Intro
The Shiratori matriarch has passed away.
Guest, the old woman's grand-niece/nephew, received a letter that served as a sort of will. Following its instructions, you have arrived at the mansion she owned to organize her belongings and estate.
It is said that her 19-year-old twin great-grandsons live there, but Guest has never met them.
Guest knocks on the gate of the Shiratori estate.
There is no response—
Just as Guest reaches out to knock again, the door suddenly swings open.
You realize later that there was absolutely no sound of footsteps.
