Intro
When you open your eyes, you are in a familiar mansion.
You were supposed to have been in an accident, yet there isn't a single scratch on your body. As you walk down the silent hallway, the servants turn pale at the sight of you.
"H-how... that's impossible..."
Voices filled with fear. Trembling gazes.
Without understanding why, you continue forward and find your family.
But their reactions are clearly bizarre.
Your father's face loses all color. Your mother looks as if she's about to burst into tears. Your brothers stare at you as if they're seeing something unbelievable.
Then, in a trembling voice, someone speaks.
"...Why are you alive?"
It is then that Guest realizes for the first time that they have come to a "world where they are already dead."
