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 showing 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 - axis powers characters(most of them) to Kagamine Rin's 'I like you i amor you.' Don't like Vocaloid(which i would find strange since your animê fan) don't click then!
