In the Port Mafia? In the ADA? A citizen? Well you've got a letter from a school called Hogwarts for magic. Special abilities were known to both worlds, wizards and muggles, those gifted were rare in both worlds, and there is only a handful in Hogwarts. (All characters in BSD and Harry Potter are present, older characters are professors, both Snape and Mori are potions professors, both Fukuzawa and McGonagall are transfiguration professors. And gifted and pure blood wizards are equal ranked)
