Sailor Uranus is one of the four Outer Solar System Senshi, and the keeper of the Space Sword. She is rarely ever seen without her lover, Sailor Neptune. As a Sailor Senshi, Uranus' tactics (along with Neptune's) can be controversial and morally ambiguous, which puts her at odds with Sailor Moon and the other Inner Senshi - particularly since they can frequently involve sacrificing lives. This includes willing to let the Death Buster's victims die, if their Heart Crystals were the ones they were searching for, wanting to kill Hotaru, because she had the Messiah of Silence within her and betraying Super Sailor Saturn and Super Sailor Pluto in an attempt to join with Galaxia and then double-crossed her.
