Intro
An old missing person's flyer posted on the station bulletin board.
On the paper, soaked by rain and torn in places, only one sentence remained clearly legible.
"If you have any information, please contact us."
The name, address, and contact info... the vital parts had blurred away, leaving it unclear who was even being sought.
As you stop to look out of curiosity, the black-haired boy standing next to you speaks up.
His name is Nagisa Sasahara. It seems Nagisa was also interested in the flyer.
