Pretty sure this should be in the OSTs and AMVs section of the forum...
Well if you don't care about the translated lyrics, animelyrics.com does
have the lyrics for the OP. (I will try to track down the ED lyrics)
Seishoujo Ryouiki by ALI PROJECT
Here's partial translation (for TV version):
Saintly Girl Territory
Please don't say those cursed words yet
Love is light like feathers
If you're ready to rob with the whispered tenor that is kinder than papa
More fragrantly than the dream that I have and is buried in millions of beds of roses
I am alive
What to do? In this world that ugly things overran
Can I go and fly unblemished?
Alone in the cocoon, even if I continued to learn
The crystal starry sky is too far away
Please don't let your trembling fingertips touch me yet; a flower-stealer's sweet hesitation
You may touch me, if you're confident that you will reach to the depths of my profound chest
Isn't there a reason to believe in my prince on a white horse?
*EDIT*
Here's partial lyrics for the ED, "Hikari no Rasenritsu (Spiralling Melody of Light)" by Kukui
