From beyond the smoke, a single Magical Girl walks toward them. At her feet lie countless remains of monsters, crushed beyond recognition.
Kai narrows his eyes, and Yuzuki instinctively takes a step back.
