History Anime / Figure17TsubasaAndHikaru

* FishOutOfWater: DD, especially in the second episode, has a rather hilarious case of this, not helped by the fact that he has to rely on two children (This troper's favourite moment is when he's seen checking out Tsubasa's TV in the background).

* BittersweetEnding: As the end of the anime approaches, the biggest question in the closing few episodes is whether or not [[spoiler:Hikaru will survive. Being as the little energy remaining to her failing body was being spent to keep her alive, in the hope she might be taken back by DD and Oldina for preservation, the entirety of her role in the final battle is ''gruelling'' to watch.]][[spoiler:If Hikaru would have survived, she still would have had to leave Tsubasa behind. But at least she would have lived]].

* DeathOfAChild: Two children die in this show.

* IllGirl: He's never shown to be ill, but [[spoiler:Shou Aizawa]]'s father remarks this about him during his funeral in episode 10.
-->"He was such a happy child; you'd never would have guessed how sick he really was."

''Figure 17'' is an unusual anime, not least in that it seems impossible to fit into a genre. It combines elements of SliceOfLife, with Magical Girl, SciFi, Drama... Also, the creators chose to use thirteen 45-minutes episodes, originally aired once a month, rather than the more standard twenty-six 25-minute episodes once a week. This leads to much gentler pacing, the anime taking time to ''very'' deliberately explore its characters, not to mention animation quality one would normally expect to find only in an {{OVA}}.

* GenreBusting: Slice of Life, Magical Girl, Sci-fi, Horror (dude gets impaled in the second episode, framed alongside such stories like performing a school play written by one of the children). Contains a lot of drama that would alienate children of the protagonist's age yet still deals, very realistically (despite the aliens) with issues a child could struggle with.

** During the school play, we get to see Tsubasa in the role of a DarkMagical Girl, too.

** While not really a MagicalGirl anime, the transformation to Figure 17 by the twins is certainly reminiscent of the MagicalGirl genre, as are some of the plot elements. Her combat style, however, is generally rather different from the typical MagicalGirl, largely involving turning one's limbs into spikes and trying to shove them through the nearest enemy. Any other combat ability is given by technology, such as energy cannons or knives. Combat is also rather more brutal and cringe-inducing than the classic MagicalGirl scuffle.
** During the school play, we get to see Tsubasa in the role of a DarkMagicalGirl, too.

* TheQuietOne: Tsubasa ''in spades'' and the trumph suit.

* RedOniBlueOni: Hikaru and Tsubasa respectively.

* ShrinkingViolet: Tsubasa. Much of her CharacterDevelopment has her moving away from this.

An extremely well-designed anime, with very well-considered and developed characters, and a TearJerker warning throughout -- for both happy and sad reasons.

* InfantImmortality: '''[[AvertedTrope Averted]]'''! Two children die in this show, even though the Maguar put everybody in danger. A Maguar nearly ''strangled'' Tsubasa herself to death several times!

* PlotArmor: [[AvertedTrope Nope]]! See InfantImmortality above.

* SchoolPlay: A particularly enjoyable example, not just due to ( thanks to the 45 minutes an episode format ) the viewers being able to watch what was a pretty enjoyable, original play by Tsubasa and Hikaru's class, but also due to the role the performance plays in the overall plot. [[spoiler:Hikaru wants ''desperately'' to be allowed to stay on Earth to make this one last memory with Tsubasa before DD and Oldina take her back to their home civilisation, and during one scene, where one of the twin princesses ( the play was written by Shou, specifically for the two of them to be the lead characters ) pleads with her sister to remember her, after her memory is wiped with magic, Hikaru breaks down crying, knowing they will soon have to remove all memories of DD, Oldina, the Maguar and herself from everyone they've come into contact with - including Tsubasa.]]

* AdaptiveAbility: Arguably the greatest problem in dealing with the Maguar is the fact that each one adapts countermeasures against the method used to kill the previous one making the next one in sequence all that much harder to kill. As a result, virtually every battle is both brutal and costly and forces the protagonists to come up with still more methods of dispatching the beasts.

* AnyoneCanDie: The Maguar are very dangerous, and all those fighting them come close to being killed by the creatures. Indeed,[[spoiler: one of the two protagonists dies in the end as a result of engaging one]], and [[spoiler: one of their school friends dies in the middle of the series, though not as a result of fighting Maguar.]]

* GoOutWithASmile: [[spoiler:Hikaru]] in the GrandFinale.

* MuggleFosterParents: Tsubasa's father becomes this to Hikaru after modifies his memories to make him believe that he had twin daughters all along and that Hikaru was simply living elsewhere with an aunt.

* Genre-Busting: Slice of Life, Magical Girl, Sci-fi, Horror (dude gets impaled in the second episode, framed alongside such stories like performing a school play written by one of the children). Contains a lot of drama that would alienate children of the protagonist's age yet still deals, very realistically (despite the aliens) with issues a child could struggle with.
