Japan is an odd place culturally speaking. They have terrible gun laws, and generally the odd parts of it aren’t contested. Such as the good people being disarmed by law…and the Yakuza operate in the open, and are simply assumed to be armed by all.
Essentially the “Girls” in the series are actually “Guns” (how that is isn’t exactly clear to me), but one of the “girls” notes that guns can’t hurt people by themselves, and instead its people who hurt people.
That’s rather a lot coming from Japan!
