This is rather odd...but doe anybody know which manga this poem is from?

"O Goddess Fortuna,
Thou changest like the moon,
Waning into a crescent,
Filling into a wane.
With no such heart of this world,
Grasping joy and pain to your convenience,
You play with people's heart.
Hiding amongst the shadows,
Thou captures me.
As I helplessly stam,
I can only open myself up to be subjected to your treatment."

I typed up a poem that one character was reciting and I found it recently - but I no longer remember which manga it was from. Help?

Did some digging around and found that it's called O Fortuna. More digging around said that the only manga it's mentioned in is Battle Angel Alita. Hope that helps.

Sorry I don't think that's it, but thank you finding the title of the poem!
