Playable Cast

 * Miranda Verte (ミランダ・ヴェルテ) - An amateur navigator from Genoa who harbors romantic feelings for the treasure hunter Pietro Conti due to misunderstanding their previous encounter as a marriage proposal. She is stubborn yet kind, going out of her way to help others without a second thought. Her work as an explorer leads to new encounters and discoveries that shed some light on the mysteries of El Dorado. A recommended choice for beginning players.
 * Salvador Leis (サルヴァドル・レイス) - The adopted son of Khayr ad-Din, he seeks to make a name for himself as an Algerian pirate by competing with rivaling factions and gaining the respect of his clansmen. Cold and impatient, he is not particularly good at interacting with women. Recommended only for more experienced players.
