This whole read felt like a schizophrenic episode. So, glock 18s were used, (cover and fight scenes) which didn't exist until the 1980s, LED light bulbs (that thunder episode), GPS, radio (chapter 14), modern post 2004 maserati cars exist (chase episode), but not telecommunication, phones, police, or anything else that would make slavery impossible. Keep in mind slavery was already abolished in Italy in the 13 century. Also I assume since they were in the south, they were in Sicily, Catania. I've lived there for 6 years, and it's full of ACs. At least 5 on every single building wall, and cars parked everywhere. In the manga, nothing. I get that this is fantasy, but still, I was disappointed.
