[[caption-width-right:300:The classic story of [[BoyMeetsGirl Giant Robot Meets Girl]].]]

In 2007, Creator/{{Sunrise}} adapted popular video game ''VideoGame/TheIdolmaster'' into [[TheAnimeOfTheGame an anime]]. This being Sunrise, they didn't exactly take the expected path, deciding to transplant the characters into an {{Elseworld}} RealRobot series.

In the world of ''Xenoglossia'', the moon was destroyed over a century ago by an event known as "Lost Artemis". Because of this, fragments of the moon occasionally fall to Earth and must be destroyed before they can cause serious damage. While most countries use missiles to deal with these "Drops", Japan is bound by the [[http://en.wikipedia.org/wiki/Three_Non-Nuclear_Principles Three Non-Nuclear Principles]] and must instead resort to empathetic HumongousMecha codenamed "[=iDOLs=]".

Haruka Amami is an aspiring IdolSinger who moves to Tokyo following a successful audition, only to end up FallingIntoTheCockpit of one of these [=iDOLs=]. She then discovers that the audition was a front for a secret task force called Mondenkind, who were searching for compatible [=iDOL=] pilots: an [[TitleDrop iDOL-Master]], per say.

While it may seem like the standard fare mecha series at first, it's intertwined with drama from the relationships between the pilots and the mecha.

Has been liscenced by Sentai Filmworks in July 2012, marking the Idolm@ster franchise's first official US release.

For the second anime adaptation of ''VideoGame/TheIdolmaster'', which is faithful to the original source, see [[Anime/TheIdolmaster here]].

!'''This series provides examples of:'''

* ActionGirl: There's quite a few of these, but Azusa of all people takes the cake.
* AdaptationDyeJob -- A few of the girls.
* AdaptationalCurves -- Chihaya (From 72cm to 87cm), Yukiho (80 to 88, making her the bustiest member of the show's cast) and Yayoi (From 72 to 87, going hand in hand with her being at least four years older than her game counterpart). Inverted for Azusa, who was downsized from 91cm gamewise to a more modest 86 cm.
* AllJustADream -- Discussed. In the last episode, one of the characters jokes that the Earth was actually destroyed more than a century ago and they're living in a dream. Obviously, no one is amused.
* AngstySurvivingTwin: [[spoiler: Ami, when Haruka first meets her.]]
* BadassAdorable -- Makoto retains this quality from her game incarnation. Haruka gains a bit of this quality as well and Iori steps up to it later on. [[spoiler:Yukiho is also revealed to be one.]]
* BadassInANiceSuit -- Joseph Shingetsu, as revealed during the retaking of Mondenkind Japan by the iDOL Team, wherein he uses GoodOldFisticuffs to take out soldiers wearing body armor and helmets... ''with his bare freakin' hands''.
* BeachEpisode -- Episode eight.
* BetweenMyLegs -- Of Iori in episode 3.
%%* BlandNameProduct

%%* BridgeBunnies
* CloningBlues -- [[spoiler:R.I.F.F.A]]
* ClingyJealousGirl -- [[spoiler:Chihaya, Imber's old pilot, wants to be "one" with him. In later episodes, she goes full on {{Yandere}}]]

* DifferentAsDayAndNight [[spoiler:The Futami twins, as revealed when Mami returns in the later half of the show. Ami is gentle and reserved while Mami is a GenkiGirl.]]
%%* {{Elseworld}}
* EmpathicWeapon -- The iDOLs themselves sync with a pilot (or two, in the case of Nebula), and their performance depends on how "compatible" they are with each other. However, the pilot has to maintain a relationship with the mecha. Should the pilot treat the iDOL irresponsibly, the iDOL will drop in performance, its trust in the pilot diminished. [[spoiler: The iDOLs are even capable of rejecting an irresponsible or untrustworthy pilot.]]
** The iDoLs are even capable of acting on their own, from small movements to [[spoiler: punching another mech in the face to even an old debt.]]
* EnfantTerrible -- R.I.F.F.A. [[spoiler:Dialed UpToEleven with the reveal that there's a whole army of her late in the series and that they seem to ''love'' smashing people's heads in with [[GirlWithPsychoWeapon axes]].]]
* EverythingsBetterWithPenguins -- There's a whole penguin motif running through the show, and of course, Yayoi's giant penguin suit.
* ExtyYearsFromNow -- Averted in the case of "Lost Artemis", the moon's destruction ''107'' years before the series.
* EvilIsPetty -- The reason why Karasu is TheManBehindTheMan for Turiavita and is responsible for no small amount of misery during the show's run? [[spoiler:The Grand Lodge Cats kicked his father out of the group some time before the series began, thus denying Karasu himself the chance to become a member.]]
* FaceHeelTurn -- [[spoiler:Makoto undergoes one following rejection by Nebula halfway through the series' run when she believes that Azusa doesn't care about her.]]
** HeelFaceTurn -- [[spoiler:Makoto returns to the fold during the assault on Turiavita in the penultimate episode, having sorted out her issues with Azusa right before the latter's death.]]
* GeniusBruiser -- Joseph Shingetsu is a man of intelligence and refined taste who enjoys brewing coffee and collecting laquerware... He's also a master of GoodOldFisticuffs, as revealed during the retaking of Mondenkind Japan.
* HeroicSacrifice [[spoiler:Nubilum makes his in episode 25, protecting Yukiho and Haruka from Vulturius. Imber and the other remaining iDOLs follow in the finale to save the world from Aulyn.]]
* HonorBeforeReason -- In order to deal with the threat of falling rocks from the sky, every other country in the world had equipped themselves with tactical missiles. However, Japan, in order to honor the post-war agreement, decided not to use said missiles, and instead sends girls in giant robots to go up into orbit and ''punch'' the rocks into dust.
* HotBlooded: This show's take on Iori.
* HumongousMecha -- The iDOLs [[spoiler:And the knockoff Epimetheus units mass produced by Turiavita.]]
* IdolSinger -- Sort of. Musical terminology is used in conjunction with the mecha to remind viewers of the roots of the series.
** Not to mention Yayoi is an idol before the series even starts (as well as Ami Futami, though she isn't introduced until later on in the series), and Haruka eventually becomes one [[spoiler:due to trying to cheer Imber up and actually being scouted in the process. She still has this job at the end of the series.]]
%%* ImprobablyFemaleCast
* InNameOnly -- The show has very, very little in common with the videogame it is based off of.
* KillSat -- Vulturius. [[spoiler:It's a failsafe prepared by the Grand Lodge Cats council in order to eliminate all of the iDOLs before they can awaken Aulyn.]]
* KilledOffForReal -- [[spoiler:Karasu and Lo-Wu in episode 24. Chihaya, Azusa, R.I.F.F.A. (all of them), TheOmniscientCouncilOfVagueness and Nubilum in episode 25. Nebula, Hiems, Tempestas and Imber in the finale.]]
* LikeThatShowButWithMecha -- Considering the source games have nothing to do with mecha.
* LockedOutOfTheLoop -- Yayoi. [[spoiler:Until the last episodes.]]
* MarsNeedsWomen -- Who says girls and giant mecha can't fall in love?
* TheMole -- [[spoiler:Yukiho infiltrated Mondenkind on orders from Chihaya to help her get Imber back. Saku on the other hand is working for the Grand Lodge Cats to disrupt both Mondenkind Japan and Turiavita.]]
** BecomingTheMask -- [[spoiler:Subverted. Yukiho completely goes through with her duties as TheMole, and it isn't until after everything's completely over with that she (presumably) goes back to being friends with Haruka and the others.]]
* ObstructiveBureaucrat -- Hibiki Saku, an advisor from Mondenkind central command who generally acts weaselly and comes up with increasingly sneaky ways of trying to screw over the iDOL team. [[spoiler:This is because he's actually a HiddenAgendaVillain working for the Grand Lodge Cats.]]
* OlderThanTheyLook -- Because of the experiments made on their bodies, [[spoiler:Chihaya and Azusa]] are actually 48 and 51 years old respectively despite looking very young.
* OneDialogueTwoConversations -- Haruka discusses her new job with Yayoi, and her "classmate" who she spends a lot of time with. Yayoi, not knowing said classmate is actually a giant robot, is surprised when Haruka says that her boyfriend let her "ride him".
* ParentalIncest -- Azusa is revealed to have had a relationship of this sort with her adopted father, Kaien Lo-Wu.
* PosthumousCharacter -- [[spoiler:Futami Mami, Ami's twin sister.]]
** [[spoiler:NotQuiteDead -- Two-thirds of the way through, we find out that Mami was alive, held inside Tempestas the whole time.]]
* [[PuppetKing Puppet Queen]] -- Teru Lo-Wu is nominally the head of Turiavita, and most of its members appear to be aligned with the group out of loyalty to her. However, she's actually catatonic for most of the series and Karasuma is the one pulling the strings.
%%* RecycledINSPACE
* SpellMyNameWithAnS -- The correct romanization is R.I.F.F.A, but most people use Riffa.
* ThemeNaming: The iDOLs are named after lunar maria.
* TookALevelInBadass -- Iori started the series as a ButtMonkey. By the endgame she's made the FoeTossingCharge her personal specialty and kicks seven flavors of ass. To the point where her former rival Makoto acknowledges her skills as an equal.
* {{Tykebomb}} -- R.I.F.F.A [[spoiler:And all of her many, MANY clones.]]
* WomanScorned -- Chihaya '''really''' didn't take Imber's rejection well.
