The Empress is a creator, be it is the creation of life, of romance, of art or business. While the Magician is the primal spark, the idea made real, and the High Priestess is the one who gives the idea a form, the Empress is the womb where it gestates and grows till it is ready to be born. She is the other feminin card that offsets the male power of The Magician. She is beauty, nature, fruitfulness and motherhood.
This is my idea of what Shin's only sister might look like. With her is Shin's faithful friend, the orca that helps him over and over in the TV show. She is holding an earthenware jar, showing her role as the one running the family pottery business. This character is from the series Yorodien Samurai Troopers and used in the fanfic 'AmoureuX'.
