Michiru is the recarnation of the Princess of Neptune, and transforms into the Elegant Fighter, Sailor Neptune. Michiru is a quiet, artistically inclined young woman with a soft sense of humor. She holds herself elegantly, which attests to her beauty, and is from a wealthy family. Her mannerisms can be described as mature, lady-like, or worthy of a princess. As Michiru, her empathic principles often predominate. As Sailor Neptune, however, she tends to be more rigid and distant. Her coldness may stem from being a Sailor Scout. Michiru attends tenth grade at Mugen Gauken High with Haruka. She plays the violin professionally and enjoys painting and swimming. Michiru owns a mansion by the sea, and enjoys visiting aquariums and art galleries. Haruka and Michiru share a special romantic bond, though they will not admit to the other Scouts that they are lovers. Sailor Neptune saves Uranus's life a number of times by putting her own on the line to protect her beloved. Michiru is more passive than Haruka, but is certainly not any weaker, either as Michiru or Sailor Neptune.
