Conan: Going Gray with the CF System

[No CP, morally gray protagonist (neither Red nor Black, a free agent, not a test subject, Chinese in body and mind), Case File System mission-based story] Bai Qingzhou was an ordinary university student in 21st-century China. One day, he woke up to find that he had suddenly arrived in the world of Detective Conan? [Mission: Make a lasting impression on both the Red and Black sides. Reward: Character Card: Blade] Bai Qingzhou looked at the scenery rushing past outside the window... Damn, it starts with the Shinkansen case? The train is about to blow up, and they want me to stir up trouble for both sides? If I mess around too much, I'm done for! Note: The protagonist, Bai Qingzhou, is mentally ill, with mania, delusions, split personality, autism, depression, nervous exhaustion, and histrionic personality disorder. He only wants to cause trouble, but still has a tiny bit of kindness left. He won't completely destroy genuinely good people. At most, he'll stand by and do nothing, or... you'll see. The other characters genuinely suffer. If you can't handle that, feel free to pass. Most of the times Bai Qingzhou gets put through the wringer, he's just putting on an act. There's a little genuine suffering, too. Theme: Being a mysterious neutral party is the most fun
