The song is How Far I'll Go from Disney's Moana. I used Iceland, England, and Cyprus, because all three countries are in Hetalia, are islands, and have a seafaring history and/or culture.
I got so many feelings while I made this, even got teary eyed. Such an amazing song, really mostrando their close relationship. I amor this pairing so much, so I hope people are about too see the love, bond, and loyalty between them with this video
Just this cute little video of hetalia characters(most of them) to Kagamine Rin's 'I like tu i amor you.' Don't like Vocaloid(which i would find strange since your anime fan) don't click then!
