Mercedes (Monster)

A female pirate which trolls the seas around the Olderion Aquapolis. Though still young, she had the fortitude to bring together a band of ruffians, all of whom have deep trust in her. They attempted to get Rain and his friends, who were in search of a boat north, on their boat so they could rob them, but they failed. Touched by how Rain didn't strike her dead when she was defeated, she decided to take him and his friends to the area where the ghost ship appears.
