In this story, it's revealed that all of the wars fought over the past 30 years were part of a {{Masquerade}} to keep the public in the dark about an AlienInvasion. The nations of the world are fighting the enormous alien monsters with a number of superpowered creatures called Category D's. One of these is Mana Eimiya, a [[AttackOfTheFiftyFootWhatever 49.46-metre-tall girl]] whose job is to periodically come out of hiding and beat up incoming aliens, apparently with just her bare hands.

Problem is, she's fallen head over heels for a guy 40 times shorter than her - a boy named Makoto Tobita with spiky hair and an obsession with chivalry and being overprotective of girls. Can this unlikely relationship work?

A different kind of BoyMeetsGirl story from Takeshi Azuma, a.k.a. Studio Kimigabuchi (the studio behind ''Anime/NeonGenesisEvangelion Manga/ReTake'').

!!Provide examples of:

* [[AWizardDidIt A Category D Did It]]: Category D creatures are stated to be supernatural in origin, hence why they can defy the laws of physics.
* ACupAngst: Kuumi had quite complex about it. [[spoiler:When investigating sea spirits phenomenon that attacking girls, Jinguuji points out that the monster only attacked girls with B-cup or larger. ''She is not [[OneHitKill amused.]]'']]
* AmericansAreCowboys: Issac Montana [[ExploitedTrope exploits]] this in the beauty contest.
* [[AttackOfThe50FootWhatever Attack Of The]] [[InsistentTerminology 49.46 Meter]] [[AttackOfThe50FootWhatever Whatever]] [[spoiler: In chapter 28, she grows to [[UpToEleven 4946 meters tall]] and, on chapter 29, grew to the size of ''[[SerialEscalation celestial bodies]]'', big enough to hug ''the sun''.]]
* BadAss: Admit it, if you had balls for fighting a monster by letting it eat you, or ''[[spoiler:survived from having your soul devoured by your girlfriend]]'', you're qualified.
* BeachEpisode: Chapter 19.
* BeamOWar: Between Mana and the Kirin.
* BeautyContest: Chapter 20. A winner wasn't declared between the top 2, though.
* {{BFS}}: Senri is a shapeshifter with the ability to turn himself into one of these for Mana to use. And when Mana is supercharged from [[spoiler: eating Tobita]] he turns into an absolutely MASSIVE [[DropTheHammer hammer]] that completely dwarfs Mana.
* BigBad: [[spoiler: [[CuteMonsterGirl Inochi]], the [[MotherOfAThousandYoung Mother of all the D-Codes]] and love interest of Tobita's ancestor.]]
* BigDamnHeroes: Chapter 17 brings a big one: [[spoiler:After Kuumi ventured into the sealed cave of the Kirin and being overwhelmed by its might (She got beaten halfway to death by just a single of the beast's claws), she resigns herself to death, [[IncestSubtext silently admitting her love for Makoto]]; only to witness [[CrowningMomentOfAwesome Mana's hand crashing through the cavern and halting Kirin's surefire killing blow, and Makoto says, riding on Mana's shoulder: "Kuumi, let me take care of this."]]]]
** Although the preceding scenes could measure to be quite [[CrowningMomentOfHeartwarming touching]]. Or [[IncestSubtext quite a tease]].
* BlushSticker: Isaac Montana, who at one point manages to have these AND a LuminescentBlush at the same time.
* ButNotTooForeign: One of Jinguuji's grandfathers is French.
* CatGirl: When Isaac Montana introduces herself to the rest of the class, she comes in wearing a cat suit.
* CrashIntoHello: Averted when Isaac Montana tries to bump into Tobita. He evades and Isaac knocks her head on a street light.
* [[spoiler: CrucifiedHeroShot: Mana in Chapter 27.]]
* CuteAndPsycho: Kuumi Tobita, Makoto's younger sister, is a pretty, young, [[DemonSlaying highly trained youkai slayer]]. She claims to be quite fond of her brother . . . well, her brother's [[BrotherSisterIncest screams of pain]], anyway. For that matter, she really likes Eimiya's [[PsychoLesbian screams of pain]]. (At one point, she tells Makoto that [[spoiler:it would be a terrible shame if their father did the job of exorcising Eimiya . . . because he would do it painlessly]].) In general, it appears that she likes ''anyone's'' [[{{Fetish}} screams of pain]].
* CuteGiant: Mana.
* CuteMonsterGirl: Mana, again. [[spoiler: Inochi]] counts too.
* DefaceOfTheMoon: [[spoiler:First, ''TokyoTower'' is thrown into the moon. And now, during battle with Kirin, Mana's beam attack ''chipped the moon'']].
* DerailingLoveInterests: Kuumi realizes she's fallen in love with [[spoiler: Senri]] just before his HeroicSacrifice. [[spoiler:He gets better.]]
* DoggedNiceGuy: Tobita.
* MrFanservice[=/=]HandsomeLech: Jinguuji. And Senri takes it to UpToEleven levels since his introduction reveals that he once dated 100 girls at the same time. For true love!
* ForeignFanservice: Isaac Montana.
* FreakyIsCool: Jinguuji's attitude.
* FullFrontalAssault: Aside from some [[CensorSteam Censor Clouds]], Mana is naked after her MakeMyMonsterGrow moment.
* GenderBlenderName: The very [[MostCommonSuperpower VERY female]] [[GenkiGirl Isaac Montana.]] [[WebVideo/YuGiOhTheAbridgedSeries In America!]] Subverted in that [[spoiler: it's not her real name.]]
* GenreSavvy: Isaac Montana and Jinguuji.
** ''Definitely'' Jinguuji. Though initially jealous about Isaac's attempted CrashIntoHello, the fact that he recognized it as a trope clued him in that there was something fishy about it.
* HeroicSacrifice: Tobita (and everyone else except Mana) believed that he was doing this [[spoiler: when he tricked Mana into swallowing him just long enough for her to defeat the MonsterOfTheWeek. It SHOULD have killed him instantly, but [[DisneyDeath it turned out that the B.S. "three minute rule" he made up on the spot worked for him.]] Of course, with the current situation, this might be turned into ''real'' Heroic Sacrifice.]]
** [[spoiler: A flashback shows him doing this to save Kuumi from a bear when they were younger, nearly getting killed in the process.]]
** [[spoiler: After confessing his love to Kuumi, Senrei transforms into his true form and sacrifices himself to kill all but 15 of the 100 massive D-code monsters sent by Inochi... [[SubvertedTrope until it's revealed he possessed Kuumi's doll]].]]
** [[spoiler: Montana [[TakingYouWithMe attempts to blow herself up using a buttload of grenades and dynamite]] [[YouShallNotPass to stop the US army from catching Tobita]]... [[SubvertedTrope but Kuumi stops her]].]]
** [[spoiler: Tobita gets hit by a shell trying to save Mana, causing her to go into a HeroicBSOD and then into a RoaringRampageOfRevenge against Inochi.]]
*** [[spoiler:Of course, she's going on rampage after Tobita ask her to swallow him whole, [[EleventhHourSuperpower overcharging her in the process.]]]]
*** [[spoiler:Then Mana ends up doing this, using all her power to stops Inochi, after ditched Tobita to safety after her heart-to-heart talk and LoveConfession to Tobita.[[DisneyDeath She survived...]] [[TraumaInducedAmnesia at the cost of her memories.]]]]
* HotBlooded: Tobita, again.
* HourOfPower: Subverted. Mana is told that she has three minutes to [[spoiler: spit up Tobita after eating him]], but that was a complete lie. In reality [[spoiler: Tobita should have died the instant Mana swallowed him. No one knows how he survived for any length of time, so for all we know he could stay in for a lot longer that three minutes.]]
* HugeSchoolGirl: At 49.46M, Eimiya is easily the hugest.
* InsistentTerminology: Mana hates it when people round up her height to 50M instead of 49.46 because, according to her, [[ComicallyMissingThePoint short girls are cuter.]]
* InterspeciesRomance: Although Mana's mind and soul are those of a human girl.
* JerkassFacade: Chapter 17 reveals [[spoiler: that at least as far as her brother is concerned, Kuumi's {{Yandere}} attitude is largely a front developed after he got [[BearsAreBadNews mauled by a bear]] trying to protect her. She doesn't want to have him put his life on the line like that ever again.]]
* [[spoiler: {{Kitsune}}: Senri's true form.]]
* LateForSchool: Issac Montana does this intentionally to try to get Tobita's attention, due to learning this from Animes.
* MagicalGirlfriend: Mana is something of an example.
* MagneticGirlfriend: Par for the course, Tobita starts attracting love interests almost immediately after officially becoming Mana's boyfriend. It's both Lampshaded, by Jinguuji lamenting it, and PlayedWith as it's Tobita defending Mana and declaring her to be his girlfriend that makes Akemi realize Tobita's [[IncorruptiblePurePureness true nature]].
* {{New Transfer Student}}s: Mana, Kuumi, and Isaac.
* NobodyPoops: Discussed in chapter 4, Mana acually doesn't poop since she doesn't require food to live.
* NotQuiteHuman: Mana is an enormously obvious example, being merged with a giant youkai.
** [[spoiler: It's also hinted that Makoto isn't entirely normal either, both when he survives having Mana absorb energy from his soul and when his demon-hunting sister says that she loves his screams of pain the most.]]
* NotWhatItLooksLike: After apparently being replaced by [[SmugSnake Senri,]] Tobita is approached by a normal girl he'd saved in the past, who offered to cook for him (something Mana obviously couldn't ever do.) While at her place, not only does Mana see them by looking in the window, but runs off crying about how Tobita "likes little girls." Though in the way she says it, sounds like he is a {{lolicon}}.
* ObfuscatingStupidity: Isaac Montana's American GenkiGirl {{Otaku}} personality masks the fact that she's [[spoiler: TheMole, though Jinguuji is DangerouslyGenreSavvy enough to see through it.]]
* OddFriendship: Jinguuji and Tobita. Maybe because unlike [[HorribleJudgeOfCharacter others]], Jinguuji can really see Tobita for [[DoggedNiceGuy what]] [[NaiveEverygirl he]] [[IncorruptiblePurePureness is]].
** It got better; It's revealed in chapter 38 that Makoto is the first guy who befriend Jinguuji, and he dyed his hair for him.
* OhCrap: End of chapter 20. [[spoiler:"This is The International Space Station. We... we can hear someone. We discovered an immense number of space life-form armies, exceeding the level of Kirin. Their expected destination is... '''EARTH.''']]
* OjouRinglets: Shintani Ryouko.
* {{Otaku}}: Jinguuji, of all people, later joined by Isaac.
* PintSizedPowerhouse: Makoto Tobita, taking out people bigger than himself since elementary.
* TheReasonYouSuckSpeech: Jinguuji delivers one to Inochi, telling her bluntly that her actions contradict Shingon true dreams. [[VillainousBreakdown She doesn't take it well.]]
* ShoutOut
** Jinguuji said he only liked [[LightNovel/HaruhiSuzumiya hyperactive girls who are interested in espers, time travelers or aliens]].
** Emiya's time to fight before she absorbed Tobita's soul completely: [[Anime/NeonGenesisEvangelion three]] [[Series/{{Ultraman}} minutes]].
*** Not to mention monster's design.
** Emiya's fight with [[VisualNovel/SchoolDays Saw.]]
** Emiya's secret technique: [[Series/{{Ultraman}} Crossing-hand Laser]]
** When following Tobita and Isaac into Akihabara, Jinguuji dresses up as a parody of [[Anime/CodeGeass Zero.]]
* ShowWithinAShow: Isaac's favorite anime, ''Beat The Little Mice''.
* SmugSnake: Senri, who lords it over Tobita how much better suited he is for Mana.
* SociopathicHero: Kuumi does a lot to protect the people of Japan from youkai... but let's just say it's not for the purest of reasons.
* SwallowedWhole: Mana eating Tobita.

* [[TinyGuyHugeGirl Tiny Guy, HUGE Girl]]: TheSeries
* TokyoTower: Knocked ''to the moon'' along with a monster.
* TykeBomb: Montana and [[spoiler: Mana]].

* {{Youkai}}
