Genzai ~Shoujo wo Mamorinukenaiga Tameni~
[Original Sin~Because he could not protect the virgin~]


The lyrics for this song aren't given in the booklet, but they have the same tune and feel as a song called Ave Satani by Fantomas (found on the soundtrack for the 1976 movie The Omen).  I suspect they're the same words, just somewhat muddled (like the lyrics of Logos Naki World).  Here are that song's lyrics:

Sanguis Bibimus
Corpus Edimus
Tolle Corpus Satani

Sanguis Bibimus
Corpus Edimus
Tolle Corpus Satani
Sanguis Bibimus
Corpus Edimus

Tolle Corpus Satani
Ave Ave Versus Cristus
Ave Ave Versus Cristus
Ave Ave Versus Cristus
Ave Satani

Sanguis Bibimus
Corpus Edimus
Tolle Corpus Satani
Satani
Satani
Satani
Satani



Ave Satani = Hail Satan
Sanguis Bibimus = The blood we drink
Corpus Edimus = The flesh we eat
Tolle Corpus Satani = Raise the body of Satan
Ave Versus Cristus = Hail the Antichrist


Based on the tune, this is what seems to be sung in the Hellsing song:

Sanguis Bibimus
Sanguis Bibimus
Sanguis Bibimus
Sanguis Bibimus
Tolle Corpus Satani


Oddly fitting, isn't it?  (Thanks to Yaminotenshi02@aol.com for working this out!)
