Oh, I already got it for you from a wordpress blog named Word of Songs (http://atashi.wordpress.com/2006/09/18/xxxholic-movie-theme-sanagi-theme-from-xxxholic-the-movie/):

Sanagi : Suga Shikao

As if you can directly and clingingly touch my body’s thin mucous membrane
Those insensitive fingers of yours didn’t shudder and hate me
But whenever it came to you, you’d leave me behind and give nothing but lies
From the start, you made a habit out of thinking that I’m a fool…

I didn’t think that a day like this would come
But I still feel your presence over there

After you left, my body has already since then turned chrysalis-colored and dried out
I’ll be reborn in the cold room of winter, just like a beautiful butterfly
Those wings are still wet, so that I won’t be made useless by someone else
I’ll open them little by little, dreaming about flying in the sky…

If a day like that suddenly came about
I wonder, then to where should I fly with those wings?

Like how livestock don’t have names, I’ll forget your name
Rather than remembering you and crying, I’ll erase you entirely

Will a day like that come about someday?
Are the days with you already forgiven?
Will a day like that come about someday?
The splendid days will be someday…
