Alice is an OrdinaryHighSchoolStudent and FriendToAllLivingThings. One day, as she's serving as the BadlyBatteredBabysitter to the neighbor's trip-and-a-half of a boy, she has a chance encounter with the YaoiGuys from her school class, and in the course of the discussion, it comes out that they've all been having dreams about being alien scientists on the moon studying earth, all in precisely the same continuity.

Eventually, all seven of the scientists at the base are found to have been [[{{Reincarnation}} reincarnated]] as Japanese teenagers. Their base -- and all its weapons -- is still operational, and the seven of them must find a way to balance their obligations from past lives with their new lives on Earth...

!!This show provides examples of:

* AdrenalineMakeover: Alice.
* AdultsAreUseless: Averted for the aliens, basically because they ''are'' adults. On Earth, however... there is just Tamura knowing what's going on and helping the kids.
* AfterActionVillainAnalysis
* AllForNothing: [[spoiler:First off, we discover that Rin actually was trying to destroy the moonbase all along, not use its power to take over the Earth. What's more, we discover that he wants to destroy it because he remembers that Shion built some device on the moonbase and left it running. However, Rin can't remember what the device does, because Shion had already gone insane by the time he built it. Rin suspects it is some sort of doomsday device, and he wants to destroy the base to get rid of it. However in the end it turns out that the device was essentially a tape-recorder, playing an eternal loop of Mokuren's song; causing all the plants in the base to grow erratically and essentially destroy everything in the base. Ooops. Better apologize to Daisuke's brother for trying to drown him.]]

* {{Backstory}}
* BadassNormal: Tamura is not the only one without ESP, but he's the most useful.

* BelligerentSexualTension: Shion and Mokuren. And when they admit to themselves their feelings, they just CannotSpitItOut.
* BerserkButton: Don't hurt Alice in front of Jinpachi. Also don't disparage Shion's past in front of Rin. And if you're Haruhiko, a.k.a. Shukaido, you basically ''are'' Shion/Rin's BerserkButton.
* BetaCouple: Tamura and Ayako.

*** KillTheCutie

* BrokenAce: Shion: he's good-looking, a genius, and has a incredibly powerful sources. He's also so broken that he believes himself unable to love or care for anyone, and that he will never be able to be part of a family or happy because of his issues.
* BrokenPedestal: Alice seems to idealize Shion, then it becomes clear that he's up to no good and the others tell her what a jerk he was.
* TheChainsOfCommanding: Hiiragi, to the point that even his reincarnation (Daisuke) feels bad for the choices made on the Moon.
* CharacterFocus: Especially Mokuren, Shion, Rin and Alice.
* ChekhovsGun: [[spoiler: The videotape with Mokuren singing is crucial in the end as Shion made it play over and over again, leading the plants to destroy everything in the moon's base]].

* TheChessmaster: Rin/Shion.
* TheChick: Alice.
* ChildrenForcedToKill: Shion during his childhood on Tess.
* CrazyJealousGuy: Rin.

* DespairEventHorizon: Shukaido reaches his when he discovers he's already ill and can't take the vaccine.
** Apparently Rin reaches his [[spoiler: when his mother finally broke and told him he is not her son]].

* DieOrFly: Jinpachi when he falls from Tokyo Tower with an unconscious Rin, and Alice too when she has to destroy a psychic barrier.
* DiedInYourArmsTonight: [[spoiler: Mokuren dies in Shion's arms.]]
* DisproportionateRetribution: Shukaido [[spoiler:vaccinates only Shion against a lethal virus, without telling him, forcing him to see his beloved die and to remain stranded alone on the Moon (their home planet was destroyed during a war) for ''nine years''. The reason? Mokuren loves him even if Shion is an ass and a bundle of emotional issues with legs who even comes to ''rape'' her.]]
* DontYouDarePityMe: Shion can hold grudge ''forever'' if he thinks you're pitying him. Just ask Gyokuran.
* DoomedHometown: more like ''doomed homeplanet''...
* DoubleConsciousness: All the reincarnated characters have problems putting a line between the present and the past: Issei falls in love with Jinpachi due to Enju's feelings for Gyokuran; Alice is so scared by the possibility that she ends up blocking the memories; and Rin, being only eight, is slowly being absorbed by Shion's personality.

* EnergyBall: Every fight with ESP seems to involve this.
* EnfanteTerrible: Rin.
* EvenBadMenLoveTheirMamas: Rin tries really hard to shield his mother from what's goingo on. It doesn't work.
* FateWorseThanDeath: [[spoiler: Shion: stuck on the Moon, ''completely'' alone, surrounded by the corpses of his coworkers and the woman he loves, for ''nine years''. No wonder he ends up insane. Oh, and it was someone he ''trusted'' that inflicted this on him.]]
* FightingFromTheInside: [[spoiler: Rin find himself with the desires, personality, and memories of a fully grown man in his head, and considering that his and Shion's goals are opposites, here we go.]]

* FriendshipMoment: Shion cries alone in front of Gyokuran's coffin.
* FromBadToWorse: For the the scientists on the Moon. And for the kids on Earth too.

* GenderBender: After {{Reincarnation}}. Enju, a woman, wished to be reborn a male, so that she could stay close to Gyokuran in the next life without that messy romance stuff getting in the way.

* GirlNextDoor: Every female character except Mokuren.
* GoMadFromTheIsolation: Shion.
* GodivaHair: Mokuren.
* GoryDiscretionShot: We never see how Shion kills those soldiers that tried to kill him on Tes.

* GreenThumb: Mokuren can make plants grow or wither faster than normal with her singing. Not as lame as it sounds. See Lethal Harmless Superpower entry below.

* HeroicBSOD: Alice has one when she remembers that Shion didn't love Mokuren (not true, but Mokuren believed that). All the scientists have one when their ''whole solar system'' gets destroyed in the war.
* HeterosexualLifePartners:
** Enju and Shusuran, to the point that they became PlatonicLifePartners on Earth ([[spoiler:until Issei and Sakura fall in love and start dating]]).
** Issei and Jinpachi, especially [[spoiler:after Issei manages to let go of Enju's love for Gyokuran]].
* HiddenAgendaVillain
* HumanAliens: The aliens look exactly like humans. They're just really small.
* IAmWho
* [[ICantBelieveImSayingThis I Can't Believe I'm Saying This]]: Basically Mokuren's thought when she declares herself to be engaged to Shion, and that she consented when they had sex.
* IGaveMyWord: Why Shion didn't kill himself on the Moon after Mokuren's death.
* IJustWantToBeLoved: In the end, this was Shion greatest desire. Then [[FromBadToWorse it]] [[GoMadFromTheIsolation got]] [[WoobieDestroyerOfWorlds worse]].
* IJustWantToHaveFriends: Mokuren and Alice.
* IllBoy: Haruhiko. He has a weak heart [[spoiler: because he abused his sarches. Using sarches is not good for your health.]]

* JourneyToTheCenterOfTheMind
* TheKidWithTheRemoteControl: With TokyoTower as the remote!
* LethalHarmlessPowers: The [[GreenThumb kiches]] make plants grow by singing. They can also kill them. ''All'' of them, and they actually ''did'', in the past. The [[GreenAesop effects]] were so devasting that they [[DrivenToSuicide killed themeself out of shame]] (which is [[SpaceWhaleAesop why kiches are so rare]]).
** Not to mention that plants growing out of control overnight is pretty scary too. And if you live in a space station with nothin' but vacuum outside...
* LiteralCliffhanger: At the Tokyo Tower. Rin and Jinpachi are ''very'' lucky that Jinpachi managed to teleport.
* LoadsAndLoadsOfCharacters

* LoudspeakerTruck
* LoveEpiphany: The ones we see: Issei realizes his love for Jinpachi, and Mokuren realizes she's fallen in love with Shion.
* LoveHurts
* LoveTriangle: Issei-Jinpachi-Alice (Type 5); Enju-Gyokuran-Mokuren (Type 5); Shion-Mokuren-Gyokuran (initially sort of 7 'cause Mokuren is unsure of her feelings, then type 4)
* MamaBear: Mrs. Yakushimaru is a nice woman, but if she suspects you're a menace to her son Mikuro, she will tear you apart ''with words''.
* ManipulativeBastard: Rin/Shion, however he starts to relies more and more on his powers as he became more unstable due to the struggle between Rin's and Shion's egos.
* ManlyTears: Haruhiko cries quite a lot. Takashi too, but [[TearsOfFear out of fear]], which makes him unmanly.
* MayDecemberRomance: Alice is nine years older than Rin.
* MegaNeko: Averted in the case of Kyaa. Although he is large in comparison to the scientist's species, to a human he'd be the size of a house cat.
* MercyKill: Averted: Mokuren tries to kill Shion so he will not be alone in the universe, but she can not do it.
* MonumentalBattle

Rin's mother [[spoiler: freaks out about Rin's personality changes and tells him he's not her son, leading him to run away]]. Mikuro's biological mother refused him because of his powers when he was five years old.
* ParentalSubstitute: Lian Mode to Mokuren.
* ThePlague: It kills the seven scientists on the Moon.

* RapeAsDrama: Subverted? The ''concept'' is used for Big Drama in this series. However what actually happened [[spoiler: between Shion and Mokuren ]] is moot as everyone is an UnreliableNarrator due to unclear memories heavily influenced by emotions. See [[YMMV/PleaseSaveMyEarth YMMV section]] for details.

* SaveTheVillain: Basically they end having to save Rin from Shion's influence and Shion from himself.
* ShowerOfAngst: Mokuren [[spoiler: after Shino rapes her.]]
* ShrinkingViolet: Alice was one in the first volume. She remains a shy and quiet girl, but she get better.

* TakeOverTheWorld: To Shion this is the only way to stop humans from destroying the Earth.

*** The names are also {{Meaningful Name}}s, since the symbols match their personalities.

* TomboyAndGirlyGirl: Shusuran (tomboy) and Enju (girly girl); Alice (girly girl) and Sakura (tomboy).
* TraumaCongaLine: Shion's whole life.
* UnreliableNarrator: Everyone, due to unclear memories heavily influenced by emotions. They also often state things as fact when they don't actually know the full story, while believing their own statement. (Y'know, like Real People do) Biggest Example: [[spoiler: "Shion raped Mokuren" turns out to be way more complicated than those 3 words]], Also Mega Spoiler: [[spoiler: "Shion wants to destroy the Earth" turns out to be completely off the mark. Especially interesting because Rin also believes this. You would think that would be reliable since he shares Shion's memories, but no]].
* VillainousBSOD

* VisionsOfAnotherSelf
* {{Yakuza}}: Rin manipulates Majima (yakuza) to render Tamura (former yakuza) harmless, and to kidnap Alice. Dr. Mori also has connections with the yakuza.

* WhatTheHellHero: Haruhiko gets a big one from Jinpachi, when he reveals that [[spoiler:Shukaido only inoculated Shion against the virus that was killing them, forcing him to live alone for nine years]].
* WhereAreTheyNowEpilogue
* WholeEpisodeFlashback: All the aliens' story is in flashbacks.
* WillfullyWeak: Gyokuran wears a device that suppress part of his powers.
* WouldntHurtAChild: The heroes biggest problem? Rin is ''eight years old''. They ''don't'' want to hurt him and when they do, they feel horrible.
* WoundedGazelleGambit: Haruhiko pretends to faint while chasing Alice so she will stops running away. Considering that he has a really [[IllBoy weak heart]] it works.
