Yuki technically doesn't have a last name, but she's a sexaroid by designation (a throwback reference to character creator's earliest work of the same name, and a term for the kind of robotic humanoid she's a part of.) She's the medical officer for Sirius Platoon.  Her behavior doesn't really give away her robotic origins, but for a good part of the first season, she doesn't 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.  Yuki's personality is generally calm and somewhat withdrawn, but not without a certain sense of curiosity. (Especially after the aforementioned incident.) She doesn't 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.

The story begins on planet Destiny, which claimed to be where the center of the Universe is, where all the terminals of "The Galaxy Railways" are gathered. The main character, Yuuki Manabu (20 years old), carrying on his dead Father and Brother`s will, joined SDF (Space Defense Force) to protect the safety of the Galaxy Railways. SDF, in order to uphold the reputation of maintaining the best transportation schedules within the Universe, deals with accidents, natural disasters, rescue operations, space pirates along all lines of the railway. Layla Destiny Shura is a mysterious beauty unifying SDF and all lines on The Galaxy Railways. 
She possesses the ability to see the destiny of planets, human beings and living things. Even though possessing such powers, she, being a "Guardian of Destiny", is unable to tell passengers leaving this station what difficulties lies ahead of them. However, appearances of those who uses evil powers to change the destinies of these travelers triggers another of her hidden ability. "Destiny is changed by the individual`s oneself. Tomorrow`s happiness is grabbed by the individual`s own hands." In what manner will Yuuki`s destiny be seen by Layla? And, how will Yuuki deal with his destiny amidst the greatest crisis approaching The Galaxy Railways?
