Song Title: Princess Mononoke Theme Song (Mononoke Hime)
In the moonlight I felt your heart
Quiver like a bow string's pulse
In the moon's pale light
You looked at me

Nobody knows your heart
When the sun has gone I see you
Beautiful and haunting but cold
Like the blade of a knife
So sharp so sweet
Nobody knows your heart

All of your sorrow, grief and pain
Locked away in the forest of the night
Your secret heart belongs to the world
Of the things that sigh in the dark
Of the things that cry in the dark.
