* BrokenAce: Shion: he's good-looking, a genius, and has a incredibly powerful sarces. 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.

* CoolPeopleRebelAgainstAuthority: Shion, but the costant conflict with authority doesn't end well: [[spoiler: first he was selected (exiled) to go to study Earth by the government; then the other scientists isolate him]]. Mokuren has shades too.

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

* HoYay / FoeYay: Shion is obsessed with Gyokuran. All the girls noticed and say that Shion ''must'' be in love with him.

* FridgeLogic [[spoiler: Okay, so we know the moonbase it continually resupplied by drones clandestinely sent to Earth. This must also be where they get the manga they're reading from.... but their race is only the size of a human's thumb. Are the drones shrinking the manga for them?]]
** And what exactly were they going to do if they'd evacuated to Earth like Shion wanted? Hook up with TheLittles?

* FoeYay: Majima is obsessed about having Mikuro on his side, and forces him to kiss his foot.
** Shion says that he hates Shukaido so much that when in front of him he feels like a girl in love.

* [[DeadLittleSister Dead Little Brother]]: Tamura's younger brother

* IWillProtectHer

** Shion while confronting Mokuren about the rape.

* HairOfGold: Mokuren.

* IJustWantToBeLoved: In the end, this was Shion greatest desire. Then [[ItGotWorse it]] [[GoMadFromTheIsolation got]] [[WoobieDestroyerOfWorlds worse]].

* ItGotWorse: For the the scientists on the Moon. And for the kids on Earth too.

* RapeAsDrama / RapeIsLove: 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.

* RapeAsDrama: The ''concept'' is used for Big Drama in this series. However what actually happened is moot as everyone is an UnreliableNarrator due to unclear memories heavily influenced by emotions. See [[YMMV/PleaseSaveMyEarth YMMV section]] for different interpretations.

* RapeAsDrama: [[spoiler: Shion raped Mokuren. He hated her personality and wanted to destroy her, [[VirginPower as virginity is needed for a Kiche's power]].]]
** Subrverted as they [[RapeIsLove end up falling in love]]. YMMV, as [[spoiler: Mokuren forgives Shion because she is ''already'' in love with him at the time.]]
** Another interpretation of this confusing and unpleasant event is that both were in love and consented when they had sex. But since they didnt communicate this, Shion assumed that Mokuren only slept with him because she was being blackmailed, and that she didn't consent because her VirginPower didn't disappear like it should have. Mokuren was understandably confused and hurt by all of the above, but maintained during the whole story that she wasn't raped.]]

* GreenAesop: The title and overall plot refers to this. "Take care of your planet while you have it, cause you Earth-people still have a chance at redemption. [[spoiler: Unlike us, Space Scientists whose home space-faring civilization self-destructed in war.]]

* [[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 was consentient when they had sex.

* GreenThumb

* LethalHarmlessPowers: The kiches make plants grow by singing. They can also kill them. ''All'' of them, and they actually ''did'', in the past. The effects were so devasting that they [[DrivenToSuicide killed themeself out of shame]] (which is why kiches are so rare).

* AdaptationDecay: Shukaido comes off as a complete bastard in the anime because of this. In the manga, right after [[spoiler: Shukaido injects Shion with the only dose of a vaccine, Shion breaks down and cries in front of Shukaido, and begs his forgiveness for raping Mokuren. Shukaido then has a HeroicBSOD as he regrets his plan to force Shion to live the rest of his life on the base alone. Since he already injected Shion with the vaccine, it's too late for him to do anything.]] However in the anime, this sequence takes place right after [[spoiler: Shukaido informs Shion of his creation of the vaccine]], therefore instead of [[spoiler: telling Shion the truth, he goes ahead with the plan anyway.]]

* JerkassWoobie: Shion.

* ManlyTears: Haruhiko cries quite a lot. Takashi too, but out of fear, which makes him [[WaterWorks unmanly]].

* ClingyJealousGirl (subversion: Rin is a boy)

* {{Determinator}}: Mokuren.

* DiedInYourArmsTonight: 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.]]

* FriendToAllLivingThings

* 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.

** Subrverted as they [[RapeIsLove end up falling in love]].
*** YMMV, as [[spoiler: Mokuren forgives Shion because she is ''already'' in love with him at the time.]]

* ShowerOfAngst: Mokuren after the rape.
