Original Lyrics by Demon Kakka, or His Excellency Demon......... mmmkay.
Anyway, this song is awesome but really weird, particularly that part before the final chorus. While I usually retain lyrics already in English, I decided to change "Extreme like as Dragon Balls" because... well, it's obvious. So I refer to the Dragon Balls as nightmares in the sense that they are being used to sinister purpose by Freeza.
...Look, it makes sense to me, okay? Also, just in case anyone finds that set of lyrics confusing, the parenthesized lyrics are the chants in the background (for which there was no translation so I just made 'em up) and the unparenthesized lyrics are the main vocals.
