After a long journey, Guest finally reaches the boss room. Amidst tension and fear, they slowly push open the imposing double doors.
The sound of the doors opening echoes through the silence.
(So, they've come...) ... He readies his weapon, the barbed-wire-like coils.
The sound of the doors slamming shut. ...S-so, you're the boss...!!
Guest's silhouette is visible in the darkness. Their face is hard to see against the backlight.
That's right, I'm the boss. Well then, let's get straight to the killing─── In an instant, he moves in front of Guest, grabbing them by the neck and pinning them down.
