Dark Yuki

Dark Yuki is a physical manifestation of Yuki Jojima's darker emotions as well as the eleventh Horoscopes, the Gemini Zodiarts. The only difference between her and the real Yuki is the fact that she has a white mask on her face.

Personality
As an 'evil twin' version of Yuki, Dark Yuki is cruel and calculating. She causes incidents which leave the real Yuki to blame in order to make her source material look bad. She also has a desire to replace the real Yuki in order to become more real.

Abilities
In her human form, Dark Yuki possesses the same traits and knowledge as the original. As the Gemini Zodiarts, having an unorthodox fighting style, she is armed with several cards that function as explosives: Red cards known as Lynceus (リュンケウス, Ryunkeus) that explode on contact and the blue cards called Idas (イーダス, Īdasu) that have a delayed effect. Her Supernova ability allows the Gemini Zodiarts to produce a clone of herself that doubles as a living explosive.

History
Dark Yuki came into being when the Leo and Libra Zodiarts forced Yuki to activate a Zodiarts Switch. Because Yuki was not entirely into the idea, only her darker emotions accepted it and they became Dark Yuki. Dark Yuki would then go on to frame Yuki by pushing Miu and injuring her with what the rest of the Kamen Rider Club thought was jealousy.

Etymology
An alternate romanization of Yuki Joujima's name is "Yuuki Jousima", which is an anagram of "I am Soujikyuu". Sōjikyū is Japanese for the Gemini Constellation.
