Yuhata Midorikawa

Yuhata Midorikawa is the younger sister to Izumo Midorikawa (of Red Squad fame). Due to her tactical genius, she becomes one of Sidonia's top strategists and promoted to Vice Commander of Sidonia. At the beginning of the series, she is a female, but transitioned into a cybernetic male by the end of the series. Yuhata Midorikawa is relatively short. She wears a cadet uniform instead of a skin suit. Her chin-length hair is dark green like her brother's, as are her eyes, and is styled in a temple bob cut, with two locks of hair on either side of her face being longer than the rest. She has a rather prominent mole on her left cheek, specifically near the cheekbone (although it's placed more lower in the manga). Her wardrobe is consistent, her uniform, although on one occasion she wears a green sweater and shorts on a vacation. She is rather attractive, but her manner of approach to Tanikaze puts him off. Yuhata Midorikawa seems to swing between two completely different personalities, depending on where she is or who's she's with. From the moment she learns about Nagate Tanikaze's encounter with Gauna 487, Yuhata becomes very fascinated, and then infatuated with him. But her obsessive manner makes her a fangirl. She becomes very jealous when he's around another girl, like Izana or Hoshijiro, and goes out of her way to catch him alone. This relationship is very one sided, as Tanikaze seems to consider her a good friend, but is a bit put off by her methods. When Ichirou Seii decides to join Tanikaze's squad, he hires Yuhata to take his place. She objected to the job, as she wanted to be a Garde pilot like her brother, but as Seii put it, he felt that she could replace him with her perception and insight. When on the bridge, or analyzing data, she becomes extremely perceptive, able to form a reasonable conclusion from small amounts of data. Once in the Commander's Aide position, she becomes very adept and effective. However, her feelings for Tanikaze bleed through, and she makes sure his safety is top priority (when it doesn't compromise her job). Yuhata definently plays the part of the youngest child in her family. Her older brother Izumo Midorikawa tries to keep her under control, but she shows to be very determined. She becomes furious when he tries to keep her away from Tanikaze, and she in turn acts very childish and emotional. Her infatuation with Tanikaze takes a new turn when he kills Gauna 487, "avenging" Izumo.
