THIS ISN’T LAME THIS IS WONDERFUL TERRITORY AND I WENT
TOTALLY OFF THE RAILS, THE ENDING IS DISAPPOINTING BUT CHRIST I WROTE WAY TOO
MUCH.

• I’m going to come from the second season angle, with the
  special act never happening. Also, I think there’s no Chibs in the PGSM-verse,
  because of Sailor Luna and also working in a world without the security of
  Crystal Tokyo is interesting.
• So that puts us with a Pluto who has not known friendship,
  who never fought or died for a sweet little girl. She becomes Setsuna and
  everything is new, she gets to be with people for the first time.
• Also, she’s aged down a bit. Only a little older than our
  main cast. She is so eager to befriend them and she doesn’t know how. And she
  knows she is supposed to be there to warn them, but she wants so badly to be
  loved by them that she frets over her approach and dreads their impression of
  her being such a bad omen.
• Minako notices her, and confronts her, thinking she might be
  a fan going to far, showing up places they hang out and always looking a little
  too long. Setsuna transforms to assure her that’s not the case. She explains
  that there may be a time when additional soldiers are needed to destroy bigger
  threats.
• She also asks that Minako keep her a secret from the others.
• Minako agrees, but she knows what it’s like to take on the
  burden of duty and memory alone, so she invites Setsuna along to hang out with
  them.
• (And as monster attacks start cropping up again, she makes
  sure Setsuna is able to sneak away quietly instead of transforming. There’s not
  yet anything they can’t handle on their own yet anyway.)
• There’s a nice little subplot of Rei getting jealous of this
  new, beautiful older girl Minako is suddenly chummy with.
• She swears she’s not jealous, she explains to Ami one night,
  it’s just that she used to be the one person Minako connected to, and now
  Setsuna’s new and shiny and she feels forgetten.
• That’s jealousy, Ami says (she knows the feeling all too
  well), but what did you say about premonitions of doom?
• Rei says it’s probably nothing. Ami takes note while Rei is
  focused on her definitely-not-jealousy.
• Usagi, meanwhile, is causing Mamoru some
  definitely-not-jealousy as she spends time with a handsome stranger she met in
  a candy shop.
• He of course doesn’t SAY anything, of course, but Usagi sees
  something is wrong and mopes around the karaoke bar trying to figure it out.
• Mako has NO PATIENCE for Mamoru’s shit, so she barges over
  to his place to find out what’s wrong. He caves and she’s just like YOU’RE
  STUPID USAGI LOVES YOU. Also, I think Haruka is about as threatening to you as
  a teddy bear, she cries over every animal video Usagi shows her.
• Oh, is all Mamoru can say, and then he pulls his head out of
  his ass.
• We then get just fun scenes of the girls (including
  Setsuna!) hanging out with Haruka, trying on sunglasses, complaining about
  school, all the usual stuff. She and Mako play basketball. A good time is had
  by all.
• Meanwhile, tho, the viewers get insight into the Death
  Buster’s plans. Tomoe and Kaolintie (the baddies are streamlined a bit) hatch
  daimons from various objects. They whisper about building up to hatching the
  most powerful daimon of all.
• The daimons get more and more powerful, the girls fight more
  and more. One day they get attacked while hanging out, and in order to protect
  Haruka, Setsuna is forced to reveal herself. And when she transforms, she
  recognizes the hidden power of Uranus in Haruka.
• The girls are surprised in the aftermath, but not shocked.
  Usagi is elated that both her new friends are senshi. She offers her hand to
  Haruka, eager to see her transform for the first time…
• And is blown away by a blast of power.
• “That girl will not become a senshi,” says a voice from the shadows.
  “You will not lead her down this path.”
• The audience sees a shot of green hair, a glint of a mirror.
• “We need her to awaken the messiah, should the need arise.”
  Setsuna says. She touches the garnet orb on her staff.
• “Then the need shall not arise,” says the mysterious
  soldier. “If she is with you, she is protected, is she not?”
• Haruka wants to join the fight, but something holds her
  back. And when she asks, later, Minako is honest. Duty is hard. Duty is
  painful. Whoever the mysterious soldier is, she is not wrong. Whatever reasons
  she has for protecting Haruka may be valid.
• Rei, meanwhile, is not content to be left wondering. She
  goes to her fires with a question, and they give her an answer. The next day
  she tracks down the young heiress Michiru Kaioh.
• “I know who you are,” she says, but Michiru does not falter.
  “And I know who you are, Mars. I know what you have seen. Pluto is wrong. When
  we three awaken we bring destruction. I will not let that girl face that.”
• “What is she to you?”
• Michiru freezes. “Everything. But I am nothing to her.” And
  she takes her leave.
• There’s several episodes of Haruka agonizing and the girls
  fighting and Neptune watching from the shadows and Rei being weird about
  Setsuna and Minako and trying to decide if she’s relieved or more threatened by
  the fact that she’s a soldier.
• And finally one episode ends with a scared little girl looking
  into Tomoe’s laboratory, with more ominous talk of The Most Powerful Daimon.
• We follow this little girl, Hotaru, next episode, see her go
  to school and be picked on for being sickly, see her avoid going home. She
  meets Haruka, who asks if she’s lost. She says no, but when Haruka asks if she’d
  like to be walked home because it’s getting dark, she nods and takes her hand.
• Of course, a powerful daimon attacks them.
• Neptune appears seemingly out of nowhere to fight it. “Run,”
  she spits, and Haruka picks up Hotaru and tries but a second daimon appears. “Forget
  the girl and run!”
• Haruka, of course, cannot, and if she cannot run, she must
  fight.
• The power explodes out of her and she transforms. Michiru
  watches in despair.
• Uranus immediately kills the monster she faces with her
  sword, and turns to make sure Hotaru is okay.
• But Hotaru’s glowing purple, and in a voice not her own she
  demands the third. Where is it? She needs the third.
• Michiru drops her transformation, and yells at Haruka to do
  the same. Hotaru returns to normal with no memory of what happened.
• “The three of us must never be transformed in the same
  place,” Michiru says quietly. “Lest the messiah of silence awaken.”
• “You don’t have to be alone though,”Haruka says. (She
  carries Hotaru, who has fallen asleep, on her back.
• Michiru insists it’s too risky. She would rather Haruka stay
  safe, but Haruka smiles and says she’s in this now. She asks why Michiru cares
  so much, and she avoids the question.
• All the senshi, minus Michiru, have a meeting in the karaoke
  parlor. Rei states what she knows, and so does Haruka. The incident with Hotaru
  worries Pluto. She explains that the three of them are supposed to call forth
  the holy grail, which empowers Serenity.
• Usagi quietly says that every power that can do good can do
  bad just as easily.
• It silences them all for a long moment. Then Haruka suggests
  that Hotaru seems troubled, and maybe the best option would be to find out more
  about what might be going on.
• They form a plan. Ami signs up to be a tutor at Hotaru’s
  elementary school. She meets Hotaru, but learns nothing. Hotaru is troubled by
  bullying, that is clear, but there’s something deeper Ami can see but can’t
  define.
• Then, without notice because she’s not one to be behind the
  scenes, MINAKO AINO makes a surprise visit to the elementary school! All of the
  kids go nuts, asking for autographs and songs, but Hotaru hangs back. Ami takes
  her chance and asks Hotaru what’s wrong. She’s been bullied too, she assures
  her, and she won’t tell anyone anything Hotaru says.
• Hotaru is painfully ready to trust people. She tells Ami her
  mother died, but now her father has brought home a woman and the woman won’t
  leave. Ami nods, thinking it’s a stepmother situation, but then Hotaru whispers
  that they spend all their time in the basement laboratory, saying things that
  scare her, and sometimes she wakes up at night sure someone has been in her
  room.
• There’s whispers in her dreams, words she doesn’t understand.
  Daimons. Does Ami know what a daimon is?
• Ami lies and says no. As soon as she can, she takes out her
  phone and makes a call.
• Haruka, luckily, knows where Hotaru’s house is from walking
  her home. The two of them expect to do a stealth attack (figuring there is no
  time to gether the others), but Kaolinite knows Hotaru has talked. She meets
  them at the door and announces they are too late.
• She turns and shoves Hotaru forward, announcing the most
  powerful daimon is complete.
• The wind rises around Hotaru. Haruka whispers that this isn’t
  how she went strange before.
• Michiru runs past everyone, untransformed. As she is about
  to throw herself on Hotaru, Haruka grabs her arm. “What are you doing?”
• “Killing the girl will save us all.”
• “How can you say that? She’s a child.”
• The fight is cut short by Hotaru hatching into Mistress
  Nine.
• The being that was once the little girl Hotaru looks at her
  hands, shrieking with laughter at the joy of being alive. The sky darkens above
  her. She smiles before lashing out.
• Michiru shields Haruka from the blow, looking so small in
  comparision to tall, transformed Uranus.
• Mistress Nine knocks back Mercury, declaring them not worth
  the fight. She calls for Tomoe and Kaolinite, declaring that they must protect
  her, they’ve brought her into a body still to frail to handle her power. She
  cannot yet call Pharoh 90.
• And then Hotaru collapses, a girl once again. Tomoe and
  Kaolinite take her up and disappear.
• There’s a few quieter episodes. Haruka visits Michiru in the
  hospital, and Michiru confesses everything. How her visions had led her to
  Haruka, and while she’d already planned on stopping her from awakening, the
  more she watched, the more she wanted to protect Haruka’s smile. It wouldn’t be
  fair if Haruka had to face a soldier’s life. She never wanted Haruka to face
  down killing a little girl for the sake of the world.
• Once she’s out, everyone comes together. Setsuna somberly
  announces her thoughts—based on what Haruka saw, Hotaru bears the soul of
  Saturn, the soldier of destruction. Michiru agrees, stating the extent of her
  visions. She’s seen that they are between a rock and a hard place—destruction by
  Saturn or destruction by Pharoh 90.
• Setsuna sees things differently. Saturn’s power razes the earth
  as a fire might raze a crop, ensuring the soil is renewed so that it can grow
  back stronger. Destruction by the likes of Pharoh 90 is a plague, poisoning the
  earth so that nothing shall rise up in its wake.
• They should awaken Saturn to force out Mistress Nine.
• Minako agrees. Rei very emphatically does not. They have
  fought for their lives. This life. She’s not prepared to sacrifice it. She and
  Minako fall into old patterns of subordination and accusations of being bad
  soldiers.
• Usagi stops them. They will awaken Saturn. But she will stop
  the destruction. She will not hear that it’s not how it works.
• They draw out Mistress Nine once more, and this time she is successful
  in calling to her master. Pharoh 90 appears in the sky, slowly descending to
  consume the earth.
• The soldiers worry they are too late, but they follow the
  plan.
• The Outers all transform, and Mistress Nine begins to morph.
  There is a war inside Hotaru’s body, and Saturn wins.
• She raises her glaive to reset, but Princess Sailor Moon
  steps up, blocking the glaive with her sword.
• “I will not allow destruction of things I love.”
• “You are too late. I will birth this world anew. I am
  destruction incarnate.”
• “So was I, once.” Usagi fades into her regular Sailor Moon
  form. The Holy Grail appears before her, and she takes it. “We don’t have to be
  the things we were made for.” The grail opens and light washes over her. She
  has become Super Sailor Moon. “I destroyed my kingdom in pain, and I was wrong.”
• “I am not motivated by pain, only duty.”
• “A very good friend of mine felt the same, once. But she
  found out duty isn’t all there is.”
• “There’s nothing else for me!” Saturn yells, sounding much
  more like Hotaru. “This is something I can do, this is the only thing that’s
  right!”
• “No, we can do something else, together.” Usagi holds out her
  hand, and Hotaru takes it, just as she took Haruka’s hand before. Together they
  face Pharoh 90, the power of Super Sailor Moon lifting them up to meet him. They
  disappear to fight him from the inside.
• Usagi emerges, the holy grail cracked in two at her feet,
  and Hotaru, once again an ordinary little girl, in her arms.
