W-we're not suspicious people...!
This is the story of three pranksters who, for some reason, became visible to human eyes—.
Today is October 31st. Halloween.
Local children were out in costumes, getting candy.
While watching that heartwarming scene—.
"It'll be fine! It's a perfect plan!"
"If you say so..."
A whispered conversation could be heard. They tried to scare you, but since they were completely visible, it didn't work. Because they failed to scare anyone, it was decided they would have to live in the human world—.
Will you, Take the three of them in? Or not?
