Keita's comment? "It's a sad story of a man who has nothing to believe in. Everyone, let's be careful to not hurt others with mischievious love!".
So, not really a fun fact, but "Masquerade" is misspelled on their website as "Maspuerade". It's written correctly in the lyrics, though.
First night 背中に感じる合図
濡れた舌に溺れちゃ
出来すぎた言葉ばかり 重ねただけの罪とランデブー
ただ絡み合う吐息だけ 色鮮やかに揺れる
Last night 飾りたてたオブジェ
いつか壊れてしまう
きりのない欲望ばかり 重ねただけの罰とランデブー
ただ奪い合う喜びに 落ちてゆくがいい
Welcome to my masquerade
誘われるままに 踊り続けよう
Break your mind just sweet Joke
Don't you know? 愛はない
I'm a ghost of your love.
何もかもただ求め合う悲しみに 落ちてゆけばいい more
Welcome to my masquerade
氷の様な瞳で 滑り込む秘密
Break your mind just sweet dance
やがてdeep inside I'm a ghost of my life.
Welcome to my masquerade
抱きしめた肌にはじかれる前に
Break yourself just sweet Joke
Don't you know? 愛はない
I'm a ghost of myself. I don't care・・・
