  '''Sailor Lethe and Sailor Mnemosyne''' were two [[Sailor Soldiers]] [[Animates]] who appeared only in the manga. They guarded the river outside of [[Sailor Galaxia]]'s palace, [[Shadow Galactica]]. They appeared at the very end of the manga for only one act, Act 48. 
  
  == History ==
  Lethe and Mnemosyne came from war-torn and suffering planets. Galaxia approached them and offered them a chance for new life, one where they would finally find peace. 
  
  Lethe guards the River of Oblivion. She wears a green dress, and unlike Mnemosyne, has a cold, dead look to her eyes. Lethe has light purple hair, tied into four buns that lead into long spiraling ponytails.
  
  Mnemosyne guards the River of Memory. Her dress is purple, and has a much softer look in her eyes. Her hair, too, is light purple, and is tied into four ponytails.
  
  Neither of the two, despite working for Galaxia, are truly evil. All they wanted was peace.
  
  == Story ==
  [[Sailor Moon]], [[Chibichibi]], the [[Sailor Starlights]], and [[Princess Kakyuu]] appear at [[Zero Star Sagittarius]]. Before them is a river of sand and a hooded ferryman in a boat, holding an oar. The figure invites them aboard, and with no other option, the group boards the boat.

  The boat begins to cross the river, but it starts to sink into the sand river, which is turning into water, the River of Oblivion. Sailor Moon is thrown into the water and sinks to the bottom. She turns back into her human form, with [[Image:holdon.jpg|left|thumb|1000px|Lethe protecting Mnemosyne.]]little to no memory. She sees a figure in a green dress, who identifies herself as Lethe, holding [[Luna]], [[Artemis]], and [[Diana]]. Lethe asks her questions about her cats and [[Mamoru Chiba]]. Sailor Moon cannot remember anything, and Lethe destroys the cats. 
  
  Sailor Moon is crushed. She begins to ask why, and how, and who she is. Lethe explains to her that everything that is born must die, and attacks her with the oar. She uses the attack, "Galactica Musotis Alpastonis." Then another girl appears, this one in a purple dress. She reveals herself as Mnemosyne. Lethe attacks Sailor Moon while Mnemosyne watches in anguish. Lethe says she is going to kill Sailor Moon, but Mnemosyne stops her. Mnemosyne believes that Galaxia should make the final judgment on Sailor Moon. Sailor Moon regains her memories and transforms back. She returns to the surface of the river with Mnemosyne's protection. Lethe is angry at Mnemosyne, and believes she's betraying her, but Mnemosyne continues to help the group, including restoring Kakyuu's memories with a drink from her own river, the River of Memory.
  
  The pair introduce themselves to the group and tell their story. They discuss war and wonder if it can ever end. Sailor Moon tells them that she'd give up her life if it meant the end of the war. Lethe tells her not to die, and they help the group find Galaxia.
  
  Suddenly, two shadowed Animates appear atop pillars in the sand. They are known as [[Sailor Chi and Sailor Phi]]. They call Lethe and Mnemosyne useless fools and attack them with their scepters. The two hold eachothers hands and call eachothers names as they disintegrate into ash.
