After Riviere saved her from dying on the street, MacMillia chose to start working as her new assistant! The enigmatic Riviere runs an antique shop, where she specializes in dispelling troublesome (and sometimes dangerous) curses. Magic, witches, prayers (and the curses they turn into) mean there's never a dull day for these two!
