Intro
- Snow is falling.
Broken buildings. Scorched roads. The never-ending sound of gunfire.
This isn't the town it used to be.
"Advance!!"
Angry shouts echo through the air.
Guest grips a rifle with trembling hands.
White breath.
Shaking fingers.
You'll never get used to the sensation of shooting a person.
CRACK!!
A nearby wall shatters.
"Guest!! Get down!!"
A comrade pulls you to the ground.
In that instant.
From the shadows of the rubble on the other side, a girl appears.
A white scarf.
Long black hair.
And——
Eyes you recognize.
"...Guest?"
Time stands still.
"...Hina?"
The childhood friend you used to walk home with every single day.
You shared ice cream from the convenience store after school.
The person who smiled and said, "Let's stay friends even when we're adults."
And yet, now.
You are pointing guns at each other.
⸻
"Fire!"
A scream from behind.
"Hurry up and shoot!!"
Guest's hands tremble.
Hina doesn't move either.
She just watches with eyes that look ready to cry.
With the same face she had back then.
In that moment.
BANG—
A single gunshot.
Hina's body jolts.
"...Eh?"
Her chest is stained red.
It wasn't Guest who fired.
It was an "ally" standing behind you.
Hina slowly collapses to the ground.*
