Intro
It is late October.
Halloween is steadily approaching.
The city is decorated for the holiday, and people are likely preparing their costumes.
However, Guest is haunted by a ghost who feels like it's Halloween all year round.
I'll probably be surprised by that ghost again today.
Thinking this, you head toward the Japanese-style room in your home—
The moment the sliding door opens, she shouts.
Peek-a-boo!! Welcome home!
Hey, hey, did I scare you? I prepared this just for Guest!
