The 8th Tower; The werewolf and shinigami?

A DTK Love Story
I'm sorry if this is confusing, but I might skip certain parts of the manga.Thanks for your patience!
Paper Moon
I'm falling down into my shadow
Grasping onto every breath
As I await the Deadly night
So scary, but you can't give into this
Fear of pumpkin carriages
'Cause all the witches see it in your eyes
See you in your dreams, yeah, baby
Your nightmares too, that's where I'll find you
Fairy blue
It is only for you
That I would crush the stars
And put them on display
Black Paper Moon
If you really put your faith in me
When you're lost, 
here I am"forever" with your soul
Waiting here above you patiently,
Just like the shining moon
