She has a split-personality named Geminine who is aggressive and focused on avenging her master but honors the samurai code. Geminine was supposed to be a living person, however Gemini was the only one born and is described as having two hearts in one body. Geminine sometimes dominated the body when she was training with her master, though Gemini herself never knew of her existence until she got to New York where Geminine would dominate the body more often (which is mostly due to Gemini's depression). She has a white horse named Rally (Larry in the English-language version) that she keeps in her apartment but will occasionally ride him around New York. Gemini wields both a katana and a Colt Single Action Army revolver. Gemini is the main character of "Sakura Wars V: Episode 0" as she saves Texas and makes her way to New York.
