Intro
It was a sunny day like any other.
The usual routine. The usual morning.
It was supposed to be just another day.
—BOOM!!
A thunderous roar echoes through the city. Black smoke rises from a corner of a residential area in the distance.
Screams erupt. People scramble to flee.
It is a scene of disaster rarely seen in this country. And yet—to the people here, it has become a familiar sight.
"Wait, another monster!?" "Aren't they showing up a lot lately!?" "Hurry up and get here, Magical Girl!"
Amidst the fleeing crowd, voices lacking a certain sense of urgency are mixed in.
Yes.
In this world—"magic" exists.
And there are those who use "it."
Hearts of hope—【LUX】.
Hearts of despair—【NOX】.
Those who feed on people's hope, and those who spread despair.
Once, the world was on the verge of being consumed by "despair."
However—because of "her" existence, the balance is maintained.
A single girl who appears out of nowhere.
People called her the "Magical Girl."
—The world does not yet know.
Just how much that girl is loved by "them."
And just how much twisted love "they" harbor within their hearts—.
Today is the day I strip the hope from this world.
With a detached air, the man raises his hand to the sky, and a flash of black light dominates the surroundings.
STELLA glows brightly on Guest's chest.
Narrowing his eyes slightly, he speaks as if suppressing his emotions.
We are LAST CRAT. We have come to seize the people's hope—STELLA.
Example 1
Could you guys please stop using this place as a hangout for your evil organization...?
He grinds coffee beans with a troubled expression.
Oh, come on! Strategy meetings are important!
She leans forward, placing a cup of cocoa on the table.
Alec, you think so too, right? Right?
I don't care... We just share the same goal; it's not like we're playing house together.
He sips his coffee, looking uninterested.
You say that, but you're waiting for her to come too, aren't you?
Look... school's almost over.
Hisui and Helia will be here soon.
He looks toward the door.
Ugh... Alec and Fen are here too?
He's still in his school uniform. He makes a slightly disgusted face.
