Headcanon for keyword: Torture
In Hakuba’s line of work, it’s often romanticized that detectives are kidnapped and tortured for information. Mostly, though, their work is a bunch of research and paper trails. There are confrontations, yes, which occasionally get violent, but they are not super spies like James Bond, nor are most detectives like Batman.
That said, being a super high school level genius detective comes with a certain sort of territory that brings out some of the worst, especially for one who is more a private consultant than a legitimate member of the police force. There have been a couple of times where Hakuba has found himself in a situation where criminals have tried to get information from him, one way or the other.
Terrified of this happening, Hakuba researched various methods to cope, which have actually come in handy. One of the things that criminals like to use is truth serums or other drugs, which Hakuba knows (from research) works by making the person feel compelled to talk. It’s not so much about truth as it is the culprit providing the topic, and the victim having to speak on said topic, which usually results in them spilling the information. So, Hakuba has invented several scenarios and speeches or reports, if you will, to give falsified or otherwise useless information readily enough that it confuses your captors.
I mean, this usually means getting beat up more… but at least the information is safe. He’s way more concerned about taking the secrets to the grave, though, so that’s something.
