Sailor Saturn
Besides her relationship with Michiru, Haruka is also close friends with Setsuna Meioh, because the three of them work closely together. Following the destruction of the Death Busters and the rebirth of Sailor Saturn as an infant, they vow to be her family and care for her. Later story arcs show that the four live together happily for some time. Nothing about Haruka's family life is ever discussed, although she and Michiru appear noticeably wealthy by unknown means. In the manga, Haruka says that she and Michiru have "wealthy patrons".
