Doppel of Magical Girl
Ophelia, derived from the Greek word for "help", is also the name of a character from Shakespeare's Hamlet, who was a young woman who had a high romanticized suicide and has been linked to the ideas of regret, corrupted innocence, and unrequited love.
In the play, Ophelia's main conflict was between obeying her father or her love interest and she had a fear of intimacy. This ties in with Kyoko's trust issues and her conflicted feelings towards what she wanted for her father and what her father actually wanted. The description for the card states that the doppel reminds Kyoko of her loathsome past and regrets, with the doppel still being capable of using the illusionary magic that Kyoko can no longer use.
Physically Ophelia can be described in two ways: as a Wǔdàn, which is a female warrior in traditional Chinese opera, and as a candle-headed horseman. Kyoko's magical girl outfit and her fierce personality are certainly the traits of a Wǔdàn. Both the witch and Kyoko wear a long red robe, which is the main body of the doppel itself. As a witch, Ophelia has only the melted stump of a candle and a large flame where her head should be. As a doppel, Kyoko stands on a candle-holder with a large flame coming from the back of her head. Candles are strongly associated with Kyoko's father, as they are a recurring visual motif whenever Kyoko's past is shown. Candles appear next to her father whenever he preaches; when his father hangs himself, the puppet version of him falls and is consumed by flames.
As a headless horseman, she rides across a black steed that searches for something it lost. Kyoko was originally associated with unicorns in the anime series. It's possible that what she is riding isn't a horse, but rather a unicorn that has lost its horn. If a unicorn is a symbol of purity and innocence, this would mean that Kyoko may have lost both before she became a witch. Her doppel version instead has Kyoko riding a candleholder that has the black legs of her witch's horse. Rather than a horse's head, however, it has a pink head of hair that looks identical to her sister Momo's hairstyle. She lost her sister and so she lost her innocence.
In Ophelia's barrier, there can be seen various colored fish swimming through the air. Fish have multiple meanings, with the earliest using a fish symbol to represent the Christian faith. Kyoko's father was a priest of an unknown Christian denomination. Fish can also represent abundance, fertility, fortune, and wealth which are all things that came to Kyoko's family after her father began to become famous from his preaching. Sometimes fish can signify a part of your life that you're not satisfied with. Kyoko was certainly not happy when her father was ridiculed and now she lives in the streets with no family to call her own.
