I thought he was a woman at first...Then I saw this clip of Illuminati live, and I realized he was too flat chested to be a woman.
I remember I had thought it was so cool that 'she' was the only female, and was band leader and stuff. then I fund out Mana was a man and was like "Whoa, wait, what?" XD Then I was like "But Gackt molests him and things..." And I've been in awe of Mana(and a fan of fanervice) ever since.
I've got a gif of the exact second I relized Mana was a man, actually. XD I have gifs f everything. ^^
