My reading on Vali's DxD L chant (take it with a sack of salt. I also use Ise's DxD G chant as a reference):

O Pure White Dragon dwelling inside me, rise from your supremacy.

For I am the descendant of the silvery white Morning Star who reach the throne of the dawn.

The Jet-black God of Infinity...

The Father of All Devils...

We will accept and overcome all admonition to become the ultimate being.

All of you, kneel down before our brilliant and bright existence!
