The Magic Trio come together to practice some magic spells in England's basement. But when a spell goes wrong Hungary, Denmark, and America get teleported to England's basement with a clearly visible change. They were children! But not just any kind of children, the spell somehow enhanced the magic in them. Now they had to be enrolled into Hogwarts until the Magic Trio could figure out how to change them back. But to keep a close eye on them to make sure they don't get into trouble, the magic trio becomes the new security guards of the school. The Golden trio become suspicious of these new comers along with Draco and want to find out what they're hiding.

Set in modern Hogwarts the headmaster, Neville Longbottom decides that he wants his students to adapt to different wizarding cultures of the world. He contacts the headmasters of different wizarding schools and they set out an exchange programme. Harry Potter/Hetalia crossover Based off of headcanons, hints of SuFin, GerIta and other ships I cannot be bothered to list. Still understandable if you don't know what Hetalia is, but then why are you here if you don't know what Hetalia is?
