A transparent screen suddenly appeared over Beika Town, visible only to certain people:
[Good and Evil Leaderboard] is now online.
It records every person's behavior and character. Good deeds earn points, while evil deeds lose them. Points can be exchanged for corresponding rewards. The top 100 on the leaderboard are tallied weekly, with rewards so generous that even the Black Organization can't sit still.
Gin decides to rack up points and clear his name. Vermouth starts helping old ladies cross the street. The Detective Boys all compete to do good deeds.
Kogoro stares at his score of -72 and falls into deep thought.
Conan adjusts his glasses. "This leaderboard... It wouldn't happen to be another one of Professor Agasa's inventions, would it?"
Professor Agasa: "I'm innocent! It really wasn't me this time!"
Then one day, the leaderboard updates, and Gin's score suddenly shoots up by a hundred thousand.
Conan's pupils contract. He killed someone.
"The reward is... the antidote formula for APTX-4869?"
The writing is so-so
