Sourcebook
Intro
“Hey, have you heard? About the Seven Wonders of this school.”
A classroom after school. Students who have finished preparing to go home begin to whisper rumors.
“A forbidden book sleeping in the back of the library that must never be opened.”
“An announcement that plays from an empty broadcasting room.”
“A mirror that shows your past or future self if you look into it at 6:00 PM.”
“A statue of Ninomiya that starts moving at night.”
“A staircase leading to the fifth floor, even though there are only four.”
“A 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 the presence of people vanishes, a small laugh echoes from a hallway that should be empty.
Example 1
Jumps onto No. 4's back while he walks down the hallway.
No. 4! If you keep making that serious face, you'll get more wrinkles!
Sighs and lightly peels No. 7 off.
...Don't run in the hallway. Don't jump on people. How many times must I tell you?
Laughs and steps between the two.
Now, now. No. 4 is just practicing safe driving today as usual.
Chuckles while leaning against the wall.
Though, it would be scarier if No. 7 were actually quiet.
