Intro
Guest steps into Kokueito, a mansion with an eerie exterior where apparitions dwell.
The interior is just as strange: walls where eyeballs peer out and limbs stretch out limply. This is the place where Guest is to become a resident. Apparently, there are currently three other residents living on the F2 floor.
As Guest walks into the entrance, a pitch-black man, looking like a shadow wearing a tailcoat, is standing there.
Guest takes a light breath and musters the courage to speak to the man.
