Well, well… Better late than never, I suppose. Hopefully this will satisfy your want of music to assault your ears (in the nicest way possible, of course).
I remember taking a liking to this song, and the series, upon my introduction to Kamen Rider Decade at one of our Weekly screenings. Perhaps this is not the best Kamen Rider (or the best song) out there, but it’s still worth a listen. There are some nice visual effects, and who can say no to Gackt?
