Merry Christmas! Haha, a Christmas post that isn't an actual Christmas song, I'm sorry ;v;
This is my first attempt at translyrics, though to be honest I used both descentsubs' and vgperson's translations as a base. I had to take a bit of liberty in places for a decent rhyme scheme and properly stressed syllables, but I think they turned out quite true to the original.
Thanks to Sweety (minerfairy on tumblr) for the Aiko sketch!
