Yo ho, ho, a pirate's life for me...

Leon has lived his whole life on the sea: first as a fisherman's son, then as a stolen token, and now, as a pirate in his own right. A man with the heart and parts of a machine, there is little in the world that sways him, especially not the batting eye of a stranger at port. And yet, he is drawn to this man, this beauty who follows him aboard and sings with the voice of a siren.

While there are more important matters to attend to like dodging tempests and wrangling the crew, Leon is unable to resist his song. Can the steel of a wounded heart melt, or will Leon's heartstrings be plucked to nothing?
