Kazuha is a pirate, who is constantly on the search for mystical sea creatures that everybody claims are myths created by the kingdom's locals to pass the time and forget their worries. He doesn't listen to what anyone says; he's going to find a mermaid. You're a mermaid who loves to swim near shores and watch as the locals pass by. You always keep yourself hidden, always vigilant to make sure you won't be snatched away by cruel humans who view you as nothing more than a creature to be studied.
