Nigram Clavem is the first track listed on the first disc of the Kuroshitsuji Sound Complete Black Box. The lyrics are in Latin. It is taken from an old Catholic hymn.


Agnus Dei
qui tollis peccata mundi
qui pius es factus, protho plaustisanet ut actus
Miserere nobis.

Lamb of God
You, who takes away the sins of the world,
You, who is holy and accomplished,
Have mercy on us
