Yuki

Yuki technically doesnt have a last name but shes a sexaroid by designation a throwback reference to character creators earliest work of the same name and a term for the kind of robotic humanoid shes a part of. Shes the medical officer for Sirius Platoon. Her behavior doesnt really give away her robotic origins but for a good part of the first season she doesnt really consider herself much like a human thus avoiding some human mannerisms like socializing instead choosing to live solely for her duty as the medical officer of the Big 1. However after having her life saved by Manabu while chasing down a group of wanted criminals she allows herself to be persuaded to take part in social events. Yukis personality is generally calm and somewhat withdrawn but not without a certain sense of curiosity. Especially after the aforementioned incident. She doesnt hold her own life much of value and are prone to making rash decisions in situations of emergency whenever a humanoid life is threatened dismissing her actions with the reasoning that she can be replaced if something were to happen. Nevertheless she seems to enjoy her work and she did once profess that she had a certain affection for Manabu whom looked like someone she had known in the past possibly her creator.
