It’s kind of weird that this is actually the most serious and calm I’ve seen Yanagi be so far. I wonder if he does know anything about the dragon after all? He’s extremely interested in historical artifacts, so maybe he’s heard something about it before in connection to that.
Heh, well this old man has apparently been in and out of the system for a long time then if he’s experienced enough to know how to hide cards and smuggle them in. I wonder if the prisoners also use cards as currency with the guards here?
