''Shangri-La'' is a series of science-fiction (with supernatural elements) LightNovels written by Eiichi Ikegami in 2004 and 2005, which was adapted into a manga and an anime by Creator/{{Gonzo}} in 2009. An odd duck if there ever was one, proposing a world driven into poverty by [[http://en.wikipedia.org/wiki/Carbon_tax carbon taxes]], into chaos by [[http://en.wikipedia.org/wiki/Arbitrage arbitrage]] in carbon credits, and awaiting a savior -- in the form of a GeniusDitz MagicalGirl with a PrecisionGuidedBoomerang.

At some point in the near future, the UN tries to stop GlobalWarming by imposing extremely heavy carbon taxes. This has the effect of turning the world economy into one based entirely on the trade of carbon. Meanwhile, an earthquake destroys the entire Kanto region of Japan. Because Japan is now in a horrible economic situation, and the carbon tax hasn't been lifted, Tokyo is turned into an incredibly dense jungle. The plants there are supposed to absorb carbon dioxide from the air, reducing the taxes the country has to pay. Tokyo is rebuilt as Atlas, an enormous tower that can hold millions of people.

But of course, it can't quite hold enough people, so the majority of people have to live in villages in the middle of the jungle, where they're typically treated as second-class citizens by the elite living in Atlas. The organization Metal Age opposes the construction for this reason.

The story focuses mainly on Kuniko Hojo, an 18-year old girl who lives in the city of Duomo, where she was brought to be the leader of Metal Age, even though she doesn't necessarily want to be their leader. Kuniko wants all people to have a higher standard of living, like what she hears Atlas is like, and devotes herself to pursing that goal, by whatever means necessary. And while Kuniko is trying to better the lives of everyone, those in power in Atlas are concerned with a prophecy of sorts, that requires that one of three people eventually inherit Atlas.
!!''Shangri-La'' provides examples of the following tropes:

* AdaptationDistillation: Just compare the original novel's drawings with the anime designs (which include an AdaptationDyeJob for Kuniko).
* AnyoneCanDie: [[spoiler:Miiko, Takehiko, Soichiro, and Ryoko; not to mention all the kids at the detention center.]]
* {{BFS}}: In the final battle, Kuniko uses a boomerang that is several times larger than she is.
* BigBad: Ryoko, of course.
* [[spoiler:BroughtDownToNormal: Miiko removes Mikuni's powers (and her illness) in the final episode.]]
* ButtMonkey: Poor, poor Shion.
* CompanionCube: Karin's teddy bear, Pudding.
* DisneyDeath: [[spoiler:Takehiko, though he pulls a TakingYouWithMe on Soichiro in the final episode. Sayoko ''twice'' in the last few episodes.]]
* EmptyQuiver: MEDUSA [[spoiler:hacks into every country on Earth and attempts to fire every single nuclear missile in the world at the same time, but is stopped by Karin.]]
* EvilTowerOfOminousness: Atlas
* EvolvingCredits: The ending images change halfway through.
* FastTunnelling
* FreakOut: [[spoiler:Karin upon learning that her parents have been dead for ''years''.]]
* FaceHeelTurn: [[spoiler:Takehiko.]]
* FanDisservice: Momoko. Admit it, the idea of a sexy looking female with Creator/JojiNakata's voice is just downright off-putting...
* HeroicSacrifice: [[spoiler:Miiko -- taken over by Hiruko -- shields Mikuni and Sayoko from the Neo Akihabara bombing.]]
* HiddenDepths: As revealed in the prison arc, Tomoka knows a bit more about the situation than what her status has half of ThoseTwoGuys implies.
* {{Hikikomori}}: Karin.
* HollywoodHacking: Hacking attempts are rarely depicted the same way more than once, and every single depiction has remarkably little in common with any computer-related task at all.
* HumanSacrifice: [[spoiler:The continual sacrificing of children is necessary for Atlas to remain standing.]]
* {{Idiot Hero}}ine: "No plan, no idea!"
* KarmaHoudini: Nagiko and Tarsian [[spoiler:created a system of child sacrifice]]. Nobody really seems to mind ([[spoiler:though Nagiko is exiled when Kuniko finds out about her status]]).
* LarynxDissonance: Momoko and Miiko are both transgender. They look like women, but have male voices.
* LivingLieDetector: Mikuni. And in her case, anyone who lies to her is instantly killed, though [[BlessedWithSuck apparently she doesn't do it on purpose.]]
* MagicSkirt: Kuniko (though there are many comments about her underwear, and she gets an almost undetectable PantyShot in the finale).
* MundaneMadeAwesome: Cutting ''the cannon of a tank'' with a frickin' boomerang.
* NotDrawnToScale: Apparently they either couldn't agree on a uniform size for Kuniko's boomerang, or she has a HyperspaceArsenal of boomerangs ranging in size from pocketknives to claymores.
* ObfuscatingStupidity: Nagiko.
* OlderThanTheyLook: Kuniko's 18 as the series begins, though her height and lack of assets make her seem maybe half that.
* {{Otaku}}: The 3 Akihabara old guys.
* PoweredByAForsakenChild: [[spoiler:For Atlas not to be destroyed, Hiruko must be in his room in Atlas. And for this to happen, he needs to take over the body of a maiden, which will end up eventually being destroyed.]]
* PrecisionFStrike: A few of them in the dub throughout the second half.
* PrecisionGuidedBoomerang: Kuniko's weapon of choice is the boomerang. Naturally, this leads to a lot of this trope.
* LaResistance: Metal Age.
* LongLostRelative: [[spoiler:Two examples -- Nagiko and Mikuni (sisters), and Sayoko and Shogo (half-siblings).]]
* RoyalWe: Mikuni.
* SleepModeSize: Until Karin lets him loose, MEDUSA looks like a SuperDeformed snake.
* {{Stripperific}}: Most of Ryoko's outfits are this.
* TalkingIsAFreeAction: The first fight of the anime; apparently Kuniko has enough time to put on some makeup while fighting.
* ThoseTwoGuys: Tomoka and Yuri.
* TheTokyoFireball: Before the beginning of the story, Tokyo was completely destroyed by an earthquake. [[spoiler:And then Kuniko destroys it again later on to stop the Daedalus.]]
* TooKinkyToTorture: Momoko.
* {{Transgender}}: Momoko and Miiko are both transgender woman.
* TheUnfavorite: [[spoiler:This is why Shion always stood by Ryoko -- ignored in favor of his brother Reon in the past, she was the only one who paid attention to him (abusive as it was).]]
* UnhandThemVillain: [[spoiler:Mikuni orders Ryoko to let Sayoko go as they're going up the elevator near the end. Guess how well that goes.]]
* TheVoiceless: Furakawa [[spoiler:until the final episode]].
* WhipItGood: Momoko uses a whip, though she does a lot more tying things up with it and swinging on it than actual whipping.
