In the first arc of SailorStars, Neherenia returns to seek revenge on Usagi and the Sailor Senshi for thwarting her plans in SuperS. Breaking her soul mirror, the pieces fall to Earth and enter people's eyes, brainwashing them. This of course happens to Mamoru. The Outer Senshi return to fight as Haruka and Michiru are attacked by Neherenia's minions, and Pluto brings baby Hotaru too since she says they will need her help. Hotaru, using her powers, gives the Outers all power-ups, and she grows rapidly until she remembers her previous life and can transform into Sailorsaturn. When reunited, the powers of all the senshi combine to give Sailormoon her final form, Eternal Sailormoon.
Because of the mirror part in his eye, Mamoru becomes brainwashed by Neherenia, and she kidnaps him. This throws Chibi-usa into a time paradox because with her father gone, she will not be able to be born and thus starts to fade. The Sailor Senshi all go to confront Neherenia and rescue Mamoru; however they all become separated along the way, and each becomes trapped by Neherenia in mirrors. Usagi finally manages to reach Neherenia. It turns out that Neherenia really wanted a friend and was lonely by herself, so she gained beauty from a mirror to gain admiration from others, but once she discovered that she couldn't remain beautiful forever, she turned evil. Usagi feels deep sympathy for her, as do the other Sailor Senshi (all of them are crying), and they break free of their mirrors. Mamoru is freed from Neherenia's spell, Chibimoon returns, and then Sailormoon returns Neherenia to her home to start over, where she wakes up as a small child having a bad dream.
