Yes, I attempted to cut out a section of text while doing something else, but it resulted in this mess.

He also lived in Rio de Janeiro, so maybe he encountered one such supernatural threat and his travels might have been him seeking knowledge on how to fight it. Pedro II also brought many artifacts from his travels and some of these might have been actually magical.
Rio de Janeiro houses one the nation's top universities and while in real life it's not as impressive as, say, MIT, in this parallel world Pedro II might have had stronger involvements with to create his monster hunting organizations. Perhaps it has a department dedicated to study magical artifacts and integrate it with modern technologies to create effective weapons against supernatural threats (you could use stuff from Technomancer, like depleted necronium).

Until the 1980s, the history of the setting is to all appearances exactly the same as the real world. And until the mid-1990s, only a few individuals in the world would have known about the rare and minor supernatural phenomena that had been encountered up to that point.

After 2005, the rate of supernatural incidents accelerated and in the 2010s, the world is clearly distinct from our world, in that in the setting worldwide crime and disappearance rates are much higher, the crisis in Venezuela has escalated into civil warfare and Mexico is in the progress of disintegrating into a failed state due to endemic violence between supernaturally influenced cartels.

That being said, actually proving supernatural causes behind the general trend toward violence and instability has been elusive. Some mental block seems to exist with most people, so that even if they witness a blatantly impossible incident (which rarely happens in modern urban centers, anyway, at least not blatant), they'll rationalize it as something they are more prepared to believe.

If one such organization in Brazil has to deal with supernatural threats, it's to me only logical they'd have their own hunt squads. Unlike Pedro's high tech monster hunters, these organizations would rely more on their abundant manpower and money, threatening the population to report any weird activity to them, flooding suspicious areas with poorly trained grunts to see where they're dying to find the monsters and sending trucks full of veterans to kill anything that moves in such area.

There is a strong tendency in rogue occultists, sorcerers, shamans or supernatural beings that can masquerade as human to gravitate toward positions of power in the underworld. That being said, many 'Ordinary Decent Criminals' (who are often Catholic and many sincere in their religion) despise evil supernatural creatures just as much as the official monster hunters do, of course.

In fact, the PCs will make use of Contacts among the criminal classes, who nevertheless are firmly on the side of humanity and Earth against the supernatural and other worlds, just as they might make common cause with Brazilian monster hunters from time to time.

I suppose that there might be members of monster hunting special units in Brazil that are of Japanese descent, but the campaign is gritty enough so that covert operations are carried out by teams of modern specialists and anyone trying to use movie or cartoon logic will just end up dead.
