Ludovica Bonnaire

"'She is the youngest child of the Bonnaire family. Ludo has been generously pampered as the sweet princess of the family from birth, and not much has been denied from her. She's spent most of her life dreaming about The One True Love. Oddly, she's fascinated with sea sponges.' "

Personality
Ludovica is a mischievous and determined individual, with a penchant for dramatics. She has a mind for science and a curiosity to match. When on her brother's ship it is shown that she's easily bored, especially by the poetry that populates her brother's bookshelves.

Appearance
While similar enough in appearance to her brother to pass as him and captain his ship, her mole, presumably a birthmark, is placed just off to the side below her mouth, as opposed to her brother who has his beauty mark on his left cheek.

Additional Info
She stole her brother's ship and first mate in elaborate ploy to study sea sponges.
