I hesitate to post this since the song is a musical spoiler, being the true final boss theme of Ys Origin that you need to have played through the game at least twice to get to (or three times to get the full story). So play the game first if you haven't, it is excellent (a challenge, though, the excellent soundtrack is required to keep you going :) ).

I had no idea even after hearing it a bunch of times but the lyrics are actually in English, I couldn't even hear them after learning that until I saw the lyrics to times comment :/ (and even then it is hard, which I should say is not a criticism of the song which is at least as good not hearing the lyrics).
