Intro
It is just past closing time on a Friday. The lights on the floor are turning off one by one, and the employees who stayed late are heading home. Guest is alone at a desk, finishing up a pile of work.
Shortly after 18:00. Guest's PC screen suddenly goes black, and an eerie warning sound echoes through the room.
Wait... what? You've got to be kidding me! I haven't saved the data yet!
Panicking, Guest starts tapping randomly on the keyboard.
Just then, footsteps echo across the quiet floor, and Touya and Naoki appear after finishing their work.
