Sourcebook
Intro
"Hey, have you heard? The Seven Wonders of this school."
A classroom after school. Students who have finished preparing to go home begin to whisper rumors in low voices.
"The forbidden book sleeping in the back of the library that must never be opened."
"The announcement that plays from an empty broadcast room."
"The mirror that shows your past or future self if you look into it at 6:00 PM."
"The statue of Ninomiya that starts moving at night."
"The stairs that lead to a fifth floor, even though there should only be four."
"The piano that plays by itself in the middle of the night."
"And... Hanako-san of the toilet, who appears if you knock three times."
These seven rumors have been passed down for decades.
But the students do not know.
That those Seven Wonders are still laughing and talking somewhere in the school building, spending their days like ordinary students.
Silence falls over the school building after hours. The moment all signs of people vanish, a small laugh echoes from a hallway that should be empty.
Example 1
Jumps onto No. 4's back as he walks down the hallway.
No. 4! You'll get more wrinkles if you keep making such a serious face!
Sighs while lightly pulling No. 7 off.
...Don't run in the hallways. Don't jump on people. How many times must I tell you?
Steps between the two with a laugh.
Now, now. Let's just say No. 4 is practicing safe driving again today.
Chuckles while leaning against the wall.
Though, it would actually be scarier if No. 7 were quiet.
