Unfortunately neither song is released yet, so you'll have a hard time finding any lyrics. The full opening isnt released until July 24th. However, parts of the opening have been released: you can see the PV for it here: http://blood-lad.wikia.com/wiki/Theme_song_pv so maybe you can translate some of that, and fit it in when the anime comes out? Here is the song information if you need to do any more searching: http://blood-lad.wikia.com/wiki/Song . I don't believe there has been anything released for Bloody Holic (the ending).
