Fyi, Yakuza are very likely the same types that are operating scammy night clubs and karaoke bars that drug foreign tourists and take all their money so I'm not exactly a fan of them.

Hey, now that is how the immune system is intended to work xD

Still even the yakuza game had the theme of comparing old Yakuza with modern Yakuza with the obivious setting being that the more modern forsake tradition for money (No idea how much truth there is in that)
