is a sweet and lonely young girl. A laboratory accident in her youth significantly compromised her health. After overcoming the darkness that has surrounded her family, Hotaru is able to become Sailor Saturn, Guardian of Silence, Destruction, and Rebirth. She is often pensive, and as a human has the inexplicable power to heal others. Sailor Saturn's weapon is her Silence Glaive, which gives her the power to generate barriers and destroy a planet. When she uses that power, she kills herself but is reborn afterwards by Sailor Moon.
