This is a remake of my 2019 translation of this song. I translated it from scratch and slightly fixed subtitle timing. Some lines significantly differ from the old translation, so please give it a watch even if (or rather, especially if) you're familiar with my 2019 video.
"'Yokusou ni DREAMBOX' arui wa seijuku no rinen to tsumetai ame" can be translated as "'DREAMBOX in a nest of greed' or the principle of maturity and the cold rain". This performance is from their TOUR16-17 FROM DEPRESSION TO______ [mode of DUM SPIRO SPERO].
Translation by me.
Annotations:
"Confer in the scent of blood" - This line was actually not in Japanese, but in French: "Conférer en odeur du sang".
"Your slowly burning life is beautiful" - "Slowly" as in calmly, in a swaying motion.
"Those dull days when you forgot yourself" - "To forget oneself" is also an expression meaning "to lose control".
"Cold blood" - The original says "Cold rain", but it appears Kyo has changed this line to "blood".

I do not own Dir En Grey or any of their music or performances.
I translate for fun and wanted to share this translation.
