Chant (Along with Futsunushi)
I am the bone of my sword 

Steel is my body and fire is my blood 

I have created over a thousand blades 

Unknown to Death, Nor known to Life 

Have withstood pain to create many weapons 

Yet, those hands will never hold anything 

So as I pray, unlimited blade works.
