->''"As for science, it may be negative. However, do not forget the thing that there is a scientific side in all the one. The important one is true. Of me the ruler my fate, and me also the commander of my soul."''

The year is 2019. The setting is Tanegashima high school.

''Robotics;Notes'' follows Kaito Yashio, an avid fan of {{Fighting Game}}s who is ranked fifth in the online game Kill-Ballad. Along with Akiho Senomiya, he is a member of his school's robotics club. The club's purpose is to complete a working copy of the HumongousMecha Gunvarrel, the titular character of a wildly popular ShowWithinAShow anime, started by Akiho's sister, Misaki. However, keeping the robotics club afloat is not easy. Kaito and Akiho are the only members and Akiho makes extraordinary budget demands to the school. Thus, the vice-principal offers them a condition: they must win the Robo-One tournament to obtain the desired budget.

Amidst their efforts to create a working HumongousMecha for an upcoming expo, Kaito comes across Subaru Hidaka, a [[SempaiKohai younger high school student]] who has his own fascination in mecha, Frau Kojiro, the {{Hikikomori}} genius programmer of Kill Ballad, Junna Daikoku, the granddaughter of the local robotic parts shop who's ironically nervous around robots, [[VisualNovel/SteinsGate Nae Tennoji]] the young engineer of JAXA who provides funds for the club, and a human-like AI named Airi, who leads him to the mysterious Kimijima Reports [[StoryboardingTheApocalypse that detail how and why a world-altering disaster]] may be on its way...

The {{Sequel}} to ''VisualNovel/SteinsGate'', the game was released on the PS3 and Xbox360 on 2012. In typical visual novel fashion, the story features branching paths and MultipleEndings depending on the player's choices. ''VisualNovel/SteinsGate'''s Phone Trigger system is replaced by the Pokecon Trigger, which activates Kaito's tablet computer, allowing the player to utilize its applications.

An {{animated adaptation}} by ProductionIG began airing on Fuji Tv's {{Noitamina}} slot on [[Fall2012Anime October 2012]], which can be seen on {{Hulu}}. Five manga have also been produced.
----
!This visual novel provides examples of:

* AlternateRealityGame: In-universe. The things that Kaito has to do in order to unlock the Reports, and the Reports' contents, are very much like a real-life ARG.
* ADayInTheLimelight: Junna gets one in episode 12, which explores her past and why she's so terrified of robots after one of her grandfather's robots falls and traps her, along with the regret her grandfather experienced as a result of the accident.
* AdultFear: There are a few.
** [[spoiler:Mizuka's]] death was pretty tragic, especially when you watch Kaito desperately doing everything in his power to try and save her.
** Akiho and Misa. An older sibling has cut off ties from their family with no explanation and ignores any and all attempts at contact, and the last conversation they had with the younger was them [[BreakTheCutie calling her plain and saying she'd never accomplish anything.]] Then it's revealed [[spoiler:the VirtualGhost of an MadScientist she killed to save them is not only [[GrandTheftMe possessing her]], but threatening the lives of everyone Misa cares about unless she cooperates with him]]
* TheAllegedCar: Well, it's technically a mecha, but evoked in episode 9 when the Robotics club attempts to move Gunbuild 1 for the first time. Though expectations from the audience is high, it ultimately barely takes a step before the engine breaks down.
* AmbiguousDisorder: Elephant Mouse Syndrome
* AnimeOfTheGame
* AugmentedReality: [=GunPro-2=] uses AR to overlay an image of Gunvarrel over the robot.
* AuthorExistenceFailure: An in-universe example when [[spoiler:Frau reveals that the reason why the final episode of Gunvarrel was never aired was because the entire production crew was murdered (It was revealed in episode #14, that it was actually self-defense, the other crew-members were brainwashed and tried to kill her). However, this information was kept secret from the public.]]
* AwesomeButImpractical: The fatal flaw of building GunPro-1.
* BasedOnAGreatBigLie: Based on the [[TheOmniscientCouncilOfVagueness Committee of 300]] conspiracy that a secret organization controls all the world's politics, economy and owns a secret military. The Committee is also known by other names such as the "Hidden Hand" or "The Olympians."
* BigBad: The Committee of 300 [[spoiler: and Kou Kimijima]]
* BigDamnHero:
** Nae is surprisingly a {{Badass}}.
** Tarou, Sumio's ''parrot.'' '''[[NotMakingThisUpDisclaimer Seriously.]]'''
-->''[[CloudCuckoolander She ain't chesty!]]''
* {{Blackmail}}: How Kaito makes Subaru Hidaka (aka [[spoiler:Mr. Pleiades]]) joining their club and stops it from being disbanded.
* BlandNameProduct: [[YouTube ShareVideo]] and [[{{Twitter}} Twipo.]] Also [=PhoneDroid=] Pad for iPad. [[{{Imageboards}} @channel for 2channel.]]
* BoringButPractical: Subaru's argument on why aesthetics have to be sacrificed in order to build a funtional giant robot.
* BrainUploading: [[spoiler: Kimijima Kou did this.]]
* BuxomIsBetter: Irei.
* CatGirl: Need an augmented reality version of this trope? [[{{IOS}} There's an app for that!]]
* CallingYourAttacks
-->''(while in the tournament)''\\
'''Kaito''': ''Could you please not shout out the attack names, Aki-chan?''\\
'''Akiho''': ''Eh?! Special moves are meant to be yelled out!''
* CaptainErsatz: By far, ''Gunvarrel'' looks like a love letter to every HumongousMecha show ever made, but it practically is Franchise/{{Gundam}}. YoshiyukiTomino would be ''proud''.
* TheCavalry: [[spoiler: ''Everyone'', even the school's uptight principal comes to the club's aid in episode 20.]]
* CerebusSyndrome: Similar to ''SteinsGate'', shit hits the fan midway through the series, starting at around episode 14 and hitting in full force in episode 16.
* CharClone: Mr. Pleiades.
* ConspicuousCG: The Anime ''was'' animated by Production I.G after all. But special mention goes to the door of Akiho's room opening and closing in episode 5.
** [[spoiler:The replica Gunvarrel in episode 21, it becomes hand-drawn the following episode.]]
* ContinuityNod: [[spoiler:Several Steins;Gate and Chaos;Head characters reappear, such as Nae and Daru ending up working for JAXA.]]
** In the first episode, a mysterious girl appears and says, "Whose eyes are those?"
** Episode 19 has lots of them and they're plot relevant ! Such as the [[spoiler: [[VisualNovel/ChaosHead NoAH machine]] ]]
** According to the introduction, this takes place in the [[SteinsGate 1.048596% divergence]].
** In one of the spinoff mangas, Frau is apparently online friends with Kurisu.
** Kai is also able to become online friends with [=DaSH=] , [=KuriGohanandKamehameha=] and Neidhardt. All which are the online handles of previous characters in the series.

* CryCute: Junna in episode 12, after seeing that people aren't scared of Gunbuild 1 at all.
* DarkAndTroubledPast: Most of the main characters have one.
** Kaito and Akiho [[spoiler:were involved in a mysterious event where they mysteriously fainted, and were then afflicted with debilitating medical conditions that can affect their perception of time. These have been dubbed as "Elephant-Mouse Syndrome": Kaito perceives several seconds as a few minutes, while Akiho perceives five minutes as a few seconds.]]
** Subaru [[spoiler:has an [[AbusiveParents abusive father]] who forbids him from getting involved with robotics and tries to force him to become a fisherman like him.]]
** Frau [[spoiler:lives with the stigma of being the daughter of an accused murderer. Her mother allegedly killed the entire production crew of the Gunvarrel anime and then disappeared (It was revealed in episode #14, that it was actually self-defense, the other crew-members were brainwashed and tried to kill her).]]
** Jun [[spoiler:was traumatized when one of the robots her grandfather built fell on top of her, resulting in her fear of robots and the belief that her grandfather hates her.]]

* {{Defictionalization}}: InUniverse as well.
** Akiho is determined enough to perform this for Gunvarrel.
** [[spoiler:The "Grand Obelisk", the elevator from the GainaxEnding of Gunvarrel, ends up near the location where the Robotics competition is held. It apparently is very hard to tell whether or not it is real or not, considering the ''[[GiantSpaceFleaFromNowhere size of the damn thing]]''.]]
* DespairEventHorizon: Tetsuharu in episode 12, after he gets sick and ends up in the hospital. He seriously considers closing his shop, but is ultimately convinced to keep it open after seeing the Robotics club fixes up his old robots, and more importantly, Junna is slowly working to overcome her fear of them, particularly the one that fell on top of her. He then regains his usual cranky demeanor, along with a renewed hope to carry on his work.
* [[spoiler:DistantFinale]]: [[spoiler:In the epilogue, it's implied that Kaito becomes an astronaut and Akiho manages to build a working replica of Gunvarrel years after the events of the series.]]

* DueToTheDead: [[spoiler: Kai, Aki and Mitchie mourn Irei's death. Mitchie also performs a LibationForTheDead.]]
** [[spoiler: Misaki also pays her respects to Irei, even while being Kimijima's MeatPuppet.]]
* EatThat: You can purchase information from Irei Store by clearing a challenge: eating a nikuman (a Japanese dough bun) with an unusual, typically infernally bad taste.
* {{Engrish}}: Gunvarell, most likely (or intentionally) a corruption of "gunbarrel", the name for the in-series mecha animé and robot.
* FoolishSiblingResponsibleSibling: Akiho and her older sister, Misaki.
* {{Foreshadowing}}[=/=]BrickJoke:
** Episode 4
-->'''Akiho''': "So If I also defeat you (at ''Kill Ballad''), I'll be your superior?"
-->'''Kaito''': "I guess, but I doubt you could ever win, even in a hundred games..."

** Episode 7
-->'''Misaki (young)''': ''You need to grow up to be a man with the "[[Film/TheRightStuff right stuff]]"!
* FriendlyTickleTorture: Nae does this to Kaito in episode 13 when he jokes about her age.
* FunnyAneurysmMoment: InUniverse ItMakesSenseInContext, and then she [[spoiler:[[WhenSheSmiles smirks on]] TheStinger]].
-->'''Geji-nee''': ''Why I said "[[spoiler:kiss my forehead]]" just now is unknown. Because it may be a bug, it's under investigation.''
* GainaxEnding: [[spoiler:The supposed "ending" to Gunvarrel that was leaked online.]]
* GoodOldRobot: Tanegamachine-san. It is later upgraded for the Robo-One tournament as Tanegamachine-san ''Advance''.
* GovernmentConspiracy: Committee of 300, some kinda in-universe version of real-world conspiracy theories floating around on the net.
* GratuitousEnglish: [[https://www.youtube.com/watch?v=YJHAG3bnfJ0 "Too expensive!"]] though it's only heavily accented. [[spoiler:Also Aira's password "hidden hand".]]
* HumanPopsicle: The real [[spoiler: Airi is a girl with a terminal, incurable disease. Kimijima Kou put her into suspended animation until the world finds a cure for her condition.]]
* HumbleGoal: Akiho just wants to finish a HumongousMecha project started by her sister before graduating.
* HumongousMecha: The purpose of the robotics club is to build one based on a worldwide famous anime.
* [[spoiler: IKnowYoureInThereSomewhereFight: The final battle is an even balance of this and [[HumongousMecha Mecha vs Mecha fighting.]]]]
* IKnowMortalKombat: With some help from Frau Koujiro, Aki and Kai were able to program their hobby robot to be controlled via video game controls from ''Kill Ballad'' for a tournament. [[spoiler:This control system was later used to pilot the Robotics Club's giant robot for the final battle.]]
* ImagineSpot: Junna has one of Subaru modeling for a naked photoshoot, which he [[BreakingTheFourthWall quickly destroys.]]
* InterruptedSuicide: [[spoiler: When Kaito wants to talk to Frau Kojirou and she isn't answering her intercom, he takes a big stone to smash the glass front door and to break into her apartment, [[BathSuicide to find her in her bathtub, holding a knife in her hand,]] thankfully before she can do the deed.]]
* JustBeforeTheEnd: The characters point out how the Earth is currently experiencing abnormal weather, such as scorching hot winters in Russia and snowstorms in the American West Coast. Solar flares are also messing with electronics worldwide. [[spoiler:Kimijima claims that this is because the Sun is about to explode but it is later revealed claims of such were just elaborate, fake propaganda used by Kimijima to distract public attention from his goals.]]
* LapPillow: Akiho and Kaito in Episode 8.
* LethalChef: Invoked with Irei's special nikuman. An abomination of [[NauseaFuel spicy dough with passionfruit and cheese filling.]] See EatThat.
--> '''Kaito''': "It is truly one of the Devil's own inventions, from the pits of Hell itself".
* LikeBrotherAndSister: Kaito and Akiho.
** [[spoiler: Until episode #21, were Kaito confesses his love to her and she reciprocates with a kiss.]]
* LoopholeAbuse:
** Even though Kaito and Akiho lose the hobby robot tournament and their bet with the vice principal, they point out that the winner, Subaru, is also a student in their school and blackmail him into saying he's part of the robotics club, so they still technically won.
** Subaru uses this against Kai as well; when Kai uses his usual dodge of demanding that someone beat him in Kill-Ballad before he does anything, Subaru simply continues challenging him to consecutive fights until he won, since there's no limit to the number of rounds specified.
** When Kai is given the conditions/flags to unlock the Kimijima reports, such as completing a lap in a certain amount of time at an out of business go kart track, he simply uploads a fake time as if he did race it, as there was no way he could realistically do it. In another, he's required to hit a bulls eye at an archery target. However, the flag never specified how far away he has to be, so he shoots at it from a few feet away to ensure a bullseye. Another report requires him to put rocks on a shrine without them dropping off, and he tries with big rocks at first but fails. He later puts small pebbles on, and it still satisfies the flag since it technically never specified how big of a rock had to be placed on it.
** Akiho asks Kai to get Frau to help with the programming on the mecha's motor in episode 13. He tells her he needs to be defeated in Kill Ballad first before he'll do it. Since she's terrible at the game, she gets Nae to defeat him instead.
* MediumBlending: The anime uses three types of animation throughout: there's the standard anime style, the video game 3D style for ''Kill Ballad'', and the 80s Anime style with touches of modernization for segments that have ''Gunvarrel''. The blending comes in when the anime is able to render both game and the anime at the same time, which is rather tough to pull off but is performed ''[[SceneryPorn spectacularly]]''.
* {{Meido}}: One of the Pokecon's applications allows Kaito to see Akiho dressed in such a costume with [[UnusualEars cat ears.]]
* TheMenInBlack: At the end of episode 7 and the beginning of 8, some men in black suits along with a mysterious lady shows up and forces Akiho and the others to go with them. However, it's subverted when the lady introduces herself as Nae Tennoji, and that she works for JAXA and wants to help them build their mecha after seeing them at the Robo One Tournament, along with the interview Akiho gave earlier.
* MythologyGag: When asked if it's possible to hack the Iru-O system, Kona says that's it's just as hard as [[SteinsGate hacking SERN's database to steal classified information.]]
** In episode 20, when Frau sees a plane landing in front of the club's hangar, she wonders if [[SteinsGate it's a handsome time traveler from the future]].
* [[spoiler: NiceJobBreakingItHero: In Episode 17 Kai downloads the 7th Kimijima Kou file, which is an executable that distributes the other 6 Kimijima Kou files to everyone using the IROU system.]]
* NoExceptYes: You are led to believe that [[spoiler:the killer of the entire staff of Gunvarrel]] was actually [[RoomFullOfCrazy crazy enough to begin with]] but the others involved were not. It turns out later on [[spoiler:that the creators were ones who were actually [[BrainwashedAndCrazy crazy because they were brainwashed]] and the person who killed them involuntarily got free of said brainwashing,]] but this came after the revelation that [[spoiler:Gunvarrel was supposed to make ''everyone'' crazy.]]
* NowOrNeverKiss: [[spoiler: Kai asks for one from Aki before he pilots the Super Gun Pro-1 into a potentially SuicideMission.]]
* PaperThinDisguise: Averted with Kai who easily sees through it. Akiho on the other hand...
* PoweredArmour: Irei, the owner of the Irei Shop, has a non-military variant: She uses an exoskeleton (it's not a full one, just for her legs) to move her legs (most likely connected to her nerves, since she doesn't seem to operate any controls while she walks) after an unspecified accident. [[http://imgur.com/qn6Dm Click here for an illustration]]. [[spoiler: Later, she's killed by someone hacking it and making her walk off a cliff.]]
** Misaki is later seen wearing a full body version of the exoskeleton, which gives her insane strength and agility, as well as the ability to interface directly with electronics.
* RealRobot: The hobby robots are pretty much fine tuned versions of the toy robots available now. Gunvarrel, being from a ShowWithinAShow , Is pure super robot- however the replica built by the club has a different design in order to actually be able to stand without falling apart.
* RelationshipSabotage: Akiho does this in episode 9, after noticing Nae and their teacher Mitsuhiko getting a little too friendly for her liking at the festival.
* SavvyGuyEnergeticGirl: Again, Kai and Aki.
* SequelHook: Kou claimed, that the copy possessing Misaki is only one of many and that he'll be back.
* SharedUniverse: Robotics;Notes shares setting with its two predecessors: ''VisualNovel/SteinsGate'' and ''VisualNovel/ChaosHead''.
** Episode 8 shows the return of [[spoiler:Nae Tennoji from Steins;Gate]]
** Episode 9 shows that Kai is possibly online friends with NEIDHART aka [[ChaosHead Takumi]].
*** He is also seen browsing posts made by [=DaSH=] and [=KuriGohanandKamehameha=], who are [[VisualNovel/SteinsGate Daru and Kurisu]], respectively.
** According to Frau Kojirou in episode 11, hacking into IROU is as impossible as [[VisualNovel/SteinsGate hacking into SERN and stealing their files... Really? Say that to Okabe!]]
** In episode 13, five of the nineteen images included Mayans, Nuclear Explosions, and [[ChaosHead the Shibuya 107 Building]].
** In episode 14, if you look closely enough, a poster of [[VisualNovel/ChaosHead Seira]] can be seen in the background of Maguyan's room.
** Episode 19 has multiple references to SteinsGate and ChaosHead, such as Nae's codename being "S_Braun", SERN providing black hole warheads to the Committee of 300, and the Committee having improved upon the Noah illusion technology.
* ShoutOut: The very first moments of the first episode are this to its [[VisualNovel/SteinsGate predecessor.]]
** [[VisualNovel/ChaosHead Whose eyes are those eyes?]] and the [[VisualNovel/SteinsGate divergence meter]].
** In episode 4, Misaki Senomiya shouts "[[TheRightStuff Go, hot dog, go!]]" during the rocket launch.
** Aki quotes [[MobileSuitGundam Char Aznable]] when she puts her glasses on.
** A small GagSub from a translator group refers Mister Pleiades as [[StarDriver Galactic Hero Tauburn]].
** The anime title card contains an {{Engrish}}y rendition of ''{{Invictus}}'' last line:
--->I am the captain of my soul.
** In episode 6, Aki asks if she can call Kona [[MobileSuitGundam Frau Bow]].
** In episode 8, Aki takes the ClaspYourHandsIfYouDeceive stance, and Subaru [[LampshadeHanging calls it]] the "[[Anime/NeonGenesisEvangelion Gendo]] [[MemeticMutation Pose]]" by name.
** The game that Kaito plays during the storm has a logo that looks a lot like ''VideoGame/StreetFighterII''.
** In episode 10, the ''[[Franchise/StarTrek Starship Enterprise]]'' make a cameo.
** In episode 11, when Kaito asks Kona to hack Iru-O, she tells him that it's a hardcore thing to do, like [[VisualNovel/SteinsGate hacking into SERN and stealing their data]].
** Episode 13 shows that Misa's e-mail address is [[Anime/MobileSuitGundam0080WarInThePocket misa_rx_78nt_1@delumail.jp]].
** The Giant Robot "Achillesimo" at the expo in animé episode #18 is shown bending steel rods and is named after the [[GreekMythology famous hero from Greek Mythology with the bad heel, Achilles]]. He even has a kinda-ancient-greek helmet.
** One of the trophies is called "UMISHO ga! Kimeta--!", a reference to [[http://www.youtube.com/watch?v=DO38IFrs9wU this awesome moment in fighting games]].
** In episode 22, Gunpro-1's internal batteries can only [[Anime/NeonGenesisEvangelion power it for five minutes.]]
%%DO NOT add references to Steins Gate and Chaos Head to the Shout Out section. Put them under Shared Universe or Mythology Gag instead.
* ShowWithinAShow: The Gunvarrel anime, a standard SuperRobot show about a boy called Dotou Genki and the HumongousMecha he pilots, Gunvarrel.
* SmoochOfVictory: [[spoiler: Frau gives one to Kai.]]
* SpoilerOpening: The opening makes it clear who joins the Robotics Club.
* SuddenDownerEnding: An in-universe one occurs when [[spoiler:the final episode of the Gunvarrel anime is leaked. All the robots sacrifice themselves to power a giant cannon that fires into the sun, causing a solar storm that not only [[KillEmAll kills the main villain, but all of humanity as well.]] One of the protagonists sacrifices herself to save her partner, who is left to wander the ruined Earth alone. [[HeroicBSOD Akiho reacts poorly to this ending.]]]]
** In an example pertaining towards the series itself; one could count episode 16 as having such.
* SquareCubeLaw: Discussed in-universe as the reason why building GunPro-1 is so impractical, and why building GunPro-2 will be even harder from scratch.
* TheGoodGuysAlwaysWin: [[spoiler: Kaito's final line to Kimijima.]]
* ThereIsOnlyOneBed: Episode 18 between Kai and Aki
* ThirdIs3D: Which is [[GenreBusting unusual]] for the visual novel genre. The majority of the game's dialogue is performed by 3D models instead of 2D portraits.
* TitleDrop: In "Thank You Berry Much"
* TooDumbToLive: Yeah Subaru, stand next to the giant robot when there's a powerful wind blowing!
* TrueCompanions: The Robot Club members are gradually becoming this as of Episode 14.
* TurnedAgainstTheirMasters: Thousands of Robots in Tokyo go berserk after someone hacks them. [[AIIsACrapshoot Totally unexpected!]]
* TwentyMinutesIntoTheFuture
* UnwittingPawn: [[spoiler:Kaito to Kimijima Kou. Then again, that's how CrazyPrepared Kimijima Kou really was]].
* UrbanLegendOfZelda: InUniverse, as the wildly popular Gunvarrel anime (the HumongousMecha anime that Akiho wants to build) has had no official ending for several years, even though it had a running of ''155 episodes''. It's ended up being wildly rumored that the anime itself had an ending, but the general fanbase was sad to see it end on such a {{Cliffhanger}}.
* VirtualGhost: [[spoiler: Kimijima Kou's "ghost" can be seen with these smartphones in the series.]]
* VomitDiscretionShot: When Frao Kohirou realizes, that someone has taken over her Twitter account published a fake confession of her taking over robots and leaking the last Gunvarrel episode.
* [[spoiler: WetwareBody: Airi and Misaki are controlled by Kimijima's VirtualGhost]]
* WhamEpisode:
** Episode 6 -- Subaru's father shows up at the robotics club hangar and finds out that his son is still showing interest in the "toys" instead of taking over the family fishing business as he promised to two years earlier. He punches his son and slams Subaru's robot onto the ground. Though Akiho barely stops Subaru's father from stomping on it, Subaru tells her to dispose of it. The shock of watching Subaru being forced to abandon his dreams also triggers an "Elephant-Mouse Syndrome" attack on her as the episode ends.
** Episode 13 -- A solar flare fries Tokyo, Frau's online account is hacked and claims to be the one making robots attack people in the already devastated city. [[spoiler:[[InterruptedSuicide Then Kaito finds her in the bathtub with a knife in her hand]] and [[InterruptedSuicide preventing her nkilling herself.]]]]
** Episode 16 -- [[spoiler:Irei is killed when her exoskeleton is hacked and forces her to walk off a cliff.]]

** Episode 19 -- [[spoiler:Senomiya Misaki moves to carry out Kimijima Kou's plan by shooting SERN-built black hole bombs into orbit and fiddling with the magnetic field of the earth, killing 5 billion people in the process. Sawada Toshiyuki tries to prevent this. Kimijima Kou [[BrainUploading uploads himself]] [[VirtualGhost into the IROU network]].]]
** Episode 21 -- [[spoiler: Kaito confesses to Akiho, Akiho kisses him. Subaru and Frau Kojirou are jealous.]]
* WhatTheHellHero:
** Subaru asks this of Ahiko after she turns down JAXA's support to build a working mecha, because they wanted her to start from over scratch, while she wanted to continue working on Gunbuild 1. He was being reasonable given that the club's attempt at a robot was terrible due to not being able to get the parts that the blueprints required, but Akiho wanted it done for mostly sentimental reasons, to finish her sister's work in the club.
** Junna experiences this from her grandfather after she accidentally causes one of his robots to fall on top of her, which also sets off her fear of robots.
* WhatHappenedToTheMouse: We never find out the final fate of [[spoiler:Frau's mother]]in the anime adaptation.
* YaoiFangirl: Frau Kojirou and Jun.
* XanatosGambit: [[spoiler:The Kimijima Reports are actually lies written by Kimijima to manipulate readers into carrying out his true plans. He's not trying to prevent a catastrophic solar flare, he's trying to ''cause'' one.]]
** [[spoiler:CrazyPrepared: According to Episode 20, he planned the ''entire'' setup, scenario, and endgame that has occurred in every ''other'' episode. ''Everything'' was all according to plan.]]
