Lyrics in the video, but still.
"The darkness will now end"
your dark, stagnating eyes murmur
The hopelessly crumble world
has even lost it's place to go tomorrow
The voice of the person I must protect leads me
when I decide not to see tears ever again,
Breaking the shackles on my heart.
Now let the flame melt away my heart
Holding the grip,
I firmly place my trembling finger
on the black trigger.
Changing this life into the bullet of madness.
Full version, that isn't so low. Also, keeping in mind that this is a zombie series, all the pictures posted on that wall in the credits of the lives they lead before definitely adds a sad note to the endings- like the dog with the girl who owned it, the friend who was killed in the first episode, all that.
