Music upon the Waves

Madoka Magica Pirate au!! My friend came up with this idea and I live for it!! This is mostly about Kyoko and Sayaka, (and it ships them of course) but the other characters will show up once in a while. Also, this is my first fanfic so I know it will be bad please forgive me. I also don't know how often it will upload. Swearing warning!

Kyoko became a pirate for one thing and one thing only: to help her dad gain his job back at his church. But when it backfires and she gets disowned, she decides to be a pirate that only helps out herself. But what happens when she meets the mermaid Sayaka, who is in love with a human boy?
Disclaimer I do not own any of the characters in Puella Magi Madoka Magica, they belong to the original creators.
