Who am I? ５

Who am I?

前回はやややさしかったようですから

今回は少し難しいかもしれません。

ヒントが少なすぎるかな？

My last hit made a small hole

through the thick rock.

Bright sunlight filled into the darkness

and my dirty,

white hair glittered in the light.

It was a long time ago.

30 years had passed by

since I began my work on this task.

My young, black hair had turned white

which was the symbol of my long, lasting hardship.

I sat down and gave a long sigh

with no one to share my joy

except the man who had come to kill me.
